Deploying the JavaScript Engine in Camunda
Once we have implemented the JavaScript engine in Camunda, we need to deploy it in the Camunda environment. Here are the steps to do that:
Copy the compiled JavaScript engine jar file to the Camunda lib directory.
Add the engine configuration to the Camunda configuration file (camunda.cfg.xml). The configuration file should include the following properties:
Engine name
Engine class
Engine configuration URL
Engine configuration file name
Restart the Camunda engine after adding the engine configuration to the configuration file.
Test the JavaScript engine by executing a BPMN process that has a script task that uses the JavaScript engine.
If the JavaScript engine is working as expected, we can deploy it to a production environment.
To deploy to a production environment, we need to perform the same steps as in a development environment, but with additional security and performance considerations in mind.
In conclusion, adding a JavaScript engine to Camunda is a straightforward process that involves writing the JavaScript engine code, compiling it, deploying it in the Camunda environment, and testing it. With a few modifications, we can use the same JavaScript engine for multiple Camunda projects, saving time and effort in the long run.
Testing and Debugging the JavaScript Engine in Camunda
After deploying the JavaScript engine in Camunda, we need to test it to ensure that it is working as expected. Here are the steps to test and debug the JavaScript engine:
Execute a BPMN process that has a script task that uses the JavaScript engine.
Verify that the script task is executed correctly and produces the expected output.
If the script task does not produce the expected output, we need to debug the JavaScript engine code.
Camunda provides a debugging interface in the Camunda Tasklist that allows us to inspect the script task execution, variables, and outputs. We can use this interface to debug the JavaScript engine.
If we are unable to resolve the issue with the Camunda Tasklist debugging interface, we can also use the Camunda Cockpit to inspect the script task execution, variables, and outputs.
In addition to the Camunda debugging interfaces, we can also use a standalone JavaScript debugger, such as the Chrome DevTools or Firebug, to debug the JavaScript engine.
If the issue still persists after using the Camunda debugging interfaces and a standalone JavaScript debugger, we can log the execution of the script task and the values of the variables and outputs.
Once the issue is resolved, we need to repeat the testing process to verify that the JavaScript engine is working correctly.
In conclusion, testing and debugging the JavaScript engine in Camunda is a critical step in ensuring that the engine is working as expected. Camunda provides several debugging interfaces and tools that allow us to debug the JavaScript engine effectively. Additionally, logging the execution of the script task can also help us identify and resolve issues with the JavaScript engine.
Integrating JavaScript with Camunda
In this part, I’ll walk you through the process of integrating your custom JavaScript engine with Camunda. This integration is crucial to make sure that Camunda can execute your JavaScript expressions correctly and the correct runtime environment is used.
To integrate your JavaScript engine with Camunda, you need to implement the org.camunda.bpm.engine.impl.scripting.ScriptEngine interface provided by Camunda. This interface requires you to implement a few methods such as eval, execute, setScriptEngineFactory, and unsetScriptEngineFactory.
The eval method is used to evaluate a single JavaScript expression and return the result. The execute method is used to execute a full JavaScript script, which may contain multiple statements. Both of these methods should return the result of the JavaScript expression or script.
The setScriptEngineFactory method is used to set the org.camunda.bpm.engine.impl.scripting.ScriptEngineFactory for your custom JavaScript engine. This factory is responsible for creating instances of your custom JavaScript engine for use in Camunda. The unsetScriptEngineFactory method is used to unset the script engine factory and remove it from Camunda.
Once you have implemented the ScriptEngine interface, you need to register it with Camunda. To do this, you can add a file named org.camunda.bpm.engine.impl.scripting.ScriptEngine to the META-INF/services directory in your classpath. This file should contain the fully-qualified name of your custom JavaScript engine class.
At this point, your custom JavaScript engine should be fully integrated with Camunda and ready to use. To test the integration, you can create a process definition that uses JavaScript expressions and verify that they are executed correctly by your custom JavaScript engine.
In conclusion, integrating a custom JavaScript engine with Camunda is a straightforward process that involves implementing the ScriptEngine interface and registering it with Camunda. With this integration in place, you can use your custom JavaScript engine in your Camunda processes and take advantage of the powerful scripting capabilities that it provides.
Testing and Debugging Your JavaScript Engine
Once you have completed all the previous steps, it’s time to test your JavaScript engine to make sure everything is working as expected. Before you start testing, it’s important to have a clear understanding of what you want to achieve with your engine and what kind of behavior you expect from it. This will help you to determine whether your implementation is correct or if there are any bugs that need to be fixed.
There are several ways to test a JavaScript engine, including manual testing and automated testing. In manual testing, you will execute your engine in a test environment and observe its behavior. This approach is useful when you need to test specific scenarios or edge cases. On the other hand, automated testing is more efficient and less prone to human error. You can write test cases that will execute your engine automatically and check whether it produces the expected results.
Debugging is another important step in testing your JavaScript engine. If you encounter any issues or errors, you need to be able to diagnose the root cause and fix the problem. One way to debug your engine is to use the built-in debugger in your development environment. You can set breakpoints, inspect variables, and step through your code to see what’s happening at each stage.
Another way to debug your engine is to log messages to the console. By logging messages, you can see what’s happening inside your engine and diagnose any issues. This approach is particularly useful when you’re working with complex systems or when you need to track down hard-to-find bugs.
In conclusion, testing and debugging your JavaScript engine is a critical step in the process of adding it to Camunda. By testing your engine, you can ensure that it works as expected and that it produces the desired results. Debugging is also important to help you identify and fix any issues that may arise during the testing process.

Microservice orchestration is something that we all have to do in the enterprise space. Whether you’re using something like Camunda, Kafka, Temporal, or a million other things, you have to have a way for one system to call to another, deal with exceptions and timeouts, escalations retry, throughput, logging and security, multi-tenancy, and more. You have to solve that problem.
Now, are you going to solve that problem with a home brew solution or are you going to use an off the shelf product for that? And this, I think, is sort of a fundamental perspective that we need to be thinking about. There are places where I think a home brew solution makes sense. So if you are doing something super idiosyncratic to your industry and you’re using your own proprietary protocol, I can imagine that an off-the-shelf engine wouldn’t necessarily work for you. But for the most part, the majority of us don’t live in that space.
The majority of us are trying to do fairly conventional things. We want to make a restful call here, make a GRPC call there. We want to talk to the database, get some information, log all of it, encrypt it, and update this other data source. For that purpose, you can either write custom code: If “x” happens, then do “y” unless there’s a timeout, and then escalate and send it to this email, and so on and so forth.
Or you can use a microservice orchestration engine. Now, of the microservice orchestration engines that are out there, you can take something like Kafka, build logic around it and establish your own message protocols and use that as a mechanism to transport messages back and forth.
But you still have to build logic, NEM, and even pseudo grammar around that, right? So when we put messages in the Kafka queue, we do this, we do that, and so on and so forth. Or you can go hardcore. You can write IF statements that are nested. “Hey, if this happens, unless this time’s out, retry three times,” and so on and so forth inside of your code.
Or you can use some kind of a workflow engine. The idea of the workflow engine, or languages that are specific and targeted for solving this particular problem, make a lot of sense in the same way in that using something like SQL makes a lot of sense when you’re dealing with data access. This is because it’s not a generic problem, it’s very specific to a particular type of adventure that we’re on. It makes sense that you would want to be looking at a specialized tool for that – just like the carburetor in your car is a specific tool that does a very specific functionality. You don’t want to have to go out and rebuild a carburetor every time you want to drive to the grocery store. That’s where these engines come in. At the end of the day, you’re better off using a tool than banging two sticks together in order to make fire.
Cap’s Loyalty to Camunda
My loyalty to Camunda is based explicitly and only on its excellence. If it were another company that was excellent in this field, that’s the one I’d be working with, but I’ve worked with IBM, Pega, and Appian. I’ve done a lot of different stuff in this space, and from a pure performance perspective, I don’t know of any engines out there — any service orchestration engines — out there that are better than Camunda. What I like about it is that it’s open source, so if you want to take on the feeding and the maintenance of it, you can do that and you don’t have to work with a vendor.
At the same time, there are SaaS offerings for it offered by Camunda — especially with Camunda 8 — where they say, “Hey, we’ll take on the infrastructure and the security, and you just write your workflows and your processes.” At the end of the day, the majority of the people who work in this space need to solve fairly common problems, but just because they’re common doesn’t mean that they’re easy. Our ability to be able to articulate our problem and our ability to be able to articulate the solution for that problem in a notation specifically designed for that just makes a lot of sense.
I also like the visuals. I like seeing this step go to this step and then go to this step. I like it because I can go to my business partner and go, “Hey, is this right? Am I doing this right?” This is because they know the business side, I know the technical side, and the pictures help us draw that together. I also like the fact that when it is explicitly drawn out, then my technical teams have more clarity in terms of how to manage it, how to change it, what the side effects are, and how to version it. Everything you need is right there. Now, we can focus our energies on how to do an efficient read from a database, what the business logic rules are that we need to implement as opposed to the metadata, and how we’re going to define all of this.
There are tools out there like Temporal, which I think is an exciting tool in the space, but fundamentally, it is a code-based platform as opposed to a visual platform. I fundamentally believe that there’s a finite number of things that you can keep track of in your head when you’re looking at it from a code perspective. For example, most people can bring up an image of the Mona Lisa in their mind, but you’re gonna have a hard time remembering 50 pages of Shakespeare, verbatim. Code and text is harder when it gets complex, where diagrams and images are how our brains are wired. We’re hunter gatherers. We think in terms of visuals and the ability to distinguish differences and colors. So, with all that said, the ability to deal with encroaching complexity is better dealt with with a diagram-based tool than a code-based tool.
Validating Camunda’s Ability to Help
You have to have a high standard. You should always be thinking days and weeks, not weeks and months. You should say, “Hey, I have a test case. I want to make a call to these three restful services, I want to deal with timeouts, escalations, and routing roles, and I want to get this done in two weeks. That is an empirical test that is not subjective. You could actually do that. The trick is going to be making sure that you have somebody to help you.
Whether it’s a partner like Capital BPM or some expert that you know out in the wild, bring in someone who knows how to drive this car so you get the experience of what it’s like if you had this car. You will get there by just figuring out the technology yourself, but you’re not gonna know it on Day 1. But that’s not the important thing. The important thing is to have this vehicle cover the terrain that you need to cover in the time that you need, plus the safety and the security that you need. That is an empirical question, and engineers love empirical questions because we don’t have to argue. We can just see what happens.
I love that approach. I love it philosophically and I love it practically. I would recommend, you know, come up with a use case where you want to do specific tasks and then start the timer. How long is it going to take you to do these things? Is it worth it? It is better to get someone who knows how to do it and see if that works for you. Be empirical.
Overcoming Camunda’s Biggest Weakness
Like all technologies, Camunda has its weaknesses. The main weakness is going to be the fact that it is a different paradigm than what your normal techies are used to. You’re drawing diagrams as opposed to writing code and that is, a fundamental paradigm shift for your traditional programmers. If they can understand, and adapt to the fact that Camunda is the orchestration engine, it acts like a conductor in an orchestra. It will say a little more violin, a little bit more cello, and whatnot. If they understand that, that’s what Camunda does for them.
The things that they’re doing — talking to the database, making a restful call, updating the Kafka queue — those things can still be written in traditional code. You can focus on the excellence of your development team on those atomic tasks. Then let Camunda compose them into a hole. That is the strength and the weakness of it. That is also the place where, from a mindset perspective, where you need the most flexibility. I would say that can definitely be a challenge.
Where Capital BPM Steps In
Typically what we do is we help customers come up with a valid challenge. Within a certain amount of time — both from a development amount of time and an execution amount of time — we help them articulate the problem, and then we help them come up with an objective test that determines whether it’s possible to do this or not. And again, this can be a matter of weeks.
In those weeks, we should be able to build a proof of concept that shows you whether it’s possible to do this or it’s not possible to do. Camunda is not a silver bullet. There are no silver bullets, which is a sad state of affairs, because there are monsters out there. But even as we need to be able to slay these monsters, there are practical things that we can do, and some of these practical things are just a matter of trying it out, seeing if it works, and taking notes on what happened. And that’s where CapBPM can help. We know this technology very well; you know your business domain very well. We can put those together and figure out if this is a useful tool for you or not.
What are some challenges that I’m likely to face when trying to deliver my first command to project?
Generally speaking, when you are doing a BPM or process orchestration project, the hard part is not articulating out the steps like your business people, your IT people, they know what those should be. The hard part is the nitty gritty of actually talking to the integration steps, like, for instance, you’ll wanna make a restful call, but there’ll be some weird thing in the header and you won’t be able to call it. The team that’s responsible for that won’t be able to meet with you until, let’s say for example, next Tuesday. When you do, they’ll give you a token. You’ll try, and it doesn’t work because you’re in the wrong environment. That kind of stuff drives you nuts. Integrations are hard and they’re hard because they’re imprecise, so the pain is going to be in the nuts and bolts of actually talking to those external systems. Seems like it should be easy, but it’s always painful. Therefore, that’s the place that I would start.
Now, typically what I do of my projects, is I will always stub those out. If there is an APIM system in place like an Apigee, MuleSoft, Kafka or something else, I will use that and I will stub out a restful API call. Then I’ll let the Java folks, .net folks, or whoever, figure out the mechanics. When that’s done, I’ll turn the sprocket and I’ll actually get the payload that I expect. If that’s not in place, then I’ll put in essentially stub, so instead of calling the service to say, “Get a customer from the database”, I’ll actually say, “Hey, what does the customer look like? What does the stub look like?” I will hard code that while the rest of the team is dealing with the technical difficulties of making that integration work.
The reason that I do that is because if I’ve got a 10 step process and the very first step requires that I load a customer, I don’t want to be stopped on working on the rest while this problem gets trafficked. I’ll just take “John Smith” as a customer, and for example, we know that he has 17 fields. (first name, last name, age, etc.) We’ll use that to drive the process. In the meantime, I’m going to have one of my smart guys figuring out why this restful API call doesn’t work. That allows us to make progress on the process side while concurrently working on progress. On the technical integration side, one of the ancillary benefits is that when you’re doing testing, you know how much of your time is being spent on the process and how much of it is being spent on the integration.
How do you know that the payloads will have fidelity and really be true to what you need?
You can imagine a scenario where we have a customer that’s coming back and we expect the last name field to be named, “last name,” but really in the database, it’s called “surname.” When we actually make the thing work, it breaks because we were expecting last name and we got “surname,” and our code doesn’t know how to deal with it. There is no way to know that every single time off the bat.
However, I submit that it doesn’t matter. I submit because the cost of integration is cheap due to the fact we’re stubbing it out. Actually making the change from “last name” to “surname” to “middle name” is something that we can evolve on. These are problems that you can negotiate and that you can solve as you’re going through the system. The trick, as always in the enterprise space for the last 15 to 20 years, is iteration. You do it again. You make some mistakes, shake yourself off, and you do it again, and you make it better, right?
You’ve gotta embrace that philosophy. You deal with a customer and they have 17 fields, and maybe you get six of them wrong. That’s okay. Move forward with what you can, and then fix the other parts of this that is the heart of what I call “shark architecture.” And to me, “shark architecture” means that like a shark, you have to swim in order to be able to breathe. You have to move forward. There is no stopping. We don’t assume that we don’t know what to do because the team is not done with whatever they are dealing with. That doesn’t happen on the projects where I’m involved and I get to keep my sanity.
With all that being said, I would say make some mistakes. Go forward, come back, iterate on it, make it better and better. This isn’t just for delivery, this is for post-delivery. We expect processes to be provable. We expect to be able to make changes, right? We need to work out our discipline and our cadence for how we incorporate change into what we’re doing. The big mantra of Agile programming has always been embrace change. Let’s do that, right? Let’s do this thing that we’ve been talking about all this time. I’m a big proponent of this. Just get in there, get stuff done, make some mistakes, learn from them, and do it better.
How do I deal with the fact that in the real world there’s gonna be a lot of variation of the nature of the data and your approach might lull us into a sense of complacency?
You need synthetic data that is auto-generated by an AI. It is fair to say, for example, that we’re going to bring back “John Smith” and he is going to be a specific payload, but it’s incredibly easy now to say, “Hey, we’re going to bring back one of random 20 customers. One will be John Smith and one will be Joan Stevenson, and so on and so forth.” The data variance can be dynamically changed by an AI. It’s synthetic data that you described using a grammar, and there are open source tools that can do this for you. You can talk to your favorite AI tool. They can do this for you, or you can just code it up. This is not going to be one hundred percent. It’s not going to cover you for every variation, but it is better than nothing.
Remember, we need to move, we need to make progress. I would much rather have a process that breaks when there is no customer identification number than have a process that hasn’t even been implemented because we’re waiting for everything to be perfect.
