Hi, I would like to work on this issue

@krisstern Hmm. I'm not sure if this one is still available. I see that it hasn't been assigned to anyone but at the same time I remember seeing pull requests on this topic so I'll have to ask @jagpreetsinghsasan to confirm if he is working on it or not just to be sure. Jagpreet could you let us know if this is really available?

[jagpreetsinghsasan]

@petermetz its available if we are to generate the java code using -g java argument. Can answer this question once the ongoing conversation here gets resolved: https://github.com/hyperledger/cacti/pull/2973#issuecomment-2042130024

Yeah, it's my fault, sorry about the misunderstanding @jagpreetsinghsasan and @krisstern .
Basically what I meant by "java clients" is JVM in general (e.g. Kotlin in our case)

[jagpreetsinghsasan]

Based on the conversations I had with @petermetz around this on my previous PR, I will create new issues to address the same.
Because when I created this task, the intention was to generate the jars using Java codegen specifically (which is very buggy at the moment). But now with the clarification. I will create another issue listing all the plugins which needs the jars (can be generated by either kotlin/java, whatever codegen works).
@krisstern I will tag you in the comment section of that task.

@jagpreetsinghsasan That would be great! I would appreciate it
