Hi Guys,
I am trying to debug the Java compute node. I am not able to debug. I am getting error "Local variables unavailable" at code

| MbMessage outLocalEnv = new MbMessage(contact admin.getLocalEnvironment()); |
Can you pls let me know what i am missing during compilation.
Thanks |

I hope your contact admin really was outAssembly...
As you are looking to work with the output local environment. I would expect the input local environment not to be mutable...
Of course it all depends on what type of message building template you initially chose and on how your outAssembly was created...
On the other hand I would not use new MbMessage as the output of outAssembly.getLocalEnvironment() is already an MbMessage...
I get the new Message thing, but you would still have to create a new output assembly passing the outlocalEnv... so why not just retrieve it from the current outAssembly and modify it?? It most likely already got copied from the input assembly to the output assembly at the point where the code hits the user part of the evaluate method...
Don't try to emulate ESQL exactly. On the JCN there is no property to determine which part of the assembly gets propagated to the output and no need to copy the input local env to the output local env.
This happens by default in the outAssembly constructor... before you hit the user part the evaluate method...
Have fun

Hi Chris,
You are forgetting that the java reference is just a "pass through" reference to the underlying jni that actually manipulates the message in C.
Unlike ESQL you will only see the reference and not it's content as that content is only accessible through the corresponding method or through MbElement.getObjectAsString(); .
So the only values you may see in JCN debug are the leaf values you are looking at in the code. Any tree node will just be a reference.
May be the output of MbElement.getName() into a debug variable would help you determine where in the tree you actually are.
Working as designed...
Have fun

I remember speaking to one of the developers a while back and they say it would be possible to expose the logical tree variables in a similar way to how it is seen in ESQL.
I guess it would just need someone to raise an RFE and enough people to get behind it - it'd get my vote  |
