JMS Messaging Modular Input 1.5.1: How to troubleshoot error "Unable to initialize modular input "jms"..."?

[tawollen]

Get the following errors when trying to start Splunk with the JMS Messaging Modular input.

I'm getting this error too. WHen logged in as Splunk user i get this:
[code]
echo $JAVA_HOME
/usr/java

java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
[/code]

I'm at a loss as to what could be wrong.

No where in the documentation does it say to change jms.py. So it is pretty difficult to answer this question as you are basically running your own code now that is not tested in the official release.

My advice , stick to the documentation.

Secondly , you might want to post your inputs.conf configuration , details of the environment, an overview of all steps you have performed to date etc.. , so that I have some context to actually start with for an answer.

That seemed to work until we configured the queue. Now getting the following errors. Not sure if it is related to the non-standard Java or something else.

In order for JMS to run, either java must be defined in the JAVA_HOME environment variable or be in the path.

If you have Java installed in a non-standard path, you must currently modify a line in jms.py.

From

  if (not os.environ.has_key('JAVA_HOME')):
     JAVA_EXECUTABLE = java'

To

  if (not os.environ.has_key('JAVA_HOME')):
     JAVA_EXECUTABLE = '<correct path>/bin/java'
