When configuring JRebel on my remote server (JBoss on linux) I have configured the JVM arg as
-javaagent:/home/user/jrebel.jar" -Drebel.remoting_plugin=true
The jrebel.jar is absolutely definitely in that location, yet the server fails to start with the error:
Error opening zip file or JAR manifest missing : /home/user/jrebel.jar Error occurred during initialization of VM agent library failed to init: instrument
So the arg is oviously being passed to the JVM correctly, but for the life of me I can't work out why it can't find the jar. I've been through every Zero Turnaround article I can find + looked at the solutions that have resolved it for other people, but no luck. Any ideas?
Turned out to be a permissions problem - the JBoss user didn't have the permissions to access the directory that I had placed jrebel.jar into.
Would have been nice to have a more meaningfull error - e.g. 'permissions denied'. Shows my lack of Linux knowledge though I guess.
After the jar was moved to a directory within the JBoss installation + the jar owner was changed to the JBoss user and Read/Write/Execute permissions added, all is well.
