Web Accelerator not responding to iControl invalidation commands

Greetings. Your actual XML message in test_f5.txt is valid; it works for me with the appropriate change to the app name and the URI.

I have not looked at your Java program. But here is a pearl of wisdom followed by a very simple example which you might use as a better starting example than the rather sordid Perl script to which I think you're referring.

Search your log /var/log/tomcat/catalina.out for an error similar to this:

Exception in thread "Thread-5" java.lang.NullPointerException
        at com.f5.wa.esi.server.InvalidationSocketServer.processInvalidation(InvalidationSocketServer.java:157)
        at com.f5.wa.esi.server.InvalidationSocketServer.run(InvalidationSocketServer.java:103)
        at java.lang.Thread.run(Unknown Source)

If this error occurred since last time you restarted tomcat, then you will find yourself in an unfortunate predicament, a predicament subversive to developing your working invalidation script. Because subsequent iControl calls to the method will silently fail in the meantime even with a properly base64 encoded XML message. Restart the tomcat service for to recover.

tmsh restart sys service tomcat

The condition occurs after certain invalid / corrupt messages to esi_invalidate_content, which makes it easily stumbled upon trying to develop a new script.
