[rules-users] Error with conversion from .brl to .drl file

[Fnu Mahalakshmi]

Hi Giovanni,

The classpath shows the commons jar added under UserEntries.

I am getting another error when I try running the program now :

Exception in thread "main" java.lang.NoClassDefFoundError: org/drools/brms/server/util/BRXMLPersistence
	at com.org.RulesTest.main(RulesTest.java:40)
Caused by: java.lang.ClassNotFoundException: org.drools.brms.server.util.BRXMLPersistence
	at java.net.URLClassLoader$1.run(Unknown Source)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
	at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
	at java.lang.ClassLoader.loadClassInternal(Unknown Source)
	... 1 more

This was not coming till now.
The exception come at the line when the .brl file is to  be processed.
I am not able to figure out. I tried googling the error. But no use!

Please help!
Thanks 
M

Are you launching the application from within eclipse?
Have you checked the classpath of the launch configuration? You can see it
by right-clicking the .java file and then selecting "run as --> run
configurations..."
Does it show the commons jar?
