I checked the jboss-logging.jar which is the only jar has "org.jboss.logging.BasicLogger" class in my classpath.

I have no idea regarding the exception. this is working fine with standalone JVM.

Please help me to solve the issue.

thanks in advance. amal raj.

If you want to use a library (like Infinispan) which uses the more recent JBoss Logging 3.x, and you have signed packages, you have to remove all vestiges of JBoss Logging 2.x which include jboss-logging-spi.jar, jboss-logging-log4j.jar, and jboss-logging-jul.jar.  But be aware that you may run into other problems, especially if your logging configuration references classes which were present in JBoss Logging 2.x.  Using JBoss Logging 3.x is not exactly supported on JBoss AS 5.x but you can give it a shot.
