hi, I've ever deploy my app on jbossas 5 and it works well. but when today I just want to use jbossas 4.2.0 since it is GA version, it crashed. here is the message: javax.servlet.ServletException: org.apache.hivemind.ApplicationRuntimeException: Unable to construct service tapestry.request.DisableCachingFilter: Error building service tapestry.request.DisableCachingFilter: Failure invoking constructor for class org.apache.tapestry.services.impl.DisableCachingFilter: edu/emory/mathcs/backport/java/util/concurrent/locks/ReentrantLock [jar:file:/D:/server/jboss- 4.2.0.GA/server/default/lib/tapestry-framework-4.1.1.jar!/META-INF/tapestry.request.xml, line 238, column 20] org.apache.tapestry.services.impl.WebRequestServicerPipelineBridge.service( WebRequestServicerPipelineBridge.java:65) $ServletRequestServicer_112a21e8bb3.service($ServletRequestServicer_112a21e8bb3.java) could any one tell me why and how to resolve this? thank you!
