1. Re: java.lang.LinkageError: loader constraints violated when
daviskv Oct 26, 2005 12:20 AM (in response to daviskv)To give more info on this problem - actually, the jar (sfcUtil.jar) contains this Response class is there in both EAR and WAR file. But when removing the jar from WAR and keeping only in EAR, failing to deploy the application fully.
Could you please direct me some packaging doc with regards to this problem ?.
Thanks in advance.

amit.bhayani Oct 26, 2005 4:53 AM (in response to daviskv)From 4.0.2 JBoss has changed to the Servlet spec classloading model, i.e. it uses the Tomcat classloader.
Try setting UseJBossWebLoader to true in jboss-4.x.x\server\XXX\deploy\jbossweb-tomcat50.sar\jboss-service.xml

daviskv Oct 26, 2005 5:54 AM (in response to daviskv)Hi Amit,
We have tried your suggession making the UseJBossWebloader property to true, but this time both the cases not able to fully deploy the application. Meaning, case 1. placing the sfcutil.jar file in EAR alone
Case 2. Placing sfcUtil.jar file in both EAR and WAR files.
The deployer is stuck where its trying to load a particular Servlet as shown in the below console messages. The bold part is actually coming when specifying the UseJBossWebloader property to false in the case 2, but getting the linkageError as posted earlier.
