As you suggested I will try with "trimspaces" and "javaencoding" options. Thanks a lot peter for your responses. PeterJ, I have yet another common issue as follows on PermGen space. I start my server and after a minute or two i get the following PermGen space issue. My application is very huge as such, I am struggling to resolve this issue. Is there any settings in JBOSS which will resolve this issue? Pls let me know on this if possible. 12:21:09,950 ERROR [LogInterceptor] Unexpected Error in method: public abstract com.unisys.trans.aircore.bkg.param.TicketingResponse com.unisys.trans.aircore.bkg.booketingejb.Booketing.retrieveOfficeProfileParameters(com.unisys.trans.aircore.utils.client.SecurityParam) throws com.unisys.trans.shared.util.response.SharedException,java.rmi.RemoteException java.lang.OutOfMemoryError: PermGen space 12:21:11,291 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception java.lang.OutOfMemoryError: PermGen space 12:21:12,633 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception java.lang.OutOfMemoryError: PermGen space 12:21:12,633 ERROR [[localhost]] Exception Processing ErrorPage[errorCode=500, location=/500error.jsp] 12:21:17,967 ERROR [Http11Processor] Error processing request java.lang.OutOfMemoryError: PermGen space Thanks and Regards, Darshan Parekh View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4198177#...
