Hello All, I have exposed an SLSB as an web-service. There is no transaction on this SLSB which i have implemented. But this SLSB makes calls to Springs Beans on which transaction has been implemented. I am getting the below error and i am not able to find a reason for this. I am using Jboss-4.0.3-SP1 and JDK142. Can someone give me some pointer. Thanks in advance, Subramaniam V | java.rmi.ServerException: EJBException:; nested exception is: | javax.ejb.EJBException: Transaction not allowed | at org.jboss.ejb.plugins.LogInterceptor.handleException(LogInterceptor.java:352) | at org.jboss.ejb.plugins.LogInterceptor.invokeHome(LogInterceptor.java:125) | at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invokeHome(ProxyFactoryFinderInterceptor.java:93) | at org.jboss.ejb.SessionContainer.internalInvokeHome(SessionContainer.java:613) | at org.jboss.ejb.Container.invoke(Container.java:894) | at sun.reflect.GeneratedMethodAccessor148.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:324) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:141) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:80) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:72) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:245) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:644) | at org.jboss.invocation.local.LocalInvoker$MBeanServerAction.invoke(LocalInvoker.java:155) | at org.jboss.invocation.local.LocalInvoker.invoke(LocalInvoker.java:104) | at org.jboss.invocation.InvokerInterceptor.invokeLocal(InvokerInterceptor.java:179) | at org.jboss.invocation.InvokerInterceptor.invoke(InvokerInterceptor.java:165) | at org.jboss.proxy.TransactionInterceptor.invoke(TransactionInterceptor.java:46) | at org.jboss.proxy.SecurityInterceptor.invoke(SecurityInterceptor.java:55) | at org.jboss.proxy.ejb.HomeInterceptor.invoke(HomeInterceptor.java:169) | at org.jboss.proxy.ClientContainer.invoke(ClientContainer.java:86) | at $Proxy98.create(Unknown Source) | at sun.reflect.GeneratedMethodAccessor322.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:324) | at org.jboss.net.axis.server.EJBProvider.makeNewServiceObject(EJBProvider.java:140) | at org.jboss.axis.providers.java.JavaProvider.getNewServiceObject(JavaProvider.java:280) | at org.jboss.axis.providers.java.JavaProvider.getServiceObject(JavaProvider.java:131) | at org.jboss.axis.providers.java.JavaProvider.invoke(JavaProvider.java:335) | at org.jboss.axis.strategies.InvocationStrategy.visit(InvocationStrategy.java:73) | at org.jboss.axis.SimpleChain.doVisiting(SimpleChain.java:160) | at org.jboss.axis.SimpleChain.invoke(SimpleChain.java:123) | at org.jboss.axis.handlers.soap.SOAPService.invoke(SOAPService.java:560) | at org.jboss.axis.server.AxisServer.invoke(AxisServer.java:355) | at org.jboss.axis.transport.http.AxisServlet.doPost(AxisServlet.java:911) | at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) | at org.jboss.axis.transport.http.AxisServletBase.service(AxisServletBase.java:370) | at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) | at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) | at org.jboss.web.tomcat.security.CustomPrincipalValve.invoke(CustomPrincipalValve.java:39) | at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:159) | at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:482) | at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:59) | at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) | at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) | at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) | at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) | at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:856) | at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:744) | at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) | at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) | at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) | at java.lang.Thread.run(Thread.java:534) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4069148#...
