2. Re: Seam component instantiation problem
klsateesh Jul 31, 2006 1:58 PM (in response to bluetrade)Hi,
I am also having an issue with the Instantiation of the Seam Component..
I am trying the HelloWorld App in examples/remoting..
In the JBoss Server log i see the component..13:43:42,828 INFO [Scanner] scanning: /D:/Projects/DPA/Jboss4.0.4/server/default/tmp/deploy/tmp43419MySeamTest.ear-cont ents/MySeamTest-ejb.jar 13:43:42,828 INFO [Component] Component: helloAction, scope: STATELESS, type: STATELESS_SESSION_BEAN, class: org.jboss. seam.example.remoting.HelloAction, JNDI: MySeamTest-war/HelloAction/local 13:43:42,984 INFO [Initialization] done initializing Seam
Note: i have created an EAR App (MySeamtest) in NetBeans and hence the name MySeamTest.ear..
And when i run the App it is accepting the User Name and the throwing the following Exception..13:43:58,429 ERROR [ExecutionHandler] Error during remote request org.jboss.seam.InstantiationException: Could not instantiate Seam component: helloAction at org.jboss.seam.Component.newInstance(Component.java:735) at org.jboss.seam.Component.newInstance(Component.java:1308) at org.jboss.seam.Component.getInstance(Component.java:1263) at org.jboss.seam.Component.getInstance(Component.java:1246) at org.jboss.seam.remoting.Call.execute(Call.java:101) at org.jboss.seam.remoting.ExecutionHandler.handle(ExecutionHandler.java:92) at org.jboss.seam.remoting.SeamRemotingServlet.doPost(SeamRemotingServlet.java:56) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) 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:96) 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.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) 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:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java :664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Thread.java:595) Caused by: javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.LocalOnlyContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.LocalOnlyContextFactory] at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:657) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:247) at javax.naming.InitialContext.init(InitialContext.java:223) at javax.naming.InitialContext.<init>(InitialContext.java:197) at org.jboss.seam.util.Naming.getInitialContext(Naming.java:28) at org.jboss.seam.util.Naming.getInitialContext(Naming.java:37) at org.jboss.seam.Component.instantiate(Component.java:774) at org.jboss.seam.Component.newInstance(Component.java:731) ... 26 more Caused by: java.lang.ClassNotFoundException: org.jnp.interfaces.LocalOnlyContextFactory at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1352) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1198) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:242) at com.sun.naming.internal.VersionHelper12.loadClass(VersionHelper12.java:42) at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:654) ... 33 more

klsateesh Jul 31, 2006 2:08 PM (in response to bluetrade)Hi,
It seems the name should be MySeamTest/HelloAction/local instead of MySeamTest-war/HelloAction/local .
I made the change and still getting the error..!!"klsateesh" wrote:

4. Re: Seam component instantiation problem
klsateesh Jul 31, 2006 2:18 PM (in response to bluetrade)Hi All,
I Checked the JNDI MBean View and i see an entry for Hello Action..Global JNDI Namespace +- XAConnectionFactory (class: org.jboss.mq.SpyXAConnectionFactory) +- MySeamTest (class: org.jnp.interfaces.NamingContext) | +- HelloAction (class: org.jnp.interfaces.NamingContext) | | +- local (proxy: $Proxy182 implements interface org.jboss.seam.example.remoting.HelloLocal,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject) +- TopicConnectionFactory (class: org.jboss.naming.LinkRefPair)
pls let me know how to resolve this..
Thanks

Thanks for your reply..
I have included the jboss-ejb3-all.jar in the CLASSPATH and when i try to run the example i am getting the below Exception.
I have searched the forum for this and it seems a ClassLoading Issue and a JBoss bug .Not sure whether it is resolved or not..Could u pls let us know..10:31:24,805 ERROR [ExecutionHandler] Error during remote request java.lang.IllegalArgumentException: value found for In attribute has the wrong type: helloAction at org.jboss.seam.Component.getInstance(Component.java:1273) at org.jboss.seam.Component.getInstance(Component.java:1246) at org.jboss.seam.remoting.Call.execute(Call.java:101) at org.jboss.seam.remoting.ExecutionHandler.handle(ExecutionHandler.java:92) at org.jboss.seam.remoting.SeamRemotingServlet.doPost(SeamRemotingServlet.java:56) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) 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:96) 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.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) 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:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java :664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Thread.java:595)

7. Re: Seam component instantiation problem
gavin.king Aug 1, 2006 1:10 PM (in response to bluetrade)Use your debugger to resolve the problem. I very much doubt that this is due to any bug in JBoss.
