We've introduced reverse compatibility tests (AS5 client accessing 4.2.x server) and one of the problems I'm seeing is the client AS5 side missing the org.jnp.server.NamingServer_Stub class. It seem after jboss-naming was broken out we don't produce this class with RMIC anymore. Why is that? http://hudson.qa.jboss.com/hudson/view/JBoss%20AS/job/JBoss-AS-4.2.x-Comp... | javax.naming.CommunicationException: Could not obtain connection to any of these urls: localhost:1099 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is java.lang.ClassNotFoundException: org.jnp.server.NamingServer_Stub (no security manager: RMI class loader disabled)]] | at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1727) | at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:680) | at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:673) | at javax.naming.InitialContext.lookup(InitialContext.java:351) | at org.jboss.test.bmp.test.SmallCacheBmpUnitTestCase.testBMP(SmallCacheBmpUnitTestCase.java:46) | at junit.extensions.TestDecorator.basicRun(TestDecorator.java:22) | at junit.extensions.TestSetup$1.protect(TestSetup.java:19) | at junit.extensions.TestSetup.run(TestSetup.java:23) | at org.jboss.test.compatibility.test.matrix.MatrixTestContainer$TestProxy.run(MatrixTestContainer.java:185) | at org.jboss.test.compatibility.test.matrix.MatrixTestContainer$TestSuiteProxy.run(MatrixTestContainer.java:85) | Caused by: javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is java.lang.ClassNotFoundException: org.jnp.server.NamingServer_Stub (no security manager: RMI class loader disabled)] | at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:311) | at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1698) | ... 29 more | Caused by: java.lang.ClassNotFoundException: org.jnp.server.NamingServer_Stub (no security manager: RMI class loader disabled) | at sun.rmi.server.LoaderHandler.loadClass(LoaderHandler.java:371) | at sun.rmi.server.LoaderHandler.loadClass(LoaderHandler.java:165) | at java.rmi.server.RMIClassLoader$2.loadClass(RMIClassLoader.java:620) | at java.rmi.server.RMIClassLoader.loadClass(RMIClassLoader.java:247) | at sun.rmi.server.MarshalInputStream.resolveClass(MarshalInputStream.java:197) | at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1544) | at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1466) | at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1699) | at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1305) | at java.io.ObjectInputStream.readObject(ObjectInputStream.java:348) | at java.rmi.MarshalledObject.get(MarshalledObject.java:135) | at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:290) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4191016#...
