[esb-issues] [JBoss JIRA] Closed: (JBESB-1951) Unable to use JCA Gateway with custom jcaBridge

Unable to use JCA Gateway with custom jcaBridge ------------------------------------------------ Key: JBESB-1951 URL: https://jira.jboss.org/jira/browse/JBESB-1951 Project: JBoss ESB Issue Type: Bug Security Level: Public(Everyone can see) Components: Adapters Affects Versions: 4.3 Environment: Windows XP, jdk 1.5.0_15, JBoss AS 4.2.2 Reporter: Peter Mischke Assignee: Kevin Conner Fix For: 4.4 CP2, 4.5 I'm using the following JCA gateway configuration: <jca-gateway name="SOAP-Gateway" endpointClass="com.example.SOAPGateway" transacted="false" jcaBridge="com.example.SomeBridge" adapter="soapadapter-1.0-SNAPSHOT.rar"> <activation-config> <property name="someName" value="someValue" /> </activation-config> </jca-gateway> The important parameter in this example is: jcaBridge="com.example.SomeBridge" During start-up of the ESB module, I get the following exception: Caused by: org.jboss.soa.esb.listeners.lifecycle.ManagedLifecycleException: Unexpected exception while instantiating managed instance at org.jboss.soa.esb.listeners.LifecycleUtil.getManagedInstances(LifecycleUtil.java:158) at org.jboss.soa.esb.listeners.LifecycleUtil.getGateways(LifecycleUtil.java:103) at org.jboss.soa.esb.listeners.config.Configuration.create(Configuration.java:113) ... 46 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494) at org.jboss.soa.esb.listeners.LifecycleUtil.getManagedInstances(LifecycleUtil.java:154) ... 48 more Caused by: org.jboss.soa.esb.ConfigurationException: Unable to load jcaBridge: com.example.SomeBridge at org.jboss.soa.esb.listeners.jca.BaseJcaInflow.<init>(BaseJcaInflow.java:110) at org.jboss.soa.esb.listeners.jca.JcaInflowGateway.<init>(JcaInflowGateway.java:44) ... 53 more Caused by: java.lang.NullPointerException at EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap.hash(ConcurrentReaderHashMap.java:298) at EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap.get(ConcurrentReaderHashMap.java:410) at org.jboss.mx.loading.UnifiedLoaderRepository3.getCachedClass(UnifiedLoaderRepository3.java:222) at org.jboss.mx.loading.RepositoryClassLoader.loadClass(RepositoryClassLoader.java:403) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at org.jboss.soa.esb.listeners.jca.BaseJcaInflow.<init>(BaseJcaInflow.java:106) ... 54 more Looking in the source code (latest version) of org.jboss.soa.esb.listeners.jca.BaseJcaInflow, I spot the following lines: String brdg = config.getAttribute(JcaConstants.ATTRIBUTE_JCA_BRIDGE); if (brdg != null) { try { bridge = (ActivationBridge) classLoader.loadClass(mt).newInstance(); } catch (Exception e) { throw new ConfigurationException("Unable to load jcaBridge: " + brdg, e); } } else { bridge = new JBoss42ActivationBridge(); } I suppose, the JCA gateway tries to instantiate the wrong class.
