[esb-issues] [JBoss JIRA] Created: (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
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

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.
