WebLogic 11g and MQ 7.... when the game gets tough...

(see also a previous post...http://www.javamonamour.org/2010/08/weblogic-integration-with-mq-series.html)

I am following the instructions

http://ibswings.blogspot.com/2008/02/integrating-mq-broker-6-with-bea.html

and I get

I also get

which seems to be addressed here:

In this post it mentions some extra JARs for JNDI support, like mqcontext.jar....let's keep an eye on this.... this http://www-01.ibm.com/support/docview.wss?uid=swg24004684 is the support pack...


I target WLEventContextImpl and I find this:

===============================================
Found: WLEventContextImpl

Package: weblogic.jndi.internal
Library Name: wlthint3client.jar
Library Path: /Oracle/Middleware/wlserver_10.3/server/lib/wlthint3client.jar




I get the one in weblogic.jar, decompile the weblogic.jndi.internal.WLEventContextImpl class, and find that there is no debug statement in it.... I add some sysout in the lookup and copyObject methods to find out which class is causing the error, and copy the modified weblogic.jar back...

my patched class file is in /home/osb/workspacePVPreMaven/WLPatchForMQ/bin/weblogic/jndi/internal/WLEventContextImpl.class

I run these commands to copy the 3 jars in a temp directory and patch them:

cp /home/osb/workspacePVPreMaven/WLPatchForMQ/bin/weblogic/jndi/internal/WLEventContextImpl.class ./weblogic/jndi/internal/WLEventContextImpl.class

cp /Oracle/Middleware/wlserver_10.3/server/lib/weblogic.jar .
cp /Oracle/Middleware/wlserver_10.3/server/lib/wlfullclient.jar .
cp /Oracle/Middleware/wlserver_10.3/server/lib/wlthint3client.jar .
cp wlfullclient.jar wlfullclient.jar.ORI
cp weblogic.jar weblogic.jar.ORI
cp wlthint3client.jar wlthint3client.jar.ORI


jar uvf weblogic.jar weblogic/jndi/internal/WLEventContextImpl.class
cp weblogic.jar /Oracle/Middleware/wlserver_10.3/server/lib/weblogic.jar

jar uvf wlfullclient.jar weblogic/jndi/internal/WLEventContextImpl.class
cp wlfullclient.jar /Oracle/Middleware/wlserver_10.3/server/lib/wlfullclient.jar

jar uvf wlthint3client.jar weblogic/jndi/internal/WLEventContextImpl.class
cp wlthint3client.jar /Oracle/Middleware/wlserver_10.3/server/lib/wlthint3client.jar



and to restore the files:

cp weblogic.jar.ORI /Oracle/Middleware/wlserver_10.3/server/lib/weblogic.jar
cp wlfullclient.jar.ORI /Oracle/Middleware/wlserver_10.3/server/lib/wlfullclient.jar
cp wlthint3client.jar.ORI /Oracle/Middleware/wlserver_10.3/server/lib/wlthint3client.jar


Unfortunately the patch WORKS and traces the calls to JNDI lookups, but the decompilation must have messed it up because itcannot find a queue and the WLS crashes.

With some terror I discover that connector.jar delivered with MQ 7 dates back to 2001 (JDK 1.3) and providerutil.jar dates back to 2000 (JDK 1.2).

Enabling EJB, JMS, JNDI, ClassLoader flags doesn't help. Most likely the remote JMS destination deserialization fails.
