ClassNotFoundException with moving to WAS 6.1
cald...@churchmutual.com
We have an iSeries system (I believe it is V5R4). We have WAS 5.0.2.18 installed on it with several apps. We recently installed WAS 6.1.0.7 on the same system and are in the process of migrating our apps over to run on it. The apps that we have inside of WAS run fine so far. We are having issues with our apps that run outside of WAS and attempt to make a connection to WAS to place messages on queues, etc.
We have an application called "propagation" which is one of these apps. We kick off the app using a QShell script, which is set up as follows for WAS 5.0:
../initEnvironment
/QIBM/ProdData/WebAS5/Base/bin/setupClient -instance $WASENVIRONMENT
export LIB_DIR=3rdparty
export COMPONENTS_DIR=lib
export COMPONENTS=$COMPONENTS_DIR/cmic-propagation-properties.jar:$COMPONENTS_DIR/cmic-propagation.jar:$COMPONENTS_DIR/rulesengine-dummy.jar:$COMPONENTS_DIR/cmic-base.jar:$COMPONENTS_DIR/systemx.jar:$COMPONENTS_DIR/messaging.jar:$COMPONENTS_DIR/systemx-server-tools.jar:$COMPONENTS_DIR/cmic-persistence.jar:$COMPONENTS_DIR/cmic-database.jar

export CP=$COMPONENTS:$LIST1:$LIST2
java $JAVA_FLAGS_EXT -classpath $CP com.churchmutual.project6.propagation.automation.VersionQuestions
We realized that we needed to call a different setupClient for WAS 6.1, so after a little searching we found it an modified our shell script to look like the following:
../initEnvironment
/QIBM/ProdData/WebSphere/AppServer/V61/Base/bin/setupClient -profileName $WASENVIRONMENT
export LIB_DIR=3rdparty
export COMPONENTS_DIR=lib
export COMPONENTS=$COMPONENTS_DIR/cmic-propagation-properties.jar:$COMPONENTS_DIR/cmic-propagation.jar:$COMPONENTS_DIR/rulesengine-dummy.jar:$COMPONENTS_DIR/cmic-base.jar:$COMPONENTS_DIR/systemx.jar:$COMPONENTS_DIR/messaging.jar:$COMPONENTS_DIR/systemx-server-tools.jar:$COMPONENTS_DIR/cmic-persistence.jar:$COMPONENTS_DIR/cmic-database.jar

export LIST2=$LIB_DIR/commons-collections.jar:$LIB_DIR/commons-dbcp.jar:$LIB_DIR/commons-pool.jar:$LIB_DIR/xercesImpl.jar:$LIB_DIR/cvslib_36.jar:$LIB_DIR/commons-logging-1.1-dev.jar
export CP=$COMPONENTS:$LIST1:$LIST2
java $JAVA_FLAGS_EXT -classpath $CP com.churchmutual.project6.propagation.automation.VersionQuestions
Now when we try to execute this script to kick off our code we can a ClassNotFoundException looking for com.ibm.websphere.naming.WsnInitialContextFactory.
Here's the stack trace:

I can see that class being set up in the setupClient script in the above directory and am not sure what is going on wrong here. We even tried manually dumping the jar that this class is in (om.ibm.ws.runtime_6.1.0.jar) and other needed jars into our 3rdparty lib directory and adding them to the classpath manually and that didn't work either. We are using JVM 1.5.0 to kick off the code. Any ideas on what to do here? What we are missing? The old script that runs under WAS 5.0 runs fine and locates the context factory. Why is this one not finding it? Any ideas would be greatly appreciated.
