Maven adding source control to ClearCase

On my recent work, there's a requirement of having Maven to build an J2EE EAR file and then checkin the EAR to ClearCase. Maven SCM plugin has the ClearCase plugin, however, the scm:add command doesn't work for ClearCase. The problem got work around by executing Ant's ClearCase task in Maven.

Adding a source control to ClearCase involves three steps;
1 - Check out the containing folder of the new source file.
Acomplished by Ant task:
<cccheckout viewpath="c:/ci/view/my_view/MyFolder">

2 - Invoke the Clear Case mkelem command.
Acomplished by Ant task:
<ccmkelem viewpath="c:/ci/view/my_view/MyFolder/test4.ear" checkin="true" comment="Initial checkin">
</ccmkelem>

3 - Chech in the containing folder
Acomplished by Ant task:
<cccheckin viewpath="c:/ci/view/my_view/MyFolder" identical="true">

EJB Interoperability of JBoss Portal and IBM WAS

This posting outlined how we configured the servers to have a Portlet which runs in JBoss Portal making EJB calls to WAS. This involves couple of challenges:

- Interoperability between IBM and Non IBM components on JNDI binding and EJB calls.
- Compatibility of different JDK versions among Portal and Middle tier.
- The situation of having JDK 1.5 running JBossPortal and JDK 1.4 running WAS.

1. Preparing JBoss Portal for WAS EJB interoperability

- Install IBM JDK 5, run JBossPortal using IBM JDK. IBM packaged their low level CORBA//IIOP classes in their JDK runtime, using standard Sun's JDK5 results to a lot of Class Not Found Exception.

- Copy jacorb.jar from $JBOSS_HOME\client to $JBOSS_HOME\server\default\lib
- Copy jboss-iiop-client.jar from $JBOSS_HOME\client to $JBOSS_HOME\server\default\lib


2. Packing Portlet application for WAS EJB Client

The following IBM jars are required to package into the WEB-INF\lib directory of the Portlet's WAR.

- naming.jar
- naminglcient.jar
- wsexception.jar
- iwsorb.jar
- ras.jar
- bootstrap.jar
- emf.jar
- ecutils.jar
- ffdc.jar
- idl.jar
