Weblogic to JBoss migration

Steps > Code changes

• removed weblogic dependent code in JMS related code
• fixed some EJB violations. weblogic was lenient in not reporting these errors
• changed INITIAL_CONTEXT_FACTORY value to org.jnp.interfaces.NamingContextFactory. We made it a parameter so the code could work with both weblogic and Jboss
• made the datasource name a parameter (JBoss uses a value like java:/coolAppDataSource)
• made the user transaction name a parameter. weblogic uses javax.transaction.UserTransaction. JBoss uses just UserTransaction
• JBoss uses lookup URLs like jnp://10.1.3.246:1099 for a single node or jnp://10.1.3.246:1099,10.1.3.247:1099 for a cluster
• updated EJB xml files

Steps > Build changes

• changed build script to use these jars - jboss-j2ee.jar, javax.servlet.jar instead of weblogic jar. These jars are in client folder of JBoss installation.
• removed use of weblogic ejbc/appc utility in build script. JBoss does not require this step
