fuseWeblogicBEAconnection

An example on how to connect to weblogic BEA with camel Jms component on Jboss Fuse.

The main issue to overcome in order to have a jms BEA connector deployed in Jboss fuse is about OSGi compliance of Weblogic JMS driver, basically what has been described in:

• https://issues.jboss.org/browse/ENTESB-1567
• https://issues.jboss.org/browse/ENTESB-3699

Solution/Workaround

The solution is based on:

• Force the weblogic driver to use the correct classloader by using the com.github.valdar.jndi.JndiFactoryFactory class to instantiate the Weblogic Jms connection factory:

<bean id="factory" class="com.github.valdar.jndi.JndiFactoryFactory"/>
<bean id="webLogicJmsConnectionFactory" factory-ref="factory" factory-method="createJndiObjectFactory" init-method="afterPropertiesSet">
    <property name="jndiTemplate" ref="jndiWebLogicTemplate"/>
    <property name="jndiName" value="WWPConnectionFactory"/>
    <property name="proxyInterface" value="javax.jms.ConnectionFactory"/>
</bean>

• Be sure that weblogic wrapped bundle doesn't export javax.* package by:

osgi:install wrap:file://<projecthome>/wlthint3client.jar,file://wlthint3client.bnd/wlthint3client.bnd

this is done with the setting in wlthint3client.bnd.

Doing the same in a fabric profile

From Fuse 6.3 Roll up patch 1, you can achieve the same directly in a profile; to add the wrapped wlthint3client.jar in a profile just add in io.fabric8.agent.properties something on the lien of:

...
bundle.wlthint3client = fabric:wrap:mvn:com.oracle/wlthint3client/12.1.3$Import-Package=javax.ejb;resolution:=optional,javax.ejb.spi;resolution:=optional,javax.jms;resolution:=optional,javax.transaction;resolution:=optional,javax.transaction.xa;resolution:=optional,javax.xml.stream;resolution:=optional,*;resolution:=optional&Export-Package=!javax.ejb,!javax.ejb.spi,!javax.jms,!javax.transaction,!javax.transaction.xa,!javax.xml.stream,*
...

Build instructions

1. To build this project be sure to have maven 3.x installed and from the directory run: mvn clean package
2. Download from Oracle the wlthint3client.jar jar.
3. To deploy the example to JBoss Fuse 6.2.1 container. You will run the following command from karaf shell:

features:install activemq-camel
osgi:install wrap:file://<projecthome>/wlthint3client.jar,file://<projecthome>/wlthint3client.bnd
osgi:install -s file://<projecthome>/target/fuseWeblogicBEAconnection-1.0.0-SNAPSHOT.jar
