Subject Re: Implementing Global JNDI
Date Wed, 28 Jun 2006 07:17:14 GMT
Hi,

We have created  a JIRA
(http://issues.apache.org/jira/browse/GERONIMO-2153  ) and attached
the initial draft. We have tried two approaches.

* Adding to plan
* Deploying from Builder.

The EJBJNDIBindingGBean deploys from OpenEJBModuleBuilder and has a tag
  <global-jndi/> in opene ejb plan.

Resource Adapter and GBean have a gbean plan added to deployment plan.

<gbean name="JMSQueueFactoryJNDIBindingGBean"
class="org.apache.geronimo.connector.jndi.ConnectorJNDIBindingGBean">
<attribute name="configId">test/jms.rar/1.0/rar</attribute>
<attribute name="jndiName">globalJMSQueueFactory</attribute>
<attribute name="componentName">JMSQueueFactory</attribute>
<attribute name="j2eeType">JCAManagedConnectionFactory</attribute>
<attribute name="interfaceName">org.apache.geronimo.jms.connector.JMSQueueConnectionFactory</attribute>
</gbean>

and

<gbean name="TestGBeanJNDIBindingGBean"
class="org.apache.geronimo.service.jndi.ServiceJNDIBindingGBean">
<attribute name="configId">test/gbean/1.0/car</attribute>
<attribute name="jndiName">globalTestGBean</attribute>
<attribute name="componentName">TestGBean</attribute>
<attribute name="j2eeType">GBean</attribute>
<attribute name="className">gbean.test.TestGBean</attribute>
</gbean>

We have a Classloading issue when trying to maintain all the
BindingGbeans at one level. ( rmi-naming ). For GBeans and Resource
Adapters that are not J2EE interfaces like javax.sql.DataSource /
javax.jms.QueueConnectionFactory we get a ClassNotFound as the class
is not available at Classloader of rmi-naming.

We spent a lot of time trying to solve this issue but are not able to
find a solution as the application level interface or class is not
available. This problem will not occur for j2ee interfaces like
DataSource, EJB interfaces, Queue, Topic etc..

If the approach is correct we would like to add the other features to
make this more suitable for adding into the product.

Krishnakumar B
