[JBoss-user] 3.2.1 No ClassNotFound for datasource missing required jar

[Guy R. <guy...@sp...>]

We are still running 2.4.3 at work, and I'm starting to prepare for the 
transition to 3.2.x.  In my first test conversion, I created an Oracle 
datasource and deployed it.  I forgot to copy classes12.jar into 
server\<myserver>\lib.  But looking through the boot.log and server.log, 
I can find no message informing me that it could not find class 
oracle.jdbc.driver.OracleDriver.  Instead, when I attempted to deploy an 
EJB which uses this datasource, I got the following messages:

2003-05-23 17:27:18,682 DEBUG [org.jboss.ejb.StatelessSessionContainer] 
Begin java:comp/env for EJB: com.masergy.ejb.OrderManagement.OrderManagement
2003-05-23 17:27:18,682 DEBUG [org.jboss.ejb.StatelessSessionContainer] 
TCL: java.net.URLClassLoader@72da21
2003-05-23 17:27:18,772 ERROR [org.jboss.ejb.StatelessSessionContainer] 
Starting failed
javax.naming.NameNotFoundException: comp not bound
	at org.jnp.server.NamingServer.getBinding(NamingServer.java:495)

Needless to say, this message is not very helpful.  I eventually figured 
out my setup problem and was then able to deploy the EJB.  (As a side 
note, the only change I had to make to deploy my EJB from 2.4.3 was to 
add the doctype to ejb-jar.xml.  Great job, JBoss authors!)  Why didn't 
I get a ClassNotFound exception when the Oracle datasource was deployed?
