Deploying EJB 3 and its DD elements

Guys,

Is the ejb-jar.xml a mandatory element for EJB 3.0 in Weblogic 10.3? I however want to use the weblogic-ejb-jar.xml just for optimizing my deployment and runtime behaviour of my beans. So When I tried this, I ran into Unmarshaller exception (during deployment) What could be the reason? Any suggestions?

According to ejb3 specifications, ejb-jar.xml is optional. Could you display error log message and the content of your ejb-jar file that you have created ?

Just to set this enable-call-by-reference to True I had to do this and when I deploy I run into the error above. How to get rid of this?

Verify if you're using a non-compliant type in your xsd. Maybe it's a xsd to java cast error made by STAXB

Didn't quite get you. I googled a little and found this,

http://forums.oracle.com/forums/thread.jspa?threadID=832889&tstart=-1

Afterwhich I changed my chema as below,

<weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/weblogic-ejb-jar" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/weblogic-ejb-jar/1.0/weblogic-ejb-jar.xsd http://www.bea.com/ns/weblogic/weblogic-ejb-jar/1.0/weblogic-ejb-jar.xsd">

But even after this, I keep getting this error like above!

Any solution guys? It is quite annoying that the Oracle website does not have enough information to support this!

Somehow I managed to get rid of the above one. Now I get into another kind of an exception,

Finally got rid of this error. The DD reference given in the Oracle website is wrong. Here is the correct one,

<weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/90" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/90
http://www.bea.com/ns/weblogic/90/weblogic-ejb-jar.xsd">

I used the 9.0 version but for the 10 version of Weblogic, simpley replace the 90 with 1.0 in the above schema.
 
It is sorta covered in the JavaRanch Style Guide.
