Hi,
I�ve seen this kind o error when I miss the xml element on the beginin of the dd files.
Chec if you have the tag:
<?xml version="1.0" encoding="UTF-8"?>
in all your dd�s also check if you have some missing tag.
Another point to consider is if you have edited the .xml files with some editor that corrupts the file, in last case try to build the .xml files again, this should help.
regards,
Marcos Maia.

I checked my ejb-jar and weblogic-ejb-jar files for missing tags. Every thing looks Ok, except, weblogic_sp.jar file in the lib directory is missing. Could this be the problem.
Thanks
Lal

The weblogic_sp.jar file will only be present if you have applied an incremental Service Pack to your WebLogic install. It is not the problem.
Post your deployment descriptor here and we might be able to help find the problem.

Looks like there an extra ? in the headers. You have:

<?xml version="1.0"? encoding="UTF-8"?>

Instead of:

<?xml version="1.0" encoding="UTF-8"?>

(Note the ? in the middle of your line!)
I think I've also seen errors like this if you have an XML comment which contains two dashes before the end of the comment:
<!-- -- --> (bad)
<!-- - - --> (good)

[Lalbahadur Bandaru]

I have made the changes Aaron has mentioned, to the dds, still I am getting the same error. There are no comments in my dds

Well, as a last resort for voodoo errors, you can try shutting down WebLogic, deleting all the temp files (there's a directory called tmp_... in your tree which you can delete, as well as any directories under .wlnotdelete named for you web apps), make 100% sure a version of the EAR or application content with the updated files is deployed, ensure WebLogic is running in development mode (there's an env veriable in the startup script), and then restart the server. That will make sure it's not just an old version of the DDs kicking around somewhere.
