Starting a 10.3.3 Weblogic domain raises NoClassDefFoundError

Question

Right now I'm facing some kind of strange problem with a Weblogic domain. When it starts, raises the following error right after starting it up. Guess it is related to classes conflict but... does anyone know which jar is responsible or how to evade this situation? I' ve been looking inside the weblogic 10.3.3 jars with no findings...

PS. Could this be related to a update from a previous version which had the EnumerationIterator implemented?

Thanks in advance.

PS. For the record, it is installed in a WinServer 2008

Answer 1

I cannot find weblogic/utils/collections/EnumerationIterator within my running domain or console app on 10.3.3.

But it does appear within 2 jar files in the Oracle/Middleware HOME directory, ie witin the Weblogic installation folders.

D:\Oracle\Middleware\modules\com.bea.core.utils.full_1.8.0.0.jar
D:\Oracle\Middleware\wlserver_10.3\server\lib\wlthint3client.jar

The first seems to be a common module used by all Middleware products including WL Server. And the second from the name wlthint3client might be what you're looking for - it's within the WL Server lib and your stacktrace refers to the internal t3 service
