help finding a weblogic class weblogic/xml/crypto/wss/provider/CredentialProvider

we have created a webservices client that works in jdeveloper.  However, when I try and run it on our linux production server I get a  class path not found for weblogic/xml/crypto/wss/provider/CredentialProvider.  We have installed java 1.7 on the server.  jdev 11.1.2 on our PCs.

This is a excerpt from the error that is generated:

[Loaded java.lang.Throwable$WrappedPrintStream from /app/oracle/java/jre/lib/rt.jar]

[Loaded java.util.IdentityHashMap from /app/oracle/java/jre/lib/rt.jar]

java.lang.NoClassDefFoundError: weblogic/xml/crypto/wss/provider/CredentialProvider
