The Oracle docs note this on the ora-29532 error:

ORA-29532: Java call terminated by uncaught Java exception: string

Cause: A Java exception or error was signaled and could not be resolved by the Java code.

Action: Modify Java code, if this behavior is not intended.
Oracle MetaLink Documents offer descriptions of problems regarding ORA-29532. They outline these error possibilities and resolutions by showing three examples. Perhaps one of these examples is similar to your problem with ORA-29532:

followed by a detailed error message similar to one of the following messages:

-----------
Example # 1
-----------

java.security.AccessControlException: the Permission

(java.net.SocketPermission hostname resolve)

SchemaProtectionDomain(SCOTT|PolicyTableProxy(SCOTT))

-----------
Example # 2
-----------

java.security.AccessControlException: the Permission

(java.util.PropertyPermission * read,write)
