Hello Terri,
Castor generates these *Descriptor classes at runtime but they can be
generated at compile time and shipped with the application. In this case you
can sign the generated classes and should be rid of this problem.

Hi,
I'm running into problems trying to use castor's xml mapping in an applet.
Is anyone else doing this?
The first issue I encountered was that castor depends on commons-logging
and commons-logging-1.1 causes an AccessControlException unless the jar is
signed. It seemed that I continued getting the same AccessControlException
unless I also signed castor.jar. With those hurdles out of the way, I'm
now getting the exception shown below.
Note that CmdParam is the class I'm unmarshaling; CmdParamDescriptor is
*not* one of my classes; I guess it's generated by castor on the fly, which
would explain why it hasn't been signed. I'm using castor's default
unmarshaling (no mapping file, no compile time descriptors). I imagine that
I might be able to get past this problem by using compile time descriptors,
but I'd like to know whether others have had success using castor's xml
marshaling/unmarshaling in an applet.
Thanks,
Terri
p.s. I'm also curious whether castor really is creating the
CmdParamDescriptor class at runtime, or if I'm misinterpreting things. I
hope that someone who's more familiar with the way castor works than I am
can tell me.
