Hi Harald,

You might want to have a look at the Cheiron Utils project that provides
a class that can wrap your JavaSpace05 proxy that will set/restore the
proper thread context class loader and security context (if this is
relevant to you), see
http://www.cheiron.org/utils/release/v0.2/api/org/cheiron/util/proxy/ProxyWrapper.html

In your case you have to do something like this

   JavaSpace05 space = <obtain your JavaSpace proxy>;
   space = (JavaSpace05) ProxyWrapper.wrap(space, null, loader);

Where null indicates the current security context to be used and loader
the context class loader you want to have effective upon invocations.
This class has been written to correct 'wrong' environments as present
in many application servers (especially in the past) and the AWT event
queue.
