we try to install and run a protege server but get several exceptions we
cannot explain. This is the first part of the console log:

Protege server is starting...
Protege 3.4.7 Build 620, JVM 1.6.0_22-b22, memory=954M, Linux,
encoding=UTF-8, language=de, country=DE
Server port = 5200, registry port = 1099, compressed stream
Using metaproject from: file:/home/iop/serverconfig.pprj
Loading project Test from file:/home/iop/test.pprj
Loading project plugins for project Test
SEVERE: java.rmi.ServerException: RemoteException occurred in server
thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested
exception is:
java.lang.ClassNotFoundException: access to class loader denied
at sun.rmi.server.UnicastServerRef.oldDispatch(
at sun.rmi.server.UnicastServerRef.dispatch(
at sun.rmi.transport.Transport$
at Method)
at sun.rmi.transport.Transport.serviceCall(

followed by many similar exceptions and ending with:

... 12 more
Caused by: access denied
( /opt/Protege_3.4.7/- read)
at java.lang.SecurityManager.checkPermission(
at sun.rmi.server.LoaderHandler$Loader.access$000(
at sun.rmi.server.LoaderHandler.loadClass(
... 21 more

we currently have no clue what is going wrong... someone an idea?

best regards
