[drools-user] Permissions problem in WebSphere

[Steven Williams]

Hi all,
We are using WebSphere 6.1 with java security switched on and get the following error when we attempt to run drools:


Permission:

      \D:\WS_STAGE2\ec_ejb\bin\au\gov\vic\dse\lx\ec\Message.class : Access denied ( java.io.FilePermission \D:\WS_STAGE2\ec_ejb\bin\au\gov\vic\dse\lx\ec\Message.class read)

Code:

     org.drools.base.au.gov.vic.dse.lx.ec.Message$getStatus  in  {null code URL}

Stack Trace:

It looks to me like the drools generated Message class (org.drools.base.au.gov.vic.dse.lx.ec.Message) is failing when it attempts to access the application Message.class via its getStatus method. We have added java.security.AllPermission everywhere we can think of (was.policy, app.policy, library.policy, server.policy) and it still does not work.

 

Has anybody got drools working in a WebSphere environment (any version) with java security turned on?

 

I noticed that there used to be a problem with cglib where the generated classes did not get the same protection domain as the cglib.jar (http://jira.atlassian.com/browse/CONF-5955 , http://forum.hibernate.org/viewtopic.php?p=2190363). I know we are using ASM but maybe it also has a similar problem?

 

thanks

Steve
