Hi Folks,

I am trying to connect to a SAP system via SAPs JavaConnector (JCo). Some calls to the methods in JCo classes are running correctly, others throw a AccessControlException:

My environment:

Domino 6.5.2 on SuSE Linux 9.1 Prof. or Domino 6.5.2 on AIX 5.2

Accessing my database with an action in a HTML page, which calls a LotusScript agent. The LS agent again calls a Java agent with calls to the SAP JCo Java lib.

SAP JCo lib is in Dominoroot/jvm/lib/ext which has “AllPermissions” in Dominoroot/jvm/bin/lib/security/java.policy.

Any suggestions?

Johann,

You may just need to change the agent properties security (key) tab to # 3 – “Allow restricted operations with full administration rights.”
