error in configuring soap adapter

Hai!

Iam working with rfc to webservice scenario.

In that while configuring the soap adapter, the following errors have occured.

SOAP: failed to sign the message due to java.security.PrivilegedActionException: com.sap.aii.af.security.impl.exception.MessageSecurityException: AccessControlException in Method: apply( Message, CPALookupObject ). The Code-Permission processing failed.

SOAP: error occured: com.sap.aii.messaging.srt.BubbleException: WS-Security privileged action exception [null "null"]; nested exception caused by: java.security.PrivilegedActionException: com.sap.aii.af.security.impl.exception.MessageSecurityException: AccessControlException in Method: apply( Message, CPALookupObject ). The Code-Permission processing failed.

Please! help me in sorting it out.

Regards,

Saritha.
