The code that makes that call is > ognl.OgnlRuntime.invokeMethod(OgnlRuntime.java:834) That is not Tomcat code. You should ask the authors of that OGNL library (and check whether you use the latest version of it). They are making that call with wrong arguments. The rest is from my general knowledge. Usually the calls to "checkPermission()" are performed only when you run with Java's SecurityManager being enabled. Try to enable it when you are running at home and see whether the error reproduces itself. (Or try to disable it in your production configuration and see how the error goes away). http://tomcat.apache.org/tomcat-6.0-doc/security-manager-howto.html Best regards, Konstantin Kolinko --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
