Problem with Tomcat's security manager and DataSource in struts-config.xml

[stephen.chambers]

All,

I have been migrating a smaller Tomcat/MySQL application to Struts and have run into a 
problem.

I have completely converted the app to Struts and hit a snag when I inserted the 
DataSource tag into the struts-config.xml. It began to generate "Cannot fond 
ActionMappings" errors in the html and in the logs could not find the database, asking 
"Is there a MySQL database running on this server?"

My Tomcat 4.0 (on RH 7.1) is running with security and I added these lines to the 
conf/catalina.policy file, each on as nothing else seemed to work:

grant CodeBase "file:${catalina.home}/webapps/myapp/-" {
        permission java.security.AllPermission;
        };
grant CodeBase "file:${catalina.home}/webapps/myapp/-" {
        permission java.security.AllPermission;
        };
