Tomcat security issue with jdbc connections
This is a reminder for me, for Tomcat setting about security violation.
In a simple servlet, if you have some issue with db connection, with this output:
java.security.AccessControlException: access denied (java.net.SocketPermission localhost resolve)have a look at Tomcat security policy.
To correct this problem, you have to edit /etc/tomcat5/policy.d/
We want to give all contexts not configured by their own grant entry some default permissions in addition to what Tomcat assigns by default:
grant {
permission java.net.SocketPermission "localhost:3306","listen,connect,resolve";
permission java.util.PropertyPermission "*","read";
};You may have to replace localhost:3306 with your db host and port.
