I want to connect to a mysql database at localhost:3306 using jdbc in
a GWT servlet, but when try connecting i get this error :
java.security.AccessControlException: access denied
(java.lang.RuntimePermission modifyThreadGroup)
...
I know that i need to apply a security policy for tomcat to solve this
proble, something like this :
grant codeBase "file:${catalina.home}/webapps/-" {
permission java.net.SocketPermissexactly where ion
"192.168.12.81:3306", "connect";
};
but I dont know I should apply this change ???
please explain solution for both hosted mode & web mode .
thanks
