Struts2 Tomcat deployment permission problems

Deploy it in tomcat5.5. Start the server. The error message is:

 

Caught exception while loading file struts-default.xml-class: Java. Security. accesscontrolcontext
File: accesscontrolcontext. Java
Method: checkpermission
Line: 264-Java/security/accesscontrolcontext. Java: 264:-1

...... ......

......

Caused by: Java. Security. accesscontrolexception: Access Denied (Java. Io. filepermission file:/E:/host/002/devbar.org/root/web-inf/lib/struts2-core-2.0.11.jar! Struts-default.xml read)

 

Add the following content to the comf/Catalina. Policy file under Tomcat:

Grant codebase "file :$ {Catalina. Home}/root //-"{
Permission java. Security. allpermission;
};

In addition, it is possible that all jar packages of struts2 are not put into the application.

Or, it seems that two struts2 projects under the same application also have this problem?
