Hello, all
I know how to set the java policy file for a normal application through the java command.

My problem now is that I use it as a bean inside a JSP page.

How I set the policy file for the bean ?

I take a SecurityException because the bean tries to connect to a Socket.

The instantiation of the bean inside the JSP is like taht:
<jsp:useBean id="roomCoordinator" class="com.game.arena.RoomCoordinator" scope="application"/>


Any ideas ?

I found that inside the <apache>/conf/catalina.policy file the security restrictions are loaded.

I added at the end of the file the following lines:
grant{
    permission java.net.SocketPermission "*:1024-65535", "connect,accept,resolve";
};

but when I run the web page, again I took the AccessControlException: access denied......127.0.0.1:1099

I tried as well to add a codebase to the grant. I set the codebase to the class that tries the Naming.rebind (where the exception is thrown, the .jsp file and the parent class of the one that raises the exception (in other words the applet)

But none of them had any success.
It should be noted that I tried the previous things 1 at a time.

please help

I found that in catalina.bat file you couls enter arguments when the java command loads the server.

Unfortunately this do not work either.

The problem is solved.

After granting the permissions to the
<apache_home>/conf/catalina.policy file

the server MUT be started like this

<apache_home>/bin/catalina.bat start -security (windows)

Analogous for Linux
the key is the -security option
