 &nbsp;You need to alter your policy file (java.policy) and give SocketPermission to localhost on port 1313 for listen and resolve. You have to do something like the following:<br />
<br />
grant {<br />
&nbsp; &nbsp; permission java.net.SocketPermission &quot;loclhost:1313&quot;, &quot;listen,resolve&quot;;<br />
};

Ok, thanks. Where should I put this file? Or where do I find it?

Great, I assume both applet and servlet need re-compiling under the new policy before uploading.

 &nbsp;Thank you :-)<br />

&nbsp; No, recompilation is not needed. However you will need to restart your server in order for the servlets to be able to use the new policy file. Note that Tomcat might have its own policy file so you might need to change that one as well :-)

I have a servlet/applet rmi communication example which gives me this messages:<br />
<br />
Problem establishing server socket: java.security.AccessContro<wbr />lException<wbr />: access denied (java.net.SocketPermission<wbr /> localhost:1313 listen,resolve)<br />
<br />
It seems I need to set a security manager somewhere, but I'm having trouble finding out where and how exactly what I need to do to grant the socket permission.

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
