Applet inside WAR

I packaged an applet inside a WAR with a bunch of JSP files. when I load the applet outside that WAR it closes perfectly, however in the WAR this doesn't happen.

Is there anything I haven't done yet. Some kind of file to include?.

PD: I'm using signed jars, and also JNLP implementati开发者_Go百科on to load the applet and it resources. So, that's not the problem

Thanks in advance.
