I am using an applet in a jsp application. There is a save button in the applet, when i hit the save button, control should return back to the jsp application. However this is not happening.
Since i am using applet,it seems that it cannot use the system resources. so i need to set the policy file.i hope i am interpreting the problem correct.Can anyone please guide me the procedure to give the permission in the policy file.

Thanks in advance

you need to sign your jar file

in steps
i got it from javaCook book

Recipe 23.14 Signing Your JAR File

1-Create a new key in a new "keystore" as follows:
keytool -genkey -keystore myKeystore -alias myself

The program prompts you in the terminal window for information about the new key

2-Create a self-signed test certificate:
keytool -selfcert -alias myself -keystore myKeystore

You enter the keystore password and keytool generates the certificate.

3-You can now sign the JAR file with your test certificate:

jarsigner -keystore myKeystore test.jar myself

What do you mean by "control should return back to the jsp application"? Does the applet submit an HTTP request, and afterwards you want to redirect to a certain JSP page? If so, you can do that using getAppletContext().showDocument(String).
I agree. Here's the link: http://aspose.com/file-tools
