Java Policy changes needed for Jabaco Applets?

Hi Manuel,

my first test applet with Jabaco ran fine in the applet viewer.

But due to security failures I could not get it started within my Internet Explorer.

I am using Java JRE 6.07. Google Chrome and Firefox had the same problem. Safari works OK.

My solution is to extend the Java policy file (cf. attachment). Now it works correctly.

On my system the file is

C:\Programme\Java\jre6\lib\security\java.policy

It would be nice to get around this problem. We can hardly alter the policy files of all potential users.

Best regards!

Signed Applets don't require policy changes

Hi Manuel,

OK! I've found it myself by reading some of the other posts.

As soon as I "sign" the applet with "jarsigner" (using a key generated with "keytool") and replace the original jar file with the signed one, it will start without problems. The user gets the choice to trust the signed jar file.

Regards,
