Examining the source of the GeoTools class it seems that there is no possibility to avoid the security exceptions in an unsigned applet.
Using an unsigned applet offers a possibility. Signing the applet jar is not enough, you have to sign gt-metadata.jar and the gt-reference.jar. (the gt-metadata.jar is responsible for these exceptions). Perhaps we should document this trap in the wiki ????
