im a developing an application that is based on an applet that gets the data of a postgresql DB using hibernate, everything is ok when i see it by eclipse, but im gettin some problems when deployiong it on tomcat 5.5.9
i already include jars that the applet needs, the problem seems that i have to grant permission to the applet to connect and get info of the db, i test by modifying my java.policy and it works well the web page, but obviusly this only wokrs locally (it would work on other clients only if the clients modifies its own java.policy) so thats not a razonable solution.
the other solution i read was to make it a signed applet, i did it but still the same error...
