i have a problem  in watching applets in browser. when i write  my applet  with sun one studio (j2sdk 1.4.0_02), in the tools->advanced java(sun) option "use java2 v1.1.4.0_02 for applet (require restart)" created and i can see my applet in browser easily. but when i change my IDE to JBuilder 2006 (jdk 1.5) my applets don't open in browser and i can't see any option like that option in browser.(i should to use jdk 1.4.2 or higher) what is the reason of this problem? and how can i recover that?
