Hi, in Ubuntu 8.0.4 I installed Eclipse and I used OpenJdk to compile my program described here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=484273 If I make java-jar MyRecipes.jar on the shell, it works perfectly. But if I click the mouse right on jar files and select "open with OpenJdk Runtime" the program does not work. . Why? thanks for any answers. Regards
