I had just installed oracle 9i on my system and my system has jdk 1.4.2.After installation of oracle 9i my java programs compiled successfully but itdoesn't run.Is it possible that it is because oracle provides jre1.3 and my system has1.4.Can anybody help me how to make my java programs run without uninstalling oracle9i.
Try to edit PATH enviroment variable and remove Oracle jre locations.(not forget restart your system to make affect).
Sorry, the old know-it-all can't help but to give his 2 pennies:This is necessary only on Windows 9x and Windows ME; unter NT, 2000,XP, and 2003 as well as in Unix systems there's no need to restart thesystem.
I believe it changes windows registry information too. Afterinstalling Oracle, my registry information for Java Plug-in 1.3.1_01was erased, so my applets couldn't start. You may need to check outwhether any thing has been changed in the registry.
