Oracle Apps is not opening in Vista

Oracle apps will not open directly in Vista OS.

Cause: jvm.dll which will come with Jinitiator 1.3.x.x  will not support Vista OS

Solution:  download(from google) and install JRE 1.5.0_10 or above even 1.6 works 

Click here to download JRE latest version and jvm.dll

you can directly repalce downloaded jvm.dll with Jinitiator dll or you can install JRE and do the same as following

Copy the jvm.dll from 

x:\xxx\Java\jre1.x.x_x\bin\client\jvm.dll

to 

x:\xxx\Oracle\Jinitiator 1.3.1.x\bin\hotspot\jvm.dll

example x:\xxx == C:\ProgramFiles

after that restart/reboot the system and try to open the Oracle apps

it may works for other Jinitiator versions also... :)
