Exception while starting grails from STS

Problem: Getting java.lang.ClassNotFoundException: sun.tools.native2ascii.Main while starting grails application from STS.

Solution: Go to build path. Change your default system JRE to JDK. You are good!

Specifying JVM in STS

Although STS is build on top of elcipse it uses STS.ini instead of eclipse.ini for inititializing startup parameter. You need to specify JVM in this file as follows:

-vm
C:/Program Files/Java/jdk1.6.0_22/bin/javaw.exe

Make sure:

1. -vm and the path are in two seperate line.
2. This option is set before -vmargs.
