Hi everyone, I'm working with Eclipse Helios Service Release 2. I've been trying for a while to open an editor programmatically. Basically I need to create a file dynamically and then open the corresponding editor in Eclipse.

I was trying to do something like it's detailed here: http://wiki.eclipse.org/FAQ_How_do_I_open_an_editor_programmatically%3F, but in this line:

EFS.getLocalFileSystem().getStore(fileToOpen.toURI());

I get a NPE, here is the log:
Exception in thread "main" java.lang.ExceptionInInitializerError
	at org.eclipse.core.filesystem.EFS.getLocalFileSystem(EFS.java:439)
	at org.eclipse.pde.uiimpact.refactoring.handlers.Test.createFile(Test.java:42)
	at org.eclipse.pde.uiimpact.refactoring.handlers.Test.main(Test.java:27)
Caused by: java.lang.NullPointerException
	at org.eclipse.core.internal.filesystem.InternalFileSystemCore.<init>(InternalFileSystemCore.java:49)
	at org.eclipse.core.internal.filesystem.InternalFileSystemCore.<clinit>(InternalFileSystemCore.java:25)
	... 3 more

This is giving me such a hard time, the example of that FAQ is for Eclipse 3.3, I'm not sure if something should be different for Helios. I just can't find anything that works for me.

I'd really appreciate if anybody can help me.

Thanks!!

Looks like you start your app as normal 'Java Application' instead of as
'Eclipse Application'.
