Trying to open an editor on a textfile. I got an IFile that seems to work
but when create a new FileEditorInput with the ifile the program crash.


IWorkspace ws = ResourcesPlugin.getWorkspace();
IProject project = ws.getRoot().getProject("project");
String name = "/Users/usr/workspace/project/file.txt";
IPath location = new Path(name);
IFile file = project.getFile(location.lastSegment());
System.out.println("IFile: " + file.getname()) // ok

IEditorInput editorInput = new FileEditorInput(file);
// crash!!!

IWorkbenchPage page = window.getActivePage();
if (page != null)
page.openEditor(editorInput, "org.eclipse.ui.DefaultTextEditor");

You need to add org.eclipse.ui.ide as a required bundle in the
'Dependencies' tab of your MANIFEST.MF file in your META-INF folder and
not configuring your Java Build Path through your project's properties.

You need to give us more information to work with here.

What exactly are you trying to do?
What file are you trying to open?
What do you see?
What did you expect to see?
What is not working?

I'm trying to open a file outside the workspace. When I do that I get an
IPath with the right path to the file. Then when I make the IFile (IFile
file = project.getFile(path.lastSegment());) with the path the IFiles
location isn't the same as the path. So when the the program tries to
open the file it look at the wrong location. It moves the location from
the workspace directory to the runtime-EclipseApplicication directory so
then it cant find the file.

When i run the program it opens a texteditor that says it can't find the
file.

They added API in 3.3 for this. You want to use FileStoreEditorInput
instead for files that aren't in the workspace. Google around for
information about EFS (Eclipse File System) to figure out how to get an
IFileStore for your FileStoreEditorInput constructor.

You don't even need to create the editor input. Simply do this:
IFileStore fileStore = EFS.getLocalFileSystem().getStore(uri);
IDE.openEditorOnFileStore(page, fileStore);
