[platform-update-dev] Open a file programatically in Eclipse editor -- p

[Rohit Girme <rgirme@xxxxxxx>]

Hello guys,

This may be a well discussed topic for most of you. Let me explain what I am trying to do. I am trying to open a file(a .c file to be specific) external to Eclipse( not in a eclipse project in its workspace) programatically in Eclipse editor. I went through a lot of posts and forums/google search. I tried a few ways but to no avail.
Most of the things I tried I realised were for older versions of Eclipse API's.
Finally I found a way which required org.eclipse.core.runtime plugin. However the version was 2.1. I tried to include that and the code gave me no compile errors, but a runtime error saying
Exception in thread "main" java.lang.VerifyError: (class: org/eclipse/core/runtime/Plugin, method: <init> signature: (Lorg/eclipse/core/runtime/IPluginDescriptor;)V) Incompatible object argument for function call
at com.example.mouse.FileOpen.main(FileOpen.java:85)

Line 85 was
IWorkspaceRoot ws = ResourcesPlugin.getWorkspace().getRoot();

Here are some of my code snippets I tried but didnt work

1 )

   File file = new File("/home/rohit/func.c");
		IFileStore fileOnLocalDisk = EFS.getLocalFileSystem().getStore(file.toURI());
		FileStoreEditorInput editorInput = new FileStoreEditorInput(fileOnLocalDisk);


		IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
		IWorkbenchPage page = window.getActivePage();
		try {
			page.openEditor(editorInput, "org.eclipse.ui.DefaultTextEdtior");


		} catch (PartInitException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}*/

2)

  IWorkspaceRoot ws = ResourcesPlugin.getWorkspace().getRoot();
		IPath location = new Path("/home/rohit/func.c");
		IFile file = ws.getFileForLocation(location);
		IProject project = ws.getProject("External Files");


		
		if (!project.exists())
			try {
				project.create(null);
			
		if (!project.isOpen())
		    project.open(null);
		
		//IFile file = project.getFile(location.lastSegment());
		//file.createLink(location, IResource.NONE, null);


		FileEditorInput fileEditorInput = new FileEditorInput(file);
		IWorkbench workbench = PlatformUI.getWorkbench();
		IEditorDescriptor desc = workbench.getEditorRegistry().getDefaultEditor(file.getName());
		IWorkbenchPage page = workbench.getActiveWorkbenchWindow().getActivePage();


		page.openEditor(fileEditorInput, desc.getId());
		
		
		
		
			} catch (CoreException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}

Well there are few more but no point listing them because all of them gave me errors.
The point is how do I open an external file in Eclipse editor. Please point me to some article/post/ideas or code snippets for Eclipse 3.5.1. There are many out there for older versions but nothing complete. I have spent a lot of time on this and have proceeded no where...
Any help would be greatly appreciated. Thank you for your time.
