Zest Graph - editable or non-editable? How does one start making a class?

Question

I'm working on a project, where I intend to make a class in JAVA using which I could create a graph. To put it in detail, I'd like to create 2 interfaces - VERTEX and EDGE, each one having methods like addVertex(), addEdge(), neighborVertex(), numOfNeighbors() etc., and my class (call it Graph) will implement the aforementioned interfaces.

I'm a real novice at JAVA at the moment, and was wondering how to go ahead using ZEST? Also, would the graph be editable if I use ZEST?

The tutorial by Lars Vogel helped me, but I'm still unable to get it working. How can I resolve the following errors?

If you want to visualize your graph with Zest, you would have to transform your own graph objects into Zest graphs, or use the Zest objects in the first place. Have a look at some samples in the Eclipse wiki and this tutorial.

The graph would not be editable with Zest (which focuses on visualization), but being SWT-based you can make your graph interactive (add listeners to nodes etc.). If you want graph editing have a look at Graphiti or maybe something like JUNG.

Hey, Fabian! Thanks, man. Still got something to get your help for. Please have a look at my question (the 'edit' especially). – Anirudh Sharma Aug 30 '12 at 09:20
@Anirudh This is what I would try: in your launch configuration, tab 'Plug-ins', in the top, for 'Launch with', choose 'all workspace and enable target plug-ins' or: select 'plug-ins selected below only', then click 'Deselect All', select your own plug-in, and click 'Add required plug-ins'. – Fabian Steeg Aug 30 '12 at 12:36
That's what I did before editing the question last time. I'm actually not able to figure out what plug-ins I need in addition to the ones I know are required. I selected all and tried, and also deselected all and chose the ones I thought were required. Could you please go through again and let me know where I'm missing out? Has it got to do something with the following showed in the error log view? "The following is a complete list of bundles which are not resolved, see the prior log entry for the root cause if it exists:" – Anirudh Sharma Sep 03 '12 at 08:52
