Not ableto migrate from eclipse 3.x to eclipse 4.x

We've an RCP application based on 3.x api we are trying to migrate it to eclipse 4.x. The problem is some part of the code was using eclipse internal classes present in the workbench.jar . SO i added the workbench.jar JAR from the previous eclipse(HELIOS) to my new eclipse(KEPLER) this resolved the errors .But my application is not able to start.So just wanted to know is it the correct approach

1.Can I have two workbench.jar JARS(3.105 and 3.6) in my application.

2.If no then is there a way to search for the internal classes which I was using previously in the new jars I was mainly using the internal classes related to layout and prespectives(like : org.eclise.ui.internal.layyoutPart ,org.eclipse.internal.ui.perspectives)

3.Is there a way using which I can avoid rewriting the code.

Eclipse 4.x is a very substantial rewrite so there is very little chance that internal classes from 3.x are going to work. Multiple workbench jars is not going to work in any case.

The layout and perspective classes you mention do not exist in Eclipse 4.x, you are going to have to rewrite your code.
