could not find framework in eclipse RCP application

Question

I have developed one eclipse RCP application which I am calling from my own Java program.
When I run my own Java program from command prompt (windows) it is perfectly working and giving the results.

But when I have integrated with the ant build script in eclipse 3.2 it is giving the following problem:

!ENTRY org.eclipse.core.launcher 4 0 Dec 02, 2009 10:53:17.608
!MESSAGE Exception launching the Eclipse Platform:

Can you please help me what could be the possible reasons for this error.

Answer 1

As mentioned in this thread, you:

• do not only have to add the platform plugins you wish to export to the list of dependent plugins of your feature,

• but you also have to the list of included plugins

(See this project for instance)

Make sure you "Validate Plug-ins" before you launch your RCP (see this thread).
With the Launch Configuration Dialog, in the "Plug-ins" Tab, there is a "Validate Plug-ins" button that you can click to verify that all the dependency of the "selected" plug-ins are satisfied.
If there are some errors, you can click the "Add Required Plug-ins" to correct the error.
