run->run..->java application and for that particular swt applicn i set the
VM arguments fields as:

-Djava.library.path=D:\eclipse
2.1.0\eclipse\plugins\org.eclipse.swt.win32_2.1.0\os\win32\x 86

Where D:\eclipse 2.1.0\eclipse\plugins\....is my root installtion directory

My project name is org.eclipse.test.(which is plugin project).My project
tree is like this:
--org.eclipse.test
--src(this folder automatically done while creating blank plugin prjct)
--org.eclipse.test(package name)
--Testswt.java(my swt applicn)

Now when i run(as java applicn)i get error as:

"could not find the main class.Program will exit"

Can anyone tell me From beginning how to execute swt applicn.which project
i have to create.(plugin project right?)

regards
steven

You must have a main method in your class(es) for the lunch to work.
It looks like this: public static void main(String[] args)

Go into the run dialog, double click java application. This will refresh
the class listings for open projects. Click (highlight) the name of the
class you are trying to run. Then choose run.
