tried to run a Java program using Eclipse on my dell laptop - Windows
2000. I really do not know what I am doing wrong. I did the following -
a) downloaded J2SE SDK including the run-time environment
b) downloaded Eclipse SDK.
c) I followed the procedure listed in the tutorial - New project, new
class etc.
Now whe I try to run (build automatically) - I click on the Run as - I get
a shaded "None applicable". Tried various things - could not get it to
work.
Could some one help me ?

Click the Run Icon pulldown menu and select "Run" to bring up the Run
Configuration dialog. You do not normally make any changes to the Main pane
except perhaps to select a different workspace. Make sure "Run a product"
is checked and org.eclipse.platform.ide is selected

The switch to the Plugin's pane and choose which plugins you want to run.
If you only have the one plugin project that's all that will be displayed in
the "workspace plugins" list. You can also choose to limit which of the
other Eclipse plugins are loaded in the test instance but you can leave them
all checked for now.

Then just press Run and watch a new Eclipse start up with a new blue icon
which is your extention

Hope that helps

Sorry, that was if you wanted to run a test plugin. The process is almost
the same is you want to run a class with a Main method. except you select
the application on the left tree control in the configuration dialog

Or just select "Run As" and select Appication .

Remember, if you want to run a Java class you MUST have a Main method just
loike in C/C++

Sanjay,

Did you right click on a class with a main() in it? It should work like
this without a hitch:

Are you sure your class has a main() method with the proper signature?

public void main(String[] args) {
...
}

Make sure you have created a Java Project, rather than a simple Project.
Also, make sure there are no compilation errors in the code.

I had the same exact problem my first time running it also. I noticed in the create class pane there was a check box [] inherited abstract methods, that was checked and REMAINED CHECKED after I checked [] main and I had the problem. So I deleted everything restarted and when I checked []main I unchecked [] inherited abstract methods, and then RUN AS had Java application selectable. I'm new too so I don't know what inherited abstract methods does (nor why, if your creating it now, it is something targeted in the past tense? {how could it have inherited anything, I didn't create it yet?}) but it kinda sounded like something a Main didn't want to do.
