Hi,
I have problems with starting using java2script and SWT. When I use only Java2Scipt everything seems to be fine, as well as using SWT. But when I have project with SWT and then I want to change Java Build Path and add SWT as project, then this problem appears:
The project cannot be built until its prerequisite org.eclipse.swt.gtk.linux.x86 is built. Cleaning and building all projects is recommended
I cleaned both projects and nothing was changed. I use Eclipse 3.5.2. Have you any ideas, where is the problem and how to solve it?
This is what I exactly did:
1) Downladed and installed Java2Script (moving files to %eclipse%/plugin directory).
2) Downloaded SWT.
3) Created New project
package my.first.program;
public class FirstClass {
/**
* @param args
*/
public static void main(String[] args) {
System.out.println("Hello world");
}
}
4) In project Properties - changed Java2Script compiler to enabled.
5) Imported SWT as a project in the package view.
6) In project Properties - added SWT as a resource.
7) Tried to run application as Java2Script Application

Ok, problem solved.
Instead of using Eclipse 3.5.2, I've just used Eclipse 3.6.2 and appropriate J2S and now it works. Here are steps, that I took (huge thanks to my teacher, if he reads, for giving me the solution):
1) Downloaded and unpacked eclipse-SDK-3.6.2-win32.zip.
2) Downloaded and unpacked plugin j2s-2.0.0-20100601-eclipse-3.6.zip, copied 'plugin' directory to eclipse and ran eclipse -clean
3) New Java2Script SWT project
4) New class:
import org.eclipse.swt.widgets.*;
public class MyApp {
public static void main(String[] args){
Display display = new Display();
Shell shell = new Shell(display);
shell.setText("Hello world");
shell.open();
while(!shell.isDisposed())
if(!display.readAndDispatch())
display.sleep();
display.dispose();
}
}
6) Et voila, everything works.
