Eclipse 怎样在java application 模式的项目中运行Job
我在eclipse 中建立一个新的Job
import java.text.SimpleDateFormat;
import java.util.Date;
import org.eclipse.core.runtime.IProgressMonitor;
import org.eclipse.core.runtime.IStatus;
import org.eclipse.core.runtime.Status;
import org.eclipse.core.runtime.jobs.Job;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;

public final class Clock {

public Clock() {
super();
}
public static void main(String[] args) {
// TODO Auto-generated method stub
Job job = new Job("Clock Job") {
protected IStatus run(IProgressMonitor monitor) {
System.out.println("Run in Job");
Display display = new Display();

Shell shell = new Shell(display);

shell.setText("Clock in Job");

shell.setSize(200, 100);
SimpleDateFormat bartDateFormat =new SimpleDateFormat("MMMM-dd-yyyy EEEE HH-mm-ss-SSS");
Date date = new Date();
Label lab = new Label(shell,SWT.NONE);
lab.setText(bartDateFormat.format(date));
lab.pack();
shell.pack();
shell.open();
while (!shell.isDisposed())

{
if (!display.readAndDispatch())

display.sleep ();

}

display.dispose ();
lab.dispose();
return Status.OK_STATUS;
}
};
job.schedule(); // start as soon as possible
Display display = new Display();

Shell shell = new Shell(display);

shell.setText("Clock in main");

shell.setSize(200, 100);
SimpleDateFormat bartDateFormat =new SimpleDateFormat("MMMM-dd-yyyy EEEE HH-mm-ss-SSS");
Date date = new Date();
Label lab = new Label(shell,SWT.NONE);
lab.setText(bartDateFormat.format(date));
lab.pack();
shell.pack();
shell.open();
while (!shell.isDisposed())

{
if (!display.readAndDispatch())

display.sleep ();

}

display.dispose ();
lab.dispose();
System.out.println("Run in main");
}

}


编译没问题，但是运行时会

请问怎么才能在Java application模式中运行Job?

[霜之哀伤]

lz是3.2版本的？

不要用 run as javaapplication
用，run as java bean


3.3版本没这个问题

友情提醒楼主早日结贴。

最后解决的方法就是虽然他是一个plugin但是我还是用Run as Java application，这样虽然解决了问题但是不知道怎么才能让他脱离Eclipse 运行。谢了兄台，先把分给你吧。
