HiI am pretty new to visad and currently exploring its usage for my applications. So far I was able to write some simple applications.
I have run into a problem when I tried to call a visad application through and applet's "submit" button on a web site as in the following format:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { Util.invoke(false,false, new Runnable() {
public void run() {
com.app.lt.CreateImage imagePr = new com.app.lt.CreateImage();
try {
BufferedImage myImage =imagePr.plotImage();
} catch (RemoteException ex) {
ex.printStackTrace();
} catch (VisADException ex) {
ex.printStackTrace();
}
}
});
.
.
the exception I get is;
Exception in thread "AWT-EventQueue-1" visad.VisADError: cannot call
getImage() from Thread: AWT-EventQueue-1
at visad.DisplayImpl.getImage(DisplayImpl.java:2630)
at visad.DisplayImpl.getImage(DisplayImpl.java:2614)
at com.app.lt.CreateImage.plotImage(CreateImage.java:94)
where line 94 has the following code;
return display.getImage();
and display object is;
DisplayImplJ2D display = new DisplayImplJ2D(" ", 700, 500);
I looked through old e.mails and it seems like this works for everybody
else. It works fine if I run the application by itself. Like I said I
am a new user and there maybe much easier way to do this but I just
don't know yet. any help is greatly appreciated... thanks in advance..
