Hey guys...I met a very annoying problem while I am trying to put a program integrated Processing on a tomcat server...I checked many solutions about this. Most of them is saying that the applet on the server side is so-called heavy weight component...But I can't shift them into client side cause I just want processing to make a picture and then send this to the client.

So I think I didn't call the applet display or some interactive operations..I don't know why I have this problem "using java.awt library in linux X11 display problem"..So if I change the tomcat setting as most of people said "-DJava.awt.headless=true", it will get into another error..Both errors show that there is a problem in Papplet.java 244 lines in the source code of processing:

  static public final int MENU_SHORTCUT = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask();

Can somebody help me , I got stuck here like ages.......

 Hey guys I met a problem while I was woking with Processing...

So I imported the required library locally and it's wokring fine...

But when I just put this in the maven dependency..The program will always got stuck at:

wordcram.init();  //wordcram is the object of processing.

And it's not giving me an error, the program is just stucking there not moving then....I am wokring on a java project in eclipse..Can anybody help me??

I am working on with Processing in eclipse. So it's not like the sketchbook that I can save the picture directly.

So for my code I just write:

public class Test extends PApplet {

  

    public void setup() {
      ....

     ......
        this.save("/home/yu/workspace/ppooc1"); / / Here it's just defult saving as .tif format. I don't know how to set to changeit into anohter format, can somebody help me ??

    }
}

Hey, I met a problem while I want to run the applet of prcessing thing in my normal java application.
So here is the definition of my processing part:


import processing.core.*;
import wordcram.*;

public class CasWordCram extends PApplet {
    /**
     *
     */
    WordCram words = new WordCram(this);
    @Override
    public void setup() {
        System.out.println("hello++++++++++&&&&&&&****************");
        this.size(500, 400);
        this.background(255);
        this.words.fromWebPage("http://en.wikipedia.org/wiki/Word_cloud");
        this.words.drawAll();
        this.save("test");
    }
}
//So the thing above is running perfectly and I can get the applet window which is fine. (ONLY RUN IT AS A JAVA APPLET INDEPENDENTLY).

public void finishProcessing() {
 
        CasWordCram wordcram = new CasWordCram();
        wordcram.setup(); 
    }
//So this function above is defined in a normal java application. It's under one class. And I built the wordcram class from the defined class above.

 But after compiling it as JAVA APPLICATION. it shows this error:

Exception in thread "main" java.lang.NullPointerException
    at processing.core.PApplet.size(Unknown Source)
    at processing.core.PApplet.size(Unknown Source)
    at de.fhg.iais.kd.tm.quote.casAnnotation.CasWordCram.setup(CasWordCram.java:21)


Can somebody help me with this? I got stuck by this for hours......Thank you for your patient reading~~
