hey sabre why not just help me? instead of posting
annoying replies. You want me to browse all the post
two weeks ago to find what im looking for. stoopsMost regulars to this forum find X-posting annoying. Since you are lazy and want me to search the posts of the last couple of week for you, I find you very annoying.

Tutorial for Workflows programming

Hi everybody
I try to operate on task in workflow from outside (exactly from WebDynPro). I have problems with using apis
SAP_WAPI*. I am locking for a good tutorial or example to using this apis. I am graceful for any tips.
Regards
Bogdan

I know why i have got message 'can't start task in status ready'. That is part of SAP_WAPI_WORKITEM_COMPLET:
*- check status 1
 if lv_wi_handle->m_sww_wihead-wi_stat = swfco_wi_status_ready or
 lv_wi_handle->m_sww_wihead-wi_stat = swfco_wi_status_error or
 lv_wi_handle->m_sww_wihead-wi_stat = swfco_wi_status_cancelled or
 lv_wi_handle->m_sww_wihead-wi_stat = swfco_wi_status_completed or
 lv_wi_handle->m_sww_wihead-wi_stat = swfco_wi_status_checked.
 ls_t100msg-msgid = 'WL'.

 ls_t100msg-msgty = 'E'.
 ls_t100msg-msgv1 = lv_wi_handle->m_sww_wihead-wi_id.
 ls_t100msg-msgv2 = lv_wi_handle->m_sww_wihead-wi_stat.
 raise exception type cx_swf_run_wim
 exporting
 t100_msg = ls_t100msg
 wi_id = lv_wi_handle->m_sww_wihead-wi_id.
 endif.
I should earlier that code analyze
But I still don't know which status should the task have and how can i it change.

What kind of math sould I know for successful programming in java 2d?

I want to write fun and little games in Java but am blocked by lack my maths knowledge.I mean I am not
able to do what I want.
I know only matrix,determinant,sets,logic,and a little graph theory.I forgot some maths such as differential equation,
probability,numerical methods due to my being math-phobic.
So please what maths should I learn or improve to full-fill my wish.
best regards,
saddened vegeta

For any programing:
You should know basic number representations and when the computer approximates numbers or has actual number values in each (decimal vs integer types).
You should understand overflow and underflow.
Know what a significant digit is and why it is significant and what makes the others not significant.
(NOTE: the previous are things that will save you a world of frustration in "I'm not getting the right answer.")
For graphics and gaming:
If you don't know Trig, then you should become at least familiar with how to use the functions.
Basic Geometry or at least have a reference to and a working knowlege of formulas--a lot of this just goes hand in hand with Trig.
You should know basic physics on ballistics--Force, Distance, Acceleration, Gravity, Friction (if you can ignore this component, then things are a whole lot simpler--but you should at least know why).
I'm sure there is a lot more, but off the top of my head this will do. If you know these few things, then you'll be far ahead of many.

@khansartaj
the main method is the method used by the VM to initiate an application. You need to implement this method in order to run the class. The parameter string[] args is a list of the commandline parameters passed to your application.

Kernel programming using Java

I'm currently doing a research in computer security and would like to develop a system which can deal directly to linux kernel in order to enhance the security. During my research I found that Java is a type-safe language which is more secure if I develop my system compare to C language which is lack of type-safe. So I decided to use Java to develop my security system which will enhance resources management in Linux. My question is, does anyone know whether Java could be used in kernel programming or not? Where could I get some sort of references related to my work especially tutorial about kernel programming using Java. I would appreciate if anyone of you could help me in this matter. TQ

I'm currently doing a research in computer security ...You might want to do a bit more research into the languages.
What you are discussing has nothing to do with security.
If you are writing kernel services then java is probably ill suited because the normal implementations use garbage collection which is not under your control. This makes it hard (if not impossible) to control timing.
If your sole desire is type safety then C++ provides better type safety and provides more control over types as well.

Infinite loop error after using Java Sun Tutorial for Learning Swing

I have been attempting to create a GUI following Sun's learning swing by example (example two): http://java.sun.com/docs/books/tutorial/uiswing/learn/example2.html
In particular, the following lines were used almost word-for-word to avoid a non-static method call problem:
SwingApplication app = new SwingApplication();
Component contents = app.createComponents();
frame.getContentPane().add(contents, BorderLayout.CENTER);I believe that I am accidentally creating a new instance of the gui class repeatedly (since it shows new GUI's constantly and then crashes my computer), possibly because I am creating an instance in the main class, but creating another instance in the GUI itself. I am not sure how to avoid this, given that the tutorials I have seen do not deal with having a main class as well as the GUI. I have googled (a nice new verb) this problem and have been through the rest of the swing by example tutorials, although I am sure I am simply missing a website that details this problem. Any pointers on websites to study to avoid this problem would be appreciated.
Thanks for your time-
Danielle

um, yeah, you definitely have a recursion problem, that's going to create an infinite loop. you will eventually end up an out of memory error, if you don't first get the OS telling you you have too many windows. interestingly, because you are deferring execution, you won't get a stack overflow error, which you expect in an infinite recursion.
lets examine why this is happening:
in main, you call new MGui().
new MGui() creates a runnable object which will be run on the event dispatch thread. That method ALSO calls new MGui(), which in turn ALSO creates a new object which will be run on the event dispatch thead. That obejct ALSO calls new MGui(), which ...
well, hopefully you get the picture.
you should never unconditionally call a method from within itself. that code that you have put in the constructor for MGui should REALLY be in the main method, and the first time you create the MGui in the main method as it currently exists is unnecessary.
here's what you do: get rid of the MGui constructor altogether. since it is the implicit constructor anyway, if it doesn't do anything, you don't need to provide it.
now, your main method should actually look like this:
public static void main( String [] args ) {
SwingUtilities.invokeLater( new Runnable() {
    public void run() {
      MGui app = new MGui();
      app.createAndShowGUI();
}// end mainyou could also declare app and call the constructor before creating the Runnable, as many prefer, because you would have access to it from outside of the Runnable object. The catch there, though, is that app would need to be declared final.

Setting up Java 3D in linux for Eclipse programming...

I'm trying to start programming with Java 3D, but I think I'm having problems with the initial setup. I installed Java3D using the amd64 bin script into the active jre: /usr/lib/jvm/java-6-sun/jre/. I'm working in Eclipse and have included j3dcore.jar, j3dutils.jar, and vecmath.jar in the build path. It compiles just fine.
My program is a very simple test from a tutorial:
package tests;
import com.sun.j3d.utils.universe.SimpleUniverse;
import com.sun.j3d.utils.geometry.ColorCube;
import javax.media.j3d.BranchGroup;
public class Hello3d {
public Hello3d()
 SimpleUniverse universe = new SimpleUniverse();
 BranchGroup group = new BranchGroup();
 group.addChild(new ColorCube(0.3));
 universe.getViewingPlatform().setNominalViewingTransform();
 universe.addBranchGraph(group);
public static void main(String[] args) {
 new Hello3d();
 System.out.println("blah");
}And I get the following exception when it runs:
Exception in thread "main" java.lang.NoClassDefFoundError: javax.media.j3d.X11NativeConfigTemplate3D

 ...12 moreI installed libgcj via Synaptic (I'm running Ubuntu) but still get the same error, so I'm unsure how I should proceed. Any ideas what's wrong?

A late reply but I encountered the same issue. For anyone who googles this thread and everyone else I have a solution!
Use Sun's JRE! It seems GCJ doesn't support the API 100% so what you need to do is
$ sudo apt-get install sun-java6-jreand then in Eclipse change the default workspace JRE or the project JRE to the new one. Eclipse apparently only scans the system for installed JREs on first run so you need to add it manually:
Right click on project, select Properties. Go to panel Java Build Path and select tab Libraries. Select your JRE from this list, it should be named similar to java-1.5.0-gcj-4.3-1.5.0.0, and click Edit. Click Installed JREs and then Add.
Enter a descriptive JRE name, such as Java 6 Sun JRE 1.6.0.x and then enter the path where the JRE is installed - on my Ubuntu machine it's in +/usr/lib/jvm/java-6-sun/jre+.Select OK twice, select the new JRE as the default for all projects in the workspace or select it via the Alternate JRE setting which will only use Sun's JRE for this project.
Good luck!

GOOD tutorial for java?

Hi, I am looking for a good tutorial for java. I cant understand my teacher's lectures, because they are always presented as a slide show and she just reads the slides in a monotone voice. (Not to mention her thick asian accent). So any one?
*Note=A good tutorial is the one that shows coding examples, analysis of concepts etc
