Flesh & Java

Hi everyone...
I want to make a simple application that integrates a flesh
interface with a Java back end. I am using Eclipse Europa
(V3.3.1.1) to make the Java part, and Flex Builder 2 (2.0.1) to
make the interface (separated IDEs, since Eclipse Europa does not
support the flex builder plugin). It does not need to be
complicated - just a "hello java" would be enough.
Im am a newbie with flex, and I just dont know if it is
possible. And if it is, how do I do it?
If someone here have a link to a tutorial or some "how-to"
that I could use, I'd be very glad :)

I would look into HTTPService. It's probably the easiest to
integrate out of the gate. HTTPService gives you the ability to
invoke a URL which can then return XML. It could be a jsp page, a
php page, or a path to a servlet..
In the future, you'll most likely want to look at Web
Services, and LiveCycle Data Services. Which allows you to invoke
methods on java objects using the MX:RemoteObject tag.

Problems with WLST embedded in java app.

Hi,
I have a problem with the WLST embedded in a java app.
I want to programatically create or reconfigure a domain from a java application. Following is a simple example of what I want to do.
import weblogic.management.scripting.utils.WLSTInterpreter;
public class DomainTester {
static WLSTInterpreter interpreter = new WLSTInterpreter();
private void processDomain() {
    if(domainExists()) {
      System.out.println("Should now UPDATE the domain");
    } else {
      System.out.println("Should now CREATE the domain");
private boolean domainExists() {
    try {
      interpreter.exec("readDomain('d:/myDomains/newDomain')");
      return true;
    }catch(Exception e) {
      return false;
}The output of this should be one of two possibles.
1. If the domain exists already it should output
"Should now UPDATE the domain"
2. If the domain does not exist it should output
"Should now CREATE the domain"
However, if the domain does not exist the output is always :
Error: readDomain() failed. Do dumpStack() to see details.
Should now UPDATE the domain
It never returns false from the domainExists() method therefor always states that the exec() worked.
It seams that the exec() method does not throw ANY exceptions from the WLST commands. The catch clause is never executed and the return value from domainExists() is always true.
None of the VERY limited number of examples using embedded WLST in java has exception or error handling in so I need to know what is the policy to detect failures in a WLST command executed in java??? i.e. How does my java application know when a command succeeds or not??

Hi,
I did some creative wrapping for the WLSTInterpreter and I now have very good programatic access to the WLST python commands.
I will put this on dev2dev somewhere and release it into the open source community.
Don't know the best place to put it yet, so if anybody sees this and has any good ideas please feel free to pass them on.
Here is the wrapper class. It can be used as a direct replacement for the weblogic WLSTInterpreter. As I can't overload the actual exec() calls because I want to return a String from this call I created an exec1(String command) that will return a String and throw my WLSTException which is a RuntimeException which you can handle if you like.
It sets up stderr and stdout streams to interpret the results both from the Python interpreter level and at the JVM level where dumpStack() just seem to do a printStackTrace(). It also calls the dumpStack() command should the result contain this in its text. If either an exception is thrown from the lower level interpreter or dumpStack() is in the response I throw my WLSTException containing this information.
package eu.medsea.WLST;
import java.io.ByteArrayOutputStream;
import java.io.PrintStream;
import weblogic.management.scripting.utils.WLSTInterpreter;
public class WLSTInterpreterWrapper extends WLSTInterpreter {

                         System.setOut(outSaveStream);
                         throw new WLSTException(_return);
          return stripCRLF(output);
     private String exec2(String command) {
          // Call down to the interpreter exec method
          exec(command);
          String err = baosErr.toString();
          String out = baosOut.toString();
          if(err.length() == 0 && out.length() == 0) {
               return "";
          baosErr.reset();
          baosOut.reset();
          StringBuffer buf = new StringBuffer("");
          if (err.length() != 0) {
               buf.append(err);
          if (out.length() != 0) {
               buf.append(out);
          return buf.toString();
     // Utility to remove the end of line sequences from the result if any.
     // Many of the response are terminated with either \r or \n or both and
     // some responses can contain more than one of them i.e. \n\r\n
     private String stripCRLF(String line) {
          if(line == null || line.length() == 0) {
               return line;
          int offset = line.length();
          while(true && offset > 0) {
               char c = line.charAt(offset-1);
               // Check other EOL terminators here
               if(c == '\r' || c == '\n') {
                    offset--;
               } else {
                    break;
          return line.substring(0, offset);
}Next here is the WLSTException class
package eu.medsea.WLST;
public class WLSTException extends RuntimeException {
     private static final long serialVersionUID = 1102103857178387601L;
     public WLSTException() {
          super();
     public WLSTException(String message) {
          super(message);
     public WLSTException(Throwable t) {
          super(t);
     public WLSTException(String s, Throwable t) {
          super(s, t);
}And here is the start of a wrapper class for so that you can use the WLST commands directly. I will flesh this out later with proper var arg capabilities as well as create a whole Exception hierarchy that better suites the calls.
package eu.medsea.WLST;
// Provides methods for the WLSTInterpreter
// just to make life a little easier.
// Also provides access to the more generic exec(...) call
public class WLSTCommands {
     public void cd(String path) {
          exec("cd('" + path + "')");
     public void edit() {
          exec("edit()");
     public void startEdit() {
          exec("startEdit()");
     public void save() {
          exec("save()");
     public void activate() {
          exec("activate(block='true')");
     public void updateDomain() {
          exec("updateDomain()");
     public String state(String serverName) {
          return exec("state('" + serverName + "')");
     public String ls(String dir) {
          return exec("ls('" + dir + "')");
     // The generic wrapper for the interpreter exec() call
     public String exec(String command) {
          return interpreter.exec1(command);
     private WLSTInterpreterWrapper interpreter = new WLSTInterpreterWrapper();
}Lastly here is some example code using these classes:
its using both the exec(...) and cd(...) wrapper commands from the WLSTCommand.class shown above.
    String machineName = ...; // get name from somewhere
    try {
     exec("machine=create('" + machineName + "','Machine')");
     cd("/Machines/" + machineName + "/NodeManager/" + machineName);
     exec("set('ListenAddress','10.42.60.232')");
     exec("set('ListenPort', 5557)");
    }catch(WLSTException e) {
        // Possibly the machine object already exists so
        // lets just try to look it up.
     exec("machine=lookup('" + machineName + "','Machine')");
...After this call a machine object is setup that can be allocated later like so:
     exec("set('Machine',machine)");Regards

Charts in WebDynpro Java (BusinessGraphics/Flex Islands)

Hello Experts,
In our project we are to display complex chart on a WebDynpro page. I did investigate the following solution but non of them could help me:
BusinessGraphics element: The element works through a Chart Engine. Chart Engine could draw a chart I need, but unfortunately BusinessGraphics element doesn't allow to change XML request to Chart Engine and supports only a half of functionality(FE I couldn't choose Column&Lines chart type). So, we couldn't use BusinessGraphics element to display needed chart.
AnalyticsChart element: The element use Flex Charting to display a chart and the element provides very small functionality as well and I cannot create needed chart.
Of cause it's possible to create needed chart in Flex, but I didn't find any way to integrate Flex and Java. Search points me to Flash Island technology, but it seems the technology was released only for WebDynpro ABAP.
Environment: NetWeaver Server 7.11 EHP1(from SDN); NetWeaver Development Studio 7.1 SP00 PAT0000 (Build id: 200807300233)
So, let me ask questions:
Is there any way to modify XML request from BusinessGraphics element to chart engine?
How can I embed Flex/Flesh application to the WebDynpro page?
Best Regards,
Dmitry

Hi Dmitry,
1. As far as I know, there is no way...
2. some hints regarding Flash Island:
To integrate flash files into your Web Dynpro application, the Adobe Flash Island UI element can be used. Flash Island is based on Adobe Flex (http://www.adobe.com/flex).
In Web Dynpro a FlashIsland is set as RootElement and spans an entire view.
To specify the flash componentu2019s data source, properties and events and to bind them to the relevant Web Dynpro objects, you can insert one or more of the following View elements into the FlashIsland:
DataSource (GACDataSource)
Property (GACProperty) into the DataSource.
Event (GACEvent).
EventParameter (GACEventParameter) into the Event.
Itu2019s also possible to insert a Property directly into the FlashIsland, if you want to bind to a context attribute directly under the ContextRoot. You can also refer to hierarchical data structures by inserting DataSources into a DataSource.
To specify the screen area, where the FlashIsland is to be displayed, insert a ViewContainerUIElement into a view.
Insert a view, e.g. called FlashView into this ViewContainerUIElement.
Open the FlashView, select the RootElement in the Outline view and choose FlashIsland from the context menu entry Replace With.
Select the RootElement and enter the name of your component to the property swfFile, for example: myFlash.swf. This file has to be stored in the mime repository. The relevant path is: .
To insert the needed additional elements to the RootElement, select it, open the context menu and choose DataSource.
To insert a Property, select the DataSource and choose Insert Property from the context menu.
Hope this helps
kind regards

OO Design and Java

I've been studying Java for a while now and am comfortable with the syntax and OO concepts. However, most of my programming experience is more traditional where you start off with an ER diagram and then develop the application to go on top of that. I have an idea for an application that I want to create using Java, but I'm having a hard time bringing the concepts of OO into a realistic design for a Java program. Can anybody out there point me to a site or resource that has an example of an OO design and what it looks like fleshed out in a Java program?
Thanks!

Entity relationship diagrams.
I associate them with database designs though.
To model in OO just try and think of everything as real world objects.
So for example if you would like to program a chessboard.
You would define a class which models the behaviour of the board which would include things like movePiece, setup board, PlayersTurn etc...
Now on that board you would have chess peieces each with thier own ability. You would have a class named abstract peiece which can not be instansiated just subclasses. Your subclass would be pawn, rock, knight etc.
Each has thier own ability. Object communicate by passing messages to one another.
Hope this helps somewhat

Java3d Tutorial: HelloJava3Da.java

Hello All,
I am beginning my journey through the Java3D tutorial. The first program (HelloJava3Da.java, pgs. 1-14 through 1-15 of the tutorial) is not behaving well for me. I searched the forum and found the suggestion to add
import java.awt.GraphicsConfiguration;
which I did. Other than this, I have not modified the code from the way it is presented in the text. This helped in that now my program will launch however I get an empty frame as opposed to the box I expect to be drawn. Eclipse tells me
Exception in thread "AWT-EventQueue-1" java.lang.NoClassDefFoundError: sun/awt/DrawingSurface
at. . .
Further forum surfing produced the suggestion to copy the .jar files from the Java3D installation from �\jre\lib\ext to \sdk\jre\lib\ext.
This resulted in no effect.
If anyone has suggestions as to how to get Java3D running as described in the tutorial I would be grateful. If it helps I am running the DirectX version of Java3D (installer = java3d-1_3-windows-i586-directx-rt.exe), and Java1.5.0.
Also, if anyone knows of a down-and-dirty Java3D/DirectX tutorial I could really use the info!
Thanks!

Back after an unaviodable break!
I made it through the first chapter of the 3D tutorial and thought I would play with it a bit to firm up my understanding. At the end of the chapter the cube is supposed to rotate around the y-axis. I thought I would flesh this out to have it also tumble around the x-axis. the code segment of interest is below.
public BranchGroup createSceneGraph()
     double Xdeg;
     double Xrad;
     double Ydeg;
     double Yrad;
     //create the root of the branch graph
          BranchGroup objRoot = new BranchGroup();
     //rotate object has composite transformation matrix
          Transform3D rotate = new Transform3D();//holds the x transform
          Transform3D tempRotate = new Transform3D(); //holds the y transform
           Xdeg = 45;
           Xrad = toRad(Xdeg);
           rotate.rotX(Xrad);
           Ydeg = 45;
           Yrad = toRad(Ydeg);
           tempRotate.rotY(Yrad);
          //The two rotations are combined by Multiplying the Transform3D objects
          //ratate and tempRotate.
           rotate.mul(tempRotate);
          //Create the TransformGroup node adn initialize it to the identity.
          //Enable the TRANSFORM_WRITE capability so that our behavior code can
          //modify it at runtime. Add it to the root of the subgraph.
         TransformGroup objRotate = new TransformGroup(rotate);
          TransformGroup objSpin = new TransformGroup();
          TransformGroup objTumble = new TransformGroup();
          objSpin.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
          objTumble.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
           objRoot.addChild(objRotate);
           objRotate.addChild(objSpin);
           objSpin.addChild(objTumble);
          objTumble.addChild(new ColorCube(0.4));
          //Create a new Behavior Object that performs the desired
          //opeation on the specified trensform object adn add it into
          //the scene graph.
          Transform3D yAxis = new Transform3D();
          Transform3D xAxis = new Transform3D();
          Alpha rotationAlpha = new Alpha(-1, 4000); //-1 = spin forever; 4000 is 4000milliSec = 4 sec)
          Alpha rotationAlpha2 = new Alpha(-1, 4000);
          RotationInterpolator rotator = new RotationInterpolator(rotationAlpha, objSpin,
               yAxis, 0.0f, (float) Math.PI * 2.0f);
          RotationInterpolator mine = new RotationInterpolator(rotationAlpha2, objTumble,
               xAxis, 0.0f, (float) Math.PI * 2.0f);
          //A bounding spnere specifies a region a behavior is active.
          //Create a sphere centered at the origin with radius of 1
          BoundingSphere bounds = new BoundingSphere();
          rotator.setSchedulingBounds(bounds);
          mine.setSchedulingBounds(bounds);
          objTumble.addChild(mine);
          objSpin.addChild(rotator);
          return(objRoot);
}//end createSceneGraph()Also if anyone knows how to change the direction of rotation I'd be interested!
Thanks

JNI, run Java methodes from C++

I'm trying to understand the JNI for a while, but can't realy figure out how to run a java methode from a C++ code.
(I've managed to do the oposit; run a C++ methode from Java, but that is not what I need.)
The thing is that I have a C++ program wich outputs a jpg picture. And I have a Java program wich is using this picture. (Picture size is from 2 - 4KB)
My temparary (not good) solution for making the picture available for the java code is to have the C program save it to a file, and then make the java program read the file once in a while.
What I would like is to have the C++ to call the methode updatePicture(byte[] newJPEG) in my javacode. How do I do this?
Parts of the C++ sourcecode:
void CExCameraView::OnTimer(UINT nIDEvent){
static int timercount=0;
     CExCameraDoc* pDoc = GetDocument();
     timercount+=pDoc->mycameraconfig->RefreshInterval ;
     if (timercount<pDoc->mycameraconfig->LoadOverHeads )
          return;
     else
          timercount=pDoc->mycameraconfig->LoadOverHeads;
     ASSERT_VALID(pDoc);
//grab one image and save it to a jpeg file
// here I'd like to call the java updatePicture methode (not save as file)
     pDoc->GrabSaveNext(pDoc->myconfig->cmsTimeOut);
And parts of the java code:
class ImageHandler {
JpegImage jpegImage; // class JpegImage extends Image
public ImageHandler() {
jpegImage = new jpegImage();
setParameters();
public updatePicture(byte[] newJPEG) {
setImage(newJPEG);
// lots of other methods

Well, you seem to be defining a C program with some imbedded java, or a java program with some native C methods. So which is it?
o If it is a C program, then you have two things to do (with respect to java):
- Start a java JVM.
- During your processing, periodically call into your JVM to process data made available by your C program.
o If it is a java program, then what you want to do -- I guess - is call a native method to start up an asynchronous (C) process, then have that asynchronous
process periodically call back into java to process results.
Overview of JNI (which you need to flesh out with some further study):
o There is the socalled invocation API, which is used to get java started.
o There is the definition of java native methods, which are then implemented in a C library (DLL on Windows), which library is loaded up at runtime by the java program, allowing the native methods to be called.
o There are JNI methods available from C that allow you to look up objects and methods, and invoke those java methods.

Ok, let's see. Write the following class:
public class Grunt {
public static void main(String[] args) {
System.out.println("Hello Mars");
}Save it as "C:\Grunt.java", compile by typing:
javac c:\Grunt.javaRun by typing:
java -classpath "C:\" GruntDoes it say "Hello Mars"? If yes, go back to your program and compare for differences (maybe you used the "package" statement?).

Erro de SYSFAIL e Queda do Ambiente JAVA (PI)

Bom Dia
Estou num projeto de NFe e atualmente esta acontecendo o seguinte cenário de Erros:
    Na SMQ2 , quando apresenta um aumento nas filas de Mensagens , aparece SYSFAIL em determinadas Filas , todas as outras travam , aumenta o numero de Filas.
   Com essa mensagem de SYSFAIL nas filas , o serve0 (Parte JAVA do PI) cai e após isso estou tendo que efetuar manualmente um STOP/START em todos os canais de comunnicação para que os R/3 voltem a emitir NFe.
    Isso esta ocorrendo com mais frequência após inserir uma nova empresa para emissão de NFe.
    Alguem poderia me ajudar a entender por que ocorre o SYSFAIL as mensagens travam e derruba o ambiente JAVA ?

But whilst that good I would like to know how I can make it tell the user something to the effect of "Your overweight" or "Your underweight". The if statement runs like this:
if (wt > max)This forum doesn't quite handle <> properly. The greater and less than symbols. So above you will see > this is the html character code for a greater than symbol so please read it as such.
And then if wt is greater than max then it will say "Your overweight".
But I can't figure out how to include it in the above program. Becuase it won't run in paint, atleast it won't the way I have done it previously. So can you think of any other ways?
Help much appreciated,
Simon

SSO java sample application problem

Hi all,
I am trying to run the SSO java sample application, but am experiencing a problem:
When I request the papp.jsp page I end up in an infinte loop, caught between papp.jsp and ssosignon.jsp.
An earlier thread in this forum discussed the same problem, guessing that the cookie handling was the problem. This thread recommended a particlar servlet , ShowCookie, for inspecting the cookies for the current session.
I have installed this cookie on the server, but don't see anything but one cookie, JSESSIONID.
At present I am running the jsp sample app on a Tomcat server, while Oracle 9iAS with sso and portal is running on another machine on the LAN.
The configuration of the SSO sample application is as follows:
Cut from SSOEnablerJspBean.java:
// Listener token for this partner application name
private static String m_listenerToken = "wmli007251:8080";
// Partner application session cookie name
private static String m_cookieName = "SSO_PAPP_JSP_ID";
// Partner application session domain
private static String m_cookieDomain = "wmli007251:8080/";
// Partner application session path scope
private static String m_cookiePath = "/";
// Host name of the database
private static String m_dbHostName = "wmsi001370";
// Port for database
private static String m_dbPort = "1521";
// Sehema name
private static String m_dbSchemaName = "testpartnerapp";
// Schema password
private static String m_dbSchemaPasswd = "testpartnerapp";
// Database SID name
private static String m_dbSID = "IASDB.WMDATA.DK";
// Requested URL (User requested page)
private static String m_requestUrl = "http://wmli007251:8080/testsso/papp.jsp";
// Cancel URL(Home page for this application which don't require authentication)
private static String m_cancelUrl = "http://wmli007251:8080/testsso/fejl.html";
Values specified in the Oracle Portal partner app administration page:
     ID: 1326
     Token: O87JOE971326
     Encryption key: 67854625C8B9BE96
     Logon-URL: http://wmsi001370:7777/pls/orasso/orasso.wwsso_app_admin.ls_login
     single signoff-URL: http://wmsi001370:7777/pls/orasso/orasso.wwsso_app_admin.ls_logout
     Name: testsso
     Start-URL: http://wmli007251:8080/testsso/
     Succes-URL: http://wmli007251:8080/testsso/ssosignon.jsp
     Log off-URL: http://wmli007251:8080/testsso/papplogoff.jsp
Finally I have specified the cookie version to be v1.0 when running the regapp.sql script. Other parameters for this script are copied from the values specified above.
Unfortunately the discussion in the earlier thread did not go any further but to recognize the cookieproblem, so I am now looking for help to move further on from here.
Any ideas will be greatly appreciated!

Pierre - When you work on the sample application, you should test the pages in a separate browser instance. Don't use the Run Page links from the Builder. The sample app has a different authentication scheme from that used in the development environment so it'll work better for you to use a separate development browser from the application testing browser. In the testing browser, to request the page you just modified, login to the application, then change the page ID in the URL. Then put some navigation controls into the application so you can run your page more easily by clicking links from other pages.

SSO between a Java EE application (Running on CE) and r/3 backend

Hi All,
Over the past few days I have been trying to implement a SSO mechanism between NW CE Java Apps and R/3 backend without any success. I have been trying to use SAP logon tickets for implementing SSO.
Below is what I need:
I have a Java EE application which draws data from R/3 backend and does some processing before showing data to the users. As of now the only way the Java App on CE authenticates to r/3 backend is by passing the userid and pwds explicitly. See sample authentication code below:
BindingProvider bp = (BindingProvider) myService;
Map<String,Object> context = bp.getRequestContext();
context.put(BindingProvider.USERNAME_PROPERTY, userID);
context.put(BindingProvider.PASSWORD_PROPERTY, userPwd);
Now this is not the way we want to implement it. What we need is when the user authenticates to CE ( using CE's UME) CE issues a SAP logon ticket to the user. This ticket should be used to subsequently login to other system without having to pass the credentials. We have configured the CE and Backend to use SAP logon tickets as per SAP help.
What I am not able to figure out is: How to authenticate to SAP r/3 service from the java APP using SAP logon tickets. I couldnt find any sample Java code on SAP help to do this. (For example the above sample code authenticates the user by explicitly passing userid and pwd, I need something similar to pass a token to the backend)
Any help/pointers on this would be great.
Thanks,
Dhananjay

Hi,
Have you imported the java certificate into R/3 backend system ? if so.
Then just go to backend system and check on sm50 for each applicaion instance of any error eg.
SM50-> Display files (ICON) as DB symbol with spect.(cntrlshiftF8)
You will get logon ticket details.
with thanks,
Rajat

Partner Application written in other language than PL/SQL and Java

I have an application written in another language than PL/SQL or Java. I want to integrate this application as an Partner apps where I use the same user repository as Portal.
Can I integrate the application by calling a stored PL/SQL-procedure based on the PLSQL SSO APIs examples that authenticates the user based on the username/password in portal and redirects the user to the application ?
Are there any examples / references where this has been done ?
Jens

Check out the PDK referance for URL-Services, which allow you to integrate with any web based service/content.
