Strange problem about navigation tree loading.

Hi all:
   I have one workset which contains 2 iviews. And there is one navigation tree in the left.
   Sometime when some users click on the navigation tree, the EP always display "loading..." and it seems hangs......
   The problem is very strange and I cannot see any error log.
   Anybody have same experience ?
   We are using EP7 sp9.

Please have a look at SAP Note : 976331

A strang problem about Resin database connection pool

I am a beginner，hope somebody can help me.

Short code causes a strange problem - About the list again -- please read!

Hi again people. Maybe you remember my project - has a list, that you can search thru using a text field. During the work I got stuck on a strange problem ( Again :-( ) My app has one text field, one combo box, one list and a text field once more. The code should do the following ->
*1. Load the list, no problem with that.*
*2. Show the elements of the list, that match the selected group in the combo box,no problem.*
*3. Search thru the list using the text field,no problem.*
4. When the user selects an element from the list, it should display its info in the second text field. This also works fine, but when after looking at info of one of the elements the things on numbers 2 and 3 ( look up! ) stop working. I must say that everything works fine until user selects an element from the list. I couldnt understand this kind of behavior so I am asking you to help me please.
The code is very simple:
import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
class the_window extends JFrame implements DocumentListener, ItemListener, ListSelectionListener {
    FileReader reader;

    JTextField info_field = new JTextField();
    String groups[] = {"1. group" , "2. group"};
    JComboBox groups_cmbx = new JComboBox(groups);
    the_window(){
        super("the Window!");
        JPanel panel = new JPanel(null);
        Container c = this.getContentPane();
        c.add(panel);
        text_field.setBounds(10,10,170,25);
        text_field.getDocument().addDocumentListener(this);
        panel.add(text_field);

refresh();
public void removeUpdate(DocumentEvent e){
refresh();
public void insertUpdate(DocumentEvent e){
refresh();
public class Main {
public static void main(String[] args) {

Now, can you please tell me whats wrong with this?
For the "data.txt" make a new text file using *notepad* and copy the following line into the document:
_1. element#1. info#0;2. element#2. info#0;3. element#3. info#1;4. element#4. info#1;5. element#5. info#1;_

Darryl.Burke wrote:
Keith, thanks for making that readable. So here's the diagnosis -
In the refresh() method, calling defaultListModel.clear() results in a valueChanged(...) event in which this method calldefaultListModel.getElementAt(list.getSelectedIndex())results in the exception noted, as getSelectedIndex returns -1, the list being empty... you can't getElementAt(-1).
I haven't analyzed all the code nor checked whether is now works as desired, but this small change to valueChanged counters the exception being thrown.   public void valueChanged(ListSelectionEvent e) {
infoField.setText(""); // do this unconditionally
if (list.getSelectedIndex() != -1) {
String value = (String)defaultListModel.getElementAt(list.getSelectedIndex());
for(int i = 0; i < numFields; i++){
if(value.equals(matrix[0])){
infoField.setText(matrix[i][1]);
break;

Yea! You were right! I didnt think that calling *list_model.clear();* will result in calling *valueChanged()* ........
That was some *clear()* thinking :-) Thank you!

Conception problem: Integrating navigation tree

Hi all,
In order to help users to visualize what actions they can perform, i would like to add a navigation tree into an existing web app.
My first idea was to create a new Index.jsp divided into two frames, the first one get the tree and the second is used for displaying the .jspx called. Problem, in the browser address bar the only thing which is displayed is "http....index.jsp". I no longer have the adress of each page and that lead to difficulties in securizing the app, and some problems in using browser navigation capabilities.
A solution could be to just create my tree into a new page then including a button to go to this page from all the others, but my idea was to let this tree displayed everytime (or may be adding a way for switching rendered property).
A last possibility i imagined is to include the tree into each page, but before doing this (there is a lot of pages to modify) i would rather than some experimented people give me some advices:
What is the best solution?
Should i use a frame based sharing or another way?
Thanks in advance,
Tif

Hi frank,
Thank you for being interested.
This web app works like an ERP (enterprise resource planning). Around 50 persons should use it. Depending on their roles they have rights for view, create, modify data in different modules (business development, human resources, instrument maintenance, etc). Each module contains many pages (customer creation and edition, quotation management, etc).
The tree displays each module and some pages of each represented by hyperlinks. Depending on the user who is logged in the tree displays less or more possible navigations. It should enable to navigate quickly from one page to another by these links. User can choose to hide it. So if user well know the application he doesn't need really to use the tree (there is other way to navigate), but for beginners it should display in a simple way all the tasks they can perform depending on their role.
I hope this explanation is more clear. In my last tries, i'm putting it in the menu3 facet of my pages, but i've problem to target the window. When i put _parent display is correct but the browser address bar display "http...myTree.jsp" and not the called page address. I'm working on, so i very appreciate all tips, advices you can give to me
Thanks and regards,
Tif

A strange problem about InputStream

I meet a strange problem.
I have a data file named data.dat whose size is 16k.
I write a passage of code to read the binary data from data.dat
       byte[] gbData = new byte[8177 * 2];
       // it's length equals to the size of data.dat
       InputStream in = ClassLoader.getSystemResourceAsStream(
           "com/sunway/james/st/res/data.dat");
       in.read(gbData);
       in.close();When I run the program, It's can work well. Then I put all class and resources into a jar file.
When I run the jar file, I can only get first 600 (and serval more) bytes right. left bytes are 0.
Who can tell me what happen?

Thank you.
I tried to use java.nio to read the data, and there is still the problem.
flowing is the new codes:
        FileInputStream in =
            new FileInputStream("com/sunway/james/st/res/BIG5.dat");
        ByteBuffer buffer = ByteBuffer.allocateDirect(1024);
        in.getChannel().read(buffer);
        byte[] big5Data = buffer.array();
        in.close();

Strange problems about my projects(efficiency,event structure,queue)

hey,guys,i am a labview user from china,so forgive me about the chinese words of my projest. i found something wrong with my work. .
there are two functions in my "While loop", the first one depends on "queue" and is to get information from UART, the second one is "event structure" to send information through UART. my problems:
1. i can not stop while loop by pressing "停止“, and i find two ways to stop it. first, i press"停止”,then, i press any buttons that can trigger "event structure"twice, at last, while loop can stop.the second way, i press buttons for "event structure" one time, then "停止”， and then the same button for"event". it also works
2.my work does not run efficiently. you guys can try. once you press buttons for "event structure", it responses very slowly,and if you press many times,the whole program seems like suspending.i have added a LED named test at the front panel, it should light once you press "运行“. and it also shows how slow the whole program is.
i have attached my work, and my main vi is "串口通信主VI".
can any body give me some suggestions? thanks a lot

Your event structure will execute exactly once per loop of the main loop, thus the other three loops must stop before handlig the next event. You will also get a race condition between the top loop and the events when writing.
I'd put the top loop as the timeout case in the event and place the loop around the event for starters.

A strange problem about batch input (VA01)

Dear experts,
I have created one batch input program about VA01,When the selection screen is full window and run,one error occurs.Opposition the screen is not full window ,and the error do not occur.
Could you help me?
Thanks and regards,
collysun

Hi Collysun,
The problem what you are facing is due to the resolution setting of individual desktop. This is a known issue in BDC's. Pls do one more recording of VA01 by putting the screen into default size from the tri color button that comes at the right corner of the application tool bar of your session window.
The advantage is that when the BDC is executed in background automatically the size of the session which is doing the job for you goes to the original size as the one in the recording and it will work irrespective of the windows screen resolution.
Cheers

Strange problem about using JSTL

Dear all,
I've got a strange proble when using JSTL with tomcat.
I've got two strings as the following:
     String id_string = (String)session.getAttribute("user_id");
     System.out.println(id_string);
     String valid_user = (String)session.getAttribute("valid_user");
The "println" call tells me that "id_string" has a valid value.
But when I use it like this in the same page:
<a href="springapp/blog.htm?id=<c:out value=${ id_string " /><c:out value="${ valid_user }" />" >test
I can only get "valid_user"'s value.
"id_string" is not print out to the page.
Would anyone please help me out?
Any help would appreciated and thanks in advance.

"id_string" is not print out to the page.Your session attribute is called "user_id" which you're fetching correctly earlier. But in the <c:out> tag, you're trying to read "id_string" which is the name of your local variable and not in any scope. "valid_user" works because you've named your local variable the same as your scope attribute, so the value being printed out is from the scope and not your local variable. As far as I know, JSTL doesn't work with local scriptlet variables, it only access variables in the four scopes: page, request, session and application
You should use the <c:set> tag to set a variable value. Try not to mix scriptlets and tags, it's frowned upon and will probably cause you problems later.

A strange problem about mighty mouse's trackball

My mighty mouse's trackball works very well on OSX, but it failed to work on Windows, it worked very well on Windows XP and 2008 previously, what is the problem? Thanks!

Solved the problem myself. It's weird that the bluetooth caused the problem, I installed the bootcamp correctly, and my mouse work properly except trackball, and I found that the bluetooth driver is not properly installed. But how come my mouse could still work? Hate Windows...

Very strange problem about GameCanvas.getHeight()

i wrote a class extends GameCanvas and call getHeight() to get the screen height.When i used WTK emulater,everything is ok,
But when i used the Nokia S60 emulater whose height is 208, i got just 144!
I thought that may be S60's problem,and i opened the Nokia S60's MIDP2 sample "Sheepdog",added the method getHeight().Then I got the right result 208!
Even i used SetFullScreenMode(true),the problem existed also.
Nokia's code is all based on MIDP2 without any Nokia's own package,But Why i get the difference by the same method and the same emulater???
THX!!!

Thanks for ur reply.
that's a segment code of Nokia demo project SheelpDog
class SheepdogCanvas
extends GameCanvas
implements Runnable
// shared direction constants
static final int NONE = -1;
static final int UP = 0;
static final int LEFT = 1;
SheepdogCanvas(SheepdogMIDlet midlet)
super(true);
this.midlet = midlet;
System.out.println(Integer.toString(this.getHeight())); //i added
setFullScreenMode(true);
System.out.println(Integer.toString(this.getHeight()));//i added
graphics = getGraphics();
Both outputs are 208.
And this code below is mine:
public class Displayable1 extends GameCanvas implements CommandListener {
public Displayable1(boolean suppressKeyEvents) {
super(suppressKeyEvents);
System.out.println(Integer.toString(this.getHeight()));
setFullScreenMode(true);
System.out.println(Integer.toString(this.getHeight()));
Both outputs are 144
moreover,the Sheepdog is a sample of Nokia Developer's Suite 2.2 for J2ME(TM) (15.6.2004),u can find it in http://www.forum.nokia.com/main/0,,034-2,00.html
the emulater tested by both codes is Nokia S60_J2ME SDK 2nd FP2,u can find it in http://www.forum.nokia.com/main/0,,034-483,00.html

Very strange problem when navigating in Contribute

I have a user at a remote location, connecting via a VPN
router. For some reason at some point during her usage of
Contribute, she is no longer able to browse or navigate the site.
Even if she tries to Choose a file, or manually type in a web page
URL into the address bar. The little "C" icon in the top-right is
spinning but it's not responding. If the user pulls up IE the site
comes up fine. When she closes and re-opens Contribute it usually
fixes it and works for a while. At last communication, it wasn't
working at all even after a restart. I personally noticed this
issue on my computer when I was at her location. I have other users
connected the same way at different locations, but so far no
reports from them. Any ideas at all?

It's not about "like" or "not like", it's about following
common code of conduct of
this forum specified by the posting guidelines, to which by
the way you agreed upon
singing up in here.
Secondly, regardless your personal feeling on the topic, it
simply works against you
whether you like it or not. Regular forum participants will
ignore bumped posts,
bottom line just to prove that pushing your way while others
wait nicely in the queue
is plain rude. All posts are equally impotent and equally
urgent, it's rather arrogant
to climb your way back just so you can get answer faster.
So go ahead, bump away...tho, don't ***** about no body
entertaining your questions
but before you do that, familiarize yourself with posting
guidelines and general forum
ethics.

Strange Problem about KeyListener, and FocusListener

Hi,Please help me with this problem.
I create a JTable and setCellEditor by using my customerized TextField
The problem is: when I edit JTable Cell, the value can not be changed and I can not get Key Event and Focus Event.
here is my source:
//create normal JTable instance,and then initlize it
private void initTable(Vector folders)
TableColumn tempcol = getColumnModel().getColumn(0);
tempcol.setCellEditor(new DefaultCellEditor(new MyTextField()));
for(int i=0;i<folders.size();i++)
mddDataSource ds=(mddDataSource) folders.get(i);
String name = ds.getDataSourceName();
layers.add(name);
for(int i=0;i<layers.size();i++){
Vector temp = new Vector();
temp.add(layers.get(i));
temp.add(layers.get(i));
dtm.addRow(temp);
// My Text Field cell
class MyTextField extends JTextField implements FocusListener, KeyListener
MyTextField()
setOpaque (false);
addKeyListener(this);
addFocusListener(this);
MyTextField(String text)
setOpaque (false);
addKeyListener(this);
addFocusListener(this);
public void focusGained(FocusEvent e) {
System.out.println("get Focus");
public void focusLost(FocusEvent e) {
instance.setValue(getText());
public void keyTyped(KeyEvent e){
instance.setValue(getText());
public void keyPressed(KeyEvent e){
System.out.println("get Key ");
public void keyReleased(KeyEvent e){
instance.setValue(getText());
If there are some good sample, please tell me the link or give me some suggestion.
Thanks in advanced

Thanks for your help.
The problem still exist. It does not commit the value that I input.
Maybe I should say it clearly.
I have create JPanel include three JPanel:
Left Panel and right upper-panel and right borrom panel.
The JTable instance is on right-upper Panel.
If I edit one of row at JTable and then click JTable other row,the value can be commited. if I edit one of row and then push one Button on
the right-bottom button to see the editting cell value.It does not commit value.
when I use debug style, and set breakpoint the
foucsGained or KeyTyped,
It never stopes at there,So I assume that the Editing cell never get focus.
Is there a bug at Java if we move focus on other Panel, that JTable can not detect the Focus lost or focus gained event?
Thanks

So I use XMLSpy to simulate XI to send SOAP request to legacy system, it works fine.In XI, I use WSDL file which legacy system provided to build the mapping, so I think it should be fine. Please comments, thank you for your time.

Hi
For receiver webservice you need to configure a receiver soap adapter

Hi,

Strange Problem about Dom Parser

Hi, all
I am using Dom parser to extract content from one xml file, and it works this afternoon, then tonight when i tried to run again, it gives me an exception:
org.xml.sax.SAXParseException: Document root element "Total", must match DOCTYPE root "null".
In my xml file, i don't have <!DOCTYPE ....>, but it is the same xml file i run this afternoon, also, as far as i know, <!DOCTYPE> is not necessary, right?
Please help me, really frustrated here!

The parser class only supports a class derived from the java.io.Reader class. I am not sure if there is a class that derives from such that would handle a url string. You may need to obtain the file using java.net for the url and then pass that to a FileReader object.
One thing that i just thought of that might work is this:
parser.parse(new File(url));
