Context Handling problem

Hi all,
I have a problem with a context handling requirement. I think UDF is needed in this case but I don't know where to start. Please see below for the scenario:
I have an input structure like this:
segment1
     field1
segment2
     field2
segment3
     field3
node2
     field2
node3
     field3
node3
     field3
the fields will corelate the segment and the node. so for this structure, segment2 and node2 are corelated. Actually, node2 is under segment2.
here's my desired output to make things clearer:
segment1
     field1
segment2
     field2
     node2
          field2
segment3
     field3
     node3
          field3
     node3
          field3
field1 sample value. ex. 0000000001
all field2 have the same value. Value from both segment2 and node2 of field2 is the same. ex. 0000000002
all field3 have the same value. Value from both segment3 and the 2 node3s of field3 is the same. ex. 0000000003
In my current mapping, I'm getting this erroneous output:
segment1
     field1
     node2
          field2
segment2
     field2
     node3
          field3
segment3
     field3
     node3
          field3
The nodes are not in their correct segments. node2 is one level higher because there was no node1.
Occurrence of segments are 1..unbounded. nodes are 0..unbounded.
Thanks all.

Hello,
You need to use UDF for this:
UDF type is Context
Arguments:
input1
input2
HashMap map = new HashMap();
for(int a=0;a<input2.length;a++){
     if(!map.containsKey(input2[a])){
          map.put(input2[a],"");
for(int a=0;a<input1.length;a++){
     if(map.containsKey(input1[a])){
          result.addValue("true");
     else{
          result.addValue("false");
mapping is something like this:
input1 -> removeContext -> UDF -> target
input2 -> removeContext -> /
Hope this helps,

Context handling problem in output message

Hi Experts,
I have an issue where the context is not properly handled:

The UDF used here takes the length of the input string and divides into multiple of 5 and the remainder into the last E1MTXLM Segment.
Similar logic is implemented in "TDLINE" element
Output IDoc Format:
<E1MTXHM> Segment
    <E1MTXLM> Segment
    <TDLINE> Element
    </TDLINE>
    </E1MTXLM>
</E1MTXHM>

Context handling in message mapping for an IDoc to File Scenario

Hi,
Can somebody help me with this issue. I have an Idoc to file scenario. heres my idoc structure. Its a custom Idoc
Header (1..1)
Detail (0..Unbounded)
         DependentDetail (0...Unbounded)              Note: This dependentdetail is a subelement of Detail
Trailer(1...1)
I created my target structrure the same way as the Idoc structure.
My output is a simple text file. I need the output in this format
Header
Detail1
   Dependentdetail1
   DependentDetail2
   DependentDetail3
Detail2
   DependentDetail1
   Dependentdetail2
Detail3
Detail4
Trailer
Since the Detail and Dependent Detail records are unbounded .
But right now i m getting my output like this:
Header
Detail1
Detail2
Detail3
Detail4
Trailer
But the DependentDetail record in not showing up in the output file. I didnot do any context change in my mapping. So do I need to do any context handling??...If so can somebody explain me with this.
Thanks,
Adam

Thanks Kenneth foryour quick reply,
Yes, I see the payload for Dependent detail in SXMB_MONI. So as you said earlier there's a problem with my content conversion.
my content conversion is as follows:
Header.fieldNames
Header.fieldFixedLengths
Header.endSeparator
Detail.fieldNames
Detail.fieldFixedLengths
Detail.endSeparator
DependentDetail.fieldNames
DependentDetail.fieldFixedLengths
DependentDetail.endSeparator
Trailer.fieldNames
Trailer.fieldFixedLengths
Trailer.endSeparator
So As I told earlier. With the above content conversion. I am not able to get the Dependent detail record in my output file. So If there is a change in my content conversion can u check it and tell me where I went wrong.
Thanks,
Harsh

Context handling during message mapping

Hi,
I'm working on a mapping and it almost works. There is just 1 thing to solve. I use the fixvalues funtion with as input a field A in a segment of my Idoc. This function is used to map a field B in another segment. However as this segment has multiple occurences, I have problems with the context handling: the first timle works ok but then it fails (as the filed A is in another segment/context). How could I fix this? I would like to avoid UDF as I don't know much java.
Kind regards,
Ulrich

Hi Ulrich,
<b>Mapping A_source-Fixvalue-B_target</b>
In the above case What are the elements exist in A_Source same thing will be transfered to B_target . If it is not find any value in Fixvalue table then it will pass the default value. So provde the default value.
If there is not element in context then it won't create b_target not at all for that context. So use the Mapwithdefault() nodefunction before passing the value B_target. so in that case it will generate the empty value instead of none.
Warm Regards,
Vijay

Exception Handling Problem In BPM

All
I am facing an exception handling problem I am using BPM and , I have caught exception in the transformation step but when there is any data problem in that mapping(mentioned in the transformation)
it is not throwing the exception . is there any option to collect these type of system exception in the bpm and give a alert thru mail
is there any way to collect these type of exception happened in the BPE and raise alert thru generic alert
Thanks
Jayaraman

Hi Jayaraman,
When you say there is any data problem, does that fail the message mapping that you have defined?
If the message mapping used in the tranformation fails, it should raise an exception in the BPM.
Did you test the message mapping using the payload and see if it really fails or not?

You might need a #

GUI event handling problems appear in 1.4.1 vs. 1.3.1?

Hi,
Has anyone else experienced strange event handling problems when migrating from 1.3.1 to 1.4.1? My GUI applications that make use of Swing's AbstractTableModel suddenly don't track mouse and selection events quickly anymore. Formerly zippy tables are now very unresponsive to user interactions.
I've run the code through JProbe under both 1.3 and 1.4 and see no differences in the profiles, yet the 1.4.1 version is virtually unusable. I had hoped that JProbe would show me that some low-level event-handling related or drawing method was getting wailed on in 1.4, but that was not the case.
My only guess is that the existing installation of 1.3.1 is interfering with the 1.4.1 installation is some way. Any thoughts on that before I trash the 1.3.1 installation (which I'm slightly reluctant to do)?
My platform is Windows XP Pro on a 2GHz P4 with 1GB RAM.
Here's my test case:
import javax.swing.table.AbstractTableModel;
import javax.swing.*;
import java.awt.*;
public class VerySimpleTableModel extends AbstractTableModel
private int d_rows = 0;
private int d_cols = 0;
private String[][] d_data = null;
public VerySimpleTableModel(int rows,int cols)
System.err.println("Creating table of size [" + rows + "," + cols +
d_rows = rows;
d_cols = cols;
d_data = new String[d_rows][d_cols];
int r = 0;
while (r < d_rows){
int c = 0;
while (c < d_cols){
d_data[r][c] = new String("[" + r + "," + c + "]");
c++;
r++;
System.err.println("Done.");
public int getRowCount()
return d_rows;
public int getColumnCount()
return d_cols;
public Object getValueAt(int rowIndex, int columnIndex)
return d_data[rowIndex][columnIndex];
public static void main(String[] args)
System.err.println( "1.4..." );
JFrame window = new JFrame();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
Dimension size = new Dimension(500,500);
panel.setMinimumSize(size);
panel.setMaximumSize(size);
JTable table = new JTable(new VerySimpleTableModel(40,5));
panel.add(table);
window.getContentPane().add(panel);
window.setSize(new Dimension(600,800));
window.validate();
window.setVisible(true);
Thanks in advance!!

Hi,
I've fixed the problem by upgrading to 1.4.1_02. I was on 1.4.1_01.
I did further narrow down the symptoms more. It seemed the further the distance from the previous mouse click, the longer it would take for the table row to highlight. So, clicking on row 1, then 2, was much faster than clicking on row 1, then row 40.
If no one else has seen this problem -- good! I wouldn't wish the tremendous waste of time I've had on anyone!

Labview slider event handling problems - revisited

This topic asked a question that was very close to a problem I am having:
Labview slider event handling problems
That is, how do I, using an event structure and/or other means, only read out the value of a slider control after the value change is finalized?
The extra constraint I'd like to place on this, which I believe will invalidate the answer given in the thread above, is that my slider control also has a digital display which can also be used to change the value without ever using the mouse. I cannot look for a value change followed by a mouse-up event if the mouse was not used to change the value.
Any ideas how this might be accomplished? FWIW, I am using LabVIEW 7.0

Each and every incremental value-change event generated by the movement of the slider is still detected and queued up for use by the event structure and the event structure loop wades through them all before it's done.
I have come up the attached "fix" (LV v7.0) for this problem. While it is not as clean a solution as I had hoped it would be, it's the best I can manage given what LabVIEW offers me to work with and it does work in the situation where I need to use it.
Now, within the Finalize Slider Events subVI, I'm keeping track of the most-recent values seen by the subVI, checking to see if they have changed, and reporting out that fact. That gives me a Changed/Not-Changed bit within the event case that I can use to control what code then gets executed. If the event case is just playing catch-up to the real value of the control, I can now see that fact and ignore it.
In this version I've also dumped the variant output and limited the VI to using DBL values. I decided it added complication to something that was too complicated already and I wanted the output terminals for other purposes anyway (reporting of the correct "OldVal" of the control).Message Edited by Warren Massey on 04-28-2005 03:56 AM

Delicate ProgressMonitor/ event handling problem

Hi,
I have a delicate ProgressMonitor / event handling problem.
There exists some solution on similiar problems here in the forums, but no solution to my special problem, hope anybody can help me out.
I have a rather big project, an applet, that I've written a separate JarLoader class that will load specific jar's if the ClassLoader encounter a unloaded class, all ok so far.
But, during loading, I would like to display a ProgressBar. And here is the problem. If my custom ClassLoader intercepts a findClass -request that needs to load the class from a jar from a normal thread, this is no problem, but if the ClassLoader intercepts a findClass that needs loading a jar when inside the EventQueue -thread, this is becomming tricky!
The catch is that an event posted on the EventQueue finally needs a class that needs to be loaded, but I cannot dispatch a thread to do this and end that particular event before the class itself is loaded.
So how do I hold the current EventQueue -event needing a jar -load, Pop up a ProgressBar, then process events in the EventQueue to display the ProgressBar and update repaints in it? then return from the event that now have loaded needed class-files.
I've tried a tip described earlier in the forums by trying to handle events with this code when loading the Jar:
    /** process any waiting events - use during long operations
     * to update UI */
    static public void doEvents() {
        // need to derive from EventQueue otherwise
        // don't have access to protected method dispatchEvent()
        class EvtQueue extends java.awt.EventQueue {
            public void doEvents() {
                Toolkit toolKit = Toolkit.getDefaultToolkit();
                EventQueue evtQueue = toolKit.getSystemEventQueue();
                // loop whilst there are events to process
                while (evtQueue.peekEvent() != null) {
                    try {
                        // if there are then get the event
                        AWTEvent evt = evtQueue.getNextEvent();
                        // and dispatch it
                        super.dispatchEvent(evt);
                    catch (java.lang.InterruptedException e) {
                        // if we get an exception in getNextEvent()
                        // do nothing
        // create an instance of our new class
        EvtQueue evtQueue = new EvtQueue();
        // and call the doEvents method to process the events.
        evtQueue.doEvents();
    }Then, the loader checks
java.awt.EventQueue.isDispatchThread()to see if its' inside the eventqueue, and runs doEvents after updating the ProgressMonitor with new setProgress and setNote values.
More precise;
The loader is loading the jar like this:
(this is pseudo code, not really usable, but outlines the vital parts)
public void load() {
monitor = new ProgressMonitor(null, "Loading " + jarName, ""+jarSize + " bytes", 0, jarSize);
monitor.setMillisToDecideToPopup(0);
monitor.setMillisToPopup(0);
// reading jar info code here ...
JarEntry zip = input.getNextJarEntry();
for (;zip != null;) {
     // misc file handling here... total = current bytes read
     monitor.setProgress(total);
     monitor.setNote(note);
     if (java.awt.EventQueue.isDispatchThread()) {
        doEvents();
     zip = input.getNextJarEntry();
monitor.close();
}When debugging doEvents(), there is never any events pending in peekEvents(), even if I tries to put a invokeLater() to run the setProgress on the monitor, why? If it had worked, the doEvents() code would have saved my day...
So, this is where I'm totally stuck...

Just want to describe how I did this using spin from http://spin.sourceforge.net
This example is not pretty, but it can probably help others understanding spin. Cancelling the ProgressMonitor is not implemented, but can easily be done by checking on ProgressMonitor.isCanceled() in
the implementation code.
First, I create a bean for displaying and run a ProgressMonitor:
Spin requires an Interface and an Implementation, but that's just nice programming practice :-)
import java.util.*;
public interface ProgressMonitorBean {
    public void start(); // start spinning
    public void cancel(); // cancel
    public int getProgress(); // get the current progress value
    public void setProgress(int progress); // set progress value
    public void addObserver(Observer observer); // observer on the progressValue
}Then, I created the implementation:
import java.util.*;
import javax.swing.ProgressMonitor;
import java.awt.*;
public class ProgressMonitorBeanImpl extends Observable implements ProgressMonitorBean {
    private ProgressMonitor monitor;
    private boolean cancelled;
    private int progress = 0;
    private int currentprogress = 0;
    public ProgressMonitorBeanImpl(Component parent, Object message, String note, int min, int max) {
        monitor = new ProgressMonitor(parent, message, note, min, max);
        monitor.setMillisToDecideToPopup(0);
        monitor.setMillisToPopup(0);
    public void cancel() {
        monitor.close();
    public void start() {
        cancelled = false;
        progress = 0;
        currentprogress = 0;
        while (progress < m_cMonitor.getMaximum()) {
            try {
                synchronized (this) {
                    wait(50); // Spinning with 50 ms delay
                if (progress != currentprogress) { // change only when different from previous value
                    setChanged();
                    notifyObservers(new Integer(progress));
                    monitor.setProgress(progress);
                    currentprogress = progress;
            } catch (InterruptedException ex) {
                // ignore
            if (cancelled) {
                break;
    public int getProgress() {
        return progress;
    public void setProgress(int progress) {
        this.progress = progress;
}in my class/jarloader code, something like this is done:
public void load() {
ProgressMonitorBean monitor = (ProgressMonitorBean)Spin.off(new ProgressMonitorBeanImpl(null, "Loading " + url,"", 0, jarSize));
Thread t = new Thread() {
    public void run() {
      JarEntry zip = input.getNextJarEntry();
      for (;zip != null;) {
        // misc file handling here... progress = current bytes read
     monitor.setProgress(progress);
t.start(); // fire off loadin into own thread to do time consuming work
monitor.start(); // this will spin events on monitor and block until progress = max
monitor.cancel(); // Just make sure ProgressMonitor is closed
}The beautiful thing here is that Spin is taking care of weither the load() is inside the dispatch thread or not, making the code much simpler and cleaner to understand.
The ProgressMonitorBeanImplementation could been made much nicer and more complete, but I was in a hurry to check if it worked out. And it did! This will be applied on a lot of gui -components that blocks the event-queue in our project, making it much more responsive.
Hope this will help others in similiar situations! Thanks again svenmeier for pointing me to the spin -project.

Mapping problem in context handling

Hi experts,
               I am doing a file to file scenario in which i have to change the queue context is it possible? for simple context change we use ResultList.CC in advance UDF but what to do if we want to add a queue cahnge .To dig more deep into the problem i am explaining my scenario.
my output structure is <GROUP> .....(1 to unbounded)
                                    <Records>....(1 to unbounded)

Hi,
context object is a generic term used to make a reference to message heder fileds in the XML file (also vth XPATH). Context of an element is nothing but just the level (with reference to its parent node) where the XML tag appears in the given XML document.

Idoc Segment - Context Handling.

Hi All,
Can anyone suggest me a solution as how to handle the below idoc context problem.. its a file to idoc scenario
I have an Debmas idoc, in which It is possible for a customer to have more than one E1KNBKM segment, so we only want to map the first segment for that customer and then also we only want the information from the /GLB/XGT_EXTRA_17 segments that are child segments of E1KNBKM.
-Anu

What Ravi suggested was:
SourceNode --> Index -->
--> equalS --> ifWithoutElse (Then SourceNode) --> TargetNode
Constant(1) -->
Index is similar to Count function (just that it is more reliabel when counting multiple node occurences)...the above will check if the occurence of SourceNode isthe first or not.
Regards,
Abhishek.

Noticed some issues with how NI DNET card handles problems

We have
noticed 2 issues with using the PXI NI-DNET (PXI-8461) card and Labview (8.5).
1. The scanner doesn’t recover from a lost of
DNET power
- With network
work up and everything scanning
- The Dnet
DC power is turned off and then turned back on
- All nodes are rest from the power cycle which
is common
- However,
when we try to scan the network again, Labview faults with can’t initialize card
I believe
- No nodes
restart
The DNET
card seems to not be monitoring the network DC power and releasing the handles
and/or trying to rescan the attached nodes.
Work
around: Restart the PXI or in Max, remove and reinstall DNET card
The work around are not a good solution. Is there another solution and why isn't the card restarting.
2. When Labview locks up, the DNET card keeps
scanning. When this happens the last
setpoints are still being sent. This can
be a problem if a heating is being controlled.
No work around
Is there any watch dog for this issue?

Howdy Olaje,
I think I've found a solution for your first question. Take a look at this Discussion Forum and see if it does the trick. However, I need a bit more information about your second question. I'm curious about the specifics of how LabVIEW "locks up". Is this a permanent crash or does it just freeze for a few minutes while control is transfered to another process? Also, what is the context of the lock up? Thanks for answering these follow up questions, I look forward to the response!
Sincerely,

Request.getParameter(): special character handling problem

Hello, there:
This should be an easy question for the gurus in here.
I use a string attached to the url as the parameter string, which includes spaces. the system automatically converts them to %20, but when I receive them in my servlet using request.getParameter, a special character, Â appears; I couldn't proceed with it.
I suppose this is a common problem but seems that I didn't find topics about it on this forum.
So anyone can help? Any encoder/decoder APIs to handle it?
Thanks a lot,
Sway

and use request.getParameter("value");
