BPM: Loop condition not coming outside of the loop

Hi Experts,
I am working on BPM. In the loop I am giving the condition as
(ForSyncResponse./p1:MT_Test_JDBC_Req_response/row_response/Row/indicator u2260 9)
If indication not equal to the 9(Integer) then it should come out of the loop otherwise loop needs to be repeat( Iam getting this data from the database through Send Synch step). When ever iam sending data other than 9 then it repeating if I send 9 also even though the loop condition is not satisfying and its keep on repeating the loop. Can you please let me know what might be ther problem.
Thanks & Regards,
Purushotham

Hi Prasadh,
         I am able to give thie "Create the following expression in the expression editor:
/MT_Test_JDBC_Req_response/row_responseindicator != 9" expression
           How can i give the second"(/MT_Test_JDBC_Req_response/row_responseindicator != 9 EX)" condition??
          I tried with giving the AND but it is not allowing me to enter the 9.
     Can you please let me know.
Thanks & Regards,

BPM Loop Condition ?

We have a output xml in BPM as shown below :
<?xml version="1.0" encoding="utf-8" ?>

</Category>
</ProductRecord>
</Product>
The product id tag is 1..undbounded.
We want a loop condition in BPM wherein as soon as we get a line of ProductID with   schemeID="ProductGUID" then we want to exit the loop.
Can anybody help us with the loop condition.

I pull fiftyfour bytes of data from MicroProcessor's EEPROM using serial port. It works fine. I then send a request for 512 bytes and my "read" goes into loop condition, no bytes are delivered and system is lost

I pull fiftyfour bytes of data from MicroProcessor's EEPROM using serial port. It works fine. I then send a request for 512 bytes and my "read" goes into loop condition, no bytes are delivered and system is lost

Hello,
You mention that you send a string to the microprocessor that tells it how many bytes to send. Instead of requesting 512 bytes, try reading 10 times and only requesting about 50 bytes at a time.
If that doesn�t help, try directly communicating with your microprocessor through HyperTerminal. If you are not on a Windows system, please let me know. Also, if you are using an NI serial board instead of your computer�s serial port, let me know.
In Windows XP, go to Start, Programs, Accessories, Communications, and select HyperTerminal.
Enter a name for the connection and click OK.
In the next pop-up dialog, choose the COM port you are using to communicate with your device and click OK.
In the final pop
-up dialog, set the communication settings for communicating with your device.
Type the same commands you sent through LabVIEW and observe if you can receive the first 54 bytes you mention. Also observe if data is returned from your 512 byte request or if HyperTerminal just waits.
If you do not receive the 512 byte request through HyperTerminal, your microprocessor is unable to communicate with your computer at a low level. LabVIEW uses the same Windows DLLs as HyperTerminal for serial communication. Double check the instrument user manual for any additional information that may be necessary to communicate.
Please let me know the results from the above test in HyperTerminal. We can then proceed from there.

JMM: legal to optimize non-volatile flag out of particular loop condition?

Does Java Memory Model allow JIT compiler to optimize non-volatile flag out of loop conditions in code like as follows...
class NonVolatileConditionInLoop {
private int number;
private boolean writingReady = true; // non-volatile, always handled inside synchronized block
public synchronized void setNumber(int n) {
    while (!writingReady) { // non-volatile flag in loop condition
      try { wait(); }
      catch (InterruptedException e) { e.printStackTrace(); }
    this.number = n;
    this.writingReady = false;
    notifyAll();
public synchronized int getNumber() {
    while (writingReady) { // non-volatile flag in loop condition
      try { wait(); }
      catch (InterruptedException e) { e.printStackTrace(); }
    this.writingReady = true;
    notifyAll();
    return number;
}...so that it will execute like this:
class NonVolatileConditionInLoopHacked {
private int number;
private boolean writingReady = true; // non-volatile, always handled inside synchronized block
public synchronized void setNumber(int n) {
    if (!writingReady) { // moved out of loop condition
      while (true) {
        try { wait(); }
        catch (InterruptedException e) { e.printStackTrace(); }
    this.number = n;
    this.writingReady = false;
    notifyAll();
public synchronized int getNumber() {
    if (writingReady) { // moved out of loop condition
      while (true) {
        try { wait(); }
        catch (InterruptedException e) { e.printStackTrace(); }
    this.writingReady = true;
    notifyAll();
    return number;
This question was recently discussed in [one of threads|http://forums.sun.com/thread.jspa?messageID=11001801#11001801|thread] at New To Java forum.
My take on it is that optimization like above is legal. From the perspective of single-threaded program, repeated checks for writingReady are redundant because it is not modified within the loop. As far as I understand, unless explicitly forced by volatile modifier (and in our case it is not), optimizing compiler "has a right" to optimize based on single-thread execution assumption.
Opposite opinion is that JMM prohibits such an optimization because methods containing the loop(s) are synchronized.

Opposite opinion is that JMM prohibits such an optimization because methods containing the loop(s) are synchronized.One of the problems with wait() and your the proposed optimization is that "interrupts and spurious wakeups are possible" from wait() . See [http://java.sun.com/javase/6/docs/api/java/lang/Object.html#wait()] Therefore your wait() would loop without checking if this optimization would occur and a interrupt or spurious wake-up happened. Therefore for this reason I do not believe writingReady would be rolled out of the loop. Also the code isn't even equivalent. Once all the threads wake-up due to the notifyAll() they would spin in the while(true) and wait() again. I don't think the JMM prohibits such an optimization because methods containing the loop(s) are synchronized, but because it contains a wait(). The wait() is kind of a temporary flow control escape out of the loop.
Example:
writingReady is true
Thread A calls getNumber(). It waits().
Thread B calls setNumber(). It calls notifyAll() and writingReady is now false;
Thread A wakes up in getNumber() and while(true) loop and waits again(). //Big problem.

Less or less than equal in the for loop condition

Hi,
What do you prefer, what is more common, which one is more easily readable, less or less than equal in the for loop condition?
for (int i = 0; i < arr.lenght; i++){..}
//or
for (int i = 0; i <= arr.lenght - 1 ; i++){..}I know this is basic programming and nothing to do with Java, so if this forum is not for this purpose, could you please suggest a general programming forum?
I would really appreciate it as I have many general questions :)
Thanks in advance,

Help with a while loop condition

I'm trying to write to a File. I ask the user for input, then I enter a while loop and test the condition. The loop works, but it won't stop. I've tried everything. Here is my code please help!!
thanks
inputline = keyboard.readLine();//read the keyboard
try{
while( inputline != null ){
DiskOut.println( inputline );
DiskOut.flush();
inputline = keyboard.readLine();//read the keyboard again
}//end while
}//end try
catch (IOException e) {
e.printStackTrace();
}//end catch
also i've tried these while loop conditions:
while(inputline != "\n" || inputline != "\r") and the sort

while(inputline != "\n" || inputline != "\r")The condition
X!=Y OR X!=Z (given Y != Z)
is always true. X will always not be equal to at least one of the values. So you'll want to use:
while(!inputline.equals("\n") && !inputline.equals("\r"))In other words, "while inputline is not equal to either of them". Note the use of && instead of ||.
If "keyboard" is simply a BufferedReader on top of System.in (and not your own class), the trailing line feeds and carriage returns won't even be in the string returned by readLine(). Your best bet is this:
while(null != inputline && 0 != inputline.length())Make sure you type the two parts of that AND condition in the order above. If for whatever reason there are trailing \r and \n on the strings, you'll want to accomodate for platforms that may include both characters.
// trim the trailing newline characters
while(inputline.endsWith("\r") ||
inputline.endsWith("\n")) {
inputline = inputline.substring(0,inputline.length()-1);
// or maybe this will work if you don't mind losing
// the whitespace at the beginning of the string:
inputline = inputline.trim();Hope that helps somewhat.

New object inside loop condition

if ((myFile = new File(fileString)).exists()) { ...instead?
Winston1) Same thing I put (except change the name "f" with "myFile")
2) you could get a never-ending loop with your answer (depending on the body)
3) The previous answer by Encephalopathic would NOT give a never-ending loop unless there was a never-ending listing of files with the name:
"Foo" + fileCounter + ".txt"; where "fileCounter" is incrementing (as done in his code)

Endless loop condition

Hi there,
Working on a client/server chat application. On the client side app, everytime I want to send a message I create a new Thread called "SendingThread". See below.
import java.io.*;
import java.net.*;
public class SendingThread extends Thread
private Socket clientSocket;
private String messageToSend;
public SendingThread(Socket socket, String userName, String message)
       super("SendingThread: " + socket);
       clientSocket = socket;
       messageToSend = userName + Constants.MESSAGE_SEPERATOR + message;
public void run()
       try
            PrintWriter writer = new PrintWriter(clientSocket.getOutputStream());
            writer.println(messageToSend);
            writer.flush();
            writer.close();
       catch(IOException ioe)
            System.out.println("Server must have closed connection");
            ioe.printStackTrace();
}As you can see the line writer.close() is important in regard to a Thread that is running on the server app called "ReceivingThread" (see below). In the ReceivingThread there is a line:
if((temp = input.readLine()) != null)
It blocks until I actually send a message to read in. This is expected. However, now I have a catch 22 situation. On the client side app, since I called writer.close(), this was necessary in order to get a null value during the readLine() call on the ReceivingThread on the server. The one line gets processed as expected. The stream is now closed and on the server side app, since this is true, the next iteration of the while loop attempts to read in another line but now it is alway null and thus I wind up with an endless loop condition. I introduced a "count" variable and a condition only so that the loop wouldn't get away too far. I was hoping it would block again, but it isn't. I believe the ReceivingThread is written correctly, but I need to somehow obtain a null value on the stream for message completion and also have the ReceivingThread block for the next message coming in.
Please advise,
Alan

I'm not quite sure what you want to happen here. Here is what I would expect from the code you posted:
*1.* The client connects and sends its message to the server.
*2.* The server iterates through the line-reading loop until it exhausts the input (input.readLine() == null) and breaks out of the while (true) loop. The "temp: foo" messages are written to standard output accordingly.
*3.* The server reaches the message portion of the loop and writes the "message: foo" to standard output.
*4.* The server hits the end of the "while (keepListening)" loop and (assuming that you didn't receive a disconnect message) keepListening is still true. So it loops back around.
*5.* The first time through the while (true) loop, the input is still empty (of course). So you get a null.
*6.* Next, you get a "message: foo" output.
*7.* Repeat *4* through *6* until your computer hardware fails or you abort the program. (Except that you added that count thing, so it'll loop three times and then break.)
What are you trying to make the "keepListening" loop do? It doesn't seem like it should be there at all. At no point does this reading thread get the opportunity to read from any other socket. It almost seems like you want to spawn one ReceivingThread for each Socket you receive from the ServerSocket; if that's the case, the main thread (or whichever thread you have running that code and spawning the ReceivingThreads should be inside of the while (keepListening) loop.
Any help?

If statement on a while loop condition

Hello,
I was just wondering whether it was possible to have an if statement on a while loop. Basically, I have a while loop that has the following terminating condition
do{
//...loop code here
while (netError > acceptableError && learningCycle < 100000 && alive);I'm looking to introduce a boolean "ignoreMaxCycles" that basically stops the loop from taking notice of the learningCycle clause of the condition.
do{
//...loop code here
while (netError > acceptableError && alive);I know it can be done repeating the two loops with an if statement governing which one is executed, but I was wondering whether there was a shorter/cleaner way of doing this?
Thanks,
Nick

While loop and for loop condition terminal

Hello friends,
I am using labview 8.6. The condition terminal of the while loop and conditional for loop is behaving in just the opposite way.
When i wire a true to the condition terminal of my loop, the while loop continues to run when I click on run. when I wire a FALSE, it stops.
Is there any setting change that I have to make it to get it work properly.
Please suggest on this.
Thanks and regards,
Herok

Whatever you are seeing must be due to some corruption or folding error. It all works fine here.
To make sure there are no hidden objects, simply press the cleanup button which would reveal any extra stuff (which is obviously not there). Does it fix itself if you click the termination terminal an even number of times? What if you remove the bad loop and create a new one?
Could it be you have some problems with the graphics card and the icon of the conditional terminal does not update correctly?
Whay happens if you connect a control instead of a diagram constant?
What is different on the computers where it acts incorrectly (different CPU (brand, model), #of cores, etc.)

CcBPM Loop Condition Editor

Hi
I am trying to control the number of iterations of a Loop witihn a ccBPM Integration Process.
I have a Container name: index type: xsd:integer , which is initialised to 0 before the loop is entered.
I also have Container name: InterfaceCount which is an Abstract Interface containing the total number of iterations required.
In the Condition Editor for the Loop, if I put index!=InterfaceCount
... it complains that types xi:operation and xsd:integer cannot be compared.
Would someone be able to tell me the correct way of doing this please?
Thanks in advance.

Hi. Thanks for the reply.
What I need to do is compare index to a value passed in on a field on a message.
Maybe I need to define another integer container, and then use a 'container operation' to extract the interface field to this new integer container, before entering the loop. Then I can compare my 'index' integer with the new one to control the loop?

While loop condition check

Dear All,
attached is an NI that does the following.
1. The user inputs a frequency and amplitude range to drive a speaker.
2. A laser displacement sensor measure the speaker displacement, checks if it is in the desired range, and jumps on to the next frequency, if its not in the desired range it tries another drive voltage.
The program works fine, the problem is, is that the while loop checks the condition in the beginning or the middle of the loop, therefore if it is in range instead of stoping at that particular amplitude and frequency, it goes to the next amplitdue before going to the next frequency. Since at the begining of the loop execution the condition was different that in the middle.
How can I force the while loop to read the condition only after the sequence inside has completed.
Thank you

Editing While Loop Conditions hangs JDeveloper 10.1.3

Hi Guys,
Having a strange problem when I tried to edit the condition in a while loop after it was created and set first time. The IDE just hanged when I tried to open the expression builder and after a while, nothing happened, the expression builder didn't show up.
I went and deleted the condition by editing the source, basically made condition from:
<while name="While_1"
condition="bpws:getVariableData('inputVariable','payload','/client:WhileLoopTesterProcessRequest/client:input')<10">
to
<while name="While_1"
condition="">
Switched back to graphics mode, the expression builder opens up normally.
I understand that we are evaluation a Developers Preview, so just wanted to bring this to the notice of the developers.
Any solutions before the Production release?
