Catch of CONVT_NO_NUMBER does not work on 4.6c?

Hi Guys,
I'm having a strange problem. We have a 4.6C system here, an I have the following code:
DATA: h_sub   TYPE n.
DATA: h_part3 TYPE string.
CATCH SYSTEM-EXCEPTIONS convt_no_number = 1.
IF h_part3 > h_sub.
   h_sub = h_part3.
ENDIF.
ENDCATCH.
IF sy-subrc = 1.
   ADD 1 TO h_sub.
ENDIF.
So in cases that variable h_part3 does not contain a number the statement "IF h_part3 > h_sub." raises a CONVT_NO_NUMBER-exception. Strange thing now: My catch-mechanism does not work! I still get a short dump!
Any idea what went wrong?
Thanks and regards
Jan Hempel

I found the reason for this behaviour: it seems like that the if-statement ("IF h_part3 > h_sub") does not have its own conversion-functionality.
I changed my code by adding an explicit move-statement before the if-clause and that does the trick:
      CATCH SYSTEM-EXCEPTIONS convt_no_number = 1.
        MOVE h_part3 TO h_number.
      ENDCATCH.
      IF sy-subrc = 1.
        ADD 1 TO h_sub.
      ELSE.
        IF h_number > h_sub.
          h_sub = h_number.
        ENDIF.
      ENDIF.

Open a view twice does not work

Hello,
I have a problem with bsp-views:
I open a new window via the JavaScript command
<script type="text/javascript" language="javascript">
open( "<%= controller->mv_srch_url%>",
        "searchTask", "resizable=no, scrollbars=no,
         status=yes, menubar=no, width=320, height=522,
         top=50, left=50" );
</script>
If I close this window via the 'X' on the upper right corner of the window and want to open the popup again it doesn't work. This JavaScript command passes correctly but no window is opened.
If I close the popup via a button where a submit is made to the calling (parent) document and open it again, everything works fine.
Now I have two questions:
1. Does anybody have an idea why the popup cannot be opened again?
2. If not, I would like to make a submit if the popup is closed by the 'X'. I tried this in my bsp-view:
<script language="javascript">
        function do_submit(){
        var theForm = window.opener.document.getElementById("theForm");
           theForm.submit();}
        window.onUnload = do_submit
</script>
but it did not work.
I would be very grateful for any help.
Best regards,
Ralph

Catching the 'X' does not work, but opening the popup twice is working. I used the following coding:
open( "<%= controller->mv_srch_url%>",
        "searchTask<%=sy-uzeit>", "resizable=no, scrollbars=no,
         status=yes, menubar=no, width=320, height=522,
         top=50, left=50" );

Ralph
try the following...
1) create a new parameter or variable named callPopup (type CHAR01) with a default value 'N'.
2) then in your view put the following;
<% IF callPopup = 'S'. callPopup = 'N'. %>
<script type="text/javascript" language="javascript">
open( "<%= controller->mv_srch_url%>",
"searchTask", "resizable=no, scrollbars=no,
status=yes, menubar=no, width=320, height=522,
top=50, left=50" );
</script>
<% ENDIF. %>
3) Then when the user press the button to search (or the event to call the popup) just put the value of this variable to 'S'.
Try it...

Help with util.zip up files... does not work

I am writing a program so my mum can zip up new photos she takes and then send them to me. The program creates a html file for the webpage plus a smaller version of her original photo and places them all in a 1 folder with a new name. Al this part works... I want to afterwards place my files in a zipped up folder that she can e-mail me with her normal client. How... I picked up this code on the net and have changed it to incoporate my parameters. The files which are created ..paths are (String in an String[]) I then send to my zipping method.
The zip file is created but does not work when I try to extract from it ??? I also know that the String [] works becuse I have made a loop to check its properties at each index.
what am I doing wrong?
This is a modified code I found on the internet but with no author??
import java.io.File;
import java.io.FileInputStream;

public class Test{

    public Test(String[] recivedFilename){
        filename = recivedFilename;
        try {
            ZipOutputStream zos = new
                    ZipOutputStream(new FileOutputStream("c:\\curDir.zip"));
            from,
            zipDir("c:\\batviapictures\\", zos);
            zos.close();
        } catch(Exception e) {
            //handle exception
    public void zipDir(String dir2zip, ZipOutputStream zos) {
        try {File
            zipDir = new File(dir2zip);
            String[] dirList = filename;
            byte[] readBuffer = new byte[2156];
            int bytesIn = 0;
            //loop through dirList, and zip the files
            for(int i=0; i<dirList.length; i++) {
                File f = new File(zipDir, dirList);
if(f.isDirectory()) {
String filePath = f.getPath();
zipDir(filePath, zos);
continue;
FileInputStream fis = new FileInputStream(f);
ZipEntry anEntry = new ZipEntry(f.getPath());
zos.putNextEntry(anEntry);
while((bytesIn = fis.read(readBuffer)) != -1) {
zos.write(readBuffer, 0, bytesIn);
fis.close();
catch(Exception e) {

I make no guarantees that this will completely solve all your problems, but I just know these calls are needed but missing from your OP:
try {
    ZipOutputStream zos = new
                    ZipOutputStream(new FileOutputStream("c:\\curDir.zip"));
                    from,
                    zipDir("c:\\batviapictures\\", zos);
    zos.flush(); // ADD THIS after all files have been written to the zos
    zos.close();
} catch(Exception e) {
    //handle exception
}And
while((bytesIn = fis.read(readBuffer)) != -1) {
    zos.write(readBuffer, 0, bytesIn);
zos.closeEntry(); // ADD THIS after each file is written to the zos
fis.close();

Applet does not work with a proxy server.URgent

Hi,
I have an asp page being hosted from a IIS server.
The asp page has an applet which gets data from a server side component which is hosted as a service on the server side.For connection to the server I am using URLConnection object and trying to connect over a TCP connection.
The problem occurs when I use an proxy in the middle.
I have changed the browser settings to include the proxy.
The following is the error I recieve:
Full :http://172.25.11.63:4590/

The exact place where I get the error is whn i call URLConnection.openInputStream().
Usually this error comes with a malformed URL.But the same code words without a proxy.Also I am not making any changes to my code in both scenarios that is with or without proxy.
Please help.This is urgent and a showstopper

Thanks for your nice solution, but unfortunatelly it does not work with lines longer than 100 chars with Netscape. It works fine with IE and appletviewer too.
Example:
I use this code:
try {
            URL url = new URL(protocol,hostName,portNumber,URLstring);
            InputStream in = url.openStream();
            BufferedInputStream bis = new BufferedInputStream(in);
            StringBuffer input = new StringBuffer(60);
            int c;
            while ((c = bis.read()) != -1){
                System.out.print((char)c);
                input.append((char)c);
            bis.close();
            dataFromServer = input.toString();
        catch(Exception ex) {
            ex.printStackTrace();
        }I use input file test.html with exactly 100 chars ('a')

JasperReports does not work outside Netbeans

Hi guys,
Background story: application with a couple of forms, the data can be stored and saved from a sqlite database. In the end the forms need to be saved as a PDF.
Netbeans 6.7, JasperReports 4.0.2.
Libraries in my Classpath: Commons-beanutils, Commons collections, commons digester, commons javaflow, commons logging, iText, Jasperreports
I tried to use JasperReports for this matter. It runs perfectly when in Netbeans, and my PDF is generated.
However, when I try to run the compiled .jar file from windows explorer... the whole JasperReports part does not work at all.
I made a simple example showing my problem. It produces a nice 1 line PDF when in netbeans, but outside Netbeans, nothing again.
Could you give me some advice on this? Or maybe an alternative for JasperReports?
Thanks alot,
Elwin

This.print(pp) with interactive type silent or automatic does not work after upgrade acrobat reader 9 to acrobat reader 11

After an upgrade of acrobat reader 9 to acrobat reader 11 the automatic printing of a pdf. The pdf is opened, but the print does not happen. With acrobat reader 9 it works. But with acrobat reader 11 the printing does not happen.
I discovered when you specify pp.constants.interactionLevel.full it works on acrobat reader 11. But when you specify pp.constants.interactionLevel.silent or pp.constants.interactionLevel.automatic it does not work on acrobat reader 11. But with the full option we have a dialog print box
we do not want.
In our jsp we load a pdf document and create a message handler to detect the print events of a pdf document that is in an <object> tag.
In the pdf document we add

From the JS API Reference of the print method:
Non-interactive printing can only be executed during batch, console, and menu
events.
Outside of batch, console, and menu events, the values of bUI and of interactive are ignored
and a print dialog box will always be presented.

Threads does not work correctly

The follow program working with threads. We have two classses : Producer and Customer which working with the same object (which type is class Q). Producer produces data. Customer should capture the data. The Q class must be synchronized. But code does not work (compile under NetBeans 6.0)
class Q {
int number = 0;
boolean filled = false;

System.out.println("Put : " + number);

I.e. i am waiting for the follow result:
1. pr thread starts with common_obj object
2. cs thread starts with common_obj object
3. pr thread tries call common_obj.put(i++) in infinite cycle:
3.1 these lines does not work because filled now is set to false
        while (filled){
            try {
                wait();
            catch(InterruptedException e) {
                System.out.println("Interrupted");
        }3.2 the follow code will be implemented:
        number = n;    // put value to number
        System.out.println("Put : " + number); // output result to console
        filled = true; // value was put. It can be got.
        notify(); // notify another thread (cs) that it should not waiting anymore.4. pr thread tries call common_obj.get() in infinite cycle:
4.1 the following code will not be implemented anymore:
        while (!filled) {
            try {
                wait();
            catch(InterruptedException e) {

        } since another thread notify current.
4.2 the follow code will be implemented:
        System.out.println("Got : " + number);
        filled = false;
        notify();So the result of running this program should be:

BUG: Oracle Schema Processor does not work in Servlets

We found a bug with Oracle's Schema Processor. It does not work in Servlets.
When we try to validate a XML document in a Servlet it does not work, but we can execute the same code in a stand alone application and it works.
The following is the code we are using:
try {
File f =new File(filename);
FileReader r = new FileReader(f);
DOMParser dp = new DOMParser();
URL url = createURL (filename);
dp.setValidationMode(false);
dp.setSchemaValidationMode(true);
dp.setPreserveWhitespace(true);
dp.parse(url);
System.out.println("it is parsed");
} catch(Exception e){System.out.println("there is Error"+e.getMessage());}
null

I don't think this is related to Servlets per se.
Check that the Schema processor classes used by the servlet container, and your application are the same.
Java does not have proper versioning of classes, I have seen many applications collapse. People compiled their code on developer machines, where it worked fine, but when moved to a production machine they failed because the production machine had a different version of classes. Usually the name of the class doesn't change, but either a method or a variable is missing in several classes. VM doesn't complain but simply crashes.
In your Schema Processor classes that are used by the servlet engine might be different from the one that the app uses. Do a search on the file system to see how many copy of the same class bundle (zip, jar) you have on the system.

As a suggestion I'd put the Text_io segments into their own begin - exception - end sub-blocks within the main code. This way if Text_io does raise an exception you can catch it earlier as it may be able to recover - That is if it is a text_io exception.
Other than that you;ll have to step through in Debug.

This program is well compiled but does not work.

I would like to know why this program does not work properly:
the idea is :
1. the user introduces a text as a string
2.the progam creates a file (with a FileOutputStream)
3. then this file is encripted according to DES (using JCE, cipheroutputStream)
4.the new filw is an encripte file, whose content is introduced in a string (with a FileInputStream)
(gives no probles of compilation!!)
(don know why it does not work)

If you don't require your code to run as an applet, you will probably get more mileage from refactoring it to run as an application.
As sudha_mp implied, an unsigned applet will fail on the line
FileInputStream fe=new FileInputStream("c:/javasoft/t.txt");
due to security restrictions. (Which, incidentally, are there for a very good reason)

Reading message from MQ- works in WSAD (IDE) but does not work outside WSAD

Read from MQ:
Same code works within WASD but does not work outside WSAD.

PDL - thanks for the suggestions - here are the results:
A button on the form that executes "this.print();" works fine.
Changing "this" to "event.target" results in the same error.
document.getElementById("PDFObj").Print(); works fine.
However, the reason that I'm using ".postMessage([message])" instead of ".Print()" is because I actually have a toolbar that has save, print, zoom in, zoom out, page up, page down, etc.... I simplified the switch statement in the post above to only include print, but in reality has a case for each of the functions above. The postMessage call is triggering the error, since the catch statement is printing out the error message above. Any idea why this would work with Professional but not Reader.

Maxl iferror goto does not work

Hi,
I have a vbscript which updates substitution variables in essbase.
But if there is an error, for example, if the variable name is different in essbase than what is defined in the script, the script continues to run.
the only time is actually catches an error is when it encounters the error in the last statement that is executed. i tried to put iferror goto, but it does not work either.
Please help.
Below is a portion of my script.
Thanks.
objOutputStream.writeline("login " & Username & " identified by " & password & " on " & Server &";")
objOutputStream.writeline("spool on to "& logfile &";")
objOutputStream.WriteLine("alter database " & APPname & "." & DBname & " set variable abcd " & strabcd &";")
objOutputStream.WriteLine ("iferror goto exit;")
objOutputStream.WriteLine("alter database " & APPname & "." & DBname & " set variable xyz" & strxyz &";")
objOutputStream.WriteLine ("iferror goto exit;")
objOutputStream.WriteLine("alter database " & APPname & "." & DBname & " set variable mnop" & strmnop &";")
objOutputStream.WriteLine ("iferror goto exit;")
objOutputStream.writeline("spool off;")
objOutputStream.writeline("logout;")
objOutputStream.WriteLine (":Exit")
objOutputStream.writeline("exit;")
objOutputStream.close

Hi,
we work with the exit label as follows:
alter database ...
iferror getmeout;
alter database ...
iferror getmeout...
define label "getmeout";
spool off;
logout;
EXIT;
the spool off and logout command should be part of the defined lable (in your case, too), otherwise you wouldnt logout your session if an error occurs.
Kind regards
André

URLLoader does not work

I am following the URLLoader example
I'm compiling with -mxmlc -use-network=false Main.as
Both main.swf and the file I'm trying to download (test.txt) reside in the same directory
I get the open even then the HTTPStatus event (status == 0) then nothing happens
I verified that the file is found: I changed the file name to xtest.txt and promptly got an ioError event.
I tried to compile without -use-network=false and the load failed with an error #2148 as expected
I changed the url to http://test.txt, compiled with -use-naetwork=flase and the load failed with error #2028 as expected
I added a timer to make sure the flash is running, and it does
In short I think it simply is broked!
Compiled using flex sdk "Version 3.3.0 build 4852"
The player's about sends me to http://www.adobe.com/software/flash/about/ , which reports "You have version 10,0,32,18 installed"

            dispatcher.addEventListener(Event.COMPLETE,downloadCompletedHandler);
            dispatcher.addEventListener(Event.OPEN,downloadStartedHandler);
            dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR,downloadSecurityErrorHandle r);

        private function downloadStartedHandler(event:Event):void
            downloadStarted = true;
            statusText += "Started " + event;
        private function downloadCompletedHandler():void
            downloadDone = true;
            statusText += "Completed ";
        private function downloadSecurityErrorHandler(event:Event):void
            statusText += "SecurityError (" + event + ")";
        private function downloadHttpStatusHandler(event:Event):void
            statusText += "HttpStatus(" + event + ")";
        private function downloadIOErrorHandler(event:Event):void
            statusText += "IOError (" + event + ")";

silly mistake... notice how all callback functions take an argument "event"Event" ... all that is _except_ the downloadCompleted handler
i changed
private function downloadCompletedHandler():void
to
private function downloadCompletedHandler(event:Event):void
and this code started to work
unfortunatly, the compiler does not catch this sort of error.

DoClick does not work!!!

For my simple browser I have created a button that allows you to enlarge the size of the text. Now when the page is loaded and you click this button the text size increases as desired.
However I want the text to automatically change to large when the webpage is loaded. So after the setpage method I used largeTxt.doClick() this does not seem to work.
Can you please help me solve this problem, my code is below.
Thanks.

I tried your suggesstions to change the methods as shown below but it still does not work. :(
if (e.getSource().equals(largeText)){
          Thread runner = new Thread() {

               .getDeclaration("font-size:24"), false);
runner.start();
SwingUtilities.invokeLater(runner);
     } // End if
public void DisplayPage(String strURL) {
     currentURL = strURL;
     textURL.setText(strURL);
     //m_btnReload.setToolTipText(strURL);
     try {
          setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
          htmlMain.setPage(strURL);
          SwingUtilities.invokeLater(new Runnable() {
          public void run() {
          largeText.doClick();
     catch (Exception exc) {
               htmlMain.setText("");
               statusBar.setText("Could not open starting page. Using a blank.");
     finally {
     setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
     } //end try
     //largeText.doClick();
}

Catch of CONVT_NO_NUMBER does not work on 4.6c?
