Null pointer Exception on java plug-in , using Mutity language...

hi all :)
I found at plug-in do not suppor Multy language.
for Example...
my operating System is Window XP and log in ID is not English ... like Korean, Chinese etc...
i programmed Web application with Swing Applet(JApplet)... and tested plug-in version 1.2.2 and 1.3.1 and XP plug-in
Plug-in said that like this.
Java(TM) Plug-in: version 1.3.1
JRE version usage 1.3.1 Java HotSpot(TM) Client VM
user home = C:\Documents and Settings\��????��java.lang.NullPointerException java.lang.NullPointerException������ ����:java.lang.NullPointerException������ ����java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException----------------------------------------------------

... etc....
this message is plug-in do not download class archive in client System cache... because of VM cannot know user.home directory...
you can find that java plug-in does not support mulity language to see the next sentence.
"user home = C:\Documents and Settings\��????"
in this reason i found a problem in communication JApplet and java-script by using cookies...
How can I solve this problem...( i must use Multi language login ID plz.....)
have a nice day!!!
poemtry ... ^^

I have such problems with a russian version Windows 2000....

    Hello,
    Java Server Page is a technology that we use to
    generate HTML dynamically and you use scriptlets to
    perform this.
    that's why you are not allowed to use awt or swing
    packages.
    all graphical components have to be an HTML component
    (including applets).
    Najib.Hi,
    I know you are supposed to generate an HTML file, and I'm not creating a JFrame to display it. Let me explain how our application works: when the user presses a button in our page, we have to create a .pdf file and generate a page with a link to it so the user can download it.
    This .pdf file has some charts (the charts and pdf are created with Sitraka's JClass Chart and PageLayout), and in order to embedd the chart in the .pdf file we need to put it first in a JFrame.
    The code snippet is:
    JFrame frame = new JFrame();
    frame.getContentPane().add(chart);
    frame.addNotify();
    Image img = chart.snapshot();
    frame.removeNotify();
    frame.removeAll();
    This works most of the time, but in this specific machine sometimes the instantiation of the JFrame fails with the error I posted before.
    Hope I have made things more clear.

  • Oracle native API for AQ  - Null pointer exception

    Hi

    Error : Exception null
    Please let me know if I missed something.
    Thanks in advance!!!!!

    hi,
    I had found the issue. The queue takes object type messages where as I was trying with Raw messages.
    Instead of AQRawPayload raw_payload = message.getRawPayload();
    I need to use
    AQObjectPayload raw_payload = message.getObjectPayload()
    and pass object as input to the queue.

  • REG : Null Pointer Exception for RFC values

    Hi All,
    I am facing peculiar erro in code.I need to check the null entries in SAP server then it should be replaced by space and if not null then should be replaced by the value in backend.But it is throwing null pointer exception
    I am using equalsignore case(null) and trim for space.
    I am not getting why its is throwing null pointer  exception.Kindly advise
    Regards,
    Anupama

    Hi
    Use
    String f = null ;
    if(f!==null)
    Wdcomponent.getMessageManager.ReportException ("this will cause null pointer exception  "+ f.length());
    Better to give it any Constant like
    priveate static final String NULL_CHECK  = "DEL_VAL12";
    rather than space ,at the time of chceking see if it has  DEL_VAL12 if true then put the actual data else let it be there.

    Hi,
        I am using the Class RetrieveLimitedRecords, to retrieve he records from the main table.
    While using this class I am getting an error Null Pointer Exception, when there are no records matching the search criteriea.
    Could anybody tell me how to ignore this error.

    Hi,
    Thanks for the reply.
        There is no any class which automatically handles, so we should handle exceptions individually.

  • Java Null Pointer Exception while Importing a Table to IS

    Hello All,
    I am trying to import a table into IS and receiving a JAVA Null Pointer Exception. The table is in a Teradata database and I am able to import other tables belonging to the same schema.I get the Java error only while trying to import this one particular table. The DBA has confirmed that the table belongs to the schema/owner I am using. In any case, it seems more of a application error than a database level error. Can anyone provide any insight? Thank you in advance.

    hi Keerthi,
    thank you.
    i tried with below code but still unsuccesfully
         +     oaDFF = (OADescriptiveFlexBean)oawebbean.findIndexedChildRecursive("ActFlexField");+
    oapagecontext.writeDiagnostics(this, "Niccal: i got DFF handle", 1);
    OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
    oapagecontext.writeDiagnostics(this, "Niccal: before if", 1);
    i am able to print 1° comment line but not second. so i think it's something wrong getting the segment handle.
    anyway i'm not able to reach your suggested if statement because execution stops before.
    Infact, if i comment line :OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
    page doesn't give error and saves data.
    any suggestion appreciated,
    thanx,

  • Java Null Pointer Exception- Business Validation In AM

    Hi, I have been tried cracking this validation issue, tried several combinations. But does not work and throw java null pointer exception. I would appreciate if somebody can point where I am going wrong on the code. Thanks ahead.
    Below is the issue:-
    I have a page with PO (blanket purchase order) header info, and a PO line info with additional empty columns (related to Blanket Release). When the user fills in one of the columns (release amount, rls_amt_i), then I need to validate this against remaining blanket amount ie.{ PO_amt - (po_rls_amt1 + po_rls_amt2+..)}. If rls_amt_i is <= remaining amount, then the release needs to get created, otherwise shouldn't. I know, this is a pretty normal requirement. Please check my code to see where I could be wrong.
    ReleaseCO (in PFR):-
    if (pageContext.getParameter("Apply") != null)
    OAApplicationModule am = pageContext.getApplicationModule(webBean);
    OAViewObject vo = (OAViewObject)am.findViewObject("CxPoReleaseVO1");
    Number poHeaderId = (Number)vo.getCurrentRow().getAttribute("PoHeaderId");

    Number lineAmt = (Number)linesVO.getCurrentRow().getAttribute("Amount");
    Serializable [] params = {poHeaderId.toString(), poNumber, lineAmt.toString()};
    am.invokeMethod("apply", params);

    Number blanketAmt, totalreleasesAmt, lineRlsAmt;
    try
    { lineRlsAmt = new Number(lineAmt.trim());}
    catch(Exception e) { throw new OAException("AK", "FWK_TBX_INVALID_EMP_NUMBER"); }
    totalreleasesAmt = getReleasesAmt(poheaderId);
    blanketAmt = getBlanketAmt(poNumber);
    if ((lineRlsAmt.intValue() - (blanketAmt.intValue()-totalreleasesAmt.intValue())) <= 0)
    getTransaction().commit();
    approve();
    throw new OAException("The amount is less than the remaining release amt", OAException.INFORMATION);
    } // end apply()
    public Number getReleasesAmt (String poHeaderId)
    CxTotalReleaseQuantityVVOImpl totalreleaseqtyVO = getCxTotalReleaseQuantityVVO1(); //vo to get TotalReleased Amount
    Number poHeadNum = null;
    Number totalqty;
    try { poHeadNum = new Number(poHeaderId); }

    The code breaks at the line 642: totalqty = (Number)row.getQuantityReleased();
    I had already taken care of the null value in the VO sql query by using nvl(sum(release_amount), 0).. .so it should return atleast 0, if its null. But it returns "null" all the time.
    I dont understand why its doing that. When I run the sql backend the query works fine and returns 0,even when there are no prior releases on the PO.
    Thanks,
    Vikram

  • Null Pointer Exception Error's in WebDynpro Java

    Hi All,
    How Types are coming Null Pointer Exception Error's in WebDynpro Java, Please provide the types.of Errors.
    Ex. Cardinality Type not correct etc...
    Thanks,
    Bye,
    Vijay Hari.

    HI
      Null Pointer Exception can occur in may instances , for suppose
      1) when  you create a Value Node with some attribute which has cardinality , and you have not
      initialized the Node , then it would through  Null Pointer exception ,
      2) when you integrate the RFC and parameters you pass as input to the RFC are not set correctly
          then there could be null pointer when you execute the RFC
      3>or may be when you doesnot bind the node when using webservice then there could be null pointer exception
    and there could be many occurances  for the exception

  • Java Null Pointer Exception - with arraycopy method.

    Hi all,
    I have been trying to fix this for a while now, but I think I've been staring at the screen for too long to fix it!
    Basically I am trying to 'crossover' some arrays (evolutionary technique) but I keep getting a null pointer exception.
    Here is my customised class: class ChromosomeDetails {
         double[] chromosomePrices;
         int[] chromosomePoints;
         int[] chromosomePlayerIDs;
         int chromosomeFitness;
           ChromosomeDetails(double[] chromosomePrices, int[] chromosomePoints, int[] chromosomePlayerIDs, int chromosomeFitness) {
              this.chromosomePrices = chromosomePrices;
              this.chromosomePoints = chromosomePoints;
              this.chromosomePlayerIDs = chromosomePlayerIDs;
              this.chromosomeFitness = chromosomeFitness;     
           public ChromosomeDetails () {  
                chromosomePrices = null;
              chromosomePoints = null;
              chromosomePlayerIDs = null;
              chromosomeFitness = 0;
         public double[] getPrices() {
              return chromosomePrices;
         public int[] getPoints() {
              return chromosomePoints;
         public int[] getPlayerIDs() {
              return chromosomePlayerIDs;
         public int getFitness() {
              return chromosomeFitness;
    }  In my main method I create 2 instances of this class like so:ChromosomeDetails parentChromosomeADetails = new ChromosomeDetails();          
    ChromosomeDetails parentChromosomeBDetails = new ChromosomeDetails();...and 2 other instances that are left empty:ChromosomeDetails childChromosomeCDetails = new ChromosomeDetails();     
    ChromosomeDetails childChromosomeDDetails = new ChromosomeDetails();     I then try to 'crossover' the values in the arrays like so: int randomCrossoverPoint = new Random().nextInt(parentChromosomeADetails.chromosomePoints.length-1);
    System.arraycopy(parentChromosomeADetails.chromosomePrices, 0, childChromosomeCDetails.chromosomePrices, 0, randomCrossoverPoint);
    System.arraycopy(parentChromosomeBDetails.chromosomePrices, randomCrossoverPoint, childChromosomeCDetails.chromosomePrices, randomCrossoverPoint, (childChromosomeCDetails.chromosomePrices.length-randomCrossoverPoint));
    System.arraycopy(parentChromosomeADetails.chromosomePoints, 0, childChromosomeCDetails.chromosomePoints, 0, randomCrossoverPoint);
    System.arraycopy(parentChromosomeBDetails.chromosomePoints, randomCrossoverPoint, childChromosomeCDetails.chromosomePoints, randomCrossoverPoint, (childChromosomeCDetails.chromosomePoints.length-randomCrossoverPoint));
    System.arraycopy(parentChromosomeADetails.chromosomePlayerIDs, 0, childChromosomeCDetails.chromosomePlayerIDs, 0, randomCrossoverPoint);
    System.arraycopy(parentChromosomeBDetails.chromosomePlayerIDs, randomCrossoverPoint, childChromosomeCDetails.chromosomePlayerIDs, randomCrossoverPoint, (childChromosomeCDetails.chromosomePlayerIDs.length-randomCrossoverPoint));
                        However it gives me this error, relating to the first arraycopy method: Exception in thread "main" java.lang.NullPointerException
         at java.lang.System.arraycopy(Native Method)Please note that in this program, parentChromosomeADetails and parentChromosomeBDetails already hold data when I try to use the arraycopy method, whereas the childChromosomeCDetails and childChromosomeDDetails objects are empty, waiting for the data from the arraycopy methods. Any help would be immensely appreciated.

    it was learning very well yesterday, but that was before I introduced my customised class. I need my class as I need to be able to keep hold of all of the data, rather than just the chromosome points, so that I can see the exact strategy that the algorithm uses.
    It is indeed the child chromosome that is null, and I suppose that it because I had to initialise the int[] chromosomePoints, double[] chromosomePrices and int[] chromosomePlayerIDs as null. What is the best solution to this? using loops to initialise all values in the arrays as 0 before the arraycopy?!
