This makes Flash Builder 4 pretty much useless to me. Anybody happen to know how to fix this issue?
Thanks a lot in advanceUninstalling Flash Builder 4 (my machine is a Mac Pro) and re-installing it solved the issue. Not my favourite way to resolve issues ... but desperate times ask for desperate measures.

BBM error: Uncaught exception:java.lang.Null pointer exception ??
Help. Anybody know what this means and what I need to do to fix it?
It just started a few days ago and BBM will not open up.
I have a Torch 9800 running the 6.0 Bundle 2647; V6.0.0.600, Platform 6.6.0.223You can take a look at the event log to see if you can pinpoint what application is throwing the error and remove it. To get to the event log: Hold down the alt key and press lglg.
Another option is wipe the device, including all 3rd party apps and then try to reload the OS.
If that fails, use JL_Cmder and wipe it that way or resettofactory.
Either way always back up your phone when installing 3rd party apps. -

Any Help will be appreciated. Thank you.sounds like your deployment isn't right - either your classpath isn't set correctly or you haven't included all the classes necessary in your deployment - or if this was working but now it's not then perhaps you removed something?

Sai.k.kHi Konchada,
Is this PI System newly installed?
Let me know!
Moreover have you imported <b>XI BASIS Component?</b>
If it is newly installed, this problem is because you have not imported <b>XI BASIS Componen</b>t. You import the component through Integration Repository Environment.
I think this will solve your issue

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");
String poNumber = (String)vo.getCurrentRow().getAttribute("PoNumber");
OAViewObject linesVO = (OAViewObject)am.findViewObject("CxPoReleaseLinesVO1");
Number lineAmt = (Number)linesVO.getCurrentRow().getAttribute("Amount");
Serializable [] params = {poHeaderId.toString(), poNumber, lineAmt.toString()};
am.invokeMethod("apply", params);
ReleaseAM:-
public void apply(String poheaderId, String poNumber, String lineAmt)
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); }
catch (Exception e) { throw OAException.wrapperException(e); }
totalreleaseqtyVO.initQuery(poHeadNum);
CxTotalReleaseQuantityVVORowImpl row = null;
row = (CxTotalReleaseQuantityVVORowImpl)totalreleaseqtyVO.getCurrentRow();
try { totalqty = (Number)row.getQuantityReleased();}
catch (Exception e) { throw new OAException(e.getMessage()); }
if(totalqty != null)
{ return totalqty; }
else
{ throw new OAException ("exception occurred", OAException.ERROR); }
public Number getBlanketAmt (String poNumber)
Number blanketAmt;
CxBlanketAmtVOImpl blanketVO = (CxBlanketAmtVOImpl) getCxBlanketAmtVO1(); //VO to get total amount on the BlanketPO.
blanketVO.initQuery(poNumber);
Row row = blanketVO.getCurrentRow();
blanketAmt = (Number)row.getAttribute("Quantity"); //gets the blanket amt
if( blanketAmt != null ) {
return blanketAmt ; }
else { throw new OAException ("exception occurred", OAException.ERROR); }
---------The code breaks at the line where I try to get "totalqty" or "blanketAmt" .. It throws a java nullpointer exception.
Thanks for helping me out.

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,

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?! -

PLease Help me !!
I need this urgently.can you explain what your program tries to do... and
at where it went wrong..Sir,
We are trying to make an project where we can make a person register in our data base & after which he/she can search for other user.
The logged in user can modify his/her own data but can view other ppl's data.
We are in a phase of registering the user & that's where we are stuck. The problem is that after the login screen when we hit register (OK- button) the data are not getting entered in the data base.
Can u please help me??
I am using "jdk1.3' - studnet's edition.
I am waiting for your reply.
Thanks in advance & yr interest.
