Help Needed on Null Pointer Exception

Hi All,
Am using the wls10 platform. Any help would be appriciated. Have been struggling on this for a bit now.
Thanks,
The the relevant control code is:
@JdbcControl.SQL(statement = "SELECT p.PATCH_ID, p.REQUIRES,ps.PRODUCT_DISPLAY_NAME, v.VERSION_NAME,p.PATCH_NAME,p.DESCRIPTION, to_char(p.RELEASE_DATE, 'MM/DD/YYYY') RELEASE_DATE, p.SUPERCEDES, p.RELEASE_TYPE, p.KB_ARTICLE, p.SYSTEM_IMPACT , p.DOWNLOAD_LOCATION, p.requirelogin, p.SEVERITY, p.ACTIVE, p.MD5, P.DOWNLOAD_FILE_SIZE from patch p, version v, products ps where p.VERSION_ID = v.VERSION_ID and v.PRODUCT_ID = ps.PRODUCT_ID and upper(p.PATCH_NAME) {sql: whereClause} and v.active = 1 ORDER BY ps.PRODUCT_DISPLAY_NAME, v.VERSION_NAME")
     public Patch[] findPatchByReleaseName(String whereClause)throws SQLException;
The controller code is:
     @Jpf.Action(forwards = {
                    @Jpf.Forward(name = "success", path = "Downloadpage.jsp", actionOutputs = { @Jpf.ActionOutput(name = "findPatchResult", type = com.vmware.s3portal.domain.Patch[].class) }),

Help me,Why Null Pointer Exception!!!!

Hi,
I want to write a javabean to wrap some methods assosiated with database,the source code is like this:
//ConnectToDBMS.java
import java.sql.*;
public class ConnectToDBMS
private Connection conn=null;
private Statement stmt=null;
ResultSet rs=null;
private String driver=null;
public String url=null;
public String user=null;
public String password=null;
public ConnectToDBMS(){}
public void Connect()
try
Class.forName(driver);
catch(Exception e)
System.out.println("can't load driver��"+driver);
e.printStackTrace();
public void setDriver(String Driver)
this.driver=driver;
public void setUrl(String URL)
this.url=URL;
public void setUserPassword(String user,String password)
this.user=user;
this.password=password;
public ResultSet executeQuery(String sql)
rs=null;
try
conn=DriverManager.getConnection(url,user,password);
stmt=conn.createStatement();
rs=stmt.executeQuery(sql);
catch(SQLException ee)
System.out.println("error in query��"+ee.getMessage());
return rs;
public void closeStmt()
try
stmt.close();
catch(SQLException eee)
eee.printStackTrace();
public void closeConn()
try
conn.close();
catch(SQLException eeee)
eeee.printStackTrace();
compile ok,and then called in jsp,the jsp code is like this:
<%@page contentType="text/html;charset=gb2312"%>
<%@page import="java.sql.*"%>
<jsp:useBean id="ConnectToDBMS" scop="page" class="ConnectToDBMS"/>

out.println("<td>"+rst.getString("soft_intro")+"</td></tr>");
ConnectToDBMS.closeStmt();
ConnectToDBMS.closeConn();
%>
</body>
</html>
the database name is mysoft,and has a table named soft,it contains such fields:soft_name,soft_intro,soft_size,url. I found this error when visit this page:

The error is occurring somewhere in your JSP, according to the stack trace. It would help to know which is line 20, but it's hard to figure that out for a JSP. Just another reason why it's a bad idea to put lots of Java code in a JSP. But anyway, do you think it's possible that your putting
scop="page"
in your bean declaration instead of
scope="page"
is the problem? If not, you need to put debugging code in the scriptlet to find where the exception is being thrown.

Help with Null Pointer Exception

Hi, I am working on a simple menu program. It compiles and works correctly except for one item. I am having a problem with Greying out a menu item...... Specifically, When I press the EDIT / OPTIONS / READONLY is supposed to Greyout the Save and SaveAs options. But, when I do that it displays a Null Pointer Exception error message in the command window.
Your advice would be much appreciated!

alan, I've been trying to figure out a solution.
You can initialize it like this
private Action saveAction= new Action();
     private Action saveAsAction=new Action();
THE ABOVE WILL NOT WORK.
because Action is an interface. An interface does not have constructors. However, interface references are used for polymorphic purposes.
Anyway, all you have to do is find some class that implemets Action interface.... I cant seem to find one. Or maybe this is not how its supposed to be done?
Hopefully, someone can shed some light on this issue.
FYI,

Help please I get Null Pointer Exception with my SQL query

The following statement gives me a null pointer exception when executed
from the doPost of my servlet.
rs=stmt.executeQuery(sqlQuery);
The error message reads:
java.lang.NullPointerException
at stockserv.Servlet1.doPost(Servlet1.java:142)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)
===etc.
when I execute the same statement and query (same DB and table) from a standard java
program I do not get the error and get the propper result.
Any obvious thing I should check?
Thanks

Yes line 142 is as follows
rs=stmt.executeQuery(sqlQuery);
I also tried it with the folowing literal statement and get the same error.
rs=stmt.executeQuery("select * from table1 Where symbol= 'brt' ");
Does null pointer mean I am sending a null query or something else?
Again this same statment works from a regular java (non-server)program.
Thanks Again

Help in null pointer exception

I have a null pointer exception and i cant figure out which variable is null,
This is my servlet code.
ArrayList pmArray = pDAO.getPlacemarkByRegion(northEastLong, northEastLat, southWestLat, southWestLat);
            //loop through the placemark
            for ( int i=0; i< pmArray.size();i++) {
                Placemark pm = (Placemark)pmArray.get(i);
                // parse string
                String pmId = pm.getPlacemarkid()+"";
                String pmLat = pm.getLatitude()+"";
                String pmLong = pm.getLongtitude()+"";
                String s = "{\"markers\":[ " +
                        "{\"placemarkid\" : + pmId , \"latitude\" : + pLat , \"longtitude\": + pmLong} + ]}";
                 System.out.println(s);This is my DAO class
public ArrayList getPlacemarkByRegion(double northEastLong, double northEastLat, double southWestLong, double southWestLat)When i get the placemark andNullPointerException appear. I think that my Arraylist is incorrect, I have also try-catch exception in the servlet but it still show me null pointer. Can anyone please kindly guide me?

hmm, i have solved my sql syntext already, but i still manage to get pmArray null.
I have check through my codes but pmArray is still null.

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.

JRC (upg. to CR4E) - Report w Subreport - Oracle DB - Null Pointer Excepti

Hi
We have a Crystal Designer/Developer Version 11.5.10.1263. We develop reports using this.
Most of the reports have SQL Command mode design with JNDI/JDBC connection. It gets deployed with our Web application. And during runtime, when users access these reports from our web application, we typically use Java Reporting Component with Crystal Report Viewer SDK to open and display the report to the user.
Besides other issues, current problem I am having is:
I have a sub-report in my report. I am connecting to Oracle database. If this sub-report does not return any rows, I was getting a Null Pointer Exception. This seems to be a known bug. This happened to us when we had just the above mentioned components.
We recently upgraded just the JAR libraries to the ones packaged in CR4E (Crystal Reports For Eclipse) - initially to get more exporting capability.This upgrade gets us past the Null Pointer Exception issue.
Now, I am getting an error like "Unexpected database connector error". Please see the exception stack trace below if needed. Since we are a product and this display is specific to one out of about 100 different clients; with all the time we spent on making this report stuff work against this oracle DB client, we had finally ended up creating the display in JSP into our general product just for one of about 100 clients. Client must be the Lucky one...As a developer, I felt really frustrated.
One note:- SQL Server DB works perfect.
Other thing - Do we need to change any API calls after upgrading the JARS from standard JRC/Viewer to CR4E package?

I have exactly the same problem. Had posted it on the forum last week, but haven't received any response yet. I just file a single support case ($195) with SAP. If I hear anything useful back, will keep you posted. Please let me know if you are able to resolve the problem.
In my case, I can get my report to work with a single subreport. When I put multiple subreports, I get the same error as you are currently getting.
Check if your report has any special section formatting (conditional suppression etc). Try to remove those to see if it helps at all.

Null pointer exception while executing a scenario from cloned work repo

Hi,
I have involved in ODI 10g to 11g migration activity.
For doing that activity, i cloned the existing master and work repositories into some intermediate master and work schemas.
Created new configuration settings for pointing the odi 10g to the intermediate master and work repositories.
Everything is fine till this, but while executing any interface or package anything from intermediate work repo designer, am facing error as below
"Cannot start the execution, Null pointer exception"

Note: My previous and cloned Master's work's repository id are same
Could anyone pls help on this.
Thanks in advance..

The error is resolved by following the below solution
If you receive an error in ODI 10g like;
java.lang.Exception: Error during Session launching
at com.sunopsis.dwg.dbobj.SnpSession.remoteExecute
or
java.lang.NullPointerException
at com.sunopsis.dwg.cmd.DwgCommandBase.prepare(DwgCommandBase.java)
1.First check whether your agents are working and test connection to repositories. If everything ok, you might have changed your repository name recently.
2.When you export your work and master repository and import to another schema or database and whether you connect to your imported repository, you change your repository name in your first environment.
3.Correct order is first rename your Master Repository name, log off / log on and change your Work Repository name and check below fields in both your Master and Work Repositories in both environments.
Master Repository : SNP_REM_REP
Work Repository : SNP_LOC_REPW
REP_NAME column of MASTER_REP.SNP_REM_REP should be equal to REP_NAME column in WORK_REP.SNP_LOC_REPW.
You cannot see WORK_REP.SNP_LOC_REPW value in ODI Topology Manager and if you are changing your repository name you need to update value from database.
Change the value from DB, loggoff and logon the user and connect the designer again.

What is actually throwing the NullPointerException? rs.getMetaData() or table.setModel()?

You would need to get BEA support, after verifying you are on a supported configuration (http://edocs.bea.com/jrockit/jrdocs/suppPlat/supp_142.html).
Otherwise you may need to try update 10, or use Sun JVM.

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?!

Null Pointer Exception While calling function

Excuse my ignorance, as I just started programming in Java, but while trying to give control to a function other than main(), I get a null pointer exception. I don't think that I'm calling the function properly, because I feel that I may need to start a new thread, but I don't know how to go about it. Please help.
Here's the code(not the whole thing, just the important part):
public static void main(){
//some stuff to run
mainplace();
public static void mainplace(){
//stuff is in here
}

firstly the first main . Is this a typo
shouldn't it be
public static void main(String [] args) {
mainplace();
I say this cuz when u complile a class and try running it the first thing that gets called is the main method with String[] as the arguments.
public static void mainplace() {
// some thing here
}it would be better if u post the code cuz, frankly nothing can be understood from ur previous post.
there could be many reasons for the NullPointerException.

Returning vector and null pointer exception

Hi, I'm writing a mailing program which so far is working fine, but I have now run into a problem which is completely throwing me. My mailer needs to be able to load multiple attachments - and also to be able to deal with an HTML text which contains multiple images. In each case, what I'm trying to do is to put the attachments and the images into separate vectors and process them through an iterator. The logic, at least, I hope is correct.
I can get my code to compile but it keeps throwing a null pointer exception a runtime. Somehow, I just can't get it to pass the vector from one part of the code to another.
Can anyone help me? I've tried various things, none of which seem to work. My code, as it stands, is posted in a skeletal form below.
Thanks for any ideas:
public class MailSender
   // declare various variables, including:
     Vector embeddedImages;
     String HTMLString;
    public MailSender()
        setup();
    private void setup()
     //this part of the program sets up the various parts of the mail (to, from, body etc)
      HTMLString = "blah blah blah"; //sample HTMLString
       Vector embeddedImages = null; //is this correct?
        if (HTMLString.length() > 0)
            processHTMLString(HTMLString);
     private String procesHTMLString(String htmlText)
        Vector embeddedImages = new Vector(); // I construct my vector here, is this correct?
        //Here I process the HTML string to extract the images
        //get the file path of the image and pass it to the vector
        addToVector(imageFile);
        return HTMLString;
    public Vector addToVector(String imageFile)
        embeddedImages.add(imageFile);
        return embeddedImages;
    private void send()
        //this part does the sending of the mail
        //at some part in this method I need to get at the contents of the vector:
        //but this part isn't working, I keep getting a null pointer exception
        Iterator singleImage = embeddedImages.iterator();
        while (singleImage.hasNext())
    public static void main(String[] args)
        MailSender ms = new MailSender();
        ms.send();
        System.out.println("MailSender is done ");
}

>>>>while they don't have a clue on how the language and/or programming in general works.
Thank you, salpeter, for your esteemed estimation of my programming competence.
>>>What I'm wondering is: how come people always start building applications... blah blah
The reason being, is that it happens to be my job.
OK, I'm perhaps slower than most and there are things I don't yet understand but I get paid probably about a tenth of what you do (and maybe even less). I regard it as a kind of apprenticeship which, after a past life having spent twenty years packing crates in a warehouse, is worth the sacrifice. Six months ago I'd never written a line of code in my life and everything I've learned since has been from books, the good people in these forums, and a lot of patient trial and error. It's hard work, but I'll get there.
I say this, only as encouragement to anyone else who is trying to learn java and hasn't had the benefit of IT training at school and a four year computing course at university paid for by the parents, and for whom the prohibitive cost (in both time and money) of most java courses would never allow them to get on this ladder.
Excuse my somewhat acerbic posting, but comments such as yours tend to provoke...
Thank you EverNewJoy for explaining this to me. I haven't had time yet to try it out, but at least the concept now is clear to me.

Remove finally block in servlet init() as the call to destroy() in the catch block will clear ThreadLocals
if there is an error. Move it to the end of try block instead since the init() thread doesn't need any
thread locals set.
Log the startup error before calling destroy() in init() catch clause.

Hello!
I had a similar problem under WebLogic 6.1 SP4 after deploying a war-file with
a bug.
After deploying the corrected file, it seemed that the old version was deployed
again.
Perhaps this behaviour will help you to load the new application/ejb:
- undeploy
- remove from targets
- move to targets
- deploy

hi all,
i have found a werid problem in deploying applications in Solaris 8
for weblogic
7.0.
i have deployed one EJB, and the first time i access it (thru teh web
app embedded
in the .ear) it gave me a null pointer exception because i was failing
to lookup
one environment variable.
so, i fix the code, rebuild the ear and redeployed, and the same error
happened
again.
i am sure i did not do any mistakees because i have put some system.err
statements
in the bean code to show the workflow, and when i have deployed it on
Window 2k
the statemens appeared.
but in solaris they didnot appear, and i got the same exception that
i had before..
it looks like wls is caching teh ejb, because whenever i redeploy it
(adding more
and more system.err statements) it always execute the faulty code of
when deployed
the very first time.
anyone can help?
regards
marco
