NullPointer Exception in WLS SP2

Hi,
I get a null pointer exception while deploying an application (.ear) in WLS
7.0 SP2. The same app
deployed fine in WLS 7.0 SP1.
It seems to fails in
weblogic.management.runtime.DeployerRuntimeMBean.activate(realPath,
name, null, info, null);
Has the behavior of this method changed in SP2?
Thanks for any input.

NullPointer exception in request.getParameter().indexof(.....) only in 6.1

Hi
I have one full working application (containing WAR + JAR) files.
Right now this application is working absolutely fine in weblogic 6.0 sp1 on
WINNT & Solaris.
In this application, we accept events to save data from external
applications like excel files.
Now code in JSP is -->
Line 1: String Data = request.getParameter("data");
Line 2: Data.indexof(........);
Now in case of weblogic 6.1, i am getting NullPointer Exception in line 2,
but I am NOT getting any exception in case of weblogic 6.0sp1.
To my surprise, I am also printing request obj parameters values, whenever
jsp get called from external source, there it is printing value of "data".
I am totally clueless!!
Any idea plz?
Ashish Jain

Looking very closely at request object contents..
Wht i am sending (posting) from excel file-->
xmlData=<?xml version="1.0" encoding="UTF-8"?><reportSheet bu="SHKXXX"
report="PBrandContr" sheet=
"PBrandContr" year="2002" coType="A" status="0" brId="PIC" act_brId="PIC"
opt="P" ></reportSheet>
But 6.1 interprets like this ---->
key is --------> xmlData=<?xml version="1.0" encoding="UTF-8"?><reportSheet
bu="SHKXXX" report="PBrandContr" sheet=
"PBrandContr" year="2002" coType="A" status="0" brId="PIC" act_brId
And Value is -------> "PIC" opt="P" ></reportSheet>
This thing is causing all problems.
I am not observing this kinda behaviour in 6.0sp1.
Thanks

Nullpointer exception... any help would be appreciated

In advance, I apologize for any ignorance which I may obviously have... I'm in the process of learning Java, and am used to C/C++... In any case, I'm running into a nullpointer exception while 'compiling', which I'm having trouble figuring out... I'll list everything below, but this message will be rather long, as I will try to include everything I can. For this reason, I will ask my questions here, at the top:
1) A null pointer exception, I believe, is generated when something is being referenced which is currently null, for example "a=null; a.b;" yields a null pointer exception. However, is there any other way that one is generated?
2) Are there methods to figure out what/why something is null other than simply looking at it? As shown below, it seems that just looking at it runs you in a circle from line to line, file to file, which leads you back to the beginning where nothing is actually null... (I'm probably just not seeing it, but that seems to be what's happening to me)
So now, on to the actual code:
The following is a printout of the debugging info:
~/bin/jdk*/bin/java -classpath classes jamie.Main
java.lang.NullPointerException
at jamie.Main.Sys_Log(Main.java:110)
at jamie.Main.Setup(Main.java:142)

20    )   private static Log                sys_log;
108 )   static void Sys_Log(String msg)
109 )   {
110*)        sys_log.Log(msg);
111 )   }
142*)   Sys_Log("Server warming up...");
182*)   Sys_Log("Server shutting down...");
50 )     public static void main(String[] args)
51 )     {
52 )          try
53 )          {
54*)                Setup();
85 )     catch(Exception e)
86 )     {
87 )          e.printStackTrace(System.out);
88 )          err_log.Log(e.toString());
89 )     }
90 )     finally
91 )     {
92*)            Shutdown();
93 )      }Now, various things that I have tried, and their result (you can probably skip this section, as these were mostly futile efforts):
What seems odd to me is that the initial error is on line 110, which is the logging function Sys_Log. Since it's a null pointer exception, I would assume that sys_log is null? and thus in calling Log we're generating that error... I'm not entirely sure that that makes sense, though. Additionally, and what I find odd, is that if I change it to what I will list below, I get a slew of other seemingly unrelated problems:
20    )   private static Log                sys_log;
108 )   static void Sys_Log(String msg)
109 )   {
110#)        if (sys_log!=null)
111 )        sys_log.Log(msg);
112 )   }This results in a problem with function Err_Log, which I change the same way, resulting in the following:
java.lang.NullPointerException
        at jamie.Area_LUL.Load(Area_LUL.java:23)
        at jamie.Main.Setup(Main.java:161)
        at jamie.Main.main(Main.java:55)
Exception in thread "main" java.lang.NullPointerException
        at jamie.Main.Shutdown(Main.java:186)
        at jamie.Main.main(Main.java:93)In Main.java the following lines are generating the error:
160 )   lul = new Area_LUL();
161*)   lul.Load();And in Area_LUL.java I also have the following:
14 )class Area_LUL implements LoaderUnloader
15 ){
16 )    public void Load()
17 )    {
18 )        try
19 )        {
20 )            areadir = new File("./areas/");
21 )            SAXParser p = SAXParserFactory.newInstance().newSAXParser();
22 )
23*)            for(File curr : areadir.listFiles(new Area_Filter()))
24 )            {
25 )                p.parse(curr, new XMLParser());
26 )            }
27 )        }Where in the above, the for statement is generating the null pointer exception... which would tell me that areadir is null, however it is defined as new File("./areas/"); Also, lul (defined as new Area_LUL(); is generating the same error, though it is clearly defined in Area_LUL.java at the top of the last excerpt.
Also, LoaderUnloader is defined in another file as follows:
interface LoaderUnloader
    void Load();
    void Unload();
}which are defined in Area_LUL in Area_LUL.java .
A major theory which I currently have is that the compiler is beginning with my main.java file, and not seeing the class definition in another file, and thus attributing the class obj I create as null, which is causing the error, but I also am not sure if this is possible...
My imports for Main.java are as follows:
package jamie;
import java.io.*;
import java.util.*;I'm not entirely sure what the package is including, however I do have a jamie.jar file in another directory (../../dist) (could be referencing that?). Also, to compile the source I am using the following command:
~/bin/jdk*/bin/java -classpath classes jamie.MainHowever my classpath (I believe) isn't set to include all my files in the given directory. I wouldn't believe that this would be an issue, however if it could possibly be causing this, I can figure out how to set it properly. Also, this should mean I'm starting with Main.java, and perhaps I am right in concluding that it isn't referencing Area_LUL in another file properly, which is setting it as null?
In any case... Any help would be greatly appreciated. This has been a bit of a struggle for about a month now, trying various resources, moving things around, etc... Thanks so much for your time in reading,
-Jess

I'm not able to follow the program flow from your post. Please create a small standalone program that exhibits the problem and post that back here.
Your assumption re a NPE is correct, that's the only way they're generated.
There are no "canned" methods to resolve NPEs. The best solution is to put System.out.println statements for all of the involved objects and variables immediately preceeding the error line (in this case, 110) and something will show null. Usually that's enough info to backtrace to the real cause.

Java.lang.NullPointer Exception in File-RFC-File wtihout BPM scenario

Hi All,
I have implemented scenario File - RFC - File without BPM in PI7.1 according to below link by bhavesh
[File - RFC - File without a BPM - Possible from SP 19.;
but I am getting error java.lang.NullPointer Exception in Audit log of sender communication channel when it enters in ResponseOnewayBean.
I had implemented the same in PI 7.0 but there it was working fine.
Is there any limitations on the use of the above beans in PI7.1 as I could see two more threads on the same unanswered yet.
Please help me in resolving as it is priority task for me
Thanks,
Amit

Sometime back I saved this SAP Note 1261159 for this error. Not sure if it is still valid. Try to get it implemented.

Help with nullPointer exception

Hi,
I would like some help identifying and error in the code below. Im getting a nullPointer exception at the location specified in the code. Im adding elements to a tableModel. What puzzles me is that the strings I add to the model does contain values. And it does not complain about adding them. Perhaps this is just a simple error, and you more experinced programmars are probably loughing at me ;)
void getTests() {
      String[] idNummer = getDirectory(); //gets filenames from a directory
      for (int i = 0; i < idNummer.length; i++) {
         idNummer[i] = idNummer.substring(idNummer[i].lastIndexOf(dataSeparetor) + 1, idNummer[i].length());
// just sorts out specific parts of the filenames
for (int i = 0; i < idNummer.length; i ++) {
System.out.println(idNummer[i]); //I print the sorted filenames and they not null
testModel.addElement(idNummer[i]); //I add them to the table model
testNr.setModel(testModel); //and gets a nullPoint exception here??

I'm sorry, you mean testNr. Don't pay any attention to the above post. it is also declared directly in the class:
public class GUI extends JFrame implements EventListener {
JList testModel;
}and creates an instance here:
public GUI {
testModel = new DefaultListModel();
getTests();
testNr = new JList(testModel);
      testNr.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
      testNr.setLayoutOrientation(JList.VERTICAL);
      testNr.setPreferredSize(new Dimension(80, 80));
      testNr.addListSelectionListener(new ListSelectionListener() {
         public void valueChanged(ListSelectionEvent event) {
      leftPanel.add(testNr, BorderLayout.EAST);
}

ArrayList nullpointer exception

I'm creating a game called bubblebreaker in Java, with the principle off model, view and controller classes.
In my model class I create a list of bubble objects. In the view I make these bubbles visible and in the controller class I react on external events (mouseclicks, ...)
My design is almost finished but I'm having some troubles removing my selected bubbles.
When I have selected my bubbles I want to remove them with another click on that bubble.
In the method deleteBub(Bubble delete) I will use the "set" method from the arraylist and make the bubble object "null":
protected void deleteBub(Bubble delete) {
        bubbleList.set(delete.getNumber(), null);
}This is the error:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
+     at Model.deleteBub(Model.java:69)+
It also points to this method:
In the view class I check if the object is null:
protected void drawBub(Bubble bubb, Graphics g) {
            if(bubb!=null) {
                g.setColor(bubb.getColor());
                g.fillOval(20*bubb.getX(), 20*bubb.getY(), 20*model.getRadius(), 20*model.getRadius());
            else System.out.println(bubb.getNumber() + " is null");
}There are no compilation errors. I just get a nullpointer exception when I click the second time on a bubble, so when it should be made null.
Edited by: Lektroluv on May 5, 2009 2:22 AM

I think I'm not on the same level as you.
The set command replaces the original bubble object with null, wright?
So for example the list changes from this:
new Bubble(.....)
new Bubble(.....)
new Bubble(.....)
new Bubble(.....)
...to this:
new Bubble(.....)
null
new Bubble(.....)
null
new Bubble(.....)
new Bubble(.....)
...The second list isn't good, because it has "nulls" in it?!?!? --> nullpointer exception?
What I've done next is in stead off replacing it with null, replacing it with new Bubble(BLACK ...)
new Bubble(.....)
new Bubble(BLACK ...)
new Bubble(.....)
new Bubble(BLACK ...)
new Bubble(.....)
new Bubble(.....)

1 View linked to 2 CompCont: NullPointer Exception

Hi,
Here is the architecture of my app :
MainView --> CompContA --> ModelA (RFC function A)
........|
........|---> IntCompB --> CompContB --> Model B (RFC function B)
And here is the content of the MainView :
AdviceNumber : [
Z2_I_Rechercher_Avis_Input.AdviceNumber) | RefreshButton1
UserId : [Z2_I_Rechercher_Bottin_Input.UserId) | RefreshButton2
Name : [Z2_I_Rechercher_Avis_Input.Output.It_Infos_Bottin.Name)
Now, my application works when I populate an AdviceNumber and press the RefreshButton1. At the return, the name field is refreshed and I use some Java code to move the UserId that my function returned to the UserId of the screen. This works well.
Then if I change the value of the UserId in the screen and press the RefreshButton2, the second function returns me another name, and I use some Java code to move this name into the Name field of the screen. This works well too.
The problem is that I can't use the refreshButton2 first! I get a NullPointer exception.
And I know why, it's because the « Output » structure of my Z2_I_Rechercher_Avis_Input is not initialized (since the refreshButton1 has not been used yet).
But I can't find the right way to code it.
Can you help me, thanks!

I want the user to click on the button he wants.
I just need to know how to initialize the Output.Struc1 when the user decides to click on the RefreshButton2 First.
It's the line in bold that give me the error (but that line works well when the RefreshButton1 is used first!)

     wdThis.wdGetAvisCompController().executeZ2_I_Rechercher_Avis_Input();
     //$$end
     // At the return, we need to refresh the values of the screen with the ones returned by the function.
     // Access to the structure showed on the screen
IIt_Infos_BottinElement AvisInfosBottinEl = wdContext

JUTreeNodeBinding question (nullpointer exception in getAttribute)

Hi,
I've got a question about a piece of code. I've used a JTree which displays a recursive tree, which is working fine. I want to do something when a node is selected. I have the following piece of code:
jTree1.addTreeSelectionListener(

     public void valueChanged(TreeSelectionEvent e)
       DefaultMutableTreeNode node = (DefaultMutableTreeNode)jTree1.getLastSelectedPathComponent();
       if (node != null)
         JUTreeNodeBinding tnb = (JUTreeNodeBinding)(node.getUserObject());
         if (tnb!=null)
   });this code is taken from some example I've read on this forum and slightly modified (I can't find the original posting).
Now, according to the sourcecompletion feature, tnb has methods like getAttribute, getAttributeDef. But when I call one of these methods on tnb (where the '...' is in the example above), I always get a nullpointer exception , somewhere inside the getAttribute call. (the variable 'tnb' itself is not null)
Why wouldn't this work? Shouldn't the getAttribute calls give me access to the attributes of the row from the view that corresponds the selected element?
The logwindow shows this for the nullpointer exception:

Bit of a coincidence.. I was just running into the same problem. But if you check getAttributeDefs(), you'll see that there only is one attribute available, namely the one that is being displayed in the tree. (the 'description'-attribute)
Or at least, that's the case with my sitation.
I would love to be able to address all available attributes, eg. foreign key fields, but that doesn't seem possible.
At the moment, I'm using the following work-around, which of course is far from ideal:
Key key = tnb.getRowKey();
ViewObject vo = panelBinding.getApplicationModule().findViewObject("SomeVO");
Row[] rows = vo.findByKey(key);
if (rows == null || rows.length != 1)
System.out.println("Notice: not 1 rows");
return;
Row row = rows[0];
// now you can fetch all the attributes

Getting nullpointer exception in Tomcap using getRealPath()

Hi,
I have the following code snippet, but getting nullpoint exception when I try to read a file in jsp.
String realPath = this.getServletConfig().getServletContext().getRealPath("//AUDIT_TRAIL.xml");
File fileDef = new File(realPath);
Can someone tell me what I am doing wrong, or how i can read a file in jsp that works in tomcat 5

why the double slash? / is not a special character ( b]backslash is, and so you would need \\)
The file is sitting in the root of your web app?
String realPath = this.getServletConfig().getServletContext().getRealPath("/AUDIT_TRAIL.xml");
// and if it doesn't work, try this to see what it IS looking up
String realPath1 = this.getServletConfig().getServletContext().getRealPath("/");
System.out.println(realPath1);If you ware loading a file, you might consider using the getResourceAsStream() method.
Cheers,

Look up the createImage(int width, int height) method in the Component api abd follow the link to its description in the Method Detail section. Note that this method will return null if the component is not displayable. Try placing your inspection code after the call to setVisible.

Java.lang.NullPointer exception and operating systems

Do different operating systems handle the NullPointer exception differently? I have an application that has a screen come up when you click a button. However, the app attempts to process some data before bring up the screen. Sometimes the data is null. The application works fine on linux red hat. However, the screen does not come up on HP Unix. I am not looking to fix the code (even though it may need fixed), but I am looking for an explanation why app works differently in this regard.

Do different operating systems handle the NullPointer
exception differently? Nope.
My guess is that the different OSes have different threading models. In one case X amount of work gets done in the non-GUI thread before the GUI thread tries to do its thing. In the other OS, X+1 amount of work gets done, leading to different states for the GUIs to act on. This is almost certainly a bug in your app.

Java.Lang.NullPoint.Exception in OWB Mapping

Hello Everybody
We are building Data Warehouse using OWB Repository 9.2.0.2.0. When we are validating or deploying the created map we are getting Java.Lang.NullPoint.Exception. This leads to blank screen. We are unable to recover the map. Sometimes, synchronization works to recover the map, but not all the times.
Is there any solution to it?

Is it possible to solve the problem without migrating? I have the details of error as follows --

Whatz java.lang. NullPointer Exception.(Unknown Source)??

Hi All,
In my application, i am getting java.lang. NullPointer Exception.
Is it thatthe application not finding the above Action Class at Runtime??
Any help would be highly appreciated..
Thanks in Advance..
Shridhar..

Read the fucking API.
Thrown when an application attempts to use null in a case where an object is required. These include:
- Calling the instance method of a null object.
- Accessing or modifying the field of a null object.
- Taking the length of null as if it were an array.
- Accessing or modifying the slots of null as if it were an array.
- Throwing null as if it were a Throwable value.
Applications should throw instances of this class to indicate other illegal uses of the null object.
