SQLException and NullPointerException

hi,
experts,
i have one problem,in exception handling
i am throughing SQLException from one method of class which is returning int data but it will give the NullPointerException, when i am calling this method in another class.
please give some hints.,

You may not initialized that object. NullPointerException will come only if the Object is null and calling any function on that.

When I try to access data in the cd list I get an nullpointereception error, like assiging int e = L.firstNode.data.iSjanger; Or when I try to save the list, I get a nullpointerexception, I seem to be able to create cd in the list but when I try to access the data its not there.

It is an assignment I cant use the premade LinkedList package.
While that did solve it, I can now add CDs to my archive but as I have found out when i try using other methods(like write to disk lagreCdArkiv() ) I get and nullpointerexception. I tried letting it rest and try another part of my assignment which included another linekd list. Same problem I can create a Hobby in a Hobbylist but when I try to compare and work with the data I get nullpointerexception.
I must be doing something consistently wrong.
Let me supply some more classes for comparison.

Date return values and nullpointerexception

Couple of problems I was hoping to find some help about:
First, I'm passing a String, Number and Date into a private static void method. The String and Number values are updated and returned / retrieved fine, but the Date isn't and holds it's original value. How do I get a Date value, updated within the method, to be returned?
Second, I get a NullPointerException from the following little slice of code. The Olistitem is a class created by JPub FYO.
Olistitem[] listItem = new OSyncEnumlistitem[2];
listItem[0].setNumbervalue( new BigDecimal(1) ); // It's expecting a BigDecimal.
Any ideas?
Thankyou for any help.

For the first one, probably need some source code to
answer.
Are you returning a new Date, or just the original
object?I'm trying to assign a new date value to the date object passed in and then retrieve the results into an array. Some source code:
//To call the method.
Object argsV[] = new Object[argsValue.size()];
argsValue.toArray(argsV);
method.invoke(null, argsV);
// The method itself.
public static void test(CramerVarchar first, CramerNumber second, java.util.Date third, SyncEnumList fourth) throws ParseException
try{
first.setValue("Test String Returned");
second.setValue(new BigDecimal(second.getValue().intValue() + new BigDecimal(1).intValue()));
String dateFormat = "dd-MM-yy HH:mm:ss";
String theDateString = new String ("15-07-03 10:24:05");
SimpleDateFormat date = new SimpleDateFormat(dateFormat);
third = date.parse(theDateString);
catch (SQLException e)
System.out.println("Error in tester");
Any clearer as to what I'm getting at?!

Fatal Error and NullPointerException in Oracle XML Transformer

Hi,
I'm building a dom tree in memory with oracle xml parser. Then I transform the dom document into a string to send xml to the client. But I get an fatal error on calling transform.
I don't know what could be the problem, because apache and weblogic parser works, an when I create a dom document with org.w3c.dom elements and statements then the xml document can't be invalid,
because the document implementation would throw an exception if wrong nodes or something like this should be inserted...
I'm using oracle xml parser 9.2.0.4 for java, bea weblogic 7.0 and win2k.
Thanks for help.

The second thing is that the Oracle XML transformer is
NOT threadsafe. I was using several threads using different templates to transform an incoming XML simultaneously but was ALWAYS getting internal XSL errors
and Nullpointer Exceptions. I solved this by synchronizing the transformation, but I don't like it.

Done. I should have read through the usage of Icons in Java Tutorial first. If anybody has this similar problem, that is a good source for clearing.

ParticipaneFeed and NullPointerException

Hi,
I am trying to test LDAP integration in StandAlone Enterpricese server. I have added the following line to webconsole.properties:
fuego.webconsole.userFeed.enabled=true
When I go to the BPM Proess Administrator and Organizational Settings/Enable Participant Feed, I get the NullPointerException.
When I return to Organizational settings after this, I See the Participant Feed Settings, but can not "Save" them, because I get another null pointer exceptions.
I am attaching the stack trace bellow.
Any ideas what is going wrong?

I am getting the same error, when I migrated the web application from Tomcat to Weblogic. It looks like it is JSF related.

Realm and NullPointerException

I am attempting to create a custom realm following the JDBC Realm as an example.
I have done the following:
-update the login.config file to include my new realm
-added the realm under the security tab
-set the new realm as default
-compiled my realm classes into a jar file and added that to my classpath
When I attempt to start the server, I still get the following error:

never mind - figured it out.
To my custom realm, I needed to add the
'jaas-context' property.

Upgrade to v7.1, numerous issues and NullPointerException

We did an upgrade of our IDM system with environment- Solaris9, Tomcat 5.0.x, Oracle 10g
And we used -nodisplay option.
The process repeatedly crashed on the 2nd half of the PostProcess, and we were stuck importing update.xml either through browsers (after starting server) or using lh console.
The exception in the log is invariably GUI related, typically referencing the following:
UpgradeProcessProgressPanel
WizardTreeManager
cliConsoleInteraction
The user form is a customized tabbed user form, and has been renamed and referenced in "Form and Process Mappings".
1)
From the debug page, we can List Objects, and then go to an individual object of that type, and View or Export, but when we use Export Objects, on the main debug page, we only get the following line.
<p class="errortxt">Permision denied. Click the Back button on the browser to continue</p>
2)
We are getting a NullPointerException (NPE) when we try to create a user and save.

Struts: Odd problem with ActionErrors and NullPointerException

Hello,
I'm fairly new to Struts, and I'm trying to set up a relatively simple application. I've been running into this problem when trying to validate an ActionForm through the validate() method.
The validate method call is very simple:
public ActionErrors validate(
          ActionMapping mapping,
          HttpServletRequest request) {
          ActionErrors errors = super.validate(mapping, request);
          if (!firstName.equals("foo")) {
               errors.add("firstName", new ActionError("error.firstName"));
          return errors;
     }My problem is that whenever the if-statement evaluates to true, a NullPointerException is thrown when the errors.add() call is excecuted. It seems to me that the problem must somehow be related to the ActionErrors object being null and the add() call failing. However, I have a hard time seeing how this could be the case. Other examples I have looked at seem set up the validate method in the exact same way.
Now, I have verified and tested the following:
* the if-statement evaluates properly, meaning that the firstName field is not null
* the message resource bundle is available, so it couldn't be that it's related to the property not being found in the bundle
This might be something simple, but I am a bit stumped here, so any help would be greatly appreciated.
Thanks,
Morten

Well, never mind. I just replaced the call to the super constructor with a plain ActionErrors constructor, and then everything worked. Hmmm... so much for blindly copying code you're not entirely sure you understand :)

EMConsole : ADF_FACES-60098 and NullPointerException

Hello All,
I have setup a SOA Cluster in a distributed environment. The topology of cluster (AS with 2 MS in a domain) is like AdminSever -> Machine 1 , MS1-> Machine 2, MS2->Machine 3. They are using unicast methodology and cluster is running fine. Now I am trying to customizing it.
I am trying to configure the callback URL and SOAPURI through emconsole. For that, I am clicking [farm_MyDomain->SOA->soa-infra[MS] and right click -> SOA Administration->Common Properties]
For one Managed Server (MS1) it works fine but for another MS (MS2 running on different machine), I am getting a pop up window saying
java.lang.NullPointerException
ADF_FACES-60097:For more information, please see the server's error log for an entry beginning with: ADF_FACES-60096:Server Exception during PPR, #4
AdminServer Logs gets the following exception: Any idea where I am going wrong? is it somewhere missing configuration lying in cluster?+

Many thanks in advance.

Frank,
I do not get this error when I run the application on the Weblogic standalone server. I do not get this error when I run the application on my integrated weblogic server, unless I run it is debug mode. I do get it on my integrated weblogic server if I run in debug mode.
Can you please give me an idea of where I can look for settings on the other weblogic servers where this is happening to see if I can chase this down? I am not a weblogic server admin by any means, but I have looked at the Debug tab for the server to see if I can see anything enabled. Unfortunately, I may not be looking in the right place to know if there is some kind of debug setting enabled.
Any assistance would be greatly appreciated! This is happening to our users on our production server as well.
Thank you!

G.drawLine and NullPointerException

ok so heres my method
     private void putLine(int x, int y, int x2, int y2){
          Graphics g = getGraphics();
          g.drawLine(x, y, x2, y2);
          g.dispose();
     }and at the g.drawLine it gives me a NullPointerException. I've debugged and all my variables are there and initialised. But as soon as my program gets to the drawLine part it goes haywire, any ideas?

For those who haven't figured it out, there is no Graphics available to a Component until the Component is on screen. That means added to a Container that is onscreen (such as an AWT Frame or a swing content pane) or added to a Container that in turn is on screen, such as a JPanel added to a content pane.
As another note, I'm not sure your call to dispose() is helpful. "g" goes out of scope (and therefore subject to gc) at the closing curly brace on the next line.

GaugeMonitor and NullPointerException

Hello all,
I'm opening a remote jmx connection to a weblogic 8.1 server and create a gaugemonitor for the heap size. So far so good and everything works fine. But when I stop my application, the weblogic server throws the following exception:
####<10.04.2006 17.02 Uhr CEST> <Error> <Kernel> <svstp> <testApp1> <ExecuteThread: '2' for queue: 'weblogic.kernel.System'> <<WLS Kernel>> <> <BEA-000802> <ExecuteRequest failed
java.lang.NullPointerException.

at weblogic.kernel.ExecuteThread.execute(ExecuteThread.java:224)
at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:183)
at java.lang.Thread.startThreadFromVM(Unknown Source)

I remove the notification listener and unregister the GaugeMonitor, but nothing changes that behaviour.
Quite interesting is the following event: I put a 5 second sleep pause between closing the context and exiting the application. The above stack trace appears only when the app exits.
Thanks in advance for any help.
Sebastian.

Thanks for the reply, much appreciated..
It works now. I spent all day trying to figure it out.

Unicode and SQLException

Hi
I have a problem with SQLException and a unicode environment ( env was created with Environment::createEnvironment("OCCIUTF16","OCCIUTF16") ):
what() from std::exception and getMessage() only give a "0" as message.
getUStringMessage() contains the message.
=> you can't catch the exception as std::exception since you can't get the message.
Is this observation right? Is there a solution to this problem?
Lars

Thanks for the reply. I believe we already have this jar file in classpath but are confirming... in the mean time this seems to have worked:
In the Data Acces Object:
//Define a UTF-8 char set:
CharacterSet myCharSet = CharacterSet.make(CharacterSet.UTF8_CHARSET);
//Define Arrays as follows:
oracle.sql.CHAR[] accountNameArray = new oracle.sql.CHAR[shipperCount];
//Populate them with Strings containing unicode values
accountNameArray[ i ] = new oracle.sql.CHAR(shipperAddressDTO.getAccountName(), myCharSet);
//Set FormOfUse to FORM_NCHAR as follows:
l_cstmt.setFormOfUse(5, oracle.jdbc.OraclePreparedStatement.FORM_NCHAR);
//Use OracleCallableStatement & set array params as follows:
l_cstmt.setPlsqlIndexTable(5,inputDTO.getAccountNameArray(),inputDTO.getAccountNameArray().length,inputDTO.getAccountNameArray().length,
OracleTypes.CHAR,50);

}above is the code..
I'm a real newB and it'll probably look like a sloppy, buggy code, but still:
On some of the tables in my DB (tables BaBe,C,O,M,R) i keep gettin a NullPointerException. Other tables work fine.
I read about this kind of exception but I can't figure out where the problem is! the tables r all filled with data, so the String field "lemma" ain't null..
Any clue?

btw I'm learning Java with this book and most of the
examples extend swing classes, so I thought it was
ok..
I started coding 4 days ago and your advice is really
useful at this point.
I'll try and use swing classes as they are unless I
really mean to add functionalities.
The matter is that I really HAVE to find a way of
queryin a huge database (this ain't a school project)
in few seconds and I wanted to check Java speed on
doin it.
Plus I WANNA LEARN! :-)You don't have to be perfect right away, but think about what I said and try to figure out why it's beneficial as you learn. At first it porbably won't make sense but then one day it will click.
For now, pull out the capito method and create a new class. What you will be doing is creating a DAO (dabase access object) that you will use from other parts of the code. This means that if next week, you need to make a web version of this program, you won't need to rewrite that part of the code.

Somebody can help me with this ?
java.sql.SQLException: Connection to remote site no longer valid
Sometimes this error message appears in the moment when the next code execute, the database is Informix 10

note. The stored procedure connecting with two databases (informix 10 & informix 9)

Where do you close the connection and statement/result set?
