NullPointerException with bc4juix:InputRender / JDeveloper9.0.3

I've got a situation dependant exception. It's content is quoted below. As I've found out, the tag <bc4juix:InputRender> causes it. If, for example a <uix:textInput> is used instead everything would go right. The error came only with JDev 9.0.3, there were no error with JDev 9.0.2
I've got a multipage uix/jsp browse-edit application. The main difference from the similar application, generated by a wizard is that the edit form contains several tabs. Every page contains the same ApplicationModule in a Statefull releasemode.
The exception comes up when and only when within a single transaction I have edited a row and without a commit/rollback would try to edit another row.
The releasemode is definitely important either. If Stateless is used in a browse page, the exception disappears (in some cases).
Now I have to say that I don't know what would happen if different release modes would be used in different pages.
Thank you.

Can you set a breakpoint at the
oracle.jbo.html.jsp.blaf.RowSetDataObjectList.selectValue
method and let me know which object is null. I would gues you are ending up with a null oracle.jbo.Row.

Hi,
I am getting java.lang.NullPointerException with OracleXMLParser V2.
Following is some of the code snippet. I am not sure where I am going

..... after this I insert the record into database.
Your help is greatly appreciated.

Java.lang.NullPointerException with FTP receiver

Hi All,
I have a java.lang.NullPointerException in the Runtime Workbench for my FTP Adapter, that is a receiver.
At SXMB_MONI all the messages are successful.
What this could be?
Thanks in advance,
Daniela

Naveen,
Thanks for your help.
I took a look in RWB and it seems like there was an error when CC tried to connect with the FTP server. The last two messages are:
Success -> Connect to FTP server "10.112.144.108", directory "\interfaces2\conversionesTest"
Error -> Attempt to process file failed with Error occurred while connecting to the FTP server "10.112.144.108:22": java.lang.NullPointerException
Do you think ii could be an conection error (login, port) or a wrong configuration in my CC?
Thaks in advance,
Daniela Machado

It works fine and have it working with a bunch of other methods but this one gives me this exception. i've even hard coded the variable 'user' and 'albumNumber' with information that exists in the database. i can't see where this logical error is coming from. I appreciate the help. I've been on this for 3 1/2 hour going blind. thanks!!
public boolean updateImageTrackerAlbums(String user, int albumNumber){

Do you understand anyway when a NullPointerException would be thrown? It will be thrown if you try to access/invoke an object reference which is actually null.
Connection conn = null;
pstmt = conn.prepareStatement(query); // Throws NPE because conn is null.

Java.lang.NullPointerException with ADF Module

Hi,
I am trying to build simple application like "How to Build a Simple UIX Search Form
But my view is
=====================================================
SELECT EmIssue.ID,
EmIssue.INITIATIVE_ID,
EmIssue.NAME,
EmIssue.DESCRIPTION
FROM EM_ISSUE EmIssue
=====================================================
And I added new method at AppModuleImpl
It is
ViewObject Issue = findViewObject("EmIssueView1");
System.out.println("***In setBindVars*****");
String WhereClause = " EmIssue.NAME like '%issue%'";
Issue.setWhereClause(WhereClause);
System.out.println("***END setBindVars*****");
Issue.executeQuery();
=====================================================
And the system raises error with java.lang.NullPointerException at line
String WhereClause = " EmIssue.NAME like '%issue%'";
Could any one tell me where is error in my code
Thanks

It is unlikely that NPE was raised on
String WhereClause = " EmIssue.NAME like '%issue%'";
It's more likely that NPE was thrown from
Issue.setWhereClause(WhereClause);
This would happen if Issue is null, which means that the findViewObject() method couldn't find a VO named "EmIssueView1". Make sure that the VO name is spelled corectly. Names are case sensitive.
Thanks.

For more accurate answers, try reposting this question at the RichFaces forum at JBoss.com, there where the RichFaces boys walk around. You see, you're here at a Sun forum where mainly Mojarra boys walk around.

Thank you for reply.
I develop this application in 10.1.3.1.0 ,
I could finally run it on OC4J 10.1.3.1 developer preview in the server , so i have no need to work on running the application on 10.1.3.00 .
but now i have a deep problem with sending emails from my application deployed in production server , i found no solution for it .
it is really ODD in my eyes.
if you are intrested to look at the problem ,
here is its post in OC4J forum , in case that you have experiences , please take a look and advice me for it.

Java.lang.NullPointerException with non admin account in firefox

Hi everybody. I'm new to java and after trying installing JDK 6 and Netbeans I got this exception everytime I visit a site that use java technology :
java.lang.NullPointerException
at com.sun.deploy.net.proxy.DynamicProxyManager.reset(Unknown Source)
at com.sun.deploy.net.proxy.DeployProxySelector.reset(Unknown Source)
at sun.plugin.AppletViewer.initEnvironment(Unknown Source)
This happens only with firefox (IE and Opera works well) and only if I log in a Windows non administrative account.
One month ago everything worked well with firefox. I tried to uninstall JDK anr JRE 6 and reinstall 1.5.11 as well as reinstall firefox. I tried even Gran Paradiso Alpha2, but I got the same exception.
I'm using winxp SP2
What can I do ? Please help me !
Thanks by advance

Try running the java file along with the arg set with the weblogic home
For eg :
java -Dweblogic.home=<path> classname
or
Run the setDomainEnv or CommonEnv.cmd scripts from domain directory or wlserver_home\common\bin directory and then run the java code.
Let me know if it helps

Catching java.lang.NullPointerException with cftry/cfcatch?

I'm getting a java.lang.NullPointerException returned on an
update function in a CFC:
"The cause of this output exception was that:
java.lang.NullPointerException."
I want to find where it's generating this error so I can fix
it. I've never really used CFTRY and CFCATCH, but figured now would
be a good time to learn if this helped me track down the null. Can
anyone provide an example of how to use these tags with the above
NPE and output a message that give info on where it's faulting?
I'm using a standard update query,
<cfquery>
UPDATE table
SET columns = new values
WHERE ID column = some ID
</cfquery>

That was a great tip Dan. Helped me find the line. Apparently
a datatype "date" was given an incorrect null value. I figured the
problem and the update works now :)
Here's code incase someone wants to know:

Tomahawk DataScroller - NullPointerException with navigation panel

Hi all,
I'm trying to implement navigation on a dataTable with DataScroller. Except from the dataTable content the jsp is a copy / paste from the tomahawk cars example.
My jsp structure has 3 main elements
- datatable
- scroller one for datatable navigation (next, previous, ...)
- scroller two for datatable statistics (pages counts)
When page is loaded there is a fatal error (NullPointerException)
If I delete the scroller one definition in my jsp there is no error, data table is correctly populated with 10 first rows and scroller two information is correct.
I tried with a simple ArrayList or with a DataModel in my backing bean. In both cases the NullPointerException happens.
I checked web.xml, faces-config, ... can't find a reason.
Any idea someone please? See stacktrace here under and sample of my jsp
Thank you very much for any help.

Hi all,
I found out a solution (after many hours of cursing!): Better to enclose DataScroller inside a form.
I don't understand why tomahawk example works fine without it (!!!)
If someone has an explanation he is welcome
And if someone explains me how to get more than 24 lines of stacktrace on windows 98 he is welcome too! (Unable to start tomcat from IDE because of wrong memory size), so have to start it from dos...

NullPointerException with MB Subscription With Filter

We basically have xml messages of the form arrive on the MB channel:
<xxx><yyy>111</yyy><zzz>222</zzz></xxx>
<xxx><yyy>999</yyy><zzz>888</zzz></xxx>
and we want our stateful jpd to be only woken up when a message with the text in the <yyy> tag has a value of 999.
In our project we have created a filtered mb subscription control 'jcx', which lead to the following method being created in the interface.
* jc:mb-subscription-method filter-value-match="{value}"
void subscribeWithFilterValue(String value);
The xquery for the 'jcx' looks like:
declare namespace ns0="http://aaa.bbb.com/requests"
data($message/ns0:xxx/ns0:yyy)
In our stateful 'jpd' we basically do the following before waiting for filtered messages on the channel subscription:
mychannel.subscribeWithFilterValue("999");
However, when a message arrives on the channel, we are receiving a NullPointer Exception with the stack trace listed below.
Questions:
1. Is the above the correct way to setup a message broker subscription channel?
2. We are using WLI 8.1 SP2. Does this feature work with SP2 or do we need WLI 8.1 SP3?
3. What are we doing incorrectly?
Thanks much for your time in responding.
Sincerely,
rs

ScoSha,
Thanks for your time in responding. Below are my answers (As) to your questions (Qs):
Q1) You don't have valid XML (if you really meant what you pasted - no root)
A1) The input xml was a snippet representing 2 messages that are in the queue. Sorry, that was not very clear in my posting. That is,
first message in the Q is
<xxx><yyy>111</yyy><zzz>222</zzz></xxx>
second message in the Q is
<xxx><yyy>999</yyy><zzz>888</zzz></xxx>
My intent is to use the Message Broker Channel filtering mechanism to only deliver the second message to my long running process instance. The process instance is only interested in being woken up by messages where the value for the element <yyy> is 999.
Q2)Your Xpath needs to pick one of the 2 xxx/yyy (try xxx[1]/yyy ...OR ->
Q3)your jpd/Xquery seems to have the wrong logic and operations:
A2&A3) In light of my answer to Q1 above, perhaps Q2 and Q3 are not relevant any more.
Objective: In our scenario we have a long running stateful process instance that wants to be woken up when messages with certain dynamically specified data arrive on a Queue. To achieve this we have:
1. created a message broker channel on the queue we are interested in.
2. In the stateful process instance .jpd we create a WLI Filter Subscription control .jcx.
3. The xquery property on this Filter Subscription control is:
declare namespace ns0="http://xxx.yyy.com/requests"
data($message/ns0:xxx/ns0:yyy)
4. In the stateful process instance we execute the following code:
// myVar variable has a value of "999"
mychannel.subscribeWithFilterValue(myVar);
5. Right after the above line we enter the event wait state in the .jpd.
Are steps 1-5 above the correct approach to achieve our objective? If they are, then why would we receive the following NullPointerException? Thanks.

NullPointerException with new ImageIcon

I'm trying to create my first web start application and I'm running into a problem I can't work around. I've written my jnlp file based on the examples in the developer's guide, and it's creating the shortcuts correctly. So far so good.
In my gui code I'm creating toolbar buttons with images, like so:
new ImageIcon(this.getClass().getClassLoader().getResource("javasnap/images/Close24.gif"))
which is exactly what the developer's guide says to do. But I'm getting NullPointerExceptions when my code tries to load the image file:
java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(Unknown Source)
Where am I going wrong?

Alas, case sensitivity bites me again. Thanks.

I also tried it with very simple examples like http://help.sap.com/saphelp_nw04s/helpdata/en/1a/ff773f12f14a18e10000000a114084/frameset.htm , but i still had no luck. On the other hand some simple example with usePdf-mode and a given PDF-source works fine.
Tried enviroments:
- NW 7.0 SP 13 server - NWDS 7.0 SP 9 / Adobe Designer 6.0
- NW 7.0 SP 15 server - NWDS 7.0 SP 9 / Adobe Designer 6.0
- NW 7.0 SP 15 server - NWDS 7.0 SP 13
I thougth it might have something to do with the older versions of the NWDS. But then again i get the same error on various combinations of the enviroment.

I did some more investigations. Probably is the problem, that the IIOP-Service is not running in the dispatcher. I'm getting an exception when i try to start it:
Start service IIOP Provider

I saw another thread with this error, but no solution was provided. Has anybody an idea of the problem, why the IIOP Provider service can't be started?
Thanks
Frank
Edit: I saw some more warnings in the logfiles, obviously the port of the IIOP-service is already in use.
