Java.lang.NullPointerException when trying to preview an iVew in EP

We have set up a portal federation with a BI portal as the producer and a enterprise portal as the consumer. When we try to do a preview on iView which is based on BW 7 based contents from producer portal, we get java.lang.NullPointerException. The 3x based reports are being displayed fine on the consumer side. I have put excerpt from the default_trace from producer portal that gives some error messages but I am not able to figure out where the problem might be.
Any help is greatly appriciated.
Thanks

Java.lang.NullPointerException when trying to compile

Hi everybody!
I'm trying to compile a file using javax.tools.JavaCompiler but I get a java.lang.NullPointerException when running the program.

Java.lang.NullPointerException when trying to start UM

I get java.lang.NullPointerException when I try to start Unified Messaging using EM on a new Windows 2000 single-box installation. Has anyone enountered this problem?

I have also encountered same issue. Please let me know the solution in case you find it.
In fact after configuiring Oracle files as per the document provided at Oracle OTN site 'Collaboration handbook', I am unable to connect OID. As per log it says
2003/04/01:20:37:58[Oidmon]: Unable to connect to database, will retry after 20 sec
2003/04/01:21:20:21Starting Monitor Process, PID=2920

2003/04/01:21:41:22Failed to fetch Process Table. ORA-12571: TNS:packet writer failure
I checked Listener, which was found ok, then I checked TNSPING, which executed ok.
I have dowloaded documents troubleshooting OID, but no success. The document itself says that architecture of OID is fairly complex and the log does not suggest much insight.
Any solution?

please let me know if you have configured any RPS for the same.i faced a similar issue while i was trying to create an instance taken from oracle export dump taken from one of our client.our error got resolved when we changed the web profile to PROD. More often than not this is an issue with the webprofile. try changing the web profile one by one from dev to test to prod and kiosk.
if none of these resolves the issue, try ruuning version app engine program. this will update the ppltools version. in correct version may also some times cause this issue.
Please let me know if you have configured ldap.

Java.lang.NullPointerException when doing SQL on ms access

I am trying to perform Insert and delete commands on an access database and I continue to get a java.lang.NullPointerException when performing the action. Everything is fine when i do a Select * FROM..., I am able to read all of the information I ask for, but when performing the Insert/Delete commands I get the error. Any help would be appreciated, I will copy and past a portion of my code below. All of the fields and variable types match with what is in the database.
public void executeAddSecretary() throws SQLException{
String a,b;
a= txtSecLname.getText();
b= txtSecFname.getText();
statement.execute("INSERT INTO Contact_Sec (Sec_Lname,Sec_Fname) Values ('" + a + "', '" + b + "')");
System.out.println("updated Secretary");
public void executeDeleteContact() throws SQLException{
String a = "a";
statement.execute("DELETE FROM Contact WHERE Lname = ('" + a + "')");
System.out.println("deleted contact");
Thanks to anyone who can help me out.

1) Use prepared statement instead of statement.
2) Do like this ...
PreparedStatement prepStmt = null;
try
     String query="INSERT INTO Contact_Sec (Sec_Lname,Sec_Fname) Values (?,?)");
     prepStmt = connection.prepareStatement(query);
     prepStmt.setString(1, value1);
     prepStmt.setString(2, value2);
     prepStmt.executeUpdate();
catch (SQLException e)
     throw e;
catch (Exception e)
     throw e;
finally
     try
          if (prepStmt != null)
               prepStmt.close();
     } catch (Exception e) {}
     try
          if (connection != null)
               connection.close();
     } catch (Exception e) {}
}3) If you still get the null exception then put step wise System.out's
and debug it.

Java.lang.ClassCastException when trying to retrive a jdbc/OracleDS

Hello friends, I'm experiencing a rare problem, "java.lang.ClassCastException" when trying to retrive the jdbc/OracleDS datasource using JNDI lookup, the exception is there, either, when running in the embebed OC4J from JDev 10.1.3.3 or when deploying (the War) to my OracleIAS (10.1.2). Actualy we are programing the DataSource and changing the URL each time we update the application (in both environment: Developer and Production), it is just a temporary "work around" while we find the real solution.
We can't Cast a Oracle Object (oracle.jdbc.pool.OracleDataSource) to the java DataSource. Why?
Here you have the story:
The application wa started in Eclipse 3.2 with Tomcat 5, and we are using Struts 1.1 and Hibernate 3, in this environment we don't have problems. the problem happens during deploying the application to our Orace AS 10g (10.1.2). When googling for solution we found related problems in some forums, so we tried all the solutions explained in that post, including this. Finaly, we failed to find the solution.
After that, we migrate the application to JDeveloper 10.1.3.3, and then try the JNDI lookup and the problem STAY, then we did everything again into JDev:
- Changed the default jdk from 1.5 to 1.4.2_06, for the projects, the embebed OC4J and the Java Compiler....
- Configuring the DataSource manualy in the xml.
- Testing with several jdk version, trying on embebed oc4j, standalone oc4j, Oracle IAS, and so on.
- We have tried everything we found in the posts.
But .... the problem still :'(.
We have found that some guys have solved the problems with the change of the jdk and other small stuff, but all that were not enough for us.
Have somebody found other solution for this problem or we have some alien problem here?.
Thanks in advance.

Fer Domin, thanks by your replay.
The answer for your question is, YES. We have tried with several DataSource types in the Oracle side (app server,embebed oc4j, standalone oc4j) and the app side (java). Also, all jdbc datasource extend the javax.sql.DataSource .. so it's rare to have this error when doing a simple jndi lookup.
We tried deploying a small app (from Oracle) to test the DataSource in the app server (10.1.2.0.2) and it was working well. But we don't know which jdk was used to package that ear/war (I mean the TestDS small app).
So, everything look like we are having a jdk compatibility problem ... but we don't know which it's or where it's.... because we configure JDeveloper 10.1.3.3 to use the same jdk, even for compiling and running the embebed oc4j and the problem still.
Thanks again.

Urgent - java.lang.NullPointerException when deploying a WAR file

Hello
I am trying to deploy a WAR file on 9iAS rel 2 using the Enterprise Manager. On the web page, I provide the .war file along with application name and url mapping. When I click on deploy, i get an error back which just says java.lang.NullPointerException. There is no stack trace.
Until now, I have been working on my own PC using tomcat, and the war file works fine in tomcat.
I am presuming that there will be a log file where more information will be available, but I do not know where the log file is kept. The Oracle 9iAS is installed on Solaris.
Any help with this would be greatly appreciated.
Thanks.
Jay

Problem Solved
The problem was the web.xml file which contained some elements that are only valid for servlet 2.4 (used on tomcat) but not on 2.2(used in oracle).

Hi Sireesha.
This exception means that you don't have enough permissions to edit the master rule collection. Add your user to a super admin user group or, if it is not applicable due to your company policy, provide full control rights (not only read/right).

Java.lang.NullPointerException when attaching a custom LOV

I've created a new LOV and import it. Then I've personalized an existing page by creating a new messageLovInput field and set its external LOV properties to my custom lov and definde the mapping. I get the following when calling my lov : "oracle.apps.fnd.framework.OAException: java.lang.NullPointerException
at oracle.apps.fnd.framework.OAException.wrapperException(OAException.java:888)
at oracle.apps.fnd.framework.webui.OAPageErrorHandler.prepareException(OAPageErrorHandler.java:1145)".

Hi,
I am trying to accomplish similar kind of thing i.e. dislaying custom LOV on iProc requisition checkout page...I'll appreciate if you can clarify me on the steps involved.
I am confused if PERSONALIZATION can acheive this on its own or Jdev is needed aswell?

Other times, it works fine. Anything I might have done wrong in installing this guy? Any thoughts?
Thanks, Michael

I'm agree ... His behavior is very strange.
At the first time, I decompressed zip file into a new dir and at the first run I agreed to import setup from previous version. From the beginning the v2.1 worked wrong.
After that, I removed all, new and previous versions. I deleted sqldeveloper folder and also service folder (under \Documents and Settings\...\Application data\...)
Also I searched into registry ...
Nothing to do ... also new installation hangs ...
So, perhaps I have to wait new release ... (perhaps the exceptions or the environment conflict will be fixed).
Thanks again.
Regards.
PS: Please, if you have other suggestions, let me know. Many Thanks.

Error: java.lang.nullPointerException when process is complete

Hello,
I keep getting the below error in the log file when the process is complete, does any one has this error before? The error does not affect the process but it is kind of annoying when looking at the log file. I try to use the other component beside the Foundation>DecisionPoint>execute but I still get the same error.
[5/16/11 14:57:19:047 CDT] 00000047 AWS E com.adobe.workflow.engine.ProcessEngineBMTBean stallAction stalling action-instance: 40746 with message: javax.ejb.TransactionRolledbackLocalException: ; nested exception is: java.lang.NullPointerException
Can any one please advise on how to fix the error above to stop showing in the log file. I am still using LC ES 8.2.1 with SP3.
Thanks,
Han Dao

If you could give a little more info it would help. The web.xml for example, if your mapping it correctly, etc...

Java.lang.NullPointerException when writing to a textfield..help please?

Hi guys,
I'm getting a java.lang.NullPointerException (with no other details of error) when i try to write to a textfield on my GUI. the line: TF1.setText("F"); is where the problem is occurring. that line is within a loop ->
 if(freq >87 && freq < 100)
 System.out.println("Note =F" +freq);
 TF1.setText("F");
the textfield has been constructed and initialised and given an initial value. what i need to happen is the string in the textfield to be constantly updated (overwritten) with the new string.
the initial value from TextField TF1= new TextField("", 10);
TF1.setText("blank");
works fine, but one the loop above is entered, the current frequency is printed to the command line and then "java.lang.NullPointerException" is thrown.
I'm struggling with this, and have a deadline to meet so I would much appreciate some help.

The Gui class is this:
import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.Panel;
import java.awt.TextField;
import javax.swing.JFrame;
import javax.swing.*;
public class Gui extends JFrame{
public static void main(String args[])
Project project = new Project();
project.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
 project.setSize( 250, 200 ); // set frame size
project.setVisible( true ); // display frame
// new Project(){//constructor
 Panel p, p1;
p = new Panel();
 p.setLayout (new FlowLayout(FlowLayout.LEFT,5,5));
 project.add(p, BorderLayout.NORTH);
 p1 = new Panel();
 p1.setLayout (new FlowLayout(FlowLayout.LEFT,5,5));
p1.setLayout (new GridLayout(4,1));
project.setTitle("Guitar Tuner Prototype");
 TextField TF1= new TextField("", 10);
TF1.setText("blank");
 p1.add(TF1);
 TF1.setVisible(true);
 p1.setVisible(true);
 p.add(p1);
//Capture input data from the microphone
project.captureAudio();
project.captureThread();
}//end constructor
//end main
The project.java class has the "private TextField TF1; at the top. the project.java class also contains the loop thats writing to the texfield as specified in th original post..
