Java.lang.NullPointerException when capture schema

When I try to capture schema from MySQL (WIN) to Oracle 10G R2 (unix), I have a exeption error: java.lang.NullPointerException
The tables are captured in the repository but columns and others objects don't.
The last line in the java log is:

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?

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.
Here is my code:
public boolean CompExecFile(File filename){
 boolean compRes = false;
 try {
 System.out.println(filename.getAbsolutePath());
 JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
 StandardJavaFileManager fileManager = compiler.getStandardFileManager(null, null, null); //line where I get the error
 Iterable<? extends JavaFileObject> compilationUnits2 = fileManager.getJavaFileObjects(filename);
 compRes = compiler.getTask(null, fileManager, null, null, null, compilationUnits2).call();
 fileManager.close();
 if (compRes) {
 System.out.println ("Compilation was successful");
 } else {
 System.out.println ("Compilation failed");
 } catch (IOException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 return compRes;
 }There error on the line "StandardJavaFileManager fileManager = compiler.getStandardFileManager(null, null, null);":
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException+
I've seen several examples using the parameters "null,null,null" but I don't know if it's good :(
Many thanks for your help.

I've found something which could maybe be what I need to do but I'm not sure:
// Build a new ClassLoader using the given URLs, replace current Classloader
ClassLoader oldCL = Thread.currentThread().getContextClassLoader();
ClassLoader newCL = new URLClassLoader(myClasspathURLs, oldCL);
Thread.currentThread().setContextClassLoader(newCL);
System.out.println("Successfully replaced ClassLoader");
Class fooClass = newCL.loadClass(appClass); //which replaces the line "Class<?> tempFileClass = Class.forName("TempFile");" ?!Is that what I need to do?
EDIT: I've tried that but I still have the same problem:
 File classFile = new File ("TempFile.class");
 ClassLoader oldCL = Thread.currentThread().getContextClassLoader();
 ClassLoader newCL = new URLClassLoader(new URL[] {classFile.toURL()}, oldCL);
 Thread.currentThread().setContextClassLoader(newCL);
 System.out.println("Successfully replaced ClassLoader");
 Class tempFileClass = newCL.loadClass("TempFile");
 Method main = tempFileClass.getMethod("main", String[].class);
 main.invoke(null,new String[0]); Edited by: Foobrother on Jul 28, 2008 8:18 AM

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.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..

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).

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.

Thanks,

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 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

I've found something which could maybe be what I need to do but I'm not sure:
// Build a new ClassLoader using the given URLs, replace current Classloader
ClassLoader oldCL = Thread.currentThread().getContextClassLoader();
ClassLoader newCL = new URLClassLoader(myClasspathURLs, oldCL);
Thread.currentThread().setContextClassLoader(newCL);
System.out.println("Successfully replaced ClassLoader");
Class fooClass = newCL.loadClass(appClass); //which replaces the line "Class<?> tempFileClass = Class.forName("TempFile");" ?!Is that what I need to do?
EDIT: I've tried that but I still have the same problem:
 File classFile = new File ("TempFile.class");
 ClassLoader oldCL = Thread.currentThread().getContextClassLoader();
 ClassLoader newCL = new URLClassLoader(new URL[] {classFile.toURL()}, oldCL);
 Thread.currentThread().setContextClassLoader(newCL);
 System.out.println("Successfully replaced ClassLoader");
 Class tempFileClass = newCL.loadClass("TempFile");
 Method main = tempFileClass.getMethod("main", String[].class);
 main.invoke(null,new String[0]); Edited by: Foobrother on Jul 28, 2008 8:18 AM

E-Rec - java.lang.NullPointerException when creating a VacancyReq thru MSS

Hi,
While i try attempting to create a vacancy requisition thru MSS using start method, "Previous Request", i get to see an "java.lang.NullPointerException" internal server- error in the portal.
When i checked the error log in the backend in ST22, i see the error description given below,
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component (variable: " ").
An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.
When there are many previous requisitions (previously raised) available for the Manager I.D iam testing, iam not sure why this error is showing up,
Has any one faced this issue before? can some one give any clues on the issue iam facing.
Info - I have hidden 2 other start methods available in standard thru configuration (Job & No Reference) from the manager grouping. But i have thorougly checked the configuration and there doesnt seem to be a problem with the configuration as such.
Thanks
G Raj

Hi Raj,
We are also facing the same issue.If you provide us with a solution it would be of great help.
Thanks.

Let me know your suggestions to solve to this.
Your inputs will be appericated.
Thanks,
Sireesha

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).

      JFrame frame = new JFrame("Test frame");
      JPanel panel = new JPanel();
      panel.add(new JLabel("Combobox:"));
      panel.add(new JComboBox(items));
      frame.add(panel);
      frame.pack();
      frame.setVisible(true);
   }The weird thing is that if I execute this piece of code outside my program, in a test class, everything goes fine. I am not sure how this is possible.
Best regards,
Jethro Borsje

You not assign any ActionListener to your ComboBox ?Well, in my real-life implementation I plan to do so, however in the test() method I do not. And the problem is still there in the test method, so to answer your question: no I do not add an ActionListener to the JComoBox in my test case.
A little bit more info: when I scroll in the JComboBox the scrollwheel of my mouse, the scrollbar on the right side does not move, however the contents of the JComboBox does move.
