New row is saving into database correct and application works. What is wrong ? Is it a bug in JDeveloper 10.1.3.2 version. Any patch is aviable? I have found that in 10.1.3.1 it was a bug 5642176 (AWT-EventQueue-0 - NullPointerException
Kuba

Hi,
interesting that this bug is a ADF Swing bug. However, as far as I understand the various updates in the bug DB there is a patch based on Patch Request 9019619 available for 10.1.3.2. For this you need to contact customer support on metalink.oracle.com.
10.1.3.3. is not too far away from now which is why i think going back to 10.1.3.0 doesn't make sense

Hello everyone ... sorry for my English but I am an Italian boy with a problem that is not answered.
I had to create a web application-service (created in Java with NetBeans 6.7) which is connected to a database postgresql (8.3.5) and for connection to the server using tomcat (3.2.4) through SOAP messages (2_2).
OPERATING SYSTEM: WINXP
I have created classes ... I created the database ... completed the project in NetBeans without any errors ... implemented the necessary libraries in the project (also ).... 8.3.604.jar jdbc tomcat configured and soap ... .. and set the environment variables (soap, mail, send in xerces )...... run the application on the NetBeans appears the login screen of my web service .....
enter username and password (exactly!) and the NetBeans gives me an Exception:

                    user.setText("");
                } The strange thing is that this web service was running just finished the project.
After 4-5 days of its operation has stopped, creandomi this problem.
I think the answer is, the server that is not the case.
I thought all I thought was jdbc, but I can connect to the database, so I do not know what to do and how to proceed.
thanks to all, and thanks to my translator. :P

Parameter par = respons.getReturnValue();There is only one possible reason, "respons" is null.

So the problem is given by these two lines, of the Swing-X library:
AutoCompleteDecorator.decorate(expField, exps, false);
AutoCompleteDecorator.decorate(defField, exps, false);
However, the functionality intended from them is given. The problem now seems to do with expField.setText() and expField.selectAll(). I've inline initialized expField, and now it works.

You need to initialize your array:
double [][] expLevels = new double[10][10]; // whatever size.For an array of 'double', all values will be initialized to 0.
It appears that the size of your array can't be known until runtime. You could maybe use an ArrayList of ArrayList of Double objects. Or, if you do know the size (if array_string will have a fixed format), you could use that size.

} Please tel me where is my mistake or maybe you knew another way to open JInternalFrame with public method form another class

Some possibly helpful suggestions:
1) Create one JDesktopPane, and do it in the constructor of GUI. You should call this constructor only once.
2) Get rid of GUII. The GUI constructor will do all this and more.
3) Get rid of startFrame and startFrame2.
4) In GUI2, change your width and height to static variables if you are going to use them in outside classes. There is no reason to have to create a GUI2 object just to get those values. Get them from the class, not the instances.
5) You're doing something funky in your Top class with your mixing of static code and non-static code. My gut tells me that Top is just a static universe that exists to get your code up and running, and that the code within it should all be static, but that's just my personal opinion.
6) In MyInternalFrame, get the height and width from GUI2 (if that's what you want to do) again in a static fashion. Rather than new GUI2().width which makes no sense, use GUI2.width.
Why can't you put the button inside of the JInternalFrame object? I believe that the contentPane of this object which may hold your button (unless you embed a jpanel) uses BorderLayout, so you have to take care how you add jcomponents to the jinternalframe (or more precisely, it's contentPane).

Exception JComboox :Exception in thread "AWT-EventQueue-0" java.lang.NullPo

Hi, I mapped a vector object to the JComboBox. I'm using the observer pattern to update the ComboBox box whenever there is an message receives.If an update is received I just add the data to the vector and to refresh the ComboBox bu calling the UpdateUI() method. When more updates received same time i'm getting the following exception.

Thanks.

I just add the data to the vector and to refresh the ComboBox bu calling the UpdateUI() methodYou should NOT be updating the vector.
That is NOT what the updateUI() method is used for.
The proper way to update a component is to udate the MODEL The model will then notify the VIEW so it can repaint itself. Also, make sure the code is executed on the EDT. Read the section from the Swing tutorial on Concurrency.

I am taking an object from jComboBox as a String and then converting it to integer & adding to the database.
It is not getting added in database to & throwing above exception.

Hello,
First parse the string taken from combo box using Integer.parseInt(str), not directly cast it to Integer.

ASDM Error : Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: ...

I am receiving an exception error when launching ASDM. I have see on the web (and have experienced an issue similar to this before) where a reload resolves the issue. However, I did issue a reload and the error continues. Strange thing is, when I look at the uptime in SH TECH-SUPPORT it shows over a year . Now this firewall is on an active/passive cluster, so my question is, did the reload work on just one and the other took over and so a reload actually did not occur?
We have an issue going on right now where it would be extremely helpful to have this console working.
Thanks In Advance.

Hello Jason,
It could actually be that you reloaded the primary ASA and you are now looking at the secondary(now active) ASA.
do a "show version" and "fail exec mate sho ver" to see the up time for both active and standby ASAs.
You can also try switching to the primary (now standby ASA) using the command "no failover active" and try to access the ASDM again.

Java.lang.NullPointerException in apple.awt.CTextField

Hi,
an applet running for many years fine on a number of Java VMs, suffers a strange problem with the Apple VM. All single-line text fields appear disabled (greyed out). On the Java console, the following exception is recorded:
Exception in thread "AWT-EventQueue-2" java.lang.NullPointerException
at apple.awt.CTextField$1.run(CTextField.java:45)
at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209)

at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:188)
at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)
As you see, this stack trace is obviously related to the problem - I guess, some state-change calls to the TextField are translated into a asynchronous event, whose handler fails. Unfortunately, this trace gives no hint at all, how to work around this problem in the apple.awt.CTextField implementation!
Can anybody give a hint what happens in line 45 of apples CTextField implementation? Can the applet be rewritten in a way to set attributes required by this event handler?
Greetings,
Andreas.

Foo is definatelly null because...
Near the begining of the method foo is initialised to null.
A load of conditional statements follow in only one of which foo is instantiated.
If this condition is not satisfied foo will remain null.
If that happens then you will get the error that you're getting on line 239.
Essentially all the conditions before the above mentioned condition would have to evaluate to false for foo not to remain null by the time line 239 is executed.
Line 239 is executed regardles of any of the conditional statements in your method, i.e. regardless of whether null is instantiated or not, in which case it remains null - hence the NullPointerException.

AWT-EventQueue-0 - NullPointerException

Hello,
did you encounter similar exception in JDeveloper 10.1.3.1?
When I run and use our application in embedded oc4j and then return to jdeveloper I can see few nullpointer exceptions in console window.
We are using ADF BC + ADF Faces but I think the error is related to Jdeveloper IDE.

ok, here's the text, paste it into an empty file called jdevpatch.bat in the same directory as the unzipped files. I've just re-downloaded the patch from Oracle and the file is definately in the zip file so I'm not sure what the problem is (do you have a setting in explorer to hide files with the extension .bat?)
remember, this text is for the 10.1.3.1 patch only!
good luck

Had to un-install JRE, again. "AWT-EventQueue-13" exception.

Hello every body readers,
and a Happy Christmas from me in Sweden.
I installed latest JRE "jre1.5.0_01".
Had to uninstall and use Microsoft java instead, AGAIN.
Those who said to me in past: "Use IE Java. Works better" was probably right.
As now Sun Java only occupies a considerable amont of space in my PC.
You will probably ask me to re-write my HTMLs to fit JRE.
Suppose IExplorer6 wasn't backwards compitable with HTML-pages.
Most .html pages in world would have to be re-written!!!!!!!!!
JRE makes error when trying to update MyClass.class.
"at DJClock.update(E:\Msdev\projects\DJClock\DJClock.java:552)"
A leftover from development stage of this software.
Well!
And this you offer millions of poor users around the world to download?????
Maybe you will not recognize this fault,
and try some political jargong 'we never do anything bad" non-excuse.
I would simple say: "we are very sorry!" to all potential users reading this thread.
We humans are NOT perfect. When try to appear perfect, we deny the truth.
And we would not be credible in fellow men's eyes.
Isn't it pathetic hear someone say:
"I did not have seex with that woman"
when it is obviously a big lie. :D :D
I hope you're human at this developers site.
I have a slight hope some few around here
are not only "living effective programming robot machines".
Regards and thanks for your FREE, although not working software
/halojoy - Sweden 2004-12-29
FACTS follows:
In my htdocs:
APP1-folder
     MyClass.class
     index.html(<applet codebase="." code="MyClass.class"</applet>)
APP2-folder
     MyClass.class
     index.html(<applet codebase="." code="MyClass.class"</applet>)
Uses same class, but I have copy at 2 places.
First applet will run correctly.
Second applet will generate following message:

Thanks, alvareze.
But I think you haven't read my post correctly.
I think I provided enough information for eanyone to repeat my situation in their own computer.
Anf find out there is a bug.
I wish I was wrong, on behalf of users suffering from this,
but I am sure I am right!
So here is what you do.
1) Take an applet, xxxxxx.class, intended for showing in a html-page.
2) Create 2 folders at your server. Lets call them: APPL1 and APPL2
3) Write 2 different index.html containing applet xxxxxx.class
4) You make a copy of this Class: xxxxxx.class in EACH of two folders APPL1, APPL2
5) Each index.html in separate folders Calls their own copy of xxxxxx.class
in respective folder.
6) The structure you have now is, what I ALREADY told you. (am I talking to children. No!):
In my htdocs:
APP1-folder
     MyClass.class
     index.html(<applet codebase="." code="MyClass.class"</applet>)
APP2-folder
     MyClass.class
     index.html(<applet codebase="." code="MyClass.class"</applet>)
6) Now you can visit your both websites:
- http://root/APPL1/index.html
running applet.
Then visit
- http://root/APPL2/index.html
running same applet.
And I am sure you will end up with same error message.
AWT-EventQueue-13" exception.
(see Above. And below. LISTEN CAREFULLY, I will only say this TWICE):
Uses same class, but I have copy at 2 places.
##) My EXPLANATION:
possibly causing this error, and making JRE useless for me:
When JRE runs into a Class with same name again,
it will update that class in its library.
But when it does it searches, STILL, in the developers Drive E:\
A leftover code, from developing stage.
Instead JRE should look for MyClass.class in drive where,
I put JRE files. In this case Drive C:\
##) In other words:
- at MyClass.update(E:\Msdev\projects\MyClass\MyClass.java:552)
should be, to avoid error
- at MyClass.update(C:\my path to JRE\MyClass\MyClass.java:552)
##) First applet will run correctly.
##)Second applet will generate following message:
Exception in thread "AWT-EventQueue-13" java.lang.NullPointerException

I wont bother with this again,
as I do not like to explain myself over and over
to people that are not REALLY interested in getting my information.
And it will not effect me in any way, as I no longer use this free JRE from great Sun Java Laboratories.
I stick to Microsoft Java, until you find your bugs, yourselves, fixes this software version.
Then you tell me to download it again, please!
Thanks again for you wish to provide us users with a super software.
nothing wrong with your aim or goal, but ...
maybe can strike back, when releasing not properly debugged sotware
to millions and millions of potential users.
Better no reputation, than bad reputation= badwill.
So sometimes better late release than too early.
Have seen this happen with other software version around www.
By the time bugs are corected, customers are happily using another similiar software.
No hard feelings.
Happy Ne Year everybody!
computer and internet freaks, like me

How to handle the exception in AWT-EventQueue-0?

This is my code:
import javax.swing.JFrame;
public class MainFrame extends JFrame {
     public MainFrame(){
          init();
     public void init(){
          setSize(100,100);
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
public class SubFrame extends MainFrame implements ActionListener{
     private JButton button1 = null;
     public SubFrame(){
          super();
     public void init(){
          super.init();
          button1 = new JButton("button1");
          add(button1);
          button1.addActionListener(this);
     public void actionPerformed(ActionEvent e) {
          // TODO Auto-generated method stub
          button1.setEnabled(false);

Hmm. Interesting sequence of execution.

and only after all these calls return, the declaration-cum-assignment of button1 is executed, which makes button1 null.
(Discovered by putting a breakpoint on that line and debugging in NetBeans)
With one change, button1 will not be null and the breakpont is not reached.private JButton button1;// = null;What's not clear is why the declaration-cum-initialization takes place after the constructor code executes, shouldn't it run before the constructor?
It does run before the SubFrame constructor, but it runs after the super class constructor, which is exactly how the language specification says it should be.
There was a similar thread a while back:
http://forum.java.sun.com/thread.jspa?threadID=5190252&messageID=9745092
Note that there is another "bad" habit involved (other than explicitly initializing member variables to null): that an overridden method is called from the super class constructor. That means that the overridden method will be executed before the object it belongs to has been fully initialized, and that will often lead to confusing behavior like this.
