Dear balaji,
There is still some errors in templates about creating new pages under staging area, i recomend you to use only templates with
three containers or four containers. i probed those ones and i didnt have problems, by the way in some cases when you use two containers you could be fine, but the problems appears when you try to edit the content...because the error you mentioned appears again!

Exception occured during Event Dispatching

Hi,
I am getting the following error,
Exception occured during Event Dispatching:
java.lang.NoSuchMethodError:java/net/URLEncoder.encode(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
at getURLPostString2.<init> (bytecode 552)
at getURL2.<init> (bytecode 200)
at testFrame.actionPerformed(bytecode 224)
at java.awt.Button.processActionEvent(bytecode 12)---- --
I initially had URLEncoder.encode() method in getURLPostString2.java then i removed that method from that class itself. i have the right method now in testFrame.java, there is an other class called fetchURL.java which uses the same method and it doesnot throw any exception. but the same exception is occuring in getURLPostString2.java even when i removed encode method from getURLPostString2.java. i have done all the necessary stuff like saving it and recompiling it but still the problem persists
i am using jeode evm to compile my java files
why is this weird problem occuring even when we have removed that method.

That is kinda odd. Did you try deleting the old .class files first? Cuz if you delete the old class files and then recompile and still get the error than I would have to guess that you didn't fix the proble. Maybe you have some old code lying around that is still trying to call an old method? Maybe you have fixed the file with the wrong methods in it but not fixed the file that called those methods? That actualy seems to be right because a NoSuchMethodError really aught to be caught at compile time because the compiler checks to be sure all the calls you make actualy exist.

Sender Mail Adapter Error: exception caught during processing mail message;

HI , I am configuring mail to file scenario. Need to read mail content (no need to capture From,TO or Subject details) and create a file with the content in the mail.
Need to read mails from microsoft outlook. Exchange server has been configured for POP3 protocol.
Following are the details provoding in sender mail adapter:
URL: provided url in the format: pop://<server name>
Authentication method: plain
provided user credinetions to access mails.
poll interval - 1min
content encoding none.
processing parameters : quality of service-exactly once
Since there is no need to capture From,TO or Subject details, didn't select the option - use mail package.
Verified for unread mails in the mail box and made sure that there are few unread mails.
Also, created data types and other components in IR and completed mapping.
But after starting sender mail communication channel, getting error "exception caught during processing mail message; java.lang.NullPointerException" in RWB-adapter-communication channel monitoring.
please let me know what needs to be done to resolve this error.
Thanks.

HI Stefan, i tried, but still it is giving same error. Yes, i am able to access outlook mail with the user credentials given in the communication channel to access exchange server.
I am using message protocol: xipayload . Also since i dont have to capture TO,from,subject details., created data type just with one element of type string, not in the standard format .Does this makes any difference.

Information Regarding :Exception occurred during event dispatching

Hi,
I frequently get this exception when I click a button in a dialog and it opens up another frame of window. The exception trace includes java internal classes and my program classes line numbers. I have searched the net but could not get any concrete answer.
Is this problem in java packages or should we take care of something in our code to avoid such exceptions.
Below is the exception trace..........................

Hi All,
Thanks for the replies and information posted by you.
Below is some code snippet: ( complete code posting is difficult) ;-)
Dialog1 is open, clicking on button say start it hides the current Dialog1 and opens the status dialog for Dialog1.
Also, we are making the current Thread to sleep to avoid flickering.
dialog1.hideWindow(); // Hide current window...
Thread.currentThread().sleep(5); // sleep to avoid flickering..
statusDialog.showWindow(); // to display status window..
I will check and try to do modifications as per your suggestions.
Thanks.

JFileChooser : Exception occurred during event dispatching

Hi,
I'm having problems with sorting in 'Details' view of JFileChooser. I'm getting the following NullPointerException when I try to sort by clicking on the header of the JTable which I get in 'Details' view of a JFileChooser.

Any operation performed in the JFileChooser after this exception will generate the same exception & no action is performed. I'm using Java 1.6.0_24. Strangely, this is happening only in client-server mode. Staand-alone is working fine.
Please provide some urgent inputs to this problem
Thanks
Dilip

Thanks 4 d reply mKorbel, I'm not creating a TableModel. I'm just creating a JFileChooser as shown below.
JFileChooser fileChooser = new JFileChooser(location);
fileChooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
fileChooser.setMultiSelectionEnabled(false);
fileChooser.setDialogTitle("Choose File");
if (fileChooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION)
Now, the scenario is to bringup the FileChooser, go to Details view, apply sort on any column. This action creates the mentioned NullPointerException.

Fix the NullPointerException. The stack trace tells you the line that caused the problem.

read the following configuration i hope it will help u.
How to get up and running with WebUtil 1.06 included with Oracle Developer Suite 10.1.2.0.2 on a win32 platform
Solution
Assuming a fresh "Complete" install of Oracle Developer Suite 10.1.2.0.2,
here are steps to get a small test form running, using WebUtil 1.06.
Note: [OraHome] is used as an alias for your real oDS ORACLE_HOME.
Feel free to copy this note to a text editor, and do a global find/replace on
[OraHome] with your actual value (no trailing slash). Then it is easy to
copy/paste actual commands to be executed from the note copy.
1) Download http://prdownloads.sourceforge.net/jacob-project/jacob_18.zip
and extract to a temporary staging area. Do not attempt to use 1.7 or 1.9.
2) Copy or move jacob.jar and jacob.dll
[JacobStage] is the folder where you extracted Jacob, and will end in ...\jacob_18
cd [JacobStage]
copy jacob.jar [OraHome]\forms\java\.
copy jacob.dll [OraHome]\forms\webutil\.
The Jacob staging area is no longer needed, and may be deleted.
3) Sign frmwebutil.jar and jacob.jar
Open a DOS command prompt.
Add [OraHome]\jdk\bin to the PATH:
set PATH=[OraHome]\jdk\bin;%PATH%
Sign the files, and check the output for success:
[OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\frmwebutil.jar
[OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\jacob.jar
4) If you already have a schema in your RDBMS which contains the WebUtil stored code,
you may skip this step. Otherwise,
Create a schema to hold the WebUtil stored code, and privileges needed to
connect and create a stored package. Schema name "WEBUTIL" is recommended
for no reason other than consistency over the user base.
Open [OraHome]\forms\create_webutil_db.sql in a text editor, and delete or comment
out the EXIT statement, to be able to see whether the objects were created witout
errors.
Start SQL*Plus as SYSTEM, and issue:
CREATE USER webutil IDENTIFIED BY [password]
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp;
GRANT CONNECT, CREATE PROCEDURE, CREATE PUBLIC SYNONYM TO webutil;
CONNECT webutil/[password]@[connectstring]
@[OraHome]\forms\create_webutil_db.sql
-- Inspect SQL*Plus output for errors, and then
CREATE PUBLIC SYNONYM webutil_db FOR webutil.webutil_db;
Reconnect as SYSTEM, and issue:
grant execute on webutil_db to public;
5) Modify [OraHome]\forms\server\default.env, and append [OraHome]\jdk\jre\lib\rt.jar
to the CLASSPATH entry.
6) Start the OC4J instance
7) Start Forms Builder and connect to a schema in the RDBMS used in step (4).
Open webutil.pll, do a "Compile ALL" (shift-Control-K), and generate to PLX (Control-T).
It is important to generate the PLX, to avoid the FRM-40039 discussed in
Note 303682.1
If the PLX is not generated, the Webutil.pll library would have to be attached with
full path information to all forms wishing to use WebUtil. This is NOT recommended.
8) Create a new FMB.
Open webutil.olb, and Subclass (not Copy) the Webutil object to the form.
There is no need to Subclass the WebutilConfig object.
Attach the Webutil.pll Library, and remove the path.
Add an ON-LOGON trigger with the code
NULL;
to avoid having to connect to an RDBMS (optional).
Create a new button on a new canvas, with the code
show_webutil_information (TRUE);
in a WHEN-BUTTON-PRESSED trigger.
Compile the FMB to FMX, after doing a Compile-All (Shift-Control-K).
9) Under Edit->Preferences->Runtime in Forms Builder, click on "Reset to Default" if
the "Application Server URL" is empty.
Then append "?config=webutil" at the end, so you end up with a URL of the form
http://server:port/forms/frmservlet?config=webutil
10) Run your form.
If its Correct/Helpful please mark it thanks.
Sarah

Here is also a small sample piece of code that makes it happen too. Whever I "hover" over the button this occurs.
public class Test
public static void
main(String[] argv)
throws Exception
// set up GUI
JFrame frame = new JFrame();
frame.setBounds(0, 0, 100, 100);
JPanel panel = new JPanel();
frame.getContentPane().add(panel);
panel.setLayout(new BorderLayout());
panel.add(new JButton("Push me"), BorderLayout.NORTH);
panel.add(new JLabel("Hello world"), BorderLayout.CENTER);
frame.pack();
frame.setVisible(true);
return;

In the case of this problem, it happens EVERY TIME I run the application (and happens with Swingset too) and it DOES affect the application. I can't click on buttons, etc. All swing events seem to generate this trace back. I tried recompiling all the code thinking I might have a bad class file or something, but to no avail. Could this be a version mis-match? I'm running Linux 6.2.

Exception occurred during event dispatching: Null pointer exception

All,
i have an applet which opens an applet window. in this applet window i have a list box.
When a value in the list box is selected, i need to access a method in the applet(held in another class) that launches another window
however i get the following error:
Exception occurred during event dispatching: Null pointer exception
(hope thats clear enough)
p.s. i have created an instance of the class.

That is not clear at all, but the cause for the exception is very easy:
something is null that should not be null :)

Hi,
I' m getting an error while connecting to database ORACLE 9i.
I'm using JDK 1.6.0
Actually the code is about how an Japplet connects to database ORACLE 9i
when i was connecting using normal program i had got the connection easily .
When i used this JApplet ,i'm getting this error.
CODE:
import java.awt.*;
import javax.swing.* ;

public class jln extends JApplet
public void init()
JTabbedPane jtp=new JTabbedPane();
jtp.addTab("View Marks",new VmPanel());
getContentPane().add(jtp);
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
} catch (Exception e)
{ e.printStackTrace();
System.out.println("Failed to load driver.");
class VmPanel extends JPanel implements ActionListener
JButton b1,b2;
TextArea ta1;
JTextField jtf1;
Connection con=null;
public VmPanel()
b1=new JButton("ok!");
b2=new JButton("clear");
ta1=new TextArea();
jtf1=new JTextField(10);
add(jtf1);
add(b1);
add(b2);
add(ta1);
b1.addActionListener(this);
b2.addActionListener(this);
public void actionPerformed(ActionEvent ae)
String str1=ae.getActionCommand();
if(str1=="ok!")
try
con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:jlngbldb", "scott", "tiger");
Statement stmt = con.createStatement ();
String ht=jtf1.getText();
System.out.println("\nHello\n");
ResultSet rs = stmt.executeQuery("SELECT * FROM jln WHERE ht='"+ht+"'");
while(rs.next())
ta1.setText ("");
ta1.setText("Name:"+rs.getObject("name")+"HallTicket:"+rs.getObject("ht")+"C.G:"+rs.getObject("cg")+"C.D:"+rs.getObject("cd")+"UNIX:"+rs.getObject("unix")+" S.T.M:"+rs.getObject("stm")+"N.N:"+rs.getObject("nn")+"I.S:"+rs.getObject("ins"));
rs.close();

con.close();
catch(SQLException ex)
System.err.println("SQLException: " + ex.getMessage());
if(str1=="clear")
ta1.setText("");
jtf1.setText("");
if(str1==null)
ta1.setText ("");
ta1.setText("Please enter Hall Ticket Number above....");
}//action performed close

I'm getting this error when i pressed the OK! JButton.
PLEASE ! help me by correcting this error.
Thank You.

Presumably you are running this via a browser where the applet is served from the server.
Applets can only connect back to the origination server and using the name that the origination server was accessed with.
And that has nothing to do with JDBC, all connections work that way.
Your driver uses a connection thus it will not work unless it attempts to connect to the server that originated the applet.
Solutions
1. Connect to the server
2. Sign the applet
3. Modify the policy file of each client that will run the applet. This is not a good idea in an unsecure network.
Note as well that in an unsecure network is most often a bad policy to have an applet directly accessing a database regardless.

In your test.java (Which must be yours, since all serious classes have capitalised names) you are trying to load a JNI library with
static {
System.loadLibrary("test");
}Somewhere you should have a library file, I think called libtest.so, but the JVM can't find it.
Find out where it is and put -Djava.library.path=<the directory>
on the java command.

Exception occurred during event dispatching

I'm facing a problem with dispatchCustomEvent() method while clicking a button on oracle form. The code is given below:
package oracle.forms.finalbutton;
import java.awt.*;
import java.awt.event.*;
import java.util.StringTokenizer;
import javax.swing.JButton;
import oracle.forms.ui.CustomEvent;
import oracle.forms.ui.VBean;
import oracle.forms.ui.VButton;
import oracle.ewt.button.PushButton;
import oracle.forms.handler.IHandler;
import oracle.forms.properties.ID;
import oracle.forms.properties.Property;
public class FinalButton extends VBean implements ActionListener
public final static ID WBP = ID.registerProperty("BUTTONPRESSED");
private IHandler m_handler;
protected JButton b1 ;
public FinalButton()
super();
b1 = new JButton("");
b1.setActionCommand("push");
b1.addActionListener(this);
add(b1) ;
public void actionPerformed(ActionEvent e) {
CustomEvent ce = new CustomEvent(m_handler, WBP);
// new URLProcess("http://rsb.info.nih.gov/ij/images/ct.dcm");
new URLProcess("http://localhost/Sunset.jpg");
dispatchCustomEvent(ce);
public void init(IHandler handler)
m_handler = handler;
super.init(handler);
The exception message thrown is given in the subject of this message. Now I need to know the details regarding event dispatching. Please someone help me.
Thanks

Hi
Thanks...actually I want to click a button on Oracle Form and below is the actionPerformed method code:
public void actionPerformed(ActionEvent e) {
CustomEvent ce = new CustomEvent(m_handler, WBP);
new URLProcess("http://rsb.info.nih.gov/ij/images/ct.dcm");
dispatchCustomEvent(ce);
I think my way of event dispatching isn't right. I need to instantiate an object of the class
URLProcess on click event. Could you please let me know how can I get around the problem?

Ajay,
You was right to some extent...We have started the ADS Web service.
