NullPointerException when using JEditorPane
I use a JEditorPane to show html in an applet, when I try to load the JEditorPane from an InputStream I get a NullPointerException.
Stacktrace:

The file I load just contains "<html><body>Test</body></html>", I am loading it using url.openStream();. The file is below the codebase and the url is correct.
Tell me if you need more information.
The HTML you say you are trying to use is not technically well-formed. I think you need to include the <head> tag here. All CSS information must be located there, and I am assuming that the parser is looking for this info since it is dying in javax.swing.text.html.StyleSheet.

Weblogic throws NullPointerException when using ServiceControl.setTimeout
We are invoking a SOAP service via a com.bea.control.ServiceControl that was generated from a WSDL (right click WSDL, Generate Service Control) using Weblogic 8.1.6.
SOAP service execution is successful using an http and https endpoint. However, when setting a timeout via ServiceControl.setTimeout(int millisecods) method, the Weblogic API is throwing a NullPointerException when using an https endpoint. When using an http endpoint with the setTimeout method execution is successful.

NullPointerException when using sharedNode in XML menu (jdev 11.1.1.3)
I am using Jdeveloper 11.1.1.3 and when I use a sharedNode in my ADF XMLMenu, I get a NullPointerException when I start the application for the first time. I know it's the sharedNode because when I remove it i don't get the exception.
Apparently something is not propertly initialized at startup, when I reload the page everything is fine. How can I fix this?

I also have nested templates and in the outer template I had a breadcrumb referencing the sharedNode menu. Somehow this caused a NullPointerException. The breadcrumb was never meant to reference that menu in the first place so I changed it, but it is still a weird situation, maybe worth a testcase...

Java.lang.NullpointerException when use source table as a mapping component
Hi all,
I am new to owb and I got NullPointerException when I try to drag a table to my mapping.
The table is imported and it's from a windows oracle database. The mapping is located on my linux oracle database.
By the way, I can even deploy the table.
What have I done wrong and why this happen?
thanks in advance.
帖子经 953800编辑过Hi Timo,
Thanks for the reply,
If I understand correctly I need to apply to the weblogic server 10.3.5 + Sherman patch UPDATE1 patch #12979653 and patch #12917525. After this the ADF Runtime 11.1.1.5 installed in the Production environments will allow me to run my application that is running in ADF Runtime 11.1.2.1. right?
I'm working on getting this patches installed. Thank you very much for your help.
I run the test on my local server as a test class and as a web service, it worked perfect, nevertheless in the Production environment I got a interesting answer:

cipher.init(Cipher.DECRYPT_MODE, pk);IMHO RSA is 2-keys algorithm => you cannot use it in cipher class
If u need encrypt use PBE for example
PBEKeySpec pbeKeySpec;
PBEParameterSpec pbeParamSpec;
SecretKeyFactory keyFac;
// Salt
byte[] salt = ...;
// Iteration count
int count = 20;
// Create PBE parameter set
pbeParamSpec = new PBEParameterSpec(salt, count);
// Prompt user for encryption password.
pbeKeySpec = new PBEKeySpec(pass); //String with
keyFac = SecretKeyFactory.getInstance("PBEWithMD5AndDES");
SecretKey pbeKey = keyFac.generateSecret(pbeKeySpec);
// Create PBE Cipher
Cipher pbeCipher = Cipher.getInstance("PBEWithMD5AndDES");
// Initialize PBE Cipher with key and parameters
pbeCipher.init(Cipher.ENCRYPT_MODE, pbeKey, pbeParamSpec);
// Our cleartext
byte[] cleartext = "This is another example".getBytes();
// Encrypt the cleartext
byte[] ciphertext = pbeCipher.doFinal(cleartext); -
NullPointerException when using Scanner
Hey people,
I've made this little class for interacting with the user via the console:
package dyreleg;
import java.util.Scanner;
* Communicates with the user via the command line
* @author majs
public class ConsoleUI implements UserInteraction {
private Scanner input;
public void ConsoleUI() {
this.input = new Scanner(System.in);
* Asks the user a given question and returns the answer as a string
* @param question the question to ask the user
* @return the users full answer
public String getAnswer(String question) {
System.out.println(question);
String answer = this.input.next("\n");
input.nextLine();
return answer;
* Asks the user a given question and forces him/her to answer with either y
* for yes or n for no.
* @param question question the question to ask the user
* @return the users answer, true for yes and false for no
public boolean getAnswerYesNo(String question) {
System.out.println(question+" (y or n");
while (true) {
String answer = this.input.next();
answer = answer.toLowerCase();
if (answer.equals("y")) {
return true;
} else if (answer.equals("n")) {
return false;
} else {
System.out.println("You must answer y for yes or n for no to the given question");
}My problem is that when i try to use any of the member functions, (getAnswer and getAnswerYesNo) i get a NullPointerException, and i can't understand why. I know that NullPointerExceptions indicate that the variable isn't set to an object, but as far as i can see that does'nt seem to be the problem here. I've used the Scanner class without problems in the rest of my application before making this class without problems.
Any kind of help is appreciated.Meinertz,

But i think that when i run my servlet that the init method is not used. I believe the problem is the access to the database.
Thanks for the answer because i'm beginning to hate the cobalt server at my school -
Help needed to handle vbscript when using JEditorPane
Dear ppl,
Reading about JEditorPane and rhino it seems like that javascript in a html file rendered on a jeditorpane can be handled using rhino. Now is there any out to do the same thing for vbscript?
Thanks in advance.Hi
You can use Modification groups while declaring the buttons. Assume we assign group1 as B1 for button1 and B2 for button 2.
fcode for button1 as BUT1 and fcode for button2 as BUT2.
at pbo
if sy-ucomm = 'BUT1'.
loop at screen.
case screen-group1.
when 'B1'.
screen-active = '0'.
modify screen.
when 'B2'.
screen-active = '1'.
modify screen.
endcase.
endloop.
else.
loop at screen.
case screen-group1.

NullPointerException when using setBindingContext
Hello,
I'm having some trouble instantiating a JFrame that has data binding.
When i instantiate the JFrame in an other class in the same project as the JFrame it works.
But when i try to instantiate it in a class in an other project (still in the same workspace) it doens't work.
I get a NullPointerException where ever setBindingContext is called, because panelBinding.getBindingContext() returns null from some reason.
Can someone explain me why this is?
Thanks in advance
Johan SmoldersHi Jan,
First off all thanks for responding.
The bootstrap code is called before the other elements do there method calls to setBindingContext.
So the context of panelBinding shouldn't be empty.
All calls are preformed in the same order as they would be called when you start the JFrame itself.
Now your second remark made me think.
When i instantiate my JFrame in the other projects class does it use the wrong Databinding.cpx?
So the best solution would be: Join all the file's in one project?
Or can i explicitly tell the JFrame which Databindings it should use?
Edit:
As a test i copied my Databindings.cpx file in the project containing the JFrame and named it Databindings2.cpx
I then edited the JFrame class to use this Databindings2.cpx (so i was sure is wasn't using the Databindings.cpx file of the other project)
but the same error accured.
Thx again

NullPointerException when using getMetaData
Hi!
My code :
try {
Class.forName("com.sybase.jdbc2.jdbc.SybDriver");
Connection myConnection = DriverManager.getConnection("jdbc:sybase:Tds:gandalf:4100", "foo", "foo");
PreparedStatement myStatement = myConnection.prepareStatement("SELECT ID, NAME FROM MYSMALLTABLE");
myStatement.executeQuery();
ResultSetMetaData metaData = myStatement.getMetaData();
int nbCols = metaData.getColumnCount();
} catch (Exception e) {
e.printStackTrace();
}My questions are : why does the getMetaData method return null? Are the 4 SQL files in the sp directory usefull for this problem?
I use jConnect5.5 driver, Sybase 11, and jdk1.3
Thanks for help
Simon Pierre NOLINHi,
There are 2 types of MetaData
1) ResultSetMetaData -->
ResultSetMetaData rsmd = <resultset>.getMetaData();
2) DataBaseMetaData -->
DataBaseMetaData dbmd = <connection>.getMetaData();
As u r willing to get the columncount u must use ResultSetMetaData and it is got from
ResultSet not Statement.
Change the code like this:
Connection myConnection = DriverManager.getConnection("jdbc:sybase:Tds:gandalf:4100", "foo", "foo"); PreparedStatement myStatement = myConnection.prepareStatement("SELECT ID, NAME FROM MYSMALLTABLE");
ResultSet rs =myStatement.executeQuery();
ResultSetMetaData metaData = rs.getMetaData();
int nbCols = metaData.getColumnCount();
With Warm Regards

Server: JBoss EAP 6.2.0
Client: JDK 1.7.0_51 x64
JAX-WS: RI 2.2.8 ( via -Djava.endorsed.dirs )
I am getting a java.lang.NullPointerException when calling the operation on the WS endpoint from the client when using non-anonymous replyTo address.
I have simplified the scenario into a small test case that hopefully others can replicate. Since the exception is happening on the client instead of the server, I would think that the container used is irrelevant, but I have specified it nonetheless.

* If there is no namespace specified in the method below, then the CallbackSEI needs to be in the same package as the
* WS endpoint.
@Oneway
@Action(input="http://services.nowhere.org/RandomTest/nextRandomResponse")
@RequestWrapper(localName="nextRandomResponse", targetNamespace="http://services.nowhere.org/")
public void handleNotification(@WebParam(name="return")long random) {
System.out.println("Asynch response received");
System.out.println( random );
//System.out.println("This response relates to the message ID: "+ getMessageID());
In summary:
Server is listening on port 8080
Client will listen in port 8082 for the callback from the server for the SOAP response
Now when I run the client, I see that the proper behaviour as far as ws-addressing is concerned. That is:
client -- SOAP request ( on port 8080 ) --> server
client <-- HTTP 202 ( empty HTTP body ) --- server
client <-- SOAP response ( on port 8082 ) --- server
All well and good, except that I am getting a NullPointerException on the client side when I call the operation.
With debugging of the SOAP request and responses, I get the following output:

As you can see from the output above, the proxy is throwing an Exception when it receives the HTTP 202 response.
Any ideas ?I think I have found when I get this error and probably I have found a bug. I will appreciate if someone can confirm this.
In my BPEL project setup, my BPEL process's wsdl file imports another wsdl from different namespace. Here is sample snippet -
<wsdl:definitions targetNamespace="http://namespace/1">
<wsdl:import namespace="http://namespace/2" location="resources/another.wsdl"/>
<plnk:partnerLinkType....../>
</wsdl:definitions>
Please let me know. I checked the bundled samples with Oracle BPEL PM and did not find any similar case where process wsdl imports another wsdl.
Thank you.
