Can we override Exception Class in Java ?
I have done a project in structs 1.2 .
I have used String variable without checking for null.
so I get a null pointer exception.
String str = null;
str.equals("jayaraj"); //exception raised
can i make a customized null pointer exception ?
1) yes. NullPointerException isn't final, bizarrely
2) why didn't you just try it?
3) why the h3ll would you want to? is this a special kind of null or something??
4) this isn't overriding. it's extending

Custom DSC can't find exception class, error about export-packages
I've got a DSC which has a method that can throw two custom exceptions. It all works, and the exceptions show up available for handling in a process in Workbench, but the issue here is that the server.log has this error:
2013-05-13 16:59:35,353 WARN [com.adobe.workflow.AWS] An exception has been thrown for which the class information has not been exported in the service's export-packages, it is essential for the clients of the service to have the class information via export-packages to handle the exception.
Yet I have added the exceptions' package to the export packages. And I also made a DataTypes entry for each of the two exceptions as well.
Does anyone have an idea how I can get rid of this warning?
Thanks,
JackYou continue to use slash instead of dot.
You did not follow any of my suggestions and still awarded me dukes,
so I feel I have to make a last attempt.

How to make a Exception class in java ?
I want to make a class called SomeException. I want to throw this exception from my class Myclass. How to do it ??
Just let SomeException extend Exception (or RuntimeException) and throw it the same way you'd throw any other exception. There's no magic involved.
-
Is there anyway I can hook the exception class to catch any and all exceptions or basically what I am trying to do is have an error reporter class and right now I have try catch blocks in every one of my methods that then from that sends the error to the reporter class and then the reporter sends the messages to my server. Is there a better way of doing this for example some how hooking or extending the exception class?
Any other ways? I just want to see all the ways and
select the best and easiest to implement.No. There isn't any other way to setup a global error handler.

How can i execute Spaces API in java main class?
Hi
I am able to execute Spaces API through portal application. However if i try to execute it in java main class, its throwing an exception
"SEVERE: java.io.FileNotFoundException: .\config\jps-config.xml (The system cannot find the path specified)"
oracle.wsm.common.sdk.WSMException: WSM-00145 : Keystore location or path can not be null or empty; it must be configured through JPS configuration or policy configuration override.
How can i set this path, so that i can execute Spaces API from java main class.
Need this main class to configure in cron job, to schedule a task.
Regards
RajHi Daniel
Currently i have implemented create functionality in my portal application using Spaces API, which is working fine. Now the requirement is, i need to implement a "Cron Job" to schedule a task, which will execute to create space(for example once in a week). Cron job will execute only the main method. So I have created java main class, in which I have used Spaces API to perform create space operation. Then it was giving exception.
Later I understood the reason, as I am executing the Space API with a simple JSE client, its failing since a simple java program has no idea of default-keystore.jks, jps-config.xml, Security Policy. Hence i have included those details in main class. Now I am getting new error,
SEVERE: WSM-06303 The method "registerListener" was not called with required permission "oracle.wsm.policyaccess"
For your reference i have attached the code below, please help. How can i use Spaces API in java main method(i mean public static void main(String[] args) by giving all required information.
public static void main(String[] args) throws InstantiationException,

SpacesException {

How can I compile and run other java classes from within an application?
Hello there everyone! I really hope that someone can help me. I am writing a program that must be able to compile and run other java classes that are in different files, much like development environments like Kawa or Forte allow you to do.
There has to be a way of doing this ( I hope!! ), but i can't seem to find it!!
I have tried using this command to compile:
Runtime.getRuntime().exec ("c:\\programs\\javac className.java");
...and this one to run:
Runtime.getRuntime().exec ("c:\\programs\\java className");
...but neither works!!! I can compile and run classes that are in the same file as my application, but I can't get it to work at all for files in different directories or files.
PLEASE, PLEASE, PLEASE help me - i've run out of ideas, and i need this to be working in 3 days!!!
Thank you very much for any help anyone can give me, I really appreciate it!! Thanks again!!
Adrian ( ...in distress!! )public class JavaCompiler{

}This should get you going. You may consider looking into the System.getProperty() method in order to determine the type of OS it is running on in order to findo out what command to run. I know that the sun tool listed above is nice, but by my understanding the sun tools provided are not guaranteed to stay the same. I'm no expert on this matter, but that is one of the reasons there is no API documentation for those tools. Also, I don't believe those tools come packaged with the JRE. (Of course if you are making an IDE it will be expected that the user has an sdk installed. Good luck with figuring this thing out. -
New problem -- My java code can't see my CLASSES from Mapping Workbench
Donald and others -
I am VERY new to TopLink......
I was at the last Oracle Developer Days in Northern Virginia. Donald convinced me and my co-workers to use TopLink for our upcoming project. I have been having tons of problems getting it to work correctly. Maybe I need a TOPLINK license plate, like Donald!!!
Here is my newest problem. I can create a DatabaseSession, login to it, write a query and log out of it.
However, I can only do this if I remove my classes from the Mapping Workbench. As soon as I add even one class to the Mapping Workbench......I get an error as follows:
LOCAL EXCEPTION STACK:
EXCEPTION [TOPLINK-3007] (TopLink - 9.0.3 (Build 423)): oracle.toplink.exceptions.ConversionException
EXCEPTION DESCRIPTION: The object [mil.usa.lbit.isr.TestIsr], of class [class java.lang.String], could not be converted to [class java.lang.Class]. Please ensure that the class [class java.lang.Class] is on the CLASSPATH. You may need to use alternate API passing in the appropriate class loader as required, or setting it on the default ConversionManager
INTERNAL EXCEPTION: java.lang.ClassNotFoundException: mil.usa.lbit.isr.TestIsr
Can anyone tell me where I need to put my class files so the java code can see them via the ISR.xml deployment file.
I currently have these files in a .jar file on the system path and in my web-inf folder and in my project settings. I put them everywhere I could think of, but no luck.
Here is my code:
package mil.usa.lbit.isr;
import mil.usa.lbit.LbitColors;

import java.math.*;

public class TestIsr extends ISR {
public DatabaseSession session;

public TestIsr() {
this.name = "TestISR";
this.color = LbitColors.AMBER;
this.metric = 97.00;
public boolean isConnected() {
if (session == null)
System.out.println("Not Connected");
return false;
System.out.println("Connected");
return session.isConnected();

session = project.createDatabaseSession();
session.login();
System.out.println("Logged in");
public void runQuery() {
ExpressionBuilder builder = new ExpressionBuilder();
Expression expression = builder.get("isr_id").equal(3);
System.out.println(expression);
//TestIsr isr = (TestIsr) session.readObject(TestIsr.class, expression);
//System.out.println(isr);
public void logoutOfDatabase() {
session.logout();
System.out.println("Logged out");
public static void main(String[] args) {
TestIsr testing = new TestIsr();
testing.isConnected();
testing.loginToDatabase();
testing.isConnected();
testing.runQuery();
testing.logoutOfDatabase();
Thanks in advance.
Donald please email me and maybe we can chat on the phone if you want to offer some help.
AndyThanks for the reply!
However, I did try to implement that yesterday.
When I add the "getClass().getClassLoader()" to the "XMLProjectReader.read" call, the codes loses site of my project (.xml) file.
Here is the new line:
project = XMLProjectReader.read("C:\\LBIT TopLink\\ISR\\ISR.xml", getClass().getClassLoader());
Here is the new error:
EXCEPTION [TOPLINK-7099] (TopLink - 9.0.3 (Build 423)): oracle.toplink.exceptions.ValidationException
EXCEPTION DESCRIPTION: Could not find xml project file which is specified in properties file: xmlProjectFile=C:\LBIT TopLink\ISR\ISR.xml.
oracle.toplink.exceptions.ValidationException oracle.toplink.exceptions.ValidationException.projectXMLNotFound(java.lang.String, java.lang.Exception)
oracle.toplink.sessions.Project oracle.toplink.tools.workbench.XMLProjectReader.read(java.lang.String, java.lang.ClassLoader)
But my code could find that file before I added the "getClass().getClassLoader()" code.
Maybe I can avoid this problem by "deploying the XML file in my application jar?" Could you please explain more about this option after answering the first part of my question.
Any other posters feel free to help me too.
I know TopLink is a powerful tool, I just keep hitting these hurdles. ARRRRRRRGGGG!!!
Thanks again,

How can my custom DCErrorHandler class throw/handle an exception?
I had written a custom DCErrorHandler extending the DCErrorhandlerImpl as similar as shown in SRDemo example.
Assume that i have a method authenticateUser() in AppmoduleService Class calling from Backing Bean.java where in i encountered ArrayOutOfBoundsException. So how can i catch this exception without using try catch block? if i use
try{
authenticateUser();
catch(Exception eX)
{} the exception is well-handled.Then what exactly my customErrorHandler class doing?
Do the above customErrorHandler class help in this case by replacing try-catch?From where my customErrorHandler's methods are invoked.
If i want to do it exlicitly from any method of my backing bean class can i do it?
LoginBackingBean.java
public String loginButton_Action()
ArrayList userDetailsList = null;
LoginService service = (LoginService)ADFUtils.getLoginServiceInterface();
if(service != null)
userDetailsList = service.checkUserLoginDetails(getUsername(), getPassword());
if(userDetailsList != null && userDetailsList.size()>0) {
JSFUtils.storeOnSession("key_loggedUserDetails",userDetailsList);
return "success";
else
JSFUtils.addFacesErrorMessage("You have entered an invalid User name and/or Password.");
return "wrongLogin";
else{
return "wrongLogin";
Now assume that i have customDCErrorHandler class and also assume that an exception will be thrown ..say ArrayOutOfBoundException.
if i keep the above code in try and catch block the user login screen is remained as it is by catching the exception.
if i remove the try and catch block user screen if filled up with so many debugging messages as shown : "500 Internal Server Error
javax.faces.FacesException: #{login.loginButton_Action}: javax.faces.el.EvaluationException: java.lang.IndexOutOfBoundsException: Index: 1, Size: 0 at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:98) at oracle.adf.view.faces.component.UIXCommand.broadcast(UIXCommand.java:211) at javax.faces.component.UIViewRoot.broadcastEvents(UIViewRoot.java:287) at javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:401) at com.sun.faces.lifecycle.InvokeApplicationPhase.execute(InvokeApplicationPhase.java:95) at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:245) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:110) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:213)
So can we avoid this by using my customDCErrorHandler ???? If so i need a sample code.
More over if i use a customDCErrorHandler class,
Do i need to bother about the exceptions occuring in the application? -
How can i display the result of java class in InputText ?
Hi all,
How can i get the result of java class to InputText Or OutputText ???
also can every one in the forum give me road map for dealing with java in oracle adf because i'm beginner in oracle adf
i saw some samples in oracle adf corner but it's difficult for me.User,
Always mention your JDev version, technologies used and clear usecase description (read through this announcement : https://forums.oracle.com/forums/ann.jspa?annID=56)
How can i get the result of java class to InputText Or OutputText ???Can you elaborate on your requirement? Do you mean the return value of a method in a class as output text? Or an attribute in your class (bean?) as text field?

Thanks for the quick reply.
I have gone through the notes 1535201 & now on 1606563 after your advise.
Both the notes says the fix is available on 7.01 after SP 07 and we are on SP 14 already.
Also just in case I did checked with our basis and they confirmed we are a head and we have the above notes in our release already.
Unfortunately the notes are not the solution to the investigation till date.
Thanks,

Can I call my own custom java class from JavaScript?
You can instantiate a "JavObject" from client-side JavaScript:
http://developer.netscape.com/docs/manuals/js/client/jsref/javobj.htm#1193137
What I don't know is, does JavaObject mean only the browser's JRE classes? Can I instantiate a class I wrote?Also, does this even work in IE anymore? I'm trying it and it doesn't seem to work! Anyone know if this feature was removed? I have the latest Java plug-in.

Can we extend the Throwable class instead of Exception Class??
Hi all..
Can we extend the Throwable class instead of Exception Class while creating our own custom Exception?If not Why?
Please give your valuble advices..
Ramesh.I don't want to hijack the thread here, but in a conversational tone...on a related note.. I've thought about this too a bit and wondered if there are some recommended practices about catching and handling Throwable in certain applications. Like the other day I was debugging a web application that was triggering a 500. The only way I could find the problem in an error stack was to write code to catch Throwable, log the stack, and then re-throw it. I considered it "debug" code, and once I solved the problem I took the code out because, my understanding is, we don't want to be handling runtime problems... or do we? Should I have a catch clause for Throwable in my servlet and then pass the message to ServletException?
So along with the OP question, are there separate defined occasions when we should or should not handle Throwable? Or does it just all depend on circumstance? -
Where can I find the original code for class in Java API
I am learning Java programming and wanted to see how professionals handel all cases. Can anyone tell me where I can find the original implementation code for classes in Java API? It would be a great help for me.
the basic source is where you installed java in a file called java.src, its either in the main dir of one of the sub dirs ( mmm ), contains all the source code for all the classes in the api.
