How to hook(Listen) to java's exception handler?

Hello Guys,
If you know you can replace or add new EventQueue in AWT event queue listener, so what ever events occurs, will be received by own extended class of EventQueue.
Now how to listen to the global exception listener,
Like,
I want to monitor for a perticular execution of a program , which says how many exceptions are raised by Java, and which are the exceptions.
So is there any method where i can listen using some interface for exceptions...???

Nachiket

Hello,
I tried to find out somethings on java.beans.ExceptionListener, but i am unable to find out any help or anything which explains how to use it.

JAVA BEANSHELL EXCEPTION HANDLING

Hi
still new to ODI
I have created a java beanshell script in ODI which calls a simple java class, cars, then sets the no of seats to a value designed to raise an exception. Exception raised but procedure works OK,
How can I register the fact that it has failed through exception handling? (It is possible that my java exception handling isn't quite right)
The no of seats has no effect on the success/failure of the ODI procedure, but the log shows that the exception is caught !
any assistance gratefully received.
Regards
Terry
cars class: (added to agent start)
====================
public class cars {
private int seats;
public void setSeats (int seats) throws tooManySeatsException {
if (seats) < 100) {
this .seats = seats;
} else {
throw new tooManySeatsException("Too many seats");
public int getSeats () {
return this.seats;
class tooManySeatsException extends Exception {
public tooManySeatsException (String msg){
super();
Java beanshell procedure in ODI
====================
import cars;
public class carsTest {
public carsTest(){
public void init(){
cars c = new cars();
c.setSeats(20);
//c.setseats(200);
try {
carsTest ct = new carsTest();
ct.init();
} catch (Exception e) {
throw Error (e);
}

Your code throws exception when you set value >100 but you are setting 20 thus it would not throw exception.
In the procedure step you can uncheck "Ignore error" flag to let execution failed on throwing any exception from your code. If you check that flag then the execution would not fail rather lease the task in warning state.

How to retrieve error information from an exception handler?

I have an Embedded PL/SQL block in a Pro*C
application that uses something like the following to catch exceptions and fill a host variable with diagnostic information.
It then re-raises the exception so that
the global error handler specified with a
WHENEVER SQLERROR DO ... can log the error and determine the appropriate action.
EXCEPTION
WHEN OTHERS THEN
:zerrtext := 'Failure occurred at ' | | mylocator;
RAISE;
According to all the Oracle docs this should work; but it does not. Re-Raising the exception within PL/SQL appears to negate the assignment of the string data to the host variable. When the global error handler runs, the host variable is empty.
The assignment works if the 'RAISE' is commenting out; but then the detailed Oracle exception data is lost, and the global error handler never gets an opportunity to run.
Does anyone know why re-raising the exception voids the assignment within the PL/SQL exception handler; and how to prevent this from happening?

Have you tried getting the value from 'sqlerrm'? In PL/SQL this is a built-in placeholder for the ORA-xxxx code and message when trapping exceptions.
Hope this helps,

Java Junit4 Exception Handling

Hi,
Is it possible to test an excption in JUnit4 with out,
throwing an exception object from the oriogional class.
How can the exceptions which usualy throw errow objects
can be handled in JUnit4.
thak you

Thank you for the reply, but I was expecting a way test
exceptionWhat is a 'way test exception'?
such as "FileNotFoundException"Why is 'FileNotFoundException' a 'way test exception'?
original code if an object of "FileNotFoundException" is not
thrown then, Junit is unable to detect the exception.Well of course because there isn't one. Is there a reason why you can't use the suggestion above?
>
In my origional code I cannot throw an exception objectSo why do you need to test it?
so JUnit does't see "FileNotFoundException" etc.. as an ExceptionBecause you haven't thrown it,
I need to find a techniques to test such cases
What cases? You haven't made any sense at all here.

Generic Exception Handler/Listener

All,
I have a web application and I want to create a generic exception handler/listener which will listen to all the exception(checked and runtime) which are thrown by web application.
Any idea how can I do this?
Regards.

Hi,
I want to build a generic exception handler which can be reused in any java j2ee applications. Unlikely. Probably impossible.
I have java application which is communicating with other 3rd party applications like webservices, webmethods , etc from where we are getting an errorcode which will be used in our java application to do a lookup to get the respestive error message from the resource bundle. Please clarify in such case how I can go with a generic exception handler which will be build separately and will be integrated with Java applications to handle the exceptions and errors.An excellent example of why a universal exception handler wouldn't work.
At some point a call tree looks like A->B->C, where C (or beyond) that is where your communications problem occurs. The impact of that depends on the application.
For example if a user types in a url (at A) and the server (C) fails to resolve it then that is a user problem.
However if nightly batch process expects to download an update file every night from one location and it can't connect then that is an operations error (or notification/alert.)

Exception handling in Web Services

Hi all,
I am exposing ejb2-based webservices and am unable to find a way to throw checked Exceptions.
Could anyone provide resources about how to leverage SOAP/WSDL features of exception handling (i.e. wsdl:fault tag)?
Thanks, regards
Vincenzo

Hi, thanks for replying
actually on saphelp I found that supported Exceptions are:
java.lang.Exception -> no fault generated
java.rmi.RemoteException -> deploy refused with explicit error (RemoteException not allowed in ejb business method signature)
java.lang.Throwable -> doesn't seem very appropriate to use such a root class
Any suggestion?
Thanks, regards

Very poor implementation.
a) Absolutely no need for that exception handler in there. It should be removed.
b) As it's a procedure for logging exceptions relating to UTL_FILE, it would seem error prone to be logging the errors with UTL_FILE. For example, what is it supposed to do if the exception is raised because of lack of disk space in those file locations? How is it going to write out the exception with the disk full? Also, if the exception handler is used by multiple processes, then only 1 process at a time can access the log file to write it's exceptions, so it doesn't scale well. Better logging is done by having an autonomous transaction procedure that writes log/trace messages to dedicated table(s). That also means that the logs etc. can be viewed, as appropriate, from any client using SQL (either manually or through a application written to view logs etc.), rather than requiring physical/remote access to the server o/s to go and view the contents of the file, which in itself could lock the file and prevent any process from writing further logs whilst it's being used.

How to prevent java.io.exception when someone enters a bogus page in theURL

Say i have a page called Test.jsp. The user goes to it and everything is fine. If the user happens to play with the url and changes it to Tes.jsp, i get java.io.exception. Is there anyway to catch this?

Most JSP servers have a configuration option to serve
up an error page in situations like this. Yours
probably does too.Once you find that, make it your error page with a page directive of isErrorPage="true". Then you have access to the implicit exception variable name to determine if it is really a 404 exception.

EM 10g : java.lang.Exception: Exception in sending Request :: null

I have installed 2 db on 10.2.0.1.0. The first one is running fine and easily manageable via Enterprise Manager. When I open EM on the second db I receive "java.lang.Exception: Exception in sending Request :: null" with no further explanation. When I try startup/shutdown, I get "Couldnot contact the agent. Verify that the url for the agent is null". However the db service and the DB console are up and running. I can connect via SQL*plus to manage my DB.

Generic Exception handler in java

We have developed a client java application with our own exception hierarchy derived from java.lang.exception. We raise our own exception in case of error scenarios. But there is one additional thing which we want to do:
1. When ever any exception is raised in our exception we want to do some generic exception handling (like kicking of some module which collects the log files and send it to the administrator.
2. We want the above activity to happen also when any runtime exception is raised. We are not catching any runtime exception and we have no handle for this.
How should we go about this. Can we write a very low-level generic exception handler?
We do not want to have done at every catch block we have in our code. I mean we want to have some hook at a very generic place.
Let me know if some body can be help me on this.

As far as I know, for exceptions that are caught, you must make a call to a generic handler in the catch block, or you may rethrow the exception as a RuntimeException, and let it propagate.
For RuntimeExceptions and Errors in threads that you create, the easiest way to solve this is to subclass ThreadGroup, override uncaughtException with the appropriate code, and create all your threads in this group. For a thread like main, have the first thing in the thread be the creation of a new thread in the new group, then pass control to that thread. For fixed threads, like the event queue, someone had a suggestion already. Note that uncaughtException is only called just before the thread ends, so an exception that shouldn't end the thread should be handled seperately.

How do i run a java program an another directory?

How do I run a java program that's in a different directory?
I have been doing this in the command line:
java "C:\Document and Settings\freeOn\Desktop\Java\Test\test"
and I get
Exception in thread "main" java.lang.NoClassDefFoundError:
C:\Document and Settings\freeOn\Desktop\Java\Test\test
I just thought there might be a quick way to do this and not
have to cd to the following dir evertime i want to run an app in
console.
The test.java file is this:
import java.io.*;
public class test {
public static void main(String args[]) {
System.out.println("Testing.....");

Ok I looked in the java help and found the classpath, this makes it alittle easier.
java -cp C:\DOCUME~1\freeOn\Desktop\Java\Test\ test
At least i can run this in the run dialog which makes it easier thanks for you help kota balaji

Keytool error: java.lang.Exception: Keystore file does not exist:

Hi All,
While listing the keystore using the command keytool -list, I got the error message that
keytool error: java.lang.Exception: Keystore file does not exist: C:\Documents and Settings\subramanian.arivalag\.keystore
I noticed there is no file .keystore in the above mentioned directory. What's this .keystore file? Will it be created automatically or should we create manually?
Already I created a keystore using -genkey command and received CA authority also.
Kindly provide me more details about .keystore file and how to handle this error.

If you specified a keystore filename when you created the keystore
i.e. keytool -genkey -alias jboss-ssl -keyalg RSA -keystore my_name.keystore -validity 3650
then you need to specify the same keystore when you export the cert
i.e. keytool -export -alias jboss-ssl -keystore my_name.keystore file my_name.cer

Java.lang.Exception: Could not get name for DC project

Hello Experts,
We have a code which is downloaded from SVN repository.
I have imported the code from my desktop into NWDS and when I try to deploy it throws,
java.lang.Exception: Could not get name for DC project
I have referred few threads in SCN and solution suggested is to change the workspace and create a new DC & copy the _comp from old DC.
I tried the above solution but there are lot of build errors as we have few RFC models and it is throwing build errors for missing model reference.
Kindly help me on how to fix the error.
Thanks, Swarnaprakash

Dear Swarnaprakash,
The Web Dynpro DCs Import C:\----\user\.dtc\LocalDevelopment\DCs\sap.com\test and
the related package for DC is missing once check it after try to import.
Depending on which Java compiler preferences are set, you may see some
warnings in the "Task" view after importing the project. If the severity level for problems of type "Unused imports" (set in Preferences – Java – Compiler) has the value "Warning", the compiler will issue a warning for unused import references. Ignore these warnings!
Still You getting means delete your .metadata before take the backup.after open the NWDS again it will set new configurations in your system.
Thanks & Regards,
Durga Rao.
