Which exception is thrown?

Which exception is thrown when a native method breaks?
For example: when a native method cannot access some device.
Is it RunTimeException, or just plain Exception, or perhaps something else?
Thanks.

The native - C - code is yours. If it encounters an
error, it is up to you to decide how to deal with it.No. Im using someone elses native methods.
Chances are, if you are trying to write a wrapper
around someone elses code...Exactly! :)
... you will find the code
throws C++ exceptions. You have to catch them and
deal with them.I know that. That is why I posted a question here. Question is: What is that exception?
One likely way to "deal with them" is to define for
yourself the exceptions you would like to see in
java, and have the native methods construct and throw
those java exceptions. The JNI interface includes
ways of throwing exceptions while in native code.I don't know that. If you could provide some example it would be most appreciated.
Thanks.

Which exception is thrown in overidding method

Hi ,
I have a doubt in doubt in overriding method. What type of exception is thrown in overidding method.

Hi all,
I have a doubt.. I read some where that an overriding
method can throw a different exception from the
orignal one. Does that exception has a restriction
that ..it shouldn't be more Generic than that of the
original?
Yes, this is what the jls in section 8.4.4 has to say about throws and overriding
A method that overrides or hides another method (�8.4.6), including methods that implement abstract methods defined in interfaces,
may not be declared to throw more checked exceptions than the overridden or hidden method.
More precisely, suppose that B is a class or interface, and A is a superclass or
superinterface of B, and a method declaration n in B overrides or hides a
method declaration m in A. If n has a throws clause that mentions any checked
exception types, then m must have a throws clause, and for every checked
exception type listed in the throws clause of n, that same exception class or one
of its superclasses must occur in the throws clause of m; otherwise, a compile-time error occursLets take an example
public class A
   public void meth() throws IOException
        //some code that throws IOException
class B extends A
   //this is ok bcos FNFException inherits from IOException
   public void meth() throws FileNotFoundException
      //code that throws FNFException
   /* THIS WILL FAIL TO COMPILE
   public void meth() throws Exception
      //code that throws FNFException
I think the access modifier in the over riden method
can't be more restrictive than the original one.. For
example..The overriden method can change the access
modifier from default to protected..But not vice
versa..correct.
Cheers,
ram.

Which exception to be thrown when integrity check fails

hey guys just a scenario for ya.
During the developmen of an API for Global Platform,if an integrity check failure occurs reading a value should an exception be thrown, if not then wat procedure should be followed.
put some light on this

dude,the scenario is as mentioned...
an applet calls an api which inturn returns a value.This value is a critical value of th card.So in the memory this value will be stored along with its compliment.
In the api,first of all it has to be checked whether the value and it compliment when 'AND ed' gives zero,this is to ensure that memory is corrupted.So if this check fails in the API what shoukd be done.
Should and exception be thrown or an error status word be return to the terminl

Exception is thrown but exception.getMessage() is null

Hi,
I am wirting a code in which an exception is thrown, I catch this exception in the catch block, but when I display e.getMessage() it displays null.....Can any body help in telling why....
Thanks
Rajnish Verma

getMessage() is just about useless. If you use the no-arg constructor for a Throwable, you'll get a null message. Much, much better for displaying information about Throwables is toString() which will include the class name of the Throwable and the message if it's not null. Out shop never uses getMessage()

Populating OUT parameters when TOO_MANY_ROWS exception is thrown

When I was trying to write code to test out today's PL/SQL challenge quiz, the behavior appears to depend on the table being queried. I can't figure out what attribute of the table drives the behavior (or if there is a different explanation for the behavior).
The quiz is testing what happens when a procedure does a SELECT INTO an OUT parameter and a TOO_MANY_ROWS exception is thrown. The intent is to show that even though the behavior is technically undefined, what actually happens is that the OUT parameter is populated with the first row that is selected (obviously, you would never write code that depends on this behavior-- this is solely an academic exercise). The demonstration code works as expected
CREATE TABLE plch_emp ( emp_name VARCHAR2(100) );
INSERT INTO plch_emp VALUES ('Jones');
INSERT INTO plch_emp VALUES ('Smith');
COMMIT;
CREATE OR REPLACE PROCEDURE plch_get
(out_name OUT plch_emp.emp_name%TYPE) IS
BEGIN
SELECT emp_name
INTO out_name
FROM plch_emp
ORDER BY emp_name;
EXCEPTION
WHEN OTHERS THEN
    dbms_output.put_line('A:' || out_name);
END;
What will be displayed after executing the following block:
DECLARE
l_name plch_emp.emp_name%TYPE;
BEGIN
plch_get(l_name);
dbms_output.put_line('B:' || l_name);
END;
/and outputs
A:Jones
B:JonesWhen I replicate the logic while hitting the EMP table, the PLCH_EMP table, and the newly created EMP2 table, however, I get different behavior for the EMP and EMP2 tables. The procedure that queries PLCH_EMP works as expected but the OUT parameter is NULL when either EMP or EMP2 are created. Any idea what causes the behavior to differ?

create table emp2

Your test was done as a single anonymous PL/SQL block. Which means each proc that was called referenced the same variable/memory - are there perhaps PL/SQL optimisation enabled for the database or session? Or any other settings that could influence the test? Have you tried calling the procedures directly from SQL*Plus using a bind var and not via an anon block and a local var in that block?I have. And the results were the same

As a sanity test - what happens when proc P3 for example is changed to a catersian join/union of emp2 and plch_emp? Do the test results change? Or you can change it as follows:

Of course, you can also put this one down to using an operating system like Windows as a poor database server and not as a magnificent client gaming platform... Well, sure. But you can probably only play World of Warcraft so long before you need to write some PL/SQL.

Detecting when exception was thrown using custom class loader

Hello all,
I would like to implement the solution described here - http://stackoverflow.com/questions/75218/how-can-i-detect-when-an-exceptions-been-thrown-globally-in-java - that uses custom class loader in order to detect when an Exeption thrown somewhere in the JVM hosting my app, please note that exceptions might be thrown from 3rd party jars the app is using. So, thanks to help I got from another post, I've managed to code the custom class loader. My question is how can the class loader wrap the original exception, as the methods in ClassLoader deals with classes, not instances. So where should I set the original exception?
Thanks!

I think I'm missing something fundumental, forgive me for being slow...
This is what I did so far. For the exception wrapper I made a simple class extens Exception that recieve Exception in its ctor and store it. I also subclassed ClassLoader and override its loadClass(). I've registered it as the system classloader. My thinking was to check in that point that if the requested class is instance of Exception and if yes, returning my wrapper class wrapping this exception. But, since loadClass() return class, how can I set in the wrapper the original exception?
In addition, let's say 2 different places in the code throws NPE, to my understanding the classloader will load NPE only once, so how throwing the NPE in the second time can be detected?you are missing a key point. you should creating a custom implementation of the NPE class which hooks into your detection code in its constructor. from that point forward, anytime any NPE (which is your custom class) is constructed, you can detect it.

Check if an exception is thrown during my JUnit test

Hi all,
I've been writing unit tests for the application I'm writing.
I'm trying to write one very generic test which will simply open up the application, press some buttons, and close it back down, and confirm that no exceptions were thrown at any time during the test.
Unfortunately, while I figured I could just wrap the whole thing in a try/catch block, it seems that I have an exception that is being thown in the AWT-EventQueue which isn't being caught. The test passes fine, but I want it to fail.
What is the best way to go about checking for this? Should I be running the test in the event queue? Or should I have my own error handler to catch the exceptions?
Thanks!

Exceptions are returned up the call stack within the thread of execution.
You have two threads. The one that the test runs in A, and another B.
You can't catch or even see an exception in A that originated in B as an exception (you can't catch it.)
So you need to find some other way, some other place, to put a catch, in thread B and then create data which indicates whether it worked or not. Or find some other existing data that changes state because of that.Well, the question that I asked in my original post was exactly that: how do I find out about an exception that is thrown in another thread? If something got stated incorrectly, maybe it was in the later posts?
It can't be impossible: I can think of one very simple solution to my question, but it isn't very good. I can simply replace the Standard Error writer with one that sets a"fail" flag every time it is called. Then my test can fail every time Standard Error is written to, no matter which thread it's in. Obviously, this isn't a great solution, because, while it would fail the test every time an exception was printed, it would fail other times as well.
So with a bit more work I could parse what's written to stderr myself, to check if it's a real exception. But this really seems like re-inventing the wheel. Is there no standard pattern for creating a test that confirms that you can run something without generating exceptions?

Exception of type 'System.OutOfMemory Exception' was thrown while running

We have a web application develeoped in ASP.Net, SQL Server 2005 , Crystal Reports 10.2. When I try to run a report which has around 5 lakh records (the query to fetch the records in sql server takes around 1.5 to 2 minutes) gives an error Exception of type 'System.OutOfMemory Exception' was thrown.
Can anybody help !!

Hello, Balla;
the first thing to check is that the ASP.NET Worker process has rights to your Temp folder. You will find where it is by checking your Environment variables.
Use the correct name for the ASP.NET worker process depending on your operating system - LocalMachine\IIS_WPG(Windows 2003 Server) or ASPNET(XP) or (Vista) IIS_IUSRS
To give the IIS_WPG account full control of a folder:
1. Right-click the folder and select 'Properties'.
2. Go to the 'Security' tab and click the 'Add' button.
3. Click the 'Locations' button and select the
computer name. Click 'OK'.
4. Type "IIS_WPG" under the 'Enter the object names to
select' box.
5. Click 'Check Names'. <Your machine name>\IIS_WPG
appears. Click 'OK'.
6. Check 'Full Control' from 'Permissions for IIS_WPG'.
Click 'OK'.
====================
NOTE:
The IIS_WPG includes the LocalService,
System, and NetworkService accounts.
====================
If that is not the issue:
What database driver are you using in the design of your report? Go to Database|Set datasource location and tell me the properties of the database connection.
Do you logon to the database in your code or pass the data to it using Datasets?
Are there subreports in the design? How many are there? What section are they in? What data source does each one use?
Do you have a lot of formulas in the report?

Memory leak when exceptions are thrown?

Hello,
I'm doing a simple database connect with the JDBC Oracle 8.1.6 oci8 drivers on Solaris. It seems whenever I try to repeatedly connect to a database, and an exception is thrown, such as database not found, or wrong password, the program size grows and grows until it runs out of memory. I've narrowed it down to being the getConnection operation as the casue of this memory leak.
Now, if I repeatedly connect successfully, there is no problem, it will run all day, but if there are exceptions thrown, memory leaks. Has anyone else encountered this?
I'll paste a sample program below which shows the problem. Maybe someone can help???
import java.sql.*;
import java.util.*;
import java.io.*;
public class connect extends Thread {
private oracle.jdbc.driver.OracleDriver oDriver = new oracle.jdbc.driver.OracleDriver();
private Connection connection;
* Open a connection to the database
private void connectToDB() {
try {
connection = DriverManager.getConnection ("jdbc:oracle:oci8:@test", "test", "test");
connection.close();
} catch (SQLException e) {
e.printStackTrace();
System.out.println("couldn't connect");
public void run() {
try {
DriverManager.registerDriver(oDriver);
} catch (SQLException e) {}
while(true) {
try {
sleep(1000);
connectToDB();
} catch (InterruptedException ie) {}
public static void main(String[] args) {
connect conn = new connect();
conn.start();
null

Try this:
private void connectToDB() {
try {
connection = DriverManager.getConnection ("jdbc:oracle:oci8:@test", "test", "test");
} catch (SQLException e) {
e.printStackTrace();
System.out.println("couldn't connect");
finally {
connection.close();
null

NO EXCEPTION IS THROWN FROM THE PERSIST

We are using Glassfish and MySQL. When we do a persist with a bad object/query, internal DB errors are NOT being reported back to the caller in any way, but Glassfish knows that the error occurred. Here is a schematic of the situation:
     Glassfish starts a CMP transaction and calls our bean
          Inside the bean we have code like this:
               obj = (a new object that will cause a DB error when persisted)
               try {
                    entityManager.persist(obj)
               } catch (Throwable t) {
                    report to the user that the throwable happened
          bean returns
     Glassfish manages CMP transaction
What we see is the following:
     - The persist has an internal failure and generates error messages in the Glassfish system.log file.
     - NO EXCEPTION IS THROWN FROM THE PERSIST, so the application code thinks that the persist completed correctly
     - At the end of the bean operation, Glassfish (correctly) rolls back the transaction.
At the user level the result is that the request succeeds but nothing is put into the Database!
We are not asking about the cause of the DB error. From reading the system log we know what happened and can fix it. Our problem is that problems in our field-deployed systems cannot be detected by the application code so failures cannot be reported to the user.
The critical question is:
     Is there a way for the application code in the bean to see that an error occurred?
By the way, we also have a secondary question: Why is the erroneous persist tried 6 times before deciding it won't work? Is there an option somewhere that says to try 6 times?
The Exception as reported in the system log (only one copy of it) is included below.

This is because the persistent context is not synchronized with the database until the commit is being executed.
You might 'force' this by calling entityManager.flush() right after the call to persist(...).
Or you register a transaction synchronizer and check the transaction status on afeterCompletion().

How to fail messsages when timeout exception is thrown in BPM?

Hi
In my BPM, if the time out exception is thrown in BPM, in SXMB_MONI, all the inbound messages' staus is 'processed sucessfully' ? How can I make the message fail? With a red flag or anything indicating exception?
In my design I used deadline branch to throw time out exception.And in the exception branch I used control step to cancel the process.

Hi,
In my design I used deadline branch to throw time out exception.And in the exception branch I used control step to cancel the process
If this is what you have designed then increasing the timeout using the above mentioned blogs doesn't seem to be logical:) (BPM will throw the error when the deadline is meet....can't understand how by increasing timeout will help you)....instead of increasing the timeout you can increase the time limit mentioned in the deadline branch itself to ensure that your message will be processed in that particular time limit.
Since you have reached the timeout it means that desired message processing has failed so better you raise an alert instead of going for a increase in timeout....increasing timeout decreases performance...

Abhishek.

Exception is thrown "mydb is not bound"(needs urgent help)

We r three students and our final project is a BPM(Business peocess Management)system.
BPM is actually a workflow system(managing the business processes)and all the rules and constraints are applied from the Rule Management System.
we have started the implementation, and therefore we need some help related to the implementation.
We r using EJB2.0 with JBuilder9, JBoss3.2 as the application server and tomcate as the web server.
problem:
I want to create manual database connection using DataSource,
I am using mysql and database name is mydb.
I have done all the reqiured configration of mysql with Joss and it is working.
After getting the initial context, when i try to lookup the datasource, exception is thrown "mydb is not bound"
Initial context is correct because i have tried entity beans asd it works well.
code is
Hashtable contextValues = new Hashtable();
contextValues.put(Context.PROVIDER_URL, "jnp://loopback:1099");
contextValues.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
Context context = new InitialContext(contextValues);
context.lookup("java://mydb");
Kindly help me if u find time,
regards!

try java:comp/env/jdbc/mydb or java:comp/env/mydb

Exception is thrown or not

What should I do to ensure that a certian part of my code is always excuted whether an exception is thrown or not?

Put it in a finally section and the code that might throw in the preceding try block.
Chuck

Which exception is thrown?
