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?

Check Conditions and exceptions

I have the two tables:
The first is a Chequing accounts table. This table has two
number fields, the first is called balance, and the second is
called Overdraft.
The second is a Savings accounts table. This table has one
field of importance, and that is the balance alone.
I was thinking of making triggers that would fire after the
transactions are executed. If the trigger finds that the either
the Chequing balance is lesser than the negative overdraft, or
if the Savings balance is lesser than 0, then the trigger would
prevent the changes from being made.
I was considering the use of a trigger that would spread an
exception to the Transaction procedure. This would work as
follows (Pardon me if the code has problems, I'm just writing
from scratch):
create trigger chq_acct after update on chq_acct for each row
declare
declare exception insufficient_funds here
begin
if balance < (- overdraft) then
raise insuffiecient_funds
end
The things I need to know is how to pass this exception onto the
procedure that is handling the update. However, I have not seen
examples on how this is done yet.
Another possibility is more modest and probably easier to
handle: using a check constraint to verify data. In the savings
acct, I can simply add a check constraint and if it is violated
during update, catch the exception with the appropriate code
(which I don't know what it is). However, I do not know about
the check constraint for the Chequing accounts. It should be
Balance > (- Overdraft), but this is a "variable" constraint as
different customers have different levels of overdraft. Does
Oracle handle this kind of constraint? If not, how should one
handle it?
Thanks

hi....
Trigger is a good idea.
You can raise an application error in the trigger. Carefully
define the two constants, ...msg and ...num - especially since
the num should not be used for other exceptions. I usually put
them in the specification of an PL/SQL block for global access.
I added them to your code an example of what's needed.
create trigger chq_acct after update on chq_acct for each row
declare
kc_sqlerrmsg_insufficientfunds CONSTANT VARCHAR2
() := 'Insufficient funds.' ;
kn_sqlerrmum_insufficientfunds CONSTANT NUMBER(5,0) := -
20000 ; -- between -20000 and -20999
begin
if balance < (- overdraft) then
--raise insuffiecient_funds
     RAISE_APPLICATION_ERROR ( kn_sqlerrmum_insufficientfunds
kc_sqlerrmsg_insufficientfunds
end Then when ever an update throws the exception, the query will be
rolled back UNLESS you handle your new exception.
Put your update query into an PL/SQL block with the exception.
Be sure to tie the exception in the trigger using your defined
exception and the all important ...num.
The WHEN OTHERS THEN RAISE allows other exceptions to be handled
by other, containg PL/SQL blocks.
In the EXCEPTION part of the PL/SQL block, when the
insuficient_funds exception is thrown, the variable SQLCODE will
have your ...num in it and SQLERRM will have your ...msg in it.
This is cool because when another UPDATE not in a block throws
the exception in the trigger, whoever is trying to figure out
what happened can use these!
DECLARE
kn_sqlerrmum_insufficientfunds CONSTANT NUMBER(5,0) := -
20000 ; -- between -20000 and -20999
     insufficient_funds     EXCEPTION ;
     PRAGMA EXCEPTION_INIT ( insufficient_funds,
kn_sqlerrmum_insufficientfunds )
BEGIN
     UPDATE .... SET balance .... ;
EXCEPTION
     WHEN insufficient_funds THEN
      ...code to handle the potential overdraft...
     WHEN OTHERS THEN RAISE ;
END ;
Hope this helps. Good Luck.

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().

Sun J2EE SDK 1.3_01, java.lang.ClassCastException thrown during deployment

I encountered a bug while using the deploytool to deploy
an EAR file to the Sun J2EE 1.3_01 server.
I submitted a bug report to Sun via the Sun Java Developer Connection.
(Sorry, it has not been assigned a BugID yet)
Question:
Does anybody know if the web container in Sun's
J2EE 1.3_01 server supports access to local enterprise beans?
Screenshots of the bug are available at
http://sync4j.sourceforge.net/deploymentbug/
Full details below....

C:\j2sdkee1.3\bin>j2ee -version
Java 2 Enterprise Edition version 1.3_01, build 1.3_01-b01
I built a EJB 2.0 compliant stateful session bean.
The session bean has a remote interface (ISyncRemote),
a remote home interface (ISyncHomeRemote),
a local interface (ISyncLocal),
and a local home interface (ISyncHomeLocal).
I built an HTTP Servlet that is supposed to access
the Stateful Session Bean using ISyncHomeLocal and
ISyncLocal
I run "deploytool.bat" in GUI mode to perform the deployment.
During deployment, the deploytool GUI displays a message
box which states:
"There was a deployment error.
java.rmi.ServerException: RemoteException occurred in server thread;
nested exception is:
java.rmi.RemoteException: An error was encountered while loading
a web component.
Please refer to

The "error.log" file did not contain any useful information.
I ran the J2EE "verifier.bat" tool to verify that my EAR archive is OK.
The Sun J2EE server output this error string:

Does the Sun J2EE server implementation support the invocation
of Session EJB's via a Local interface?
Does the Sun J2EE server implementation allow a Servlet to invoke
Session EJB's via the bean's Local interface?
While researching this issue, I read the J2EE 1.3 final specification.
The spec says:
"The EJB container is required to access to local enterprise beans.
We recommend that the web container also support access to local
enterprise beans."
Does the web container in Sun's J2EE server support access to local enterprise beans?

I'm pretty much sure that you cannot access a
local Session bean from outside the EJB container.Please read the J2EE 1.3 specification before posting messages about EJB and J2EE.
According to the J2EE 1.3 specification:
"The EJB container is required to support access to local enterprise beans. We recommend that the web container also support access to local enterprise beans.
No support is provided for access to local enterprise beans from the application client container or the applet container."
If you use local interfaces for your session bean,
than your client must be local too. A local client is
a client that is collocated in the same JVM with the
session/entity that provides the local view and which
can be tightly coupled to the bean.My client is running in the same JVM as my EJB. The client is a servlet. The servlet is running in the same JVM as the EJB.
For what its worth, the error that I observed occurs during deployment. I haven't figured out why deployment is failing.

No exception is thrown when my server socket dies

I have a server application running on sunOS 5.7.
To this I have both Windows and SunOS clients connected via TCP/IP. (Server built with jdk 1.2.2 and client with 1.3.0)
If the Server socket dies an exception is thrown in the windows clients but not in the sunOS client.
I need the exception to be thrown in the sunOS as well.
Is there anybody who knows how to get this done?
Thanks in advance.
/Henrik

You could poll the connection to see if its there.
If you want the client to register the event then have your client create a sort of listener of your own when it connects. By 'sort of listener' I mean extend the thread class and have it check the connection is not null every n seconds. If it is null then raise the exception yourself.
Would this do it?

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.

How can the eclipse debugger break in the code when an exception is thrown

Is there a way in eclipse to break into the bebugger when an exception is thrown in debug mode like Visual Studio 2003 or 2005?
Thanks

For 3.x, select "Add Java Exception Breakpoint" from the "Run" menu.
Check "Caught" to break even if your code handles the exception, "Uncaught" to break when your code doesn't handle the exception.

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 !!
Thanks

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?

Exceptions not thrown on interrupted SocketChannel.write()

I just noticed a behaviour of java.nio.channels.SocketChannel.write() that makes me wonder. If write() blocks(), and the channel is closed during this blocking by another thread, AsynchronousCloseException should be thrown.
However, in most cases this does not happen in my little test app. If any part of the data passed to write() has already been written to TCP before the socket was closed, write() returns without exception.
Similar behaviour is observed with intterupting. If the thread blocked in write() is interrupted by another thread, it returns immediately and has the interrupted Flag set, but in most cases no Exception is thrown.
ClosedByInterruptException is only thrown if not any part of the data passed to write() has been passed to TCP.
Is this a bug or a feature ?

Yes, i'm pretty sure that it blocks. In my test, the server just accepts the connection and then goes to sleep for a looooong time. The client just connects, and sends 10Meg of fata in one write() call. If i do not interrupt the client, it blocks as long as the server sleeps. In this case, this is the client's stack while blocking:
Thread [main] (Suspended)
     FileDispatcher.write0(FileDescriptor, long, int) line: not available [native method]
     SocketDispatcher.write(FileDescriptor, long, int) line: 29
     IOUtil.writeFromNativeBuffer(FileDescriptor, ByteBuffer, long, NativeDispatcher, Object) line: 104
     IOUtil.write(FileDescriptor, ByteBuffer, long, NativeDispatcher, Object) line: 75
     SocketChannelImpl.write(ByteBuffer) line: 334
     Channels.write(WritableByteChannel, ByteBuffer) line: 60
     Channels.access$000(WritableByteChannel, ByteBuffer) line: 47
     Channels$1.write(byte[], int, int) line: 134
     Channels$1(OutputStream).write(byte[]) line: 58
     SocketClient.main(String[]) line: 75     If i start another thread before calling write(), that closes the socket after 3 seconds, the following happens: The call of IOUtil.write() returns ( with a value n that i cannot see in the debugger ), This value n is tested inside SocketChannelImpl.write() via (n > 0 || (n == IOStatus.UNAVAILABLE), what return true. For that reason, AbstractInterruptibleChannel.end(boolean), does not throw an exception.
Once the server wakes up later, it is able to read about 200K from the socket...
I tried this on a linux system (kernel 2.6.17, glibc 2.4) with jdk 1.6.0_03. I'm now gonna try it under windows, hold on..
Of course, if anybody is interested, i'll post the test proggy...

Exception has occurred during data insertion ... Wrong number of parameters

I am using an ADO dataflow source and an ADO dataflow destination to move data from a table on an IBM iSeries DB2 database to another IBM iSeries DB2 database on another machine. The connection managers for source and destination both use .Net Providers\Odbc
Data Provider with the Data Source Specification being ODBC connections specified on the Windows Server 2008 r2 machine hosting bids. All the test connections work...so far so good.
Issue is when I execute the control flow task the rows get picked up from the source DB2 database no problem but it fails on the insert to the destination DB2 table...The progress tab specifies the exceptions...
[ADO NET Destination [601]] Error: An exception has occurred during data insertion, the message returned from the provider is: ERROR [07002] [IBM][System i Access ODBC Driver]Wrong number of parameters.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "ADO NET Destination" (601) failed with error code 0xC020844B while processing input "ADO NET Destination Input" (604). The identified
component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the
failure.
I put a data viewer on the data flow connection and the records I expect are getting picked up and look ok. I checked to make sure the source and destination tables have the same number of columns in their record layout and identical data
types and they look fine.
Could someone kindly tell me whats going wrong? Does the error message indicate that some of the columns are getting dropped from the dataset before the insert?
Thanks much in advance for any help, Roscoe

Hi Roscoe,
Glad to hear that you have found the root cause. So, the issue occurs because numeric values with no decimal cannot be inserted into the Decimal data type column in the DB2 table. In SSIS, data type Decimal of DB2 database is mapped to data type DT_NUMERIC.
To address the issue, you can do a data conversion for the column in question to define its precision and scale such as DT_NUMERIC(9,2) by using the Data Conversion Transformation before the ADO NET Destination.

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.

Check if an exception is thrown during my JUnit test
