Exception Handling In Struts, Declarative, programatic and customized excep

hello .
I'm workingon exception handling in struts , i executed the gobal exceptions.
In glabal exception handling , one will not get the root cause of exception , rather we print the message from resource bundle.
How to get the root cause of exception in jsp page.
Give me sample code to deal with ExceptionHandler claas.
Thank u
Roshu

Hi ,
I am in the same situation. Global exception is working fine in my struts application . But I need to show the exception stack trace also in the screen whenever the exception occurs.Can anyone please provide me a sample code to deal with ExceptionHandler class ?

It takes long time to invoke the Exception handler code

In our setup there is firewall between the Appserver that is using toplink and the database.The firewall terminates idle connection on any port if the connection is idle for 1 hr.So i have implemented an exception handler to reconnect when the connection is broken.The code works fine but It takes 15 mins for the exception handler code to be invoked.
The database is Oracle and the driver is thin driver,OS is solaris.No external connection pool
I had registered the exceptionhandler to the serversession,should i register it with each ClientSession?

yes ,15 mins is the time taken before the server session's exception handler code is invoked.
The following is the exception handler code on the sever session.Any thing wrong?
server.setExceptionHandler(new ExceptionHandler()
public Object handleException(RuntimeException ex)
{//This method is executed only after 15 min ,if the connection is broken
String mess=ex.getMessage();
System.out.println("In handler excep mess is "+mess);
if ((ex instanceof DatabaseException) && (mess.equals("connection reset by peer.")||(mess.indexOf("IOException :Broken pipe")!=-1)))
DatabaseException dbex = (DatabaseException) ex;
dbex.getAccessor().reestablishConnection (dbex.getSession());
return dbex.getSession().executeQuery(dbex.getQuery());
return null;
What could be wrong ?
I tried Oracle's connection cache Impl created a connection pool using the same thin driver and on the same env.SQLException is thrown immediately on using the broken connection.so I feel the driver is not causing any problem.
Is there any way in toplink to keep the connections active?or Is there any way to poll all connections in the connection pool and check If they are connected instead of waiting until the exception gets thrown and handle it?

BPM Exception Handling control step

Hi,
Does anybody have any idea, whats the variable we need to pass in the control step of exception handling in BPM? and how to map the error message back to the RFC Response.
I had Transformation step, in that mapping is also there.
Is there any ideas??.
Thanks,
Raj.

Hi,
The requirement was to send the exception that occured to a target (say file).
insert a block for the exception
You cannot place an exception step without a block right... thats what i mean by the above statement.
Now, just after the exception has taken place, if i put a transformation step, and a send step, you will be taking care of sending the exception message to the target.
how to build the exception message ? It should map from what?
You could build a data type for the exception.
In the mapping, you could map it to constants. For ex:
if you build your DT as
<excep>
<code/>
<desc/>
</excep>
You could map the description to a constant string "timeout".
After this, the send step will send the message to the file, through the abstract interface that you create.

Smitha.

RE: exception handling

Wayne,
When an exception occurs, Forte aborts the inner
most compound statement, after executing the code
of an exception handler if there is one. If the excep-
tion is not handled, it still exists after the compound
statement was aborted, so Forte now aborts the
remaining inner most compound statement. This
continues until Forte reaches the root compound
statement of the tread (or "task" if you will). This
one will also be aborted and that is the end of the
thread (task). If you look at the debugger, you will
see "RIP" in front of this thread. Sure, this thread
was spawned by another thread. It was started
by a "start task" call from within some compound
statement in the parent thread, but this compound
statement was probably long since closed. Forte
can't pass the exception on to a higher level com-
pound statement, because there is none. If the
thread started with a method that had a return event
and an exception event, and you started the task
with "Completion = event" then Forte will post one
of these events after the root compound statement
was finished (in other words, the thread was stopped).
From this event you can see, if the thread wasfinished succesfully or not.
Of course, an event is not the same kind of thing
as an exception. You can't raise events, or post
exceptions.
So, when an exception is not handled, only the thread
where this exception occured is cancelled (including
all it's child threads). The rest of the treads stay alive.

Subject: exception handling
I have a problem in handling exceptions detected in a task. I start a
task
which performs some function. I also have an event handler which
recognizes the method_exception returned should an exception be
detected.
Once detected by the event handler I force the exception up to
another
process which displays the exception to the user. However, it appears
that
forte is intercepting the exception before my event handler can detect
it
and posts an exception message. Can anyone explain how this mechanism
works and the best approach for handling exceptions myself vice Forte?
Thanks,

My understanding is that if your client doesn't care (or cannot handle) the exception,
you throw your exception WRARPPED with EJBException. This way, the container can
roll back the transaction properly.
If your client cares (or have the ability to recover) the exception, you should
define your own exception. They should not be derived from RuntimeException or
RemoteException or EJBException. If you want to make sure that the transactions
are rolled back, you call setRollbackOnly() before you throw the exception.

Does that mean to say you can't have custom exceptions thrown to a client?

Hi, I ran into Sam problem. I have the Eclipse 3.1.0, JBOSS 4.0.1sp1, JBoss-IDE 1.3.0 running under JDK 1.5.0.02. It appers for sum resion that the jboss-web.xml is not getting the name of the �<ejb-ref-name></ejb-ref-name>�. if I manually add the name so it looks like this: �<ejb-ref-name>ejb/Fibo</ejb-ref-name>� the project deploys. I am new to this as well and am not shore what needs to be changed to fix this in the build. I am thinking it�s a problem in the way XDoclet parses the source for the META DATA.

Handling of free goods in PO

Dear ALL,
Our vendor has agreed that he will give us one drum of oil free if we buy 100 drums from him.
how can we bifurcate this in the system that 100 drums we have purchased and one is as a free good.
1) what we have to do when raising a PO ?
shall we make PO with 101 drums and select FREE indicator in PO.In this case all 101 drums will become as free goods.
2) or if we raise a PO for 100 drums without selecting free goods indicator how shall we handle at the time of GR of 101 drums. in this case GR of 101 drums will be treated by system as overdelivery.
3)how can we maintain free goods information in PIR( Purchase info records)
Request to suggest steps in dealing with this scenario.
regards
ajay

Hi Ajay,
One way is create 2 line items in PO, one line item with 100 no's and 2nd line item with 1 number which should be checked with free goods.
At the time of GR do the GR for both the line items.
Hope this helps.
Thanks,
Viswanath

Get Attribute values from a page and procedure exception handling?

Hi All,
I have created new page with two input attributes not based on any VO. This page is created to capture two values and pass these to an AM method upon pressing OK button. The method in AM will call a procedure with two in parameter expecting the two values captured from the above said page.
I have two questions, first one how to capture the values entered by the page in the controller class and advises me how to handle exceptions when my procedure fails.
I can not use something like this since this page is not based on a VO
String fromName = (String)vo.getCurrentRow().getAttribute("FromName");
Do I have to create a dummy VO like select '' name1, '' name2 from dual?
Thanks for the help.

Hi,
Actually you can capture the parameters on the page like this way
String test = (String)pageContext.getParameter("id of the text input bean");
Now in procedure you can take an out parameter which stores the error messages on exception
and return that out parameter in java.
and then you can throw exception on page using OAException class.
Thanks

Report handling names with a single quote

Report 10gR2
I have created a report and most of the functionality that i want is working as expected.
I have a report where i am letting user enter their first name on one field and last name on another field in the parameter screen ( thats how it's stored in the database)
If they enter any name with an aphostrophe , say D'Costa ( either first name or last name)
then i get the below error
REP-50003: Bad parameter: pfaction=http://.........
I am using like keyword as seen below in the afterparam trigger and passing the parameter :p_where_last_name to the main sql query
:p_where_last_name := ' AND UPPER( :last_name) LIKE (' ||''''||'%'||UPPER(:last_name)||'%'||''''||')' ;
Whats the best approach to handle this issue
Also is there a way to capture this error
' REP-50003: Bad parameter: pfaction=http://.........
' and display a message, if so where and how, please advise.
thanks.
Edited by: Forms_Reports_Beginner on Aug 13, 2009 1:52 PM

I am not using form , it's just done in report, that is i am not calling the report from a form , just from a menu.
:last_name is a report_paramter that i created on the report.
you're right the first assignmnt is
AND UPPER( db column) LIKE
I have a paramter form on the report with a field last name and I am letting the user enter last name there which gets stored in the :last_name

Rodolfo,
your solution works,
:p_where_clause := ' AND UPPER( db_column ) LIKE (' ||''''||'%'||UPPER(Replace(:p_2,chr(39), chr(39)||chr(39)))||'%'||''''||')' ;
but i dont quite understand how this is working
Replace(:p_2,chr(39), chr(39)||chr(39))
i have never used chr

Can FDM handle more than one year at a time?

Hi,
I'm trying to load a multi-load file through FDM with the target being an Essbase cube and the source being a text file. The file is for 36 months which crosses 3 years. The problem is Oracle support is saying FDM can only handle one calendar year at a time and we need to load 3 separate files.
The file imports and validates ok. And the export only pushes data to the first year '2010' but it doesn't error out.
Any ideas?

If you use an excel file as the source, you can load all 36 periods.
You can also modify the adaptor to support this action but I would caution you that doing so will cause support to no longer support your application without requiring you to import a non customized adaptor. This also has consequences for when upgrading.
Let me add, FDM support is the best in the business. I have never had a situation where what they told me was incorrect. What you are trying to accomplish would be a custom solution that should be implemented by an experienced FDM resource that understands the impact of the customization.

How can I execute an external program from within a button's event handler?

I am using Tomcat ApacheTomcat 6.0.16 with Netbeans 6.1 (with the latest JDK/J2EE)
I need to execute external programs from an event handler for a button on a JSF page (the program is compiled, and extremely fast compared both to plain java and especially stored procedures written in SQL).
I tried what I'd do in a standalone program (as shown in the appended code), but it didn't work. Instead I received text saying the program couldn't be found. This error message comes even if I try the Windows command "dir". I thought with 'dir' I'd at least get the contents of the current working directory. :-(
I can probably get by with cgi on Apache's httpd server (or, I understand tomcat supports cgi, but I have yet to get that to work either), but whatever I do I need to be able to do it from within the button's event handler. And if I resort to cgi, I must be able to maintain session jumping from one server to the other and back.
So, then, how can I do this?
Thanks
Ted
NB: The programs that I need to run do NOT take input from the user. Rather, my code in the web application processes user selections from selection controls, and a couple field controls, sanitizes the inoputs and places clean, safe data in a MySQL database, and then the external program I need to run gets safe data from the database, does some heavy duty number crunching, and puts the output data into the database. They are well insulated from mischeif.
NB: In the following array_function_test.pl was placed in the same folder as the web application's jsp pages, (and I'd tried WEB-INF - with the same result), and I DID see the file in the application's war file.
        try {
            java.lang.ProcessBuilder pn = new java.lang.ProcessBuilder("array_function_test.pl");
            //pn.directory(new java.io.File("K:\\work"));
            java.lang.Process pr = pn.start();
            java.io.BufferedInputStream bis = (java.io.BufferedInputStream)pr.getInputStream();
            String tmp = new String("");
            byte b[] = new byte[1000];
            int i = 0;
            while (i != -1) {
                bis.read(b);
                tmp += new String(b);
            getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + tmp);
        } catch (java.io.IOException ex) {
            getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + ex.getMessage());
        }

Hi Fonsi!
One way to execute an external program is to use the System Exec.vi. You find it in the functions pallet under Communication.

XFi Can't Handle more than one sound at a time?!?

I bought an XFi Elite Pro and it was working great. Now, however, it will only handle one sound at a time. For example, if I'm playing a song in iTunes and windows makes a sound, the itunes song cuts out, the windows sound plays, then itunes abruptly cuts back in. Same thing in games. If I'm playing Warcraft the sound will cut out if Windows makes some kind of a sound.
How do I get my card back to being able to play multiple sounds/music simultaneously? I'm running Vista Ultimate on a Quad Core system with 4 gigs of RAM.

Sound like something messed up somehow. Maybe you can consider reinstalling the drivers again? @28.86.2.0
