Catching all Throwables

Hi all,
What is the best way to catch all Throwables, e.g. Errors and Exceptions? I want to catch all Throwables appearing in my app in all Threads even in the EventQueues etc.
Thx for any hint, Mathias

What about catching every output to System.err? I
think every stacktrace is going to System.err. But how
do I know when an output is finished, e.g. when to
popup my dialog? As someone has pointed out this is a very bad idea. A dialog presumes that the GUI is working. What if the gui is throwing the exception? What if your exception dialog is throwing the exception....
exception thrown, dialog starts and throws exception,
dialog starts and throws exception,
dialog starts and throws exception,
And I am not repeating myself above. That is what your code is going to do.
I always catch throwable. I put it in main, I do a printStackTrace and then I exit the app. I am hopeful that it will print the stack trace. And even if it doesn't then the app will still end.

How to catch ALL Exception in ONE TIME

I'm explain my issue:
I'm making a program with Class, Swing, Thread ...
Then all action I do on my graphical application, I use a new thread, well
I want to capture in my Startup programs, all unknow exception and then, I display it with a JOptionPane for example
In fact, I want to do something like Eclipse, when it crash, I capture the error
Could you help me ? Tell me the best way to do that ?
This is an exemple
FILE: Startup.java
class Startup{
public static main (String args[]){
try{
new Main();
}catch(Throwable e){
//Message d'erreur fenetre
FILE: Main.java
class Main{
Main(){
init_action();
void init_action(){
mybutton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Thread th=new Thread(){
public void run(){
int a = 1 / 0;
th.start();
Well, in this example I want to capture the Divide By 0, I use the Throwable Exeption, in order to be sure I catch all unknow exeption
Then, a good job, is to put throws Throwable in all function
but Thread, and ActionPerformed ... could not implement it
How to put this exception and jump it to Startup Program ?

I already do that, what can I do for improving capture ?
That's impossible ... It will be a great idea to make a Redirection of Error to a Exception class in futur version
For example, when an unknow error arrive, don't show it on console and crash ... but run a class redirector exception, and magic, it show you a beautiful error warning, and stop properly the programme ...
I put an error class, and put try {] catch {} everywhere, and run my exception class,
this class detect the error exception and run a properly beautiful and clear french message (I'm french :d)
Well, If you have the BEST other idea, tell me, I read your message with a lot of regard
see you soon
bye

Trying to catch all exceptions...

Hi, developers!
I am trying to develop the best code, that can catch all the exceptions, in the best possible way, and whenever as possible it must register in a log with informations about the exception occurred.
I need your suggestions. See the code below:
MyClass()
throws IOException, MyException {
Throwable objThrowable1 = null;
try {
    doSomething();
} catch(MyException e) {
    objThrowable1 = e;
    throw e;
} catch(IOException e) {
    objThrowable1 = e;
    throw e;
} catch(RuntimeException e) {
    objThrowable1 = e;
    throw e;
} catch(Exception e) {
    objThrowable1 = e;
    throw new Exception("Some Exception occurred.", e);
} catch(Error e) {
    objThrowable1 = e;
    throw e;
} finally {
    if (objThrowable1 != null) {
      Throwable objThrowable2 = null;
      try {
        log.fatal(objThrowable1);
        objThrowable1.printStackTrace();
      } catch(RuntimeException e) {
        objThrowable2 = e;
        throw e;
      } catch(Exception e) {
        objThrowable2 = e;
        throw new Exception("Some Exception occurred while logging.", e);
      } catch(Error e) {
        objThrowable2 = e;
        throw e;
      } finally {
        if (objThrowable2 != null) {
          objThrowable2.printStackTrace();
}It is the constructor of MyClass, and it might throw IOException or MyException.
Now some questions:
1) Do you think I exaggerated and wrote a lot of code, more than sufficient?
2) I wrote all this code because I think it�s a good idea throwing exceptions, especially RuntimeException and Error. The Virtual Machine must know how to handle the situation when some exception occurs. But I want to register a log of the exception, too, whenever as possible. In my opinion, the only way to advise the Virtual Machine that some exception occurred is throwing this exception. Do you agree? Do I really need to worry about it?
Thanks in advance!

Hi, developers!
I am trying to develop the best code, that can catch
all the exceptions, in the best possible way,Define "best possible way". I don't think what you're proposing is even close, by any measure.
You should only catch exceptions that you intend to handle. If there's no way for your class to handle the exception, it should bubble it up to the class that will. Catching and rethrowing like that seems a total waste to me.
I need your suggestions. See the code below:I'd suggest that this is an ugly mess. I would not go this way.
I have no idea whatsoever about that finally block. That should be for cleanup. What are you doing there?
MyClass()
throws IOException, MyException {
Throwable objThrowable1 = null;
try {
doSomething();
} catch(MyException e) {
objThrowable1 = e;
throw e;
} catch(IOException e) {
objThrowable1 = e;
throw e;
} catch(RuntimeException e) {
objThrowable1 = e;
throw e;
} catch(Exception e) {
objThrowable1 = e;
throw new Exception("Some Exception occurred.",
d.", e);
} catch(Error e) {
objThrowable1 = e;
throw e;
} finally {
if (objThrowable1 != null) {
Throwable objThrowable2 = null;
try {
log.fatal(objThrowable1);
objThrowable1.printStackTrace();
} catch(RuntimeException e) {
objThrowable2 = e;
throw e;
} catch(Exception e) {
objThrowable2 = e;
throw new Exception("Some Exception occurred
occurred while logging.", e);
} catch(Error e) {
objThrowable2 = e;
throw e;
} finally {
if (objThrowable2 != null) {
objThrowable2.printStackTrace();
}It is the constructor of MyClass, and it might
throw IOException or MyException.
Now some questions:
1) Do you think I exaggerated and wrote a lot of

A catch-all "exception handler" - what's the end of an stack trace?

I've created an application that is beeing tested these days, and I thought it would be a good idea to implement a "catch-all" exception handler so that I could notify the user when an exception occur (so that he may stop, send me the log, and to prevent errors that occur as a result of the first one).
The way I've started implementing it is I redirect error out to a custom output stream:
public class ConsoleOutStream extends ByteArrayOutputStream {
    private JFrame owner;
    public ConsoleOutStream(JFrame owner) {
        this.owner = owner;
     * Writes <code>len</code> bytes from the specified byte array
     * starting at offset <code>off</code> to this byte array output stream.
     * @param   b     the data.
     * @param   off   the start offset in the data.
     * @param   len   the number of bytes to write.
    public synchronized void write(byte b[], int off, int len) {
        super.write(b, off, len);
        checkForExceptions();
     * Writes the specified byte to this byte array output stream.
     * @param   b   the byte to be written.
    public synchronized void write(int b) {
        super.write(b);
        checkForExceptions();
    private void checkForExceptions() {
        reset();
        if(this.toString().indexOf("xception") != -1) {
            System.out.println("Exception!!\n\n");
            System.out.println(this.toString());
}then i redirect System.err:
PrintStream out = new PrintStream(new ConsoleOutStream(this));
System.setErr(out);
The problem is that the checkForExceptions() method will be called, e.g. 3 times for each exception - and I just want to display an error message to the user once (of course).
Anyone done something similar?

I'm interested in catching all "unhandled errors"how about:
public static void main(String[] args){
    try{
    //whatever you would normally call from main
    }catch (Throwable e){
         System.out.println("There was an unhandled exception:");
         e.printStackTrace();
}

BPEL catch all block doesn't catch fault

Hi,
I have a catch all block in my BPEL process. One instance tried to write to the Oracle database without success throwing a fault which wasn't taken by BPEL's catch all. I see an error on invoke but it does not go to catch all block.
Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'merge' failed due to: DBWriteInteractionSpec Execute Failed Exception. merge failed. Descriptor name: [writeCountry.Country]. Caused by java.sql.SQLRecoverableException: No more data to read from socket. Please see the logs for the full DBAdapter logging output prior to this exception. This exception is considered retriable, likely due to a communication failure. Because the global transaction is rolling back the invoke must be retried in a new transaction, restarting from the place of the last transaction commit. To classify it as non-retriable instead add property nonRetriableErrorCodes with value "17410" to your deployment descriptor (i.e. weblogic-ra.xml). ". The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution.
Global retry rollback fault thrown.
The current JTA transaction is aborting due to an user rollback fault being thrown. The upstream component should retry in a new JTA transaction upon catching this fault.
This exception was caused by a global retry fault being thrown from downstream component. The user had directed the BPEL engine to roll back the current JTA transaction and retry within new JTA transactions for the specified number of times and retry interval.
There is no action recommended.
Ah, I have one more question, I have a BPEL process wich write to the database to the table X. Some time ago i extended the table X and add one more column. Why does BPEL lost all data in dbadapter and does not sygnalize any error when invoked adapter? Usually when I drop or alter table i get an error message. This time I see that the transformation which was before invoke to dbadapter was done correctly but I can see no data in invoke which should be written
All environment is on 11.1.1.6, BPEL 2.0
Edited by: 863909 on 2012-08-29 01:05

Aye. My catch all block is defined for a parent scope. Just some arrors are not catch by catch all block (the same as for OutOfMemoryError for java - which will never be catched). I just wonder, because my red invoke activity in the EM sygnalizes error and throw error message but catch all block does not get it. Process stoped on error invoke and not go into catch all.
Change table aspect. I don't have a problem, because i deleted old and implemented new adapter. It works. I just wonder why when I deleted an atribute (column) from DB I got en error and process stops, but when I extended a table, my process were runing to the end and was marked as finished completely. Something is wrong here, because adapter didnt write all data it should write. Process were going and was finished without throwing an error.

Catch all error information while validating xml content with xsd schema

Hi experts,
I created a java mapping to validating the input xml content with xsd schema (schema validation). What I want is to catch all error message to the xml not just the first error. I used SAXParser in sapxmltoolkit.jar to do the schema validation. The below is a part of my java mapping.
XMLReader parser = XMLReaderFactory.createXMLReader("com.sap.engine.lib.xml.parser.SAXParser");
parser.setFeature( "http://xml.org/sax/features/validation" , true);
parser.setFeature( "http://apache.org/xml/features/validation/schema" , true);
parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");          parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource",this.getClass().getClassLoader().getResourceAsStream(schema)); // schema is my schema name
parser.setErrorHandler(new ParseErrorHandler()); // ParseErrorHandler is my own ErrorHandler which extends DefaultHandler
parser.parse(new InputSource(new ByteArrayInputStream(sinput.getBytes())));
// In error handler, I comment all code so as not to throw any exception
public class ParseErrorHandler extends DefaultHandler
     public void error(SAXParseException e) throws SAXException
          // sSystem.out.println("Error" + e.getMessage());
          // throw e;
     public void fatalError(SAXParseException e)
          // throw e;
          // System.out.println("SAP Fatal Error" + e.getMessage());
Unfortunately the program always stopped while catching the first error. Check the below log.
com.sap.engine.lib.xml.parser.NestedSAXParserException: Fatal Error: com.sap.engine.lib.xml.parser.ParserException:

Best Practice: JavaFX pattern for "Catching all Exceptions"

Hi,
what is on the current JavaFX Standard the best way to catch all Exceptions (centralized) within my JavaFX application...
I read thread outside this Oracle Forum who recommend following:
1. Thread.setDefaultUncaughtExceptionHandler(new MyExceptionHandler());
--> catch all runtime exceptions
2. http://stackoverflow.com/questions/12318861/javafx-2-catching-all-runtime-exceptions
--> Implementing some source code who wrap the current GUI thread...
3. I read something like:
"JavaFX exception handling is almost identical to that in Java, apart from the fact that checked exceptions are handled in the same way as unchecked exceptions. This is good news for most Java programmers moving to JavaFX because you are no longer obliged to catch and handle exceptions."
Sounds very good! But where/how can I do this ???

ICP Mappings being picked up by Catch all and not by like mappings???

Hello,
In FDM we have set up mapping tables for Account and ICP. In the source G/L the account drives both Account in HFM and ICP. Both of the mappings are the same:
???-3950-000 account mapps to 3111315
???-3950-000 ICP maps to CORUS117
When I validate the file the account gets picked up correctly but the ICP get picked up by the catch all of * -> [ICP None].
If i change the like mapping to an explicit mapping it works, can anyone help?
John

In your like map does the *->ICP None come before the ???-395-000 mapings?
If yes put the ??? above the *.

Mail 4.5 not retrieving catch-all mail from Pop Server.

I use email fowarding for a domain (hosted at Godaddy) to forward to my verizon email account. For example: [email protected], [email protected], and [email protected] are forwarded to [email protected] The Mail 4.5 client on my MacBook Pro (OSX 10.6.8) retrieves all this forwarded email correctly from the Verizon Pop3 server.
I also have one of the domain email aliases setup as a catch-all account. For example [email protected] is configured as the catch all. Mail addressed to [email protected] is also retrieved from the Pop3 server correctly.
But any mail directed to the catch-all account because the email address is invalid such as [email protected] is not retrieved by Mail 4.5 client.
The 'catch-all' email is being forwarded correctly to my Verizon Pop server. If I log in to Verizon Webmail I can see the forwarded 'catch-all' emails in the Webmail Inbox. Also if I use Outlook 2010 on my PC to retrieve my Pop mail, it correctly brings down the 'catch-all' email.
It certainly appears like something internal to Apple Mail is filtering the 'catch-all' email and not retrieving it from the Pop3 Server.
If you can understand what I'm trying to report - can you help me figure out what is wrong?

I now do want to catch all email as it has become my lives work to report spam.
So I figured out an easier way to catch all email using simply the serveradmin command-line tool (this only takes email that would otherwise bounce):
sudo serveradmin settings mail:imap:lmtp_luser_relay_enabled = yes
sudo serveradmin settings mail:imap:lmtp_luser_relay = catchallusername
sudo postfix reload

Catching all errors

Hi
is there a way to catch all errors, I know you can do try and
catch fro your code
about how about errors that come from built in Flex component
I am trying to catch all errors and show it to the user in
better format
but most important, it seems flex will be frozen and you can
do anything if the error is not caught and the only way around it
to restart your browser
Please help
Thanks
Kasem

Everything I read suggests that this isn't possible in Flex.
It seems that uncaught exceptions are handled by the Flash player.
This link discusses the problem in Flex 1.5 and it notes the
problem is not fixed in Flex 2.
http://www.mail-archive.com/[email protected]/msg25874.html
I'm going to continue to look. I really can't imagine that
Adobe spent all that time reworking Flex and didn't address this
problem.

How can I hide "Taxonomy Catch All Column" without using PowerShell?

After having moved some files around, I find that my view and edit properties forms include the field "Taxonomy Catch All Column" and the field IDs which are just going to be confusing gobbledegook to my end users.
I can't seem to find a way to get rid of it. I can't delete it and I can't see where to hide it. Searches only seem to turn up PowerShell script solutions, and I can't use PowerShell.
It's SharePoint 2010 Server, I'm a site admin and I can use SharePoint Designer, but not powershell, no server access, no central admin access.
Can anyone help please?

Hi,
For your issue, it seems to be related to use Content & Structure.
If you choose to move content that contains managed metadata columns (or presumably enterprise keywords), the Taxonomy Catch All column shows up after you use the "Content and structure" tool. It shows up as a column in the library and is visible
in "Edit Properties" on every document.
Why are you can’t use power shell? It is convenient to solve your problem with power shell.

Email app doesn't open catch-all folder at start-up

Hi,
I'm happy the email app got redesigned and a new catch-all folder has been introduced. I wonder though why it doesn't open this folder by default. Instead it jumps right to the folder underneath which is a folder linked to 1 of the 4 email accounts I'm checking with Iphone. It's not even the default email account....

Okay, had to "Reboot" my phone. Hope it doesn't recur. Wait, this is Apple not Microsoft.
Actually I could connect to the App store either, so not a Gmail problem. But I COULD text okay. Strange.

Catch All Exception

Hi,
I'm quite familiar with Oracle SOA, OSB , CEP stuff. Just exploring BPM and here i have a question on error handling.
I see we can catch all system or business exceptions using a event sub process. and handle it. But i see no means to see what the error message is?
Lets say i would like to email admin with the error message, from where can i retrieve the error message from?
Any pointers on this is much appreciated.
Thanks,
Prakash

I think you can use Error Events (Component Palette, from the Catch Events section select Error Event) and then log it or email it .

Configure a Catch-All Mailbox in Exchange 2013

Is it possible to create a catch-all rule which delivers mail sent to a non- existing mail address inside the organization (*@contoso.com), to a specific
mailbox?
Exchange 2013 Standard

Hi All
I have also used the Catch all agent from Codeplex, with great success.
The only issue is, that the catch all transport agent HAS TO be installed, while your still at level CU3 or lower.
We are now at exchange 2013 CU7, and the Catch all agent still works like a charm.
Forget about journaling rules, these doesn´t work, in my experience
