To intercept all exception of GUI Swing?

Blank I tried a method in order to intercept all the exception that can be verified to the inside of a GUI Swing without necessarily to mapping all the code of blocks try & catch.
I was just trying an interface of the class java.lang.Exception in order to try to make a override of the methods, if there is someone that has already experienced this technique.
THANKS

bah, you can throw every exception to the caller method,
and that one can forward it, too
I have never tried this, but maybe you can forward all exceptions to
the main() method, and there should be enough only one try-catch block.
but then you have declare most of your methods to throw something.
I advise you to handle errors at least in a very primitive manner,
only using System.err if you do not want to create some user-friendly,
GUI-based error treatment.
println is very good for debugging and development, use it, really.
First, you can ignore all the exceptions in your code,
and if something goes wrong, just read your console output
for more debug info.

Best way to catch all exceptions

What is the best way to proceed if I would like to catch all exceptions in my Swing app?
If there is an unexpected RuntimeException in my app, I would like to display an error message rather than having the program react silently. Is there a good way of making sure all uncaught exceptions are trapped and reported somewhere in the end? And are there any special inconveniences to such a strategy?

A very similar question was asked recently. Various solutions were proposed in [this topic|http://forums.sun.com/thread.jspa?forumID=57&threadID=5416873] .

Catching all possible exceptions in gui thread

Hi,
I have such a problem: I am developing Swing app and sometimes it crashes by throwing an Exception which I don't catch. The effect is that this exception prints stack trace on System.err but user is not notified and wonders what is happening... I would prefer to show custom ErrorDialog with stacktrace.
I am searching for simple and effective way to catch every possible exception thrown from within any library. I think of a few ways from which everyone has some disadvantages.
The ideal way would be replacing AWT event queue dispatcher so I could process every GUI event inside try { } catch (Exception e) {} block. That would be a good place to catch all exceptions. Unfortunately I don't know if it is possible.
For now I am trying such a solution:
I start background thread together with main app. Then I redirect System.err and System.out streams to PipedStream connected to this background thread. This thread can analyze anything that is going to System.err and maybe recognize potential exception stacktraces. Then it can notify main thread of an exception. But it is not ideal as I have to parse the stream and it can always be not ideal in exception recognition. And the code is quite costly.
Do you have any ideas, had similar problems?

But how can I cause GUI thread to run in my thread
group? As I suppose GUI thread is started by JVM and
is something separate from my code - I can get a
reference to GUI thread but don't know how to
manipulate or replace it...One alternative is to completely separate the GUI code from your code.
Your code, which is wrapped in appropriate try/catch blocks, runs on its own thread and does its own processing. When it's done with that processing, it queues the results on the event thread for display. If an exception occurs during your processing, then you queue something that notifies the GUI.
The simplest way to implement this is to spawn a new thread for each operation. The Runnable that you give to that thread looks like the following:
public MyOperationClass implements Runnable
    public void run()
        try
            // do your exception-generating code here
            SwingUtilities.invokeLater( new MyGUIUpdateClass(param1, param2));
        catch (Exception e)
            SwingUtilities.invokeLater(new MyExceptionReporter(e));
}This is only a bare-bones solution (and hasn't been compiled). Since it separates the GUI from actual processing, you'll probably want to display a wait cursor while the processing thread is doing its thing. You'll probably end up implementing a class that implements this pattern. You may also want to create a producer-consumer thread, so that the user won't invoke, say, a dozen different operations at once.
However, this sort of code is absolutely essential to Swing programming. Most apps do extensive non-GUI processing, such as database queries. If you run such queries in the GUI thread, your GUI will freeze.
Sun has named this pattern "SwingWorker", although I don't think they've fleshed it out very fully: http://java.sun.com/products/jfc/tsc/articles/threads/threads2.html

How to intercept all events sent to subcomponents of a JFrame

Hello.
The title says everything, i think.
I need to make a gui where there would be a user validity timeout if no action is done during a certain period. (then, a modal dialog would show up, asking for a login/pass).
I could do that by modifying each and every swing components to have some date of last use" data, and a thread in the window, bla bla bla... but this is too heavy and crappy to me.
What i would like to do is intercept all events, note the date, and send them normally to who they were sent to originally.
Has anyone an idea?

okay, i've succeeded...
here is the source, in case some ever encounter the problem:
public class TimeoutGlassPane extends javax.swing.JComponent

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 ???

SAP VIM Integrated Invoice Cockpit - single default layout variant for all exceptions

Dear all,
I hope some one has found the solution for this problem we are experiencing in SAP Vendor Invoice Management 600:
For the Integrated Invoice Cockpit ( transaction /OPT/VIM_IIC ) we want to be able to define ONE global layout variant ( available for all users) that is available for all exceptions in the ICC. This so we only have to define and maintain one layout variant centrally.
However this seems not possible: we tried to do so with the transaction /OPT/VIM_EIIC_ADM but it appears that it is only possible to define global layout variants for each exception in the ICC separately ( which is a lot of maintenance work)
Is there a solution available for this ?
Many thanks in advance for your help.
Kind Regards,
Arjan

How do i record all exception in log file?

Hi,
how can i record my all exceptions in a log file? So it is easy for me......thnx.

By using the jdk1.4 Logger class in the java.util.logging package (or an external product like Log4J if you're using jdk1.3 and lower), and putting the log statements in your catch blocks to record the exceptions thrown?

Intercepting all http traffic and forwarding to VIP on CSM?

We would like to intercept all http traffic from clients from all vlans and redirect them to a VIP on the CSM for loadbalancing to 2 proxy servers. Is this possible? I can't seem to find a solution similar to our issue? Please help thanks!

Thx Giles! Do you mean a policy that uses route-maps with next-hop? So would I point the next-hop address to the CSM client vlan IP? Do you have a support link that covers this in detail? Thx!

How to use CALC ALL EXCEPT...

I have some statistics that I don't want aggregated by product. The DBAG says you can do a CALC ALL EXCEPT command but the syntax is not explained very well. I need something like:CALC ALL EXCEPT the member statistics for the dimension All_ProductsI have been doing a calc script to CALC ALL and then to clear out all the parents for ALL_Products for the affected accounts, but it takes a long time.Any suggestions?? Thanks! - Debbie

Depending on your outline it is many times more efficient (time wise)to do a fix ont the members you want (or use a remove list for members you don't want) and do a calc dim of the dimensions that do not have dynamic calc upper level members. also exclude dimensions that don't roll up like scenario. The best use of the Except is when you want to exclude a complete dimensionlike clac all except dim(time);Glenn S.Narratus Solutions

Logging all exceptions

Hi,
I am working on a project where we extend an application built by a third party vendor. I've spent hours trying to determine the cause of some exceptions. The vendor transforms exceptions thrown by the application server or Oracle into their own exceptions. In this process they tend to drop the original cause or message and replace it by a somewhat vague "Database problem probably due to RI violation." not mentioning what constraint caused it. After a long debugging session I managed to figure it out.
I was wondering if I could somehow log all exceptions thrown in the application. I was thinking of some AOP kind of way. Since I don't have the code of the core product classes, I would have to add something at runtime? I believe AspectJ is out of the question since I cannot recompile the vendors code. Spring AOP is out of the question, because I believe it can only add extra behaviour to beans in the application context. We don't use spring at all, so no beans available.
Is there any other way to get to the hidden exceptions or should I just forget about this? I'm going to try to solve some part with jdbc logging first.
Thanks for any input.

I guess if you don't have the code with you, there is no point in exploring the exceptions. Basically they have already catched them.There actually is a point in exploring them: If Oracle throws an exception "Unique constraint YOUR_UNIQUE_CONSTRAINT violated." and all you see is "There was an exception", then there is a good point in getting that exception information. It could be some parameter that you pass to the system that might cause this problem. The way I did it now was telling the eclipse debugger to break at every exception. I honestly hadn't expected to see that application throw so many internal exceptions!

You could slip your own JDBC driver in between the app and the real JDBC driver, give you a bit more insight into what's going on. Write some classes that implement the basic JDBC interfaces, do some logging or whatever, then pass the calls on to your "real" JDBC driver classes. There's at least one open-source project around that already does this, but I can't remember the name of it off the top of me headThanks George, I might do that if I get enough time for it. I found [this article|http://www.rgagnon.com/javadetails/java-0411.html] where they set a logWriter on a DriverManager. This might be enough to capture the jdbc exceptions.

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();
}

CALC ALL EXCEPT MBR problems

Is there an issue with the CALC ALL EXCEPT MBR command with certain members?I load data to members tagged with a UDA as "Direct Load" which should not be consolidated. The member that is being consolidated has an alias of "SSS" (it is in the accounts dimension and 0 level). I need to load data for each quarter in a year as well as the year itself. But when the calc script runs it overwrites the year member. I have tried the following but they do not work:CALC ALL EXCEPT MBR("SSS"); Result: SSS is still consolidated across the time dimension.CALC ALL EXCEPT MBR(@UDA("Accounts","Direct Load")); Result: Error message: "Invalid Calc Script syntax [CALC ALL EXCEPT MBR(@UDA]"Any ideas? We have Essbase Version 5.0.2 Patch 14. What else can be done to keep my direct loads from adding up across time?

The EXCEPT MBR command excludes any Headcount calculations. It does NOT exclude other calculations such as dimension consolidation.If your Headcount member has a formula, Essbase will not calculate the formula. But it will take the existing values and consolidate them across the other dimensions.You probably have a situation where you do NOT have a formula on Headcount. If that is the case, then you want a calc script similar to this one:calc dim (XYZ);fix (@remove (@idescendants (XYZ), Headcount))calc all except dim (XYZ);endfixWhere XYZ is the dimension that contains the Headcount member.
