InvocationException on debugger side but no exception thrown in debuggee

Hi Folks,
in my current project we develop a debugger-like tool. In the tools workflow we call a method of the debuggee via "invokeMethod()" which triggers the debuggee vm to load a class via "loadClass()". When we try to load a class which extends a class from an external library (which was not added to the classpath) then an "InvocationException" is thrown in the debugger (cause: "Exception occurred in target VM"). But when I have a look into the console output of the target VM no exception message can be found. If I call loadClass() directly within the program then Exception "NoClassDefFoundError" is thrown and can be found within the programs console output.
Does anybody have an idea why this exception does not appear within the console output when the debugger is used?
Thanks for your help.
Best Regards
Mario

Presumably you are catching throwable.
It is quite possible that one end is closing down correctly (so no exception) while the other end is expecting something else to happen and thus an exception occurs.
If you are sending messages, not data, and there are no message errors then this is not a problem. Simply catch the exception, note in the code that it not a problem, and eat it.

  • Client side handling of exceptions thrown by a webservice

    I have a webservice that is deployed in Tomcat 5.5 running on Windows XP, Java version is 1.5, using jwsdp 1.5. My client, when run as an applet in a browser (have tried IE 6 and FireFox 1), seems to be unable to parse any exception thrown from the webservice. Instead the following exception is caught by the client:

    If I run the client outside of a browser it catches the exception that is actually thrown by the webservice.
    Is there possibly a problem with the java 5 plugin handling exceptions thrown by webservices?
    I have not found any bug reports or forumn posts regarding this so any assistance would be greatly appreciated.

  • 'exception thrown but not caught' error on the url iview

    Hi,
    EP6, we have url iview that is working fine for displaying a web application. but the problem is some of the link on the web application throws 'exception thrown but not caught' error. it happens to some of the users though.

    Hi Mokone
    I agree with Raghvendranath statement.
    This is not portal side problem.U just using URL of that application
    Also do this
    Open the URLiView editor and check the Fetch Mode property value.
        Launch the same URL in a new browser window (not in the portal).
        Change the URLiView Fetch Mode property from Server-Side to Client-Side.
        The iView is using the Server-side fetching mode but no proxy is defined for the portal
    Hope this info help you

  • Possible to determine exception thrown in a finally block?

    I believe the answer to this is 'no', but I thought I would ask just to confirm.
    If an exception is thrown in a try block, is there a way in the finally block to determine what exception was thrown? I tried using Throwable#fillinStackTrace and Thread#getStackTrace and did not get anywhere. I did see other methods like Thread#getAllStackTraces and perhaps going up to a parent ThreadGroup and inspecting other child Thread instances, but at least in my debugger, I did not see anything useful.
    The basic idea I am trying to achieve is to detect if an exception is thrown in the try, if yes, chain any exception thrown in the finally block to the original exception. I know I can do this on a case-by-case basis by storing the exception caught and then manually chaining it in the finally block. I was looking for something more generic/applicable to all finally blocks.
    Thanks.
    - Saish

    Thanks JSchell, have done that many times in the past.
    I was looking for a more generic (not generics) solution to the problem. So that an error handler could be written to automatically chain exceptions thrown in the finally clause (granted, one still needs to invoke the error handler). My hope was the stack in the finally clause would look different if an exception was thrown in the try block versus none at all.

  • Exception thrown from servlet function

    Hi,
    I have a servlet "main.java" which connects to a database and displays a table. The table contains a check box in front of each table row. It has three buttons at the bottom "add" modify" "delete". When the user clicks on some check boxes and clicks on "delete" button how can i know in the script delete.java that these are the check boxes that have been checked or selected. I tried to do in the following way
                           String[] checkedBoxes = new String[100];
                           checkedBoxes = req.getParameterValues("sel");where sel is the name of the checkboxes
    but I am getting the following error:
    [21/Aug/2001:10:36:54] failure ( 1118): Internal error: exception thrown from the servlet service function (uri=/servlet/delete.class):java.lang.NullPointerException, Stack: java.lang.NullPointerException
    Any help would be appreciated.
    Thanks

    Does every checkbox have the same name, i.e. "sel".
    In this case you're dealing with a checkbox group. Similar to a select-style dropdown or radio button group.
    I know I've had problems with dropdowns in Netscape where the select parameter was not being passed at all, so I'd get null values. I got around this by having the form submission re-assign the value from the select list to a hidden variable and then getting the value from the request.getParameter("hiddenFieldName") instead of the "dropdownFieldName".
    You could try to name each checkbox individually using an appended ID, such as sel1, sel2, etc. and then have these parameters picked up using a loop construct, request.getParameter("sel" + i) -- you may want to pass some value back that would also indicate how many total checkboxes you had so you could determine how many iterations of the loop to go through.
    On the form side, you could probably set the checkboxes up using a similar looping mechanism so that you wouldn't have to explicitly write each checkbox name.
    If this is in fact similar to the Netscape issue I was having with dropdowns, I'd be interested to hear if it'll work in IE.
    I got a bit off-topic, but hope it helps.

  • ERROR: ProviderCaller.run(): exception thrown from IMChannel

    Not sure whether this is better addressed here or in the Instant Messaging forum.
    Basically we're having a problem with the presence service in Portal Server, and it throws a huge exception stack when you do anything except have a blank contact list with noone logged in.
    Portal Server, Access Manager, and IM Server are all installed on the same server in this configuration, and I've tried applying patches to the IM Server APIs to fix the problems to no avail.
    JES 2005Q1
    IM Server patched: 118787-01 118790-01

  • How to properly handle Exception thrown in a .tag file?

    I've got a .jsp file that makes use of some custom tags, each defined in their own .tag file, and located in WEB-INF/tags. I'm having a lot of trouble with the scenario of cleanly dealing with an exception raised by scriptlets in either a .jsp file, and a .tag file. I'm using both Java and Tomcat 6....
    Originally, I wanted to use .tag files in order to componentize common elements that were present in .jsp pages, as well as move ugly scriptlets out of .jsp pages, and isolate them in tag files with their associated page elements.
    Things started getting hairy when I started exploring what happens when an exception is thrown (bought not handled) in a scriptlet in a .tag file. Basically, my app is a servlet that forwards the user to various .jsp pages based on given request parameters. The forwarding to the relevant .jsp page is done by calls to the following method:
    servletContext.getRequestDispatcher("/" + pageName).forward(request, response);
    Where 'pageName' is a String with the name of the .jsp I want to go to...
    Calls to this method are enclosed in a try block, as it throws both a ServletException, and IOException...
    When either my .jsp, or .tag throw an exception in a scriptlet, the exception is wrapped in a JSPException, which is then wrapped in a ServletException.
    I can catch this exception in my servlet... but then what? I want to forward to an error page, however, in the catch block, I can't forward in response to this exception, as that results in an IllegalStateException, as the response has already been committed. So what do I do? How do I get from this point, to my "error.jsp" page?
    It was suggested to me that I use the <% @ page isErrorPage="true" %> directive in my error.jsp,
    and the in my real .jsp, use <%page errorPage="/error.jsp" %>.
    This works great when the exception is thrown in my .jsp.... But when the exception is thrown in the .tag file... not so much...
    My .jsp page was rendered up until the point where the <my:mytag/> (the tag with the offending raised exception) was encountered. Then, instead of forwarding to the error page when the error in the tag is encountered, the error page is rendered as the CONTENT of of my TAG. The rest of the .jsp is then NEVER rendered. I checked the page source, and there is no markup from the original .jsp that lay below the my tag. So this doesn't work at all. I don't want to render the error page WITHIN the half of the .jsp that did render... Why doesn't it take me away from the .jsp with the offending tag altogether and bring me to the error.jsp?
    Then it was suggested to me that I get rid of those page directives, and instead define error handling in the web.xml using the following construct:
    <error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/error</location>
    </error-page>
    <error-page>
    <error-code>404</error-code>
    <location>/error</location>
    </error-page>
    For this, I created a new servlet called ErrorServlet, and mapped it to /error
    Now I could mangle the end of the URL, which causes a 404, and I get redirected to the ErrorServlet. Yay.
    However, exceptions being thrown in either a .jsp or .tag still don't direct me to the ErrorServlet. Apparently this error handling mechanism doesn't work for .jsp pages reached via servletContext.getRequestDispatcher("/" + pageName).forward(request, response) ????
    So I'm just at a total loss now. I know the short answer is "don't throw exceptions in a .jsp or .tag" but frankly, that seems a pretty weak answer that doesn't really address my problem... I mean, it would really be nice to have some kind of exception handler for runtime exceptions thrown in a scriptlet in .tag file, that allows me to forward to a page with detailed stacktrace output, etc, if anything for debugging purposes during development...
    If anyone has a few cents to spare on this, I'd be ever so grateful..
    Thanks!!
    Jeff

    What causes the exception?
    What sort of exception are you raising from the tag files?
    Have you got an example of a tag file that you can share, and a jsp that invokes it so people can duplicate the issue without thinking too much / spending too much time?
    My first instinct would be that the buffer is being flushed, and response committed before your Exception is raised.
    What you describe is pretty much standard functionality for Tomcat in such cases.

    If you have any idea what is going on your help will be greatly appreciated.
    I am using the jdk1.2.2 build and the JavaMail1.2 distribution.
    Thanks,
    William Mapp

    Thanks for the help. Sorry I goofed. Now I have a question regarding what addresses you can send mail to. It seems that if I attempt send mail to a server other than the SMPT host I get a javax.mail.SendFailedException: Sending failed. The exception continues by stating that the address was Invalid, Relaying Denied.
    What does this actually mean? Should i be supplying more information?
    Thanks,

  • Handling exception thrown by parseEscapedXML function

    Hi,
    I am using parseEscapedXML function to parse an xml string in the below format .
    <parameters><item id="" value=""/><item id="" value=""/></parameters>
    The exception thrown when input is in incorrect xml format is not caught using catchAll.
    Kindly check if anyone have any idea about this.

    Hi,
    Ideally your BAPI shouldn't raise exceptions - it is much better to use the RETURN table from your BAPI with any relevant messages - have a look at the majority of standard SAP BAPI's in transaction BAPI.
    This way, the only exceptions your try... catch block needs to handle are those related to the actual calling of your BAPI, not it's functionality.
    Also, if you can successfully run the BAPI in SE37 but it fails when called from your WD application, try using the FBGENDAT functionality to capture what data is being passed to SAP from your Web Dynpro application.  All it takes is a simple mistake in setting up your contexts or logic and you won't be calling your BAPI correctly.
    Hope this helps,
    Gareth.

  • Catching an exception thrown from another thread

    I have a SocketServer that creates new threads to handle incoming clients. If one of the threads throw a SQLException is it possible to catch that exception in the SocketServer that created that thread.
    I tried implementing this code and I cannot get the server to catch an exception thrown in the thread. Are my assumptions correct?
    I was reading something about Thread Groups and implementing an uncoughtException() method, but this looked like overkill.
    Thanks for your time!
    Some Example code would be the following where the ClientThread will do a database query which could cause an SQLException. I'd like to catch that exception in my Socket Server
          try
                 new ClientThread( socketServer.accept() , host, connection ).start();
          catch( SQLException e )
                 System.out.println( "DataSource Connection Problem" );
                  e.printStackTrace();
          }

    hehe, why?
    The server's job is to listen for an incoming message from a client and pass it off to a thread to handle the client. Otherwise the server will have to block on that incoming port untill it has finished handling the client and usually there are many incoming clients continuously.
    The reason I would want to catch an exception in the server based on the SQLException thrown in the thread is because the SQLException is usually going to be due to the fact the datasource connection has become unavalable, or needs to be refreshed. This datasource connection is a private variable stored in the socket server. The SocketServer now needs to know that it has to refresh that datasource connection. I would normally try to use somesort of flag to set the variable but to throw another wrench into my dilemma, the SocketServer is actually its own thread. So I can't make any of these variables static, which means I can't have the thread call a method on teh socket server to change the status flag. :)
    I guess I need implement some sort of Listener that the thread can notify when a datasource connection goes down?
    Thanks for the help so far, I figured java would not want one thread to catch another thread's exceptions, but I just wanted to make sure.

  • Help Me, How to catch exception thrown from ejbStore

    Hi,
    I am working on application running on Iplanet Application Server 4.0. Problem is the application exception thrown from the ejbStore don't reach the calling servlet, calling servlet receive TransactionRollback exception which is system exception. But there is no sign of my application exception thrown from ejbStore. Can anybody tell me how I can get my ApplicationException thrown from ejbStore in my calling servlet.
    I am calling entity beans set method in servlet and in entity bean ejbStore method I am throwing Application exception.
    in entity bean
    public void ejbStore() throws MyException
    if(true) throw new MyException();
    in servlet
    try {
    MyEntityHome home = .......
    MyEntityRemote remote = home.findBy.....
    remote.setMyValue(MyValue value); //Transaction required Container managed
    }catch(MyException e) {
    e.printStackTrace(); // Not cahcing My Exception
    }catch(Exception e) {
    e.printStackTrace(); //catching TransactionRolledBackException

  • Lots of exceptions thrown

    Hi,
    We are switching to test our codes based on JRockitRealTime 3.0.0, 1.6, linux 64 from Sun HotSpot.
    We notice a quite a few things are significant slower when compared to the results based on HotSpot.
    Turning on the Xverbose:exceptions=debug, we see lots of exceptions thrown, the following is just 1 example of many (with different kinds of stack trace too). And we believe they are the main cause to the slowdown. Can you help explain why we're getting the exceptions and how to resolve them? We did not see the exceptions from running HotSpot JVM, and looks like there is no need/way to turn on the exception traces from HotSpot HVM so we assume there were no exceptions thrown when we ran our applications based on HotSpot JVM. Interestingly, even with the exceptions looks like our applications still function ok, that make me to think is it this something internal to JRockit?
    Regards,
    Jasper

    Turning on exception printouts with -Xverbose:exceptions will print out all exceptions being thrown, whether they are caught or not. It is not unusal for programs to cause execptions as part of their normal execution and to catch them silently. -Xverbose:exceptions is primarily a debugging and supportability tool.
    Thus, it is highly likely that the same number of exceptions are thrown when running with Hotspot, but there are no debugging tools available for Hotspot that will show these exceptions.
    To analyze the slow down you are seeing, I would suggest that you do a JRA profiler recording (part of JRockit Mission Control) and see if there is anything in that data that looks suspicious (such as long GC pauses or method bottlenecks).
