  • Source Not Found Error while Debugging

    Hello,
    I get annoying Errors while debugging a midlet. I reinstalled all programms an created a new midlet suite + midlet but the error is still there and the Midlet doesnt start.
    i got Eclipse Version: 3.2.2, Eclipse ME 1.6.6, the newest WTK 2.5 and java.vm.version=1.6.0-b105.
    I configured everything like www.eclipseme.org says it would be correct.
    Running a Midlet works fine.
    The bug opens an Helper.class file which says:
    Class File Editor: Source not found: "The Jar of this classfile belongs to the container J2ME library [ Sun Java (TM) Wireless Toolkit 2.5 for CLDC/MediaControl]. To configure the source attachment, go directly to the corresponding configuration page (For example for JRE go to 'Installed JRE#s page in references).
    Any clou how to fix this?? I need to debug my midlet :-/
    THANKS!

    Hi,
    I just had the same problem and navigated to this page here in hope for a solution...
    However I've solved the problem now. On Eclipse, do the following.
    1) Right-click on the added Jar-file (which is producing the problem)
    2) On the popup-menu choose "Build Path" and "Configure Build Path..."
    3) On the opening preference window, click the checkbox of the Jar
    This is probably necessary because the jar has to be exported such that the simulator is able to execute it.

  • Error while debugging in NWDS

    Hi,
    I am getting a "source not found" error while debugging in NWDS.
    I put a break point in a particular class, but it never gets hit, instead I get an error saying "source is not found".
    I have tried rebuilding, deploying and even starting the IDE but nothing works.
    Can anybody help me here.
    Regards
    Arvind

    Hi Arvind,
    1) Have you set debug on in the server?
         If not you need to on debug on SAP-J2EE engine(For web applications).
    2) If that is a pure java class then it will work.

  • Error while testing ITS Connection

    Hi all:
         There is an error while testing ITS Connection,  it says the 8000 port is a closed point by the firewall ,  but according to the
    administrator of intranet,  there is no firewall between ECC and Portal, I guess I should add port 8000 into service file ? I mean the file of Host and Service, am I right ?
    An HTTP/S connection to http://10.180.80.171:8000 was not obtained successfully; this might be due to a closed port on the Firewall.

    thank you very much for your help. for update server's full name, may I put the mapping values  into host file in the format of  <ip address> <hostname.domain name> <hostname>, do you think it is OK?
    in the second blog you suggest there is something about Server port(please refer to the following):
    in the window machine, there should be an entry like sapms<SAP System ID> , can you please give me a full example:
    let's say my system ID is EC1,  so it would be sapmsEC1  8000/tcp, right ?
    Here you have to enter the port of your application server. By default this is 80<SAP System ID>. But your basis administrator can modify this setting, thatu2019s why you should check it in the transaction SMICM (Goto -> Parameters -> Display). For example the IBSolution Development System Erinome the port is 8000.
    You can also have a look into your services file on your machine. If you have a windows machine then the file exists e.g. here C:\WINDOWS\system32\drivers\etc\services
    In this file you should search a entry like sapms<SAP System ID>.

  • Error While Debugging the Application

    Hello,
    I am developing applications using WebDynpro  for JAVA.
    I am using NWDI 7.0.
    I am getting an error while debugging the application. When I click on debug mode in debug perspective, I am getting error message as :
    "Failed to connect to remote VM. Connection refused"
    Could any one of you help in resolving this error?
    Thanks and regards,
    Pradnya

    Hi,
    I think NWDI has nothing to do with debugging the application.
    Probably you will get some answers in WebDynpro java forum

  • ERROR while debugging a SELECT..ENDSELECT

    Hello All,
    We get an error while we go into the select..endselect loop during debugging. Because of this if we try to do some research on existing program with Select-endselect..it fails in the second pass of this loop.
    This problem was not there earlier, but after we upgraded from 4.6 to 4.7 this problem is bugging us..every day. Does any one have a clue why ?
    Thanks!!
    Regards,
    Vishal

    Hi,
      debugging a SELECT...ENDSELECT statements brings to a LUW commit work if no other work processes are available for debug.
    See OSS notes 675, 2104.
    From OSS note 675 **********************************
    Cause and prerequisites
    Chain of causes:
          1. There is a statement in one of the Select loops, that leads to a database Commit (or Rollback).
          2. A database Commit causes the database to lose the cursor.
          3. The system cannot automatically continue within Select loop after loss of cursor.
    Following statements lead to a database Commit:
        * All statements that cause a change of screen (CALL SCREEN, CALL DIALOG, CALL TRANSACTION, SUBMIT, I/W-Message)
        * BREAK-POINT/ Debugging
          . if no debug process free
          . always after regeneration (in order to release generation lock).
        * WAIT Here a work process is released and a Commit is executed.
        * COMMIT WORK/ROLLBACK WORK
    From OSS note 2104 **********************************
    Solution
    The "COMMITWORK" message appears in the ABAP debugger when programs
    orscreensrequireregeneration,or when not enough free capacity
    is available inthesystem (or else the debugger blocks a system
    process).
    Normallyonly one work process is released for debugging. This
    isgenerally insufficient ina developmentsystem, as processes
    can be blocked for other reasonstoo(background processing,
    CPI-C connections,andso on).
    The number of work processes made available for debugging can
    be configured using the profileparameter
                      rdisp/wpdbug_max_no
    Forexample:
                    rdisp/wpdbug_max_no = 10
    setsthe maximum number of work processes made available for
    debuggingto 10. It may be necessary to generally increase the
    numberofwork processesatthis time (parameter rdisp/wp_no_dia).
    In all other known cases, an error in the application program is
    involved.
    Regards, Manuel

    Thanks and regards

    Hi
    apparently u r using but this item type is considered is considered obsolete item no longer supported in forms 10.
    You would need to use CLIENT_OLE in the webutil package to launch e.g. Word and etc.
    It is documented in oracle regarding Migrating Client-Server Applications to the Web
    Instead, use JavaBeans to duplicate functionality in the user interface. Any other Microsoft Windows user interface dependencies should also be replaced with JavaBeans. You can also use WebUtil to restore some of these functions.
    Hope this helps...

    This NolifeParser is some third party package, right? Do you have the source, I mean do you have in your project the file NolifeParser.java?

        NolifeParser parser = new NolifeParser(scanner);hi all,
    I am debugging a java program in Eclipse 3.2.1 in debug perspective.
    When I'm just running the program it's fine. But when I'm launching the debugger, and trying to step into the NoLifeParser() it stops and shows me the error message like this:
    ClassLoader.class
    Source not found
    The source attachment does not contain the source for the ClassLoader.class
    You can change the source attachment by clicking Change Attached Source below:
    BUTTON
    and then the source code for ClassLoader class.
    Please help, I'm struggling =(
    Thanks in advance,....!!

  • How to handle the error handling..its urgent

    hi guys...
    how to handle the Exception using jsf. for example...in java program we try to connect the server...if server not connect then the exception occur like java.net.ConnectException.. i have to handle exception using jsf and display related error page...plz give me ur valuable words..its need is very urgent..
    advance thanx and with regards
    DJ

    Hi,
    1. create a new error bundle (myErrMsg) // copy from javax/faces/Messages.properties in jsf-impl.jar
    2. declare this bundle in your faces-config
    <application>
    <message-bundle>bundle.MyErrMsg</message-bundle>
    <locale-config>
    <default-locale>en</default-locale>
    <supported-locale>de</supported-locale>
    <supported-locale>fr</supported-locale>
    </locale-config>
    </application>
    3. handle the Exception in your backing bean
    ResourceBundle bdle = ResourceBundle.getBundle("bundle.MyErrMsg",this.getLocale());
    context.addMessage(clientId, new FacesMessage(severity, bdle.getString(key), null));
    4. add the tag messages in your jsp
    <h:messages layout="table" errorClass="TextError" infoClass="Text"/>

  • Error while registering Provider Urgent..

    The following error occurred during the call to Web provider: Unable to initialize new provider instance: oracle.portal.provider.v1.ProviderException: Unable to acces method setDataClass (WWC-43147)
    null

    This message indicates that the method setDataClass(String class) cannot be found while processing your provider.xml.
    verify that the containing element (a personalization manager?) does in fact contain the method.
    Have you tried running the provider in test mode (just enter the URL of the provider in your browser. If you are using JPDK 1.4 or later, it will help you debug your provider.xml).
