  • Java.lang.OutOfMemoryError during message monitoring in RWB

    Java Engine Problem during message monitoring in runtime workbench!!  
    Posted: Nov 12, 2007 2:13 AM     Edit      E-mail this message      Reply 
    Hi,
    Our integrating processes are processing successfully.
    But there is a problem during message monitoring.
    When I use message monitoring in RWB,
    Integration Engine monitoring has no problem.
    But there is a problem during displaying adapter engine monitoring.
    The message is "java.lang.OutOfMemoryError: Java heap space".
    So I cannot see any adapter engine message.
    Actually same error occurred 3 weeks ago.
    At that time, we solved the problem with restarting java service.
    Does anyone know about this appearance?
    And is there any other solution about this problem??
    Thank you.

    Hi,
    As per the error analysis, it seems that the java heap space is low. So need to increase the heap size.
    1. Go to the C:\SAP\JP1\JC00\j2ee\configtool folder
    2. Start configtool.bat
    3. Go to cluster-data -> template - template_javaee -> instance - IDxxxxx
    4. Go to the VM Parameters tab and edit the maxHeapSize property
    5. Save and restart the system.
    I hope this will solve the problem.

  • Sender  Mail Adapter - java.lang.NullPointerException in CC monitoring

    hi,
    I configured my Sender Mail Adapter correctly.
    I have the correct POP URL, authentication. I'm not using PayloadSwapBean right now.
    I can't get rid of the exception inside my Channel monitoring.
    exception caught during processing mail message; java.lang.NullPointerException
    does anyone know why?
    I've been told the POP account has emails already.
    I will try to create an outlook account for this POP e-mail account in the mean time to see the e-mails.
    Thank you

    thanks aaron.
    I don't see the folder ./SYS/../j2ee/...
    will it be under another folder?  I don't see a trace log folder either.
    I think the problem might be in the Module tab.
    I tried.
    AF_Modules/PayloadSwapBean
    localejbs/AF_Modules/PayloadSwapBean
    /localejbs/AF_Modules/PayloadSwapBean
    sap.com/com.sap.aii.adapter.mail.app/XIMailAdapterBean
    localejbs/sap.com/com.sap.aii.adapter.mail.app/XIMailAdapterBean
    /localejbs/sap.com/com.sap.aii.adapter.mail.app/XIMailAdapterBean
    they all produce the same error. I wonder if these Beans actually exist.
    I think we might have to reinstall this Mail Adapter altogether.
    Or maybe it's really the connection to the Mail Server. But would it display this kind of message.
    This is what I'm looking at.
    Also, i had to use this URL
    pop://server:995/
    (995 is using SSL and it is the default port).  When I use this, I see the Java Null Pointer Exception a lot less frequently. Weird.

  • Getting "java.lang.NullPointerException" error message when trying to run an OATS OpenScript file from Eclipse to Create a record in Oracle EBS

    Hello,
    I'm trying to run a simple OpenScript script in Eclipse that creates a record (a Supplier in this case) in Oracle E-Business Suite. So I copied the the script file from OpenScript and created it as a Class in Eclipse.  Then I created a main class to call the methods within the script class but no matter what method I call (initialize, run or finalize) I'm getting the java.lang.NullPointerException message. The error doesn't seem to be related with any specific line in the script but with the way that I'm calling it.
    Should I call the OpenScript class from my main class in a different way? (see my examples below)
    BTW, all external .jar files coming with OATS have been added to my project in Eclipse.
    1) Here's the main class I created to call the OpenScript method (Eclipse auto-corrected my main class adding a Try and Catch around the method call):
    public class Test {
        public static void main(String[] args) {
            nvscript nvs = new nvscript();
            try {
                nvs.initialize();
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
    2) Here's the script from OpenScript (the actual script has more steps but I'm just using the first one for a proof of concept):
    import oracle.oats.scripting.modules.basic.api.*;

  • Java.Lang.nullpointerexception issue only isolated to a repository on the job server

    I am having the
    "Java.Lang.nullpointerexception" error message issue only isolated to a repository on the job server.
    This error message appearing when i try to execute or create a new schedule for a job on mgmt console.
    I have few other repositories in the same server, with those repositories i am not having any issues, in terms of executing a job or creating a new schedule.
    Does any one had the similar issue, and know how to resolve it.
    Thanks a lot for the helpful info.

    Hello George / Viacheslav, thks to both for responding.
    BODS is based on 4.0 never was migrated from 3.2

    THis error message started just two months ago, since then it is not allowing any new jobs to be executed or creating any new schedules.
    But all prior jobs are running fine no issues.
    FRom designer i am able to execute with no problem, This issue is only happening on Mgmt console and only in this repository.

    u2022SRM is sending around 1000 messages through background job and around 995 or 996 messages are being processed successfully and showing the proper XML payload as well in RWB. But 4-5 messages are getting failed in XI RWB for u2018java.lang.NullPointerExceptionu2019. For these failed messages we are not able to see the XML payload as well in XI RWB while these messages are showing successful status in MONI in SRM and XI and we are able to see the payload as well in MONI. The webservice is restarting and trying to send the payload three times in RWB, but it is getting the same Nullexception error.
    04.11.2011 16:45:49.715 Success Delivering to channel: CC_B2B_HUBSPAN_RCV

    u2022If we are resending the failed message from XI RWB, it is getting failed again with the same error. On the other hand if we are initiating the message again from SRM to Hubspan for the same PO, it is getting processed successfully in RWB but still not showing XML payload in RWB.
    u2022If we are getting the payload from XI MONI for the failed message and doing a test with component monitoring in RWB, it is working fine.
    Please help me to solve this issue.
    Thanks
    Sumit

    Hi Sumit,
    From my experience, when you transfer  SAP POs through PI to external webservice, there should be some validation happens at the webservice layer of the target system before the web service passes the original information to  their application layer. The validation can be anything like checking the Vendor address, Checking the correctness of the order ...etc etc . So i would suggest to ask your external web service folks to check if they have any validation in place before they pass the data to their application layer.
    As you said only some POs/XMLs are failing, i strongly feel that this could be the issue.
    Please note if you receive response code other than 200 from webservice, SOAP adapter treats that as error and send the same message back to AE.
    Normally webservices won't send 200 code for any validation error
    PS: you can still try to use XMLSpy to post the failed message to the web service to know the exact cause.

  • File Module Generation: Error: java.lang.NullPointerException in RWB.

    Hello XI Xpert's,
    I am following below SDN blog to generate file module...
    https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/da5675d1-0301-0010-9584-f6cb18c04805
    I have done all steps as mentioned using NWDS. We have sucessfully deployed same on J2EE engine using SDM. SDM logs shows that it is sucessfully deployed.
    I have configured Sender File adapter to call my customised module.( Called before standard file module).
    But when I checked in RWB, its gives me error :
    Sender Adapter v2703 for Party '', Service 'BS_DEV_XI_401_NA':

    If I do not put any file in respective folder status of Sender Communication channel shows as green...as soon as put any file in folder its getting red with above mention error.
    I have gone thru almost all SDN blogs/thread ..I also tried to debug code as mentioned in thread..Error in Module Processing- java.lang.NullPointerException
    But unfortunately it never goes to that point...hence never updates Log.
    In audit log I am getting same message..

    But could not find my Custom Message... There is any way by which I can check if its calling my Custom Module itself?
    There is any setting / parameters which we need to do on J2EE engine in order to activate call to custome module?
    Any help would be really appreciated.
    Nilesh

    It is strange, but in that document of yours it never says anything about the JNDI name in the ejb-j2ee-engine.xml file.
    Check this doc here:
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/3bdc14e1-0901-0010-b5a9-a01e29d75a6a
    According to it, if you properly configure the ejb-j2ee-engine.xml file, then you'd call your module using "localejbs/<JNDIName>".
    Regards,
    Henrique.

  • Java.lang.NullPointerException ADF_FACES-60097 message ***WITH SOLUTION***

    Hi Everyone:
    We are on JDeveloper 11.1.2 & JHeadstart 11.1.2. When testing an application that had previously been written in 10g and migrated to 11g, then migrated again to 11.1.2 because our database has logical composite keys, we have found that if we manually inputted an invalid value into the inputtext box of a primary key that has an LOV on it, the following message came up.
    "java.lang.NullPointerException
    ADF_FACES-60097:For more information, please see the server's error log for an entry beginning with: ADF_FACES-60096:Server Exception during PPR, #"
    with a random number displayed. We wondered where the java.lang.NullPointerException was coming from and then on a whim, tried to see if it couldn't find the error messages that were previously found in ApplicationResources_en.properties file in 10g. So I manually copied all of the error messages found in the ApplicationResources_en.properties file in 10g, into the end of the ApplicationResources_en.properties file on 11.1.2. There were only about 100+ messages in the 11g version of the ApplicationResources_en.properties file when there were almost 3,000+ messages in the 10g version of the ApplicationResources_en.properties. I then re-ran the job, and the proper error message comes out with no java.lang.NullPointerException message when I input an invalid value into the primary key (+Artransactioncode with this TransCode does not exist).+
    Is this a known issue when converting from 10g to 11g?

    Hi Everyone:
               I have done some further testing.  We are using a re-usable Business Components .jar file to access our entities.  We import the .jar file into the project and create the ViewObjects and ViewLinks from that .jar file.
                It APPEARS that a test case using the HRSchema and using the Entities & Associates generates the constraint error messages, but when I use the .jar file of re-usable business components imported into the project, those constraint error messages are not created in the ApplicationResources_en.properties file.  I have created two testcases as well as the re-usable .jar file that I can send to you to show what I mean. 
                This behaviour seems to have shown up in 11.1.2 as there was no problem before this.
                 Please let me know where you'd like me to upload the testcases.
                 Thank you.

  • Com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.lang.NullPointerException in sap pi

    Hi all,
    I am working on SAP PI 7.3.1 SP09. Currently we have interfaces which uses 50200 port. I have created a http destination from nwa pointing to https://....url. So all of a sudden all the interfaces went to error state. After debugging i found that the port 50200 is replaced with 50201which is https port. After changing the port to initial value ie., 50200 all interfaces are working fine except the one which were pointing to https url and they are showing the following error description.

    HI,
    Thank you for your hint. Maybe I just forgot to mention one important fact. We have second SAP Netweaver PI 7.1 which is completely our system. The first one I mentioned in first message is the customer's one. The one we have extra is also connected to MAXIMO and GIS. Settings of this interface is completely same among one thing:
    Patch level of XIAF:
    1. customers SAP PI level is
    Adapter Common Library Version: 1.7.1007.20081105173106.0000, NW07_07_REL (2008-11-07T17:29:47+0000)
    Adapter Application Version: 1.7.1007.20081105173106.0000, NW07_07_REL (2008-11-07T17:30:00+0000)
    2. our SAP PI level is
    Adapter Common Library Version: 1.7.1008.20100215155230.0000, NW07_08_REL (2010-02-15T17:19:21+0000)
    Adapter Application Version: 1.7.1008.20100215155230.0000, NW07_08_REL (2010-02-15T17:19:31+0000)
    Both of them has Axis Version: Apache Axis version: 1.4 Built on Apr 22, 2006 (06:55:48 PDT)
    Also important to mention is fact that same problem happened in our SAP PI, but we implemented last patch of XIAF and it has suddenly started to work. I have suspicion it is somehow connected to this patch. Btw. this patch contains a lot of notes regarding  AXIS framework (i.e. 1435998, 1150375, 1048268), so obviously some bugs of the AXIS adapter has been resolved by this patch.
    What do you think ?
    Thanks

  • When trying to launch a Java preferences get this message:  Cannot launch Java application A static initializer of the main class threw an exception: java.lang.NullPointerException"

    I have an IMac 10.5.8 and I am having problems with Java. I have tried todownload Java for Mac OS X 10.5 Update 4 and it looks as if it is doingsuccessfully, but I cannot see where it has put it and get this message when trying to launch Java preferences:
    Cannotlaunch Java application
    A static initializer of the main class threw an exception:java.lang.NullPointerException"
    Couldyou please help?

    Hmm, only way I know would be a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

    Just be sure to select Preserve Users & Settings.
