Oc4j log file: many java.lan.NullPointerException in log file

I use oc4j 10.1.3 Developer Preview 4

I don't know if this is normal or not, but it makes me a little suspicious

  • Error in file-webservice- file (Error: java.lang.NullPointerException)

    Hi everybody,
    I have configured a file-webservice-file without BPM scenario...as explained by Bhavesh in the following thread:
    File - RFC - File without a BPM - Possible from SP 19.
    I have  used a soap adapter (for webservice) instead of rfc .My input file sends the date as request message and gets the sales order details from the webservice and then creates a file at my sender side.
    1 communication channel for sender file
    1 for receiver soap
    1 for receiver file

    What could be the reason for this error

    This only happens immediately after logon; once the user clicks on another tab in ESS, the error is never re-produced again until the user logs off and logs back on.

    EP 7, ESS 603 SP4 P3.
    This apparently is only happening for one specific user. I'm in the process of gathering information about their internet browser to determine if that's the cause.
    I did check the JCos and they all tested successfully.
    Thanks,

  • Error in file cc attemp to process file due  java.lang.NullPointerException

    there is an error in file communication channel with error information
    *Delivery of the message to the application using connection File_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: java.lang.NullPointerException
    .*please post ur views what might be reason for this type of errors.

    Thanks all for your valuable and quick responses.
    MY concern is that why it created 1 file 3 times.
    i checked the ICF that is green.
    THe interface works like this
    *the idoc is sent from the SAP system.
    *and is received by a BPM in XI
    BPM sends the file to a file receiver channel.
    *Encryption program picks the file and encryption is done
    *Again the file is sent by file sender channel to receiver.
    the receiver is supposed to get 3 files but it is getting 9 files.
    one file 3 times.
    Moreover file receiver channel shows error jave lang null pointer
    please send in your views so that the problem can be sorted out ........
    Thanks.

  • How to display a .exe file in java applets by avoiding the file downloadbox

    Hi sir,
    I know that in order to display a any file(or)program in java applets you need to use showDocument().Where you cannot use exec() in java applets.
    My problem is that when i use showDocument() to display .exe file.It is showing a file download dialog box.If we click & open only it is opening that .exe file.Here i want to open the .exe file without showing that file download dialog box in java applets.
    Since,i am undergoing a project which involves it,it is quite urgent.pls.do provide the exact code in java applet without showing that file download dialog box.If it can't be done pls. do provide any other possibilities in order to be displayed on the browser.Thank U.
    Regards,
    m.ananthu

    Hi!
    I think you it's better to write a server socket program
    in server and open a socket connection to server socket then
    send exe file content via connection.
    (I guess you know applets only have permission to open socket connection to their code base)
    Bye!

    It means that you were not authenticated (such that, did not have a valid http session instance) - before trying to service the request.
    authenticate first via the application, then try and access the DocServlet.

  • Java.lang.NullPointerException (OC4J 10.1.3.1 & JDeveloper 10.1.3.1)

    My project that ran perfectly under JDeveloper 9.0.5.2/OC4J 9.0.2 no loner runs under Jdeveloper 10.1.3.1/OC4J 10.1.3.1.
    The failure (java.lang.NullPointerException ) is in the following code snippet:
    =================================================
    Public String getString(String columnName) throws SQLException {
    return getResultSet().getString(columnName);
    =================================================
    columnName is being passed the same value in both environments.
    The JSP snippet that executes the above is:
    =================================================
    com.app.servlet.SQLDataSource detail =
    ((com.app.servlet.SQLDataSource)request.getAttribute("AcctList"));
    <td width="20%" class="tableRow">
    <a class="a4"><%= detail.getString("ACCT")%></a>
    </td>
    ==================================================
    AcctList is a text file that contains the following SQL code:
    ============
    select ACCT
    , VDESC
    from GL
    :WhereClause
    :OrderByClause
    ============
    :WhereClause & :OrderByClause are set in a calling "Filter" JSP filter page.
    All debug statements in my code indicate the the getResultSet is properly executed. Yet when the detail.getString("ACCT") is hit I receive the NullPointerException.
    Any clues?
    Remember, no code has changed between the 9.0.2 and 10.1.3.1 environments. They both hot the same database with the same JDBC drivers.
    TIA,
    Ed.

    Jan,
    The NullPointerException is pointed to:
    at oracle.jdbc.driver.ScrollableResultSet.findColumn(ScrollableResultSet.java:1308)
    at oracle.jdbc.driver.OracleResultSet.getString(OracleResultSet.java:1572)
    at oracle.jdbc.SQLDataSource.getString(SQLDataSource.java:388)
    at apps.AcctList._jspService(_AcctList.java:66)
    The code ( in "_AcctList.java") at line 66 reads:
    out.print(detail.getString"ACCT") );
    However, digging into my application log file I found that the following error happend at 10:52:46.0 (the above error occured at 10:52.50):

  • Urgent - java.lang.NullPointerException when deploying a WAR file

    Hello
    I am trying to deploy a WAR file on 9iAS rel 2 using the Enterprise Manager. On the web page, I provide the .war file along with application name and url mapping. When I click on deploy, i get an error back which just says java.lang.NullPointerException. There is no stack trace.
    Until now, I have been working on my own PC using tomcat, and the war file works fine in tomcat.
    I am presuming that there will be a log file where more information will be available, but I do not know where the log file is kept. The Oracle 9iAS is installed on Solaris.
    Any help with this would be greatly appreciated.
    Thanks.
    Jay

    Problem Solved
    The problem was the web.xml file which contained some elements that are only valid for servlet 2.4 (used on tomcat) but not on 2.2(used in oracle).

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

    Hello XI Xpert's,
    I am following below SDN blog to generate file module...

    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':

    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>".

    Henrique.

    hi,
        If you are loading a resource (property) file from a jar file you can use
    getResourceAsStream("com/test/test.properties").
        if the propery file is in outside of your jar file . you can use
    Property portalProps = new Property ();
    try {
                   FileInputStream fileInputStream = new FileInputStream("<FilePath + FileName>");
                   portalProps.load(fileInputStream);
                   fileInputStream.close();
              } catch (IOException e) {
                   //Log the error

    Did your C:\Lighthammer\Security\userdata\IlluminatorUsers.xml or other files in this directory get corrupted somehow?
    If you've rebooted the box or bounced the ServletExec-xMII service, do you see anything in the SYSTEM level messages that are forced during the initialization sequence in either the Lighthammer General log or the LHSecurity General log that would give any indications to the problem?
