SevletContextImpl not serializable exception when one cluster is restarted.

Hello,
          I am using WLS 5.1 SP8 with apache plug-in and in-memory session
          replication. There is one proxy server and two cluster: A and B. I started
          cluster A and B together and each cluster would "see" each other. I shut
          down cluster A and my session will continue working fine on cluster B.
          However, when I restart cluster A, I get the the following stack trace from
          cluster B:

          I looked everywhere in our code and we don't store ServletContext object
          anywhere in the session level..Can someone give me some hints as to what the
          problem is?
          Thanks for your help in advance.
          Vincent
          

You probably have a non serializable object in your session.
          You can have only serializable data in the session.

    Hi Mark,
    I have seen your two posts and there are something you need to notice:
    Where the ClassNotFound exception you got? From deployment tool or
    application server kjs process?
    Of course, you need not to add supporting classes to each ejb jars or ears.
    1. If you use deployment tool to package your application, I'm sure you'll
    fail to resovle your classes without supporting classes added to jars.
    Please select Edit->Preference,in Classpath entry, enter the supporting
    classes(packaged to jar files) location. This should work.
    2. After deploy to ias, please edit the registry using kregedit which you
    described in your posts.
    Regards,
    Johnson
    "Mark Priest" <[email protected]> wrote in message
    news:9s6h33$[email protected]..
    When I deploy EJBs to the iPlanet app server I find that I need to include
    all supporting classes in each ejb jar file. According to the
    Administrator's manual I should be able to modify the kjs classpath bydoing
    the following:
    On Windows
    a.. Open iPlanet Registry Editor.
    (See About iPlanet Registry Editor)
    b.. Open the following key:
    SOFTWARE\iPlanet\Application Server\6.0\Java\
    c.. Modify the class path and restart the server for the change to take
    effect.
    However, when I add my supporting classes to a jar in this directory Istill
    get a class not found exception when I run the deployment tool.
    Adding the classes to each EJB jar is redundant and introduces lots of
    problems. How should I configure iPlanet so I only need to put my
    supporting classes in one place?
    Thanks,
    Mark

  • Class Not Found Exception when saving in Backend?

    Hello all,
    we are using JBOSS, Hibernate, Flex 3 and BlazeDS.
    I have added a class ProjectDocument and it is configured identically to an existing class PartDocument.
    I can successfully load the class in front  end, but the save of the class leads to the following exception.
    The jar is successfully compiled, and includes both PartDocument.class and ProjectDocument.class.
    Does anyone know why BlazeDS cannot find the class?
    regards and thanks

    Hi all,
    we found the problem.
    To read the class in flex we used:
    registerClassAlias("ProjectDocument", ProjectDocument);
    Then BlazeDS sent as class name just ProjectDocument and not the whole string.
    So do not register classes - if you have a class coming from JAva that Flex does not recognise because it is not used in the mxml, just create a dummy variable.
    Hope this helps someone else!

  • Java Does Not Throw Exception When Writing To Read-Only Files

    I have noticed that when I try to write to a read-only file in a window environment, Java does not throw an IOExcpetion, it just dosn't write to the file.
    I am writing an FTP server and here is the code:
         public static long copyStream(InputStream in, OutputStream out)throws IOException
              IOException exception = null;
              long copied = 0;
              try
                   byte buffer[] = new byte[1024];
                   int read;
                   while((read = in.read(buffer)) != -1)
                        out.write(buffer, 0, read);
                        copied += read;
              catch(IOException e)
                   //ensures that the streams are closed.
                   exception = e;
              try

    Read the stack trace from the bottom up. It's telling you that the error, or exception arose
    at ZipUtility.zip(ZipUtility.java:21)
    which is udZipUtility.zip();This line called the zip() method which threw an exception
    at ZipUtility.main(ZipUtility.java:31)
    which is FileOutputStream fos = new FileOutputStream(strTarget);What is the value of strTarget?"C:\\Users\\dojo\\Documents\\Programming\\compress"This is a folder, isn't it?
    Read the javadoc for public FileOutputStream(String name)
           throws FileNotFoundException
    If the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason then a FileNotFoundException is thrown.

  • My ipod classic has started making a mewing sound and all it does is scroll through the songs.  It will not play except when connected to my computer.  I tried resyncing and that did not work. How do I fix this problem?

    My ipod classic has started making a mewling sound and all it does is scroll through the songs.  It does not play on my Bose sound dock or through earbuds.  It will play when connected to the computer...but that makes it hard to take it on a walk with me   I thought it might be a synching problem so tried that--still doesn't work.  How do I fix this problem with out restoring it to the factory setting?  I do not want to lose all my music content as some of it I cannot replace easily.  Please help with suggestions and advice. Thanks.  Karen in GA

  • Class not found Exception when accessing database through java using ASP

    I am trying to access the database through ASP via java:
    the database is setup as a system database..
    the java class works fine if i try to run it as a stand alone.. but as soon as I run it through ASP.. it does not get passed the driver line.. is there anything in particular I need to do ?
    JAVA and ASP and the output code looks like as follows:
    java code looks like this:
    import java.sql.*;
    public class testDB{
    private Connection connection;
    private Statement statement;
    public static void main(String[] args){
    public String getDriver(){
    String x = "start of program ";     
    try{
              Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
              x = x + " Got Driver";
              connection = java.sql.DriverManager.getConnection("jdbc:odbc:database", "sunny", "jassal");
              x = x + " After connection statement";
              statement = connection.createStatement();
              x = x + " After statement statement";
              statement.execute("Insert into name (name, age) values ('hello', 33)");

              x = x + sqlex.toString() + " " ;
              x = x + sqlex.getLocalizedMessage();}
    return x;
    and the asp looks like this:

         response.write "after getting object"
         response.write javaobject.getDriver()

  • The Stop button does not show except when I'm customizing settings

    I have just upgraded from FF 3.6 to FF 8. The Stop button (X) does not appear between the Reload and Home buttons.
    However, if I right click the menu bar and select Customize... , the X appears as it should, then disappears again when I close the Customize... box.
    Thanks for your assistance. This may be tied to the other error I'm receiving:

    Thanks, SafeBrowser. Step 3 did the trick!

  • Ics download of iCloud invitations ends in a not found exception when sending to external accounts (e.g. gmail)

    When I send a calender event from my iCloud account to an external account (e.g. gmail), the recipient got the following error:
    When clicking "accept" in the invitation mail, a icloud.com website will open. The "download ics file" (to import the event) on this site results in a "not found" error page. This behavior is new since some days.
    Does anyone have a idea how this problem could be solved?
    Thank you!

    That's a solution to a different problem.
    The problem is that people are receiving invites to their email address.
    And then when they click the link in that email to download and open the ics file with the update,
    there's no download and you get an error message "iCloud can't find that page".
    This happens to me using apples own email infrastructure, and is not (AFAIK) connected to gmail at all.

    As far as the null desctiption is concerned - is is possible that there is no more input and readLine returns null?

  • My ipad sound is not working except when my head phone is connected

    Plz help my ipad sound is not working but is when I put headphone.the sound comes when I activate Siri but otherwise no sound comes from ipad. the volume button is not workin but it used to. The slider thing to increase volume in the task bar is halfly gone means that dot is not there to increase volume

    Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
    If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

  • IPad will not play movies when I try to restart them.

    I rented a couple movies prior to a buisness trip.  When I was sitting at the airport, I started one of the movies and watched while I was waiting on my plane. They called my plane so I turned on airplane mode, shut down my I pad, and got on the plane.  When I restarted my IPad on the plane,  it would not play the movie.   I could see the chapters, I could see the other movies I had rented and downloaded, but none of them would play.   I even tried to play one of my other downloads and it did not work. Is this because I was in Airplane mode?  I could play one of the movies I own that is on the IPad, just not the rentals.  Once I was home,  my IPad hooked back up to my wireless, and worked fine and I watched the rest of the movie.  Is there some issue why this is not working?  If I can't rent movies to watch on an airplane, I am going to be pretty bitter.
    Thanks in advance.

    First thing to try is a reboot of your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.
    You won't have to swipe anything on the screen to reboot the iPad. Hopefully this will correct the error.

    Hi. I'm getting connection to failed service errors or not serializable errors when I run a production sized load for my project.  I'm trying to generate 100,000 PDFs one at a time on each thread against the Output web service.  I'm running custom code that makes the Output web service call on individual thread.  I run up to 40 threads against my vertical cluster and occasionally I see a not serializable error or connection to failed service on my code.  Any ideas on what could be the cause of the errors?  Thank you for any insight you can provide.
    I'm running a WebLogic vertical cluster on one box.  1 admin server of WebLogic 9.2 MP3 with 10 managed WebLogic servers on the same physical box in a cluster.  I have enough RAM to support all these JVMs and the GDS is on the local drive on the box.
    Environment details:
    Software: Windows 2003 R2 SP2 (32-bit), WebLogic 9.2 MP3, Adobe LC 8.2.1 SP3 + QF 3.19, Oracle 10.2.0.4, BEA Jrockit 1.5.0_12 (32-bit)
    Hardware: 2 CPU 2.8GHz * 4 cores * Hyper-Threading = makes it look like 16 CPUs in Task Manager, Performance tab, 16 GB RAM, 50+ GB HD space free
    Error Message:
    + com.adobe.idp.dsc.DSCNotSerializableException: Not Serializable
    IVS Error Message that happens randomly when the errors are occurring.  I can resubmit the same IVS test where this error shows up on the managed WL instance and it :
    java.lang.IllegalStateException: Connection to failed service. in com.adobe.livecycle.formsservice.exception.RenderFormException, cause: java.lang.IllegalStateException: Connection to failed service. in com.adobe.livecycle.formsservice.exception.FormServerException
    Exception in Output Service
