Cluster: lookup throw ClassNotFoundException when MyObject was bind

I have problem with lookup MyObject (whitch implements serializable) from InitialContext on cluster machine 1, when I bind it on machine 2.
Lookup throw:
binding java.lang.ClassNotFoundException: MyObject
java.lang.Class com.evermind.naming.ContextClassLoader.findClass(java.lang.String)
ContextClassLoader.java:456
second time lookup return object not found. On Machine where i bind object lookup work good.
With standard objects (String, HashMap,...) this bind an lookup work on both machines perfect.
Aplication is deployed as distributable, and i configured RMI replication.
Can you help me?
AppServer: OC4J 9.0.3
JDK: 1.3.1

I doubt you'll get much response on an Oracle specific question concerning naming in a clustered configuration.
This forum is concerned with Sun's J2EE 1.4 SDK and related technologies.
Perhaps you could post this question in an Oracle specific resource:

    Solved it on my own.
    The sso from Java->ABAP was OK
    I reconfigured the sso from ABAP->JAVA by creating new ABAP certificate and import it to the J2EE.

    I used to use the free version of Adobe Reader to convert my publisher files to pdf files. When I was making a booklet for our hockey team, it said I had to buy it. Now I bought it and it won't convert the files. I am ready to throw this computer out the window!! Can you tell me what is the problem? No it does not exceed 100 M. either.

    Adobe Reader never converted Publisher files to PDF, for free, never. I suspect you use to have the (paid for) Adobe Acrobat. Sometimes people have Acrobat (more than $300 worth) and install Adobe Reader over the top, losing that valuable software.
    That said, if you subscribed to PDF Pack it should do this conversion. What exactly happens now.

    Excel is throwing error when it click print : 'No printers are installed. To install a printer click the File tab, and then click Print. Click No Printers Installed, and then click Add Printer. Follow the instructions in the Add Printer dialog box'
    Word, and powerpoint application are working fine.  
    Environment :  Windows 7 64-bit, MS Office 2013 64-bit
    Steps to recreate
    (i)  Create new user account and add to any group ( do not log on using this
     account)
      (ii)  runas /user:<new user account>  <fullpath>\excel.exe

    Sorry for late reply i was not at work
    I have a default set excel is still throwing error. Interestingly winword , powerpoint and publisher are working fine. I am able to print from all office applications except Excel.
     Probably excel behaves differently from other office applications.
     Probably it is a bug in excel
    Workaround : Log on to a system once using newly created account then runas excel using this account then print works fine.
    It means something in user profile should be configure to run excel print operation. Could you please somebody help what I need to configure in user profile that makes print operation success?

  • [Windows] file.url throw error when application executable in root directory

    Here is the bugbase ticked: Bug#3940278 - [Windows] file.url throw error when application executable in root directory
    If you launch AIR application packaged as bundle from root directory and try to get url property of any file you get IllegalOperationError.
    No matter what file url property you try to get.
    It's a big problem when you distribute your application on CD disks or flash drive.
    I'd like to ask everyone affected by this issue to take a minute and vote for the following bug.
    Thanks.

    I checked all deployment descriptions and there are no references to t3://localhost:7001. Few months back, I had the complete clustering setup working on 2 machines and now when I deploy my application on same configuration, it fails with t3://localhost:7001 unreachable error. I created a new cluster configuration on one machine with 2 managed server and it deploys fine. Can not figure out what has changed ?

    there is a "Open class" button on the app, click the button, i use FileChooser to open any class file.
    i.e. open a class (assume it is not packaged)
    d:\dir\TheClass.class
    coding in StudyApp.java is:
    Class cls=Class.forName("TheClass");
    now a ClassNotFoundException throws when call Class.forName() above.
    it is easy to understand why throw the exception because i never tell where the class is. it is in directory
    d:\dir
    my question is: how to tell VM the directory.
    the directory d:\dir can not be applied to -classpath when run java.exe StudyApp, because the directory is random one at run-time.
    i tried to change System property (i.e. "java.class.path", 'user.dir" etc. none of them can fix the problem.
    thanks in advance for any help

    any ideas what is happening?
    thanks

    two clarification questions:
    (1) what version of the IDE are you using (can find info under help menu)
    (2) what kind of project is this?
    What I am looking for is whether or not you are openning a project created in one version of the IDE with another version. If you have recently upgraded your IDE you may consider starting with a clean userdir.

  • HT4623 When I was update ios6 for iPhone 4 , mail and application are hung , why ?

    When I was update iOS 6 for iPhone 4, mail and application are hung , why ? How I should do for that ?

    They don't let you downgrade.  You have to eat what Apple tells you to and think what they tell you to.  If you liked the older software better than tough ****.  You know what you should do??  You should throw away that garbage that Apple has sold you that they call a phone and get something by anyone else because no one else regulates what you get to do and say about your phone in such an extreme manner.  Not being mean to you friend.  Just know that as long as Apple is answering your questions that you will never get a definate answer and at best you will get something that you don't like but have to get used too.

  • My contacts vanished when I was manually adding them on my Ipad 2. I use outlook contacts when I sync on ITunes. How can I fix this problem?

    I'm having the same issue and I'm using outlook when synchronizing. However, I'm not sure if this is an Oultook vs. MobileMe deal. The thing is: I got my IPad 2, made sync with Itunes and got all contacts from my Outlook and when I was making few adjustments / updates to such contacts directly on my IPad 2 (without being connected to anywhere, the software crashed and the contacts simply VANISHED ! Please help me... I'm really concerned with that because now I have everything on my Outlook, but I gotta be able to update many contacts in events (for example, a meeting or a workshop) directly from my IPad, being away from my computer, and now I'm in total risk of simply losing them... I simply don't believe that a bug with totally affects the product reliability can't be simply solved!
    Thanks in advance for your help!

    Thanks for starting the thread clisfromSLC.
    I am facing the exact same problem with my brand new ipad2. The addition of a single contact post a successful sync, caused the app to crash. Restarting the app did not get the contacts back. Neither did restarting the ipad itself.
    I dont want to rely on the ipad now until I have a patch or OS update that corrects this issue. If I add several contacts and suddenly lose all of them, it's not something i really look forward to.
    Can someone please help? Thanks so much.

  • HT201272 When iTunes was upgraded to the lastest (11.0), many of of songs/music/audiobooks were deleted!  I tried syncing my phone to my computer to get them back, but many of those were deleted too!   How do I get my purchases back to play them???

    When iTunes was upgraded to the lastest (11.0), many of of songs/music/audiobooks were deleted!  I tried syncing my phone to my computer to get them back, but many of those were deleted too!   How do I get my purchases back to play them???
    It shows on iTunes SOME of my past purchases, but not all (looks like around 30-40% of purchases).    It shows on my apple id purchase history everything i have purchased; but in iTunes, some not all of these show up.    What does show up is kind of "greyed out", so NOTHING will actually play.   I have followed the steps in the iTunes support about how to redownload past purchases, but this dowsn't work, as the download button is also "greyed out". 
    I am extremly angry and upset about this issue.  Could someone please help / advise re how to fix????

    I'm hoping that this may be just a misunderstanding somewhere.
    Could you show an image showing these greyed out items?

  • TS1702 I downloaded from the Apps.store a game named 'Ninja Run'. When I was playing this game, I got out and then received a message,'"Do you want to buy 5 revivals for Rs.170/-?". When I clicked the "Buy"

    I downloaded from the Apps.store a game named,"Ninja Run". When I was plkaying the game, I got out and a message appeared, asking me whether I would like to buy 5 revivals for Rs.170/-. When I hit the,"Buy"button, I was asked to confirm my Credit card details. I confirmed it and was asked to enter the Security Code. When I did so,, a message appeared telling me that the Security Code was invalid and the purchase could not be completed. When I continued the game and got out again, the message appeared again asking me whether I wanted to buy. Thinking that my purchase was not completed, I again hit the,"Buy" button. Nothing happened. I continued the game and when I got out, I received the same message and obliged accordingly. This went on for three or more times. By this time,however I got confused and quit the game. All these things happened on 6th September 2013. The next day,I was shocked to see 5 receipts from the Apple Apps.store in the In Box of my email account,each for Rs.170/-
    totalling Rs850/. Worse still, when I played the game the next day and got out and asked for a revival, would you believe it, I was again asked whether I would like to buy 5 revivals for Rs.170/-.
    Thus,I ended up buying a game for Rs.850/- while the actual price is only Rs.170/-,and not even able to play the full game.
    Could anyone please tell me whether I can get a refund of Rs.680/-,the extra amount I  paid for this game.
    I will be much thankful to anyone who can guide me and help me claim the refund. Thank everyone.
