Tutorial.class  not found

My internet explorer is not able to show java applet and just shows grey box instead.I have put all required classes in public_html directory and call them from index.html.On going to this URL from the web browser
it shows everything else except the button(java applet) which is supposed to be clicked to pop up another java applet.On putting cursor on top of that grey box ,it displays at the bottom of browser class tutorial not found. I don't know what to do i need to make this work ASAP....please help!!!!

Hi,
the class gets loaded in IE when i click on option java(Sun) 1.4.2........[requires restart] in Advanced section of internet options--> tools-->Advanced -->java(Sun).I use windows 2000 and everything works fine. But when i try to load same applet from other browsers like windows XP/98 it doesn't work.When i checked internet options--> tools-->Advanced --> There is no option like java(Sun) 1.4.2....[requires restart].
What surprises me is that i can open most of the java applets which are already on the net on some sites.How i am able to see those applets on windows XP/98? can u help....Only in these browsers i get message at the bottom of browser that load:class XXXX not found.

  • J2EE tutorial - class not found....

    Hi,
    I'm working my way throught the sun J2ee tutorial. I've just tried to create a mini JSP app of my own with an imported JAR file from one of the tutorial examples. This JAR file can be used ok from the tutorial JSP files but not from mine, I get:
    Class database.BookDB not found.
    bookDB = (database.BookDB) java.beans.Beans.instantiate(this.getClass().getClassLoader(), "database.BookDB");class not found
    All the fields and settings for my app in the deploytool match those on of the working example.
    Has anybody got any suggestions or a list of things I can check?
    Cheers for any help offered :)

    The JAR file should be present in the classpath. Make sure you are doing this.

  • 11g Tutorial "classes" not found

    I was going through the setup steps to install the "Oracle ADF: Build a Fusion Web Application" tutorial found under Turoials this site and when I run the "build.xml" ant file an error is display that says:
    BUILD FAILED
    C:\download\jdeveloper\FOD_11\Infrastructure\Ant\build.xml:38: destination directory "C:\download\jdeveloper\FOD_11\Infrastructure\Ant\classes" does not exist or is not a directory
    The directory "C:\download\jdeveloper\FOD_11" is where I unziped the FOD_11.zip file to. Under the "Infrastructure\Ant" direcortory there is not a "classes" directory. How is that created? It is not in the zip file either, does it have to be built, if so how?

  • Class not found error for COM.ibm.db2.jdbc.app.DB2Driver

    i have written this code:
    import java.io.*;
    import java.sql.*;
    public class tryjdbc
    {  public static void main (String args[])
    {  try
    {  Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");  }
    catch (java.lang.ClassNotFoundException e)
    {  System.out.print(e.getMessage());  }
    and once i try to run it, it gives out a class not found exception error.
    I haven't changed anything with the classpath since I don't think the problem is with the classpath. I have read in the IBM Developer Kit for Java documentaton that the AS/400 Developer Kit for Java automatically adds the db2_class.jar file to the classpath. So why do I get a class not found exception error?

    I was using Web Spehere 4.0.3 and trying to connect to a database on DB2 7.2. I was just following a tutorial and trying to get a handle on Web Sphere. I am running all of these on a Windows 2000 Operating System. Here are some of my observations :
    a. db2java.zip packaged under %DB2ROOT%\SQLLIB\JAVA, does not work.
    b. CLASSPATH needs to be set to %DB2ROOT%\sqllib\java12\db2java.zip
    c. Include this as one of the packages in the package defined in
    WebSphere, using the Java Perspective.
    d. Ensure that case sensitivity is respected. All though the package
    shows up as COM.ibm.db2.jdbc.app.DB2Driver, for some reason, it
    will only accept com.ibm.db2.jdbc.app.DB2Driver.
    With these settings, I was able to connect to a db2 database.
    I am a little puzzled on the following. I did not include java.io package, but still it could print the messages. Did anybody have a similar experience
    Thanks for this posting.

  • Class Not Found Exception After Connecting From a JDeveloper

    Hi,
    I am following the tutorial on SOA and started to experience problems in deployments (all but the console, including em) after the connection to the remote weblogic (10.3.5) from JDeveloper. I would know if the connection modifies the WLS environment. Unfortunately I did not note the message before wiping the setup, but found many entries on Google referring to some ADF library. I followed the suggestion to apply the adf runtime to the WLS install but this not helped.
    By the way, I would just understand if the remote connection from a JDeveloper adds some configuration which is then eventually not found in the target WLS.
    Thanks

    Can you check the log files of soa_server1, which are located in the <domain-home>/servers/<server-name>/logs.
    There are probably some occurences of class not found exceptions.
    When you are using the node manager to start your environment you have to make sure that StartScriptEnabled is set
    to true in the nodemanager.properties file (located in the directory: <wl-home>/common/nodemanager
    In the section "Starting the SOA environment" here - http://middlewaremagic.com/weblogic/?p=6040

  • Class not found while using rmic.exe

    This is my first RMI program, so bear with me.
    After compiling both my object interface class file and my object implementation file (both with no errors), i move on to create the stubs/skeletons (or whatever they are called). After executing rmic MyObjImplementation, i get an error saying the following - "error: Class InputDeviceImpl.class not found."
    I dont understand this, the .class file is indeed in the directory, and i know the rmic.exe sees it because i have tried to type "rmic *.class" and it gives the same error for every .class file in the directory.
    whats going on?
    -joey

    well i figured out to compile the program, but i still dont understand what happened. I read the tutorial on this website, and it told me to start the rmi registry first. So does this mean that i have to do this each and everytime?

    RT.JAR Files as mentioned in the Error log is not in the Directory ( you can verify)
    Usually rt.jar is in

  • For weeks I have been viewing a doggy day care via their web cam.  This weekend I upgraded to Lion and have been unable to view the center since.  I get an error message for java webcam class not found.  All of my software is up to date--suggestions?

    For weeks I have been viewing a doggy day care center via their web cam.  This weekend I upgraded to Lion and have been unable to view the center.  I get an error message for Java plug-in 1.6.0_29 ....webcam class not found.  Any suggestions on how to fix this?

    Sorry, don't know what else to suggest unless there's a URL to the problem stream that someone here can try. Otherwise we can't test it to try and determine what might be wrong.
    BTW, make sure they're testing it with a Mac, not with a Windows system. If they test only with Windows, what they say is or is not working doesn't mean much.

  • "Java Class not found in classpath" Error in DESIGNER

    Hello All,
    I'm trying to connect in Designer using a JDBC connection to MS SQL Server 2008.  As per the instructions, I updated my jdbc.sbo file with the path to the existing two JAR files.  However, I still get the following error when I try and connect in Designer:  "Java Class not found in classpath : C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\jdbc\Drivers\sqlsrv".  Of course, this error includes the drive path with the location to my JAR files.  Any help in resolving this nagging issue is very GREATLY appreciated.  Also, if anyone needs it I can post a copy of the jdbc.sbo file to this thread.
    Thank you,
    Pankaj

    Stratos,
    Your suggestion didn't help.  I tried to connect after restarting my machine and I still get the error.  And, I've also tried adding a connection to MS SQL Server 2005 using this JDBC driver, and that didn't help either.  Any other suggestions?  Would it help to see my "jdbc.sbo" file?  Thanks again for your and everyone else's help, and I look forward to your reply.
    Regards,

    I have also tried to open on 6.1 with similar results.
    I am familiar with lookout, however I have taken this project over so I am not sure what I need to do from here.

    There are two object (DirectLogic and Meter) that are not present on the amchine you are moving the process to.   If the same version of Lookout, you might be able to just copy the cbx files.

  • Class not found in applet using 2 jar files

    I have an applet which has been working for years as a stand alone or connecting directly to a derby database on my home server. I have just changed it to connect to MySQL on my ISP server via AJAX and PHP.
    I am now getting a class not found error in my browser, probably because I'm stuffing up the class path.
    The HTML I am using to call the applet is:
    <applet code="AMJApp.class"
    codebase="http://www.interactived.com/JMTalpha"
    archive="AMJ014.jar,plugin.jar"
    width="500"height="500"
    MAYSCRIPT style="border-width:0;"
    name="jsap" id="jsap"></applet>The AMJ014.jar contains the applet and supporting class files.
    The error message is strange to me because it refers to a class I noticed on another web page but which has nothing to do with my applet. Anyway, the message in full is:
    load: class NervousText.class not found.
    java.lang.ClassNotFoundException: NervousText.class
