I have tried uninstalling, reinstalling, restarting IE etc, tried removed the sun folder from application data, none of which has not helped.
IE version 7.0.5730.11
How can I fix this?
Thanks

This line from your error next could require control for the version in the "java control panel" of the jre(s).
network: Connecting http://www.cmol.nbi.dk/models/epitrans/transcript.class with proxy=HTTP @ <REMOVED>
note the proxy= and look in Network Settings in the *"java control panel"* (not the output panel).

Load:Class * not found - in portal

In the webgui /portal a link is provided.
when you click the link , which is mapped with the transaction
code of the ABAP program. gets displayed.
THis program is used to download PO into the File
server.
so File output path is given.
The user uses F4 help to select the directory / filename as well
In the bottom we are getting a messge
load: class FileName not found
and load: class Directory Select not found
I use cl_gui_frontend_services=> directory_browse
and kd_get_filename_on_f4.
wat might be the problem for this?
Give me your valuable suggestions
This is urgent.

Hi,
the abap code you use, uses java for getting a filename and for directory browsing. So first of all you have to check,
if java is activated in your browser. Second, you have to test the frontend services in webgui with transaction se37, ws_query, enter "cd" into field query and executer this. Then you will get a security popup, which you have to accept. If all runs ok,
you will get the current home directory as result. If you get a java exception again, you have to check the network configuration
in the java control. It should be the same, as in the browser. If this does not help, try to request the applet ws.jar from the mimerepository .../sap/its/mimes/webgui/2002/applets/ws.jar
directly. Do you get the security dialog? The error you wrote above means, that the java applet ws.jar could not be loaded.
Is this an inhouse problem? external or integrated IITS. Which browser, which java version?
Regards,
Ralf

Load: class not found error with sdk 1.4.1 demos

I have read through a ton of messages regarding this problem with Internet Explorer 6. The only one I saw that had a work around was to compile with javac -target 1.1 <filename>
This kind of makes having 1.4 moot doesn't it? Has anyone else figured out anything about this error? I get it just from running the demos or a hello world applet with IE6. No problems with Netscape or the appletviewer.
Thanks in advance...
happy developing.

Have you configure IE6 to use the plug-in?
What is the HTML code like? What is the exact error message (i.e. what is the name of the class it says it did not found)?

Applet help, class not found?

hi all ! This is the first time I try a applet.
I have my applet declared in my JSP
<APPLET CODE = "AppletViewer.class" ARCHIVE = "MedPro.jar" WIDTH = "600" HEIGHT = "400">
/*creating space for better reading of the code*/ AppletViewer.class is part of a package called beans, and MedPro.jar is the jar generated when building the whole app.
Im getting in the applet "viewer" something like:
java.lang.ClassNotFoundException: AppletViewer.class
     at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
     at java.lang.ClassLoader.loadClass(Unknown Source)
Caused by: java.io.IOException: open HTTP connection failed:https://localhost:8443/MedPro/servlet/AppletViewer/class.class
Im using SSL to make the app secure, but what I dont get is why its not finding the class, isnt that independant from the connection? Plus the applet code is not asking for any connection atm. Im just trying to load it.
Any help is appreciated.
Thanks!

well what Im trying to do is to implement jasper reports in a viewer. So for that Im using
public class AppletViewer extends javax.swing.JApplet {
    private javax.swing.JPanel pnlMain;
    public AppletViewer()
    throws ClassNotFoundException
        initComponents();
         private void initComponents() {//GEN-BEGIN:initComponents
          pnlMain = new javax.swing.JPanel();
          pnlMain.setLayout(new java.awt.BorderLayout());
          getContentPane().add(pnlMain, java.awt.BorderLayout.CENTER);
     }//GEN-END:initComponents
        public void init()
    public void ViewReport(String jasperFileName) throws net.sf.jasperreports.engine.JRException,javax.naming.NamingException,java.sql.SQLException,
            java.net.MalformedURLException
               /* HashMap hm = null;
                 InitialContext ctx = new InitialContext();
                 DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/MedPro");
                 Connection conexion = ds.getConnection();
                // Create arguments
                // Map params = new HashMap();
                hm = new HashMap();
                // Generate jasper print
                //JasperPrint jasperPrint = (JasperPrint)JRLoader.loadObject(new URL(getCodeBase(), "../MedPro/Reportes/"));
                JasperPrint jasperPrint = (JasperPrint) JasperFillManager.fillReport(jasperFileName, hm, conexion);
      // JasperPrint jasperPrint = (JasperPrint)JRLoader.loadObject(jasperFileName);
       JRViewer viewer = new JRViewer(jasperPrint);
        this.pnlMain.add(viewer, BorderLayout.CENTER);
    }That class is part of a package called beans in a project called Medpro wich is compiled as a .WAR archive since its a webapp. The examples show a jar file instead wich is for libraries... so Im confused there. There is no documentation about it :(
I still get the error
java.lang.ClassNotFoundException: beans.AppletViewer.class I have tried everything, still nothing
Thanks for any help you guys can give me

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.

Class Not Found Exception - applet won't run anywhere outside of IDE

I have an applet that runs perfectly in the netbeans IDE, but won't run from command prompt (I'm using windows) or from a browser. I've been banging my head against the wall for a few days on this one. Here's the HTML I'm using:
<applet width="400" height="525" code="musicapplet.class" archive="crypticgraffiti.jar">
<param name="bgcolor" value="ffffff"> <param name="fontcolor" value="000000">
</param> </param> Your browser is not Java enabled. </applet>
Here is the structure of the jar file's contents:
META-INF/
META-INF/MANIFEST.MF
com/
com/crypticgraffiti/
com/crypticgraffiti/music/musicapplet
com/crypticgraffiti/music/GetNotes.class
com/crypticgraffiti/music/InstList.class

com/crypticgraffiti/music/MusicCreator.class
com/crypticgraffiti/music/OctaveTransformer.class
com/crypticgraffiti/music/Phrase.class
musicapplet/MusicApplet$playerThread.class
musicapplet/MusicApplet.class
(Musicapplet.class is the main class)
When I attempt to run from command prompt, I get:
"Error: Could not find or load main class crypticgraffiti.MusicApplet"
When I attempt to load via html:
"basic: load: class musicapplet.class not found.
load: class musicapplet.class not found.
java.lang.ClassNotFoundException: musicapplet.class
     at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)

     at java.lang.Thread.run(Unknown Source)
Exception: java.lang.ClassNotFoundException: musicapplet.class
security: Accessing keys and certificate in Mozilla user profile: null"
I have tried every possible variation for the 'code' element of the applet tag (package.mainclass.class, mainclass, mainclass.class, etc). I have also tried compiling with JDK 1.6 and this didn't change anything. I've tried clearing out the cache of temporary files using the java control panel settings, and have verified that my browser can run other applets using JRE 6 and 7.
I've tried some different ways of distributing the applet, also: putting all the class files in the folder with the html file, putting the classes in a source folder in the same folder as the html file, and finally putting a jar in the same folder as the html file (which really seems the simplest).
Any help at all would be most appreciated! This applet is a very cool and original music creating app that draws heavily on the JFugue API. It's a shame that I can't get it online for people to play with!

(Musicapplet.class is the main class)
Please note that class names are case sensitive so "MusicApplet" is not same as "Musicapplet" or "musicapplet". Your applet tag should have fully qualified class name (without quotes) and should look like this:
<applet width=400 height=525 code=musicapplet.MusicApplet archive="crypticgraffiti.jar">
</applet>
The JAR should be in the same directory as your HTML file. While launching from command line, you can also check if your JAR file is getting included in classpath.
Thanks,

Class not found. Or: THERE'S NO SUCH THING AS APPLETS

Okay, the problem I�m having seems to be somewhat widespread judging from the forum achieves, but I wasn�t able to find any answers that worked for me. So forgive me if I�m treading old ground, but asking explicitly is my one last attempt to learn what�s going on.
The problem is the �load: class <someclass.class> not found� gray screen whenever I try to view an applet. Now, looking around online, there are a few applets that I�ve been able to access, and many I haven�t; I�m not certain what causes some to work fine and others to gray screen, but there doesn�t seem to be a pattern to it other than the fact that if I can or can�t view one applet at a site, the same is generally true for all the other applets there as well.
Now, as for local applets on my computer, I can�t view any of them. Not examples that come with the SDK, none that I�ve compiled myself, and none that I�ve downloaded. Needless to say, in my exasperation I�ve run through every possible permutation of html code for class and classpath and so on trying to modify code into working, but to no avail.
Now, in the appletviewer, and in an IDE called RealJ, I can run applets just fine. It�s just those embedded in web pages that seem to give me trouble.
I�ve uninstalled and reinstalled j2sdk 1.4.1. I�m running IE 6.0. Windows 98SE. In my Internet options, I have under Java (Sun) the �Use Java 2 v1.4.1 for applet� box checked, and under Java VM the �Java console enabled� and �JIT Compiler� boxes checked, though I have also gone through every permutation possible here, again, to no avail.
Any idea what I can change so that I can start running applets with ease?
Thanks in advance, I desperately appreciate whatever suggestions you can give.
Travis

gray screen whenever I try to view an applet.
Now, looking around online, there are a few applets
that I�ve been able to access, and many I haven�t; Basically it is partly your browser and partly the version of the jdk /sdk that you are viewing. Generally, IE does not support swing ie JApplet, JButton, JTextArea etc... which is a shame cos it has some pretty neat features - I particularly like the flexibility with textfields and textAreas - and my favourite: imageIcon, allows you to have the sexiest looking buttons in the known universe. For reasons like this, people who like to write Applets like to use swing ... and people who like Sun don't like windoze and IE and the like (and they definitely hate each other). So, if you change your browser to Netscape or Opera - you will see swinging applets galore.
Shame really on a practical level, as the last survey I saw gave IE a 85 - 90 % share of the browser market. A bigger shame, when it seems to be deliberate that m-$oft do not include the latest JVM in their browser, yet they have the latest Flash plug-in. Both are in fact a good idea.
Any idea what I can change so that I can start running
applets with ease? Don't use swing and get a copy of something like jdk1.1.5 or even 1.1.2, if it compiles OK with this then it should be OK, keep it simple - as applets download on the client-side and can be unreliable and erratic so try and avoid images. Generally though Applets are a little bit out of vogue at the moment.

APPLET.class not found error on explorer!! need solution URGENTLY!!!

Hi,
I am calling my applet from a jsp and trying to run it on the internet explorer but I am getting the following error:
load: class /WEB-INF/classes/Log/LogApplet.class not found.
java.lang.ClassNotFoundException: .WEB-INF.classes.Log.LogApplet.class
My Explorer version is 6.0 and I am using Plug-in: Version 1.4.1_05. Why do you think it cannot find the class? it is located under the specified directory which is:
/Web Content/WEB-INF/classes/Log/LogApplet.class
and my jsp which is calling my applet is located under:
Web Content/Login.jsp
this is a very urgent problem!! could you please help me? I will appreciate your help so much.
Thanks,
Sofia
here is how I wrote my jsp:
<jsp:plugin type="applet"
code="/WEB-INF/classes/Log/LogApplet.class"
width="600"
height="620"
>
<jsp:params>
</jsp:params>
<jsp:fallback>
<p>Unable to start plugin.</p>
</jsp:fallback>
</jsp:plugin>
...

I'm having the same problem...however my applet is located outside of the web-inf folder. the web-inf folder is only for servlets. applets can't be recognised inside it since that folder is for server-side application while applets are meant for client-side.
i put my applet into a separate folder in the root directory of the webapp but it's generating a security error when i call it using a jsp page. so far the only way i got around it was specifying the entire codebase using localhost...but it's not a pretty good way of doing it.
any ideas anyone?

Class not found with APPLET

Hi all,
I know many have posted about the different version of java plugin will cause some strange behavior of an applet in loading. In my case, it can't load at all. (with plugin version 1.4.1)
SO anyone find the final solution?
thanks in advance

Sorry, not here to offer a solution but to report a similar problem. But in my case, the version is 1.3.0_03 and the error message is "PrintApplet.class not found." which appeared at the foot of the browser. (using WINDOWS 98; I/E 5.5) Can anyone help?

Load: class .class not found.

Load: class .class not found.
java.lang.ClassNotFoundException: .class

basically just stating where the class is expose to be.
This is an applet that i try to run its be made on another computer and compiles fine on the other one. I reinstalled my desktop and i downloaded the jdk se 6 release 6 and i use textpad to wright and compile. My problem comes after i compile the first time i try to run the applet i get a ClassNotFoundException but then the second time it works. It is not the biggest problem in the world just a little annoying and something that i would like to fix if i can. Thanks for the help.

yeah its kinda strange it happens for me every time consistently when a new class file is created with a compile the first time an applet is run it will give then class .class exception that i cant find information on. If there is no class in the folder such as i delete it and then run the applet the class "name".class a cures witch i see a few times on the internet but the first run failing is strange everything is in the right place and the class is in the right folder just the first time it is accessed it will fail but every time after it will work until a new compile and a new class is created
does anyone else get this maybe i can figure out if its my jdk or my OS or the raid drives messing up or something i cant think of.
i'm using the 6se update 6 maybe i should try beta release 10 i'm also using the 1.5 3d but i have not worked the bugs out of 3d yet. all on windows xp 32bit i was having to problem with 64 bit also but that os crashed and i haven't gotten to reinstall it. the class file is located in a single drive raid i mean the drive is considered raid but it has no link to the other drives. Drivers i believe to be up to date not more then a couple weeks old if they are.
I removed and reinstalled the jdk but same problem any information is appreciated. thanks.

"load: class */*.class not found." error

Hi...I'm making an applet in SUN ONE, and when I try to run the program, the applet doesn't initialize, and I get this error:
load: class LSLENDB/LSLENDB.class not found.
It doesn't tell me anywhere in my file where the error comes from. Note that the file is LSLENDB.java, and the class is named the same (LSLENDB). Any suggestions?

but i don't agree with your suggestion,
because he put his files in package, he must use:
<applet codebase=".." code="LSLENDB" .......></applet>
if he would like to have applet tag like:
<applet code="LSLENDB"></applet>
he should remove "package LSLENDB;" line from head of his applet source code.

IE Applet: load: class jreCheck.class not found.
