Class * not found - Applet error

Hello! I was just wondering how I would make it so my java applet would work with MSJava as well. At least that's what I'm assuming is the problem. It works fine just about everywhere, but my school computers use MSJava, and when trying to view the applet here, it doesn't load and produces a grey box with a 'class myClass not found' error in the status bar. If anyone knows how to fix this, I would be grateful. Thank you!

Make sure that you are not using code features that have been added starting with Java 1.2 and later (including any Swing code).
Try compiling the code with the javac option "-target 1.1"
If that doesn't work, download one of the old 1.1.x versions from Sun's archive page and compile with that.
If that doesn't work, examine the code and rewrite to be compatible (or forget it).

"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.

Never mind....the problem had to do with my CLASSPATH....

IE - "class not found" - Applet

I did several test with a simple Hello.java applet, compiled the same source code with JDK_1.3.1_09 and J2SDK_1.4.1_06/1.4.2_02.
It is clear to me that IE doesn't work when the applet has been compiled with a version newer than JDK_1.3.1_09.
With NetScape 7.1 I have no problems with any version.
What is the definitive solution for this behaviour ?
Thanks,
Wilhelm

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, Jdk1.4 matters?

Why drivers can't be loaded for this machine? Make me strugge for many hours already.
1)
Version j2sdk-1_4_2_07- (Java 2 se, 1.4)
Environment: Windows XP
I keep receiving "Class not found" exception error when running the following simple piece of codes for testing. (No complint When compiling). The code simply reads:
try {
System.out.println("driver loading test step 0 !!!....");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
System.out.println("driver loaded 1 !!!....");
System.exit(0);
catch (ClassNotFoundException ee) {
System.out.println("Clss not found\n" + ee.getMessage());
My other simple java codes got compiled and run ok in the same enironment.
2)
I then replaced the sun jdcd-odbc bridge driver in the test with a jdbc driver (for Sql server) downloaded from DataDirect.
That is: by replacing the one line above with the following. But it gives me classNot found Exception too. I don't think it has to do with classpath as I add it in the java command line already
Class.forName("com.ddtek.jdbc.sqlserver.SQLServerDriver");
3) I moved the codes to run in my old PC (Windows NT 4) with jdk1.3, the codes are compiled and run WITHOUT Class not found Exception.
I had more than a year experience in developing Java codes (though not recently) but what I experience now is so wierd to me. What's wrong with jdk1.4 or what's wrong with this XP machine?
Thanks.

99.999% of the time, something is wrong with your classpath at execution time, or with the classname you put in your code (those class names do look right though). That the same code works on another machine almost certainly means that something has set the classpath in the environment on one machine and not the other.
.001 percent of the time, something is wrong with your machine, such as a corrupted file system or OS. If so, reformat your drive, and reinstall everything. However, always, there will be other symptoms of problems (mystery crashes, disappearing files, etc.), so don't waste your time doing this unless your computer is already flaky.
Most likely, you just don't know how to set the classpath for execution. For that, use Google.

"class not found error" and applets ...

To run an applet inside an html page using the embedded oc4j i have to copy the library containing the applet to the same directory as the html page. Otherwise i get a class not found error....Is there a better way of doing this?
thanks in advance for any advise

Hi,
you should be able to reference the JAR file from teh HTML tag. If not then this sounds like a bug that should be filed

Class not found error for applet.

This is probally a really simple mistake but I've tried everything and can't find it.
My applet works fine with applet viewer - I'm running it from JBuilder. But when I open my html file in the browser it gives me a 'Class not found' error. I've tried running other applets (my own and demos on this site) and they work fine.This is the applet tag code:
<applet code = "Rotary.class" width = "650" height = "580" align = "top">

<param name = "sector0" value ="234,215,244,207,154,43,125,63">
</applet>
The class file is in the same directory as the HTML file. Do I need to specify the codebase? I tried that too - giving it the full pathname of the class.
In the Java console it said that it couldn't find "C:Project\Rotary\javax\swing\japplet"
I don't think it could have anything to do with the fact that I'm using swing because the other applets I used used swing.
Please help - I'm really running out of ideas here!

You have a similar problem like I had.
You seem to have a too old JAVA environment for the browser - I had a too new environment.
For all who are experiencing the same problem!
Problem:
You're compiling your applets with a quiet modern compiler (i.e. Netbeans Version 3.5.1)
You are able to compile your applets without any problems but if you try your applets in "real life", the browsers can't interpret your applets [class not found]. (I tested Internet Explorer 6.0 and Netscape Navigator 4.7)
So you need a plugin for the new JAVA environment because the JAVA environment of the browser is older than that which the applet needs.
Well, you have the choice to demand to every user of your applet to download the new Java Runtime Environment, but then don't wonder why nobody visits your site!
But, don't worry: I figuered out another solution, that Netbeans (www.netbeans.org) allows to compile in different JAVA versions.
Solution:
What you have to do is:
- Install a previous version of JDK (i.e. JDK 1.3 - I would suggest, lower versions don't work with Netbeans 3.5.1 and JDK 1.3 is enough for IE 6.0 and NN 4.7, which I tested)
- Go into the "bin"-directory of Netbeans (i.e. c:/netbeans3.5.1/bin)
- Open the file "ide.cfg" (with notepad or any other texteditor)
- You see a line like: jdkhome "C:\java\j2sdk1.4.2" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- Change the path to your other JDK you wish, like: jdkhome "C:\java\jdk1.3" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- That's it, you can compile your applets in a previous version of JAVA so that "older" browser user don't have to install a plugin for the new JAVA environment.
Have fun!
If you have any questions I would be pleased to help you.
If this tip helped you already I would be pleased if you would send me a quick email with your experience.

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 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

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

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!

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">

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.

Class not found error!!!

Hello,
I wrote a program that would read data from a file (present in one of my folders). I developed it as an applet and am able to see the result in appletviewer, but unable to see it in the browser(IE6-WIN2000). I did the HTMLConverter procedure and saw that it worked for all other files except this. The error it gives is:
load: rdbyte class not found
However, this class file is located in the same folder. And all the necessary methods like init() etc are present in my program.
Please help me!!!
Thanks

Do you have used any other package then default package?
Look at the documentation and search something like this:
<applet>
<param name="code" value="yourClass.class">
<param name="codebase" value="classFileDirectory">
</applet>
Your applet must be signed to read or write file from your filesystem.

I have my applet code in the applet folder
here is my jsp call
<applet code="MyApplet" codebase="../applet" archive="SMyApplet.jar" width=400 height=400>
</applet>
here is my applet code
package applet;
import java.applet.*;
import java.awt.*;
public class MyApplet extends Applet
public void paint(Graphics g)
g.drawString("Generate Me",50, 50);
}

If i do
<APPLET CODE="xxx.class" CODEBASE="." ARCHIVE = "skshrad.jar , javax.jar" WIDTH=500 HEIGHT=500>
is it correct?
because it still appeared class not found error..
This is a signed applet
thanks..
i try to put 2 directories in a jar also did not work..

I found the solution for this. my IE browser is not having java RMI plugin. this plugin you can download from IBM or Microsoft site.
