Applet: .class Not Found

I'm a complete newbie in Java programming, but I'm definitely falling in love for it!...As a beginner I'm trying to practice by modifying some classes I've downloaded in this way:
I open downloaded class file with "CavaJ Java Decompiler" (first decompiler I've found), then I make some changes (little changes, like in colours, just to make experience), than I copy my new code in notepad, save it as .java (using same name assigned before), finally I compile it from DOS (javac myfile.class).
No problems till this, but once I overwrite original myfile.class with my modified one, the Applet doesn't start anymore: status bar says (myfile.class NotFound).
Can anyone give me a hint for this silly problem? Thanks so much in advance

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?

Codebase help. Applet class not found. Please help..

I have web application (WEB) and struts configuration on weblogic server. I have configured the struts xml to call a HTML under certain condition and the HTML in turn should load a applet. The HTML is getting called correctly but the applet fails to load.
My html is in the C:\xxx\yyy\web\billing directory and the applet class is in the
C:\xxx\yyy\web\WEB-INF\classes\com\zzz\kkk\jjj\billing\helper directory. The Applet class is in the package com\zzz\kkk\jjj\billing\helper . I tried all combination of codebase in the HTML but the applet is NOT FOUND.
Any help would be appreciated.
Thanks

>
The browser needs to grab the applet class, so it can
execute it locally.
I think that stuff in WEB-INF is never directly
delivered to the client -- the server denies that it
exists.
So create another directory under docroot that will
hold applet classes.Thanks. I moved the applet class to the same directory as the HTML file and it works now.

Java applet class not found exception for check scan

I am getting a class not found exception when trying to scan a check into a banking website. The application uses Java and the exception error has the name "com.epaysol.checkscanAppletV2" in the message. I have the latest Firefox and the latest Java installed. I tried going to an earlier version of Firefox and of Java where this app worked in the past and it does not work now in the earlier versions either. So I am now back to the latest version of everything.

Applet class not found error

Dear Techie,
I have one Applet , while calling that applet in jsp , i am getting the following error ,
load : class com.soft.Text.class
File not found exception
Here that browser telling that not finding the applet class file while loading , In my war file that applet class file is there ,
Is there any other solution to resolve or suggestion.?
Im importing some of the third party library like DOM and all , i have added all the jar files , so what do to ?
Regards,
Thangavel.L

We have a similar set up where we have a web app and an applet in a JSP page. You have to put your applet classes up above WEB-INF. So, if your structure for your webapp was:
tomcat/webapps/mywebapp
you'd want your classes under mywebapp instead of webapps/mywebapp/WEB-INF. In your case, if I read your package structure right, you'd want a Log directory under webapp that contains your LogApplet.class file.
I hope this works for you!

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!

JSP-class not found

My server already working properly in internet.It's a travel agent site.there after i include one more page for audio guide which is JMF with in the applet and it is plugin to my jsp page.It's work very fine in my local system.my server is Tomcat .But if i hosted to our server means it's giving applet class not found exception.
It is already having com package ,now i include my jmf package wol to it.
My root directory of this class file is
web-inf/classes/wol/PlaySongs.class
My server doesn't have JMF pack so,i just copy JMF.jar and Sound.jar to my web-inf/lib/ folder.and also to my server folder like tomcat/common/lib/ .Now i restart my server it's giving applet class not found exception.but it's working fine in local system.
I have using following jsp code.
<body>
<%
String fname = "file:" + request.getRealPath("AudioF") + "/button-1.mp3";
%>
<jsp:plugin type="applet" code="PlaySongs.class" codebase="/wol" width="300" height="20">
<jsp:params>
<jsp:param name="file" value="<%=fname%>" />
</jsp:params>
<jsp:fallback>
<p> Unable to start Plug-in. </p>
</jsp:fallback>
</jsp:plugin>Any one help me.
Regards
K.Suresh

the codebase should be a path into the webdir, not the WEB-INF dir. Your browser needs to be able to reach the applet class like any other resource.
My server doesn't have JMF pack so,i just copy JMF.jar and Sound.jar to my web-inf/lib/ folder.and also to my server folder like tomcat/common/lib/If you are already copying it to your common/lib folder, you don't need it in the lib folder of your webapp.

Class not found only using browser.

I can not run any of my java programs in my browsers. They work fine using the "java" command in a dos window or using the "appletviewer" command. But when I try to view them in a browser, the page appears to load fine but I get no program and the status window of the browser displays a class not found msg.
I've checked spelling, location, capitalization. Everything works fine outside the browsers but will not view in a browser. We had the same problem in school and the instructor just said to stick with the appletviewer for class.
I am running JDK1.2. Any suggestions?
John

Maybe you should try a newer JAVA version.
I had a similar problem, but with a (too) newer JAVA version.

That's very good to know of course, but correct me if I am wrong with saying that Java development not
limited to NewBeans or any other IDE use.
If somebody wants to deploy the applets within browser built-in JVM (which is really outdated and just
Java 1.1.6 compliant) he or she should compile applet with Java 1.1.8 (still available from SunMicrosystems). Generated classes will be recognized by both Netscape and IE.

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/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

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" 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
owen

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

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).
