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?

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/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

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">
</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.

HELP!! Nokia's API classes not found with j2me WTK

I setup j2me WTK, jdk1.4.2 and also Nokia's SDK (Series_60_MIDP_SDK_for_Symbian_OS_v_1_2_1) on my Win NT 4.0 machine.
J2ME samples (shipped with it) are working fine with ktoolbar. but when i try to build & run nokia samples, they are always giving error "FullCanvas class not found" and "package com.nokia.lcd.ui.* not found". I am sure it is the problem of placement of classes of nokia at correct place inside j2me's WTK. However, i followed the guidelines to install symbian sdk inside wtk401\wtklib\devices folder (as per instructions of forum nokia). But i am still not able to get it running. Any expert suggestions, then plz respond me , i am in urgent need to solve this issue!!!! plz help me!!!!

Hi,
Maybe I'm being thick but I can't get this work. I've tried zipping the com/nokia stuff into the midpapi.zip. And I've tried just replacing midapi.zip with classes.zip from the nokia emulator. But it still says:
"package nokia.mid.ui does not exist
import nokia.mid.ui.*;"
I'm using ktoolbar 1.04.
Many thanks!
CP
Hey, thanks for the great tip. Was also using
KToolbar because it runs faster on my slow laptop than
Sun One studio.
With the later version of WTK, the paths
C:\...\WTK21\lib contains 2 files, midpapi20.zip and
midpapi10.zip
The later contains classes for compiling to MIDP1.0
standard. I think most people use this. Replace it
the class.zip in
C:\Nokia\Devices\Nokia_7210_MIDP_SDK_v1_0\lib if
you're using the same SDK as I am, and don't forget to
rename it.
Cheers.

Class not found with jms cache sync

hi. when i try to use the remote command manager in my live environment only i get a class not found exception for my initial context factory. using a debugger i discovered this is actually hiding a linkage error. so i confirmed that my resin and java versions and all my jars are the same between live and stage, where this works no problem. but still doesn't work in production. any ideas what else i should look at? here's a stack trace

I would guess the problem is related to the application's class-loader visibility. Verify that your application can access the class org.exolab.jms.jndi.InitialContextFactory forio to launching the TopLink session. If it cannot then you may need to address the container's access to this library.

Class not found with j2sdk1.4.2_04 but no problem with MS VM

Hi.
there is an application on my company's intranet hat has some applets. I installed the j2sdk1.4.2_04 and whenever I start the aplication it says "java.lang.ClassNotFoundException", but if i turn of the j2se for applets (on IE 6.0 sp1: tools>internet options>advances>uncheck use java 2 for ...) and use the microsoft VM the application works just fine.
can someone help me???

It seems your application uses classes from Microsoft, not only common classes (JDK 1.1.4). What the name of class in ClassNotFoundException?

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.

This line from your error next could require control for the version in the "java control panel" of the jre(s).

note the proxy= and look in Network Settings in the *"java control panel"* (not the output panel).

Hi,
First of all thanks to you for replying for my request.
I had tried the option given by u but it will not work at all on remote server ,it work without any error on my local tomcat (Linux Server) .
But sometimes it displays on remote server,showing random behaviour of showing, not showing. Is there any Security permission issue ? .
I am using winXP,JRE version 1.5.0_06 Java HotSpot(TM) Client VM.
It is giving error when i upload it to my remote server also path is correct .

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.

"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 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..

Patch failing with Class not found: oracle.apps.ad.jri.adjcopy

Hi.
Running a patch today and it is failing with:
Class not found: oracle.apps.ad.jri.adjcopy
The log states this:

I have tried running maually and still no luck.
It is a frteshly cloned environment. Autoconfig has been run successfully.
The only help from Metalink was that I have unzipped the patches in a folfer with space in it. So I renamed folder but still same error.
The patch is 7415848 ATG Framework Patch.

Thanks in advance,

Another thing I tried was to relink, but got the following:
Do you wish to force regeneration of all jar files? [No] ?
Generating any out of date or missing jar files.
Signing product JAR files in JAVA_TOP -

You should check the file
D:\oracle\testappl\admin\TEST\log\adadmin.log
for errors.
D:\oracle\testappl\ad\11.5.0\bin>
