When I run java applets, I put the .class files in the same folder that the .html is. When you do this, dont use the codebase='classes', because it means that your class files is located in a folder called 'classes' and it wont work.


My mistake, I moved to build\classes folder, where I have my class file, and now I have this:

I want to put my jar file in html code

How can I put my jar file into my html?
I tried to use that:
<html>
<head>
</head>
<body>
<applet code=Tictactoe.class archive="Test.jar">
</applet>
</body>
</html>
My problem is that when Im trying to run my html code java is blocking my jar file.

Try to add your url (local or distant server url) in exception list on java settings panel.

ClassNotFoundException Java Applet

I get the ClassNotFoundException error when I make my html file with the code and jar file. Not sure why. Here's what I have:
<html>
<head>
<title>
Test Applet
</title>
</head>
<body>
<h2>Test Applet</h2>
<applet
code="Testing.class"
archive="myTestJar.jar"
width=550 height=300>
</applet>
</body>
</html>
I simply have the class in a jar file and tried to reference using archive but it doesn't work.

try this
<applet code=Testing.class
archive="myTestJar.jar"
width=550 height=300>
</applet>
The class has your main() I assume, the jar is the entire thing.
if,you're not taking packages into consideration. For instance, if the package is myPackage.vol3 then the line should read
<applet code="myPackage.vol3.Testing.class" archive="myTestJar.jar"
and put the html file in the project folded "INSIDE" the project folder.

Applet war project doesn't find applet class in jar

I have the following projects
>projectJar
>projectWar
Inside projectJar I have a class that extends Applet, the class's name is com.me.test.TestApplet. Then in the war project I include the jar and create an HTML file like the following...
<HTML>
<HEAD>
<TITLE>A Simple Program</TITLE>
</HEAD>
<BODY>
<APPLET code="com.me.test.TestApplet.class"
archive="WEB-INF/lib/projectJar.jar" WIDTH=256 HEIGHT=240> </APPLET>
</BODY>
</HTML>
However, when I try to load the applet I get a class not found exception for TestApplet. Can anyone see what I am missing?

You cannot serve a "PATH" under "WEB-INF". Move your "projectJar.jar" to another folder, perhaps "/jar/porjectJar.jar".

Where I save the applet in tomcat?

I call an applet through a JSP...where I have to save it? and what the .class and the .java file? in which root in tomcat so when I call it from the JSP to be appeared?
here is the applet call from the jsp
%><%# page language="java"%>
<html>
<body>
<jsp:plugin code="g7appletDialog.class" codebase="" type="applet" width="300" height="200">
<jsp:fallback>Unable to load applet</jsp:fallback>
</jsp:plugin>
<applet code=""g7appletDialog.class"" width="300" heigjt="200"></applet>
</body>
</html><%

The path to your servlet must be relative to your jsp. If you have a jsp in web-inf/admin/pages/index.jsp, then you can place the .class file in directory web-inf/admin/pages/ and just have code="g7appletDialog.class".
In case that you have a central repository for applets, lets say web-inf/admin/applets then you should change the code to code="../applets/g7appletDialog.class".
The ../ gets you one dir back. To go two dirs back use ../../ and so on...
