Applet not initiated
Hello
When I am trying to open a very simple applet on my browser
it returns "applet not initiated" or "failed to load applet".
class file is located in tomcat WEB_INF/classes and I am calling it from
ROOT directory and through index.html file.
thanks for help
Adam

Posted by Abdelmonaam Kallali <ak...@dragonwaveinc.com>.
Hi everyone
I have an applet called by a jsp file but the applet is not initiated the
jsp file contains
rs1=stmt.executeQuery("select status, sum(counter) as counterSum, allDates
from(select * from(select distinct status, count(status) as counter
,dateOpened as allDates from ncrreport where unitSerNum!='no unit' and
dateOpened between curdate()-5 and curdate() group by allDates, status)as
opened union select * from (select distinct status,
count(status),dateClosed as allDates from ncrreport where unitSerNum!='no
unit' and dateClosed between curdate()-5 and curdate() group by allDates,
status)as closed )as allNcrs group by allDates, status");
while(rs1.next())
{
status = rs1.getString("status");
if((status.equals("closed")&& i%2==0)||(status.equals("open")&& i%2==1))
{
counter[i] = rs1.getString("counterSum");
dateOpened[i] = rs1.getString("allDates");
}
else if(i%2==0)
{
counter[i] = "0";
dateOpened[i] = rs1.getString("allDates");
counter[i+1] = rs1.getString("counterSum");
dateOpened[i+1] = dateOpened[i];
i++;
}
else
{
counter[i] = "0";
dateOpened[i] = dateOpened[i-1];
counter[i+1] = rs1.getString("counterSum");
dateOpened[i+1] = rs1.getString("allDates");
i++;
}
i++;
}
for (j=0; j<i; j++)
{
allDates+=","+dateOpened[j];
allCounters+=","+counter[j];
}
con.close();
%>
This is an applet template:<br>

g2D.drawLine( 10+10*j, getSize().height-counter[j],
10+10*(j+2), getSize().height-counter[j+2]);
g2D.drawLine( 10+10*(j+1),
getSize().height-counter[j+1], 10+10*(j+3), getSize().height-counter[j+3]);
}
}
}
can anybody tell me why it is not initiated (note that these two files are
in ROOT)

Also I don't know if you're using strict XHTML.
The applet tag is not supported in XHTML as mentioned here :
http://www.w3schools.com/tags/tag_applet.asp
they recommend using the HTML object tag
http://www.w3schools.com/tags/tag_object.asp instead of applet tag.

I recommend not setting the CLASSPATH at all.
I tested one Applet example with JSPs, and the applet loads fine on
Tomcat 6 / Windows XP without any explicit classpath settings.
Here's the code that works with JSP 2.0 if it helps you, the HTML
APPLET tag's syntax may be similar to the jsp:plugin tag's syntax as
shown below:
-----------------------------------------------------------------------------------------
C:\dev\projects\MyProject\appletTest.jsp
-----------------------------------------------------------------------------------------
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head><title>Applet Test</title></head>
<body>
<%--
http://java.sun.com/products/jsp/syntax/2.0/syntaxref2023.html#1004158
--%>
<jsp:plugin type="applet" code="HelloWorld" codebase=".">
<jsp:params>
<jsp:param name="commaSeparatedValues" value="abc,xyz,123,888"/>
</jsp:params>
</jsp:plugin>
<br/><br/><br/>
<%-- The following will not work, because HelloWorld2 is under WEB-INF --%>
<%--
<jsp:plugin type="applet" code="HelloWorld2" codebase="/WEB-INF/classes/test51">
</jsp:plugin>
--%>
</body>
</html>
--------------------------------------------------------------------------------------------------
I've placed the applet class in the same folder as the JSP file, but it could
be placed anywhere else under the project (except under WEB-INF)
C:\dev\projects\MyProject\HelloWorld.java
--------------------------------------------------------------------------------------------------
import javax.swing.JApplet;
import java.awt.Graphics;
public class HelloWorld extends JApplet {
public void paint(Graphics g) {
g.drawRect(0, 0,
getSize().width - 1,
getSize().height - 1);
g.drawString("Hello world!", 5, 15);
}
}
Cheers

Hello Rashmi,
Thanks for response,
I put the class file in ROOT directory, the same place that my html file
exist , but still the same problem.
is it possible classpath should include that class location so
computer's jvm
recognize the place that class is exist ?
and also I found some document that it says
codebase tag should cotnain the directory that class are located and
code tag should contain
the class name but without class.
your help will be highly appreciated.

Place your Applet's class file anywhere but the WEB-INF folder,
because WEB-INF folder is protected from client/browser's access,
applet classes can't be accessed if they are under WEB-INF.
Also use jsp:plugin tag , if you are accessing the Applet from a JSP file.
