Strange: Jar file not working in HTML
Todd Hlavacek
I am at a loss as to why this situation is in my hands. :)
Seriously, I have packaged a JAR file with several classes and
resource files (all Gifs of 400 bytes or less).
I ran it just fine via the java -jar Foo.jar and java
-classpath=foo.jar etc etc -- all from the prompt using java.exe.
But I cannot seem to be able to run it via an applet on the web. The
applet has the following code:
<html>
<CENTER>
<!--"CONVERTED_APPLET"-->
<!-- CONVERTER VERSION 1.3 -->
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
WIDTH = "800" HEIGHT = "525"
codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0">
<PARAM NAME = CODE VALUE = "loApplet.class" >
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
<PARAM NAME="scriptable" VALUE="false">
<PARAM NAME="filename" VALUE="C:\Epoch\outbox\julieshi.solution5.oft">
<PARAM NAME="sessionid" VALUE="no_session_id_yet">

-->
<PARAM NAME="debug" VALUE="t">

<EMBED type="application/x-java-applet;version=1.3" CODE =

MAYSCRIPT="true" WIDTH = "800" HEIGHT = "500">
</APPLET>
-->
<!--"END_CONVERTED_APPLET"-->
</CENTER>
</html>
And the html and JAR files are in the same directory. I'm getting an
ClassNotFoundException error (output from Java Console using trace
level set to 5):
load: class loApplet.class not found.

I even tried changing the CODE from "loApplet.class" to "loApplet".
Same bat result.

By the way, this works if I put the *.class and *.gif resource files
in the same directory. I want the JAR file and not individual class
files.
Any ideas?
Thanks,
Todd

Credit to Gil Vincent for helping me out.
Hi Gil,
I wanted to bring closure to this by informing you that your latest
email did the trick! (that email was about plugging in archive in a
plain old applet (and non-html-converted) file then running it through
the html converter)
Wanted you to know.
If you'd like, I'll post your comments to google for others to look at
and give you due credit.

Hi Todd,
Assumption: java plug-in being used.
What does your html (just the applet portion) look
like? It might help me to identify the problem.
Also, did you use the old <applet> tag and use the
html converter to produce the actual tags, or did you
write them manually?
