Problem loading applet from tomcat

Question

I am facing a problem loading the batik applet from tomcat. I have placed all the jar files of batik in ROOT directory in tomcat. Along with the folder containing the batik applet. Still i receive the following exception when trying to load the html page containing batik applet.
Applet tag in html page is:
<applet codebase = "." code="batik_applet.BatikApplet.class" name="myApplet" width="1600" height="1200" hspace="0" vspace="0" align="middle" archive="batik-swing.jar,batik-gvt.jar,batik-bridge.jar,xml-apis-ext.jar,batik-css.jar,batik-util.jar,batik-dom.jar,batik-svg-dom.jar,batik-anim.jar,batik-awt-util.jar,batik-codec.jar,batik-ext.jar,batik-extension.jar,batik-gui-util.jar,batik-parser.jar,batik-script.jar,batik-svggen.jar,batik-transcoder.jar,batik-xml.jar,js.jar,pdf-transcoder.jar,xalan-2.6.0.jar,xerces_2_5_0.jar,xml-apis.jar">
</applet>
I already have a folder named batik_applet containing BatikApplet.class in the ROOT directory.

Any help would be appreciated.

Answer 1

Assuming that your applet is not in a jar file (don't see a value for archive)
you have a file callsed ProcessStatus.class in a folder WEB-INF\classes relative to
the location of the jsp file.
So if the jsp file is in
myJSPFileFolder
the class should be in:
myJSPFileFolder\WEB-INF\classes
If you want to see when the jre is trying to load and where it it trying to load it from you
can inspect a full trace, to turn the full trace on (windows) you can start the java console, to be found here:
C:\Program Files\Java\j2re1.4...\bin\jpicpl32.exe
In the advanced tab you can fill in something for runtime parameters fill in this:
-Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect
if you cannot start the java console check here:
C:\Documents and Settings\userName\Application Data\Sun\Java\Deployment\deployment.properties
I think for linux this is somewhere in youruserdir/java (hidden directory)
add or change the following line:
javaplugin.jre.params=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
for 1.5:
deployment.javapi.jre.1.5.0.args=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
The trace is here:
C:\Documents and Settings\your user\Application Data\Sun\Java\Deployment\log\plugin...log
I think for linux this is somewhere in youruserdir/java (hidden directory)
The trace should show something like :
Caused by: java.io.FileNotFoundException: http://server/location/filename.class (The system cannot find the path specified)
