Starting Suns Sample App webpad

[don cline]

I am new to Java Web Start. I am trying to run Sun's Web Start example
webpad. I am using Tomcat 4.1.31

I built the webpad war file according to instructions:
"To build .war file, run below command inside the war directory
jar -cvf ../webpad.war ."

I placed the war file in the $TOMCAT_HOME/webapps directory and restarted
Tomcat.

I went to the associated web page at:
http://localhost:8080/webpad/war/index.html

So far, so good.

I tried to launch the webpad app and got an error:
"An error occurred while launching/running the application.
Category: Launch File Error
The field <jnlp>codebase has an invalid value: $$codebase"

On the exception tab it lists:

BadFieldException[ The field <jnlp>codebase has an invalid value: $$codebase,$$codebase]
at com.sun.javaws.xml.XMLUtils.getAttributeURL(Unknown Source)

at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source)
at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source)
at com.sun.javaws.Main.main(Unknown Source)

What did I leave out?

Hi,

I assume that your localhost:8080/webpad/war/index.html page has a link to the .jnlp file that the user clicks on.

Can you post the contents of this file. It may be a bit more obvious what it going on then.

Cheers, Jared.

OOPS...

One of the lines in the .jnlp file is incorrect and should read:

<jnlp spec="1.0" codebase="$$codebase">

The line I showed was an attempt to fix the problem...
