Webstart unable to find the Bea licence file

Question

Hi All,
We are using an web application with weblogic server and webstart. We are currently trying to convert the application from T3 to T3s protocol. For this we require the license.bea file to be set in the client side class path.
When i place this license.bea in the download directory of the webstart (where all signed the jar's and .jnlp file is downloaded) and launch the .jnlp file,it works.But when the .jnlp file is called throug the application it fails to locate the license file. error message:
<<Missing license file for: WebLogic Platform 8.1>>
The .jnlp file is as below :
<?xml version="1.0" encoding="UTF-8"?>
<jnlp codebase="http://dbnexus.int.risk.db.com:80/webstart/" href="launch.jnlp" spec="1.0+">

</jnlp>
In the above code i have specified the Bea.home as .\ so that it picks up the license from the same directory. We do not want to place the file at other place and hard code the path in the code as the path might differ in different systems where the application will be downloaded.
Is there any way by which we can achive the above. Is it possible to place the .bea file inside any jar and access it from the same. Please advice.
Thaks in advance....

The problem is,the appliaction is not able to find
the license file from within the .Jar.
is set the property as :
Dbea.home="c:/Documents and Settings/All
Users/Application
Data/JavaCache/http/Ddbnexus.int.risk.db.com/P80/DMweb
start/" and it works
But if i giv the path of the jar file it does not :
-Dbea.home="c:/Documents and Settings/All
Users/Application
Data/JavaCache/http/Ddbnexus.int.risk.db.com/P80/DMweb
start/RMwlcipher.jar!/license.bea"
How can i make the licence file insidethe .jar file
readable by the application ?
Or is there any way by which i can download the .bea
file to the webstart catch(I.e the download
directory). I am able to download the .jar using
<resources>
<jar href="wlcipher.jar" download="eager"/>
</resources>
Please advice.........

The problem is,the appliaction is not able to find
the license file from within the .Jar.
That is because there is no such "file" on the client machine.
c:/Documents and Settings/.../DMwebstart/RMwlcipher.jar!/license.bea"
is not a path at all. (notice the "!" between the jar and the file in it.)
After you call getResource you have a valid url to the file, but URL.getPath() will not return a "path" that can be used by the file system.
You have to open a URLConnection to that URL and read the stream that is the file contents, and store it as a file somewhere on the filesystem.
(Instead of getResource(), you can just use getResourceAsStream())
