perfsonar development work

As described in
http://java.sun.com/developer/technicalArticles/WebServices/JWS_2/JWS_White_Paper.pdf
chapter 4: security. " The Java Web Start Sandbox
Unsigned JAR files launched by Java Web Start run in the sandbox, meaning
they cannot access local files or the
network. "

and:

"Providing for Functionality Beyond the Sandbox
Java Web Start supports signed JAR files so that your application can work
outside of the sandbox described
above.
Java Web Start verifies that the contents of the JAR file have not changed
since it was signed. If verification of a
digital signature fails, Java Web Start does not run the application.
When the user first runs an application as a signed JAR file, Java Web
Start opens a dialog box displaying the
application's origin based on the signer's certificate. The user can then
make an informed decision regarding
running the application."

I think a signed jar in combination with:
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/System.html#setProperty(java.lang.String,%20java.lang.String)
should allow for setting the right parser.

that aside looking into the dependences creating this problem might not be
a bad idea neither.

regards,

Michael.

Ps. what is the other reason for abandoning jws?
