Java Web Start - config question

[hsienda]

Hey all,
i have built a Java Web Start application. i package my
application(includes client's config.xml) into the jar. If client
saves and changes config.xml in the jar will it download the whole jar
again? If the answer is that it will download again, Is there any
solution let client can keep their config file?
