Can runtime parameters exist inside JAR Files?

Can runtime parameters exist inside JAR Files? I would like to include
runtime heap (e.g., -Xmx512) parameters inside my JAR file.

Technally you can put any file in a jar. The trouble is getting
it out
and using it.

I know that any file can be included in the jar, but can the runtime
parameters be passed to the JVM from the Jar file.

I looked in the manifest spec but saw nothing, but I vaguely remember
seeing an example of such. It might have been for jet though which is
something altogether different.

If you want to look yourself, see http://mindprod.com/jgloss/jar.html
and follow the link to the manifest spec.

Has anyone seen an example of runtime parameters being used from within
the jar file?

It's a hack, but you can always invoke yourself with the required
parameters.

There is the Javac -J option to burn them into the class files.

Presumably if you burn them into the main class they will be burned
into the jar.
