More memory: Ant and manifest

[Karsten Wutzke]

How do I make my application allocate more memory on startup? Production
version is a simple JAR file, so it might work with some setting in the
manifest, doesn't it? It so, what does the entry look like?

How do achieve the same using Jakarta Ant?

TIA,
Karsten

What about a simple wrapper script which would set -Xmx etc parameters prior
to calling -jar your.jar?

Hmm. One of the requirements by my prof is, that the app should be
double clickable in a file manager, so this is not quite acceptable.

Isn't there any way by the manifest/JAR mechanism to set the -Xmx
option? Or is there a way to do that internally in my program?
