Create my own Java installation.

Hi everybody.

I don't know if this is possible or what I'm asking is stupid, but I'm still learning.

I developed my first app and I'm already distributing it to my clients with a SetUp containing my app, my files and a java 1.7 installation. The total in mb of my SetUp is 30mb approximately.

So my question is, since I'm not probably using the whole Java library (files, wherever) that Java1.7 install, is it possible to find out what libraries, or packages I'm using and only install that in my clients computer?

Thanks, and I hope somebody can help.

I tried to be very clear, sorry for my English and my ignorance.

Notting?

I don't know if it is possible to take a subset of the components of the JRE for tailoring an installation.

Is there any way to compress that java installation file, so it wont be as heavy as it is now.
