Derby memory

[Jeremi Thebeau]

Hi,

I'm using the juddi-portal-bundle-3.0.0. package and would like to know 
if there is an easy way to change the derby.storage.pageCacheSize 
property to give derby some more memory. I've read that I can create a 
derby.properties file but I'm not sure in which directory it should go.

Thanks

Jeremi
