deegree is happy with either sun-java5 (preferred) or sun-java-6,
GeoServer nedds sun-java-6,
gvSIG needs sun-java-5,

Then we should kick out the OpenJDK (unless other projects need it).

Let us ensure to install both sun-java-5 and sun-java-6 at the
localtions mentioned by Jorge:

Setting JAVA_HOME globally is no option after all, because at least
GeoServer and gvSIG will not be able to use the same settings here.
The different projects should take care of JAVA_HOME separately then.

Does this sound good to you?

Kind regards,
