Isabelle settings are configured via etc/settings, either directly e.g. in 
your ~/.isabelle/etc/settings (for repository versions) or by initializing 
some Isabelle component.  The Isabelle System manual explains the general 
principles behind etc/settings and etc/components.

The jedit_build-20120313 directory is already such a component, so if you 
say init_component .../jedit_build-20120313 in your settings it should 
work.


There is some chance though that in more recent latest versions of 
Isabelle, say 89b13238d7f2, you get another problem if JAVA_HOME does not 
point to a proper JDK installation -- say the one of the 
Isabelle2011-1/contrib in the Linux bundle.  Here you need to set 
JAVA_HOME *outside* of the Isabelle environment or ISABELLE_JDK_HOME 
*inside* as settings.

I am in the course of refining that again soon ...
