 _defecto=javacomp
 _subcontexto=
 javacomp=puntocom.negocio.context.JavaCompBeansContextProvider
 jndi=puntocom.negocio.context.JndiBeansContextProvider
 

Or in English:

 _default=javacomp
 _subcontext=
 javacomp=puntocom.negocio.context.JavaCompBeansContextProvider
 jndi=puntocom.negocio.context.JndiBeansContextProvider
 

The entry _default/_defecto indicates the object used by default. The default object is created calling to indica el objeto usado por defecto. El create() without arguments. The classes used have to implement IContextProvider.
The entry _subcontext/_subcontexto indicates the lookup subcontext used, It can be left in blank or omit the entry, then it lookup from root subcontext.
