I am not really sure if the JAVA API access the OpenNebula DB. In any case you 
can easily obtain the ID of a host by its name (or the whole record for the 
matter of fact) by querying the sqlite DB like this...

SELECT host_name FROM host_pool WHERE host_name=<the_name_of_the_host>

If Ruby is a valid language for your development purposes you can take a look 
to the onehost command and the one.rb library

Hope this helps...
