Thanks for the response Lewis, I was having problems applying the patch, but I ended up applying it by hand. I noticed that most of the changes were on changing the classpath build folders to ones named target, I imagine this is due to maven right? Anyways, I am getting the now the same error described as GORA-137 even though I think I corrected the gora.sh file. We were always loading the gora/conf/gora.properties, and then getting the the $MODULE/conf into the classpath. So now the file is only getting the conf for the correct module, but for some reason it would still get the gora/conf/gora.properties Is there a place on the code that I should check? Thanks very much for your help! (:
Renato M.
