I figured out what the problem was

it was in the /etc/alternatives directory
despite changing the java version using "alternatives --config java"  
there was still a symlink "java_sdk -> /usr/lib/jvm/java-1.5.0-ibm.x86_64"
this symlink was bing set by one of the scripts as part of the path for 
java libraries I determined i didn't really need java-1.5.0-ibm-devel so 
i erased the package via yum it and now i works.
