tomcat 7 recognizes the java as 1.6 ( the previous version) and gives this message

AFAICT Java 7 has removed $JAVA_HOME/jre/lib/<architecture>[/<vmtype] and $JAVA_HOME/lib/<architecture>
from the default java.library.path - this is independent of Tomcat. So it is very likely that
Tomcat *is* using the desired Java now. Others have already written how to verify for sure.
