I'm trying to set a specific version of Java for DPA to use. Maybe this is a bad idea, but I was going to have DPA use the latest version of Oracle Java 7. I noticed there is a file at iwc/tomcat/ignite_config/java_loc.txt with the path to Java in it. I changed it to point to the path I wanted and restarted DPA, but the startup.sh script still reports that it is using version of Java that ships with DPA.
Figured it out. The startup script echos the path minus the bin/java piece while the java_loc.txt file requires the full path including the /bin/java piece.
