anything else needs to setup, how application unable to find the java version though it is there.

Check your application documentation to see where it expects to find Java.

Many Java applications expect Java to be located in a specific directory, for example '/usr/java', '/usr/bin/java', or wherever.

If you (for example):

# ls -l /usr/java

it will show you that this directory is symbolically linked to the actual Java directory, V1.6, V1.8, or whatever.

When you installed 1.8 the 1.6 directory was not removed so you have two versions to choose from. You might well need to change the link from the 1.6 directory to point to the 1.8 directory.

Many applications do not utilise $JAVA_HOME but expect to find Java in a specific directory. Find out from the application documentation what path that is.

Another thought is, does the application definitely need 64-bit Java or is it looking for 32-bit Java?

Perhaps you ought to post your hardware type, OS and version
