Problem Configuring JDK7 in Opensuse 11.3

Hi Guys.
Today I downloaded Java Development Kit 7 RPM from Oracle website and sucessfully installed it in my System running Opensuse 11.3.
Previously I installed openJDK6 SDK provided with the opensuse 11.3 DVD. It worked fine.
But now after installing JDK7 and uninstalling openJDK6, I cannot run “javac”, Jar commands. In other words system is unable to find JDK binaries.

Is it safe to include the jdk/bin path in PATH variable and to place a .sh file in /etc/init.d/ to add the path in PATH and to export JAVA_HOME variable.

If it is safe the how to append in the PATH variable. For JAVA_HOME , I can do it my self.

Thanks…
