Specify it on the command line for javac:

javac -Xlint:unchecked

Or if you are using Ant modify your javac target

  <javac ...>
    <compilerarg value="-Xlint"/>
  </javac>

If you are using Maven, configure this in the maven-compiler-plugin 

<compilerArgument>-Xlint:unchecked</compilerArgument>
