How JVM represents NULL internally

I am curious to know how JVM represents a Null internally.What would be the bit pattern.?Can some one give information about this. I m trying to map null value of java to some legacy database null value.

Null is represented any way the runtime wants. The Sun JRE (and probably most other runtimes) happens to represent it as all bits zero. But you shouldn't care; you can't see the actual representation (without JNI). There is no "getBitPatternOfPointer()" method. If you use JDBC with a database, setNull() will do whatever conversion is necessary.
