Passing filehandles in Java Stored Procedures

[Leslie Chaim]

How do I publish (write a call spec) for a method with a BufferedReader parameter.
For example I have a method.

public static void get_data(BufferReader br)
{
   ...
}

How do I properly write the call spec

create or replace procedure get_data ( ??? )
as language java
name 'Test.get_data(java.io.Bufferedreader br)';

What do I put in-place of the ???
