Collecting DBMS_OUTPUT with JDBC?

Question

I am submitting dynamically-generated PL/SQL code as a query from a Java program using JDBC (classes12.zip).
Is there any way to trap DBMS_OUTPUT results (logging information, progress info, timing results, etc.) in Java?
Are there alternative methods of generating free-format output in PL/SQL that can be collected by JDBC?
Preferred solution would be portable across databases (no server-side components) and able to handle a variety of dynamically-generated PL/SQL scripts.
Thanks,
Bill

Found the fix in my PL/SQL book.
DBMS_OUTPUT.PUT_LINE data is spooled in a buffer available for the duration of the session.
In the PL/SQL, replace "set serveroutput on size 100000" with "DBMS_OUTPUT.ENABLE(100000);" in the BEGIN/END block.
To get at the data, I run four statements after the main PL/SQL submission returns:
1) create a temp table (called delete_me in this example)
2) Run a PL/SQL block to dump the buffer to the temp table (GET_LINES is doing the work):
DECLARE
v_Data DBMS_OUTPUT.CHARARR;
v_NumLines NUMBER;
BEGIN
v_NumLines := 100000;
DBMS_OUTPUT.GET_LINES(v_Data,v_NumLines);
FOR v_Counter IN 1..v_NumLines LOOP
INSERT INTO delete_me VALUES (v_Data(v_Counter));
END LOOP;
END;
3) SELECT line FROM delete_me;
4) Drop temp table
