I cannot execute an procedure in Java that is a "select ... for update" stt

Question

I have a table with a column that has BLOB types. First I insert into that table with EMPTY_BLOB(). After I create a procedure as:
PROCEDURE file_content_select
        p_id IN NUMBER,
        p_file_content OUT BLOB
   IS
BEGIN
    SELECT f.file_content
    INTO p_file_content
    FROM files f
    WHERE f.id = p_id
    FOR UPDATE of f.file_content;
END; In my java program. I do that:
my query string:
query = ""
                    + "BEGIN FILE_CONTENT_SELECT ("
                    + id
                    + ",?); END;";and my execute query code:
callableStatement = connection.prepareCall(query);
callableStatement.registerOutParameter(1, OracleTypes.BLOB);
callableStatement.execute();
dataBlob = (BLOB) callableStatement.getObject(1);But, I seem to stop at
callableStatement.execute();where I'm wrong? Thanks for help me.

When you say, "locked" was already deselected, I take it that you mean the small icon at the bottom right of the Get Info window displayed an open lock picture.
Have you tried locking it, then unlocking it again?  I expect you will be able to lock it by simply clicking on the open lock icon, but to unlock it again you will need to supply an Admin password.
Odd that DU didn't fix it.  That would be my first thought also.  Suggest trying it again, if you haven't already done so.
Speaking of DU, have you verified your HDD?
