SQL & PL/SQL :: ORA-29283 - Invalid File Operation?

We are using the below procedure to generate the files on the DB server.

SQL> create or replace procedure write_to_file(p_dir varchar2,
2 p_file varchar2,
3 p_mode varchar2,
4 p_clob clob) as

6 l_amt number default 32767;
7 l_offset number default 1;
8 l_length number default dbms_lob.getlength(p_clob);
9 new_clob clob;

12 l_output := utl_file.fopen(p_dir, p_file, p_mode, 32767);
13 while (l_offset < l_length) loop
14 new_clob:= SUBSTR(p_clob,l_offset,l_amt);
15 utl_file.put_line(l_output, new_clob,true);

This works fine we call this from PL/SQL developer tool. However, when this procedure is called from Java JDBC, it is giving error

java.sql.SQLException: ORA-29283: invalid file operation
