Forcing a commit in a JAVA stored procedure

Question

Hi,
I am using a java stored procedure which updates few tables ;only after it completes the call the commit is happening;But i wanted it to commit the tables as and when the processing happens not at the end of the call to java stored procedure because the GUI is polling for changes into the database which will be updated by the stored procedure.
i have already set the connection.setAutoCommit(true) in the code.
Can somebody suggest a solution ?
Thanks in advance

Jason,
Works for me on Oracle 10.1.0.3 running on Red Hat Enterprise Linux AS release 3 (Taroon).
Java code:
import java.sql.*;
* Oracle Java Virtual Machine (OJVM) test class.
public class OjvmTest {
  public static void test() throws SQLException {
    Connection conn = DriverManager.getConnection("jdbc:default:connection:");
    PreparedStatement ps = null;
    ResultSet rs = null;
    try {
      ps = conn.prepareStatement("select 'TEST' from SYS.DUAL");
      rs = ps.executeQuery();
      if (rs.next()) {
        System.out.println(rs.getString(1));
    finally {
      if (rs != null) {
        try {
          rs.close();
        catch (SQLException sqlEx) {
          System.err.println("Error ignored. Failed to close result set.");
      if (ps != null) {
        try {
          ps.close();
        catch (SQLException sqlEx) {
          System.err.println("Error ignored. Failed to close statement.");
}And my PL/SQL wrapper:
create or replace procedure P_J_TEST as language java
name 'OjvmTest.test()';And here is how I execute it in a SQL*Plus session:
set serveroutput on
exec dbms_java.set_output(2000)
exec p_j_testGood Luck,
Avi.
