Creating Stored Procedure in Java

Question

Hi All,
I would like to ask how to create a stored procedure in Java.
My project now is to create a program that will open a DB2 SQL File (Creating Table and Stored Procedure) and then Execute it.
Executing the CREATE TABLE command is not that difficult since I can break the execution down by statement (divide by ";" in the SQL file).
The logic I applied here are:
1. Open the SQL file and store the contents into a String object.
2. Call the executeUpdate(string_sql_fileContent) method of Statement Object.
Example: SQL File contect to be executed.
===========================================================
CREATE TABLE MDMTEST.sample
(firstname CHARACTER(40),
middlename CHARACTER(40),
lastname CHARACTER(40),
idNo SMALLINT NOT NULL
DATA CAPTURE NONE;
#SYNC 10;
ALTER TABLE MDMTEST.sample
LOCKSIZE ROW
APPEND OFF
NOT VOLATILE;
#SYNC 20;
ALTER TABLE MDMTEST.sample
ADD PRIMARY KEY
(idNo
#SYNC 30;
RUNSTATS ON TABLE MDMTEST.sample
AND INDEXES ALL
SHRLEVEL REFERENCE;
===========================================================
I can divide this by ";" and execute them by statement.
But my problem is when creating Stored Procedure... Since in stored procedure there are so many stub-statements...
Example: Content of SQL File for creating stored procedure.
===========================================================
CREATE PROCEDURE MDMTEST.DROP_ALL_OBJECTS ( )
SPECIFIC MDMTEST.SQL051109115453000
LANGUAGE SQL
NOT DETERMINISTIC
CALLED ON NULL INPUT
MODIFIES SQL DATA
INHERIT SPECIAL REGISTERS
BEGIN
     Delete Statement;
     Insert Statement;
     Update Statement;
END;
===========================================================
Take note there are three statements inside the CREATE..BEGIN.. and END.. (namely Delete, Insert, and Update Statements).
How can I execute the command for creating the procedure in Java? I believe that creating stored procedures in other databases are almost the same...
So... anyboby who have tried creating stored procedure in Java?
Please help me in this... I wanna pass the subject hehe..

I have used these files as a sample:
Java Program:
import java.io.*;
import java.sql.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.border.*;
import my.db.components.*;
public class ProcedureUploader {
     private MyDBConnection dbConn=new MyDBConnection();
     private Statement statement;
public ProcedureUploader() {
     try{
          dbConn.connectDB ("206.206.206.206","12345","DEV","mdmtest","mdmtest");     
          this.statement=dbConn.getStatement ();               
     }catch(SQLException sqle){
          sqle.printStackTrace();
     public String getContents(String fileName) throws IOException{
          File inputFile = new File(fileName);
FileReader in = new FileReader(inputFile);
int c; String contents="";
while ((c = in.read()) != -1) contents+=(char) c;
in.close();
return contents;
public void executeSQLCommand(String file) throws IOException{         
     String command="";
     try{
          command=getContents(file);          
               statement.executeUpdate(command);
          System.out.println("Command Execution Successful.");     
     }catch(Exception ex){
          System.out.println("There is a problem executing the command. Please check the SQL file and re-execute again.");
          ex.printStackTrace();
public static void main(String args[]) throws IOException{
     ProcedureUploader uploader=new ProcedureUploader();
     uploader.executeSQLCommand("C:\\I2\\Development\\ProcedureUploader\\sample.sql");
SQL File:
CREATE PROCEDURE MDMTEST.sampleProc ( )
SPECIFIC MDMTEST.sampleProc
LANGUAGE SQL
NOT DETERMINISTIC
CALLED ON NULL INPUT
MODIFIES SQL DATA
INHERIT SPECIAL REGISTERS
delete from SAMPLE;
commit;
select * from SAMPLE;;
#SYNC 10;
===========================================================
The problem is that ... there will be an error:
===========================================================
There is a problem executing the command. Please check the SQL file and re-execute again.

===========================================================
But still the procedure will be created but until the first ";" only... OR.. creates a stored procedure having the following lines only.
===========================================================
CREATE PROCEDURE MDMTEST.sampleProc ( )
SPECIFIC MDMTEST.sampleProc
LANGUAGE SQL
NOT DETERMINISTIC
CALLED ON NULL INPUT
MODIFIES SQL DATA
INHERIT SPECIAL REGISTERS
delete from SAMPLE;
===========================================================
