Calling java program in bipublisher

Question

Hi,
Like we have datamodel types in BIPublisher as SQL Query, Webservice, Answers, File etc,, Can we call java program through bipublisher.
The requirement is:
A java program will generate BARCODE image based on the customer number given.
We need to create a template in bipublisher which shows the customer name and that barcode image and other details.
We have calling javaprograms in ibots in analytics, is there any such thing in bipublisher.
Thanks.

You can call PL/SQL programs from OWB either by defining transformations or as expressions. From PL/SQL you can call a java stored procedures in the database as follows:
1. Define the java stored procedure. For example, let's suppose that you store the following Java class in the database:
import java.sql.*;
import oracle.jdbc.driver.*;
public class Adjuster {
public static void raiseSalary (int empNo, float percent)
throws SQLException {
Connection conn = new OracleDriver().defaultConnection();
String sql = "UPDATE emp SET sal = sal * ? WHERE empno = ?";
try {
PreparedStatement pstmt = conn.prepareStatement(sql);
pstmt.setFloat(1, (1 + percent / 100));
pstmt.setInt(2, empNo);
pstmt.executeUpdate();
pstmt.close();
} catch (SQLException e) {System.err.println(e.getMessage());}
2. The class Adjuster has one method, which raises the salary of an employee by a given percentage. Because raiseSalary is a void method, you publish it as a procedure using this call spec:
CREATE PROCEDURE raise_salary (empno NUMBER, pct NUMBER)
AS LANGUAGE JAVA
NAME 'Adjuster.raiseSalary(int, float)';
3. Call procedure raise_salary from an anonymous PL/SQL block, as follows:Long postings are being truncated to ~1 kB at this time.
