I create a package in oracle that need to be tested in java.  What am I supppose to do?

By Suman

It's not a tough thing.

Say for example you have a package pkg_manage_emp_info, and inside it there a proc/function sp_select_emp_leave(in,in,out,in out) that you need to be called from java class....

Need to import the following classes/interfaces:------>>>>

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;
import oracle.jdbc.internal.OracleTypes;

and ojdbc14.jar need to be in your project classpath. 
CallableStatement cstmt = 
null; 
String queryString = 
"{CALL pkg_manage_emp_info.sp_select_emp_leave(?,?,?,?)}"; 
Connection conn = 
null; 
try
{
Class.forName(
"oracle.jdbc.OracleDriver"); 
conn = DriverManager.getConnection(
"jdbc:oracle:thin:@127.0.0.1:1521:DB_NAME", "user_name", "password"); 
cstmt = conn.prepareCall(procedureString);
cstmt.setString(1, 
""//set the value of in parameter); 
cstmt.setString(2, 
""//set the value of 2nd in parameter); 
//for out or in/out param--- 
cstmt.registerOutParameter(3, Types.VARCHAR,
//if it is a ref_cursor type out var then use --OracleTypes.CURSOR); 
cstmt.registerOutParameter(4, Types.INT);
cstmt.executeQuery();
String empBalLeave = (String) cstmt.getObject(3);
//if it is a ref cursor then 
//ResulSet rs = (ResultSet)cstmt.getObject(3);
while(rs.next){
---
}

}
catch
(Exception ex) 
{
ex.printStackTrace();
}
