java调用pl/sql报表报错，求指教啊 ！
java代码如下

package com.oracle.www.produce;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class Package2 {
public static void main(String args[]) {
int i = 0;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection(
"jdbc:oracle:thin:@192.168.0.210:1522:TEST", "apps",
"appstest");
Statement stmt = conn.createStatement();
ResultSet rset = stmt
.executeQuery("select BANNER from SYS.V_$VERSION ");
while (rset.next())
System.out.println(rset.getString(1)); // Print col 1
CallableStatement cs = conn
.prepareCall("{call CUX_YI_ORG_PKG.main(?,?,?,?,?)} ");
// cs.setString(1,null);
// cs.setString(2,null);
cs.registerOutParameter(1, oracle.jdbc.OracleTypes.VARCHAR);
cs.registerOutParameter(2, oracle.jdbc.OracleTypes.VARCHAR);// 输出参数
cs.setInt(3, 83);
cs.setString(4, "2012/01/05 13:53:41");
cs.setString(5, "2012/10/05 13:53:41");

// System.out.println("i="+i);
cs.execute();
ResultSet rs = (ResultSet) cs.getObject(5);
System.out.println("rs=" + rs);
while (rs.next())
System.out.println(rs.getString(1)); // Print col 1
stmt.close();
} catch (Exception e) {
e.printStackTrace();

} finally {

}
}
}


pl/sql报表如下：：：
