Hi, I am new to SEAM and i got a requirement to execute an oracle sproc from a seam-gen'ed Form which i replaced the code from one of the discussions to try out for myself. But there are some error messages displayed in my eclipse IDE saying:

The method execute(ConnectionCallback) is undefined for the type SimpleJdbcTemplate for this line:

BigDecimal result = (BigDecimal) template.execute(connectionCallBack);

What am i missing here? So far i don't see a consolidated listing of the sample code. So i just tried to patch up here and there (remove throws exception, etc.) as per advice. Did i patch correctly? Below is my action class:

package com.mydomain.testapp.action;

import java.io.Serializable;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.Types;
import java.math.BigDecimal;

import org.hibernate.sql.Template;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.springframework.jdbc.core.ConnectionCallback;
import org.springframework.jdbc.core.simple.SimpleJdbcTemplate;

@Name("testspcall")
public class Testspcall implements Serializable
{

   @In("#{jdbcTemplate}")
        private transient static SimpleJdbcTemplate template;

@SuppressWarnings("unchecked")
public static BigDecimal calcDistance(final String zipcode, final BigDecimal lat, final BigDecimal lon) 
{
        ConnectionCallback connectionCallBack = new ConnectionCallback() {
                @Override
                public Object doInConnection(Connection conexion_db)
                                {
                                        BigDecimal result;
                                        CallableStatement statement = conexion_db.prepareCall("{call CalcDistance(?, ?, ?, ?)}");
                    statement.setString(1, zipcode);
                    statement.setBigDecimal(2, lat);
                    statement.setBigDecimal(3, lon);
                    statement.registerOutParameter(4, Types.DOUBLE);
                    statement.execute();
                    result = statement.getBigDecimal(4);
                    return result;
                                }

        };

BigDecimal result = (BigDecimal) template.execute(connectionCallBack);
return result;               
}
