import cruit.vo.SearchProjVO;

public final class SearchProjDAO { private static InitialContext context; String CLASS_NAME="DBConnectionFactory";

public void  submitProjectDetails(SearchProjVO searchprojVO) 
{
    String methodname="createConnection";
    Connection conn  = null;
    PreparedStatement psmt;
    try {
        System.out.println("searchprojVO id=="+searchprojVO.getProjid());
        System.out.println("in DAO");


        conn = DBConnection.getJNDIConnection();
        ArrayList ar = new ArrayList();
        ResultSet rs = null;
        while(rs.next())
        {
            SearchProjVO searchprojVO = new SearchProjVO();
            psmt= conn.prepareStatement("select * from CR_EMPLOYEE_DETAILS");
                psmt.setString(1,searchprojVO.getProjid());
                psmt.setString(2,searchprojVO.getProjname());
                 psmt.setString(3,searchprojVO.getCost());
                psmt.setString(4,searchprojVO.getManager());
                psmt.executeQuery();
                ar.add(searchprojVO);
                            }

        System.out.println("conn==="+conn); 
    } catch (Exception e) {
        e.printStackTrace(System.err);
    } 

}

} SearchProjVO import java.io.IOException; import java.sql.Connection; import java.sql.DriverManager; import java.util.PropertyResourceBundle; import javax.naming.InitialContext; import javax.naming.NoInitialContextException; import javax.sql.DataSource;

public final class SearchProjVO {

String projid;
String projname;
String cost;
String manager;

public String getCost() {
    return cost;
}
public void setCost(String cost) {
    this.cost = cost;
}
public String getManager() {
    return manager;
}
public void setManager(String manager) {
    this.manager = manager;
}
public String getProjid() {
    return projid;
}
public void setProjid(String projid) {
    this.projid = projid;
}
public String getProjname() {
    return projname;
}
public void setProjname(String projname) {
    this.projname = projname;
}

}

in SearchProjDAO i have to call servlet also how can i do this i have connected to data base
