This is the next article in the series of database applications in JSP. In this article, I am going to describe the metadata in JSP. First we construct a database and then make the DSN generate a JSP application that uses the metadata concept. To construct a database and DSN you may follow the first application of database ( working with database application in JSP).

For this application you may follow the following steps.

Step 1 :
Create a New Project

In this step we select New Project option from file menu.

Step 2 : Choose Project

In this step we select web application from Java web option and then click on the next button.

Step 3 : Name and Location

In this step we give it a specific name and set a specific location and click on the next button.

Step 4 : Server and Setting

We select a specific server for this application and click on the next button.

Step 5 : Select Framework

There is no need to select any framework for this application, so just click on the finish button.

Step 6 : Create jsp file

We create one jsp file for this application.

metadata.jsp

<%@ page import="java.sql.*" %>
<% Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); %>
<HTML>
         <HEAD>
         <TITLE>
Using Metadata In Table</TITLE>
         </HEAD>
         <BODY BGCOLOR="green">
             <H1>Using Metadata In Table</H1>
             <%
                 Connection connection = DriverManager.getConnection(
                  "jdbc:odbc:data2");
                 Statement statement = connection.createStatement() ;
                 ResultSet resultset =
                 statement.executeQuery("select * from table1") ;
             %>
                 <TABLE BORDER="1">
                 <TR>
                      <TH><%= resultset.getMetaData().getColumnName(1)%></TH>
                      <TH><%= resultset.getMetaData().getColumnName(2)%></TH>
                      <TH><%= resultset.getMetaData().getColumnName(3)%></TH>
                      <TH><%= resultset.getMetaData().getColumnName(4)%></TH>
                      <TH><%= resultset.getMetaData().getColumnName(5)%></TH>
                   </TR>
            <% while(resultset.next()){ %>
                 <TR>
                      <TD> <%= resultset.getString(1) %></td>
                     <TD> <%= resultset.getString(2) %></TD>
                     <TD> <%= resultset.getString(3) %></TD>
                     <TD> <%= resultset.getString(4) %></TD>
                     <TD> <%= resultset.getString(5) %></TD>
                 </TR>
           <% } %>
                 </TABLE>
        </BODY>
</HTML>


Step 7 :
Compile and Run the application

Now we compile the application and then run it on the server and find the following output.

Output
