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.
![select new web application.jpg]()
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
