</style>

<link rel="stylesheet" type="text/css" href="datepicker.css"/>


<script type="text/javascript">
function trim(str) {
if(!str || typeof str != 'string')
return null;
return str.replace(/^[\s]+/,'').replace(/[\s]+$/,'').replace(/[\s]{2,}/,' ');

String userName = "root";
String password = "root";

int sumcount=0;
Statement st;
try {
Class.forName(driver).newInstance();

conn = DriverManager.getConnection(url+dbName,userName,password);
String query = "select * from employee_details where eid='"+emp_id+"'";

st = conn.createStatement();
ResultSet rs = st.executeQuery(query);
while(rs.next())
{
data = rs.getString(2) + " " + rs.getString(3);
}

Document document=new Document();
PdfWriter.getInstance(document,new FileOutputStream("c:\\hello.pdf"));
document.open();
document.add(new Paragraph(data));
document.close();

out.println("ok");
}
catch (Exception e) {
e.printStackTrace();
}
%>
