How to insert jsp testbox values in sql database in button click
plz help

Submit the page to a servlet or a jsp, take the value of the testbox from the request, call a method with the value as argument, that method should have code that inserts in the database, redirect to whatever page you want, or stay at the same jsp.

JSP Code

<input type="text" name="someData" id="someData" />

Servlet Code

String strSomeData=request.getParameter("someData");
 dataManager.getConnection();
 dataManager.getUserData(strSomeData);

connection method

public void getConnection()
{
   // Connection coding
}
public void getUserData(String strSomeData)
{
   // insert query 
}
