The page doesn't gets refreshed

Hi,
I'm developing a site in which i'm continuously overwriting a file with more contents. But the page when refreshed doesn't reflect the changes.
However if i download the page using ftp, the page actually contains more data.
What could be the problem. Please help.
Also in a user input form, if the user enters a text containing quotes, then the sql query reports an error. Is there any possible solution.
Thanx in advance
Gaurav

What do you mean by "if I download the page using FTP, the page actually contains more data". What is being updated, the JSP page or the file? It's hard to figure out what you're doing wrong if we can't see your code.
The SQL error is caused by your building a query string dynamically from whatever the user enters:

You can see that if userInput contains "O'Brian", you'll get garbled SQL.
A better approach is to use a prepared statement:

Note that you don't need quotes around the "?", whether the value is numeric or string.
