Capture JSP output, save to file

I am tasked with creating a site that will create custom HTML templates. Settings are configured for user input. I am currently using tomcat / JSP for the rest of the interface. I want to create HTML templates in JSP for outputting conditional HTML code, but instead of displaying this HTML output to the user, I would like to save this code in several files (which will then be sewn and delivered to the user, along with images, css files, js files ) I need to know how to create a fake container that will execute a JSP file (the process includes and evaluates the variables).

I read about using server filters to intercept JSP code output, but I'm not sure it will work, because: a) I need to create several HTML files and b) I need to display different content for the user (i.e. here ur zip file, upload it), not the output of the JSP being processed.

Thanks!

Here is an idea. Create a servlet to accept input from the user, from the servlet use java.net.HttpURLConnection to transfer the input to the JSP page and get the result.

URL urlPage = new URL(url);
HttpURLConnection conn = (HttpURLConnection)urlPage.openConnection();
conn.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));

//then loop through lines of webpage with br.readLine();

Then in your servlet you can pin all the files that you pull out and return them to the user

wget? , wget.

--input-file=FILE read URLs from file.

Using this parameter in wget, you will get a list of URLs from the file and load them for you in the same way that the text will be displayed in the browser-src viewer window.

Also wget is available for Windows and Linux.

You can also try using some of the many lightweight template templates that were designed specifically for this kind of work. This is what I did when I had a similar task, and never looked back. For example, Velocity .
