Reading File

[Jose Mon]

Hi,
I want to read a jsp frile from a servlet. My Jsp is in the root directory of the web application. By giving what path, I can access that file.

[A Kumar]

is it just reading the file or transferring the request execution to the jsp...

If its reading then
you can use getResourceAsStream()

I want to read the contents. Noe it is showing FileNotFoundException.
How should I give the path. Let my jsp is WebContent/Jsps/hellop.jsp where WebContent is the root of application

[Vikrant Pandit]

Try using

getResourceAsStream("/Jsps/hellop.jsp")

If the jsp is in the context then try

getResourceAsStream("/hellop.jsp")

Its a method from servlet context.

InputStream in = getServletContext().getResourceAsStream("/hellop.jsp");

I think you can read it using a File or FileReader class. But first you need to get the path to your JSP files, and this can be done by getting the path from the servlet context.

getServletContext().getRealPath("/foobar.jsp");

If the file exists within the structure of the web app, using FileReader with getRealPath is a poor (or, at least, non-portable) choice.

getRealPath returns null if your application has been deployed as a packed war file. Using getResourceAsStream works the same way whether the app has been deployed as a packed war file or as an expanded file system.
