request.getPathInfo() vs request.getServletPath()

[Alexander Sales]

In using the following methods.

request.getPathInfo()

request.getServletPath()



Is it possible to get both Paths?

How does the two methods work according to your experience?

Thanks,
Alex Sales

The javadoc can be useful

They each give different parts of the URL. And yes, you can use both. Why would you not be able to?

[Alexander Sales]

Oh.. I had a mistake while testing them..

but I noticed...

request.getPathInfo() - becomes null when I don't use wildcards in the url pattern.

request.getServletPath() - becomes empty when you use a url pattern name of a servlet like - '/index.jsp' or '/*'.
but will have a name if it is written like this - '/anyServletName/index.jsp' or '/anyServletName/*'.
it will output - '/anyServletName'.

From the javadoc
getServletPath : Returns the part of the request's URL that calls the servlet. This includes either the servlet name or a path to the servlet, but does not include any extra path information or a query string.

That's why getServletPath() for '/index.jsp' or '/*' returns null, that's because these urls do not call explicitly the servlet.
On the other hand '/anyServletName/index.jsp' or '/anyServletName/* call explicitly your servlet that's why getServletPath() returns something
