public class ServletContextResource
Resource implementation for ServletContext resources, interpreting relative paths within the web application root directory.
Always supports stream access and URL access, but only allows
java.io.File
access when the web application archive
is expanded.

Method Summary | |
---|---|
Resource |
createRelative(String relativePath)
This implementation creates a ServletContextResource, applying the given path relative to the path of the underlying file of this resource descriptor. |
boolean |
equals(Object obj)
This implementation compares the underlying ServletContext resource locations. |
String |
getDescription()
This implementation returns a description that includes the ServletContext resource location. |
File |
getFile()
This implementation delegates to ServletContext.getRealPath ,
but throws a FileNotFoundException if not found or not resolvable. |
String |
getFilename()
This implementation returns the name of the file that this ServletContext resource refers to. |
InputStream |
getInputStream()
This implementation delegates to ServletContext.getResourceAsStream ,
but throws a FileNotFoundException if no resource found. |
String |
getPath()
Return the path for this resource. |
ServletContext |
getServletContext()
Return the ServletContext for this resource. |
URL |
getURL()
This implementation delegates to ServletContext.getResource ,
but throws a FileNotFoundException if no resource found. |
int |
hashCode()
This implementation returns the hash code of the underlying ServletContext resource location. |

public ServletContextResource(ServletContext servletContext, String path)
The Servlet spec requires that resource paths start with a slash, even if many containers accept paths without leading slash too. Consequently, the given path will be prepended with a slash if it doesn't already start with one.
