How to get resources from our web-app context ?
Dear all,
In my wicket apps, I have a use case to read a file that is located in
my web-app context. How do I do this in wicket?
Thanks in advance,

this is what spec says
getRealPath
public java.lang.String *getRealPath*(java.lang.String path)
Returns a String containing the real path for a given virtual path. For
example, the path "/index.html" returns the absolute file path on the
server's filesystem would be served by a request for "
http://host/contextPath/index.html", where contextPath is the context path
of this ServletContext..
The real path returned will be in a form appropriate to the computer and
operating system on which the servlet container is running, including the
proper path separators. This method returns null if the servlet container
cannot translate the virtual path to a real path for any reason (such as
when the content is being made available from a .war archive).
*Parameters:*path - a String specifying a virtual path*Returns:*a
Stringspecifying the real path, or null if the translation cannot be
performedSo
if the file is with in your context, then you should be able to get it using
the getRealPath(), if it's out side then you will have to specify the
absolute path.
I am not sure if there is any other way around

Yeah,
It doesn't work with ServletContext.getRealPath("").
I have a template.vm that is located under my web-app context and I
want to read that file from wicket. But since Servlet is not exposed
direclty, I don't know how to do this in wicket.
Thanks in advance,

can't use ServletContext.getRealPath("") to get the actual file path and
read the file as you read normally.
getServletContext() method will return the ServletContext.
Or are you looking for something different ?

Hi Joshua,
In a page
ServletContext context = ((WebApplication)
getApplication()).getServletContext();
File reportFile = new File(context.getRealPath("/reports/myReport.jasper"));
under webapp put a reports folder
You can use every file / image / whatever
HTH
