Problem with ServletContext.getResource()

Hi,

 

I want to write to a file. I use the following method:

 

String contextPath =
cycle.getRequestContext().getRequest().getContextPath();

ServletContext context =
cycle.getRequestContext().getServlet().getServletContext();

String somefile = contextPath +"abc.zip";

String outFileName = context.getResource(somfile).getFile();

 

This return a null value for context.getResource(somfile). I tried
getRealPath(), it worked, but it was deprecated. Anybody knows what the
problem is here? Or there are some other better ways? 

 

Many Thanks.

 

Henry

Try:

String somefile = "/abc.zip";
//String outFileName = context.getResource(somfile).getFile();
String outFileName = context.getRealPath(somfile);

As you're trying to write to the file, you can't use getResource(). 
Instead, use getRealPath(). I don't know why you think getRealPath() 
is deprecated.

This doesn't work. Even getResource(contextPath) doesn't work.

Could it be:

String somefile = contextPath + File.separator + "abc.zip";

or about the same:

String somefile = contextPath +"/abc.zip";
