Hi,

I have a jsp file called behind the scenes by a client html file.

The jsp page has to load an xml file which is in the same directory as the jsp page.

The only way i can get it to load is when i put the full windows path.

I use

 File thefile = new File("Thexml.xml"); //does not work

 File thefile = new File(http://correctpathtofilewhichworksinbrowser); //does not work.

File thefile = new File("../directoryabove/xmlfile.xml"); //does not work.


The only way that works is

File thefile = new File( "c:\\pathtofile");

Thanks.

TimYates post should work, but one thing to consider - the reason you are having to put the full path in is because the relative URL is from the web server executable. For example, even though your site may be in the folder 'mySites', as far as java is concerned, your running the program from the application servers root directory, and so this location is your relative path.

Doesnt help you, but this is why your getting this result.

I had to use colr technique, so made sure i could map to the correct directory once i knew where i was.
I couldn't get the

new File( getServletContext().getRealPath( "/xmlfile.xml" ) ) ;

to work even when importing javax.* at the start of my jsp.

Thanks.

You shouldn't have needed to import anything...

especially not javax.* which doesn't import any classes (there is nothing inside javax.*)

The only problem with that method is that it isnt portable. In most cases this wont be a problem, but good to know.
