I want to write image file to directory : WebContent/images,but it always comes the error:FileNotFoundException.Anyone who has a demo about this problem?

Are you really sure you want to write to your application server in stead of a fileserver?

Although i would like to make the same question as chill says, i think you can get the web folder's real path doing something like this:

import javax.servlet.ServletContext;
....
....
ServletContext servletContext = (ServletContext)Executions.getCurrent()
                                                          .getDesktop()
                                                          .getWebApp()
                                                          .getServletContext();
File f = new File(  servletContext.getRealPath("/images/") );

hope that helps

Hello stanley1991,

Please read also this post which explains why you should not do it, but also presents an alternative method to solve your problem.

Best Regards,

Using the method that @cyiannoulis recommended above will write image file to the real path of tomcat running instance but not the path in webcontent in Eclipse.Currently I accept his answer because I cann't find better one so far.
