If you implemented any of the suggested exercises, you extended it
even further and learned more about DWR in the process.
In the next chapter, we??™ll implement another extremely useful application, namely a file
manager, and we??™ll see how DWR can make such a thing work quite a bit like the file manager
you are probably used to in your native operating system.
CHAPTER 5 n SHARE YOUR KNOWLEDGE: DWIKI, THE DWR-BASED WIKI 258
Remotely Managing Your Files:
DWR File Manager
Imagine you have a nice, fast, fat pipe to your house (get your mind out of the gutter right
now!!). You would love to be able to set yourself up a server that you could access from anywhere
on which you could keep your files. Further imagine that you??™d like to have something
akin to Windows Explorer available to you, a relatively basic file manager that would allow you
to mess around with those files on that server at will.
Well, with the help of DWR, some nifty UI components, and some very handy utility
libraries, that??™s exactly what we??™ll be building in this chapter! We??™re going to cover the basics
that you??™d expect to find in a file manager, and perhaps one or two things beyond that. We??™ll
use DWR to connect the user interface with the server-based components as we??™ve seen
before, and we??™ll also put some decent security on top of this, given how dangerous such an
application could obviously be.
