Hi Rizwan,
Nowhere in HFS/J?
I can't be sure about that.
Simply speaking, Filters are a prime example of what servlet chaining is all about.
You can google "servlet chaining" and will find lotta links on this.
You get the idea.
I don't think that servlet chaining has been really elaborated for the SCWCD exam.
The most important aspect of it, Filters have been really elaborated for the SCWCD......
