I am kind of curious, which topics are giving (had given) you the worse headache?
What is (was) your nightmare? When did you think like � I really don�t understand this�?
Please list top three topics.

For me my biggest headache was custom tags so:
1) Creating your own Custom Tags (everything involved in that)
2) Using Custom tags (return values for each method etc
3) Not really sure... did I mention custom tags?

Remembering the web.xml deployment descriptor elements. It gets trickier when some tags don't have a '-' unlike most others
What comes after what is easy, but complex levels of nesting and the optional elements/attributes drove me crazy. The DTD is not as intuitive as a Schema description. I hope Sun starts using a Schema soon instead of the DTD.

web.xml. It took a while to see the connections of security in Servlet, security-constraint, and security roles. Then the next toughest thing is to get the order of the dtd correct. Man, that's tough. I also had some time understanding custom tags, and what each of the Constants meant, and who could return them.

still taglibs. Perhaps if one looks at some existing taglibs like for example apache.jakarta.taglibs things will get clearer.
You can learn the concepts. Its not that dificult. But still I desist to use them in my own small apps, because for me its dificult to design them. There is too much scriptlet code in my own app.

as far as i'm concerned, EVERYTHING is difficult just kidding..
but seriously i think design patterns r difficult to assimilate as i guess one requires experience with designing lot of servlets and applications in which u come across tradeoffs and benefits along with appropriateness of each design pattern...
one cant really create examples on his/her own to apply patterns. it is something which gets woven into ur mind after considerable battle with practical situations encountered thru experience...
just my 1.99 cents!

a) Thread-safe applications. Rules are easy but understanding the container management of jsp implementation classes behind that is a little tricky.
b) ServletContext and its listeners.
c) Session management. This was a bit difficult as I have no real-world experience of needing/using sessions.

For me it was session management with Cookies and URL rewriting...
