How can you be programming JSP's/Servlets without any knowledge of object
oriented concepts and design? Unless you learned those concepts first by
programming in pure Java, and bypassed learning C++. If not, I'm not
surprised that you are having some difficulties. It sounds like your
employer has tossed you into two competing technologies (JSP/Java, ASP/COM)
without the proper background or training to understand either. And a
background in C will not help you in either of these two technologies.
The microsoft web site has some of the best info, along with journals such
as the VB Programmers Journal. MS site can be found at
http://www.microsoft.com/com/tech/DCOM.asp. I will forwarn you that not
having a background in object oriented concepts and design (such as C++ or
Java) will make it difficult if you learn COM or DCOM, and then move over to
JSP/Servlets/Java or C++. The concepts in Com/DCOM, in my opinion, are not
transferable into other technologies (with the possible exception of CORBA).
In addition, Com/DCOM will be deprecated by MS when the .NET platform is
released in it's final form, which is suppose to happen by the end of the
year. So I would not waste a lot of time learning a technology that will be
outdated by the end of this year. I would really focus my time on learning
JSP/servlets, how to create Java class objects (beans), and OO concepts.

Thanks for your insight, Celeste. I don't have much knowledge of C++, though
I know C. Could you please point me to some resources on COM/DCOM and
ActiveX.
Thanks
Rohit.
