This is regarding the feasibility of adding my own plugins to Eclipse. I know Eclipse is the Open Source. I want to add some plugins to Eclipse. For that What are things to be known? that is, In what are all the areas (technically) one should be very strong? Where can I get more support in this work?
Obviously you need to know J2SE programming, and you need to know Eclipse fairly well. Beyond that, you almost certainly will need one or more of the fine books about Eclipse plugin programming. Three I own and would recommend are reviewed here, here, and here.
I have some work experience in Core Java, Servlets, JSP and Struts.. But I have now only started working some projects in Eclipse. So I don't have indepth knowledge in it... So, before I start working on plugin development with the help of books mentioned by you, it is required to get/learn some books on eclipse..
If so,please suggest some good books on eclipse(with Java) for beginners...
The Eclipse PDE (Plugin Development Environment) comes with some good documentation in the Eclipse Help. On the Eclipse site there are also some good getting started tutorials. Make sure that you also have the sources for Eclipse, that way you can easily look up examples (using the Search) and references for methods/classes. Great way to see how they do things.
