working on JSP since last 4 months

Hi,
I am sending this post out of frustation.
I am working on a project which is a porting from ASP technology to JSP. After conversion of ASP files to JSP files, I am now fixing the bugs. So I am more of in maintainence. The problem is I can debug a JSP or a Jscript file and fix the problems very fast ,but I don't have indepth knowlege of neither Jscript or JSP. I even can't code Jscript or JSP of my own. Because for the last 4 months I am fixing the bugs in JSP and I know java very well, I am able to solve any problem.
Can somebody suggest me what should be my approach and which is the best book to start with. I've already wasted my lot of time and I don't want to waste it any more.
Any suggestion will be helpful to me.
Thanks in advance
Shekhar
