I would like to implement charting and reporting module in my J2EE web application. I know there are many tools/technologies available like JasperReports , JFreeReport, jCharts ..ect. Please see more charts and reports tolls here.
Could anyone please suggest the best tool/technology which capable to handle reports and charts for large data?
Depends on your specific needs. For pure charting needs (as in drawing charts based on data), I'd use JFreeChart. If you are looking to have your data viewed in multiple formats (CSV, HTML, PDF) JFreeReport or Jasper may be a better fit.
Try Eclipse BIRT: http://www.eclipse.org/birt/phoenix/
"BIRT is an open source Eclipse-based reporting system that integrates with your Java/Java EE application to produce compelling reports."

There are lots of framework available in market but which framework should be used for fast development of java web application?
Additional to above, Many prefer combination of framework and JS library e.g. gwt/jquery+spring+hibernate; but which combination provide good performance of web application along with less time of web application development.
As far as i am concerned , the best J2EE Frameworks are
1.Spring as Applcication Developement Frame work
Hibernate for ORM
Struts for View
The main thing we have to remember is as an IT professional is don't dependent on any framework.You may need to work on the frame work u really don't know. But have the basic Java concepts in hand, which makes us adoptable to any J2EE framework

I want to make a tool for creating FSM control circuit simulations. NB! not the ALU part.
Can anyone recommend a good Java API with as much functionality already available as possible? Itll basically be something like a graphical modelling language editor.
The user should be able to make and run stuff like this:
There are a number of Java libraries out there for visualizing graphs. Some that I hear mentioned a lot include:
JUNG
jGraph
GraphVis and Grappa
The following blog has a pretty extensive list of options with commentary and screenshots: http://s6ai.livejournal.com/33969.html

How you do design composite webservices. Are there any frameworks available to let the developer simply concentrate on bussiness logic and to implement composite frameworks with some simple configuration.
I have read about SCA. But seems there is very less implementations of it.
Can some one suggest are there any frameworks which support ease of developing the composite webservices
An ESB caters this aspect to some extent. Please have a look at the open source WSO2 ESB built on top of Apache Synapse.
The WSO2 ESB comes with a large number of samples and please have a look at this sample too....
Thanks...

You can use iText.
iText PDF: your Java-PDF library
You can use iText to :
Serve PDF to a browser
Generate dynamic documents from XML files or databases
Use PDF's many interactive features
Add bookmarks, page numbers, watermarks, etc.
Split, concatenate, and manipulate PDF pages
Automate filling out of PDF forms
Add digital signatures to a PDF file
And much more...
Apache has a good library called PDFBox
Check out the documentation for the PDFMergeUtility
