What is the need of a reporting server?
What do I miss out by not using a reporting server and instead using a reporting library?
Reporting libraries like Jasper can easily generate a report and can be embedded anywhere, be that Servlet or a desktop application. Why then would one need a reporting server?
The most useful feature of a reporting server would be the ability to generate scheduled reports, the second most useful is the ability to view reports on the web, aside from that, you don't miss too much if you don't use it.
A reporting server usually generates reports offline or cached on demand. This means that report you need are more likely to be pregenerated and accessible immediately rather than waiting for the report to generate. It can also be used to generate reports which are emailed periodically.

I have to write an automated script in Java to do following
Login to an internal website with userid and password
Once login is complete click on a link which will open another web application and make sure the website is available
Send success / failure email to a specified group
The above job will have to run every day at a specified time to check the site availability. (I can use windows scheduler to schedule this as a job)
Due to network policy I cannot use any site availability websites to check this.
There are lot of Java based test frameworks available in market.
I would appreciate if anyone can point me to the right framework.
Thanks
Selenium Web-Driver Automation framework is the best. It supports multiple langugaes, along with Java. You can check the seleniumorg site http://seleniumhq.org/
For mailing, you can use Java Mail API.

I am building a mid-sized standalone console based java application and I must log various events that can take place. I am not sure about which API to use. I have looked upon Logback Project and log4j. I am concerned if these are the right one, since both of the seem to have extensive uses in the web application projects. Please help me decide if I am better using the default java.util.logging API or should I use another frameworks; if so which one.
Thanks!
I recommend slf4j.(it's written by the same guy who did log4j) You can read more from here

I need to create SOAP web service without using some web server(apache, jetty, ...).
javax.jws.WebService seems best option, but I know how it work in production mode.
Someone using javax.jws.WebService? It will be work with 100 online users?
Maybe some advise about other web service options?
Thanks!
It can easily support 100 users, rather you will need to make it support 100 users ;)
You can implement the webservice without webservers but then you will end up coding all the features that the webserver's provide to you like:
-- Multiple request processing or scalability
-- Authentication, authorization, auditing.
I you could tell me why do you want to hand code the webservice platform it would be helpful.
Some WebServers can run in embedded mode (jetty for example).

I am writing code that often has to work in restricted environment. I sometimes code at home, where it works nicely and the moment I put it to test at work, McAfee or some other firewall blocks it.
Sometimes it is not possible to disable such protection.
I need a test suite for my home development environment where I can simulate all these restrictions without having to install all of them myself (for instance it is my experience that it is very hard/impossible to clean all traces of mcafee once you have installed it). I also need to simulate proxy servers.
I am writing code in Java if it helps.
[EDIT: so some Java library for this would be great]
You could use VMware (or VirtualBox) with different test-setups.
Try node.js. Also have a look at a sample proxy implementation

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."
