Validating Web.xml file

While working with java web application development often we need to install applications again and again on web server / application server. And often when we deploy application after modification to web.xml application fails to get deployed giving long error in Tomcat ( or any other server) console.

To check validation of web.xml before deploying we can validate it with standard web.xml dtd

I used ant to handle deployment / stopping / starting application in tomcat.

You can use the following ant task to check validation of web.xml

<dtd publicId="-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"

location="web-app_3_0.dtd"/>

</xmlvalidate>

</target>

You can make compilation target dependent on checkwebxml task so that compilation and deployment doesn't starts before validation of web.xml

This will ease our task to find error in tomcat console when we try to deploy our application

UPSC Civil services 2011 Preliminary Exam Paper 2 Answers

UPSC 2011 Civil Services Preliminary Exam Analysis

Just came after giving exam for UPSC Civils 2011

Here are my personal thoughts ( PS : I am not any expert , there are just my own views)

Paper 1

Total questions were 100 , time was 2 hours

Gone are those days when exams were full of Indian history , i feel UPSC has moved on and now they are testing us for current events. People who read papers like The Hindu and Frontline magazine should feel they are on right track to prepare for exam like this. Paper was logical and nothing like what happened in year xxxx bla bla types questions.

Current affairs , geography , economics topics of inflation and banking were tested often.

Paper 2

Total questions were 80 , time was 2 hours

It was exam with lots of English questions . Frankly i was astonished to see so many English passages. I don’t know what was in paper setters mind.

8 questions in the end which didn’t not have negative marking were testing Decision making skills

Maths questions were typical RS agarwal types , you just need to brush up few formulas to solve them

What will be my score ?

Seriously i don’t know , exam would be high scoring i feel. People who are preparing for it religiously for this since long would easily crack it.

What are your thoughts? Please post
