OPEC vs Shale

This picture is almost correct explanation for today's (29-November-2014) three years low oil prize i.e 72$ from 115$.
OPEC (Organization of the Petroleum Exporting Countries) is group of Oil producing countries and logically they includes Arab countries and some African countries. OPEC provides forum to oil producing countries to lower/increase oil production and oil prizes.In seventies it had dominance of foreign oil companies but later God given sense to Oil  producing countries government and now they have dominance(just to say). Though OPEC decides oil prizes and extraction , but it's acceptance depends on will of it's members.
               Now you will understand that in Seventies Oil Crisis had happened because OPEC countries had put oil supply limited in practical term it is called embargo.So all oil consuming countries mainly US at that time (now position is replaced by India,china) stumbled for oil and their economy had collapsed.In simple term their economy had almost paused.So from that day US decided that their policies should be designed so that to reduce oil dependency and they had put money from oil alternative research and they found shale gas. Now US uses 20% shale gas and they have target up to 80% in 2015 and complete oil independent in 2050.
            Now you understood  complete background (I hope!). Now look at picture and you will understand complete picture and its relevance to today's low Oil prize situation. Frankly , I took this picture from Economic Times.

So you may ask question why are we paying same prize on petrol in India though it is deregulated?
           Yes , international petrol prize has reduced and our (Indian) government also made petrol deregulated means its prizes are linked to market prize and government has no control over petrol prizing.
          But yet we are paying almost same rupee for petrol because government increased excise tax on petrol. Government made statement when increasing excise duty that this increase is to cover earlier subsidy gap. But in economic sense this increase is good for us.
          If we get low price petrol , we will opt other alternatives and we may increase dependency on petrol and off-course it is not good for economy and environment. It will put us in crisis in future when again oil gains its prize.

Share data between Iframe and its Parent using JQuery

There could be requirement that you have to pass variables values to Iframe from parent or in other scenario you have to pass values from Iframe to its parent.I am going to show simple example of above situation with the help of JQuery.

Spring Default Limit for Collection and Array is 256

If you are working in Web Application Development then you may stuck or already had ,then you will get mad of getting this error

How this error emanates in Spring?

i will explain you with example.Suppose you are adding Values in List in JSP using JSTL tag or other.
This list is in Form(HTML).When you POST this form,In behind Stage,Spring does binding of Object and List if present.

But wait...
In Spring,Default limit for array and collection growing is 256.

Why this limit is Set?

seldom you have to send List size greater than this limit.
Spring has set this limit to avoid notable OutOfMemoryErrors in case of large indexes.

So,than What if i want to set Collection greater than this size?

I had told earlier,spring does binding behind.If we tell spring to increase it's size or set collection size behalf of spring.
You you can do it.

We have initBinder,  in Spring  it is called when spring does the binding mechanism
e.g @Mod…

Apache FOP Tutorial for PDF Generation

What is meant by Apache FOP?

Apache is providing open source JAVA application for PDF(or any other format) file generation from XML data.Simply to can give data in XML,it gives output in PDF or any format.But it is primary for PDF output.

Official explanation,
OP (Formatting Objects Processor) is the world's first print formatter driven by XSL formatting objects (XSL-FO) and the world's first output independent formatter. It is a Java application that reads a formatting object (FO) tree and renders the resulting pages to a specified output. Output formats currently supported include PDF, PCL, PS, SVG, XML (area tree representation), Print, AWT, MIF and TXT

How wcan configure apache fop with our project?

I am going to explain how to generate PDF using Apache FOP.
I will explain it in steps

Step 1:
You will require 3 jar for configurations.Here fop jar depend on both avalon api and avalon impl.
              1.    apache fop 1.1
              2.    avalon-framework-api 4.3.1
