Regular expression in java

http://java.sun.com/developer/technicalArticles/releases/1.4regex/

String input = "something";

1. write a regular expression

String regex="your_reg_ex"; 

2. create a pattern object compiling your regex

Pattern p = Pattern.compile(regex);

3. create a matcher object that will match input string with the compiled regex

Matcher m = p.matcher(input);

4. check whether any matching found

if (m.find())
{
//5. if found, the matched portion will be available at m.group()
String found = m.group();
// do whatever u like
 }

let, input = "fjkl;pokjhA123ss456Apghkit"
u want to read block between 2 A's
regex = (?<=X).*?(?=X) where X = "A" here output = "123ss456" u can only use fixed length string in (?<=X), never use .*? or + in X otherwise u'll get exception

Look-behind group does not have an obvious maximum length near index ..

Java code for this:

 
   String regularExp = "(?<=A).*?(?=A)";

 
   String input = "fjkl;pokjhA123ss456Apghkit";
 

   Pattern pattern = Pattern.compile(regularExp);

   
   Matcher matcher =  pattern.matcher(input);

      
      if(matcher.find())
         {

         String parsedData = matcher.group();
                 System.out.println(" Output ->"+parsedData);

          }

struts2+Spring workflow

1. An initial request goes to the Servlet container (such as Jetty or Resin) which is passed through a standard filter chain.

2. the required FilterDispatcher is called, which in turn consults the ActionMapper to determine if the request should invoke an action.


3. The ActionMapper interface provides a mapping between HTTP requests and action invocation requests and vice-versa.

When given an HttpServletRequest, the ActionMapper may return null if no action invocation request matches, or it may return an ActionMapping that describes an action invocation for the framework to try.

If the ActionMapper determines that an Action should be invoked, the FilterDispatcher delegates control to the ActionProxy.

4. The ActionProxy consults the framework Configuration Files manager (initialized from the struts.xml file).

5. the ActionProxy creates an ActionInvocation, which is responsible for the command pattern implementation. This includes invoking any Interceptors (the before clause) in advance of invoking the Action itself.

6. Once the Action returns, the ActionInvocation is responsible for looking up the proper result associated with the Action result code mapped in struts.xml.

7. The result is then executed, which often (but not always, as is the case for Action Chaining) involves a template written in JSP or FreeMarker to be rendered.


8. While rendering, the templates can use the Struts Tags provided by the framework.

9. All objects in this architecture (Actions, Results, Interceptors, and so forth) are created by an ObjectFactory.

This ObjectFactory is pluggable. We can provide our own ObjectFactory
A popular ObjectFactory implementation uses Spring as provided by the Spring Plugin.

Normally, in struts.xml you specify the class for each Action. When using the default SpringObjectFactory, the framework will ask Spring to create the Action and wire up dependencies as specified by the default auto-wire behavior.


10. Interceptors are executed again (in reverse order, calling the after clause).


11. Finally, the response returns through the filters configured in the web.xml.

The 5 stages of grief

1. Denial: The initial stage: "It can't be happening."
2. Anger: "Why ME? It's not fair!" (either referring to God, oneself, or anybody perceived, rightly or wrongly, as "responsible")
3. Bargaining: Now the grieving person may make bargains with God, asking, "If I do this, will you take away the loss?"
4. Depression: "I'm so sad, why bother with anything?"
5. Acceptance: "It's going to be OK."

1,100 reported killed in Bangladesh cyclone

Death toll may cross 1,000; all communications, utility services snapped; thousands missing; houses, crops, trees destroyed; lakhs homeless


Bangladesh dated with a nightmare as cyclone Sidr ripped through the southwestern coast late Thursday, killing over 700 people and demolishing houses, crops, vegetables and trees alike along its trail of devastation over an area of thousands of square kilometers.

Packing winds over 220km an hour, the fierce tropical storm roared across the shoreline after it hit landfall at the Khulna-Barisal coast at 7:30pm Thursday, cutting off all communications and utility services across the country.


One of the fiercest cyclones in the history of the land, the Sidr rode on wailing winds, driving rains and tidal surges to wreak havoc for over 14 hours before moving to Asam and Tripura through the Sylhet border, turning into a well-marked low yesterday.

Despite having carried out a commendable evacuation effort, the government last night found itself reeling from shock as the number of deaths and extent of damage continued to increase with every passing hour.

In a rather awkward manner, the food and disaster management ministry told the press in the afternoon that about 233 people were killed but left out death tolls in two most-affected districts--- Borguna and Jhalakathi. However, the same briefing stated that Red Crescent found 118 dead so far in Barguna alone.

But within hours at 12 midnight, an official at the food and disaster management ministry's control room raised the death figure to 700, with maximum 177 killed in Patuakhali. However, quoting unofficial sources, Our Correspondent in Patuakhali, reported death of 490 people.

But finds of newsmen and different private sources till filing of this report early morning today revealed that the death toll is destined to climb up to 1,000 as rescuers and volunteers could not yet reach most of the worst-hit areas.

Meanwhile, no information on causalities could be gathered from numerous remote islands (chars), residents of which mostly turned a deaf ear to government's evacuation alert.

“Tidal waves swept away many people from Dublar Char in Bagerhat”, Red Crescent worker Abul Kashem Dulal told our correspondent in Barisal. Of them, bodies of 17 people could be recovered.

The government could provide shelter for around 15 lakh people in 2168 shelter houses, leaving around 33 lakh people in the coastal areas in vulnerable situation.

Casualties apart, the Patuakhali district also suffered most in the farm sector. “The crop loss should be no less than Tk 497 crore in the seven upazilas,” he said, quoting a rough estimate of a deputy director of agriculture extension department in Patuakhali.

The Patuakhali town went under knee-deep waters as tidal surges 6-7 feet higher than normal ones sped through the locality. At least seven other southern districtsBarguna, Jhalakathi, Pirojpur, Bhola, Madaripur, Barisal and Bagerhat suffered nearly the same fate of Patuakhali.

However, the actual extent of destruction in Bagerhat could not be known till filing of this report as a very few could reach areas like Sharankhola near the worst-hit Sundarbans, the world's largest mangrove forest.

“Hundreds of trees lying on the roads and fields give a picture of massive damage,” said Raphael Palma, communications manager of World Vision Bangladesh, a non-government organisation.

Palma, who yesterday visited Mongla, said the locals are saying they lived through the cyclone of 1988 but it was no match to this cyclone. “The roaring wind was not as devastating as this one.”

The casualties could be much higher if not the local administration warned people about the imminent disaster, he observed.

As per the government count, 44 people died in Bagerhat. But unofficial sources put the number at 133, of which 90 were killed in Sharankhola upazila alone.

The volunteers and rescuers painted an even grimmer picture of the shocking event, which also left thousands injured. Chief Adviser Fakhruddin Ahmed too rushed to some southern districts in an effort to buck up the spirit of cyclone-victims.

But it will take weeks to assess the actual death toll, financial loss and days to reach relief to people who are forced to live overnight under the open sky, rescuers and volunteers said, almost in identical words.

People in lakhs are staying under the open sky with hardly any foods in their possession, thousand remained missing, embankments broke down in many areas, scores of livestock killed, and unknown number of persons was swept away by tidal surges.

However, the devastation could have been much higher if the cyclone, originally predicted to be heading for the shores of Orissa near Paradip, made landfall during the high tide hours at around 3:00am on Friday.

“Had the high tide and cyclone taken place at the same time the damage would have tripled,” said an expert.

According to the midnight update of the government, 177 were killed in Patuakhali, 134 in Pirojpur, 133 in Bagerhat, 78 in Barisal, 35 in Barguna, 32 in Jhlakathi, 25 in Gopalganj, 20 in Bhola, 15 in Shariatpur,12 in Khulna, 10 in Faridpur, four each in Chandpur and Dhaka, three in Sathkhira, one each in Laxmipur, Chittagong, and Jessore.

However, the government briefing in the afternoon stated 19 people were killed in Madaripur, two in Narayanganj, and one each in Noakhali and Chandpur.
