Hello reverened authors and wrox-staff,
Hope the following thing may tend you to advance your help in as much as I always wish to forward my advance thanks.
Your fourthchapter is rather very motivating as i see a nice panel versions being well explained however read this in order to enable your help in what I requst
**********************
In the recent days of sports surrounded world it becomes essential to classify the Cricketing world into in its own dominion.
As for example an amateured cricket captain would be requiring a ready made interacting tutor to initially help him to set the fielding arranements for his bowlers.This is a very begining stage for such a task since so far no one has initiated such a trend though advanced method of third umpiring system has alreaedy been made available.
I thereforefore need someone to suggest a best pattern for making the captain happy by way of stand-alone application in web and later to transform it in mobile as well.(since embedding system and link it to 4th chater panel programs is new for the book)
Is it a possible one or not.?
If yest why not use use the following classes to initiate a setup method,to start with later with recurring methods and probability methods to quickly arrange in a nutshell for the cricket captain in his field arrangement)and so on..
1)Bowling calss
2)Batting class
3)Fielding class
each which to have its own variables

As a general example

FieldClass can have Inner field(First sli,Second slip,gally etc)
and
Outer field can have (longonlongoff,deepfineleg,midwwicketetc)
for a spcified type of bowler(leggspinner,offspinner fast bowler etc)

In the event of this task becoming full and made useful
which is definitey will be a first of its kind
Advance Thanks for the pattern suggestion
If not a suggestion a suggestion how do i initiate using 4th chater
and maqke a jar file till such time i get embedded type finally from you
Thanks

Hello
Can any one help to let me know why a jar fle that i created using jar option,invariably tells that jar is unable to load my manifest file.
What coud be the possible errors for this kind of trouble in the opening of a jar file .Also tell about serialisation of variables that i use in the appl,if it has a negative trend,in case of its (seralisation) not implemented for the appl program before making a jar .
Advance Thanks

The following Code in java (an application Prog)
needs to be jarred.though the try out by jartool is not possible since this prog requires class files and a manifest file along with src.
If the attachment forwarding is enabled by authors a zip file can be forwarded by which you can help me to create the jar file .Please reply soonThanks
