JDBC again? not me. Really av been trying to do a bidirectional one to many relationship, is so Confusing using Hibernate, its not just giving me what i want, av tried using a join tables but when i save the entities the join table don't reflect it.av been trying to map Students and PhoneNumber. A student can have like zero or more phones u know, i can do it with representing the students id on the PhoneNumber table as a foreign key but that will lead me to HQL queries which m trying to avoid. Since am using an ORM tool i still believe that its possible to implement it elegantly cos an ORM tool should automate those tasks. may be i will check out ibatis, hope is fully complaint with JPA?

@candylips
pls which other options do we have currently?

I use Uniting testing when am doing enterprise java development with Spring framework, it gives you assurance that every part of your codes works as expected. its worth the extra time and energy cos it reduces the amount of time spend in debugging buggy app. i normally write test class for every class i develop to validate all my methods. You may not see the benefit when u write desktop apps and simple php websites but really when it comes to enterprise apps its a is extremely useful.

u can contact me 08060880402

@mikkyangel
  thank u very much for your timely reply. Y i decided decided the US was because of my university grades(3.4) anyway i might as well consider the pgd programe in Canada since most of the schools in the US has similar requirements. So how was your stay in the school? hope is worth it? as in the gains after the programme. please how easy is it to get a job as a software developer in that country? cos i will like to work for a while their and tap from professional before considering weather to do the Msc or come back to naija

hello house, i must commend the great job that u guys are doing by helping fellow Nigerians like us achieve our dreams of studying outside this country. Basically am a fresh graduate of Electrical Electronic Engineering thinking of furthering my studies in the US by doing a masters in computer science or information technology because basically am a computer programmer. So what i want to know is if its really possible to study and get a place of internship after study or during study in the US. Also i want to know schools that are affordable and within a nice and affordable state that do the courses i want to do. I have got some schools on my mind at the moment, Minnessota State university, University of texas-pan american and others. Also, i want to know how easy it is, to get scholarship that will aid me in paying the high cost of tuition in the states. Please house, i need your suggestions and advice on this matter, please if their are other Nigerians that have followed this path, i will like hear your take on this

2 me i will say that spring and hibernate are one of the best things that have happened to JEE, i cant remember when last i open a connection, got a statement object.

Anybody used these frameworks in developing enterprise level applications here? have read so much about these two technologies but have not heard of anybody using it or saying anything about those cool stuffs on nairaland. Does it mean we don't do enterprise application development here? or is it that u guys use another set of tools?. sha, i intend using them in a generic hotel management system next yr

Check a text book, dietel Java How To Program explains it well

ehen wats the problem? u jst wrote 3 classes with their respective constructors, and 2 of the classes are tied one to one relationship with the whole(Invoice), so wat do u wanna do with the code ?

U may try reading, initializing and putting all the vehicle objects into a list, u can remove any object u want from the list,then before the program terminates, u delete the previous file and write the remaining objects in the list into a new file with the same name and extension

May be u post d problem here or my email alaebo123@yahoo.com lets c if i can help u

U r welcome

@OP
am gonna give u a lil tip here.
from ur code it shows u r geting along well, but when reading from the command prompt. u need to read the input first, save it in a suitable variable, before u attempt to print it or do some tin else with it.

u can contact me will do it at a cheap price in php or jsp mail me at alaebo123@yahoo.com or call 08060880402

@prodam
am glad to hear that u are thinking in d same direction as me, this is my email address alaebo123@yahoo.com, i will give u call tonite lets discourse

Do u know OOP well ? if so u wont have a problem, think of the invoicing system as consisting of objects such as stocks, invoice, InvoiceLineitem, Sales, Customer etc. You will need a data store (example a database to help u persist ur domain objects, access will be OK), then with a good business logic and nice interface u will be done i no time, just java or Csharp will be better if u intend to develop for windows
OK start like this:
Use case Overview

1. what are your use cases ? what do u want the user to do with the app?
i. add item to stock
ii. view items in stock
iii.update item in stock
iv. add a new customer(if u decide to model the customer may be u want to keep track of your customers like opening a ledger for each customer it depends on the kind of business)
v.view daily sales
vi.view all customers(if u decide to model the customer)
vii. create invoice
viii. save invoice
ix.print receipt
x.refund customer his money
xi.etc,

Analyse your use case very  well so that u will discover some other requirements that the software will satisfy.


Design and implementation overview
From the use case, you will discover Classes with various methods and attributes, find a way to collaborate the various objects to achieve the various use cases specified.Confine each object to its particular duty example your InvoiceLineItem will have to calculate the price of each line in the invoice, while the invoice class which have a collection of InvoiceLineItem will take care of calculating the total price of all items, adding and removing item in the invoice etc. Your payment  object will have to take care of all payments and report back to tell the invoice Object if the customer has paid or not.before an invoice adds an item it has to confirm from the data store if the specified item and amount of quantity requested exist in the database, the invoice supplies the receipt object with information it will use to do the print receipt method, the invoice will have a save method that will use to call the data store object to update the records in the database to reflect the completed transaction,  the data store does all talking with the database and gives out public interfaces to client objects like invoice and sales object.
When designing, find ways of implementing polymorphism so that u can easily change your code codes if u want improvement in the future


the interface should be fairly simple with labels, text fields, combo box,Table,buttons Forms,dialogs to display errors etc,add button, remove button, commit transaction button,print receipt,Refund form with text fields and buttons etc

create a database of tables like Stocks,Sales,refunds

finally test your codes to make sure it perfectly satisfy your use case requirements.

thanks for ur reply, is not as if i cant prove myself when it comes to getting the work done. But, av not really worked in nigeria all i do is side projects for myself and few clients that i have developed websites for. As i have graduated from school, i need to go into serious programming, right now i have not got any certificate that i will use to convince an employer that this is what i do, before presenting my archive of works that i have done.

Fellow programmmers, am still waiting for your replies o.

Hello programmers,
Am a young graduate trying to enter into the labour market, pls what is the hottest programming certification that can help me land a job in lagos, already i have intermediate skills in java and csharp.pls ur replies will be well appreciated.

I tire for this country self, @OP na 12k website you go use marry, buy good ride?

Will take 180k, it will take 6weeks am a core programmer i will have to contract a very good designer for a professional graphic, the site will be built with jsp, jquery, hibernate. it will be built to be easily extensible by any programmer with relevant java skills. call me with 08060880402 or mail me[email]alaebo123@yahoo.com[/email]
