Hello world,
I am very new to J2EE, but I am ok with JAVA J2SE. I have written a swing program which is a stock controlling and billing system. In that program I have these facilities.
It is possible to add new Item details, delete them and update the item details.
Can add new Suppliers, delete the supplier details and update/modify supplier details.
Have debtors which I can add, delete, and modify.
Have Users which the user can add,delete, and modify.
Have a billing interface where the user can select an item and enter the quantity which the customer wants to buy and generate a bill.
I want to do the same program with EJB. I am not getting paid for this and I am doing this for the fun of it. There is no dead line for the project too. So time is not a big probelm to me.
I just want to know what do I have to do before I start this project. I have read 'Mastering EJB' by ED ROMMAN. I have JBOSS server, eclips, J2EE ..
I would be really greatfull if you can give me a plan to do this.
Thank you very much.....

Hi Ransika,
I see you are using all the free stuff. I understand that. I am not proficient with those tools. I get to use the expensive stuff. But if you are up for it, try downloading the evaluation copy of WebSphere Studio Aplication Developer from IBM. It is free for your evaluation and will work for 60 days. It is rather large and there is a learning curve for sure. But it makes doing the J2EE development so much easier, with the built in WebSphere Test Environment. The built-in help is excellent, and there are also excellent free resources on IBM's web site. You would probably think I am an IBM employee, but I am not. I just like their stuff alot.
Regards,

I wouldn't go the WebSphere route - it's a pain (esp. with the pricing!) - use JBoss.
I would start by modeling the project using use-cases, then basic class diagrams. Draw a couple sequences, and really understand the design before you start. If you try to dive into code you'll be doing and re-doing for the rest of your life!
Based on your post, it looks like your use-cases are pretty well laid out. Given that the app exists, the database must exist as well, so moving onto an EJB model should be pretty easy.
Drop me an email and I'll be more than happy to help. I'm always picking up small help-projects like this.
