Hi friends, I would like to have some experience with J2EE development using freely available resources. The big constraint is , I have only win98 OS. Thinking of converting a web appln which is written using MVC model (servlets,jsp,javabeans) as J2EE appln. I download Ed Roman's book and read initial few chapters. Tried to installed Sun's 'Reference implementation'. But couldn't succeed in deploying those examples outlined in Developer's Guide using Sun's Deploy tool. So thinking of going for some other J2EE server (orien/WebLogic If you have some idea of this learning process , please post them. Thanks a lot. regds maha anna
Hi Maha, It great to hear from you that you will march to the J2EE and EJB field. In my oponion, the followings are the best resources for learning EJB: 1.You can find the EJB tutorial on javasoft.com http://java.sun.com/products/ejb/?frontpage-javaplatform 2.You can download Weblogic 5.1 for 30day trial from BEA website and install it on your machine 3.You can download the full document and examples of Weblogic 5.1 from BEA website -- it's great doc and examples 4.You can borrow or buy one book named Enterprise JavaBeans authored by one EJB Guru - Richard Monson-Haefel These are all rush in my mind now. Hope the information will help you.
The J2EE blue prints on the java site along with the pet store example are a great introduction to J2EE technology and how to design an application. Before converting an application read through this material and it will give you tons of insight. All the best

Thanks Liu and Lancy! Downloaded the PetStore BluePrint Zip. Recently attended Sun's Tech days conference in Raleigh, NC and atteneded the session on 'Developing Enterprice Applications using J2EE' technology. Planning to go through the appln and get a hang of it. For the development and deployment , I think I go for the 30 day trial of WebLogic since it seems to be good implementation of J2EE spec. I would also be eager to know others experinece with J2EE technology. regds maha anna [This message has been edited by maha anna (edited May 01, 2001).]
When the 30 days are over, Orion and jBoss are nice EJB servers to use. Orion is a commercial all-in-one server (web, servlets, and EJBs), written in Java, with free developer's licenses. It will work fine on Win98 and isn't too much of a resource hog, comparatively speaking. The documentation is gradually getting there. There is some helpful tutorial material (which is worth reading no matter what app server you use), and the deployment tools provided mean you won't have to muck with XML configuration files for a while. jBoss is an open source effort. Although I don't have nearly as much experience with it as I have with Orion, it seems very interesting from a technical point of view, and the development is pretty well managed. jBoss is my best bet to become the Apache of EJBs. Documentation is a sensitive point though. If you try it, be sure to download one of the versions that come with a servlet engine as jBoss is a pure EJB container. Personally, when I first got into J2EE and EJBs, I found configuration and deployment the toughest nut to crack. Probably makes sense given that EJBs are an effort to shovel as much responsibility into the container as practical, and all that stuff has to be configured. Have fun! - Peter
