Are you presenting at any other Java user's groups in the near future? Some containers are starting to use XDoclet so you only have to deploy one, and the container does the rest. I would consider using JDO for dymanic queries. In the applications that I write I don't need to do many dynamic queries I usually try not to allow the end users to enter in SQL statements.
I am very happy with defining finder's and selects in the deployment descriptor. I find it very productive, and it is a lot less code than doing the same thing in JDO. I find JDO a bit cumbersome in the way it handles building queries.
And I've heard that argument before. An Entity can extend another, and it is nice to seperate the interface from the implementation. This is one of the advantages of JDO, but with this flexibility comes some added complexity.
Since Entity beans are in the container they are managed by the container, and they can notify of lifecycle events like ejbPostCreate. This is something that JDO is missing. JDO does not. You have to purchase it in addition to the container. We used it in production and it worked like a charm.
EJB QL is easy and allows you to naviage relationships easily. Of course we fixed the generator, but that's how I learned about EJB inheritance I don't currently have any plans that take me out your way, but I might be doing a web event for Empirix in November, and if I do I will cover some of the design pattern material I did for the book and at NEJUG. Keep an eye on my web site; I'll post details there soon. Ted, It was nice virtually meeting you. If I don't win your book, which I wont of course, I will buy it.
I checked out your website, and I see that you are in MA. Hi Rick, when i say entity beans are not meant to be real domain objects i mean the very nature of it i. Rick Hightower In the applications that I write I don't need to do many dynamic queries The only thing which i could visualize is this may not be the case with EJB 2. Rick Hightower wrote I find JDO a bit cumbersome in the way it handles building queries.
Here i would like to mention one more point, the entry point to a entity bean is the home interface, which is different for different entity-context whereas in case of JDO we have one single entry point the Persistence Manager.
Yes it does. Go to the following link The source code in this file has an Ant Script that runs XDoclet. This example works with WebLogic 7.
Your definition of a dynamic query may be different than mine. When I think of a dynamic query, I think of arbitrary SQL like select statements instead of precanned ones. It sounds like you are talking about cached data problems. Basically, I am not sure I understand you so I cannot respond very well. It gets a number of primary keys.
As you request the item, it loads it. Some containers can prefetch x amount. Can you explain how JDO would handle this better? Do we need to keep hepler dependent objects or i should put it this way whats the solution with EJB2. You showed up just in time for the waffles! And this tiny ad:. Boost this thread!
Entity Beans vs Value Objects. She's making eyes at me! This paper design and implement J2EE-based software testing cases management system. Through author used previous software testing cases management system when the internship of software test in SonyEricsson, summary of test experience and combination software requirements that collect from others.
This system achieves user login, software requirements, test cases library, test resources allocation, test case execution, problem management, test results statistical analysis for the seven modules. This system can create the intimate relationship among administrators, developers and testers and achieve the whole management of software testing and track the testing process.
