But it's perhabs still a bit too new to be used in real life?
Let's try it:
My setup:
- OS: Mac OS X (10.4.0) - macbook with 1.5 GB ram
- DB: MySQL 5. something
- Java: JDK 1.5
Step 1)
- Install JBoss seam and JBoss itself.
- I'm using:
- Jboss-4.2.2.GA
- JBoss-seam-2.0CR3
- MySQL
- Go to the seam home dir.
- Run the following set of commands:
./seam create-project
./seam generate-entities
What I got was a running application that could be opened in eclipse and Netbeans with EJB3 java classes, EntityHome classes, JSF views, editors and lists of all the entities in the database.
Good stuff:
- It is a really good starting point for a brand new application (if the database is build up front)
Problems I found:
- Whenever the tables in the database contains blobs or byte[] (bytearrays) it causes problems.
- The editors created disappointingly enough didn't make it possible to choose the "One" side in a ManyToOne relationship.
- The String based properties were all to be edited in a textarea.
- Why is it not possible to create views from existing EJB3 entities?
- Seams not to be a good idea to have to generate from a database if the EJB's are allready in place.
- What's the plans with seam-gen?
- Is it possible to generate-entities several times while working with an application without removing or overwriting added code?
- Where can I find a real life example of a running application. (Not the academic examples provided, but some real applications).
