Subject Re: Cayenne vs JPA tools
Date Sun, 25 Feb 2007 16:24:20 GMT
I am using Hibernate in the work, and I worked long time with EOF and some 
time with Cayenne.
You are right, Cayenne or EOF have the GUI Tool which helps much. On the 
other hand, There is for example an Eclipse plugin which creates the mapping 
files for Hibernate.

However, I think this is not the problem. I saw this problem also when i 
started working with hibernate. I was wondering and searching for the GUI 
appliction to build the mappinf files for Hibernate.
In the real life this is a minor Problem.

Check which tool is the best for your application and which features you 
need. Of course you cant forget also the advantage of using Cayenne, that it 
is very very simialr to EOF. And if you know EOF, you need couple of days to 
use it. With Hibernate you will need more than couple of weeks to understand 
what the hill this tool does :) (In good way of course)

Hope this helps you.
