If you are wanting this for nice dynamic pages, I would read a book on
Java and then read the nicely organized webojects manual that comes
with 5.2. The best analogy I can give from php is this.
In php when you want to call and do something with Mysql, you need to
do everything. Open database, select what you want then apply the
results to the a page.
With webobjects and the EOM Modeler, you create the structure of the
database (in EOM Modeler). Then you tell EOM to create the tables and
rows in Mysql (or read the existing structure of a database and store
in as a EOM file). Once this is done, you can now add the EOM model to
your project (WO application). Because the model matches the structure
of your database, WO can now include talking to the database. The best
example of how this works is using Dreamweaver php/mysql dynamic pages.
You set up the connection (in WO terms this would be configuring the
EOM Modeler and setting up the tables and connect, as well as the
adapter and adding this to your WO project). In Dreamweaver, you can
see all the fields in the database and add ie a repeating region. The
idea in very similiar with WO but all the coding is either done in Java
or through the use of xml style tags that your application fills when
delivering the page as the application runs on the server.
Because all the customized coding is done in Java, knowing it is
completely invaluable. Similiar to using Dreamweaver and the dynamic
pages but not knowing php. If you want to tweak something, you code it
and be done with it. In both if you do not know the native language,
tweaking becomes impossible.
If you get a grip on Java 2.0 and spend most of your time on the
principles of OOP, like classes, methods, implementation, extending...
you can look at the examples in the Apple manual and the pieces should
fall into place. This means you need not read much on JDBC since WO
handles most of that stuff for you, again unless you want to do
something customized.
I have all the current books from third parties and the Apple manual
does the best job cruising you into getting started. (that is my own
opinion and did migrate from php and mysql as you mention you are
doing) My biggest leap was to understand how the parts of webobjects
fall together to build a page and where I need to code in Java for
certain pieces of the page.

hello,
I am a brand new WO user. Currently I am using PHP/MySQL combination.
Is there any good resource on line where i can get a comprehensive
information/tutorials about WO5.2 and learning Java?
All I could find is out of date...
Thanx for help
