OJB

[Mi...@iff.fraunhofer.de]

Hello,
I'm new in JDO and OJB. I tried to configure the ojb Implementation with 
Eclipse...but there where several errors. Do i need every jar file in the 
lib-folder? Can you perhaps describe what i have to do to get ojb working? 
I also tried to use the tutorial on your hp but i don't kno how to enhance 
and to generate the schema... I have the following folders...
 
ojb --> project root in Eclipse
src --> here are my sources ( 2 classes: Product and Book...and one 
test.class)
lib --> here are all jars from the the ojb framework..
target\classes --> here are the compiled class files and my *.jdo File
I have to use this folder structure it is defined in this way.
How can i now enhance the class files for example over command line or an 
ant script laying in the root folder (ojb)?? I don't need to compile the 
classes, because eclipse does this work for me. The same question comes on 
generating the schema for the database...i use mysql and oracle as 
dbms...perhaps is it possibler to send me a description on how i get the 
classes enhanced and the database schema created...
Can you help me please?
 
Many thx...
 
Michael

You will find everything you need under:

http://db.apache.org/ojb/docu/index.html

There are lots of things to learn before you find ojb easy to use.

First, you should use the ojb-blank.jar available from the binary 
download section. It contains a ready-to-start project (including 
Eclipse project files) complete with all necessary libraries, XDoclet 
OJB support and an Ant script.
Then, have a look into the Getting Started doc 
(http://db.apache.org/ojb/docu/getting-started.html) which explains the 
various files in the ojb-blank. Also, the tutorial 5 deals with JDO, so 
it should be worth a look.
Finally, in the build.xml of the ojb-blank project there is a sample 
target for enhancing a class (from tutorial 5) for JDO. Due to the way 
this is done, we cannot easily provide a generic Ant target for this, so 
you have to adapt this target to your project.

Tom
