[Sorry, this is off-topic. I just want to tap into the knowledge pool
in this list. Please feel free to ignore.]
Three probably basic questions:
1. I need to process XML files having this shape:
<data>
<record>
[data for this record, with attributes, nested tags, etc.]
</record>
<record>
...
</record>
...
</data>
I have to process the file, convert each record into an object of
a specific class that holds all the info for that record, and call
some kind of business logic for that record (one record at a time).
I guess I can use Xerces for this, but should I use SAX(2)? DOM?
Anything newer? Something in commons or Avalon that abstracts this
even more?
2. I need to process data files with (potentially) multiple formats.
The only format I know for sure will exist is fixed-length fields:
20021225Christmas.......Buy.present.for.Mom...
20021111Birthday........Go.out.and.party......
etc.
where the '.' characters are really spaces, changed to show that
each field is fixed length. The idea would be to read each record,
create an object of a given class that encapsulates it, and call
business logic for it (again, one record at a time). Are there any
Java libraries to handle this kind of task?
3. The eternal object-relational mapping. I have been reading on OJB,
and I like what I know so far. The question here is: at what level
should I use it? The basic Persistence Broker API? The ODMG API?
The JDO API, even thought it is not completely stable yet? Or should
I use a totally different library? For example, I have used Torque
before (from the Turbine project), but I view that as a more
Turbine-related library, and this will not be a Turbine application.
Thanks very much for any insight, and sorry again for being off-topic.
