|
|What can I expect JAWS to store somewhere in order to be able to do this?
This sentence doesn't make sense...
|Where ? Storage requirements ? Optimized, compressed, ... ? How does this
|"table loader" work?
We make name assumptions about the table, or you specify it with jaws.xml,
please look at the documentation and slow down...
|
|By the way, there does not seem to be a package org.jboss.jaws or something
|like it.
|I can't find any source code that uses the name JAWS?
You haven't looked really hard have you?

|This means that if you do not provide any additional configuration
|metadata the fields will be mapped by name, i.e. CMP field "foo" goes
|into database field "foo". So if you change the CMP field "foo" to be
|called "bar" instead then JAWS will try to write to the "bar" column in
|the database. Now, if you provide a JAWS mapping then you can say that
|the CMP field "bar" should point to "foo" table column. That's all...
|pretty natural I think..
