Hi,
Quick question...(?)
Is it possible to do something like the following? (or am I tackling it
wrong?)
(<XDtEjbPersistent:forAllPersistentFields superclasses="false">
java.lang.String <XDtMethod:propertyName/>
<**ifNotLastPeristentFieldThenPrintThis**>,</**ifNotLastPeristentFieldThenPr
intThis**>
</XDtEjbPersistent:forAllPersistentFields>)
Thanks
Chris

Write a template and decide on the type what to do. You have to do a lot
of if/elses and handle each type differently. You can also write
decoders (like the way Soap converts types from string to java, using a
set of demarshallers).
In my application I'm doing the reverse: I construct an
XmlConfiguration, passing in a Class, load an xml file, look at the
Class and for each attribute I try to do a getMethod("get"+attrname),
then I check the type of the return type and in a big if/else convert
the string to the return type of the method and do a "set"+attrname()
passing in the converted value. I handle it in runtime, and based on the
assumption that there's get/set for attributes of the xml file in the
bean. It's pricier in runtime obviously. You may be interested to handle
it using Castor XML for example. It's also absolutely possible to
implement using a specialized xdoclet template files. Depends on your
taste :o) If I were to implement it now I would write a template (I'm
writing templates each day for various automation cases I face in our
app!!), using the strategy dataobject generation uses. Actually the
tricky part is the type conversion part because there's no generic way
to handle it and you should tackle it case by case for each type.
Cheers,
Ara.
