Hi Alex, The component in question is XML code generator.

I'm thinking either Unknown, Core or General. Btw, have a look at the code base. There's a main.vm, afair. This will get loaded somewhere.

No, this is not about 'competitors', as I would not know what e.g. JAXB RI has to offer. There#s one thing you could investigate (and that just crossed my mind: there's a module within Maven (modello?) that uses Castor internally to enrich POJOs with custom code. Have a look at some Jira issues, which contain cross-references to this. I don't have the time to search now, but if you don't find anything I'll have a close look in the evening. > > Alex > > On Sep 9, 2009, at 6:12 AM, Werner Guttmann wrote: > >> Hi Alex, >> >> Alex Thieme wrote: >>> >>> Werner, >>> >>> Thanks for the answers.
