As the Java classes generated by the XML code generator (aka source generator) are JavaBeans compliant, the answer is ... well, no. I don't see a reason as to why a JavaBeans wrapper should be generated when the classes in question are JavaBeans themselves.

If so, this would be very useful in writing "marshalling servlets". Basically, we can use this to marshal XML from request parameters of a jsp. This would be very useful for my project except that I am somewhat lazy and reluctant to write the bean wrappers myself (which will all have to change for any change in XSD). Catch 22 is that I cannot use castor classes directly as beans since castor itself is using the default constructors. Hope I am making sense...Thanks. ________________________________________ From: Uday Kari Sent: Thursday, August 31, 2006 11:52 AM To: 'Arnaud Blandin'; [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: Java Bean Wrapper for Castor Classes Arnaud: Thanks for your response. Look forward to hearing from Werner and/or Keith. At this stage, all I have is raw source...anything that explains the inner working a little better would be useful. As I said, I would be honored to contribute code, but need some help getting started and perhaps be more effective. I would much rather prefer this type of team work (or endorsement or blessing!), rather than attempting to do an extension that is completely homegrown (especially in production).

Maybe you could expand the binding file to add the proper functionality. Unfortunately I cannot help you more at this stage as I am not active anymore on the project. I am sure Werner or Keith can guide you.

I am unable to use Castor generated classes directly as java beans since the required default constructor is used for all sorts of the namespace related housekeeping. Therefore, I am unable to set member variable directly as bean properties from, say, HTTPrequest. Also, since Castor classes generate properties such as BigDecimal, I would like to handle converting string parameters from request before setting properties. Therefore, the best strategy was to create java bean wrappers to: A. Appropriately convert request parameters to Castor generated data types. B. Pass through these parameters from the java bean wrapper to the corresponding Castor "twin" class. C. When marshalling and unmarshalling, the presentation layer thinks it is dealing with the java bean, but it is the Castor implementation layer underneath that handles everything. I have tested the idea successfully, by hand-coding the required bean wrappers. However, when dealing with complex XSD as follows: http://www.pdc.org/pride/xmlschema/ptwc.xsd ... I really wish I could generate these bean wrappers "automagically" just like Castor generates classes from XSD, simply because since there are so many (140 classes) of them !! If you could give me some tips on how exactly you conduct the transformation of XSD into Castor classes (through architecture documents, dataflow diagrams), I would be glad to contribute some code to your project that generates these java bean wrappers for Castor classes. I am just beginning to decipher the code, but don't have much documentation or forums to work with. I am sure there are other developers who could use this. Alternatively, you could give me some tips on why I should not be doing this (i.e. can I somehow create one "master class" to marshal/unmarshall any of its 140 child objects?).
