exactly that was my intention. So: Between <class>...</class> there ist only a string, the Class is not introspected. And I need the class-property only in class derived from Throwable, not for all classes. For my usecase it would work if there is a switch, in the IntrospectionConfiguration for example, where I can put the output of class-property on/off. Then I would turn it on for all and add sumething like <hide property='class'/> to my dot-betwixt files. But it would be nicer and more flexible if everybody could plug in his custom strategy. A defaults strategy available: with-all-class-properites and without-all-class-properties. Another thing is, that I need the cause of the exception, I handled that with the patch. > but it's important that i understand your use case so i make that i > cover it. so, you saw, its realy a simple case, class-properties in all class extending Throwable. > i'm happy to take a look at coding this up but i other pots on the boil > right now so it might take a few days... sure. And thank you a lot for having a look at this. I would code it myself and send a patch, if I could, but I'm not so into the betwixt code. There is a lot of deprecated code, and this not yet finished (?) change of the mapper for simple/complex types. regards and thanks Christoph ----- Original Message ----- From: "robert burrell donkin" <[EMAIL PROTECTED]> Newsgroups: gmane.comp.jakarta.commons.devel Sent: Monday, September 27, 2004 11:51 PM Subject: Re: [betwixt] Howto serialize the classname when writing XML > On 26 Sep 2004, at 18:59, Christoph Gaffga wrote: > > > hi, > > > > I have to output some Exception instances to XML using betwixt, but it > > doesn't seem to be possible to get the class name into the XML result. > > yep. it's on the todo... > > > First of all it should output the name of the class only, and not > > introspect > > the whole Class type.
