I'll tell you truth: there is no such tag. And it's unlikely that one will emerge soon ( before 2.0 ) Current templating language is not very good ( you must have figured it yourself ), and all the iterations are defined in various tag handlers, so we just can not produce generic tag which would check for last iteration. > I'm writing an xdoclet template to auto-generate > JUnit tests for the EJBs > I'm making in my current project, and part of my > template looks like this: > > MyObject = new MyObject( > <XDtEjbPersistent:forAllPersistentFields> > TEST_<XDtMethod:methodNameWithoutPrefix/>, > </XDtEjbPersistent:forAllPersistentFields> > ); > > This iterates through all persistent fields in the > EJB, and for each one > outputs a variable name beginning with "TEST_", and > the whole thing is > surrounded by "MyObject = new MyObject(.....);" > E.g. given the fields > "UserId", "Colour" and "Age" - the desired output > would be: > > MyObject = new MyObject(TEST_UserId, TEST_Colour, > TEST_Age); > > So far so good.

Hmm, there are tags dooing similar stuff for patameter lists for DataObject / Value object - and you will be able to use them, since you have living EJB to work with: <XDtEjbPersistent:persistentfieldList superclasses="true"/> will produce parameter definition list <XDtEjbPersistent:persistentfieldNameValueList/> produce list without type names to be used for invocations. regards, ===== Konstantin Priblouda ( ko5tik ) Freelance Software developer < http://www.pribluda.de > < play java games -> http://www.yook.de > < render charts online -> http://www.pribluda.de/povray/ > __________________________________________________ Do you Yahoo!?
