Hi ,
I have a small issue while persisting EMF (XMI) as XML .I have an EMF
model I want that model to be persisted as XML
E.g I have Struts EMF model and it needs to be persisted as
Struts-config.xml
I have a set of Mappings EMF Feature to XML element , but i get errors
while loading the model
Say for e.g my Root Feature StrutsConfigType of EMF is mapped to a XML
element <struts-config> , its saving properly but when i try to load the
same in the editor its searching for the struts-config as feature rather
than my actual StrutsConfigType EClass .
Any pointers and help in this Regard will be highly apperiaciated.Also
some examples on using EXTENDED_META_DATA option and its sub classes
Thanks,
Kamesh

Kamesh,
One of the things you can do is Generate Test Code and that will produce
an XyzExample.java in the *.tests project. With that you should be able
to reproduce any problems in a minimal environment. If you could zip up
your model project and your *.tests project for that model, modified to
reproduce the problem you are seeing, then I can much more easily answer
your question via such a concrete example. You can send it to my e-mail
directly if you don't wish to make it public in the newsgroup as an
attachment. My e-mail is merks at ca dot ibm dot com.
