Re: [castor-user] XML - nested mapping issues in webapp vs. jUnit test class

Andrew,

If you are having problems with naming conventions then it sounds like you may be using a static method on the Unmarshaller. The mapping file supports mixed case (camel case) names for elements and attributes.

The default introspector (by default) uses lower case names with a hyphen '-' to separate words. This can be configured in the castor.properties file to use mixed case as well.

So it sounds to me like default introspection was taking place and you mapping was being ignored.

In such situations, it's usually that a static method was being invoked on the Unmarshaller (or Marshaller). When using the static methods any mapping file set on the Unmarshaller will be ignored since a static method doesn't have access to non static variables.

werner,

thanks for your concern. i'm fairly certain that i had problems with naming
conventions where i was using standard java names instead of '-' for xml
node elements and attributes, and i also think that my build script was not
working correctly - hence the problem lay elsewhere than castor!

thanks again!

Andrew,

can you please post the full stack trace ?

werner,

i keep getting MappingException's thrown when attempting to set the
mapping
file onto the unmarshaller - but again, seems to work fine in a test
class...

Andrew,

what problems are you experiencing ?

i am attempting nested object mapping with castor xml and have problems


when

moving between a junit test class and a webapp i.e. the test class works whereas the webapp mapping does not.

i am certain however, that this is NOT a classpath problem, the


classpaths

are identical in both environments as my first conclusion was that this
might be the issue...
i'm not ruling out the possibility that it is a fluke that it works in

the

standalone test class because my mapping configuration is not quite


correct!

i can't however find many examples of 3-level nested class mapping and


have

read reports of flakiness when performing nested mapping - if anyone else
has had similar problems or has any suggestions then i'd be really


grateful

to hear from you!
