Re: help: Nesting arrays & structs

[David payam]

hi:

    I also want to know the answer that how I can serialize and deserialize the

arrays of nested beans?

   So would you please send some code to me? or post them here?

 

  Thanks

I too converted my collections to arrays and found that it worked well.
I would also be curious to know why the standard (de)serializers
wouldn't work. I have been using beans and arrays of nested beans
without any trouble, and without needing the custom stuff.

If you want to satisfy your curiosity, you could always submit your
sources with their deployment descriptors here. I am sure someone would
know the answer.

It is possible that you are getting the ClassCastException with your
toArray method, and it is unrelated to Axis. I would test this by
replacing the body of the get method with a statement that returned a
dummy array, with one element.

Take care,
