Serializing an array of beans
Hi, I'm going round in circles trying to serialize an array of beans.
First I tried using the Apache Bean Serializer, specifying it in the
deployment descriptor; this worked for one bean, but not for an array.
I then wrapped the array in another class, then tried to write my own
serializer for the wrapper class, and refer to this serializer in the
deployment descriptor.
This produces an error on post whenever I change it to point from anything
but the apache serializers.
I am inspecting the XML returned from the soap servlet, the output is shown
below.
On the server end, is using the deployment descriptor (e.g. xml2java...
attribute) sufficent to successfully invoke my serializer when returning a
reply?
>From the client end I am using perl SOAP::Lite to invoke the function. On
the server end I am using the StatelessSessionBean provider to invoke a
method whose return type is the object array.
Has anyone managed to write and make work an object array serializer on
Apache SOAP 2.2. If so, do you have any code/class/deployment descriptors I
could look at?
Thanks,
Andrew

Andrew,
I can send you one of my serializers, however, I used the Apache-SOAP ones
as a template, so they're not much different.

Hi Chris, this looks promising.
However, I'm having trouble using ANY type of home-grown serializer, and
would like to use one which someone knows works (other than the apache ones
which come with the distribution).
Thanks,

Hi Chris, this looks promising.
However, I'm having trouble using ANY type of home-grown serializer, and
would like to use one which someone knows works (other than the apache ones
which come with the distribution).
Thanks,
Andrew
