David,
  Is this array coming from your client-side code that's callling the
service? And can you successfully deploy the server-side code, get the
service to appear in axis's list of service, and successfully view the wsdl?

Marc,

I have done as instructed below, but still have the same problem with a new
namespace.  Conceptually I don't understand how Axis would know how to
deserialize the Products within the Catalog without a namespace being
provided for the Product object to assist in mapping to a deserializer.
When I make the call to get the Catalog I specify the namespace that will be
returned for the Catalog and Axis is able to map the object name and the
namespace to the beanMapping or typeMapping.  How would Axis know the
namespace to use for looking up the deserialization mapping for Products if
I don't specify it as part of the call?  Both Catalog and Product currently
use the same namespace, but when returning the Catalog I am still getting -

org.xml.sax.SAXException: No deserializer defined for array type
{http://util.regisproject}Product.

Here are the new deploy.wsdd file contents:

Subject: RE: deserializing a bean wrapped array of beans


David,
  I've been able to successfully return an array of objects, and each of
those objects has an array of other objects. Here's my approach, which Gene
Chuang helped me get started with back in January:

1) In some development directory, code the service. I keep all service
classes and beans underneath the same root package (i.e. package mypkg;
package mypkg.beans; and the like)

2) compile, then copy the root package to the
$TOMCATHOME/webapps/axis/WEB-INF/classes directory

    thus, you might end up with
$TOMCATHOME/webapps/axis/WEB-INF/classes/ArticleSearch3

3) from that directory, run java2wsdl. for example:
java org.apache.axis.wsdl.Java2WSDL -o
rticleSearcher3.wsdl  -l"http://localhost:8080/axis/services/ArticleSearcher
3" -n urn:ArticleSearch3 -p"ArticleSearch3" urn:ArticleSearch3
ArticleSearch3.ArticleSearcher3
   See the docs for an explanation of the switches and parameters

4) copy the generated wsdl into a temp folder

5) cd to your temp folder, and run wsdl2java with the server-side switch to
get the deploy and undeploy.wsdd files.
  Here's what I put in the command line: java
org.apache.axis.wsdl.WSDL2Java --server-side ArticleSearcher3.wsdl

6) Copy the deploy and undeploy.wsdd files to your service's directory (i.e.
$TOMCATHOME/webapps/axis/WEB-INF/classes/ArticleSearch3)

7) Now comes the part that was hanging me up before: editing your
deploy.wsdd file. Underneath the service element is a parameter element with
the "className" attribute. This will probably be something like this:

   <parameter name="className"
value="ArticleSearch3.ArticleSearcher3SoapBindingImpl"/>

Delete the "SoapBindingImpl" part, such that you end up with

   <parameter name="className" value="ArticleSearch3.ArticleSearcher3"/>

 I also delete the wsdlServicePort, wsdlServiceElement, and wsdlPortType
parameters, per Gene's advice, although I haven't studied the consequences
of this yet.

8) If you've followed these steps so far, the deploy.wsdd should contain the
appropriate typemappings, which I've pasted to the end of this email. You
should see an array de/serializer mapping for each array, and a bean
de/serializer for each bean class. This is what you're missing from the
deploy.wsdd file.

9) make sure you're in your service's directory
(..../classes/ArticleSearch3), and run the AdminClient, like so: java
org.apache.axis.client.AdminClient deploy.wsdd

10) This should update your server-config.wsdd file in the
webapps/axis/WEB-INF directory with the information for your new service.

11) go to axis's localhost homepage and view your list of services.
Hopefully, it'll be there.

To quickly see whether your service works (assuming you're able to view the
wsdl), use the .NET Web Services Studio, which is available free from
Microsoft. You just point it to your wsdl file, and it'll do the rest. It
should prompt you with parameters to enter, and then it'll call your service
and show you the results.

in this deploy.wsdd, you'll notice ArticleSearch3 and ArticleSearcher3. This
is just bad code on my part.  ArticleSearch3 is the package name, and
ArticleSearcher3 is my service's primary class.

Good luck, David. Let us know how you make out.

Marc

Thanks for the idea, but if add urn: to the beanMapping and use the urn:
namespace on the client it still throws the same error.  Has anyone else had
any luck or experience with returning a bean that has an array of beans
inside it?  Does axis need to be told that one class holds members of
another class, or should axis just deserialize bean objects as it finds them
no matter what?

Thanks for any ideas/help/thoughts, and especially answers.

Hi David,

I'm not sure your namespaces are well-formed.
Try to add "urn:" at the beginning of your namespaces
("urn:ProductDbHelper" instead of "ProductDbHelper", etc).

HTH,
