Here's your problem:
field.setXmlType(new javax.xml.namespace.QName("http://util.regisproject";,
"Product"));
typeDesc.addFieldDesc(field);
If you look at the WSDL definition of the field, it should have been
ArrayOf_tns2_Product instead of Product.
If you change that, your service should work.
Looks like the same bug to me :)

Subject: RE: deserializing a bean wrapped array of beans
Maybe we don't have the same problem. I am assuming you used the WSDL2Java
command to generate your beans. I have done the same on my code and
reviewed the new beans. My parent bean (Catalog) seems to have the inner
bean (Product) as an array for the getter and setter methods:
public class Catalog implements java.io.Serializable {
private regisproject.util.Product[] products;
public Catalog() {
}
public regisproject.util.Product[] getProducts() {
return products;
}
public void setProducts(regisproject.util.Product[] products) {
this.products = products;
}
...
And the type metadata sections look like this:
// Type metadata
private static org.apache.axis.description.TypeDesc typeDesc =
new org.apache.axis.description.TypeDesc(Catalog.class);
static {
org.apache.axis.description.FieldDesc field = new
org.apache.axis.description.ElementDesc();
field.setFieldName("products");
field.setXmlName(new javax.xml.namespace.QName("", "products"));
field.setXmlType(new
javax.xml.namespace.QName("http://util.regisproject";, "Product"));
typeDesc.addFieldDesc(field);
};
/**
* Return type metadata object
*/
public static org.apache.axis.description.TypeDesc getTypeDesc() {
return typeDesc;
}
Is field.setXmlType where you changed Cow to ArrayOfCow? I changed mine to
look like:
field.setXmlType(new javax.xml.namespace.QName("http://util.regisproject";,
"ArrayOfProduct"));
and
field.setXmlType(new javax.xml.namespace.QName("http://util.regisproject";,
"Product[]"));
and it still doesn't work. Am I in the right place?
Did your original error say anything about "No deserializer for array
type..."? I am thinking we have different problems, but I would like to
understand your problem and fix to see if there is any relationship that
could rub off to help fix my problem.

David,
I edited the metadata in the generated bean (the bean that contains the
array of other beans). In the XML type metadata, it had the type mentioned
as Cow (where Cow was the nested bean), rather than ArrayOfCow, so I changed
it to ArrayOfCow, and all was well.
Sorry I can't send the actual code as it's proprietary, but I could send you
the modified axis.jar that I built and you could try generating the client
stubs with it and see if it works.

It certainly could - I am using the 1.1 beta also. Can you please
explain
how you got your service to work in more detail? Specifically, which
meta

Thanks.

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?

Subject: RE: deserializing a bean wrapped array of beans
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.

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.

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?

Hi David,
I'm not sure your namespaces are well-formed.
Try to add "urn:" at the beginning of your namespaces
