YES! Just got it going. I had to call the service using the WSDL2Java generated classes. Previously I had been using hand coded classes, but apparently for beans within beans more elaborate mappings are required.
Thanks to you and Marc for keeping me going with new ideas and finding the mapping 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. -----Original Message----- From: Navneet Joneja [mailto:[EMAIL PROTECTED]] Sent: Monday, February 10, 2003 9:36 PM To: 'David Gilbert '; '[EMAIL PROTECTED] ' Subject: RE: deserializing a bean wrapped array of beans 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.

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'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.
