[jira] Reopened: (AXIS2-3797) "Unknown type can not serialize" Exception

Andreas Veithen reopened AXIS2-3797:
------------------------------------

      Assignee: Andreas Veithen  (was: Amila Chinthaka Suriarachchi)

>From the XML schema specification:

"2.5.4 anyType

The anyType represents an abstraction called the ur-type which is the base type from which all simple and complex types are derived. An anyType type does not constrain its content in any way. It is possible to use anyType like other types, for example:

Example
<xsd:element name="anything" type="xsd:anyType"/>
The content of the element declared in this way is unconstrained, so the element value may be 423.46, but it may be any other sequence of characters as well, or indeed a mixture of characters and elements."

Since on the other hand xsi:type is not mandatory, this issue is relevant, so I'm reopening it.

To summarize: While the support for Java types is a real improvement over 1.3, not supporting OMElements and considering xsi:type as mandatory is a clear regression with respect to 1.3.

Detelin, can you describe how exactly anyType was handled in 1.3?

> I have a simple POJO service with the following method:
> package org.tempuri.test;
> import org.tempuri.test.data.arrays.ArrayOfanyType;
>  
> public class TypeTest {
>     public ArrayOfanyType retArrayAnyType1D(ArrayOfanyType inArrayAnyType1D) {
>         return inArrayAnyType1D;
>     }
> }
> The ArrayOfanyType is declared like this:
> public class ArrayOfanyType {
>     private Object[] anyType;
>     public Object[] getAnyType() {
>         if (anyType == null) {
>             anyType = new Object[0];
>         }
>         return this.anyType;
>     }
>     public void setAnyType(Object[] anyType) {
>     	this.anyType = anyType;
>     }
> }
> I deploy this POJO on an Axis2 1.4 runtime running on Tomcat.
> Then I generate a client stub using the following command:
> wsdl2java -ap -o ./generated -s -u -uw -uri http://localhost:8080/axis2-1.4/services/TypeTest?wsdl
> I use the stub to invoke the service passing an OMElement in the Object array:
> OMFactory factory = OMAbstractFactory.getOMFactory();
> OMNamespace ns = factory.createOMNamespace("http://www.serverside.com/articles/introducingAxiom", "article");
> OMElement articleElement = factory.createOMElement("Article", ns);
> ArrayOfanyType input = new ArrayOfanyType();
> input.setAnyType(new OMElement[]{articleElement});
> stub.retArrayAnyType1D(input);
> While serializing the ArrayOfanyType ADBBean I get an "Unknown type can not serialize" exception:
> Caused by: javax.xml.stream.XMLStreamException: Unknow type can not serialize
> 	at org.apache.axis2.databinding.utils.ConverterUtil.serializeAnyType(ConverterUtil.java:1449)
> 	at org.tempuri.test.data.arrays.xsd.ArrayOfanyType.serialize(ArrayOfanyType.java:241)
> 	at org.tempuri.test.data.arrays.xsd.ArrayOfanyType.serialize(ArrayOfanyType.java:160)
> 	at org.tempuri.test.RetArrayAnyType1D.serialize(RetArrayAnyType1D.java:203)
> 	at org.tempuri.test.RetArrayAnyType1D.serialize(RetArrayAnyType1D.java:123)
> 	at org.tempuri.test.RetArrayAnyType1D$1.serialize(RetArrayAnyType1D.java:111)
> ...
> I did not have this problem on Axis2 1.3 so I guess something have been changed in ConverterUtil.
