Subject [jira] Reopened: (AXIS2-3331) wrong codegen for anytype
Date Fri, 23 Nov 2007 12:52:43 GMT

     [ https://issues.apache.org/jira/browse/AXIS2-3331?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Yuval reopened AXIS2-3331:
--------------------------


The joy was premature.

On the following return:

<RetrievePropertiesResponse xmlns="urn:vim2">
  <returnval>
    <obj type="Task">task-173</obj>
    <propSet>
      <name>info.progress</name>
      <val xsi:type="xsd:int">20</val>
    </propSet>
    <propSet>
      <name>info.state</name>
      <val xsi:type="TaskInfoState">running</val>
    </propSet>
  </returnval>
</RetrievePropertiesResponse>

propSet is an array of type DynamicProperty, which is defined as:
         <complexType name="DynamicProperty">
            <sequence>
               <element name="name" type="xsd:string" />
               <element name="val" type="xsd:anyType" />
            </sequence>
         </complexType>

The generated code for reading "val" in DynamicProperty contains:
                    object.setVal(org.apache.axis2.databinding.utils.ConverterUtil.getAnyTypeObject(reader,
    com.vmware.vim2.ExtensionMapper.class));
reader.next();

The problem is caused by the convention that parsing an object leaves the XmlStreamReader
iterator on the closing tag. getAnyTypeObject when "val" is "xsd:int" leaves the reader on
CHARACTERS and not on the "</val>" closing tag. This is in conflict with what would
happen for a complex type.

The next code that is executed is:
   while (!reader.isStartElement() && !reader.isEndElement())
      reader.next();
Which excpects to reach the closing tag "</propSet>", but it actually arrives "</val>".
It would return from parsing "propSet" while on "</val>" and next code will fail.

I have fixed it on my code by adding:
                    while (!xmlStreamReader.isStartElement() && !xmlStreamReader.isEndElement())
                        xmlStreamReader.next();
In ConverterUtils.getAnyTypeObject() the end of the true block of the (attributeNameSpace.equals(Constants.XSD_NAMESPACE))
check. I don't know if it is correct.

> Several problems arised with "anyType" code generation. Axis2 1.3 generated it as OMElement,
while the nightly snapshot of Nov 06, 2007 generated it as java.lang.Object.
> Object is wrong because the code will not even compile (it has no .serialize() method).
> OMElement is wrong because it ignores text nodes (string type), thus the "builder2.getOMElement().getFirstElement()"
generated call returns null.
> IMHO it should be generated as OMNode.

> For reference, the full wsdl can be downloaded after free registration from http://www.vmware.com/download/sdk/index.html
(VMware Infrastructure SDK Packages version 2.0.1). I'm using ant, but it should be identical
to the following call:
> java org.apache.axis2.wsdl.WSDL2Java -g -ss -ns2p urn:vim2=com.vmware.vim2,urn:vim2Service=com.vmware.vim2service
-u -uri vimService.wsdl
