Hi, I managed to fix my problem.




I am still using ADB, but I added databindingname=“xmlbeans”
as a parameter to axis2-wsdl2java
The new generated code handles empty tags now :)

MG>wanted to make sure your parser parsed RequestType, ResponseType Elements before attempted extension

MG>the good news is that each xmlbean is constructed as a discrete atomic unit before the next bean is constructed
MG>if your ADB RequestType and ResponseType XML elements are discrete atomic units (and not jumbled together)

MG>if you file a bug report I will make sure this problem is addressed
MG>Takk,

Thank you for the suggestion, but still axis won’t handle the XML.

I tried to modify the xsd to this:





<xsd:complexType name="HjemmelResponseType">
  <xsd:annotation>
    <xsd:documentation>Type som inneholder informasjon om en skjermingshjemmel ved response</xsd:documentation>
  </xsd:annotation>
  <xsd:complexContent>
    <xsd:extension base="SkjermingskodeResponseType">
      <xsd:sequence>
        <xsd:element name="Navn" type="cct:navn">
          <xsd:annotation>
            <xsd:documentation>Angir navnet på hjemmelen.</xsd:documentation>
          </xsd:annotation>
        </xsd:element>
        <xsd:element name="Beskrivelse" type="cct:tekst">
          <xsd:annotation>
            <xsd:documentation>Beskrivelse av hjemmel.</xsd:documentation>
          </xsd:annotation>
        </xsd:element>
      </xsd:sequence>
    </xsd:extension>
  </xsd:complexContent>
</xsd:complexType>



but still I get this error message:
org.apache.axis2.databinding.ADBException: Unexpected subelement {urn:no:vegvesen:saksarkiv:felles:typer:1}Hjemmel
When part of the response is on the form


               <Skjerming>
                  <Kode>
                     <Navn>U</Navn>
                     <Beskrivelse>Ugradert</Beskrivelse>
                     <Hjemmel/>
                  </Kode>
               </Skjerming>






Any ideas? Will it help to try to use something else to generate the clientcode  instead of ADB? JiBX?

Hi



I am having a problem with a generated client from a WSDL.
I am using Apache Axis2/Java 1.6.2



We are communicating with a SOAP Service which is returning the following XML structure:

               <Skjerming>
                  <Kode>
                     <Navn>U</Navn>
                     <Beskrivelse>Ugradert</Beskrivelse>
                     <Hjemmel/>
                  </Kode>
               </Skjerming>


MG>take a look at this ResponseType



   <xs:complexType name="ResponseType">

        <xs:sequence>

            <xs:element name="integer1" type="xs:unsignedInt"/>

            <xs:element name="integer2" type="xs:unsignedInt"/>

        </xs:sequence>

    </xs:complexType>

 <!-- the endtag for xs:complexType is here -->

<!-- we may now reference the tag ResponseType in further declarations -->



    <xs:complexType name="UpdateResponseType">

        <xs:complexContent>

<!-- this declaration says for my current UpdateResponseType tag i will extend from predefined ResponseType -->

<!-- the parser has already parsed ResponseType so any tags downstream will be able to extend from it as seen here -->

            <xs:extension base="def:ResponseType">

                <xs:choice>

                    <xs:element name="updateResponseChoice" type="xs:unsignedInt"/>

                    <xs:element name="updateResponseChoice2" type="xs:unsignedInt"/>

                </xs:choice>

            </xs:extension>

        </xs:complexContent>

    </xs:complexType>

MG>



MG>your definition of the 2 responseTypes are jumbled together so the parser is unable to make the distinction between

MG>HjemmelResponseType and  
SkjermingskodeResponseType




The tag named Hjemmel is causing AXIS2 problems. I get a ADBException: Unexpected subelement



The XSD describes the tag like this:




<xsd:complexType name="SkjermingskodeResponseType">
  <xsd:annotation>
    <xsd:documentation>Type som inneholder informasjon om skjermingskode ved response</xsd:documentation>
  </xsd:annotation>
  <xsd:sequence>
    <xsd:element name="Navn" type="cct:navn">
      <xsd:annotation>
        <xsd:documentation>Angir navnet på skjermingskoden.</xsd:documentation>
      </xsd:annotation>
    </xsd:element>
    <xsd:element name="Beskrivelse" type="cct:tekst">
      <xsd:annotation>
        <xsd:documentation>Beskrivelse av avskjermingskoden.</xsd:documentation>
      </xsd:annotation>
    </xsd:element>
    <xsd:element name="Hjemmel" type="HjemmelResponseType">
      <xsd:annotation>
        <xsd:documentation>Angir hjemmel som skal benyttes.</xsd:documentation>
      </xsd:annotation>
    </xsd:element>
  </xsd:sequence>
</xsd:complexType>



<xsd:complexType name="HjemmelResponseType">
  <xsd:annotation>
    <xsd:documentation>Type som inneholder informasjon om en skjermingshjemmel ved response</xsd:documentation>
  </xsd:annotation>
  <xsd:sequence>
    <xsd:element name="Navn" type="cct:navn">
      <xsd:annotation>
        <xsd:documentation>Angir navnet på hjemmelen.</xsd:documentation>
      </xsd:annotation>
    </xsd:element>
    <xsd:element name="Beskrivelse" type="cct:tekst">
      <xsd:annotation>
        <xsd:documentation>Beskrivelse av hjemmel.</xsd:documentation>
      </xsd:annotation>
    </xsd:element>
  </xsd:sequence>
</xsd:complexType>



If i mock the SOAP Service and replaces the <Hjemmel/> tag with the following XML everything works ok:




               <Skjerming>
                  <Kode>
                     <Navn>U</Navn>
                     <Beskrivelse>Ugradert</Beskrivelse>



MG>Here your new tag Hjemmel is being declared with no extensions or relationships to other tags


                     <Hjemmel>
                      <Navn>A</Navn>
                      <Beskrivelse>AAA</Beskrivelse>
                     </Hjemmel>

MG>end tag Hjemmel




                  </Kode>
               </Skjerming>









Is there a way to be able to handle empty elements on the form <tag/> as a client using axis2?
Both for subtrees and for leaf-elements? If I put in a <tag/> for a leaf I get a Nullpointerexception because AXIS2 fails with toString on this element.
