Axis2 and String[] array issue

[Stefan Geelen]

All,

I have a strange problem with following:

A created a POJO class with following method:

    public byte[] certify(String fieldnames[], String fieldvalues[], String documentURI)  throws Exception { ... } 

I generated the WSDL automatically with java2wsdl

For info: The client is also Axis2

Everything works fine if I pass values for the 3 variables from the client to the server, the webservice body is like following:

<soapenv:Body>
    <ns1:prepare xmlns:ns1="http://services.test.com">
      <ns1:fieldnames>documentURI</ns1:fieldnames>
      <ns1:fieldnames>wNummer</ns1:fieldnames>
      <ns1:fieldvalues>sign/loc/Contract_Onderhoud_voor_website_as_form.pdf</ns1:fieldvalues>
      <ns1:fieldvalues>30</ns1:fieldvalues>
      <ns1:documentURI>sign/loc/Contract_Onderhoud_voor_website_as_form.pdf</ns1:documentURI>
</soapenv:Body>

But when only the documentID is passed, the body is:

  <soapenv:Body>
    <ns1:certify xmlns:ns1="http://services.test.com">
      <ns1:documentURI>certify/brochures/Broch_BelastVermindEnergie2008.pdf</ns1:documentURI>
    </ns1:certify>
  </soapenv:Body>

and I get following error

ERROR: DocumentURI has not been defined: null

(This is an error the program throws when no DocumentID is defined).

When I do some debugging it seems that:
- the fieldnames array has 1 value, the value of the documentURI !?
- the fieldvalues array is empty
- the documentURI is null.

Isit not possible to pass empty arrays to a webservice ?

Is this a bug or am I doing something wrong ?

Let me know if you need more info.

Already thanks for reading this message.

Regards,

Stefan
