Re: anyType and til values/empty strings - exception thrown

Hi!

Its not my code, its the code generated by wsdl2java - so what can I do?

Anyway, the code is wrong and should use getElementText instead of
getText to make sure that it gives the expected result even if the
underlying parser is not coalescing. This would also solve the problem
with empty text (getElementText returns an empty string in that case)
and I think that is what the generated code does. Note that your last
comment implies that anyType handling uses totally different code than
the processing of typed elements. This is really strange!

Hi!

I created a wsdl which contains a attribute/value pair where the
value is definied as xsd:anyType:

<xs:complexType name="ZAttributeValue">
 <xs:sequence>
   <xs:element name="name"                        type="xs:string" />
   <xs:element name="displayName" nillable="true" type="xs:string" />
<xs:element name="value" nillable="true" type="xs:anyType" /> 
   <xs:element name="className"   nillable="true" type="xs:string" />
 </xs:sequence>
 </xs:complexType>
Now I used wsdl2java to create client and server code using adb data binding. 

When value is "" (=empty string), the client throws this exception:
Exception in thread "main" org.apache.axis2.AxisFault: Current state END_ELEMENT is not among the statesCHARACTERS, COMMENT, CDATA, SPACE, ENTITY_REFERENCE, DTD valid for getText()

       at de.debeka.repository.zws

In this case, the soap message looks like this:

<attributes xmlns="http://model.zws2.boq.debeka.gen/xsd";>
 <name>HINWEIS</name>
 <displayName>Hinweis</displayName>
<value xmlns:s45="http://www.w3.org/2001/XMLSchema-instance"; xmlns:s46="http://www.w3.org/2001/XMLSchema"; s45:type="s46:string"> 
 </value>
 <className>java.lang.String</className>
</attributes>

When value is set to null, I get this exception:
Exception in thread "main" org.apache.axis2.AxisFault: org.apache.axis2.databinding.ADBException: Unexpected subelement value 
       at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430)

The soap message is:

<attributes xmlns="http://model.zws2.boq.debeka.gen/xsd";>
 <name>KLASSE</name>
<displayName xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:nil="1" /> <value xmlns:s29="http://www.w3.org/2001/XMLSchema-instance"; xmlns:s30="http://www.w3.org/2001/XMLSchema"; s29:type="s30:string">C_Jobplan</value> 
 <className>java.lang.Integer</className>
</attributes>
I tried Axis2 1.4.1 and the new 1.5 version. The whole problem with nil and empty string values only exists with anyType, not if the element is declared 
as string or something else.

I really need anyType here.

Thank you for your help in advance.
