[jira] Resolved: (AXIS2-1129) Doubled wrapper elements around
XMLBeans-generated XML
[ http://issues.apache.org/jira/browse/AXIS2-1129?page=all ]
Davanum Srinivas resolved AXIS2-1129.
-------------------------------------
Resolution: Fixed
With latest SVN, please qualify your schema type explicitly ("<xs:element name="full" type="tns:Full"/>") as follows:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:tns="http://www.dummy-temp-address" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:c="http://www.c-corp.com/schemas/c/schema_annotation" targetNamespace="http://www.dummy-temp-address" elementFormDefault="unqualified" attributeFormDefault="unqualified" version="DRAFT">
<xs:element name="full" type="tns:Full"/>
<xs:complexType name="Full">
<xs:sequence>
<xs:element name="message-header" type="tns:MessageHeader"/>
<xs:element name="event-reference" type="tns:EventReference"/>
<xs:any/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="MessageHeader">
<xs:sequence>
<xs:any/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="EventReference">
<xs:sequence>
<xs:element name="event-id" type="xs:string"/>
<xs:element name="update" type="xs:unsignedInt"/>
<xs:element name="response-plan-id" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
Then change the getSituation as follows:
private static FullDocument getSituation()
throws XmlException {
return FullDocument.Factory.parse(
"<full xmlns=\"http://www.dummy-temp-address\">\n" +
// SNIPPED.
"</full>");
}
Then in your method use as follows:
final FullDocument full = FullDocument.Factory.newInstance();
full.setFull(getSituation().getFull());
service.acceptFEvent(full, null, null);
This works for me and generates the following soap message:
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header/>
<soapenv:Body>
<full xmlns="http://www.dummy-temp-address">
<message-header>
<sender>
<organization-id>QSenderOrganizationID</organization-id>
<center-id>QSenderCenterID</center-id>
</sender>
<message-type-version>1</message-type-version>
<message-number>435</message-number>
<message-time-stamp>
<date>20040625</date>
<time>201225</time>
<utc-offset>-0400</utc-offset>
</message-time-stamp>
<message-expiry-time>
<date>20040625</date>
<time>221222</time>
<utc-offset>-0400</utc-offset>
</message-expiry-time>
</message-header>
<event-reference>
<event-id>1234</event-id>
<update>1</update>
</event-reference>
<event-indicators>
<event-indicator>
<priority>4</priority>
</event-indicator>
</event-indicators>
<headline>
<headline>
<incident>accident</incident>
</headline>
</headline>
<details> </details>
</full>
</soapenv:Body>
</soapenv:Envelope>
*PLEASE* note that this is all quirkiness in xmlbeans. you get the correct serialization when you do a toString() is a red herring. If you wrap it in a FullDocument and then call toString() you will see the same problem that we are having.
thanks,

> Project: Apache Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: core, om, wsdl, client-api, databinding
> Affects Versions: 1.0
> Reporter: Derek Foster
> Priority: Blocker
>
> I recently noticed a big problem in how Axis2 generates XML for XMLBeans objects. It appears to be creating the wrapper element around
> an XMLBean twice, thus generating erroneous XML for a SOAP message. This appears to be a big problem that would affect a lot of web services, and is making it impossible for my company to use Axis2 to talk to our server.

> Note that there is a doubled 'full' element in the output (one inside the other). There should be only one level of 'full', but there are two,
> one inside the other. This is very wrong, and is unsurprisingly rejected by my server.
> Calling toString() on the results of getSituation() returns the string that was passed into the Factory.parse() method as I would expect.
> Calling toString() on the FullDocument instance results in two levels of 'full', not one as it should.
> It occurred to me that maybe I should not be including a declaration for 'full' in the string passed to Factory.parse() (note that there is no documentation as to what should be passed into Factory.parse(),making it difficult to interpret), so I tried omitting the outer 'full' tag and its close tag, and just included the elements that it contains. However, when doing this, I got errors from the parse method complaining
> that there was more than one element present in the string being parsed. So although it seems to be possible to generate correct XML via this method as long as there is only a single child element of the 'full' element, this is not an acceptable solution in my case.
> I tried changing the declaration of the 'full' element so that it had minOccurs=0 maxOccurs="unbounded". This caused WSDL2Java to declare the type of it as an array rather than a single instance. However, this merely meant that each element in the array was surrounded by two 'full' tags, rather than one.
> This seems to me to be a fairly blatant error which would affect almost all use of XMLBeans binding. I would like to have this considered
> a blocker for Axis 1.1.
