HTTP GET REST requests fail for valid ADB generated data bindings.
------------------------------------------------------------------
Key: AXIS2-1644
URL: http://issues.apache.org/jira/browse/AXIS2-1644
Project: Apache Axis 2.0 (Axis2)
Issue Type: Bug
Components: kernel
Affects Versions: 1.0
Environment: GNU/Linux 2.6.18-1.2200.fc5smp, SUN Java 1.5.0_09,
Apache Tomcat 5.5.20, Axis2 1.0
Reporter: Damon Lanphear
I've been working on getting REST support working using HTTP GET for a service
specified using the contract-first idiom, and code generated using WSDL2Java.
The data binding is Axis Data Binding (adb).
It appears that there are mismatches between the expectations of the
generated adb code and the output of the URL to SOAPEnvelope transcoder:
SchemaUtil.handleMediaTypeURLEncoded()
1) SchemaUtil.handleMediaTypeURLEncoded() appears to strip off the
namespace information when constructing an OMElement for the SOAP
message body. The ADB data binding assumes that the namespace
information is present when unmarshalling SOAP message input.
2) SchemaUtil.handleMediaTypeURLEncoded() assumes that complex XML data
types are specified as <sequence> as opposed to <all>. Attempts to use
complex types specified with <all> will silently fail.
Replacing the call to createOMElement in SchemaUtil.handleMediaTypeURLEncoded()
to:
soapFactory.createOMElement(name,
soapFactory.createOMNamespace(targetNamespace,
xmlSchemaElement.getQName().getPrefix()),
bodyFirstChild).setText(parameterValuesArray[0]);
Fixes this problem for me.
The WSDL in case is provided here:
