I don't see a definition for your default namespace. Is it set to the
xsd namespace? If not, then this:
<xs:element name="Request" type="base64Binary" use="required"/>
should be this:
<xs:element name="Request" type="xs:base64Binary" use="required"/>
Likewise for the "Result" element.

Hello,
I am trying to transfer binary data. I wrote a wsdl file with the following
part:
<wsdl:types>
<xs:schema
targetNamespace="http://businessobjects.com/services/sample/byte1";>
<xs:element name="SetIdRequest">
<xs:complexType>
<xs:sequence>
<xs:element name="ID" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="Request" type="base64Binary" use="required"/>
<xs:element name="Response">
<xs:complexType>
<xs:sequence>
<xs:element name="ID" type="xs:string"/>
<xs:element name="Result" type="base64Binary"
use="required"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
</wsdl:types>
The Request and Result should be in binary data. When auto generating the
code, then these elements are generated as OMElement. I created the
OMElement as follows:
…
OMFactory fac = OMAbstractFactory.getOMFactory();
OMElement element = fac.createOMElement("data", omNS) ;
DataHandler dataHandler = new DataHandler(data);
OMText textData = fac.createOMText(dataHandler,false);
textData.setOptimize(true);
element.addChild(textData);
request.setRequest(element);
…
As far as I understand the binary data will now be contrained in the OMText
element and the request look like this:
<ns2:Request
xmlns:ns2="http://businessobjects.com/services/sample/byte1";>
<data
xmlns="http://businessobjects.com/services/sample/client/byte1";>ICAgT...</data>
</ns2:Request>
I believe so far I have not done anything wrong. The problem occurs when
trying to parse the request. I get an error that when trying to get the text
element from the request stating: org.apache.axiom.om.OMException:
java.util.NoSuchElementException
However, when trying to debug the same code, I end up in an endless loop.
The auto generated code for parsing is as follows:
public static Request
parse(javax.xml.stream.XMLStreamReader reader)
throws java.lang.Exception {
Request object = new Request();
int event;
try {
while (!reader.isStartElement() && !reader.isEndElement())
reader.next();
// Note all attributes that were handled. Used to differ
normal attributes
// from anyAttributes.
java.util.Vector handledAttributes = new java.util.Vector();
while (!reader.isEndElement()) {
if (reader.isStartElement()) {
if (reader.isStartElement()) {
java.lang.String content =
reader.getElementText();
System.err.println(content);
org.apache.axiom.om.OMFactory fac =
org.apache.axiom.om.OMAbstractFactory.getOMFactory();
org.apache.axiom.om.OMNamespace omNs =
fac.createOMNamespace("http://businessobjects.com/services/sample/byte1";,
"");
org.apache.axiom.om.OMElement _valueRequest =
fac.createOMElement("Request",
omNs);
_valueRequest.addChild(fac.createOMText(
_valueRequest,
content));
object.setRequest(_valueRequest);
} // End of if for expected property start element
else {
// A start element we are not expecting
indicates an invalid parameter was passed
throw new java.lang.RuntimeException(
"Unexpected subelement " +
reader.getLocalName());
}
} else {
reader.next();
}
} // end of while loop
} catch (javax.xml.stream.XMLStreamException e)
{
throw new java.lang.Exception(e);
}
return object;
}
Is there something wrong in my wsdl file, in the auto generated code, or in
the way I am using the code?
Thanks for the advice,
Christina
