java.io.IOException: Emitter failure. There is an undefined binding (HelloServerBinding) in the WSDL document.

Hi,

I got the error  :

java.io.IOException: Emitter failure.  There is an undefined binding (HelloServerBinding) in the WSDL document.
Hint: make sure <port binding=".."> is fully qualified.

I checked my WSDL file and everything seems ok. I'm not able to figure out why I am getting this error.

I have included the WSDL file below.

Any help is appreciated.
Thanks in advance,
Nitesh

RE: java.io.IOException: Emitter failure. There is an undefined binding (HelloServerBinding) in the WSDL document.

Posted by Anne Thomas Manes <an...@manes.net>.

Nitesh,

I agree that your QNames look okay, but there are quite a few problems with
your WSDL. You've got a serious mix and match of RPC/encoded and
document/literal definitions.

I think your specific error is caused by the way you've defined your
<soap:body> elements:

<soap:body
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
	namesapce="http://craft.epfl.ch/wsdl/HelloServer.wsdl"
	use="literal"/>

1) you have "namespace" spelled wrong (so perhaps wsdl2java ignored the
binding definition -- hence no binding was defined)
2) you should not use the "encodingStyle" and the "namespace" attributes on
document/literal bindings.

Your <soap:body> elements should be defined like this:

<soap:body use="literal"/>

You also have typos in some of your message names:

	<message name="sayHellToRequest">
		<part name="name" type="xsd:string"/>
	</message>

Some basic guidelines for doc/literal bindings:
- Don't use the soapenc:array type. Define your own array using the
minOccurs and maxOccurs attributes.
- You have only one message part per message. That message part must
reference an element definition rather than a type definition.
- To use the Wrapped style, the referenced element definition must have the
same name as the portType operation name. The element must be defined as a
<sequence>. The operation parameters are defined as elements within the
sequence.

For example, your addRequest message should be defined like this:

	<message name="addRequest">
		<part name="parameters" element="tns:add"/>
	</message>

And the add element should be defined like this:

	<element name="add">
        <complexType>
          <sequence>
		<element name="num1" type="xsd:int"/>
		<element name="num2" type="xsd:int"/>
          </sequence>
        </complexType>
	</element>

I suggest you get a WSDL editor to help you define your WSDL documents. The
Cape Clear SOA Editor is free. See
