Namespace and bean mappings in response??
Hello,
We are currently using Webmethods Glue 5 as our SOAP interface to our
Webservices (which are consumed by multiple .NET applications). We want
toget rid of Glue and switch to Axis.
We however have some problems. The .NET applications expect a certain format
of SOAP response (which is currently created by Glue) and we can't seem to
reproduce this SOAP response with Axis 1.3.
We have a Java Bean which contains the response. This Bean (called
ProductResponse) extends a Java Bean called FrameworkReponse (which contains
responses that are similar for all our webservices, for example error
responses). This FrameworkResponse bean contains 2 arrays of other
JavaBeans, namely Error and Message.
Now, when we get an error response (which is contained by our Error bean,
which in it's turn is contained by our FrameworkResponse bean) Glue returns
the following SOAP message:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:n1="
http://services.company.com/product/package/company.framework.w
ebservice.responsemodel /"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soap:Body>
<n:getProductResponse xmlns:n="http://company.com/product">
<n:Result>
<errors>
<n1:Error>
<optionalDescription>Lookup
error</optionalDescription>
<errorText>Product lookup error</errorText>
<errorID xsi:nil="1"/>
<errorCode>501</errorCode>
</n1:Error>
</errors>
<messages xsi:nil="1"/>
<product xsi:nil="1"/>
</n:Result>
</n:getProductResponse>
</soap:Body>
</soap:Envelope>
The message that Axis generates on the same request looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema "
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<getProductResponse xmlns="http://company.com/product ">
<Result>
<errors>
<errors>
<errorCode>501</errorCode>
<errorID xsi:nil="true"/>
<errorText>Lookup error</foutText>
<optionalDescription>Product lookup
error</optionalDescription>
</errors>
</errors>
<messages xsi:nil="true"/>
<product xsi:nil="true"/>
</Result>
</getProductResponse>
</soapenv:Body>
</soapenv:Envelope>
As you can see, in the Glue response the <errors> tag encapsulates a <Error>
tag (which is the same name as our bean's classname and is in the namespace
"
http://services.company.com/product/package/company.framework.webservice.responsemodel"
. However, in the Axis response the <errors> tag encapsulates another
<errors> tag which is in the same namespace as our <getProductResponse>.
The <service> part of my wsdd looks like this:
<service name="ProductService" style="wrapped">
<parameter name="className" value="comany.web.ProductServiceEndPoint
"/>
<parameter name="allowedMethods" value="getProduct"/>
<beanMapping qname="example:ProductKey" xmlns:example="
http://comapany.com/product" languageSpecificType="java:company.ProductKey"/>
<beanMapping qname="exampleresp:Result" xmlns:exampleresp="
http://company.com/product" languageSpecificType="java:
company.web.response.ProductResponse"/>
<beanMapping qname="respframework:Error" xmlns:respframework="
http://company.com/product/package/company.framework.webservice.responsemodel/"
languageSpecificType="java:company.webservice.responsemodel.Error"/>
<beanMapping qname="respframework:Message" xmlns:respframework="
http://company.com/product/package/company.framework.webservice.responsemodel/"
languageSpecificType="java:
company.com.framework.webservice.responsemodel.Message"/>
<operation name="getProduct" qname="nsname:getProduct" xmlns:nsname="
http://company.com/product"
returnQName="nsname:Result">
<parameter name="key"/>
</operation>
</service>
As you can see, I have defined a bean mapping from my Error bean to an xml
entity with the qualified name: "respframework:Error" where "respframework"
is "
http://company.com/product/package/company.framework.webservice.reponsemodel/".
So why doesn't Axis use this namespace in the response but the namespace of
the getProductResult instead?? And why does Axis not map the Error bean to
an <Error> tag (the name of the bean) but to an <errors> tag???
Another question. I have specified the bean mapping of my ProductResponse
bean to an xml <Result> element. However, when I do this, the I get an xml
<getProductResponse> tag instead of a <Result> tag. I've solved this by
specifying this qname in the <operation>, but why do I have to do this? Why
doesn't Axis use the specified beanmapping in its reponse SOAP message??
With kind regards,
Duncan Doyle

Well, our .NET web-frontends depend on our current WSDL, they won't like
it when I change it. Because Axis seems to discard my response
bean-mappings from the WSDD, I tried to create the Java classes from our
current WSDL with WSDL2Java. It gave me some helper classes which
contain the correct mappings. However, when I try to run my application
with these helper classes, my WebSphere (WAS 5.1) server starts
complaining about classloader problems (this seems to be a known
problem, I found a couple of posts on discussion forums regarding this
issue).
So, as long as I can't define the correct mappings in my WSDD, Axis
seems to be a "no go" for us. I really want to use Axis, so I hope that
someone has a solution to my problems.
With kind regards,

I suggest you start with your WSDL rather than your code.
