Calling an Axis Web Service with a SOAP client

Ben Abramson Wed, 01 Jun 2005 09:08:01 -0700

Hello,

I have written an Axis web service, which I have successfully invoked with an Axis client. I’m now trying to write an equivalent client using standard SOAP. The relevant code in the SOAP client looks something like:

cl.setTargetObjectURI("urn:dohello");

cl.setMethodName("sayHello");

cl.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);

Vector params = new Vector();

params.addElement(new Parameter("name", String.class, name, null));

params.addElement(new Parameter("age", Integer.class, a, null));

cl.setParams(params);

When I then try to invoke the call using the command:

response = cl.invoke(ept, "");

Where ‘ept’ is the URL of my service. I’m expecting a string back (nothing complex), but I get an exception that tells me it can’t find a deserializer:

[SOAPException: faultCode=SOAP-ENV:Client; msg=No Deserializer found to deserialize a 'http://schemas.xmlsoap.org/soap/encoding/:string' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.; targetException=java.lang.IllegalArgumentException: No Deserializer found to deserialize a 'http://schemas.xmlsoap.org/soap/encoding/:string' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.]

I’ve tried messing around with SOAPMappingRegistry, but it seems to make no difference at all, I added the lines:

SOAPMappingRegistry smr = new SOAPMappingRegistry();

StringDeserializer sd = new StringDeserializer();

smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName("", "sayHelloReturn"), null, null, sd);

cl.setSOAPMappingRegistry(smr);

But it made no difference. I know I’m getting a valid response from my Web Service, the xml that comes back from the call looks like:

<?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>

<ns1:sayHelloResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="urn:dohello">

Hello Ben, aged 26

</sayHelloReturn>

</ns1:sayHelloResponse>

</soapenv:Body>

</soapenv:Envelope>

It just seems that my client can’t unwrap it properly to give me the result.

I can’t find anywhere that seems to provide me with enough detail to identify the root of my problem. Can anyone help?

Ben

P.S. Are there any plans to put functionality into Axis so that complex types can be easily passed around to other platforms? (I know there’s some bean stuff, but what about collections etc.?)
