The AXIS engine could not find a target service to invoke

[vijay saraf]

Hi All,

I stucked with Axis 1.3 (please don't ask why 1.3...) and JDK 1.5 with webshpere.
i have very basic service 'Calculator' with two operations 'add' and 'subtract'
here is my server-config.wsdd file (placed under WEB-INF directory).

<!-- Use this file to deploy some handlers/chains and services --> <!-- Two ways to do this: --> <!-- java org.apache.axis.client.AdminClient deploy.wsdd --> <!-- after the axis server is running --> <!-- or --> <!-- java org.apache.axis.utils.Admin client|server deploy.wsdd --> <!-- from the same directory that the Axis engine runs --> <deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"> <!-- Services from CalculatorService WSDL service --> <service name="Calculator" provider="java:RPC" style="wrapped" use="literal"> <parameter name="wsdlTargetNamespace" value="urn:com.test"/> <parameter name="wsdlServiceElement" value="CalculatorService"/> <parameter name="wsdlServicePort" value="Calculator"/> <parameter name="className" value="com.test.generated.CalculatorSoapBindingImpl"/> <parameter name="wsdlPortType" value="Calculator"/> <parameter name="typeMappingVersion" value="1.2"/> <wsdlFile> /wsdl/Calculator/Calculator.wsdl </wsdlFile> <operation name="add" qname="operNS:add" xmlns:operNS="urn:com.test" returnQName="addReturn" returnType="rtns:int" xmlns:rtns="http://www.w3.org/2001/XMLSchema" soapAction="urn:add" > <parameter qname="in0" type="tns:int" xmlns:tns="http://www.w3.org/2001/XMLSchema"/> <parameter qname="in1" type="tns:int" xmlns:tns="http://www.w3.org/2001/XMLSchema"/> </operation> <operation name="subtract" qname="operNS:subtract" xmlns:operNS="urn:com.test" returnQName="subtractReturn" returnType="rtns:int" xmlns:rtns="http://www.w3.org/2001/XMLSchema" soapAction="urn:subtract" > <parameter qname="in0" type="tns:int" xmlns:tns="http://www.w3.org/2001/XMLSchema"/> <parameter qname="in1" type="tns:int" xmlns:tns="http://www.w3.org/2001/XMLSchema"/> </operation> <parameter name="allowedMethods" value="add subtract"/> </service> </deployment>

and here is my wsdl file.

<?xml version="1.0" encoding="UTF-8"?> <wsdl:definitions targetNamespace="http://" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://" xmlns:intf="http://" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <!--WSDL created by Apache Axis version: 1.3 Built on Oct 05, 2005 (05:23:37 EDT)--> <wsdl:message name="subtractRequest"> <wsdl:part name="in0" type="xsd:int"/> <wsdl:part name="in1" type="xsd:int"/> </wsdl:message> <wsdl:message name="subtractResponse"> <wsdl:part name="subtractReturn" type="xsd:int"/> </wsdl:message> <wsdl:message name="addRequest"> <wsdl:part name="in0" type="xsd:int"/> <wsdl:part name="in1" type="xsd:int"/> </wsdl:message> <wsdl:message name="addResponse"> <wsdl:part name="addReturn" type="xsd:int"/> </wsdl:message> <wsdl:portType name="Calculator"> <wsdl:operation name="add" parameterOrder="in0 in1"> <wsdl:input message="impl:addRequest" name="addRequest"/> <wsdl:output message="impl:addResponse" name="addResponse"/> </wsdl:operation> <wsdl:operation name="subtract" parameterOrder="in0 in1"> <wsdl:input message="impl:subtractRequest" name="subtractRequest"/> <wsdl:output message="impl:subtractResponse" name="subtractResponse"/> </wsdl:operation> </wsdl:portType> <wsdl:binding name="CalculatorSoapBinding" type="impl:Calculator"> <wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> <wsdl:operation name="add"> <wsdlsoap:operation soapAction="urn:add"/> <wsdl:input name="addRequest"> <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://" use="encoded"/> </wsdl:input> <wsdl:output name="addResponse"> <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://" use="encoded"/> </wsdl:output> </wsdl:operation> <wsdl:operation name="subtract"> <wsdlsoap:operation soapAction="urn:subtract"/> <wsdl:input name="subtractRequest"> <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://" use="encoded"/> </wsdl:input> <wsdl:output name="subtractResponse"> <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://" use="encoded"/> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="CalculatorService"> <wsdl:port binding="impl:CalculatorSoapBinding" name="Calculator"> <wsdlsoap:address location="http://localhost:9080/TestService/services/Calculator"/> </wsdl:port> </wsdl:service> </wsdl:definitions>

when i try to invoke the service with simple client i am getting following error

AxisFault
faultCode: {http://xml.apache.org/axis/}Server.NoService
faultSubcode:
faultString: The AXIS engine could not find a target service to invoke! targetService is null
faultActor:
faultNode:
faultDetail:
{http://xml.apache.org/axis/}hostname:My_Host_Name

I am failed here to figure-out the problem.
for info,
i am getting expected results when i follow the urls
http://localhost:9080/TestService/services/Calculator
as
Hi there, this is an AXIS service!
Perhaps there will be a form for invoking the service here...

but when go to http://localhost:9080/TestService/servlet/AxisServlet and click the wsdl link (in actual it is http://localhost:9080/TestService/services/Calculator?wsdl) i am getting error messgae as
AXIS error
Could not generate WSDL!
There is no SOAP service at this location

Here is my web.xml file.

Ahh....

I got the problem...
My URLMapper was missing...
here is my new server-config.wsdd file

<!-- Use this file to deploy some handlers/chains and services --> <!-- Two ways to do this: --> <!-- java org.apache.axis.client.AdminClient deploy.wsdd --> <!-- after the axis server is running --> <!-- or --> <!-- java org.apache.axis.utils.Admin client|server deploy.wsdd --> <!-- from the same directory that the Axis engine runs --> <deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"> <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper" /> <!-- Services from CalculatorService WSDL service --> <service name="Calculator" provider="java:RPC" style="wrapped" use="literal"> <parameter name="wsdlTargetNamespace" value="urn:com.test"/> <parameter name="wsdlServiceElement" value="CalculatorService"/> <parameter name="wsdlServicePort" value="Calculator"/> <parameter name="className" value="com.test.generated.CalculatorSoapBindingImpl"/> <parameter name="wsdlPortType" value="Calculator"/> <parameter name="typeMappingVersion" value="1.2"/> <wsdlFile> /wsdl/Calculator/Calculator.wsdl </wsdlFile> <operation name="add" qname="operNS:add" xmlns:operNS="urn:com.test" returnQName="addReturn" returnType="rtns:int" xmlns:rtns="http://www.w3.org/2001/XMLSchema" soapAction="urn:add" > <parameter qname="in0" type="tns:int" xmlns:tns="http://www.w3.org/2001/XMLSchema"/> <parameter qname="in1" type="tns:int" xmlns:tns="http://www.w3.org/2001/XMLSchema"/> </operation> <operation name="subtract" qname="operNS:subtract" xmlns:operNS="urn:com.test" returnQName="subtractReturn" returnType="rtns:int" xmlns:rtns="http://www.w3.org/2001/XMLSchema" soapAction="urn:subtract" > <parameter qname="in0" type="tns:int" xmlns:tns="http://www.w3.org/2001/XMLSchema"/> <parameter qname="in1" type="tns:int" xmlns:tns="http://www.w3.org/2001/XMLSchema"/> </operation> <parameter name="allowedMethods" value="add subtract"/> </service> <transport name="http"> <requestFlow> <handler type="URLMapper" /> </requestFlow> </transport> </deployment>

Well...........thanks all.
