Hi,
I am trying to access OFBiz webservice from external java client.
I have successfully accessed OFBiz web service with primitive types as
parameters from external client and vice versa but i am stuck up with
accessing a service having Map or List as arguments...
For this;
I made an OFBiz service and defined it in services.xml :
<service name="ComplexInputService" engine="java" export="true"
location="org.ofbiz.ExtWebServiceClient.ComplexInputService"
invoke="callWebService">
<description>web service with complex params</description>
<attribute type="List" mode="IN" name="inputList" optional="true"
/>
<attribute type="List" mode="OUT" name="result" optional="true"/>
</service>
Make below given modification in you service definition:
<service name="ComplexInputService" engine="java" export="true"
location="org.ofbiz.ExtWebServiceClient.ComplexInputService"
invoke="callWebService">
<description>web service with complex params</description>
<attribute type="List" mode="IN" name="inputList" optional="true"
/>
<attribute type="List" mode="OUT" name="outputList"
optional="true"/>
</service>
The web service inside OFBiz is :
public class ComplexInputService {
public static Map callWebService(DispatchContext ctx, Map context) {
System.out.println("inside call web service.........");
Map<String, Object> result = ServiceUtil.returnSuccess();
List inputList = (List)context.get("inputList");
result.put("result", inputList);
System.out.println("service finished......");
return result;
}
}
Make below given modification in your service implementation:
public class ComplexInputService {
public static Map callWebService(DispatchContext ctx, Map context) {
System.out.println("inside call web service.........");
Map<String, Object> result= FastMap.newInstance();
List<String> outputList= FastList.newInstance();
List<String> inputList=
UtilGenerics.checkList(context.get("inputList"));
result.put("outputList", inputList);
result = ServiceUtil.returnSuccess();
System.out.println("service finished......");
return result;
}
}
OFBiz framework restricted the wsdl file from being generated, due to the
fact that the input and output parameters for the service are List. I
modified ModelParam.java
(framework/service/src/org/ofbiz/service/ModelParam.java), to support
complx parameters also..
public class ModelParam implements Serializable {
.
.
protected String java2wsdlType() throws WSDLException {
// If statements to support primitive types as arguments to web
service
if (ObjectType.instanceOf(java.lang.Character.class, this.type)) {
return "string";
} else if (ObjectType.instanceOf(java.lang.String.class, this.type
)) {
return "string";
}
.
.
. // added more if statements to support Map and List
else if (ObjectType.instanceOf(java.util.AbstractMap.class, this.
type)) {
System.out.println("service takes map as input param.......");
return "anyType"; // i am not getting any idea what to return
so that client can read the wsdl properly
}
else if (ObjectType.instanceOf(java.util.AbstractList.class, this.
type)) {
System.out.println("service takes List as input param......."
);
return "anyType";
}
throw new WSDLException(WSDLException.OTHER_ERROR, "Service cannot
be described with WSDL (" + this.name + " / " + this.type + ")")
}
}
Discard this changes. These are useless, when you use above given
improved code.
The wsdl hence generated is :
<?xml version="1.0" encoding="UTF-8"?>

<wsdl:message name="ComplexInputServiceRequest">
<wsdl:part name="inputList" type="xsd:anyType"/>
</wsdl:message>
<wsdl:message name="ComplexInputServiceResponse">
<wsdl:part name="result" type="xsd:anyType"/>
</wsdl:message>
<wsdl:portType name="ComplexInputServicePortType">

<wsdl:service name="ComplexInputService">

</wsdl:port>
</wsdl:service>
</wsdl:definitions>
Change your wsdl part's name according to above given modifications
I have created a java client in eclipse outside OFBiz
public static void main(String[] args)
{
try
{
String endPoint =
"http://localhost:8088/webtools/control/SOAPService";;
Call call = (Call)new Service().createCall();
call.setTargetEndpointAddress(new URL(endPoint));
call.setOperationName(new
QName("http://ofbiz.apache.org/service/","ComplexInputService";));
System.out.println("*******call.add parameterl********");
List inputList = new Vector();
inputList.add("neha");
inputList.add("mehta");
call.addParameter("inputList",org.apache.axis.Constants.SOAP_VECTOR,
javax.xml.rpc.ParameterMode.IN);
call.addParameter("outputList",org.apache.axis.Constants.SOAP_VECTOR,
javax.xml.rpc.ParameterMode.OUT);
call.setReturnType(org.apache.axis.Constants.SOAP_VECTOR);
System.out.println("*******call invoking********");
Object responseWS=call.invoke(new Object[]{inputList});
Map output = call.getOutputParams();
System.out.println("call invoked...");
}
catch(Exception exp)
{
exp.printStackTrace();
}
}
I get an exception on running the client :
AxisFault

On OFbiz server, i get an exception as:

(org.xml.sax.SAXException cannot be cast to java.lang.String).
I am not able to understand how to go ahead... I am stuck up completely...
Kindly help me out
