Access OFBiz webservice from external java client

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>

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;
}
}

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 + ")")
}
}

The wsdl hence generated is :

<?xml version="1.0" encoding="UTF-8"?>

</wsdl:port>
</wsdl:service>
</wsdl:definitions>

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 :

(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

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();

result.put("outputList", inputList);

Re: Access OFBiz webservice from external java client

Hi,

I have made modifications in ModelParam.java due to tha fact that supports
the java to wsdl conversion of only primitive data types and not complex
types like Map or List.
If i do not make changes into it, wsdl file does not get generated...

Re: Access OFBiz webservice from external java client

Administrator

I'm sorry for you but some has succedded using this method (at least Paul Piper)
I'm still currently working (from time to time) on implenting this method in the framework, but I think there are already enough
information there to make it work.
BTW, please could you keep your message less verbose ?
