Re: Help needed with services that need errorMessageList to bedeserialized

[Jacques Le Roux <ja...@les7arts.com>]

Look for SOAP into FAQ. Notably 
http://docs.ofbiz.org/display/OFBIZ/Export+Ofbiz+Services+that+use+complex+type+parameters+via+SOAP+using+AXIS2
I have still to integrate it in OFBiz, but it's not my priority...

Good day.

I am still new to Ofbiz and need some help/suggestions regarding calling services (as webservices) that need Deserializing.

My aim is to be able to call ofbiz services from an external server. In my investigation into this, I used the createUserLogin
service in Ofbiz to test this.
It works fine, when I try to create a new userlogin, but when I try to create a user login that already exists, an errorMesssageList
is returned that causes the
following exception on the external server:

org.xml.sax.SAXException: Deserializing parameter 'errorMessageList':  could not find deserializer for type
{http://www.w3.org/2001/XMLSchema}any


How do I deserialize the errorMessageList parameter? Any help/suggestions will be appreciated since I am also new to SOAP services.



Here is the steps and code that I used:

1. Export the createUserLogin service in Ofbiz by setting export=true. This makes the service available as a SOAP service. To force
authentication on user creation, the auth=true parameter
was added.

   <service name=createUserLogin engine=java auth=true
        location=org.ofbiz.common.login.LoginServices invoke=createUserLogin export=true>
        <description>Create a UserLogin</description>
        <attribute name=userLoginId type=String mode=IN optional=false/>
        <attribute name=enabled type=String mode=IN optional=true/>
        <attribute name=currentPassword type=String mode=IN optional=false/>
        <attribute name=currentPasswordVerify type=String mode=IN optional=false/>
        <attribute name=passwordHint type=String mode=IN optional=true/>
        <attribute name=requirePasswordChange type=String mode=IN optional=true/>
        <attribute name=externalAuthId type=String mode=IN optional=true/>
        <attribute name=partyId type=String mode=IN optional=true/>
    </service>

2. Call the SOAP service  from the external server by using Axis:

Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new URL(http://localhost:8080/webtools/control/SOAPService));      //this will be an external url.
local for testing

QName queryName = new QName(createUserLogin,createUserLogin);

call.setOperationName(queryName);
call.addParameter(userLoginId, org.apache.axis.Constants.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
call.addParameter(currentPassword, org.apache.axis.Constants.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
call.addParameter(currentPasswordVerify, org.apache.axis.Constants.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
call.addParameter(login.username, org.apache.axis.Constants.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
call.addParameter(login.password, org.apache.axis.Constants.XSD_STRING, javax.xml.rpc.ParameterMode.IN);
call.setReturnType(org.apache.axis.Constants.XSD_ANY);

try{
                 Object response = call.invoke(new Object[]{louis17,pass111111,pass111111,admin,ofbiz});
System.out.println(Response of creating a user + response);
}
catch (Exception e){
System.out.println(error + e.getMessage());
}


3. If the user doesn't exist yet, a success message is returned. If the user already exists the following exception on the external
server occurs:

ERROR [org.apache.axis.client.Call] Exception:
org.xml.sax.SAXException: Deserializing parameter 'errorMessageList':  could not find deserializer for type

error ; nested exception is:
org.xml.sax.SAXException: Deserializing parameter 'errorMessageList':  could not find deserializer for type
{http://www.w3.org/2001/XMLSchema}any


How do I get pass this problem, since I would rather by able to see on the client side the cause of the error -  Could not create
login user: user with ID louis17 already exists. How do I
deserialize errorMessageList? Any help would be appreciated.


Regards.
