return type from Web Service
Hi,
I have little knowledge on Axis2 and just started working on it few
days back.
At present I am trying to develop web service that will basically
interact the business methods and return it back as bean to client.
Something like:
----------------------
Client <----- | | -----> Web Service Interface <-----> Actual business
method
I am using RPCMessageReceiver for this purpose.
My business methods are already fixed and most of them are returning
Java Collection type object as return type. Presently I am trying to create
a web service layer that will get the Collection type object from business
method, then I am setting collection object in a bean and returning the bean
from the web service method.
Structure of the bean
---------------------------------
public class SampleBean{
Set set;
public void setData(Set set){
this.set = set;
}
public Set getData(){
return set;
}
}
In my Service Class
------------------------------
public class TestService{
public SampleBean getAddres(){
//Get the collection from the business method
Set set = invoke business method
SampleBean sampleBean = new SampleBean();
// Set the collection in a bean.
sampleBean.setData(set);
return sampleBean;
}
}
But doing so I am facing this exception:
Jan 27, 2007 10:15:02 AM
org.apache.axis2.rpc.receivers.RPCMessageReceiver invokeBusinessLogic
SEVERE: Exception occurred while trying to invoke service method
getAdrresses
org.apache.axiom.om.OMException: java.lang.IllegalArgumentException:
null rcl
at
org.apache.axiom.om.impl.builder.StAXOMBuilder.next(StAXOMBuilder.java
I know there are some issues with Collection in Axis2. If so, is there any
other alternative way/approach in Axis2 to solve this problem?
Regards,
Raja
