Dear all,
I am a new Axis2 user. Today I got a weird exception when calling a Web
service.
This Web service is deployed on Tomcat/Axis2. I need to transmit an object
(parameter) to it. The object contains a String attribute. The object is
received correctly. However, when calling a local method on the remote
machine, it got the following errors. I noticed that the method
SelectCategoriedHubByKey(Ljava/lang/String key) cannot be found on the
machine. Actually, the method should be SelectCategoriedHubByKey(String
key). Why is the parameter changed from String to LJava/lang/String? How to
solve the problem?
Thanks so much!
LB
