SimpleAsmxClient
  
  
Test 1:  
Step 1: Run Java Client 
  
Results: 3 of the 4 Prints are successful 
  
Send Address to Service... 
  
System.Web.Services.Protocols.SoapException: Server was unable to read request. ---> 
System.InvalidOperationException: There is an error in XML document (1, 337). ---> 
System.InvalidOperationException: 
The specified type is abstract: name='Address', namespace='urn:emp:data', at 
<Address xmlns='urn:emp:data'>. 
  
Test 2: 
Step 1: Modify Person.java 
Change all instance of 
data.emp.Address 
To 
data.emp.HomeAddress 
  
Step 2: Run Java Client 
  
Results: 4 of the 4 Prints are successful 
  
  
  
  

SimpleAsmxXFireClient
  
  
Test 1:  
Step 1: Run Java Client 
  
Results: 3 of the 4 Prints are successful 
   
            Starting GetWorkAddress()... 
            java.lang.ClassCastException: emp.data.HomeAddress 
  
  
Test 2: 
   
Step 1: Modify SimpleAsmxService.asmx 
Change 
[WebMethod] 
public List<HomeAddress> GetHomeAddress() 
To 
// [WebMethod] 
public List<HomeAddress> GetHomeAddress() 
  
Step 2: Rebuild Java Proxy Classes 
  
Step 3: Comment out code in Java Client 
GetWorkAddress(); 
  
public static void GetWorkAddress() 
{ 
... 
} 
  
public static void Print( ArrayOfHomeAddress listOfAddress ) 
{ 
... 
} 
  
Step 4: Run Java Client 
  
Results: 2 of the 3 Prints are successful 
public static void GetAddress() fails to retrieve data 
  
org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. 
Nested exception is org.codehaus.xfire.fault.XFireFault: Could not unmarshall type. 
  
Test 3: 
Step 1: Restore original files 
·         SimpleAsmxService.asmx 
·         SimpleAsmxXFireClient.java 
  
Step 2: Modify SimpleAsmxService.asmx 
Uncomment the following method 
  
[WebMethod] 
public List<WorkAddress> GetMatchingTypes() 
{ 
... 
} 
   
  
Step 3: Rebuild Java Proxy Classes 
  
Step 4: Run Java Client 
  
Results: 4 of the 4 Prints are successful
