RE: AxisFault and CustomException
Hi Pär,
I am also quite dazzled. At least in Axis2 1.2, the exception class generated
for the service implements serialization methods, and in fact there are
Hundreds () of lines of code for just a simple service.
I do not know if this is the way to go. For a simple service just doing an
addition of two numbers, and having 3 kinds of exceptions thrown, this is
somewhat absurd (I pasted the code to a word document - 157 pages...).
I don't think that component-code (business logic) should be mixed with code
specfici to the Axis2 framework. I think that what WSDL2JAVA does should in
fact for the most be generated and handled at runtime, or when the service is
deployed - but all of this should be kept hidden to the developer. Also, when
looking at the client code, it is just overbloated with
service-/xml-/axis-specific code.
I am now investigating methods to call webservices through EJB/JBoss via a
stateless session facade. I hope to see a cleaner separation of business logic
and technical code there.
Keep me updated with your results, thanks in advance,
Jay

Subject: AxisFault and CustomException
Hello!
I have created a simple Axis2 service called MyService, se code below. It has
one method: addOneToPositiveValue. If it is called with a negative value it
throws a CustomException.
I have created a MyService.aar and deployed it on Axis2 1.3 and Tomcat 5.5.23
Then I created a simple client with wsdl2java and xmlbeans style.
Its really hard to get the CustomException in an easy way at the client side.
The AxisFault.getDetail() displays the name of the exception deep down in some
kind of stacktrace. Thats all.
Can you Axis2 gurus have a look at it please?
If I haven't missed anything I think something has to be done to make this
easier.
Thanks.

RE: AxisFault and CustomException
Hi
I'm not yet Axis2 guru, but i think i understand your problem :-)
When the java method of your service throws a method, axis translates the java
exception into a soap fault. Soap fault is less structured than a java
exception. It has only a soap:code and a soap:reason. Both are text elements.
By default, axis sets this text to the value of the stack trace of the java
exception (look at comments at the beginning of axis2.xml).
Then, when your client catches the soap fault, it raises an AxisFault, which is
a java exception, but you have lost the structure, because of the fact that
there is no equivalent in soap to the very structured java exception.
getDetail() just gives you soap element which contains the code and the reason.
For myself, I would not use a soap fault, but encapsulate the result type of my
method in a wrapper which contains an error code (one of the codes means that
result ok). If the method fails, the error code gives you the exception and the
wrapper object would be null:
package axis2test;
public class MyService {
public MyService() {
}
public MyDataType addOneToPositiveValue(int value) throws CustomException {
MyDataType result = new MyDataType();
if(value 1) {
result.setErrorCode(1);
return 0;
}
else {
result.setErrorCode(0)
return(value + 1);
}
}
}
package axis2test;
public class MyDataType {
private int data;
private int errorCode;
public getters, setters,...
}
