Hi people,
I am really puzzled about Axis Code generators and the way custom exceptions
are passed. I do not even find good documentation on it. I've been on this
problem for almost a week now, and still do not find any answer. My problem: I
can invoke web services without problems, but I do not get back customized
exceptions on my Java client side.
Here is my generation procedure and source:
1) I write a class AService, in which I define one simple operation
(add(int,int,int)), it returns a result of type long, if the third argument is
0. If the 3rd int is not 0, it will throw "CustomException".
2) "CustomException" is a class defined as extending java.lang.Exception and
implements java.io.Serializable
3) I generate the service with Axis2 tools, and deploy the service.
4) I generate the wsdl. The wsdl correctly includes the fault element named
<wsdl:fault name="CustomException">
<soap:fault use="literal" name="CustomException"/>
5) I generate the java client with the axis2 codegen wizard.
6) I invoke the web service with it, without exception testing: works.
7) I invoke it to throw the exception (3rd int = 1): doesn't work. I only get
an AxisFault. But the generated client should throw a CustomException.
AxisFault.getDetail() is empty.
What is wrong ?
I include the 2 simple java files from which I started here:
package com.foo.bar;
public class AService {
public long Add(int a, int b, int exceptionThrown) throws
CustomException {
if (exceptionThrown != 0) {
System.out.println("CustomException to b
instantiated");
CustomException e = new CustomException();
e.setCustomMsg("bar");
throw e;
}
return a+b;}
}
Here the exception class:
package com.foo.bar;
import java.io.Serializable;
public class CustomException extends java.lang.Exception implements
Serializable {
private static final long serialVersionUID = 1542353156105984960L;
private String customMsg;
public String getCustomMsg() {return customMsg;}
public void setCustomMsg(String customMsg) {this.customMsg=customMsg;}
}
Here is the generated WSDL:
