Exception classes generated using Axis2 wsdl2java don't extend Exception - exception

Question

I'm trying to generate a client using wsdl2java. The wsdl is as follows:
<?xml version="1.0" encoding="UTF-8"?>

The issue I'm finding if that want to unpack the classes (using option -u), the class AdminServiceException does not extend java.lang.Exception, and therefore the code doesn't compile, since that it can not throw that class. So the situation is like this:
If I pack the classes(no option -u), the class is defined as follows:
public class AdminServiceException extends java.lang.Exception{....}
but if I use option -u, the class is generated as follows:
public class AdminServiceException
implements org.apache.axis2.databinding.ADBBean{....}
which is not correct, since it can not be thrown. Any ideas?
EDIT:
I just modified the WSDL to make it simplier. It's as follows:

I created the code using wsdl2java as follows:
/opt/eco/ecoprd/axis2-1.6.1/bin >> ./wsdl2java.sh -u -uri test2.wsdl -or
Using AXIS2_HOME: /opt/eco/ecoprd/axis2-1.6.1
Using JAVA_HOME: /usr/local/jdk1.6.0_16
Retrieving document at 'test2.wsdl'.
But when I try to compile the code:
/opt/eco/ecoprd/axis2-1.6.1/bin >> javac -cp $CLASSPATH src/com/rsa/csd/ws/admin/*.java
src/com/rsa/csd/ws/admin/Fault.java:95: cannot find symbol

Answer 1

I tried generating client with your 2nd wsdl using Eclipse IDE. It generated and compiled all well. That means wsdl is good to go.
Generated AdminServiceException.java
public class AdminServiceException extends java.lang.Exception{
private static final long serialVersionUID = 1333311238212L;
private com.rsa.csd.ws.admin.UserAdminServiceServiceStub.Fault faultMessage;
public AdminServiceException() {
super("AdminServiceException");
}
public AdminServiceException(java.lang.String s) {
super(s);
}
public AdminServiceException(java.lang.String s, java.lang.Throwable ex) {
super(s, ex);
}
public AdminServiceException(java.lang.Throwable cause) {
super(cause);
}
public void setFaultMessage(com.rsa.csd.ws.admin.UserAdminServiceServiceStub.Fault msg){
faultMessage = msg;
}
public com.rsa.csd.ws.admin.UserAdminServiceServiceStub.Fault getFaultMessage(){
return faultMessage;
}
}
For command line use : ./wsdl2java.sh -g -ssi -uri test2.wsdl
You don't have to mention -u, it will generate seperate classes for databinders implementing binding you have used.

Answer 2

wsdl2java should have generated a skeleton class and/or interface for the service class. Check the skeleton to see how the relevant service functions are declared. You'll probably find that they are declared to throw something like AdminServiceExceptionException. For some reason, Axis2 creates one class based on the definition of the fault in the WSDL, then another class extending Exception which acts as a container for the first class.

Answer 3

Just in case you are using JAXB data binding (JAXBRI), you have to make sure that your wsdl:message name (AdminServiceException) in the following element:
<wsdl:message name="AdminServiceException">
<wsdl:part element="impl:fault" name="fault"/>
</wsdl:message>
is different from element name (impl:fault). In your case they actually are different.
Otherwise you will get your "AdminServiceException does not extend java.lang.Exception" error.
