Andrew Teirney commented on AXIS-2386:
--------------------------------------

I myself have just come across this problem, i saw it a while back but didn't take any notice
of it. I have been doing a bit of research today axis 1.1 seems to be fine, however 1.2.1
and 1.3 are both affected, and what is in the latest snapshot to the best of my knowledge.
I don't know the exact logic that is used to generate the wsdl, but from what i can see it
looks at the XmlType and depending on whether that type has already been defined it will take
extra action such as defining the array of the objects. From a java class that has associated
metadata through the wsdl2java process i get the following...

> Java2WSDL changes type double array into a single double.
> This happens when you run Java2WSDL manually on the command line or when a wsdl file
is generated from a service_name?wsdl url.
> Currently to fix this I just manually edit the generated WSDL file and distrobute that.
> The Java code originally came from a hand made WSDL file. WSDL2Java was used to generate
the Java code. The section that is affected by this problem is the 'ValueVector' complexType
which contains and element 'values' which is an array of doubles. After converting to Java
and then back to WSDL 'values' becomes a single double.
