I would like to report that currently when generating axis2 classes from wsdl, if the wsdl includes other files like this:
<import namespace="http://example.com/types" location="otherFile.wsdl"/>
Then the wsdl2java will not be able to locate the other files.
If I run wsdl2java -uri <the wsdl file> it does manage to find the other files and generate the classes correctly.
