Brian Etheridge commented on AXIS2-3229:
----------------------------------------
Hi,
A bit more information. I think this could be due to running the
wsdl2java command against a wsdl which has references to 'localhost',
where the directories and/or resources referenced do not exist.
In my example, I have the following section in the wsdl which gave me
the null pointer exception:
...
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
targetNamespace="http://localhost/xxx/yyy/zzz/getData";
xmlns:tns="http://localhost/xxx/yyy/zzz/getData";
xmlns:SOAP_ENC="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/";>
...
When I changed this to reference a server with those directories
available I didn't get the null pointer exception; I got an error but at
least the program didn't crash.
Hope that helps.
Brian
