Title: java.util.Map, List with wingfoot SOAP client and Axis beta 2 server

Martin:

Thanks for pointing this out. I verified that Axis does complain it each element of the Hashtable is decorated with mapitem instead of item. I am baffled as to why it exhibits this behaviour (Apache does not complain); we will change mapitem to item in our next release to ensure full compatibility with Axis.

Regards,

Kal

Hi,

I noticed on compatibility test results on the wingfoot site that wingfoot SOAP is shown as fully compatible with Apache Axis. I was wondering if wingfoot soap1.02 with J2SE transport supports the use of Maps and Lists as parameters and return types against Axis beta 2? I'm running Axis beta 2 and have a service published with the following interface:

public Map getProfile(String type, Map ids);

and when I run a wingfoot client making this call against Axis the following SAXException occurs on the server:

[ERROR,AxisServlet] Exception:
org.xml.sax.SAXException: Bad types (null -> interface java.util.Map)

If I try to use a Hashtable as the actual value for the parameter passed instead of a HashMap, I get a slightly different exception:

[ERROR,AxisServlet] Exception:
org.xml.sax.SAXException: Only ''item'' elements are allowed in a Map!
org.xml.sax.SAXException: Only ''item'' elements are allowed in a Map!

        at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)

It seems in this case that wingfoot is using <mapitem> tags for each element in the Hashtable, and Axis is expecting <item> tags?? Any help/suggestions appreciated.

Thanks,
