Hello,
I am using AXIS 1.2beta 3.
I will post the server side code, the .wsdd (the wsdl is autogenerated by axis using
the wsdd parameters), and then will try to give a walkthrough what to change in the
.NET generated code (using wsdl.exe or Add WebReference) and why it had to be changed.
Forgive that I am posting C# code on this list.
I used the wrapped (doc/literal with rpc method name wrapping convention) style. It
also works with pure doc/lit (if you want information on that let me know) and put in
my HashMap only strings which was enough for the service I had to invoke, I also just
tested it with String[], so it should work with int[] and so on, and maybe with a
JavaBean[], but I am not sure about that. The knwon problems sending arrays and
receiving them with .net apply yet there will be now schema definition for the type
you are receiving with anytype, so you have to use reflection to find out what the
things are the XmlSerializer produced or know before hand what you will receive.
//server side code
//----------------
package testhashmapservicealldoc;
public class TestHashMapService {
public HashMap sayHashMap (String in)
{
HashMap h = new HashMap();
String[] t = new String[] {"one", "one2", "one3", "one4"};
h.put("key 1", t);
h.put("key 2", "two");
h.put("key 3", "three");
h.put("key 4", in);
return h;
}
}

----------------------
So there had to be three changes for it to work:
- the namespace of sayHashMapReturn element is ""; this is incorrect according to the
wsdl it should be "http://testhashmapservicealldoc";
- the namespace of the item element in the return is "" so we need to change this
(weather this is a wrong interpretation of .NET or AXIS according to the schema, I am
not sure, from my opinion and the reading of the schema in the wsdl the namespace of
item should be "" and also the in the previous problem it should be "" since both are
child elements of and they are understood to be in the namespace "")
- the namespace of the mapitem class also needs to be changed to "" (same discussion
as above; though the type Map is in the namespace "http://xml.apache.org/xml-soap"; the
elements key and value are not in the namespace)
Can anyone comment on the namespace thing, for clarification what is the right (if you
need the wsdl which has the schema def run the compiled .java code through
java org.apache.axis.wsdl.Java2WSDL -y WRAPPED -u LITERAL
testhashmapservicealldoc.TestHashMapService -l http://foo)
Okay that it,
