Sending Map to a server
In my service, I have a method that accepts a Map as a parameter:
public MyObject serviceMethod(Map values) {
// impl...
}
I used Axis to auto generate the WSDL for it and it did generate:
<s:schema targetNamespace="http://xml.apache.org/xml-soap">
<s:import namespace="http://schemas.xmlsoap.org/soap/encoding/" />
<s:complexType name="Map">
<s:sequence>
<s:element minOccurs="0" maxOccurs="unbounded" name="item">
<s:complexType>
<s:all>
<s:element name="key" type="s:anyType" />
<s:element name="value" type="s:anyType" />
</s:all>
</s:complexType>
</s:element>
</s:sequence>
</s:complexType>
<s:element name="Map" nillable="true" type="s1:Map" />
For it (namespaces for tags are a little different, but shouldn't be an
issue).
I'm getting the error:
Caused by: org.xml.sax.SAXException: Bad types (class [Ljava.lang.Object; ->
int
erface java.util.Map)

When I try to run this. The client is sending (using tcpmon):
<?xml version='1.0' encoding='utf-8'?>

<key xsi:type="xsd:string">PARAMETERS_2</key>
<value
xsi:type="xsd:string"></value></item></values></mswsb:enter></SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Is what the client is sending wrong, and if so, what should it be sending?
I tried to add a typeMapping in server-config.wsdl:
<typeMapping
xmlns:ns="http://xml.apache.org/xml-soap"
qname="ns:Map"
type="java:java.util.Map"
serializer="org.apache.axis.encoding.ser.MapSerializerFactory"
deserializer="org.apache.axis.encoding.ser.MapDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>
But that didn't help.
Thanks!

Re: Sending Map to a server

Maps are not typesafe. While it is possible to get it to work, I don't
think you want to send a non-typesafe component over a webservice. It
would open the door to errors. XML-RPC works the best when your types
are expiclity declared. I would avoid anyType declarations. Usually
they can be avoided.
Might I suggest you change your design and use an array of JavaBeans as
your "values" argument.
public class MyBean (
private String key;
private String value;
// With your getters and setters below.
)
public MyObject serviceMethod(MyBean[] values) {
