soap4r and java data types

[Don Hill]

Is there any way using soap4r and wsdl2rb to use java Map. I ran wsdl2rb
and it generates fine but when I try and use the service I get the
following error.

#<SOAP::Mapping::Object:0x7fe6dec4>: could not find a type with qname
http://www.ruby-lang.org/xmlns/ruby/type/custom:Ma
p (SOAP::FaultError)

The entry from the wsdl looks like this.

<schema
targetNamespace="http://www.themindelectric.com/package/java.util/">
<complexType name="Map" abstract="true"/>
</schema>

any suggestions
