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](http://www.ruby-lang.org/xmlns/ruby/type/custom:Ma)  
p (SOAP::FaultError)

The entry from the wsdl looks like this.

any suggestions
