about serialization/deserialization of complex types using the WSDL2Java

[jiadao]

hello:     I have one problem when I want to do the  the serialization/deserialization  using the xml<->Java datatypes mapping, when I try to extension the types which are defines by myself For examples        Targetnamespace=”foo”      <xs:complexType name="Named">             <xs:simpleContent>                   <xs:extension base="foo:StateType">                         <xs:attribute name="Name" type="xs:string"/>                   </xs:extension>             </xs:simpleContent>       </xs:complexType>       <xs:simpleType name="StateType">             <xs:restriction base="xs:string">                   <xs:enumeration value="value1"/>                   <xs:enumeration value="value2"/>                   <xs:enumeration value="value3"/>             </xs:restriction>       </xs:simpleType> there are some errors java org.apache.ax is.wsdl.WSDL2Java example.wsdl java.io.IOException: Type Named is referenced but not define d.         at org.apache.axis.wsdl.symbolTable.SymbolTable.checkForUndefined(Symbol Table.java:522)         at org.apache.axis.wsdl.symbolTable.SymbolTable.add(SymbolTable.java:422 )         at org.apache.axis.wsdl.symbolTable.SymbolTable.populate(SymbolTable.jav a:408)         at org.apache.axis.wsdl.symbolTable.SymbolTable.populate(SymbolTable.jav a:393)         at org.apache.axis.wsdl.gen.Parser$WSDLRunnable.run(Parser.java:245)         at java.lang.Thread.run(Unknown Source)   sounds like that it is wrong to do the extension using the self-defined type which is not the XSD intrinsic types.   Thank u very much in advance!   jiadao
