Question

I have a JAXB schema where one class contains a list of another class. The schema is given below.

But whenever I create the java classes from this schema , the method is not using generics so I have to use the casts just like pre java 5 way.

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:common="glodas.research">

… The method is generated like this

    java.util.List getBitAge();

I want the java method to be generated like this

java.util.List<BitAge> getBitAge();

Can you provide more details about your XML schema? I have attempted to reproduce you issue with the following

nov30.xsd

I made a smaill change to the XML schema you provided since I do not have the source for common.xsd:

<!--xs:import namespace="glodas.research" schemaLocation="../common.xsd" / -->

<!--  Dashboard Level -->

                        minOccurs="0" maxOccurs="unbounded" />
                <xs:element name="BitsCount" type="BitsCount"
                        minOccurs="0" maxOccurs="unbounded"/>

The resulting list property still uses generics as expected:
