How do you generate a schema from JAXB Objects that reference enums in a different package?
Below is an example:
Enum Class
package com.example.one
public enum EnumExample {
VALUE_ONE
VALUE_TWO
}
JAXB Class
package com.example.two
public class Example {
private EnumExample enumExample;
@XMLElement(name="enumExample", required=true)
public EnumExample getEnumExample() {
return enumExample
}
public void setEnumExample() {
this.enumExample = enumExample;
}
}
package-info.java
@javax.xml.bind.annotation.XmlSchema(namespace = "http://example.com", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.example.two;
Ant Target
<path id="glassfish.schemagen.classpath">
<pathelement location="/apps/glassfish/lib/webservices-tools.jar" />
</path>
<taskdef name="schemagen" classname="com.sun.tools.jxc.SchemaGenTask">
<classpath refid="glassfish.schemagen.classpath" />
</taskdef>
<schemagen srcdir="${src.dir}/com/example/two" destdir="xsd">
<schema namespace="http://exmaple.com" file="example.xsd" />
</schemagen>
When I run the above example I get the following:
[schemagen] anomalous package-info.java path: package-info.java [schemagen] Generating schema from 7 source files [schemagen] Problem encountered during annotation processing; [schemagen] see stacktrace below for more information.

I know it's the enum's causing the error because if I switch to a String it goes away. How can I generate a schema with the above example where the enums are either in the same namespace or a different name space?
