Getting the JAXB exception like "Two classes have the same XML type name...",
Here is the exception details:
Exception in thread "main"

"city". Use @XmlType.name and @XmlType.namespace to assign different names
to them. this problem is related to the following location: at
com.model.City at public com.model.City com.model.Address.getCurrentCity()
at com.model.Address this problem is related to the following location: at

I took the example like:
package com.model; ---->this package contains 'Address' class and 'City'
class
public class Address {
private String areaName;
private City currentCity;
private com.common.City previousCity;
}
package com.model;
public class City {
private String cityName;
}
Another city class in "com.common" package.
package com.common;
public class City {
private String pinCode;
}
We need to create XSDs and needs to do the Marshalling and unmarshalling
with the existing code in our project(like as above example code), code
does not have any annotations like "@XmlRootElement/@XmlType" and we can
not able to change the source code.
I would like to know is there any solution to fix the above issue or any
other ways to create XSDs and marshaling/unmarshalling(like MOXy..etc)?
It would be great if i can get the solution from any one....May thanks in
advance.
Thanks,
Satya.
