To set the name of an XML element I use annotations like this: @XmlElement(name

  • 0

To set the name of an XML element I use annotations like this:

@XmlElement(name = "customer_id")
public String getId(){}

I have to communicate with two different webservices. One expacts an id element named customer_id but the other expacts the id element to be named id. I solved the problem by creating a second Customer class with the same attributes. The only different is that it uses the following annotation

@XmlElement(name = "id")
public String getId(){}

and it has a copy constructor which copies all attributes from Customer1 to Customer2. When I am communicating with the first webservice I send a Customer1 object and the other webservice gets a Customer2 object.

Is there any possibility to use only one Customer object, but rename the id attribute to whatever the webservice expects?
