How to copy content of generic object for specific object - object

Question

I need a support in this code, I have a method that I get generic object and a String, so according to the String I get I want to copy the contents of the generic object to
specific object, one observation that Object TypeA don't have same fields that TypeB. for example:
Thanks in advance
#POST
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
#Authorize("Receiving")
#Path("/Print")
public Response LabelPrint(#Context HttpServletRequest request,
final Object generic
,#QueryParam("Type") final String Type) {
if ( Typex.compareTo("X")) {
TypeA typeA = generic;
...
} else {
TypeB typeB = generic;
...
}
return buildResponse(OK);
}
I tried that away, but unsuccessfully
if (labelType.compareTo("X")) {
TypeA x = new TypeA();
BeanUtils.copyProperties(x, generic);
}
else {
TypeA y = new TypeA();
BeanUtils.copyProperties(y, generic);
}

I managed to do it that away, receiving how String
public Response LabelPrint(#Context HttpServletRequest request,
final String objetcForImpression
,#QueryParam("Type") final String Type) {
if ( Typex.compareTo("X")) {
try {
ObjectMapper objetcForImpression = new ObjectMapper();
TypeA typeA = objetcForImpression.readValue(objetcForImpression, TypeA.class);
} catch (JsonParseException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
...
} else {
try {
ObjectMapper objetcForImpression = new ObjectMapper();
TypeB typeB = objetcForImpression.readValue(objetcForImpression, TypeA.class);
} catch (JsonParseException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return buildResponse(OK);
}
