Please see

https://jsr311.dev.java.net/servlets/ReadMsg?listName=users&msgNo=189

Now, what you can do to get the default value in a method if no value is set, 
is to override a Message.QUERY_STRING in a request filter, ex :

@Context UriInfo ui;

void Response handleRequest(ClassresourceInfo cri, Message m) {
      StringBuilder sb = new StringBuilder();
      for (Map.Entry<String, List<String>> entry : 
ui.getQueryParameters().entrySet()) {
           String queryName = entry.getKey();
           
           List<String> queryValues = entry.getValue();
           for (String value : queryValues) {
                sb.append(queryName + "=");
                sb.append(value.length() == 0 ? "-1" : value);
           }           
       }
       message.put(Message.QUERY_STRING, sb.toString());
}


alternatively create a bean class :

public class QueryBean {

private Strring id = "-1";

public void setId(String idValue) {
    if (!"".equals(idValue)) {
        id = idValue;
    }
}


and use QueryParam("") QueryBean
}
