Thats what I thought, but I can't add a noarg constructor to my subclass as one
doesn't exist in the superclass - TextResponseWriter. All I have done is create
a class that extends TextResponseWriter and implements QueryResponseWriter. The
only method that is actually implemented is ..
public String getContentType(SolrQueryRequest arg0, SolrQueryResponse arg1) {
// TODO Auto-generated method stub
return CONTENT_TYPE_TEXT_UTF8;
}
ie the class at the moment, does nothing, but it shouldn't cause an error.
I did realise that I was unknowingly compiling my class using a 1.4 jdk using
maven, but have since recitfied that and the error is still there.
