String declaration = "private java.util.List<String> x = new java.util.ArrayList<java.lang.String>();";   CtField f = CtField.make(declaration, fieldClass);   fieldClass.addField(f);   fieldClass.writeFile(); Can someone tell me if this is possible? Thank you for any help -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/539222#539222] Start a new discussion in Javassist at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
