@xmlaccessortype(xmlaccesstype.field) @xmltype(name = "reservationsummarydto", proporder = {     "hotelcode",     "summarymonth" }) public class reservationsummarydto {      protected string hotelcode;     @xmlelement(nillable = true)     protected list<summarymonthdto> summarymonth; } 
@xmlaccessortype(xmlaccesstype.field) @xmltype(name = "summarymonthdto", proporder = {     "month",     "summarytype" }) public class summarymonthdto {      protected string month;     @xmlelement(nillable = false)     protected list<summarytypedto> summarytype; } 
@xmlaccessortype(xmlaccesstype.field) @xmltype(name = "summarytypedto", proporder = {     "date",     "displaysequence",     "total",     "typecode" }) public class summarytypedto {      @xmlelement(nillable = true)     protected list<summarydatedto> date;     protected integer displaysequence;     protected double total;     protected string typecode;

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
