java - How to convert a String FIX message to FIX FIX50SP2 format using QuickFixJ -


need quick help. newbie in quickfixj. have fix message in txt file. need convert fix50sp2 format. enclosing code snippet.

string fixmsg = "1128=99=25535=x49=cme34=47134052=20100318-03:21:11.36475=20120904268=2279=122=848=336683=607400107=esu2269=1270=140575271=152273=121014000336=2346=521023=1279=122=848=336683=607401107=esu2269=1270=140600271=206273=121014000336=2346=681023=210=159";  system.out.println("fixmsg string:"+fixmsg); message fixmessage = new message(); datadictionary dd = new datadictionary("fix50sp2.xml"); fixmessage.fromstring(fixmsg, dd, false); system.out.println("fixmessage output:" + fixmessage.tostring()); // print message after parsing msgtype msgtype = new msgtype(); system.out.println(fixmessage.getfield(msgtype));

here output:

fixmsg string:1128=99=15835=x49=cme34=47164052=2012090312102051175=20120904268=1279=122=848=336683=607745107=esu2269=1270=140575271=123273=121020000336=2346=501023=110=205 fixmessage output:9=6135=x34=47164049=cme52=2012090312102051175=20120904268=110=117 quickfix.fieldnotfound: field [35] not found in message.     @ quickfix.fieldmap.getfield(fieldmap.java:216)     @ quickfix.fieldmap.getfieldinternal(fieldmap.java:353)     @ quickfix.fieldmap.getfield(fieldmap.java:349)     @ mainapp.main(mainapp.java:52)

i want extract msgtype field (field 35). please tell me wrong? thing have observed after parsing fix50sp2 format, convert fix message missing many data element (for details see output)

thanks

like others mentioned msgtype header field , using following

string msgtype = null; if(fixmessage.getheader().issetfield(msgtype.field)) {     msgtype = fixmessage.getheader().getstring(msgtype.field); } system.out.println("msgtype " + msgtype);`

the reason missing many data element after parsing is, message have custom tags(like tag 2346), not defined in data dictionary(fixsp02.xml). hence parsing of tags failed , missing in output.

to fix this, data dictionary party sending message , use parse message

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
