i want call add function of hashset delay, without blocking current thread. there easy solution achieve this: utils.sleep(1000, myhashset.add(foo)); //added after 1 second //code here runs without delay ... you can use scheduledthreadpoolexecutor.schedule : scheduledthreadpoolexecutor exec = new scheduledthreadpoolexecutor(1); exec.schedule(new runnable() { public void run() { myhashset.add(foo); } }, 1, timeunit.seconds); it execute code after 1 second on separate thread. careful concurrent modifications of myhashset though. if modifying collection @ same time different thread or trying iterate on may in trouble , need use locks.

i need function generate 3 numbers can use them rgb pattern svg. while simple, need make sure i'm not using same color twice. how do that? generate 1 number @ time simple rand (seed time active) , what? don't want exclude number, maybe whole pattern? i'm kind of lost here. to precise, first calling of function example 218 199 154 , second i'll 47 212 236 2 different colors. suggestions? also think struct int r, int g, int b suitable this? edit: colors should different human eye. sorry not mentioning earlier. you use set store generated colors. first instanciate new set. then, every time generate color, if value present in set. if record exists, skip , retry new colour. if not, can use dont forget cache in set after. may become not performant if need generate big quantity of colour.

i'm working through book thinking in erlang . in "figure 10: example of case" has following example: many(x) -> case x of [] -> none; [ _one ] -> one; [ _one, _two ] -> two; [ _one, _two , _three | _tail ] -> many end. it says : if wondering why line 9 not match against [ _one, _two | _tail ], review list matching rules list tails @ end of previous section. but if match against [ _one, _two | _tail ] still works expected. there error in book or getting wrong ? i think might not error. the semantics of [_one, _two, _three | _tail] is list of 3 elements or more. the semantics of [_one, _two | _tail] is list of 2 elements or more. since third pattern [ _one, _two ] indicates case "a list of 2 elements", using [_one, _two | _tail] little bit redundant. there reason "everything's working expected". if place fourth pattern before third one, gives: ...

i want execute following sql in hibernate: select emp.*, utilspkg.getemployeedisplayname(emp.id) employee emp; so far good... thing - need fetched entity - can update employee. of course pl\sql function not updateable nor part of actual table... how can generate such entity in hibernate - field calculated , not updateable? many thanks! using @formula annotation, explained in hibernate documentation : sometimes, want database computation rather in jvm, might create kind of virtual column. can use sql fragment (aka formula) instead of mapping property column. kind of property read (its value calculated formula fragment).

i'm importing flat file database using data flow task in ssis. file simple: contains 3 comma-separated values per row. whenever run task, however, receive warning flat file component: warning: 0x8020200f: there partial row @ end of file. this warning seems happen regardless of size of file: handful of rows in file, visually validated (with extended characters , whatnot visible) still receive it. moreover, doesn't seem matter whether have blank row @ end of file or end without trailing cr+lf. how can rid of warning can run package warnaserror enabled? (btw, seems else may have had similar problem in there partial row @ end of file , though wasn't of question.) i have found 3 things try if encounter problem. in @ least 2 out of 3 cases, ssis ignoring rows of input file above warning show it. because of that, i not recommend ignoring warning! step 1: verify flat file valid this error appear when have invalid input file. can hard detect if in...

(see code below) main problem: when project2 instantiates jetty, needs pass in full path war file, changes each time. maven adds version number stuff project1's war file. assemblies rescue? i'm able custom assembly work, can't rid of versioning stamp project1. but wind project1-1.4.1-20120530.233546-2.war. it's in more convenient place, name still weird. jetty code in project2: // context webappcontext webapp = new webappcontext(); webapp.setcontextpath("/"); string jettyhome = system.getproperty( "jetty.home", ".." ); string fullwarname = ...; // project1's war file. path changes webapp.setwar( fullwarname ); // server ser...
