java - Communication between different Jar's/Classloaders -

-

i've got following problem solve:

there 2 jar files. these jar's start independently each other.

now, let's first jar a.jar calculates or computes , has commit results b.jar.

i tried communicate via central singleton (enum singleton , singleton uses own classloader mentioned here: singleton class several different classloaders).

but didn't seem work me. when start 2 jar's hashcode of instances different.

can tell me i'm doing wrong? or other ideas how solve problem?

there 2 jar files. these jar's start independently each other.

so they're separate processes. won't share instances of classes, variables etc. need form of inter-process communication communicate between them.

that mean form of network protocol (e.g. tcp/udp sockets, http etc.). simple reading/writing shared file (that's not particularly nice, straightforward simple cases)

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution: ...

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
