Basic questions about uploading files in JSF -

-

i have never used uploading feature in jsf, have to. have couple of questions , "for dummies" series questions. so:

1) logged in users' pictures db or filesystem of server?

2) if server relative or fixed path or root url db/properties , relative part db too?

3) if db, how performance when using jpa2 + mysql? cons otherwise?

4) if using server, secure add new context images server.xml , use images address www.examble.com/imagesfolder/images.jpg? how avoid situation can see pictures?

5) best way handle uploading? using primefaces, purpose or else?

6) tutorial or examples how pro :)?

7) how avoid situation there might files same name? hashing names or?

8) if (really big if) decide share application 2 physical servers, problems paths pictures?

9) in case, have pictures, common , pictures "owned logged in users. how implement , why if know using primefaces, jpa2 , mysql , have unlimited space in server?

10) nice , hot summer everyone!!

most of questions file once have uploaded, that's design matter , depend on software architect, team leader or in last case on yourself. there 2 answers server filesystem/database file saving:

to handle problems described in "7)" , "8)", should use file server , content management systems. add more benefits file storage, searching, indexing , more. here examples:

to implement file uploading using jsf (note: pro, follow pros ways):

give try these samples. if have problem in coding better ask new question.

edit: forgot of number 4, reminder. add new context, stated, , create filter catch requests new context , redirect default url.

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
