public class windows {      public static void main(string[] args) throws filenotfoundexception, documentexception {         java.io.file f = new java.io.file("c:/temp/text.pdf");        java.io.fileoutputstream fo = new java.io.fileoutputstream(f);         com.itextpdf.text.document d = new com.itextpdf.text.document(pagesize.a5, 50, 50, 50, 50);         pdfwriter pw = pdfwriter.getinstance(d, fo);        d.open();         boolean b0 = d.newpage();        boolean b1  =  d.addauthor("tamil selvan");         d.addcreator("tamil selvan");        d.addheader("tamil selvan header name", "header content");        d.addkeywords("these keywords document");        d.addsubject("these subjects document");        d.addtitle("the title of document");         d.close();         system.out.println("is documnet opened "+b0);         system.out.println("is documnet working "+b1);      }; }

how can run this?

i believe problem here have provided metadata pdf, no actual body or content pdf.

for example, can try

d.add(new paragraph("some random text"));

and seeing if addresses error facing.

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...
