java - WinZip is unable to open zipped file prepared using Apache commons compress ApI -

-

i have scenario zip files , folders (with sub-folders). able achieve using apache commons compress library, this post. have application uses java.util.zip library unzip file. utility not able read apache commons compress zipped folder, first zipentry null.

however when zipped file prepared using winzip, utility has no problem in unzipping it.

i tried unzip compression zip file using winzip, gives error - unable open local header "filename". idea how add local header files? checked source code ziparchiveoutputstream, writetolocalheaderfile.

any pointers issue? unzip code below: 

{ file destdir = new file(destdirectory); zipinputstream zipin = new zipinputstream(new fileinputstream(zipfilepath)); zipentry entry = zipin.getnextentry();  // iterates on entries in zip file while (entry != null) {     string filepath = destdirectory + file.separator + entry.getname();     if (!entry.isdirectory()) {         // if entry file, extracts         extractfile(zipin, filepath, currentsize, totalsize);     } else {         // if entry directory, make directory         file dir = new file(filepath);         dir.mkdir();     }     zipin.closeentry();     entry = zipin.getnextentry(); } zipin.close(); }

however able see there entries available in zip file through other ways, unfortunately cannot include new code in utility. code snippet:

zipfile zipfile =  new zipfile(new file(zipfilepath)); enumeration entries = zipfile.entries();    while(entries.hasmoreelements()) {        zipentry ze = (zipentry) entries.nextelement();        system.out.println(ze.getname());        if(!ze.isdirectory())            system.out.println("is not directory");    }

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
