java - Creating corrupted PDF from bytearray -


i trying generate pdf byte array in java returned through webservice, pdf cannot opened. shows corrupted, have attached code. pls got wrong?

       jsonobject o = new  jsonobject(outjson);        jsonobject jsonob = o.optjsonobject("pdf details");        byte[] pdfbyte=jsonob.optstring("pdf bytearray").tostring().getbytes();        string str1 = new string(pdfbyte);         file somefile = new file("c:/users/acer/desktop/test1.pdf");         fileoutputstream fos = new fileoutputstream(somefile);         byte[] bytedata = str1.getbytes();         byte[] bytedata1 = test.getbytes();         fos.write(pdfbyte);         fos.flush();         fos.close();

following json webservice:

{"pdf details": {                 "id":"121",                  "pdf bytearray":"[b@62a58cd"                  } }

following webservice code outputs bytearray in json:

public response getpdf(  ) {     string flag=null;     file file = new file("c:/users/acer/desktop/report.pdf");     fileinputstream fileinputstream;     byte[] data = null;     byte[] finaldata = null;     bytearrayoutputstream bytearrayoutputstream = null;          fileinputstream = new fileinputstream(file);        data = new byte[(int)file.length()];        finaldata = new byte[(int)file.length()];        bytearrayoutputstream = new bytearrayoutputstream();        fileinputstream.read(data);        bytearrayoutputstream.write(data);        finaldata = bytearrayoutputstream.tobytearray();        fileinputstream.close();        system.out.println(finaldata);     jsonobject jsonobject = new jsonobject();     jsonobject mainjsonobject = new jsonobject();      jsonobject.put("id","121");      jsonobject.put("pdf bytearray",finaldata);     mainjsonobject.put("pdf details",jsonobject);     flag = "" + mainjsonobject;      return response.status(200).entity(flag).build();  }

i got right following chnge in webservice:

public response getpdf(  ) {             string flag=null;             file file = new file("c:/users/acer/desktop/report.pdf");              fileinputstream fileinputstreamreader = new fileinputstream(file);              byte[] bytes = new byte[(int)file.length()];             fileinputstreamreader.read(bytes);             string encodedbase64 = new string(base64.encodebase64(bytes));               jsonobject jsonobject = new jsonobject();              jsonobject mainjsonobject = new jsonobject();               jsonobject.put("id","121");               jsonobject.put("pdf bytearray",encodedbase64);              mainjsonobject.put("pdf details",jsonobject);              flag = "" + mainjsonobject;       return response.status(200).entity(flag).build(); }

my client:

     string encodedbase64=jsonob.optstring("pdf bytearray");       byte[] decodedbytes = base64.decodebase64(encodedbase64);      system.out.println("decbyte   "+decodedbytes);      file somefile = new file("c:/users/acer/desktop/test.pdf");      outputstream fos = new fileoutputstream(somefile);      fos.write(decodedbytes);      fos.flush();      fos.close();
