java - BPM - byte array - not expected -

-

i've got problem when trying compress .xls file zip file in bpm platform (bea aqualogic bpm - studio). code far:

try { fileoutputstream fos = fileoutputstream(arg1 : "/home/and/reportes/ziptest.zip"); zipoutputstream zos = zipoutputstream(arg1 : fos);  logmessage("mas - zippeo en: " + url);  java.io.file file = java.file(arg1 : url); fileinputstream fis = fileinputstream(arg1 : file); zipentry entry = zipentry(arg1 : url); zos.putnextentry(arg1 : entry);  int buff = 1024; byte[] buffer = new byte[buff];  int length; //int buffer = 1024;  while((length = fis.read(buffer,0,1024)) >= 0){     zos.write(arg1 : buffer, arg2 : 0, arg3 : length); } } catch (filenotfoundexception e) { logmessage("mas - fnfe: " + e.stacktrace); } catch (ioexception e) { logmessage("mas - ioe: " + e.stacktrace); }

what i'm getting, compiling error:

''byte'' not expected

and simple quotation marks btw (as in ' ')

any idea or how solve it?

thanks in advance

edit: also, i'm getting error:

argument not valid 'arg1'. type 'byte array' not compatible 'binary'

in "fis.read" and"zos.write"

javascript - Create websocket without connecting -

-
is there way create websocket without connecting right away? far think var ws = new websocket("ws://ws.my.url.com"); creates , connects right away. i'd create socket, define callbacks, , connect once user clicks connect button. thanks no. creating websocket means you've created connection server (or started process of connecting). there no such thing creating websocket isn't connecting yet. you create object store configuration parameters , tell object connect when wanted to, though i'm not sure why that's better creating actual websocket when connect made. or create function setup work , call function later when user clicks connect button.
