i want fetch d:\workdir\upg_81\config\pdmm81dm.pwf of service msqlpdmm81dm string using java , password file cloud -s , -n or -sn option. please suggest better way.

it working fine code,

cfgtest utility parses configuration file , returns specific entry config file.

  process p  = _executeprocess("cfgtest","-m","service.cfg");  bufferedreader br = new bufferedreader( new inputstreamreader( p.getinputstream() ) );   string s = br.readline();  while ( s != null )  {     if ( s.matches( "^\\s*msql.*$" ) )      {        stringtokenizer st = new stringtokenizer( s, " " );        while ( st.hasmoretokens() )        {           if ( st.nexttoken().equals( "-sn" ) )           {              pwf = st.nexttoken();           }        }     }     s = br.readline();  }  br.close();

but change approach , try function returns cfgtest command output single string.

 string cmd = "cfgtest -m service.cfg"; int dstat = shell._execcommand(cmd); string s = null;    s = shell._getcommandoutput();  system.out.println(s);

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
