-

i working on application(java applet) interacts scanner. understand need twain library or wia library make work in windows. not sure differences of two? trying use library:

http://thorntonzone.com/manuals/compression/fax,%20ibm%20mmr/mmsc/mmsc/uk/co/mmscomputing/device/twain/index.html

jar file link broken got here. http://rsbweb.nih.gov/ij/plugins/twain-scan.html

and dlls here: http://sourceforge.net/projects/twain-dsm/?source=dlp

but, not detect source. here error log:

http://pastebin.com/cb9gl0ip

i on 64bit machine. had success?

twain specification long follow , haven't found resources on wia implementation.

any help/pointers/resources appreciated.

use same bit mode

for twain device control in java, all components need in same mode. i.e. jre, twain dsm (source manager), , twain driver (scanner driver) all need 32-bit or 64-bit. no mixing.

the default installation of 64-bit windows contains 32-bit mode of twain dsm. , you've downloaded 64-bit dsm. it's scanner's driver 32-bit , why cannot found.

you have 2 options:

keep 64-bit.

  • use 64-bit twaindsm.dll.
  • make sure jre/jdk 64-bit.
  • make sure scanner has 64-bit driver.

my scanner doesn't have 64-bit driver available, tested 64-bit configuration using 64-bit "virtual scanner" , worked.

keep 32-bit (recommended)

  • use 32-bit twaindsm.dll.
  • make sure jre/jdk 32-bit.
  • use scanner's 32-bit driver (probably default).

you can download 32 , 64 bit twain virtual scanners here.

note: mention jdk because if you're running code ide may pointing different jre to system default. true story, happened me.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
