input stream was truncated while reading a word

[jurivrljicak]

Hello, from

SaneSession.java  

private void initSane() throws IOException {
    // RPC code
    outputStream.write(SaneRpcCode.SANE_NET_INIT);

    // version number
    outputStream.write(SaneWord.forSaneVersion(1, 0, 3));

    // username
    outputStream.write(System.getProperty("user.name"));
    outputStream.flush();

    **inputStream.readWord();**
    inputStream.readWord();
  }

I am getting 'input stream was truncated while reading a word' in the highlighted line.
I don't know why this happens, any idea?

Very often I have to plug/unplug the device for it to establish a communication but this time I can't pass through this error. Got stuck in there.

Using Ubuntu 16.04 LTS and the latest from jfreesane (1.0)

thanks

Can you send me the code you're using to call jfreesane?

It's where I am trying to establish the connection.

			this.inetAddress = InetAddress.getByName(this.host);
			saneSession = SaneSession.withRemoteSane(inetAddress, port);

using Oracle OpenJDK 17.0.2

could this be a hardware issue? I was tending to think that

[sjamesr]

Do you have a SANE daemon listening on the appropriate port? You can try the regular sane frontend, scanimage, to obtain an image: scanimage -d net:localhost:<deviceName> If that works, then something is up with jfreesane.

hmmm, the port is the default one

yes, scanimage -d kds_i900:i900 > output.pnm does work

That's not using the sane daemon though, that command is talking to the scanner directly. Try something like: scanimage -d net:localhost:kds_i900:i900

oh, sorry, then I get

$ scanimage -d net:localhost:kds_i900:i900
scanimage: open of device net:localhost:kds_i900:i900 failed: Error during device I/O

[sjamesr]

You'll have to set up the sane daemon. Something like https://help.ubuntu.com/community/SaneDaemonTutorial

yes I don't know, I restarted the sane daemon and started working again, looks that process dies at anytime and I am unaware. Sorry for this and thx again

I've had this happen to me as well

my code:
InetAddress address = InetAddress.getLocalHost();
SaneSession saneSession = SaneSession.withRemoteSane(address);
List devices = saneSession.listDevices();

[tita-tovenaar]

Good evening all,

When trying to run the following code in Eclipse IDE:

package test;

import java.io.IOException;
import java.net.InetAddress;
import java.util.List;

import au.com.southsky.jfreesane.SaneDevice;
import au.com.southsky.jfreesane.SaneException;
import au.com.southsky.jfreesane.SaneSession;

public class SaneTest {

public static void main(String[] args) throws IOException, SaneException {
InetAddress address = InetAddress.getByName("pi-scan");
System.out.println("Address: " + address);

  SaneSession session = SaneSession.withRemoteSane(address);
  System.out.println("Session: " + session);
  
  List<SaneDevice> devices;
  devices = session.listDevices();

}

}

I get the following error output:

Address: pi-scan/10.0.0.29
Session: au.com.southsky.jfreesane.SaneSession@17f052a3
Exception in thread "main" java.io.IOException: input stream was truncated while reading a word

at au.com.southsky.jfreesane.SaneInputStream.readDeviceList(SaneInputStream.java:47)
at au.com.southsky.jfreesane.SaneSession.listDevices(SaneSession.java:220)

What happened? Can you help me? Thanks in advance.
