JLine only works from IDEA

Question

I have no problem using jline when the code is run within idea. Running with a bat file, the edit characters are not being sent to the terminal.

java -classpath ..\JActor\target\classes;..\JID\target\classes;target\classes;..\slf4j-api-1.7.2.jar;..\slf4j-simple-1.7.2.jar;..\apache-sshd-0.8.0\lib\sshd-core-0.8.0.jar;..\apache-sshd-0.8.0\lib\mina-core-2.0.5.jar;..\apache-sshd-0.8.0\lib\bcprov-jdk15-140.jar;..\jline-2.9.jar;..\joda-time-2.1.jar org.agilewiki.jasocket.sshd.SSHServer %1%

I checked the jline jar file and it contains the fusesource code for jansi and hawtjni.

I'm using sshd to support remote access via PuTTY. I'm confused that running from IDEA would make a difference, though I get the sense that jline expect to be interacting with the local machine. So since I'm running from a windows command window, that might me an issue. Any way to force it? — William La Forge, Jan 19 '13 at 14:16
Added to my code: System.out.println(t.isAnsiSupported()); System.out.println(t.isEchoEnabled()); System.out.println(t.isSupported()); got true/false/true on dos window and false/false/true in idea. environment? like, set a system property for the terminal type? — William La Forge, Jan 19 '13 at 14:25
Copy/paste command from idea console to windows cmd prompt didn't work? — Roman C, Jan 19 '13 at 14:28
then add -Dfile.encoding=UTF-8, or what encoding you have in IDEA? — Roman C, Jan 19 '13 at 14:36
I've tried jline.WindowsTerminal.ansi and jline.WindowsTerminal.directConsole to no avail — William La Forge, Jan 19 '13 at 14:39
using utf-8 in idea, setting that encoding when running java has no effect — William La Forge, Jan 19 '13 at 14:43
yes! Only it looks like jline likes idea somehow. Now, I can force echo and local edits in putty and set the terminal type to none--that works. But that's not quite good enough for a product. :-/ And then I don't really need jline! — William La Forge, Jan 19 '13 at 15:01
do you have the same value for both props, because this props could be used in character streams — Roman C, Jan 19 '13 at 15:06

Turns out, the Terminal used under IDEA and the dos box were different. Forcing the use of the IDEA terminal in all cases didn't work, but this did:

    consoleReader = new ConsoleReader(in, out, new TerminalSupport(true) {});

This same issue occurs when running from within Eclipse, and then later from within Tomcat. The given fix works, although I still don't understand why even though I've been looking through the JLine2 code. – kaliatech May 20 '13 at 17:08
