11 years ago Okay I've been looking into this a bit more and here is what I've found out. In process_runner.rb under JRuby spawn apparently does not support redirecting stdout which is why I'm getting the response printed to the console. This is the java error that is thrown:
ERROR [stderr] (http-/127.0.0.1:8080-5) file:/c:/torquebox/jruby/lib/jruby.jar!/jruby/kernel19/process.rb:4 warning: unsupported spawn option: out
To avoid this you can use IO.popen as you can capture stdout using this under JRuby.
However, this has another problem. Under JRuby when using IO.popen I can't seem to get the environment setup properly.
If I do:
environment = {}
supplemental_path = "C:/Program Files (x86)/ImageMagick-6.8.0-Q16"
environment['PATH'] = [ENV['PATH'],*supplemental_path].join(File::PATH_SEPARATOR)
IO.popen([environment, "convert"]) { |io|
puts io.read
}Then you'll get: org.jruby.exceptions.RaiseException: (IOError) Cannot run program "convert" (in directory "C:\my-ruby-project"): CreateProcess error=2, The system cannot find the file specified
Under mri ruby it will run the convert command fine and just print the syntax for the convert command.
I'm currently also having problems even when you add imagemagick to the path in windows. For some reason despite the fact that imagemagick is on the path and running convert in a cmd prompt is okay, jruby wants to execute the other convert on windows which is for converting partitions to ntfs. MRI works fine.
The only way I can see around this is appending the full path to the front of the command which is obviously a less then ideal solution.

I originally encountered the error when using Paperclip but it seems related to Cocaine.
with the last call in the backtrace being: cocaine (0.4.2) lib/cocaine/command_line.rb:80:in `run'
If I attempt to try and execute a simple test:
in one of the instances of the JRuby interpreter running inside the JBoss AS it throws the following:
I can only seem to get a Java stacktrace here. However, in the console that JBoss is running in the following is printed:
16:00:14,351 INFO [stdout] (Thread-130) hello worldI noticed that had been some previous issues with JRuby so I tried using
Cocaine::CommandLine.runner = Cocaine::CommandLine::BackticksRunner.newbut this results in:Errno::EINVAL (Invalid argument - =ExitCode)Using JRuby version:
