[ImageJ-devel] jython scripting, No compatible service: io.scif.SCIFIOService

[Harri Jäälinoja]

Hi,

I started to learn about ImgLib2 for the purpose of creating scripts I 
can run headlessly. I would like to use jython since I already used that 
with ImageJ1. First I downloaded a recent Fiji version. My idea was that 
this would be the easiest way to get the dependencies (scifio, imglib2 
etc.) right.

mkdir fiji-20140219
cd fiji-20140219/
wget 
http://jenkins.imagej.net/job/Stable-Fiji/lastSuccessfulBuild/artifact/fiji-linux64.tar.gz
tar xf fiji-linux64.tar.gz


Then I just put all the jar files in the Fiji distribution in one long 
variable and gave that as the classpath for Jython
CP=`find /home/hajaalin/Software/fiji-20140219/Fiji.app/jars -name 
'*.jar' |sed ':a;N;$!ba;s/\n/:/g'`

Here's my test script:

----- imglib0.py ------
import sys

#from io.scif.config import SCIFIOConfig
from io.scif.config import *
from io.scif.img import ImgIOException,ImgOpener

from java.io import File

from net.imglib2.img import Img
from net.imglib2.img.display.imagej import ImageJFunctions
from net.imglib2.type import NativeType
from net.imglib2.type.numeric import RealType

filename = sys.argv[1]

io = ImgOpener()
config = SCIFIOConfig()
config.imgOpenerSetImgModes( SCIFIOConfig.ImgMode.CELL )
img = io.openImg(filename)

ImageJFunctions.show( img )
---------------------------


When I run it, I get an error I've seen on the list before:

No compatible service: io.scif.SCIFIOService


If I try to run the script via Fiji, I don't get even that far:

hajaalin at biotek973:~/Software/fiji-20140219/Fiji.app$ ./ImageJ-linux64 
macros/imglib0.py /home/hajaalin/Data/Misha/composite1.ome.tif
Traceback (most recent call last):
   File "macros/imglib0.py", line 4, in <module>
     from io.scif.config import *
ImportError: No module named io


So now my questions are:
1. Is there a better way to get all the dependency jars?
2. Is there something wrong with my general setup (jython + script + 
required jars)?


Thanks, best regards,
Harri
