New question #254612 on Sikuli:
https://answers.launchpad.net/sikuli/+question/254612

i download the latest sikuli 1.1.0 beta4 and setup;
Environment Variables is like this:
JAVA_HOME         C:\Program Files (x86)\Java\jdk1.7.0_05
CLASSPATH           F:\SikuliX\1.1.0\sikulixapi.jar;.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar
JYTHONPATH       C:\jython2.5.3\Lib;C:\jython2.5.3\sikulixapi.jar\Lib

while i Integration sikulix with robotframework (Remote Library), when start Remote Server,I got this error message:

[error] ImagePath: addImagePath: not valid:   /
[error] ImagePath: addImagePath: not valid:   /
Robot Framework remote server at 127.0.0.1:8270 starting.

but,the robotframework can still connect the server and call  this keyword(click_object) remotely sucessfully;
i don't know,why i got this error message?

i start remote server by this command: jython sikuliServer.py

sikuliServer.py source is like this:

import sys
from robotremoteserver import RobotRemoteServer
from org.sikuli.script import *
class SikuliRemoteLibrary:
	def __init__(self):
		self.SS = Screen()
		self.PT = Pattern()
		
	def _wait(self,imgFile,timeOut,similarity):
		self.PT = Pattern(imgFile)
		self.PT = self.PT.similar(float(similarity))
		self.SS.wait(self.PT,float(timeOut))
		
	def click_object(self, imgFile, timeOut, similarity):
		try:
			self._wait(imgFile, timeOut, similarity)
			self.SS.click(imgFile)
		except FindFailed, err:
			raise AssertionError("Cannot click [" + imgFile + "]")
			
if __name__ == '__main__':
	SRL = SikuliRemoteLibrary()
	RobotRemoteServer(SRL, *sys.argv[1:])



and robotremoteserver.py called by above script is like this:
