After install iepy in a virtualenv environment,I get this error:

(iepy)lcq@27:~$ iepy -h
Traceback (most recent call last):

It looks like java can't be run.But I can run it from shell.

(iepy)lcq@27:~$ java -version
Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar 
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

This is my java profile

export JAVA_HOME=/home/lcq/jdk1.8.0_60/
export JAVAHOME=$JAVA_HOME
export JRE_HOME=${JAVA_HOME}/jre 
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib 
export PATH=${JAVA_HOME}/bin:$PATH

I use ubuntu 15.04 and python 3.4.3.Could you help me ?

I got it. JAVAHOME must be java executiable itself.Not the folder.And Picked up JAVA_TOOL_OPTIONS is a extra problem,need to be remove.I use ugly method unset JAVA_TOOL_OPTIONS.
