Essentially, I have several servers at my disposal. My data files are almost 1 GB per file and I am trying out several machine learning algorithms from weka package. I have two jar files weka.jar and weka-src.jar and one more libsvm.jar.

I wanted to use these jar files on several linux machines and was able to run it on one of the severs by using the java sdk version. But the other servers ( one of them a cluster of 8 computer are having their own java version called gij and it is not letting me set my path to my own compiler or taking up my class path. I am not able to run with the gij java either. so, is it a security issue ( I dont have rights to set path ?) .. How to run my programs using the jar files.... ( either with my java compiler or gij )? appreciate your response. thanks..

successful path setting in one linux server: since it gives version number of the new java home

JAVA_HOME=/home/guest/SDK/jdk
export JAVA_HOME
export PATH=$JAVA_HOME/bin:$PATH
java -version
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode)

WEKA_HOME=/home/guest/Weka-3-5
export WEKA_HOME

export CLASSPATH=$WEKA_HOME/weka.jar:$CLASSPATH
export CLASSPATH=$WEKA_HOME/weka-src.jar:$CLASSPATH

unsuccessful : when done on another cluster and another linux.
it insists on using gij and is not letting me use java command.

all the above commands have no use. The verison shows the gij info.

gij --mx = 1024 -jar /home/saras/weka-3-5/weka.jar /home/saras/weka-3-5/weka-src.jar weka.classifiers.functions.SMO -t /home/saras/wind11-cls4-FullSet.arff

and I get a noclass found.

Hello,

You are allowed to set your path under any Linux distribution using following syntax:
You need to add export command to .bashrc or .bash_profile
