ZK - Open Source Ajax Java Framework

I have just started learning ZK . I have installed ZK(latest version) on eclipse gailieo 3.5 with tomcat 5.5 on ubuntu 8.04. When I try to
run the SIMILE Timeplot demo from zk editor in eclipse galileo, it gives the error
"Failed to load data xml from /root/workspace/helloa3/workspace/immigration.txt
Not Found"
"Failed to load data xml from /root/workspace/helloa3/workspace/us_history.xml
Not Found"
#immigration.txt and us_history.xml are files required to plot the graph I have downloaded them and put them in helloa3 folder which is my project folder.What should I do to cite correct path?

For a convenience way, you can put them with your zul file at the same level, just like zkdemo did, more details, please check the zkdemo example.
