[kepler-dev] Help on "Composite R Data Reader Workflow" examples

[bfu at netspace.net.au]

Hi all,

I am new in Kepler. Just installed it and tried to run the
Composite R Data Reader Workflow examples.

I installed R and set the Path enviroment, and as requested,put
R.dll in Windows/System32 direcotry.

but when I tried to run it , it always throws URI is not absolute
Exception. I have checked the file is in the directory specified in
the DataFileName and R_DATABASE_Reader parameters.

Can anyone give me some hints or solutions on this?

I am using Windowx XP professional. 

Thanks in advance.

Regards
Bin
