connection of java and R with Rserve

Question

I have java application for analysis for which need to have R installed. I have R also installed in my system and I installed Rserve library. But when I am trying to implement command Rserve() in my R console, following error is coming:

SOCK_ERROR: bind error #98(address already in use)

I have installed all the prerequisite, along with Rserve, needed for my java application and I think these are working fine except Rserve. Can anybody help me out from this predicament?

The tool name is cytoscape along with that I want to run DvD application for which it is throwing error. And operating system is Linux (CentOS).

Thanks, Mandar

Answer 1

it means that you have a running server on the same host and on the same port. It could be caused by a previous execution who never shut down the server. You could try connecting to the server and shut it down, if you have a client, or verify if there's a server running. Since you are on CentOS you could understnd with a :

ps faux | grep Rserve

If you see a row like

root     23762  0.0  0.7 211304 28632 ?        Ss   14:11   0:00 /usr/lib64/R/bin/Rserve

then you know you have it. You could kill the server and re-run your tool.
