how to access IJCoClientService in NDS

hi all,

I am trying to compile an JCO example in NDS, its giving error for the interface com.sapportals.portal.prt.service.jco.IJCOClientService.

It would be helpful if any one tell me what ‘.jar’ file I need to add to the project classpath so as to remove this error and let me know where i can find out that.

thanks in advance
