Hi. I nearly have Rserve working.... I have the dialog box which says.. Rserve: Ok, read to answer queries. Having read all i can find, I followed the guidance given on http://rosuda.org/Rserve/example.shtml I tried to follow the first example but I am getting an error descirbed below. My IDE looks like this: http://www.nabble.com/file/p10705244/ide.jpg However, when I try and compile my java file I get the following error: Cannot access Rconnection bad class file: C:\org\rosuda\JRclient\Rconnection.class class file contains wrong class: org.rosuda.JRclient.Rconnection Please remove or make sure it appears in the correct subdirectory of the classpath. Rconnection c = new Rconnection(); ^ I am not quite sure I am doing wrong here... Could someone look at my IDE tree hierarchy and give me some guidance?
