@Ali, Have you added the directory to the classpath?

Hey @Maverick, thank for responding. yes I've added the directory

.jaddClassPath("C:\Users\Ali\Desktop\R")
cassdrv <- JDBC("org.apache.cassandra.cql.jdbc.CassandraDriver",
"C:\Users\Ali\Desktop\R\cassandra-jdbc-1.2.5.jar")

Cassandra drivers seem to have dependencies that are not included with the driver. Make sure you get those as well and that you add all the JAR files to the class path.
