I need help. I'm trying to connect with an Oracle DBMS and MySQL DBMS, I'm using RJDBC package. My code is the next: library('rJava') library('DBI') library('RJDBC') //Mysql drv <- JDBC("com.mysql.jdbc.Driver","C:\\Temporal\\mysql-connector-java-3.0.9-stable-bin.jar","'") conn <- dbConnect(drv, "jdbc:mysql://localhost:3306/bd", "user", "password") //Oracle drv <- JDBC("oracle.jdbc.driver.OracleDriver","C:\\Temporal\\classes12.jar","'") conn <- dbConnect(drv,"jdbc:oracle:thin:@192.168.1.70:1521:SDS22","user","password") R always returns for oracle "Error en .local(drv, ...) : Unable to connect JDBC to jdbc:oracle:thin:@192.168.1.70:1521:SDS22" and for mysql "Error en .local(drv, ...) : Unable to connect JDBC to jdbc:mysql://localhost:3306/bd" And the function summary(drv) returns: JDBCDriver name = JDBC driver.version = 0.1-1 DBI.version = 0.1-1 client.version = NA max.connections = NA R version 2.4.1 (2006-12-18) i386-pc-mingw32 locale: LC_COLLATE=Spanish_Spain.1252;LC_CTYPE=Spanish_Spain.1252;LC_MONETARY=Spanish_Spain.1252;LC_NUMERIC=C;LC_TIME=Spanish_Spain.1252 attached base packages: [1] "stats" "graphics" "grDevices" "utils" "datasets" "methods" [7] "base" other attached packages: RJDBC DBI rJava "0.1-2" "0.1-12" "0.4-14" Can you help me, please?
