R: RJDBC: Error to connecting Orientdb

Question

如果我尝试在R 3.1.1和RJDBC 0.2-4包中通过OrientDB JDBC连接到OrientDB，我会得到错误。OrientDB启动后，我可以通过OrientStudio执行任何SQL语句。

JDBC驱动程序与OrientDB库位于同一目录。

Error on .jcall(drv@jdrv, "Ljava/sql/Connection;", "connect", as.character(url)[1],  : 
  java.lang.NoClassDefFoundError: com/orientechnologies/orient/core/db/record/ODatabaseRecord

我使用下面的R代码:

library(RJDBC)
drv <- JDBC(driverClass = "com.orientechnologies.orient.jdbc.OrientJdbcDriver", 
            classPath ="./orientdb-community-1.7.4/lib/orientdb-jdbc-1.7.jar" )
conn <- dbConnect(drv, "jdbc:orient:remote://localhost/GratefulDeadConcerts", "admin", "admin")

Answer 1

使用OrientDB JDBC Driver 1.7 ALL包
