我试图在Mac OS X系统中使用RJDBC通过R控制台访问一个mysql数据库，但是在＆＃34; ＆GT;图书馆（＆＃39; RJDBC＆＃39;）＆＃34;。立即显示一条消息，指示必须安装旧的Java 6 mac os版本。
我已经安装了打包包＃34; ＆GT; install.packages（＆＃39; RJDBC＆＃39;，依赖= TRUE）＆＃34;
我的系统有： OSX = Mac Os X（约塞米蒂） R版本3.1.2（2014-10-31） 安装java 7并在我的./bash_profile文件中设置JAVA_HOME env变量。
echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home
如果有用的话
R CMD javareconf

我做错了什么？我甚至查看了一篇旧帖子how to get rJava 0.9-3 to work on OS X 10.7.4 with Oracle Java 1.7?和http://mailman.rz.uni-augsburg.de/pipermail/stats-rosuda-devel/，但我还没有能够让它发挥作用，有人可以帮助我吗？
