这是我之前一篇关于在 Mac 上使用 R 和 JAVA 的后续文章。我的应用程序依赖于 R 来运行。我已经安装了 Java，Java 版本“1.6.0_37”。我已经安装了“R”，R 版本 2.15.1。现在我需要包含在rJava中的 JRI 。
在 R 内部，我运行了以下命令
install.packages('rJava',,' http: //www.rforge.net/ ')
这是输出：
install.packages('rJava',,'http://www.rforge.net/')
trying URL 'http://www.rforge.net/bin/macosx/leopard/contrib/2.15/rJava_0.9-4.tgz'

我从这里去哪里？
启动tomcat时出现以下错误：

Please make sure that the JRI native library is in a directory listed in java.library.path.

更新 2/15/13 尝试设置环境变量后...
我自己的路：

仍然收到上面的错误。
