r - 从 R 连接到 Bloomberg

Question

我收到错误：

Error in .jnew("org/findata/blpwrapper/Connection", java.log.level) : 
  org.findata.blpwrapper.WrapperException: Session not started because: Failed to connect server: localhost/127.0.0.1:8194

当我在 R 2.15.0 上运行命令 blpConnect()

这是整个输出：

> blpConnect()
R version 2.15.0 (2012-03-30) 
rJava Version 0.9-3 
Rbbg Version 0.4-153 
Java environment initialized successfully.
Looking for most recent blpapi3.jar file...
Adding C:\blp\API\blpapi3.jar to Java classpath
Error in .jnew("org/findata/blpwrapper/Connection", java.log.level) : 
  org.findata.blpwrapper.WrapperException: Session not started because: Failed to connect server: localhost/127.0.0.1:8194

我不知道那是什么意思？

提前致谢。
