[R-SIG-Finance] RBloomberg (java version) error

Fri Jul 23 12:50:11 CEST 2010

I would hope to someday support the C interface but it's not going to
happen any time soon unfortunately.

Would it be possible to set up a virtual machine running a newer
version of Java perhaps?

According to rJava, Java 1.4 or greater is required. What Java version
do you have at work? I'm not sure what the Bloomberg requirement is.
