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

[Ignacio Ramos Alvarez]

Hello all.
Just to update my problem, I have tried RBloomberg on a PC at home and
works perfectly. I am Java ignorant but I suspect it probably has
something to do with the rJava package or the Java in my machine at
work, we have to run a specific older version of java (2005) for
several reasons.
Ana, I don't know if you've been looking into this, in any case thanks
for the package. Are you planning to use the C API interface in future
versions?.
I guess I'll keep on downloading Bloomberg data with Excel or VB.
Have a great day.

Nacho.
