I am having a puzzling problem with bloomberg connection. When i run from R
prompt some code that has
....
library(Rbbg)
conn <- blpConnect(throw.ticker.errors = FALSE)
print("connected")
...
I establish connection every time and then proceed to get data when i run this
code from R prompt. However, when i run this from a batch script, i get the
following error output from Rbbg:
=====================
R version 2.15.2 (2012-10-26)
rJava Version 0.9-4

Adding C:\blp\API\APIv3\JavaAPI\v3.5.1.1\lib\blpapi3.jar to Java classpath
<simpleError in ls(envir = envir, all.names = private): invalid 'envir'
argument>
=======================
I looked in Rbbg and Bloomberg log files and they have the following:

============================
None of these error messages gives me a clue of what could be wrong. The only
vague thought i have is that something about Java or rJava might not be
initializing correctly. I must admit i am not used to running things on
Windows, so maybe i am missing something simple. Just in case i did something
stupid I simply have the following in my batch file
R CMD BATCH --no-restore --no-save "C:/Users/.../tmp.R" "C:/Users/.../tmp.out"
and tmp.R has a call to function that connects to Bloomberg. Batch is invoked
by scheduler
I am running
R version 2.15.2 (2012-10-26)
rJava Version 0.9-4
Rbbg Version 0.4-155
64 bit Win 7 Ultimate
Would greatly appreciate any hints
Andre
