[R] Problem to establish Bloomberg connection / Package RBloomberg / function blpConnect()

[John Laing]

OK. Are you running 32 bit or 64 bit R? And 32 bit or 64 bit Java?

This can help shed light on the settings for the JVM being accessed by R:
require(rJava)
.jinit()
jvm <- .jnew("java.lang.System")
jvm.props <- jvm$getProperties()$toString()
jvm.props <- strsplit(gsub("\\{(.*)}", "\\1", jvm.props), ", ")[[1]]
