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

[Alexander Erbse]

John,

the problem is now resolved. I changed the "PATH" environment variable. I replaced the path leading to the old java installation by the new one and now it works.

Thanks for your help.

Regards,
Alex

Hi John,

I did some further checks and noticed that the java version, which is indicated by the settings (I used the code you sent) is version 1.5.0_12, although I installed version 1.7.0_05 shortly. The paths as shown by parameter "java.endorsed.dirs" are wrong. They are pointing to an older version of java on my machine. Do you know how I can rJava have referring to the correct directories, where I have the newer version of java?. (C:\Program Files\Java\jre7\lib..)

I guess that would likely solve the problem.

Thanks,
Alex

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]]
