R help - Jul 2012 - Problem to establish Bloomberg connection / Package RBloomberg / function blpConnect()

Dear All,

 

when I try to call blpConnect() in order to open a connection to the
Bloomberg on my machine, I receive following error message:

 

 

R version 2.15.1 (2012-06-22) 

rJava Version 0.9-3 

RBloomberg Version 0.4-150 

Java environment initialized successfully.

Looking for most recent blpapi3.jar file...

Adding C:\blp\API\APIv3\JavaAPI\v3.4.8.1\lib\blpapi3.jar to Java
classpath

Fehler in .jnew("org/findata/blpwrapper/Connection", java.log.level) :

  java.lang.UnsupportedClassVersionError: Bad version number in .class
file

 

 

 

It looks there is any problem with the installed java version. Has
anyone an idea how to solve that problem?

 

Regards,

 

Alexander Erbse

Alexander,

I agree, this feels like a java version issue. You could start by
telling us what version of Java you're running: open a command prompt
and type java -verision, and reply with the output. I think any
version 1.5 and up should work, but let's see what you have.
