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]]

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. -John On Mon, Jul 9, 2012 at 4:20 AM, Alexander Erbse <ae at alpha-centauri.com> wrote:
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?
