RBloomberg (java version) error

Hi Ana, thanks for your reply.

1)

cn <- blpConnect()

R version 2.11.1 (2010-05-31)
rJava Version 0.8-4
RBloomberg Version 0.4-142
Java environment initialized successfully.
Looking for most recent blpapi3.jar file...
Error in blpConnect.Java("warning", NULL, TRUE, NULL) :
? Can't find C:\blp\API\APIv3\JavaAPI please confirm you have Bloomberg Version 3 Java API installed. If it's in a different location, please report this to RBloomberg package maintainer.

cn <- blpConnect(blpapi.jar.file="c:\\Program Files\\blp\\API\\blpapi3.jar")

R version 2.11.1 (2010-05-31)
rJava Version 0.8-4
RBloomberg Version 0.4-142
Java environment initialized successfully.
Error in .jnew("org/findata/blpwrapper/Connection", java.log.level) :
? java.lang.NoClassDefFoundError: org/findata/blpwrapper/Connection

2) The file exists in the path I use in blpConnect (C:\Program Files\blp\API)
3) As in UPGR <GO> everything seems to be up to date:

.....

I'm still thinking it is an Rjava problem but got no idea how to get around with it. Maybe it is a lack of permissions under my machine at work.
Any clues?

Thanks very much.

Nacho.

Hi, Nacho,

Please try the following and let me know how they work.

1) Connect just as

cn <- blpConnect()

2) Do you have a file called blpapi3.jar in C:\Program Files\blp\API
or its subdirectories? If so what is the exact path to this file.

3) Can you upgrade to the most recent version of the Bloomberg API
(probably need to ask your IT department if you don't have admin
rights)

Hi there.
I am getting an error when trying to establish a connection to Bloomberg
with the RBloomberg library (java version, RDCOMclient version is hopeless
for me as I don't have administrative rights on my XP machine).
This is my code:

library(RBloomberg)

# blpapi3.jar file not in default directory
cn <- blpConnect(blpapi.jar.file="c:\\Program Files\\blp\\API\\blpapi3.jar")

the response:

R version 2.11.1 (2010-05-31)
rJava Version 0.8-4
RBloomberg Version 0.4-142
Java environment initialized successfully.
Error in .jnew("org/findata/blpwrapper/Connection", java.log.level) :

I am a complete java ignorant, but I got to find that it seems like the
.jaddClassPath() funtion is not working properly, extracted and modified
from blpConnect.Java:

.jclassPath()

[1] "C:\\PROGRA~1\\R\\R-211~1.1\\library\\rJava\\java"

.jaddClassPath("c:\\Program Files\\blp\\API")
.jclassPath()

[1] "C:\\PROGRA~1\\R\\R-211~1.1\\library\\rJava\\java"

blpwrapper.jar.file

[1] "C:/PROGRA~1/R/R-211~1.1/library/RBloomberg/java/blpwrapper.jar"

.jaddClassPath(blpwrapper.jar.file)
.jclassPath()

[1] "C:\\PROGRA~1\\R\\R-211~1.1\\library\\rJava\\java"

blpapi.jar.file

[1] "c:\\Program Files\\blp\\API\\blpapi3.jar"

.jaddClassPath(blpapi.jar.file)
.jclassPath()

[1] "C:\\PROGRA~1\\R\\R-211~1.1\\library\\rJava\\java"

I also enclose this code:

sessionInfo()

R version 2.11.1 (2010-05-31)
i386-pc-mingw32

locale:
[1] LC_COLLATE=English_United States.1252 ?LC_CTYPE=English_United

attached base packages:
[1] stats ? ? graphics ?grDevices utils ? ? datasets ?methods ? base

other attached packages:
[1] RBloomberg_0.4-142 rJava_0.8-4 ? ? ? ?svIDE_0.9-49

loaded via a namespace (and not attached):
[1] svMisc_0.9-57 tcltk_2.11.1 ?tools_2.11.1 ?XML_3.1-0


Any clue of what could be happening?.
Thanks very much in advance.

Nacho.
