Folks, I am trying to upgrade from R2.11.1 with RBloomberg 0.4-144 and rJava_0.8-6, in which setup I have no problems connecting and using Bloomberg. My Java environment is JRE 6. I see that some people have got RBloomberg 0.4-150 working under R2.13.1. It doesn't, however, for me: I am unable to establish a connection using conn <- blpConnect(blpapi.jar.file = 'C:/Program Files/blp/API/blpapi3.jar') Inside blpConnect.Java() the "Java environment is initialized successfully", but thereafter the call tree gets stuck at .jnew() and hangs. In .jnew(): o <- .External(RcreateObject, class, ..., silent = silent) is the line that hangs (class = "org/findata/blpwrapper/Connection", ... = "Java-Object(WARNING)", silent = FALSE) I thought I could backtrack to rJava 0.8-8, but that build is not available for R2.13 (and rJava is missing entirely for R2.12) on the CRAN. Any suggestions? Do I need a newer version of Java? Can anyone point me to rJava 0.8-8 for R2.13 that I could try out instead? sessionInfo() R version 2.13.1 Patched (2011-07-22 r56481) Platform: i386-pc-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=English_United Kingdom.1252 LC_CTYPE=English_United Kingdom.1252 LC_MONETARY=English_United Kingdom.1252 LC_NUMERIC=C LC_TIME=English_United Kingdom.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] RBloomberg_0.4-150 rJava_0.9-2 plotrix_3.2-2 PerformanceAnalytics_1.0.3.2 xts_0.8-0 zoo_1.7-2 loaded via a namespace (and not attached): [1] grid_2.13.1 lattice_0.19-31 Thanks, Murali
blpConnect hangs with RBloomberg 0.4-150 on R2.13.1

Hi Murali, I don't see anything obvious that would cause this to stop working for you on upgrade. One possibility could be that your Bloomberg API is installed in a non-standard directory, but that's not definitely the issue. It might be useful to look at your Java logs. First, try increasing the logging level like this: conn <- blpConnect(blpapi.jar.file = 'C:/Program Files/blp/API/blpapi3.jar', log.level = "info") The log will be in your Java home dir (possibly the same as your Windows home dir) named something like org.findata.blpwrapper.*.log. We're looking for an entry like "Session Started" or "Service Started" or something along those lines. Thanks, John

Hi John, Thank you for the response. I tried as you suggest. There are two logs created: org.findata.blpwrapper.0.log: 07-Sep-2011 11:24:54 org.findata.blpwrapper.Connection processSessionStatusEvent INFO: Session Started blpjavaapi0.log.0: 2011/09/07 11:24:53.981 [INFO] ********************************************************** 2011/09/07 11:24:54.340 com.bloomberglp.blpapi.impl.an a [INFO] Session established with: /127.0.0.1:8194 I replaced the log.level = "info" with = "finest", and it makes no difference - only these lines appear in either case. When I look at the successful connections with R2.11.1 and earlier rJava, I get no events in the org.findata* log, but exactly the same events in the blpjavaapi0.log.0 file. The blpConnect() call hangs and can't be escaped from without closing the R session. Baffled!
