Hi, I installed SJava 0.66-1 on my linux RH 7.2 machine. I am using R-1.7.1. I set LD_LIBRARY_PATH up then called library(SJava) and it was fine. But when I called .JavaInit(), I got weird error that states it could not find java/lang/Hashtable. The session is below and shows my java configuration. I am using j2sdk1.4.2_01 from Sun. Thank you very much. Weiming Zhang > .javaConfig $classPath [1] "/usr/lib/R/library/SJava/org/omegahat/Jars/Environment.jar&qu...

Does SJava require that omegahat be installed? I have installed the binary Windows package (SJavaWin_0.62-8.zip), made the change eliminating the call to .alias(), with the following results on startup: > library(SJava) > .JavaInit() Error in .JavaInit() : Couldn't start Java Virtual Machine: Cannot find the Omegahat interface manager class.

Dear R users, I was happy to find a binary library for SJava in the last released of R (1.5.1)... I am able to load the library... but I have some problems to run this library: > .JavaInit() Error in .JavaInit() : Couldn't start Java Virtual Machine: Can't create Java Virtual Machine > javaConfig() $classPath [1] "F:/Program Files/R/rw1051/library/SJava/org/omegahat/Jars/Environment.jar" [2] "F:/Program Files/R/rw1051/library/SJava/org/.."...

...f the server, But, if I run theses examples on an “X11 client”, under Linux or windows, with a “correct configuration” of the X11 client (export DISPLAY=machine:0.0 on Linux for example), I have a “scratch” of the R session without any messages … For example: > library(SJava) > .JavaInit() > source(“DynamicButtonCallback.R”) Run perfectly on the server, with a creation of a button on the display. But the same instructions, on the X11 client, create the button and immediately crash the R session and destroy the button. Any Ideas? Thanks for your help. Laurent...
