Hi,
I think you can just do something like read the parameters into R, and
then use the "parameters" argument of the .jinit function. Something
like this perhaps:
props <- readLines( "app.properties" )
props <- strsplit( gsub( "\\\t", "", grep( "=", props, value = TRUE )
), "=" )
params <- sapply( props, function(x){
sprintf( "-D%s=%s", x[1], x[2] )
} )
library(rJava)
.jinit(classpath="D:/R_BTE_Jar/BTE/BackTestingApp.jar",
parameters= c( "-Xmx512m", params ) )
Let me know if this works.

Hi Romain,
Attached is my R script that script I put into the R work space and
through source(“RScriptToCallJava.R”) command I call the script and my
java application is execute.
Is it the proper way to call the java application? If not, then please
can you explain the directory structure that needs for java application?
In java I used the property file. but when I load the property file
using .jaddClassPath("D:/R_BTE_Jar/BTE/app.properties") command, it is
not load.
Thanks Romain for your response.

Hi,
The file did not make it through the mailing list. Maybe you are looking
for ?read.dcf
Can you describe the way your application interacts with R.
