Hi Romain, Exactly this is the script which I need. Thanks a lot for helping. Romain, Is there any way to modified a particular line in the property file through R script? If yes then please explain how.
Cheers!

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.
