Can you retry without starting any RGUI ? Rsession is supposed to start it by itself. Also, check that no remaining Rserve is still alive in your process exporer.

oh,yes, I found that:
Rsession is supposed to start it by itself.
when pass RserverConf conf = new RserverConf(null, -1/* RserverConf.RserverDefaultPort/, null, null, prop);* to s = Rsession.newInstanceTry(l, conf); as code in 'public void setUp() {'
But ,when null was passed in the test report "java.lang.NullPointerException" and no new rserve process in the exporer ** as code in testHardConcurrency()
//@Test
public void testHardConcurrency() throws REXPMismatchException, InterruptedException {
final int[] A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
final Rsession[] R = new Rsession[A.length];
for (int i = 0; i < R.length; i++) {
R[i] = Rsession.newInstanceTry(new Logger() {
public void println(String string, Level level) {
if (level == Level.INFO) {
System.out.println(string);
} else {
System.err.println(string);
}
}
public void close() {
}
}, null); ** // when null was passed in then the test report "java.lang.NullPointerException" and no new rserve process in the exporer **
}
Maybe Passing null values is not correct? I want to know What functions do have when you pass a null value
from rsession.
ok, you can use
RserverConf conf = new RserverConf("localhost", 6311, mylogin, mypasswd, prop)
to reach your Rserve instance.
null values is supposed to startup a new Rserver which is not working for you, it seems.

Thank you
