}

**This one loops but never actually executes the http request:**

package rtwsimulation

import bootstrap.\_  
import scala.util.Random

class RTW extends Simulation {  
//val browsers = java.lang.Integer.getInteger(“users”, 1)  
//val rampUp = java.lang.Long.getLong(“ramp”,0L)  
//val howManyTimes = Integer.getInteger(“loop”,1)  
//val ip = java.lang.System.getProperty(“ipaddress”)  
//val port = java.lang.System.getProperty(“appport”)  
val browsers = 10  
val rampUp = 10  
val howManyTimes = 1000  
val regions = 4  
val exuri = “[http://9.12.43.169:9080/RTW](http://9.12.43.169:9080/RTW)”  
val inuri = “[http://10.1.20.169:9080/RTW](http://10.1.20.169:9080/RTW)”  
val exuris = “[https://9.12.43.169:9443/RTW](https://9.12.43.169:9443/RTW)”  
val inuris = “[https://10.1.20.169:9443/RTW](https://10.1.20.169:9443/RTW)”

val httpConf = httpConfig  
.baseURL(exuri)  
.acceptCharsetHeader(“ISO-8859-1,utf-8;q=0.7,_;q=0.7")  
.acceptHeader("text/html,application/xhtml+xml,application/xml,application/json;q=0.9,_/\*;q=0.8”)  
.acceptEncodingHeader(“gzip, deflate”)  
.acceptLanguageHeader(“fr,fr-fr;q=0.8,en-us;q=0.5,en;q=0.3”)  
.disableFollowRedirect

var i=0  
while (i \< howManyTimes) {  
var region = Random.nextInt(regions) + 1  
var program = Random.nextInt(7)  
var fullUri = “/RTWServlet?regions=” + region + “&program=” + program  
var scn = scenario(“Scenario Name” + i) // A scenario is a chain of requests and pauses  
exec(http(“request\_” + i).get(fullUri).basicAuth(“LBTYUA”, “LBTYUA”))  
.pause(2)  
i += 1  
setUp(scn.users(browsers).ramp(rampUp).protocolConfig(httpConf))  
}  
}

**I am not sure why but it does not execute the http requests and it dumps trying to report:**

Users : [#################################################################]100%  
waiting:0 / running:0 / done:10  
---- Scenario Name293 ----------------------------------------------------------  
Users : [#################################################################]100%

You use Gatling 1 that we have EOL’ed. Please first upgrade to Gatling 2.

I tried to upgrade yesterday, gatling does a check to make sure the level of SDK is 7U6 or above. This check fails for IBM SDKs. I run on zLinux, the only SDK for zLinux is IBM. Was considering how to proceed with the problem?
