object RecordSeqFeederBuilder is not a member of package io.gatling.core.feeder

HI All,

I am trying to connect to DB to fetch values form a table and use them as feed to my scenario. But I am getting the following error. Could someone please help resolving this issue?

object RecordSeqFeederBuilder is not a member of package io.gatling.core.feeder

class Extract_JDBC extends Simulation {

val s1 = new File(“src/test/resources/data/extractOP.csv”)
val url: String = “https://abc.com

private val dbConnectionString = “jdbc:oracle:thin:>>>>>>”
private val sqlQuery = “SELECT DCN FROM …”
private val sqlUserName = “abc”
private val sqlPassword = “12345”
private val message = “${DCN}”

val sqlQueryFeeder: RecordSeqFeederBuilder[Any] = jdbcFeeder(dbConnectionString,
//assigning base URL to a variable. we define the .baseURL() that will be prepended to all HTTP requests.

val httpProtocol = http.baseUrl(url)

//defining header for our http request. We can have multiple headers if our requests need different headers

val header = Map(
“Content-Type” → “application/soap+xml;charset=UTF-8”,
“Connection” → “alive”,
//“User-agent” → “Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:16.0) Gecko/20100101 Firefox/16.0”)
“User-agent” → “Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko”) //-----For Internet Explorer
//“User-agent” → “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.131 Safari/537.36”) //-----For Chrome
//defining object here to address our requests

object payload_myUHC{

val pl1 = scenario(“ExtractData”)


Adding the libraries which I ma importing for this:

import java.io.File
import java.io.PrintWriter
import java.io.FileOutputStream
import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration._
import io.gatling.jdbc.Predef._
import io.gatling.core.feeder
import io.gatling.core.config.GatlingConfiguration
import io.gatling.core.structure.ScenarioBuilder
import io.gatling.http.protocol.HttpProtocolBuilder
import io.gatling.core.feeder.RecordSeqFeederBuilder


Don’t use explicit return types, remove all of them and stick to the imports as defined in Gatling’s documentation:

import io.gatling.core.Predef._
import io.gatling.http.Predef._

Thank you!
I used the following code - sourcefeederbuilder and it stopped throwing me error for feeder atleast. Now I am having issue w.r.t. hava handshake error.

val sqlQueryFeeder: SourceFeederBuilder[Any] = jdbcFeeder(dbConnectionString,





I used the following code - sourcefeederbuilder

You’ll be sorry if we rename this class.
Just let the type implicit.
