Question

JSR223 Sampler return Response same as Request for EDIFACT message.
Request:
def payload = "UNB+IATA:1+1S+XX+121103+FF168019110033++ETK1+O'\n" +

Answer 1

If this code:
def payload = "UNB+IATA:1+1S+XX+121103+FF168019110033++ETK1+O'\n" +
"UNH+1+TKCREQ:00:1:IA'\n" +
"MSG+:131'\n" +
"ORG+1S+99999999:X7HH+VZX++T+GR+CXN'\n" +
"TKT+676713121:T'\n" +
"UNT+5+1'\n" +
"UNZ+1+FF168019110033"
is the complete code for the JSR223 Sampler - it does absolutely nothing.
If you want to send it over TCP you need to put the payload into "Text to send" field of the TCP Sampler:
If you want to send the "payload" using JSR223 Sampler you need to add the relevant code to do it, the simplest one is:
def payload = "UNB+IATA:1+1S+XX+121103+FF168019110033++ETK1+O'\n" +
"UNH+1+TKCREQ:00:1:IA'\n" +
"MSG+:131'\n" +
"ORG+1S+99999999:X7HH+VZX++T+GR+CXN'\n" +
"TKT+676713121:T'\n" +
"UNT+5+1'\n" +
"UNZ+1+FF168019110033"
def socket = new Socket('xxxxxx', 3432)
socket.withStreams { input, output ->
log.info(input.newReader().readLine())
output << payload
}
The output will go to jmeter.log file.

Sending Request in Jmeter as below:
import org.apache.jmeter.util.JsseSSLManager;
import org.apache.jmeter.util.SSLManager;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;
int your_app_port = 7XX0;
String your_app_host = 'XXXXXXX';
JsseSSLManager sslManager = (JsseSSLManager) SSLManager.getInstance();
SSLSocketFactory sslsocketfactory = sslManager.getContext().getSocketFactory();
SSLSocket sslsocket = (SSLSocket) sslsocketfactory.createSocket('XXXXXXX', 7XX0)
def sessInboundQueue = System.getProperties().get("SessionInbound")
def destinationInboundQueue = System.getProperties().get("DestinationInbound")
def payload = """UNB+IATA:1+1S+1D+201112:0204+FF168019119008++ETK1+O'
UNH+1+TKCREQ:00:1:IA'

TKT+9992170003108:T'

UNZ+1+FF168019119008'"""
def msg = sessInboundQueue.createTextMessage(payload)
Response:
Response code:500
Response message:javax.script.ScriptException: java.lang.NullPointerException: Cannot invoke method createTextMessage() on null object
Can some one help me?
