How can I generate a 503 error by configuring tomcat?

Question

I want to configure my Apache Tomcat/8.5.37 by setting configuration attributes like maxThreads, maxConnections, acceptCount etc. in such a way, I can get 503 error in reply to a REST call by sending some concurrent requests (like 100 requests at a time). How can to do that?

Edit: I am getting 'connection refused' response in some cases. How can I get status 503 instead of 'connection refused'?

In server.xml file add following section

<Connector port="8080" protocol="HTTP/1.1"
           maxThreads="10"
           maxConnections="10"
           connectionTimeout="20000"
           redirectPort="8443"
           maxPostSize="209715200" />

Tried with this configuration. Then called 50 requests simultaneously. But all are processed in batch of 5. – naimul64 Jan 10 '19 at 08:37
You can simulate by adding the java code `Thread.sleep(10 or 15 min)` in your jsp / servlet page, so that the requests are running continuously. – Ramesh Subramanian Jan 11 '19 at 12:44
This is not an answer to the qustion. The question is how to response 503 instead of ECONNREFUSED. – Andrey Dobrikov May 31 '23 at 11:31
