TIBCO embedes the tomcat to handle the HTTP requests in the HTTP starter activity. This error happened while executing the send HTTP response activity with close connection option.

Answer 1

I’ve tried a workaround which is splitting writing the response into two parts :

1. HTTP response activity for flushing the response to the client to make sure that the client have received the response data.
2. HTTP response activity for closing the connection.

I hope this could help!
