The documentation for tRest states that you can increase the timeout in studio on the component but this will not work on the server and you need to edit a config file.
This option does not work in Talend Runtime. For ESB Deployments to Talend Runtime, this parameter will have no effect. In the configuration file <TalendRuntimePath>/container/etc/org.apache.cxf.http.conduits-common.cfg, you need a URL which covers you service, for example, url = http://.* to handle both HTTP and HTTPS requests, and specify the client.ConnectionTimeout parameter in milliseconds in this HTTP Conduit file. If you need to use the Receive timeout option, specify the client.ReceiveTimeout in milliseconds too.
but i can't find the file org.apache.cxf.http.conduits-common.cfg anywhere, there isn't even a container directory i can see on the server.
