Hi Guys,
In our implementation, we have a gateway app that uses jsr websockets to
communication with our main application server. In a small system, we want to
run them both on a single Tomcat instance using the same Tomcat NIO connector,
but directing to different respective WS paths. This works fine if you deploy
the MAIN first, then the GW - so that MAIN is already up and running. If you
restart Tomcat when both webapps are deployed - and the GW (client) starts
first, it hangs indefinitely in the following code trying to establish a WS
connection:
Is this a bug or a known limitation when a client/server in the same webapp try
to connect at startup?
Thanks
