Websocket Extention 3.0.0.18 on Lucee 7 does not seem to work

MiniFireDragon · March 27, 2026, 4:44am

Not sure how to troubleshoot this issue, ie; is it Tomcat or Lucee not working.

My installation is downloading the Lucee 7 installer and running it, so there is no strange folder configurations, etc.

When I installed with extention, it did not create a websocket.json file. I put the websockets folder in

/opt/lucee/tomcat/lucee-server/context/websockets
also tried
/opt/lucee/tomcat/lucee-server/context/context/websockets

And even my webroot folder. Inside the folder I placed a file called test.cfc (well, each folder had an added letter so I knew what file I was hitting).

inside this test.cfc:

`component hint=“used to test websocket client” {

public static function onFirstOpen( wsclients ) {}

function onOpen( wsclient ) {}

function onOpenAsync( wsclient ) {}

function onMessage( wsclient, message ) {}

function onClose( wsclient, reasonPhrase ) {}

function onError( wsclient, cfcatch ) {}

public static function onLastClose() {}

}`

inside the test.cfm file I created (javascript script tags):

`
const socket = new WebSocket(“wss://dev.example.com/ws/test”);

socket.onopen = function (evt) {
console.log(“Connected”);
socket.send(“Hello, Lucee Extension!”);
};

socket.onmessage = function (event) {
console.log(“Received:”, event.data);
};

socket.onclose = function (evt) {
console.log(“Connection closed”);
};

socket.onerror = function (error) {
console.error(“WebSocket error:”, error);
};
`

And the page just returns an unable to connect error. And yes, I restarted the lucee server each time I made the websockets folder and the test.cfc file in different location. The admin panel does not have a websockets mapping (I do not know if it should). And the Catalina.log spits this out:

I also setup the websocket.log file set to trace as suggested by the document page. It did do something for a few seconds:

I am currently on:
Lucee 7.0.2.106 Apache Tomcat/11.0.13 Java: 21.0.9 (Eclipse Adoptium) 64bit

I think I covered all the questions.

Zackster · March 27, 2026, 4:56am

always a good bet to try the latest SNAPSHOT if newer than the stable release

MiniFireDragon · March 27, 2026, 5:13am

That is my next step. Just wanted to report my finding here since it is in the release column.

MiniFireDragon · March 27, 2026, 5:25am

Went to the 3.0.0.20 snapshot and have similar results. No websocket.json file is created. But there is no error in Catalina this time. I restarted Tomcat to make sure that was not the hold up.

MiniFireDragon · March 27, 2026, 2:15pm

I check in on Websocket.log and it starts with:

Still cannot find a websocket.json, and the test page still will not connect to a websocket.

MiniFireDragon · March 27, 2026, 9:24pm

Websockets still is not working correctly. But I have gotten further.

I went to the local machine to do some testing since I think apache was disrupting the wss connection.

I removed the extention, I restart Lucee. I reloaded the extention, still no websocket.json file. However, I did manage to finally get websockets to build a JSON file, I had to run:

<cfdump var="#websocketInfo()#" />

After I ran that, websockets “woke up”. And no matter how many times I restarted lucee, this would spill out into the log:

"INFO","https-jsse-nio-8443-exec-2","03/27/2026","17:09:08","","websocket-endpoint-factory","init WebSocketEndpoint"
"WARN","https-jsse-nio-8443-exec-2","03/27/2026","17:09:08","","websocket-endpoint-factory","calling [onOpen] via reflection, Lucee restart needed!"
"WARN","https-jsse-nio-8443-exec-2","03/27/2026","17:09:08","","websocket-endpoint-factory","calling [onError] via reflection, Lucee restart needed!"

So I restarted Tomcat. The above messages went away, but the error was still there.

The log is producing errors:

From the browser I would get connected and immediatly disconnected.

MiniFireDragon · March 28, 2026, 2:40am

While testing the different snapshots trying to get one to work, I found out that if I install the release websocket, restart Lucee, run the test page above, then upgrade to the snapshot, followed by a restart, I do not get an immediate disconnect. Here is the log from When I upgraded back to the 3.0.0.20-Snapshot and restarted Lucee. Ran that page, then restarted Tomcat.

Just for clarity, where it says Lucee needs to be restarted in the above log, I had already restarted Lucee. When I restart Tomcat the needing to restart Lucee goes away, but the websocket gives the error about “cw”.

And I just tried a Lucee restart, and the “cw” error goes away, but Lucee complains about needing to be restarted again.
