Re: Issue running Websockets JSR356 with Tomcat 7.0.50 Embedded
Any hints? I would really appreciate if someone could provide some pointers
(e.g. classes involved etc) about the implementation of the mechanism used to
discover and deploy endpoints; I will then try to study the code in order to
figure out why it doesn't work when I set jarScanner.setScanClassPath(false)
Thanks,
Jacopo

I run this code from a folder containing the examples webapp and the Tomcat

Is there a way to deploy successfully the websockets with
setScanClassPath(false) ?

Well, actually in my unit test (posted in this thread) I am deploying the examples application of Tomcat, and the websockets in it are under the WEB-INF folder.

I would really appreciate if someone could provide some pointers (e.g. classes involved etc) about the implementation of the mechanism used to discover and deploy endpoints; I will then try to study the code in order to figure out why it doesn't work when I set jarScanner.setScanClassPath(false) The discovery is done with an SCI (javax.servlet.ServletContainerInitializer), as defined in tomcat7-websocket.jar/META-INF/services. The class name is org.apache.tomcat.websocket.server.WsSci. It seems that you prevented its discovery by skipping that jar in your JarScanner. You can also bootstrap web sockets by defining a listener in web.xml (org.apache.tomcat.websocket.server.WsContextListener). That listener just starts and shuts down the websocket engine, it does not scan for endpoints. http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/tomcat/websocket/server/WsContextListener.html Best regards, Konstantin Kolinko - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Hello all,
I did further tests and I have now implemented a test client that executes a
Tomcat embedded instance that is successfully running websockets.
The client code resembles quite closely what we are doing in OFBiz to prepare
the Tomcat instance... and I think I have found the settings that is causing
the issue in OFBiz.
When in OFBiz we create the Context objects we set in their JarScanner (we
use the StandardJarScanner): setScanClassPath(false)
I have noticed that if in my test client I set the same the websockets are
not mounted; they only work with setScanClassPath(true).
Since I doubt we will be able to set it to true in OFBiz, I would really
appreciate if you could provide some hints about the mechanism that Tomcat
uses to deploy websockets.
Am I completely off track?

Hello all,
I am trying to deploy and use Websockets using the Tomcat 7.0.50 *Embedded*

Some more details on my environment:

* I have mounted the examples webapp that comes with Tomcat (Core
distribution) using the Embedded Tomcat instance: all the examples work fine
(including the websocket-deprecated ones) except for the Websockets JSR356
ones
When I try to run the Websockets JSR356 examples, when I try to Connect
(either using the programmatic API or the annotation API) I get the message:
Info: WebSocket connection closed.
Nothing appears in the console.
Any hints would be greatly appreciated. Thanks in advance

[*] The reason I am using the Embedded version of Tomcat is that I am trying
to add support for Websockets to Apache OFBiz (ofbiz.apache.org) and OFBiz
runs Tomcat in embedded mode.
