Subject: [jboss-user] How to supply SSLContext to undertow websocket
Message-ID: <26b7ae381d9d1fa2e0d89e33d6200729@jimmy.harvard.edu>

I'm writing an application I'm packaging as a war using maven that needs 
to make client side websocket connection via SSL. I saw 
http://lists.jboss.org/pipermail/undertow-dev/2016-March.txt and I'm 
trying to follow door number two, that is to implement 
io.undertow.websockets.jsr.WebsocketClientSslProvider and make the 
appropriate addition to META-INF/services. Undertow finds my class just 
fine but is unable to load it.

I add dependency on the undertow-websockets-jsr scoped provided since I 
hope it is provided by the container:

<dependency>
<groupId>io.undertow</groupId>
<artifactId>undertow-websockets-jsr</artifactId>
<version>1.2.9.Final</version>
<scope>provided</scope>
</dependency>

This yields in the following exception:

Caused by: java.lang.NoClassDefFoundError: org/xnio/ssl/XnioSsl
	at java.lang.Class.getDeclaredConstructors0(Native Method)
	at java.lang.Class.privateGetDeclaredConstructors(Class.java:2671)

I don't think I should be adding any runtime jars to my project, but for 
the sake of argument I tried adding the xnio jar containing XnioSsl as 
follows:

<dependency>
<groupId>org.jboss.xnio</groupId>
<artifactId>xnio-api</artifactId>
<version>3.3.1.Final</version>
</dependency>

Which now yields this exception:

I'd like to configure SSL this way, how do I make this happen?

Thanks in advance.
