to WildFly

Hi,

I have a wildfly 18 config that has been working well for http and https remote ejb calls. However I am now trying to move this config behind a proxy server.

Putting the same config behind the proxy causes an org.xnio.http.UpgradeFailedException in the xnio library when trying to perform an EJB lookup from the client (full stack trace below).

Here are my config settings in my test case:

props.put(Context.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");
props.put(Context.PROVIDER_URL, providerurl);
props.put("jboss.naming.client.ejb.context", true);
props.put(Context.SECURITY_PRINCIPAL, CLIENT_EJB_USER_NAME);
props.put(Context.SECURITY_CREDENTIALS, CLIENT_EJB_PWD);
props.put(Context.URL_PKG_PREFIXES,"org.jboss.ejb.client.naming");
props.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", true);
props.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_STARTTLS", true);

I am looking for suggestions on either property config changes or an alternate library to invoke. Any help is appreciated.

Thanks,

Jim
