Clustered session proxies load balance across different bindings on the same server
-----------------------------------------------------------------------------------
Key: EJBTHREE-2174
URL: https://jira.jboss.org/browse/EJBTHREE-2174
Project: EJB 3.0
Issue Type: Bug
Components: Clustering
Reporter: Brian Stansberry
With a bean config like this:
<session>
<ejb-name>HelloBean</ejb-name>
<remote-binding>
<jndi-name>HelloBean/http</jndi-name>
<client-bind-url>
http://${jboss.bind.address}:8080/unified-invoker/Ejb3ServerInvokerServlet/?return-exception=true
</client-bind-url>
</remote-binding>
<remote-binding>
<jndi-name>HelloBean/https</jndi-name>
<client-bind-url>
https://${jboss.bind.address}:8443/unified-invoker/SSLEjb3ServerInvokerServlet/?return-exception=true
</client-bind-url>
</remote-binding>
</session>
and client code like this:
51 Properties p = new Properties();
52 p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.naming.HttpNamingContextFactory");
53 p.put(Context.PROVIDER_URL,
"http://localhost:8080/unified-invoker/JNDIFactory/?return-exception=true");
54 p.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
55 Context ctx = new InitialContext(p);
56
57 //Hello bean = (Hello)
ctx.lookup("ProxyFactory/helloWorld/HelloBean/HelloBean/http");
58 Object o = ctx.lookup("HelloBean/http");
there is sometimes an attempt to connect via the HTTPS URL, which indicates the clustered
proxy sees the https binding as a 2nd target.
Stack trace showing the attempt to use HTTPS:
test:
[java] 17:20:02,578 ERROR [HTTPClientInvoker] Error creating SSL Socket Factory for
client invoker: Error initializing socket factory SSL context: Can not find truststore
url.
