Description
We have two EAP servers: server A and server B;
On server A we deploy an application which exposes some REST endpoints;
On server B we deploy an application which exposes some remote EJBs;
When the REST endpoints on server A are invoked, server A tries and invokes a remote EJB on server B;
Server A Server B
┌─────────────────┐ ┌────────┐
│ │ │ │
HTTP call-----> REST---> EJB ----------> EJB │
│ │ │ │
└─────────────────┘ └────────┘
When the deployments on server A and server B are "root" deployments (ROOT.war) the remote invocation fails with the following error:
[0m[31m09:00:29,438 ERROR [org.jboss.as.ejb3.invocation] (default task-1) WFLYEJB0034: Jakarta Enterprise Beans Invocation failed on component BasicClientStateless for method public java.lang.String org.jboss.as.quickstarts.xa.client.BasicClientStateless.passTxStatelessStateless(org.jboss.as.quickstarts.xa.client.LookupHelper$LookupType): jakarta.ejb.EJBException: java.lang.RuntimeException: jakarta.ejb.NoSuchEJBException: WFLYEJB0056: Could not find Jakarta Enterprise Beans in matching deployment: StatelessEJBLocator for "/ROOT/BasicServerStateless1", view is interface org.jboss.as.quickstarts.xa.server.BasicServerRemote1, affinity is None

See the attached file tx-client-0-tx-client(11).log for complete log;
The error happens only when using server configuration for remote look-up (see method lookupRemoteEJBOutbound i n class LookupHelper in the reproducers):
private static <T> T lookupRemoteEJBOutbound(String beanImplName, Class<T> remoteInterface, boolean isStateful, Properties ejbProperties) throws NamingException {
final Properties jndiProperties = new Properties();
if (ejbProperties != null) jndiProperties.putAll(ejbProperties);
jndiProperties.put(Context.URL_PKG_PREFIXES, JNDI_PKG_PREFIXES);
final Context context = new InitialContext(jndiProperties);
String lookupEjbStr = "ejb:/" + REMOTE_DEPLOYMENT_NAME + "/" + beanImplName + "!"
+ remoteInterface.getName() + (isStateful ? "?stateful" : "");
log.info("[LOOKUP] EJB lookup string: " + lookupEjbStr);
return (T) context.lookup(lookupEjbStr);
}
the server configuration is:

/subsystem=remoting/remote-outbound-connection=remote-ejb-connection:add(outbound-socket-binding-ref=remote-ejb, username=ejb, protocol=http-remoting)

the client jboss-ejb-client.xml file is:

There is no error with direct invocation (see method lookupRemoteEJBDirect in class LookupHelper in the reproducers):
