Question: Assume you imported a package, say unittest2
if you were using Windows IDLE, if you press:
unittest2.
a small help window will pop up and show the list of functions you can use, similarly how can I get this small pop up on linux ?

Am accessing a linux box from putty

Answer: 
After a couple of weeks I got back to the problem and found the solution. The problem was - of course - in configuration and had nothing in common with the particular version of Wildfly. Mode specifically:

There were three nodes in the domain and three servers in each node. All nodes were launched with the following property: 

```
-Djboss.node.name=nodeX

```

...where `nodeX` is the name of a particular node. However, it meant that all three servers in the node get the same name, which is exactly what confused the load balancer.
As soon as I have removed this property, everything started to work.
I ran into the Node Removed issue to.
I managed to solve it by using the following as instance-id

```
<subsystem xmlns="urn:jboss:domain:undertow:2.0" instance-id="${jboss.server.name}">

```

I hope this will help someone else to ;)
