Relevant part of the stacktrace is:

Caused by: java.lang.ClassCastException: java.util.ArrayList cannot be cast to session.HostsList
at session.HostBean.register(HostBean.java:71)

When we take a look to the row 71 in HostBean.java, we will find following:

return (HostsList) Host.hosts;

As stacktrace says, Host.hosts is not a HostList . Also it cannot be because type of of hosts is something that implements java.util.List, in this case runtime type is ArrayList:

public transient static List<Host> hosts = new ArrayList<Host>();

HostList can be constructed and then returned as follows (in line 71 in HostBean.java):

HostsList hl = new HostList();
hl.setHosts(host.hosts);
return hosts;
