How to get offline message from Tigase pubsub in smack library in android

Question

I have integrated Tigase server and I want to store pubsub offline message and retrive all of it when user get online.

For Ex: User_A and User_B is connected, if User_A sends message to User_B and at that time User_B is offline. then in which location that message goes? Now User_B is online but he didn't get any message. So How to retrieve that offline message?

Does we have to set some properties in init.properties file regarding this?

Here is my init.properties file content which sets the option to configure Tigase server.

--comp-class-1 = tigase.muc.MUCComponent
--virt-hosts = test
--user-db-uri = jdbc:mysql://localhost/tigasedb?user=tigase&password=tigase12
--user-db = mysql
--admins = admin@test
--comp-name-4 = message-archive
--comp-name-3 = rest
config-type = --gen-config-def
--comp-name-2 = pubsub
--comp-name-1 = muc
--cluster-mode = false
--sm-plugins = +message-archive-xep-0136,jabber:iq:register,jabber:iq:auth,urn:ietf:params:xml:ns:xmpp-sasl,urn:ietf:params:xml:ns:xmpp-bind,urn:ietf:params:xml:ns:xmpp-session,roster-presence,jabber:iq:privacy,jabber:iq:version,http://jabber.org/protocol/stats,starttls,vcard-temp,http://jabber.org/protocol/commands,jabber:iq:private,urn:xmpp:ping
--debug = server,xmpp.impl,db,pubsub,component,components
--comp-class-4 = tigase.archive.MessageArchiveComponent
--comp-class-3 = tigase.http.rest.RestMessageReceiver
--comp-class-2 = tigase.pubsub.PubSubComponent
