Class HelloWorldSubscribe

java.lang.Object
  javaclients.HelloWorldSubscribe

All Implemented Interfaces:

I_Callback

public class HelloWorldSubscribe

extends java.lang.Object

implements I_Callback

This client connects to xmlBlaster and subscribes to messages.

This is a nice client to experiment and play with xmlBlaster as there are many command line options to specify the type and amount of messages published.

Try using 'java javaclients.HelloWorldPublish' in another window to publish some messages. Further you can type 'd' in the window running xmlBlaster to get a server dump.

Invoke (after starting the xmlBlaster server):

 java javaclients.HelloWorldSubscribe -xpath //key -initialUpdate true -unSubscribe true

 java javaclients.HelloWorldSubscribe -interactive false -oid Hello -initialUpdate true -unSubscribe true

 java javaclients.HelloWorldSubscribe -session.name joeSubscriber/5 -passwd secret -initialUpdate true -dump[HelloWorldSubscribe] true

 java javaclients.HelloWorldSubscribe -xpath //key -filter.type GnuRegexFilter -filter.query "^__sys__jdbc.*"

 java javaclients.HelloWorldSubscribe -xpath //key -filter.type XPathFilter -filter.query "//tomato"

 java javaclients.HelloWorldSubscribe -xpath //key -filter.type ContentLenFilter -filter.query "10"
 

If unSubscribe=false the message is not unsubscribed at the end, if disconnect=false we don't logout at the end.
