# ============================================================================== # # Example of using Jini as Lookup service - registering and looking up # an RMI Connector (IIOP/JRMP) # # ============================================================================== # # Requirements: # # Before running this example you will have to: # --------------------------------------------- # # Get and install Jini: # # http://www.jini.org/ # http://jini.dev.java.net/ # http://starterkit.dev.java.net/downloads/index.html # # This example has been implemented using the Jini Technology Starter Kit # Version 1.2.1_002. # # If you wish to use an external directory for the RMI JMX Connectors # (URLs of the form jmx:service:[rmi|iiop]:/host:port/jndi/jndi-url) # then: # # o If you wish to use rmiregistry in conjunction with the RMI/JRMP # JMX Connector you will have to start a rmiregistry (see below). # # o If you wish to use CORBA Naming Service in conjunction with the RMI/IIOP # JMX Connector you will have to start an ORB daemon (see below). # # o If you wish to use LDAP in conjunction with the RMI JMX Connectors # you will have to install/setup a directory server # # In order to compile and run the example, make a copy of this README file, and # then simply cut and paste all the commands as needed into a terminal window. # # This README makes the assumption that you are running under Java SE 6 on Unix, # you are familiar with Jini, the JMX technology, with LDAP and JNDI, and with # the bourne shell or korn shell syntax. # # All the commands below are defined using Unix korn shell syntax. # # If you are not running Unix and korn shell you are expected to be able to # adapt these commands to your favorite OS and shell environment. # # Update & define the following variables to match your local installation: # JINI_HOME=@INSTALL_HOME_FOR_JINI@ # Define the following variables: # JINILIB=$JINI_HOME/lib classp=$JINILIB/jini-core.jar:$JINILIB/jini-ext.jar # Create a jini.properties file, either from # $JINI_HOME/example/launcher/jini12_.properties # or from the jini.properties.template file # provided in this example for the Unix platform. # Replace the paths and hostnames (default is localhost) where needed in the # jini.properties file. # Launch Jini StartService example: # java -classpath $JINILIB/jini-examples.jar com.sun.jini.example.launcher.StartService & # Load the edited jini.properties file in the launcher tool. # Use Jini StartService example to start: # * RMID, # * WebServer, # * Reggie, # * and LookupBrowser #------------------------------------------------------------------------------- # Start an rmiregistry # rmiregistry 9999 & #------------------------------------------------------------------------------- # Start an ORB daemon: # rm -rf ./orb.db orbd -ORBInitialPort 7777 & #------------------------------------------------------------------------------- # Start an LDAP Server, and create a new dc=Test suffix inside. # # (only needed if you wish to register the RMI or IIOP # stubs in LDAP, instead of using CORBA Naming Service or RMI registry) # # On Solaris 9 you should first login as root and execute # the following commands: # Setup an LDAP server (you don't need to do this if the # server has already been configured). # /usr/sbin/directoryserver setup # Start the console, and if needed create a new suffix, a database, # and a root node (e.g. dc=Test) # /usr/sbin/directoryserver startconsole # NOTE: if you're not using Solaris 9 Directory Server you will have # to make sure the Java Schema (RFC 2713: # http://www.ietf.org/rfc/rfc2713.txt) is known by that server #------------------------------------------------------------------------------- # Compile Server.java and Client.java # # * Server.java: creates an MBeanServer, creates and starts an # RMI connector (JRMP/IIOP) # * Client.java: lookup a connector in Jini # list all MBeans. javac -d . -classpath $classp Server.java Client.java #------------------------------------------------------------------------------- # LDAP parameters: # Supply the appropriate hostname below, and define this variable: # ldaphost=gigondas # Supply the appropriate port number below, and define this variable: # ldapport=6666 # Supply the appropriate principal below, and define this variable: # principal="cn=Directory Manager" # Supply the appropriate credentials below, and define this variable: # credentials= #------------------------------------------------------------------------------- # JNDI URLs # jndirmi="rmi://localhost:9999" jndiiiop="iiop://localhost:7777" jndildap="ldap://$ldaphost:$ldapport" #------------------------------------------------------------------------------- # JMX Service URLs # jmxiiopurl="service:jmx:iiop:///jndi/${jndiiiop}/server" jmxrmiurl="service:jmx:rmi:///jndi/${jndirmi}/server" jmxiiopldapurl="service:jmx:iiop:///jndi/${jndildap}/cn=x,dc=Test" jmxrmildapurl="service:jmx:rmi:///jndi/${jndildap}/cn=x,dc=Test" jmxstuburl="service:jmx:rmi://" jmxiorurl="service:jmx:iiop://" #------------------------------------------------------------------------------- # Below we illustrate the different JMX Connector Servers # which you have the choice to start. # There are seven cases labelled (a) to (f): # # * RMI Connectors # + over JRMP # - without any external directory (a) # - using rmiregistry as external directory (b) # - using LDAP as external directory (c) # + over IIOP # - without any external directory (d) # - using CORBA Naming Service as external directory (e) # - using LDAP as external directory (f) # NOTE-1: As defined in section 6.1 "Terminology" of the "JMX Remote API 1.0 # Specification" document, an agent is composed of one MBean Server and of # one or more Connector Servers. There can be several agents running in one JVM. # For flexibility of this example, the jini.Server class creates an agent which # is composed of one MBean Server and of only one Connector Server. The class # jini.Server decides which type of Connector Server to create depending on the # value given to the "url" system property when you start the example. # NOTE-2: The value of the "agent.name" system property is the value that the # jini.Server class will give to the "AgentName" lookup attribute when it # registers the connector's URL in the lookup service. As defined in Table 6.1 # "Lookup attributes for connectors" of the "JMX Remote API 1.0 Specification" # document: the "AgentName" lookup attribute is a simple name used to identify # the *AGENT* to which the connector is attached. It makes it possible to # search, with a query to the lookup service, for all the connectors registered # by a given agent. # (a) You can start an agent with an RMI Connector Server over JRMP # without using any external directory # java -classpath .:$classp -Ddebug=true \ -Dagent.name=test-server-a \ -Durl="service:jmx:rmi://" \ -Djava.security.policy=java.policy \ jini.Server & # (b) Or you can start an agent with an RMI Connector Server over JRMP # using rmiregistry as external directory # (Start rmiregistry first, if not yet started) # java -classpath .:$classp -Ddebug=true \ -Dagent.name=test-server-b \ -Durl="service:jmx:rmi:///jndi/${jndirmi}/server" \ -Djava.security.policy=java.policy \ jini.Server & # (c) Or you can start an agent with an RMI Connector Server over JRMP # using LDAP as external directory # (First start an LDAP server and create the dc=Test suffix) # java -classpath .:$classp -Ddebug=true \ -Dagent.name=test-server-c \ -Durl="service:jmx:rmi:///jndi/${jndildap}/cn=x,dc=Test" \ -Djava.security.policy=java.policy \ -Djava.naming.security.principal="$principal" \ -Djava.naming.security.credentials="$credentials" \ jini.Server & # (d) Or you can start an agent with an RMI Connector Server over IIOP # without using any external directory # java -classpath .:$classp -Ddebug=true \ -Dagent.name=test-server-d \ -Durl="service:jmx:iiop://" \ -Djava.security.policy=java.policy \ jini.Server & # (e) Or you can start an agent with an RMI Connector Server over IIOP # using CORBA Naming Service as external directory # (Start ORBD first if not yet started). # java -classpath .:$classp -Ddebug=true \ -Dagent.name=test-server-e \ -Durl="service:jmx:iiop:///jndi/${jndiiiop}/server" \ -Djava.security.policy=java.policy \ jini.Server & # (f) Or you can start an agent with an RMI Connector Server over IIOP # using LDAP as external directory # (First start an LDAP server and create the dc=Test suffix) # java -classpath .:$classp -Ddebug=true \ -Dagent.name=test-server-f \ -Durl="service:jmx:iiop:///jndi/${jndildap}/cn=x,dc=Test" \ -Djava.security.policy=java.policy \ -Djava.naming.security.principal="$principal" \ -Djava.naming.security.credentials="$credentials" \ jini.Server & # Once you have started one or more agents, you can start the Client. # java -classpath .:$classp -Ddebug=true \ -Djava.security.policy=java.policy \ jini.Client #-------------------------------------------------------------------------------
