NAMEopenejb start - OpenEJB Remote Server SYNOPSISopenejb start OPENEJB:options NOTEThe OpenEJB Remote Server can be started by running the openejb.bat script for windows and the openejb script for Linux and other Unix based OSes. Before running these scripts you need to set the environment variable OPENEJB_HOME to the path of the directory where you unpacked the OpenEJB installation. From now on we will refer to this directory as <OPENEJB_HOME> and assume that you unpacked OpenEJB into the directory C:\openejb-3.0 The startup scripts are present in the <OPENEJB_HOME>/bin directory. You can set this directory in the system PATH for starting openejb from the command shell. In Windows, the remote server can be executed as follows: C:\openejb-3.0> bin\openejb start In UNIX, Linux, or Mac OS X, the deploy tool can be executed as follows: [OPENEJB:user@host openejb-3.0]# ./bin/openejb start Depending on your OpenEJB version, you may need to change execution bits to make the scripts executable. You can do this with the following command. [OPENEJB:user@host openejb-3.0]# chmod 755 bin/openejb From here on out, it will be assumed that you know how to execute the right openejb script for your operating system and commands will appear in shorthand as show below. openejb start -help DESCRIPTIONStarts OpenEJB as an EJB Server that can be accessed by remote clients via the OpenEJB Remote Server. ALWAYS check your openejb.log file for warnings immediately after starting the Remote Server. OpenEJB issues warnings when it works around a potential problem, encounters something it didn't expect, or when OpenEJB wants to let you know something may not work as you expected it. OpenEJB itself is configured with the OpenEJB configuration file, which is extremely simple and self-documenting. This file is located at c:\openejb-3.0\conf\openejb.xml. OPTIONS
EXAMPLESExample: Simplest scenarioopenejb start That's it. The ejbd will start up and bind to IP 127.0.0.1 and port 4201. The following properties would then be used to get an InitialContext from the Remote Server. java.naming.factory.initial = org.apache.openejb.client.RemoteInitialContextFactory
java.naming.provider.url = ejbd://127.0.0.1:4201
java.naming.security.principal = myuser
java.naming.security.credentials = mypass
Example: --conf=fileopenejb start --conf=C:\openejb-3.0\conf\mytest.conf Sets the openejb.configuration system variable to the file C:\openejb\conf\mytest.conf. When the server starts up and initializes OpenEJB, this configuration will be used to assemble the container system and load beans. Example: --local-copyopenejb start --local-copy=true Instructs the container system to marshal (ie, copy) all calls between beans are required by the EJB 1.1 specification. openejb start --local-copy=false Instructs the container system to not marshal (copy) calls between beans. The container system as will pass parameters and return values without copying or marshalling as is required for EJB 2.0 Local interfaces. CONFIG OVERRIDE EXAMPLESExample: -D<service>.bind=<address>openejb start -Dejbd.bind=10.45.67.8 This is the most common way to use the EJBd Server Service. The service will start up and bind to IP 10.45.67.8 and port 4201. The following properties would then be used to get an InitialContext from the EJBd Server Service. java.naming.factory.initial = org.apache.openejb.client.RemoteInitialContextFactory
java.naming.provider.url = ejbd://10.45.67.8:4201
java.naming.security.principal = myuser
java.naming.security.credentials = mypass
DNS names can also be used. openejb start -Dejbd.bind=myhost.foo.com The following properties would then be used to get an InitialContext from the Remote Server. java.naming.factory.initial = org.apache.openejb.client.RemoteInitialContextFactory
java.naming.provider.url = ejbd://myhost.foo.com:4201
java.naming.security.principal = myuser
java.naming.security.credentials = mypass
openejb start -Dtelnet.bind=myhost.foo.com The following properties would then be used to log into the server via a telnet client as such: telnet myhost.foo.com 4202 Example: -D<service>.port=<port>openejb start -Dejbd.port=8765 The server will start up and bind to IP 127.0.0.1 and port 8765. The following properties would then be used to get an InitialContext from the Remote Server. java.naming.factory.initial = org.apache.openejb.client.RemoteInitialContextFactory
java.naming.provider.url = ejbd://127.0.0.1:8765
java.naming.security.principal = myuser
java.naming.security.credentials = mypass
openejb start -Dhttpejbd.port=8888 The server will start up and the EJB over HTTP service will bind to IP 127.0.0.1 and port 8888. The following properties would then be used to get an InitialContext from the HTTP/Remote Server. java.naming.factory.initial = org.apache.openejb.client.RemoteInitialContextFactory
java.naming.provider.url = http://127.0.0.1:8888/openejb
java.naming.security.principal = myuser
java.naming.security.credentials = mypass
Example: -D<service>.only_from=<addresses>openejb start -Dadmin.only_from=192.168.1.12 Adds 192.168.1.12 to the list of IP addresses that are authorized to shutdown the server or access the server Multiple hosts can be given administrative access to this server by listing all the host names separated openejb start -Dadmin.only_from=192.168.1.12,joe.foo.com,robert The first host in the string names the host explicitly using an IP address (192.168.1.12). The second host uses a DNS name (joe.foo.com) to refer to the hosts IP address. The DNS name will be resolved and the IP will be added to the admin list. The third address refers to a the host by a name (robert)that the opperating system is able to resolve into a valid IP address. This is usually done via a hosts file, interal DNS server, or Windows Domain Server. Example: -D<service>.threads=<max>openejb start -Dejbd.threads=200 Sets the max number of concurrent threads that can enter the EJBd Server Service to 200. Example: -D<service>.disabled=<true/false>openejb start -Dtelnet.disabled=true Prevents the Telnet Server Service from starting when the OpenEJB Server starts. CONSOLE OUTPUTOnce you start OpenEJB using the openejb start command the following output will be seen on the console Apache OpenEJB 3.0 build: 20070825-01:10
