SSH

Connecting To OpenEJB or TomEE Through SSH

Description

It can be very useful to connect to the server to get some information.

Solution

For such a case OpenEJB/TomEE proposes to start with the Java EE server an SSH server. Currently, the security is based on JAAS (see how to configure JAAS for TomEE for more information about it).

Installation

Simply extract the openejb-ssh jar in the lib of tomee (webapps/tomee/lib) or openejb libs (lib folder). Then simply connect using your JAAS credential.

Note: you can use the provisioning features of openejb to do this job!

Then simply activate the service manage: it is done setting the system property openejb.servicemanager.enabled to true.

Note: it can be done through the conf/system.properties file. Note2: please take care to not add space after true (not 'true ' for instance).

OpenEJB SSH Shell

Once you are connected you get some commands:

  • deploy : deploy an application

  • undeploy : undeploy an application

  • list: list deployed EJBs

  • classloader : print the classloader tree of the app specified by the id

  • jmx : interact with JMX jmx list: list mbeans jmx get ** jmx set

    • jmx invoke ([, …​)

  • properties: print server configuration as properties

  • script

    + : execute the following script code using the following language with the JSR 223

  • script file

    + : execute the following script using the language (from the extension of the file) with the JSR 223

  • ls []: list the file in path is specified or in the base of the server if not

  • cat : print a file

  • part - : print the part of a file

Note1: JSR 223 can need to add some jar to openejb/tomee lib folder (groovy-all for instance to use groovy) Note2: ls, part, cat commands have to use $home and $base properties to specify the path
