24.2. Advanced Understanding
Refer to the JOnAS sources for more details about the classes mentioned in this section.
24.2.1. JOnAS built-in Services
The existing JOnAS services are the following:
| Service name | Service class |
|---|---|
| registry | RegistryServiceImpl |
| ejb | EJBServiceImpl |
| ear | EarServiceImpl |
| dbm | DatabaseServiceImpl |
| jms | JmsServiceImpl |
| jmx | JmxServiceImpl |
| jtm | TransactionServiceImpl |
| MailServiceImpl | |
| resource | ResourceServiceImpl |
| security | JonasSecurityServiceImpl |
| ws | AxisWSService |
If all of these services are required, they will be launched in the following order: registry, jmx, security, jtm, dbm, mail, jms, resource, ejb, ws, web, ear.
jmx, security, dbm, mail, resource are optional when you are using service ejb.
registry must be launched first.
 | Notes |
|---|---|
For compatibility with previous versions of JOnAS, if registry is not set as the first service to launch, JOnAS automatically launches the registry service. Thus, the jtm service must be launched before these services. dbm, jms, resource, and ejb depend on jtm. ear depends on ejb and web (that provide the ejb and web containers), thus these services must be launched before the ear service. ear and web depend on ws, thus the ws service must be launched before the ear and web services. |
It is possible to launch a stand-alone Transaction Manager with only the registry and jtm services.
In this case, a jonas.properties file looks like the following:
