TomEE
- Tomcat + Java EE
- Java EE 6 Certified
- young project: 1 year old (2011),
- focus on
- quality: testing
- performance
- low footprint (t1.micro linux image on amazon: 613 mb max)
- tight integration of component's (no extra downloads etc)
TomEE exists in 3 flavors
- basic web profile (+ JavaMail) - certified
- half of the JEE specs
- missing in official web profile
- corba, JAX-RPC
- JAX-RS, JAX-WS
- JMS, Connectors
- web profile + JAX-RS (new) - certified
- Plus: JAX-WS, Connectors & JMS - not certified
Integrates in Eclipse
- dynamic web project
- eclipse run as... run on server
- embedded Debug adapter
Modern JEE6 demo's with TomEE
- ejb:
- @javax.ejb.Singleton:
- @javax.ejb.EJB: inject
- @javax./jws.WebService -> automatic wsdl / publishing.
- @javax.ws.rs.... -> REST.
- CDI:
- bean.xml in WEB-INF
- pojo + @javax.inject.Inject
Testing & certifcation:
- very large TCK certification testsuite (+/- week)
- test infrastructure on Amazon EC2 to speed up certification process
Attention points when choosing plain Tomcat instead of TomEE:
- slower: lots of annotation scanning
- bloated memory from duplicate classes
- incomplete: OpenJPA, OpenWebBeans, JNDI
- no extensive tests from JEE TCK
TomEE+Arquillian
- arquillian
- testing framework
- junit based @RunWith("Arquillian")
- create & deploy small war with selected classes to test functionality
- distributed testing
- adapters included
- integrated debugging
Maven integration:
- tomee-maven-plugin
- configure servers
- start/stop servers
- deploy / undeploy
random TomEE stuff:
- Jelastic: Cloud provider with upcomming TomEE support.
- collects & reports multiple errors instead of stopping on the first problem
- META-INF/resources.xml + @Resource (without spring)
- config:
- tomee.xml:
- hybrid xml+properties config for readability (cfr apache httpd config)
- human readable durations
- or xml alternative: properties: conf/system.properties (can be mixed)
- tomee.xml:
