Apache Tommee is Java EE6 web profile certified. (edit)

Apache Tommee is not a new product, but a bundle of Tomcat and Apache Java EE projects (OpenEJB, OpenJPA,...) by the Apache OpenEJB team. The lot is certified as a Java EE 6 Web Profile server.
Tommee is pretty lean (24Mb) and can run embedded.
The server bundles a set of components, all Apache gear: 

EJB	OpenEJB
CDI	OpenWebBeans
JSP/servlet	Tomcat
JSF	MyFaces
JPA	OpenJPA
JTA	Geronimo Transaction
JavaMail	Geronimo JavaMail

Version 1.0 of Tommee was released on april 30th 2012.

How to get Java EE6 libraries

If you want to download Java EE6 libraries, Oracle bundles the whole glassfish server, and more with the java EE6 SDK. Other application servers also bundle the libraries.
That’ a whole lot of bloat if you just want to compile a little webapp. You can just put a small subset of the glassfish jars in your classpath:

• glassfish_install_dir/glassfish/modules/javax.servlet.jar
• glassfish_install_dir/glassfish/modules/javax.servlet.jsp.jar
• glassfish_install_dir/glassfish/modules/javax.servlet.jsp.jstl.jar 
• glassfish_install_dir/glassfish/modules/jstl-impl.jar
• glassfish_install_dir/glassfish/modules/javax.ejb.jar (if using ejb)

If you are using maven this is not so much of a problem, just add a dependency to your POM.

<dependencies>
  <dependency>
    <groupId>javaee</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
  </dependency>
</dependencies>
<repository>
   <id>java.net</id>
   <name>GlassFish Maven Repository</name>
   <url>http://download.java.net/maven/2</url>
</repository>

Use artifactId javaee-web-api if you just want the web profile.
If you are not using maven, you can just download the jars from the maven repository:

• http://download.java.net/maven/2/javax/javaee-api/6.0/javaee-api-6.0.jar
• http://download.java.net/maven/2/javax/javaee-web-api/6.0/javaee-web-api-6.0.jar

For Java EE5 that is:

<dependency>
  <groupId>javaee</groupId>
  <artifactId>javaee-api</artifactId>
  <version>5</version>
  <scope>provided</scope>
</dependency>

• http://download.java.net/maven/1/javaee/jars/javaee-api-5.jar
