J2EESupport

Revision 7 as of 2008-05-28 21:16:11

Clear message

Issues to discuss at Server Team meeting

  • Best technical target : modular, servlet container, monolithic J2EE ?
  • Maven (needed to build all modular targets : Geronimo and GlassfishV3) : is it possible to make it compatible with Debian package building in Intrepid timeframe ?

  • Targeting Main inclusion would push lots of packages (javalibs/mavenplugins...) in Main

Ubuntu server J2EE support options

Tomcat 6

Type :

Servlet container

License :

Apache License v 2.0

Builds from source :

Yes, with openjdk (not with gcj -- missing J2SE 1.5 Socket.setPerformancePreferences methods)

Packaged :

No. Need to workaround Ant download

Maintainability :

good

Compatibility :

Servlet/JSP : 2.5/2.1

Current version :

6.0.16

Link :

http://tomcat.apache.org/

Notes :

  • Tomcat is downstream of Glassfish.
  • Lost contributers from Sun.

Tomcat 5.5

Type :

Servlet container

License :

Apache License v 2.0

Builds from source :

Yes

Packaged :

yes (5.5.25 in Universe)

Maintainability :

good

Compatibility :

Servlet/JSP 2.4/2.0

Current version :

5.5.26

Link :

http://tomcat.apache.org/

Current package problems :

  • dependency on JRE (java2-runtime), should be on JDK (java2-compiler) (LP: #179447, #112626)
  • file permissions incompatible with admin interface (LP: #234127, #220871)
  • incompatibility with openjdk (LP: #229404, #212521)
  • 5.5.26 needed to fix CVE-2007-5333 (LP: #220540, #228665)

Additional packages needed in main to build :

  • libcommons-daemon-java
  • libcommons-digester-java
  • libcommons-el-java
  • libcommons-fileupload-java
  • libcommons-httpclient-java
  • libcommons-launcher-java
  • libcommons-modeler-java
  • libstruts1.2-java

Geronimo

Type :

Modular (Servlet container or J2EE application server, uses Tomcat or Jetty)

License :

Apache License v 2.0

Builds from source :

Yes (with OpenJDK + patch from Geronimo)

Packaged :

No. Uses Maven.

Maintainability :

fair

Compatibility :

J2EE v5 since Geronimo 2.0.1

Current version :

2.1.1

Link :

http://geronimo.apache.org/

Notes :

  • "release often" (every 2-4 months)
  • Right featureset/Ubuntu-style management options
  • Modular design. Technologically on par with JBoss and Glassfish v+1.
  • Good upstream maintenance relationship.

Running Geronimo :

Building Geronimo :

  • Should be built as modular packages with a few metapackages (geronimo-miniG-tomcat, geronimo-J2EE-tomcat...)
  • Maven-based build process pulls lots of deps in ~/.m2 -> difficulty to debianize

  • Very (really) slow using gcj - aborted
  • Fails to build using openjdk-6-jdk :
    • even if overriding JDK version check in build.xml
    • org.apache.geronimo.axis2.pojo.POJOWebServiceContext is not abstract and does not override abstract method <T>getEndpointReference(java.lang.Class<T>,org.w3c.dom.Element...) in javax.xml.ws.WebServiceContext

    • JDK 1.6 incompatibility (new getEndpointReference abstract method in jax-ws)
    • Build instructions require Sun's JDK 1.5.
  • Geronimo team provided patch to build under 1.6 @ https://issues.apache.org/jira/browse/GERONIMO-4089

    • Very reactive help on FreeNode #geronimo, by Kevan Miller (kevan) and Jarek Gawor (jgawor)

    • Builds with MAVEN_OPTS="-Xmx768m -XX:MaxPermSize=256m" in ~/.mavenrc

    • Tests at the end of the build fail with loader constraint violation error : http://pastebin.ca/1032462
