Nuxeo will be moved to Tomcat 7 when there is customer demand, or if we have some free time…

EDIT Tomcat 7 is supported since Nuxeo 5.7.2, see NXP-10071.

Ok, so I finally had some time and managed to get Nuxeo 5.5 running in Tomcat 7 so, for reference, this is what I had to do:

• Start with clean Apache Tomcat 7.0.27 and just use meld or some directory diff tool to do the following:

• Add nuxeoctl, nuxeo-lanucher.jar, etc .. to bin

• Add endorsed libs

• Add missing jars to lib

• Add nxserver directory

• Setup the templates (templates/default/conf) diff from nuxeo 5.5:

  • server.xml / server.xml.nx

    Remove:

    <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />

    Add :

    <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" /> <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

• Changes to nuxeo-launcher.jar (just clone nuxeo-distribution and change):

• nuxeo-distribution/nuxeo-launcher/src/main/java/org/nuxeo/launcher/NuxeoTomcatLauncher.java

      protected String getClassPath() {
          String cp = ".";
          // This is not needed - cp = addToClassPath(cp, "nxserver" + File.separator + "lib");
          cp = addToClassPath(cp, "bin" + File.separator + "bootstrap.jar");
          cp = addToClassPath(cp, "bin" + File.separator + "tomcat-juli.jar"); // Add tomcat-juli.jar
          return cp;
      }
  

• Changes to nuxeo-runtime-tomcat-adapter.jar (just clone nuxeo-runtime and change):

  • nuxeo-runtime/nuxeo-runtime-tomcat-adapter/src/main/java/org/nuxeo/runtime/tomcat/NuxeoLauncher.java

    protected void handleEvent(NuxeoWebappLoader loader, LifecycleEvent event) {

        ...
        // Was Lifecycle.START but should probably be Lifecycle.CONFIGURE_START in Tomcat 7 
        // hardcoded just for testing!
        if (type == "configure_start") { 
        ...
        }
    

    } `

UPDATE

After properly changing the Lifecycle event to “configure_start” most of my previous changes are not needed and in fact break the classloading. I've updated the answer to match the proper changes to make.
