Sakai runs in Tomcat 7

Good news, everyone! Sakai runs in Tomcat 7. And no modifications to Sakai are required.

As of Tomcat 6, the old common/lib, server/lib and shared/lib have been collapsed into one /lib directory. However it’s possible to restore that old layout so that applications can run in the newer servlet containers without having to be updated themselves.

Heres what you need to do:

  1. Build and deploy Sakai into a Tomcat 7 install.
  2. Open the Tomcat 7 conf/catalina.properties file.
  3. Find the line that starts with common.loader= and append to the end:
    ,${catalina.base}/common/lib/*.jar
    That is, we’ve appended the old classloader location for the common jars to the end. Make sure you only append and not replace, you need to keep the existing configuration.
  4. Find the line that starts with server.loader= and replace it with:
    server.loader=${catalina.base}/server/lib/*.jar
    That is, we’ve restored the old classloader location for the server jars.
  5. Find the line that starts with shared.loader= and replace it with:
    shared.loader=${catalina.base}/shared/classes,${catalina.base}/shared/lib/*.jar
    That is, we’ve restored the old classloader location for the shared jars.
  6. Save and close.
  7. Start Tomcat.
  8. Enjoy!

  1. Great work Steve, thanks for sharing this! I take it there hasn’t been a lot of QA work done on this configuration yet? It would be really great to see Sakai under Tomcat 6 or 7 tested thoroughly so that we could feel safer upgrading.

    Jez

    • Hi Jez, no formal QA as yet, AFAIK this is the first ever test of Sakai and Tomcat 7 that’s been performed. Apparently some JSF tools don’t work very well (ahh JSF) but a JSF upgrade that is being performed may fix that. We’ll need to dig deeper. Still, it’s promising that the bulk of Sakai works fine.

  2. An update, the following tools do not startup. And surprise surprise, they are based on our old friend JSF:

    • Gradebook
    • Post Em
    • Section Info
    • Roster

    these all fail with a generic (and useless):
    org.sakaiproject.portal.api.PortalHandlerException: java.lang.IllegalArgumentException: Unable to find registered context for tool with ID sakai.site.roster
    at org.sakaiproject.portal.charon.SkinnableCharonPortal.doGet(SkinnableCharonPortal.java:878)
    caused by: java.lang.IllegalArgumentException: Unable to find registered context for tool with ID sakai.site.roster

    Samigo also fails but it’s stacktrace is more promising which may mean a fix is easier to pursue:

    • Another update to the JSF issue. Adding commons-el.jar to shared/lib resolves the issues with the above tools.

      I noticed a DAV issue on startup, will resolve that next. So far, so good. No code mods!

    • Hi Tushar,

      Not yet, but the DAV module is being re-engineered as a Google Summer of Code project so hopefully within a few months there will be a better DAV implementation that will work in TC7.

      cheers,
      Steve

      • tushar says:

        Hey Steve,

        Thanks for the reply !

        Can you also throw some light onto what is the significance of DAV in Sakai ?

        Regards,
        Tushar

      • DAV is the WebDAV module that allows you to mount a Sakai site as a network resource and access the files in Resource, like from within Windows Explorer, Mac OS Finder, Cyberduck etc.

  3. Heres the dav error:
