I've now upgraded to Dazzle servlet to work with the Servlet
API version 2.2 -- previous versions used 2.1, but this now
seems to be dead.  It should also work with 2.3 containers,
once they start to appear.

For people looking for a  Servlet 2.2 container, the leading
open source product seems to be Tomcat (http://jakarta.apache.org/).
I've been testing with Tomcat 3.2beta7, and this seems to work

One of the advantages of servlet 2.2 containers is that they
support a standard servlet deployment mechanisms.  I've prepared
a `quick test' release of Dazzle, based on the configuration I've
been using for some of my own testing.  You can download this


This contains the servlet itself, the libraries it required
(BioJava and Xerces-J), some test data, and a deployment
descriptor file, all wrapped up in the Servlet 2.2 `Web application'

To try it out:

  - Install a servlet 2.2 container (tomcat)

  - Download the test distribution and rename it to `das.war'

  - Drop das.war into the deployment directory of the container
    (The standard Tomcat distribution has a `webapps' directory).

  - Restart the servlet container

  - Test by pointing your web browser to:
    This should give an HTML `welcome' page generated by the

Let me know how this works out -- I'd be especially interested
if anyone was testing using a container other than Tomcat.

In the meantime, I'm still working on the bridge which will
allow us to serve EnsEMBL -- watch this space.
