- All Implemented Interfaces:
- java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
public class AceWikiServlet
- extends nextapp.echo2.webcontainer.WebContainerServlet
This servlet class should be launched by the web server in order to start an AceWiki application. If you are using a
web application archive (WAR) then the web.xml file should contain something like this:
<servlet>
<servlet-name>GeoWiki</servlet-name>
<servlet-class>ch.uzh.ifi.attempto.acewiki.AceWikiServlet</servlet-class>
<init-param>
<param-name>ontology</param-name>
<param-value>geo</param-value>
</init-param>
<init-param>
<param-name>baseuri</param-name>
<param-value>http://attempto.ifi.uzh.ch/acewiki/</param-value>
</init-param>
<init-param>
<param-name>title</param-name>
<param-value>Geography Wiki</param-value>
</init-param>
<init-param>
<param-name>description</param-name>
<param-value>This wiki contains geographical knowledge.</param-value>
</init-param>
<init-param>
<param-name>login</param-name>
<param-value>no</param-value>
</init-param>
</servlet>
The parameter 'ontology' is mandatory and specifies the name of the ontology. This name is used in the URIs of the
OWL statements and for the file names on the server. The 'baseuri' parameter defines the base URI for the
OWL statements. The values of the parameters 'title' and 'description' are shown on the start page of the wiki. Finally,
the 'login' parameter defines whether users have to login before they can use the wiki. Note that the login feature
is implemented only very rudimentary.
Furthermore, SWI Prolog needs to be installed on the server and you need to have a compiled version of the Attempto APE
distribution. See the documentation of APELocal
for more information. The server has to know the command of your
SWI Prolog installation and the location of the ape.exe file. This is done by context parameters in the web.xml file:
<context-param>
<param-name>prologcommand</param-name>
<param-value>swipl</param-value>
</context-param>
<context-param>
<param-name>apecommand</param-name>
<param-value>/path/to/file/ape.exe</param-value>
</context-param>
One last tiny thing: The server delay window (that is shown on the client when the server is busy) looks for the
wait icon "../wait.gif". You should copy the file "src/ch/uzh/ifi/attempto/acewiki/core/gui/img/wait.gif" to the
respective folder on the server. (This should be improved, I admit.)
