If you use IIS as web server and Tomcat as Servlet engine then you may want to install the ISAPI Redirector.
The regarding files for Apache Connector can be found on the WebOffice10R3-DVD:
WebOffice10R3-DVD\Software\Miscellaneous\Apache Tomcat Connectors\Apache_Tomcat_Connectors.zip
Note: This is not a full version of Apache Tomcat Connectors but a modified package to use in combination with SynerGIS WebOffice 10 R3!
Detailed information is provided on the website of Apache Tomcat:
http://tomcat.apache.org/download-connectors.cgi
There are two options how to install. If you are already using Tomcat and have customized the files "uriworkermap.properties", "web.xml", "context.xml" or "workers.properties.minimal" use Option A. If you did not customize your Tomcat installation you can use the faster Option B.
