The webopi.war is basically a complete copy of CSS BOY that runs inside tomcat.
It's somewhat convenient to set up because it uses the same *.opi files as the CSS desktop version.
But it's also terribly inefficient:
Every web client starts a copy of CSS inside tomcat.
Development of this approach has halted.
A better way forward is a separate, web-specific implementation like WebEPICS presented at the last two EPICS meetings, which also reads *.opi files but handles them in a more efficient way.
Anyway, to setup the webopi, you don't need CSS at all.
What you do need is:
Copy the webopi.war into the tomcat webapps folder.
In tomcat/conf/catalina.properties, add a line
When you then start tomcat, you should find that it unpacks the webapps/webopi.war into a webapps/webopi directory.
When you then point a web browser to http://that_host:8080/webopi, you should see the display defined in org.csstudio.opibuilderstartup_opi.
If you get the "No connection to host.." error message that you emailed, you didn't start tomcat, or you started it on a port other than 8080, or you have a firewall blocking access to it.
