By default Pentaho Business Analytics contains a packaged “mini” tomcat which starts Pentaho on port 8080, this maybe an issue ( BIND ) if we have another web applications running over this port. To change this port we need to modify the following files.
<!-- FullyQualifiedServerUrl is used only in the case of offline content generation and whenever something need to talk back to the server --> <context-param> <param-name>fully-qualified-server-url</param-name> <param-value>http://localhost:8787/pentaho/</param-value> </context-param>
<Connector URIEncoding="UTF-8" port="8787" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /,>
Remember to restart BI Server and it is always a good idea to clear logs, temp and catalina localhost temp files.
