-Greenstone sets up Tomcat to run on port 8383 by default. To change this, you can edit the tomcat.port property in build.properties. If you do this before installing Greenstone, then running ’ant install’ will use the new port number. If you want to change it later on, shutdown tomcat, run ’ant configure’, then when you restart tomcat it will use the new port. +Greenstone sets up Tomcat to run on port 8383 by default.

 +If you are seeing lots of errors in packages/tomcat/logs/catalina.out like the following, then consider increasing the maximum size of the cache - edit the cacheMaxSize attribute on the Resources element in resources.tomcat/greenstone3.xml.in. 
 +<code>org.apache.catalina.webresources.Cache.getResource Unable to add the resource at [... class name ...]

 + 
 +==== Using Greenstone inside a frame ==== 
 + 
 +Greenstone's cookies are SameSite=none by default (prior to April 2024) or after that, SameSite=strict. Browsers nowadays handle samesite=none in different ways. To get Greenstone to work properly inside a frame, the cookies need to be SameSite=none, partitioned=true. This needs a later version of Tomcat. 
 +From April 2024, we use a newer version of Tomcat (8.5.99) instead of 8.5.51. This has the ability to set partitioned for cookies.  
 +This feature is available in Greenstone 3.12 and later. 
 +Edit resources/tomcat/greenstone3.xml.in - comment out the CookieProcessor line setting strict, and uncomment the one setting none + partitioned. Then restart Tomcat 
 +<code> 
 +<!-- if greenstone is to be run in an iframe, need to use the --> 
 +<!-- sameSiteCookies=none version of the CookieProcessor --> 
 +  <CookieProcessor sameSiteCookies="none" partitioned="true"/> 
 +  <!--<CookieProcessor sameSiteCookies="strict"/>--> 
 +</code> 
 + 
 +==== Turn off localhost access logs ==== 
 + 
 +By default, one of the enabled forms of logging in Apache Tomcat is the Local Host Access Log.  This log tracks every connection made to the server. This can add up to a lot of logs that can quickly overwhelm the hard drive space of your server.  
 + 
 +To disable this, edit resources/tomcat/server_tomcat8.xml.in 
 + 
 +Look for the ''<Valve className="org.apache.catalina.valves.AccessLogValve".../>'' section and comment it out by surrounding it in ''<nowiki><!--  --></nowiki>''
