The root of the tomcat installation is referred to as "${catalina.home}" and will be used from here. The root of a tomcat installation can be recognized by the webapps and conf directories.
It is recommended to give a tomcat a heapsize of at least 1GByte, but preferably more. This can be done using the -Xmx1024m java argument. Since 2019.02 the FEWS Web Services won't start if there is not enough memory available. For general instructions on installing tomcat, see also: Delft-FEWS Installation - Install Apache Tomcat.

FewsWebServices.war installation
The FEWS Web Services are packaged in a file called the FewsWebServices.war. Before installation, make sure the tomcat server has been shutdown. Inspect the ${catalina.home}/webapps folder and inspect if there is a FewsWebServices folder. If this folder exists, delete the ${catalina.home}/webapps/FewsWebServices folder. The FewsWebServices.war file has to be copied to the ${catalina.home}/webapps folder.
Web Services log files
After upgrading the FewsWebServices.war, old log files have to be deleted. The log files are stored in: ${catalina.home}/fews/Region_Home folder. All *.txt files should be deleted.
