The application uses the work directory to store data and configuration files.

For example, the filestorage subdirectory of the work directory is used by the file storage. In addition, the Middleware block saves generated persistence.xml and orm.xml files in the work directory on start.

Work directory location is determined by the cuba.dataDir application property. For the Middleware, Web Client and Web Portal blocks in fast deployment configuration in Tomcat, it is a subdirectory with the name of the web application in the tomcat/work directory.
