The  application frevvo.war now runs directly from the war file. This means that frevvo.war no longer expands its contents into <frevvo-home>\tomcat\temp or <frevvo-home>\tomcat\webapps\frevvo.Tomcat still does create a temp folder, for example <frevvo-home>\tomcat\temp\0-frevvo (the actual folder depends on where java.io.tmpdir is pointing to) to store form/flow cached htmle and other temporary files.
