Hi, I have installed jakarta-tomcat-4.0-20010717 onto an NT machine. 1) Web Folders =========== Is there some basic incompatibility between TOMCAT WebDav and Microsoft Web Folders? I can open a web folder on http://localhost:8080/webdav and I can create collections using the new folder option. But when I try to copy resources (using cut and paste), I keep getting an error: "An error occurred copying some or all of selected files." This is the output from localhost_access_log.xxxxxx.txt: "HEAD /webdav/test/test.txt HTTP/1.1" 404 243 "PUT /webdav/test/test.txt HTTP/1.1" 201 239 "HEAD /webdav/test/tsts.txt HTTP/1.1" 200 - "PUT /webdav/test/test.txt HTTP/1.1" 409 255 "PUT /webdav/test/test.txt HTTP/1.1" 409 255 I note that SkunkDav merely performs a single PUT to upload a file into a WebDav collection. 2) Relational Database ================ Do I need a relational database to use TOMCAT? thanks Russell Thamm
