Apache FileUpload - what version of Tomcat can run it?

Question

Hi. I'm trying to use the Apache Commons FileUpload component (http://commons.apache.org/fileupload). It works fine on my local PC (Java 1.5.0_15) but fails on the Unix server running Tomcat 4.1.29 and Java 1.4.2_12-b03. I've got the latest version of the upload component in the WEB-INF/lib folder. It throws this error (included only the top section; there are more, similar errors having to do with each fileupload component call). Do I need an older version of the upload component to work with this version of Tomcat and Java? If so, which version do I need to download? The oldest I could find dated to 2003. Thanks.
The server encountered an internal error () that prevented it from fulfilling this request.

Apache FileUpload - what version of Tomcat can run it?First of all, why don't you ask Apache specific questions at the Apache mailinglist?
Regarding to your actual problem: those are just ordinary compilation errors which are complaining that the mentioned packages and classes aren't available in the classpath. The solution is obvious: add the mentioned packages and classes (or in this case, the JAR file(s) with it) to the classpath during compile time and you're fine.
