The mentioned package classes are not present in the compiletime classpath  Basically  Java has no idea what you re talking about when you say to import this and that  It can t find them in the classpath   It s part of Apache Commons FileUpload  Just download the JAR and drop it in  WEB-INF lib folder of the webapp project and this error should disappear  Don t forget to do the same for Apache Commons IO  that s where FileUpload depends on  otherwise you will get the same problem during runtime     Unrelated to the concrete problem  I see that you re using Tomcat 7  which is a Servlet 3 0 compatible container  Do you know that you can just use the new request getPart   method to obtain the uploaded file without the need for the whole Commons FileUpload stuff  Just add  MultipartConfig annotation to the servlet class so that you can use it  See also How to upload files to server using JSP Servlet

You could just add one needed external jar file to the project  Go to your project-- java build path-- libraries  add external JARS Then add your downloaded file from the formal website  My default name is commons-codec-1 10 jar
