Java Imports Error -

-

i'm trying import org.apache.commons.fileupload.* being told not exist.

i downloading jar: http://commons.apache.org/fileupload/

and placing on classpath. doing wrong here?

most you're thinking of %classpath% environment variable. shouldn't that. jar file has go in /web-inf/lib folder of dynamic web application project. folder default covered webapp's classpath. bit decent ide (eclipse, netbeans, etc) automagically add build path whenever drop jar file in folder.

when you're compiling using plain vanilla javac.exe in command console, have specify in -cp argument.

update: assuming you're using windows , sitting in source root folder, here's how javac.exe should like:

javac -cp .;/path/to/tomcat/lib/*;/path/to/web-inf/lib/* com/example/servlet.java

note: wildcard works on jdk 1.6 or newer. otherwise you've specify libraries separately.
