Problem
Doing some I/O works in Struts framework, but hits following exception in file upload process.
java.lang.NoClassDefFoundError: org/apache/commons/io/output/DeferredFileOutputStream
Where to download the Apache commons-io?
Solution
By default, Struts is using Apache “commons-io.jar” for its file upload process. To fix it, you have to include this library into your project dependency library folder.
1. Get Directly
Get “commons-io.jar” from official website – http://commons.apache.org/io/
2. Get From Maven
The prefer way is get the “commons-io.jar” from Maven repository
File : pom.xml
<dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>1.4</version> </dependency>

How do I install or include apache commons io in my version of my Java JDK which I’m running on Windows 7? I’m trying to run a java applet to read in a URL and save the contents, and its giving me an apache commons io error (which is not installed).
Thanks,
