Userful, but some important missing details,
January 16, 2009 at 7:06 AM

Thanks. The tutorial was very useful and I had a basic file upload up and running in no time.

One very important piece of missing information however: you need to include the commons-filupload-1.2.jar and commons-io.1.3.1.jar files otherwise it won't work. This will fix the issue that people are having with "Unable to load bean org.apache.struts2.dispatcher.multipart.MultiPartRequest" errors.

Other useful items. In order to change where the files get downloaded to, add a line to your struts.properties file. For example:

struts.multipart.saveDir=/tmp/uploader

Finally, the file is deleted once the operation finished. In order to store it add some code to the "execute" method. For example:

public String execute() throws Exception {

File outFile = new File("/tmp/newfilename");
InputStream inStrm = new FileInputStream(getUpload());
OutputStream outStrm = new FileOutputStream(outFile);

// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = inStrm.read(buf)) > 0) {
outStrm.write(buf, 0, len);
}
inStrm.close();
outStrm.close();

return SUCCESS;
}
