Image and Binary File Conversion

DWR 3.0 features a new FileConverter that handles the following binary files:

  • Images (any child of java.awt.BufferedImage)
  • InputStreams (any child of java.io.InputStream)
  • FileTransfer objects (org.directwebremoting.io.FileTransfer)

In order for upload to work, commons-fileupload and commons-io are required on the classpath. See the commons-upload dependency chart for more information. DWR will give you the error message: "file uploads not supported" if this JAR file is missing.

The DWR war file contains a number of examples of generating PDF files, as well as uploading and downloading images. Full source and explanations are included with these examples.
