How is the implementation of WebWork download, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

When WebWork downloads the file, first add the following to the xwork.xml:

Application/octet-stream inputStream attachment;filename= "${downloadFileName}" 4096 application/octet-stream inputStream attachment;filename= "${downloadFileName}" 4096

At this point, you need to pass fileName as an argument. Here is action:

Import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.InputStream; import java.io.UnsupportedEncodingException; import com.opensymphony.xwork.Action; public class FileDownloadAction implements Action {private String fileName = ""; public InputStream getInputStream () throws Exception {InputStream is = null; try {is = new FileInputStream (fileName) } catch (FileNotFoundException E1) {} return is;} public String execute () throws Exception {return SUCCESS;} public void setFileName (String fileName) {this.fileName = fileName;} public String getFileName () {return fileName } public String getDownloadFileName () {String downFileName = fileName; try {downFileName = new String (downFileName.getBytes (), "utf8");} catch (UnsupportedEncodingException e) {e.printStackTrace ();} return downFileName;}}

This completes the WebWork download.
