Struts2 - File Tag (Form Tags)

In this section, we are going to describe the file tag. The file tag is a UI tag that renders an HTML file input element achieved through browsing.

Add the following code snippet into the struts.xml file.

struts.xml
<action name="fileTag">
  <result>/pages/uiTags/fileTag.jsp</result>
</action>

Create a jsp using the tag . It renders an HTML file input element.
The parameter name is used to set a name for element which we have used as name="uploadFile".

and the parameter accept is the HTML accept attribute that indicates the accepted file mime types which we have used as accept="text/*".

fileTag.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>

<html>
  <head>
  <title>File Tag Example!</title>
  </head>
  <body>
  <h1><span style="background-color: #FFFFcc">File Tag Example!
</span></h1>
  <b>File Name</b>
  <s:form>
  <s:file name="uploadFile" accept="text/*" />
  </s:form>
  </body>
</html>

Output of the fileTag.jsp


On clicking the "Browse.." button. You will see a window that can be used to browse a file to upload.
