File Tag (Form Tag) Example

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 <s:file>.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 theHTML 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.
