Struts 2 File Upload & Save Example
Struts » on Nov 8, 2011 { 24 Comments } By Sivateja
Let us see how to work with file uploads in struts 2 frame work, things to remember while working with this type of application
- See in index.jsp i have taken <s:file name=”uploadFile” i mean my file tag name is uploadFile
- We used to write setters, getters for this property in Action class right, but while writing we need to write setters, getters for 2 more properties with names uploadFileFileName & uploadFileContentType
- I mean name format must be [ our file property name ]ContentType & [ our file property name ]FileName
- Actually at run time struts 2 container will injects the required file details into these properties, and thing is see struts.xml – line 23 fileUpload is the predefined interceptor class, this will take cares every thing
- Once file uploaded, struts 2 will stores the file with some temp name, its our responsibility to convert and save that file, see line numbers 39,40,41,42 in Action class of LogingEx.java
File Upload Example
required files….
- index.jsp
- success.jsp
- web.xml
- struts.xml
- LogingEx.java

Well I really enjoyed reading it. This article offered by you is very constructive for accurate planning.
thanks for this.
but if we want to check that only .txt or .csv is uploaded then how to validate the extension..
@Saharh
Actually in the current example i have given
<param name=”allowedTypes”>text/plain</param>
to allow text related files only. When the uploaded file type does not match one of the MIME types specified a field error will be created.
If that is image, you can give
<param name=”allowedTypes”>image/jpeg</param>
[or]
<param name=”allowedTypes”>image/gif</param>
its depends.

Hi Sivateja,
You explained very well but when i upload file (Content-Disposition: form-data; name="uploadedFile"; filename="downloadFile_7.pdf") then filename is not changing when i try to change filename using burpsuit.
I m trying to implement security for file name and content change.
