Upload multiple files using single browse button in Struts2

This tutorial shows how to upload multiple files using single browse button in Struts2. There is another tutorial on Multiple Files Upload in Struts2 which uses multiple browse buttons for multiple file upload but this tutorial uses only one button for uploading multiple file upload in Struts2. We need to use just attribute multiple=”multiple” with <s:file/> tag for uploading multiple files using the single browse button.

I won’t explain much details in this tutorial but if you need more explaination then you can go through another tutorial Multiple Files Upload in Struts2.

Single file upload example in struts 2

File Upload is one of the common tasks of a web application and Struts 2 provides built-in feature for single file upload through FileUploadInterceptor. Interceptors are cross cutting concerns or common concerns like Logging; for more information on Interceptors please refer to Interceptors in struts2

FileUploadInterceptor(for more information go to File Upload Interceptors) is configured in the struts-default package that we usually extend in Struts 2 package configuration. FileUploadInterceptor also provide options to set the maximum file size limit, allowed file types and extensions that can be uploaded to the server. Struts 2 provide option to configure the maximum file size limit through struts.multipart.maxSize variable. This comes handy to set the limit to upload files incase of multiple files uploading in a single request. Continue reading “Single file upload example in struts 2”

File upload example in JSF 2

Here we will see file upload example in jsf 2. The file upload implementation in Java based web application is very complex and we need to be dependent on Apache fileupload libraries. When we work on JSF(Java Server Faces), we have jsf pages with other inputs along with file inputs, so integration with Apache fileupload libraries make more complex or else we have to dependent on some third party file upload components like primefaces, richfaces etc.

Servlet 3.0 is part of Java EE 6 specification, hence “Part” interface and @MultiPartConfig annotation were introduced for easy way to do the file upload without any third party libraries. So any servlet 3.0 implementation servers like Tomcat 7.x, Jboss 6.x, GlassFish 3.x can get benefit of servlet 3.0 but the file upload feature is not available in JSF 2.1 and again we have to be dependent on servlet to do the file upload in JSF.
