This example is written in MySQL by using Struts's Formfile. . .
Use the user by selecting a picture, then press SUBMIT to deposit into the database
First set up a table:
Create Table Test (Name Varchar (20), Pic Blob); in MySQL Test Library
<% @ page language = "java"%> <% @ taglib uri = "http://jakarta.apache.org/struts/tags-bean" prefix = "bean"%> <% @ Taglib URI = "http: //jakarta.apache.org/struts/tags-html "prefix =" html "%>
jsp for multiform form </ title> </ head> <body> <html: form action = "/ multi" encType = "multipart / form-data"> must use encType = "multipart / form-data" to throw an exception file after committing, <html: file property = "file" /> <html: errors proty = "file" /> </br> Name: <html: text protety = "name" /> <html: errors proty = "name" /> </br> <HTML: Submit /> < HTML: Cancel /> </ html: form> </ body> </ html></p>
