upload file in struts2 using ajax

Question

How can I upload a file in struts 2 using ajax

Answer 1

If you want to return json data to client, you can get the error that a file download dialog appear to download json as a text file. I use struts2-json plugin so to fix this error, just add the following config to your action in struts.xml

text/plain

my sample

        
            
            /WEB-INF/pages/uploadForm.jsp
            
                 
                         fileStoreManager, file
                 
                 text/plain
            
            mainMenu
