The article shows how we can achieve authentication across the application with the use of custom interceptors and make our code loosely coupled and achieve flexibility with code reuse. Struts2 token interceptor We can use Struts2 token and tokenSession interceptors to handle multiple form submission problem at server side in the web application.
This article explains about these interceptors in detail with a working example. Struts2 execAndWait interceptor We can use Struts2 execAndWait interceptor to return an intermediate response page to client incase of long running action classes.
Once the action class execution is finished, the final response is returned to the client. This article explains about execAndWait interceptor and how can we use this for long running action classes. The article provide details about the usage of OGNL expressions and how we can create our own type converter classes.

Struts2 Control Tags Struts2 control tags are used for manipulation and navigation of data from a collection.
This article provide details about the Struts2 control tags and how we can use them for conditional flow and iterate over an array or collection. We also learn about some other control tags used to sort list, merge lists, append lists and take subset of list with example project.

UI tags are also responsible for binding form properties to action class properties. This article provide details about mostly used UI tags with example project.

Regards, Arun. Can you please let me know how can I get actual selected file path on client machine.
For e. Hello All My application implemented with two clients swing and struts2 In swing client - when user click on pdf button it opens File chooser using JFileChooser- user select file [e. Same way I want to implement it in my struts2 web client. My problem in web client is not able to get user selected file path e.
I'm not sure why you are having problem with this. User clicks on pdf button, the request goes to the server, the server sends the pdf file as an attachment, the browser asks the user where to save the file, the user selects a location and the download starts on the location.

Why do you need to send the location to the server?? The server will just send the file and the user will then select the location to save the file.
Example on how to force browser to save the pdf file can be found here it simply uses the content-disposition header that I pointed out before , the page actually uses a JSP to do all the scripting code which is not very good, but the logic is correct Ok, If file is too large, do you think is it fessaible to write contenet into ServletOutputStream if not can you let me know alternative soluation.
There is no alternative.
It doesn't matter what the size of your file is, if its a binary file, you'll have to use ServletOutputStream, if its a text file, you can use PrintWriter Pradeep Adibatla. I have a binary file a png and i used Fileoutputstream instead of ServletoutputStream.
Will it make a difference? Always look on the bright side of life.There are more articles to come in Struts 2 tutorial series, do bookmark this post for future reference. Newer Post Older Post Home.
