Saving an HTML file generated by the JSP on the Server - Possible?

[Desai Sandeep]

Hi,
How do I save the HTML file generated by the JSP on the server.I want to save the file and send it as an attachment to the mail.
Is it possible to write some code in JSP which does this.
Thanks in advance,

One way to do this is to use URL.getContent() to generate a request to the JSP and capture the generated content in a String. Not terribly efficient, but easy and for most purposes it will do fine.

Peter,
Could you elaborate on this.If possible please paste a code for this.

Just off the top of my head, so it's guaranteed not to work:

URL url = new URL("http://localhost/location/of/your.jsp");
String content = url.getContent().toString();

Good luck

Hi Peter,
I have doing some research on this for sometime now.I had received some suggestions that it can done using one of the three methods.

1. Filtering added in Servlet 2.3 specification
   
2. Custom tag implementing the BodyTag interface
   
3. URLConnection
   

The third solution is what probably you have mentioned.Does this mean using Serialization and writing it to a file using the ObjectOutputStream, and then reading it when required using the ObjectInputStream.
About the first 2 methods, I still have no clue.Any advise on this would be highly appreciated.
Thanks in advance.
Regards,

[prabhat kumar]

it is very easy to get the html content generated by the servlet ..
one way is to as below ..
try
{
URL u = new URL(strUrl);
InputStream i = u.openStream();
//now u have the inputstream ..u can do anything ..like writing to the file
}
catch(Exception e){}
hope it might help

Hi Prabhat,
That is right!!I guess to do it using URLConnection is one of the ways to do it.
However, I also wanted to explore the other possible methods :

• Filtering added in Servlet 2.3 specification
  
• Custom tag implementing the BodyTag interface
  

Any ideas on this?
Thanks in advance,

To start with your last remark, yes, that's what I suggested (as the javadoc points out, URL.getContent() is just shorthand for URL.openConnection().getContent()). But serialization -- you want to capture a JSP's HTML output, right? So it's just plain text. Object serialization doesn't enter the picture as far as I can see.
About the other two solutions, not quite sure. Filtering is quite new and your server may not support it, also it's not clear to me how it would help.
Tag libraries are well supported, but wouldn't that mean embedding your HTML e-mail as part of the JSP? I silently assumed that you wanted your e-mail to be a separate, easily updateable template. Taglibs would be more efficient though.

Hi Peter,
That is correct
I donot need to Object Serialization, since it is in plain text HTML format.

That is right.My HTML email would be a part of the JSp, if I use the Taglibs.But since, my primary aim was send information through email, and I didnot know about this solution (I am still not sure how to do it ), I thought saving it and then sending would be a better option.
Thank you for your views.
