Getting result of JSP before sending to client

[Steven Yang]

Hi

I am wondering is there a way in Struts2 to get the result of JSP before
returning the composed HTML back to client?

for example

public String execute() {
   ...do my logic and prepare my data

  ...then using the data, compose a HTML file from existing jsp

... then i need to save the HTML file somewhere

...then
return SUCCESS; --> maybe to same HTML or other JSP
}

Thanks

you can use the embeddedjsp plugin to process a jsp as a template
library without using the container. another alternative is to create
your own filter and create a response object which will have a writer
to capture what is written to it, so you can modify it and then write
it to the real output stream.  Can you tell us what you are trying to
do? maybe you don't need a jsp and could use freemarker or velocity.

i will take a look at embeddedjsp plugin

actually what we are doing is
we have a form/survey and after user completes it, we, originally, want to
save it as PDF which would have no problem for me, but due the time
constraint we decided to simply save the file/report as HTML, thats why i
want to know whats the simplest way to do it.
The saved HTML may or may not look exactly the same as the page we return to
the user, i am not sure yet.

thanks

hi i just looked at embeddedjsp plugin
it requires JAVA 1.6 which i am not using, only using 1.5.

i also need to make sure saving the HTML is in the same Transaction(database
transaction) as saving the record. Therefore, intercepting the result in
filter may not be a solution for me.

is there other way?

Thanks
