Alberto:
Maybe I'm missing something here but couldn't you simply
intercept the response output stream and redirect it to a file?
Have you tried using a filter?
Alternatively, ou may be able to do this by 'including'
your jsp from a servlet or another jsp.
One last thought. Tag libraries have the ability to intercept 'body content'
that appears between the corresponding opening and closing tags.
BodyContent body = getBodyContent();
String bodyOfCaptureTag = body.getString();
// write bodyOfCaptureTag to file here...
You could create a simple BodyTagSupport taglib object, use this tag in
a new jsp that you create that looks something like this.
<MyCaptureTag><jsp:include page="TheRealUrlGoesHere"/></MyCaptureTag>
This is a little bizarre, but should even work with Tomcat 3.1 .

Subject: Re: Info on customizing jspc - jasper
| Hi, and many thanks for the replies.
| Using <%@page extends="my.jsp.page.class" %> allows me to change only the
| name of the superclass for my JSP, but i need to do more than this.
| I need to change all the fixed lines of the generated code.
| For example, i would like to change:
|
| public void _jspService(HttpServletRequest request,
HttpServletResponse
| response)
| in
| public void _jspService(MyParam p1, String s, int n)
|
| or substituting
| JspFactory _jspxFactory = null;
| with
| String name = "X";
|
| and so on...
|
| The other solution proposed by Mike is good, but HttpServletResponse needs
a
| ServletOutputStream, and the generated servlet calls getPageContext()
which
| takes my request and response objects, so i guess my implementation will
not
| be so straightforward. Anyway, i think i'll try this way.
|
| If you have other ideas, please let me know
|
| Thanks
| Alberto
