Re: sending a JSP page by email
Hi,
Thanks for the response. This is really a neat solution of my problem
, since I can use Tomcat's JSP engine to create dynamic emails.
I copied the solution you posted on your blog. The email is sent OK
but, since a use a model 2 web framework like Struts, I send the
email, and then I need to send the HTML response back to the client
browser, but when I call the forward(request, response) method, I get
the typical
java.lang.IllegalStateException: Cannot forward after response has
been committed
exception.
I tried overriding the method boolean isCommited() { return false;} in
the class EmailResponseWrapper but it doesn't work either.
Did you ran into the same problem that I did too?
Thanks in advance,
Gabriel

Hey kids,
I had run into this a while back.
I've got a link here to what I did. It's rough and ready so don't expect
too much out of it, but it should be enough to get you runnning.

I *believe*, but don't hold me to it, that you can implement a filter AFTER
the JSP renders, in the latest servlet spec. With that, you shouldn't have
much trouble taking the output stream and sending it as an eMail. I'd also
assume, although I don't know for sure, that you could basically kill the
response at that point, so it's not trying to send back to the client or
anything.

I will be happy if you let me know if it works.
The basic Idea is that if we used a servelet we had no problem taking the
StringBuffer created and coping it into the mail message and not back to
the
browser.
The problem with JSP, it's actually a servlet but we can not control it.
In the Java Server Page (O'reilly page 315) book I found some directive
element.
%@ page buffer=12kb autoFlash=false %
When autoFlash=false the JSP container will not flush the buffer until
the
following script % out.flash() % is used. Maybe there is a way to
redirect
this output writer to a buffer and email it.
What do you think?

Subject: sending a JSP page by email
Hi,
How can I take advantage of Tomcat's JSP processing engine to use a
JSP page as a template for an email?
That is, I want to do something like a page forwarding from a servlet,
but this forwarding process the JSP page and, instead of send it to
the browser, it send it by email to somebody.
Thanks in advance,
Gabriel

Re: sending a JSP page by email
Here is what I use:
// here is a function from my MailUtils class
public boolean formSend(String to, String fromAddress, String
fromPersonal,
String msgSubject, PageContext pc, String templateURL) {
if (templateURL == null || templateURL.equals()) { return
formSend(to,
msgSubject, pc); }
String httpHost = pc.getRequest().getServerName();
Enumeration params = pc.getRequest().getParameterNames();
String queryString = ?;
if (templateURL.indexOf(?) = 0) queryString = ;
while (params.hasMoreElements()) {
String param = (String) params.nextElement();
try {
queryString += param
+ =
+
URLEncoder.encode(StringUtils.encodeHTML(JSPUtils.getParam(pc,
param)),
UTF-8) + ;
} catch (Exception e) {
e.printStackTrace();
}
}
String url = http://; + httpHost + templateURL + queryString;
try {
// see the Webpage object
Webpage wp = new Webpage(url);
String msgBody = wp.loadPage();
// replace it your own send mail function
send(to, fromAddress, fromPersonal, msgSubject,
msgBody, true);
} catch (Exception e) {
e.printStackTrace();
return false;
}
return true;
}
// Here is the Webpage
package com.edunet.iwas.util;
import java.net.*;
import java.io.*;
public class Webpage {
private static final String NEW_LINE =
System.getProperty(line.separator);
private String content;
private URL u;
public Webpage(String urlString) throws MalformedURLException {
urlString = StringUtils.replace(urlString, , %20);
this.u = new URL(urlString);
}
public String loadPage() throws IOException {
BufferedReader in = new BufferedReader(
new InputStreamReader(u.openStream()));
String temp;
content = ;
while ((temp = in.readLine()) != null)
content += temp + NEW_LINE;
/* you don't really need the NEW_LINE */
in.close();
return content;
}
public String getContent() {
return content;
}
}
Please use it at your own risk...
