[email] embed/include parsed JSP page file in email HTML body
I'm using Class HtmlEmail. Is there a way to embed a parsed JSP page in the
email message body. I use Tomcat and Java Server Pages. In my JSP pages I
can do something like: <%@ include file="ticket_email_response_body.jsp" %>
and want to be able to included this processed .jsp file in the body of the
text message.
I've looked at the examples in the documentation for embedding Files and
images and I've tried the following example code but it doesn't embedded the
actual parsed .jsp into the image. It includes the file as an attachment and
puts the text string of the quoted text in the body of the message:
File ticketEmailResponseBody = new
File("webapps/utrad/web/radtickets/ticket_email_response/ticket_email_response_dispatcher_page.jsp");
StringBuffer msg = new StringBuffer();
msg.append("<%@ include file=\"webapps/utrad/web/header.jsp\" %>");
msg.append("<%@ include
file=").append(email.embed(ticketEmailResponseBody)).append(" %><BR><BR>");
msg.append("+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+_+");
URL emailBodyURL = new URL("
http://192.168.1.2:8080/utrad/web/radtickets/ticket_email_response/ticket_email_response_dispatcher_page.jsp
");
String pid = email.embed(emailBodyURL,
"2nd_ticket_email_response_dispatcher_EMBEDDED_page.jsp");
msg.append("<BR><BR>try the above code again a different way:<BR> <%@
include file=\"" + pid + "\" %><BR>- Ferindo<BR><BR>");
email.setHtmlMsg(msg.toString());
email.send();
none of the "appends" I use above end up including the .jsp page as parsed
data in the body of the email/not even the raw unparsed text is included in
the message body. Looking at the logs, it looks like it's included the raw
text content of the JSP file (unparsed) but it doesn't include the text in
the body of the email, just the following:
<%@ include file="webapps/utrad/web/header.jsp" %><%@ include
file=ekzvyazwil %>
...and it included two of the .jsps in the message above as attachments
instead, not exactly what I was trying to do.

Hi,
It is indeed possible to generate HTML code from a JSP and send it as
an email. I've been doing it for a long time, however I tested the
code only on Tomcat 4.x and 5.x, beware that I don't know if it is
portable across other app servers. The basic idea is to wrap the
Response object to a new class, and get the email HTML code after
forward to the JSP page that generate it:
public class CapturedServletOutputStream extends ServletOutputStream {
/** The response buffer */
java.io.ByteArrayOutputStream buffer = new java.io.ByteArrayOutputStream();
/**
* Implement the only requried method.
* @param b An integer to write to the stream.
* @throws java.io.IOException Thrown if there is an exception
writing the message.
*/
public void write(int b) throws java.io.IOException {
buffer.write(b);
}
/**
* Gets the bytes from the contained buffer.
* @return The byte array captured.
*/
public byte[] getBytes() {
return buffer.toByteArray();
}
}
public class EmailResponseWrapper extends HttpServletResponseWrapper {
String contentType = null;
String characterEncoding = null;
CapturedServletOutputStream outputStream = null;
java.io.PrintWriter outputWriter = null;
/**
* Creates a new instance of EmailResponseWrapper
* @param response The response object to contain.
*/
public EmailResponseWrapper(javax.servlet.http.HttpServletResponse response) {
super(response);
outputStream = new CapturedServletOutputStream();
outputWriter = new java.io.PrintWriter(outputStream);
}
/**
* Gets a java.io.PrintWriter object for output.
* @return An implementation java.io.PrintWriter.
*/
public java.io.PrintWriter getWriter() {
return outputWriter;
}
/**
* Sets the content length of the response. This value is prevented
from being passed
* to the contained wrapper. It is discarded.
* @param param The content length.
*/
public void setContentLength(int param) {
}
/**
* Sets the content type of the response. This value is prevented
from being passed
* to the contained wrapper. It is recorded within this instance.
* @param str The content type.
*/
public void setContentType(String str) {
contentType = str;
}
/**
* Gets the content type from the member attribute.
* @return The content type of the response.
*/
public String getContentType() {
return contentType;
}
/**
* Gets the character encoding of the response from the internal
member attribute.
* @return The character encoding of the response.
*/
public String getCharacterEncoding() {
return characterEncoding;
}
/**
* Sets the character encoding of this response. This value is
prevented from being passed
* to the contained wrapper. It is recorded in a member attribute.
* @param str The content encoding.
*/
public void setCharacterEncoding(String str) {
characterEncoding = str;
}
/**
* Gets a servlet output stream.

return outputStream;

Use it this way:

EmailResponseWrapper(response);
rd.forward(request, responseWrapper);
// Generate Message
final Message message = new MimeMessage(session);
final String messageBody = responseWrapper.getOutput().trim();
message.setContent(messageBody, "text/html");

Hi Ricardo,
that was pretty much my understanding ... :-) ... as I mentioned before
in the commons-email trunk there is some new code which allows to pass a
HTML string and a base url to resolve the referenced images within the
HTML document. The images are than fetched from the server/filesystem
and added as embedded images (ImageHmtlEmail).

Re: [email] embed/include parsed JSP page file in email HTML body
Posted by Ricardo Duval <rd...@ibest.com.br>.
As far as I understand he wants the HTML content generated by JSP parsing.
Sorry, but I don't think that'll work because you don't have a servlet
engine running when you try to attach the JSP, so obviously the servlet
won't be generate and all you gonna have is the original JSP script. I
recommend using a template engine, like velocity or freemarker to generate
an HTML content as a String.

Hi Ferindo,
I'm not sure if I understand what you are doing ... :-)
What is a "parsed JSP page"? Recently there was some work on adding HTML
content and automatically adding embedding images.
