Send Template Email Using Struts2 View - struts2

Question

I am using Struts2, and I want to send the html output of one of my actions as an email.
In other words, instead of displaying the output html in the browser, I want to send it as an email.
I am using Apache Tiles to create my pages.
EDIT:
In general, can we get the the html result of struts view as a stream and pass it to another action?

Answer 1

First of all, I need to mention that using JSPs as email templates are not a good idea. But, if you need to do this, or you need to log the exact HTML that user sees (or any other reason), you can do this:
Create an interceptor for your action
Get the response from ServletActionContext
Wrap the response
Invoke the action
get (or even change) the response.
return the result.
This is part of my code:
import java.io.CharArrayWriter;
import java.io.PrintWriter;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletResponseWrapper;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.Interceptor;
//STEP 1
public class EmailInterceptor implements Interceptor {
#Override
public String intercept(ActionInvocation actionInvocation) throws Exception {
// STEP 2
HttpServletResponse response = ServletActionContext.getResponse();
PrintWriter out = response.getWriter();
// STEP 3
CharResponseWrapper responseWrapper = new CharResponseWrapper((HttpServletResponse) response);
ServletActionContext.setResponse(responseWrapper);
// STEP 4
String result = actionInvocation.invoke();
// STEP 5
String servletResponse = new String(responseWrapper.toString());
out.write(servletResponse + "whatever");
// STEP 6
return result;
}
public class CharResponseWrapper extends HttpServletResponseWrapper {
private CharArrayWriter output;
public String toString() {
return output.toString();
}
public CharResponseWrapper(HttpServletResponse response) {
super(response);
output = new CharArrayWriter();
}
public PrintWriter getWriter() {
return new PrintWriter(output);
}
}
}
