[opencms-dev] OpenCMS Access

Hello Markus,

we use the following code to trigger the template mechanism in OpenCms. In the example, myEmail.html is a resource of type XmlPage with a template assigned.

CmsObject cms=...;
HttpServletRequest request=...;
HttpServletResponse response=new DummyResponse();
CmsResource resource=cms.readResource("/myEmail.html");

I_CmsResourceLoader loader = OpenCms.getResourceManager().getLoader(resource);	    
cms.getRequestContext().setUri(cms.getSitePath(resource));
	    	    
byte[]result= loader.export(cms,resource,request,response);

public class DummyResponse implements HttpServletResponse {

    public ServletOutputStream getOutputStream() throws IOException {

	return new ServletOutputStream(){

	    public void write(int b) throws IOException {
		// Do nothing
		
	    }
	    public void write(byte[] b) throws IOException {
		//Do nothing
		
	    }
	    public void flush() throws IOException {
		//Do nothing
		
	    }    

	};
    }

   // ... Rest of the implemented methods of HttpServletResponse
}


The reason why response is of type DummyResponse, is because in the process of exporting, OpenCms tries to write to it. It can also be useful if in you don't have access to a real HttpServletRequest at all. Then you should use a kind of dummy HttpServletRequest. 

This is working, but the problem is that it is completely dependent of the use of the response that the OpenCms implementation does, so I will be very glad to know if there is a more elegant approach.

Kind regards,

Hello Bernd,

Thats exactly what I would like to do. The OpenCMS API call would my favourite. Could you just point me to the right Class?

Markus

Hi Markus,

so what you like to implement is to have the structured content generated as usual but nor for the browser client but on the server itself to be able to send it via email?
One way would be to export the structured content and then use the generates file for whatever purpose.
But I think there may be also possibilities in the OpenCms API to get the generated content via a "dummy" Request programmatically.

Though, I would have to study the API to get the idea :-)

Kind regards, Bernd

 I think we misunderstood each other, probably I was using the word Template in the wrong context.

To clear this up. We are right now using HTML-Files in the OpenCMS without any Templates and/or schema behind. These Files do just contain plain HTML. This is what we are using for the eMail Stuff in our Module, and this is done in JAVA and not in JSPs.

What we are looking for, is basically a way to retrieve the full HTML-file after we migrated to using Templates for them.

R,

Markus

Maybe some of the CmsXml classes might do?
Don't know. Is the content of the Email in these XML files?
Would you have to parse the XML?

I'm using the CmsHtmlMail class in a jsp to send Email like this:
   CmsHtmlMail htmlmail= new CmsHtmlMail();

   htmlmail.addTo("kuku at somewhere.de","Company GmbH");
   htmlmail.addCc("meier at somewhere.de","Company GmbH");
   htmlmail.setFrom("Infoveranstaltung at company.de");
   htmlmail.setSubject("Anmeldung");
   htmlmail.setCharset("iso-8859-2");
   htmlmail.setHtmlMsg(
   "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\"
\"http://www.w3.org/TR/html4/loose.dtd\">\r"+
"<html>\r"+
"<head>\r"+
"<title>Registrierung</title>\r"+
"<style type=\"text/css\">\r"+
"body {\r"+
"    font-family: Tahoma, Helvetica, Arial, sans-serif;"+
"    font-size: 12px;"+
"    text-align: left;"+
"    background:#f0f2f4;"+
"    color: #11316c;"+
"}"+
"td {     text-align: left;\r     vertical-align: top;\r"+
"</style>\r"+
...


And the htmlmail.send();

are not able to construct the email from it, because the email should be "transformed" to an HTML-File. Like stated, right now the XML-File is read directly and this file contains a kind of static HTML-page.
