[opencms] [opencms-dev] Create a scheduled job from jsp

[Luis Rodriguez Fernandez]

Thanks for your code. This solution let me load the static content for the mail (the head, for example), but doesn´t make with the dynamic content, the jsp in this case because it doesn' t call to the jsp engine.

Thanks. Luis

So, the real problem is calling an url from a java code and get the resulting html (whith all the formatting css, headers, and other stuff in it), then put this html code into one email and send it, isn't it ?

This code gets the html (or jsp) from you site and stores in a local file...
