There are several methods available in LiveCycle to do so.
1. By inbuilt submit button available in the object library.
2. By a regular button : Drag a regular button from the object library to the designing space.Change the control type as Submit.Then in the submit url field mention the url or your mail for ex mailto:email@example.com.
3. You can also do a bit of scripting in the regular button.
you can also just put in mailto:
and then it will open up whatever email program the person has, attach the pdf and be ready for the recipients email address. This way you don't have to specify one recipient. That is how we use it.
Your information was really helpful, thanks. The last issue I am seeing is that the form works for me but not for a colleague. I have Adobe Pro, (reader 9) and my colleague does not have Pro but has Reader X (10). What is needed for this Submit process to work?
You need to make the form reader enabled to that it will work in Acrobat as well as Adobe Reader. Open a form in Acrobat and follow the procedure given below to make it reader enable.
In Acrobat - X : File -> Save As -> Reader Extended PDF -> Enable Additional features.
