I have followed the software setup instructions in the book.
Ecliipse works and the "Helloworld" example worked in Chapter 1.
I am now trying to create a second project but when I double click on the main.xml file it only shows the helloworld project in the layout.
What am I doing wrong ?

the 2nd chapter is to do/edit in a java file not the mail.xml
read the page again. you will see what i mean
