Com.sap.portal or com.sapportals

Question

I'm new to the development of EP and WAS pages. I found some easy examples. But as soon as I try to compile them I get compiler errors.
<u>the example starts like this</u>...
import com.sap.htmlb.*;
import com.sap.htmlb.enum.*;
import com.sap.htmlb.page.PageException;
import com.sap.portal.htmlb.page.JSPDynPage;
public class DynPageOne extends JSPDynPage {
I downloaded the netwaever libraries (netweaverlibraries.zip) from the EP itself. But the packages contained in i.e. htmlb.jar are all com.<b>sapportals</b> and not com.<b>sap</b>.
Any ideas? Am I using outdated jars or outdated examples?
Thanks for any help.
Martin

Answer 1

Salla, thanks for the immediate reply.
I got the Java classes compiled with the jars I downloaded, but I had to change the reference to com.sapportals...
As far as the directory that you mentioned I only have subdirectoried with html pages, images and other files, but no standard jars that would contain i.e. the htmlb package.
With the changed reference I get the following entires in the log file that I cannot explain:
