com.sap.portal or com.sapportals

[Former Member]

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 Am I using outdated jars or outdated examples?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.

HI,

For HTMLB use

import com.sapportals.htmlb.event.Event;

import com.sapportals.htmlb.page.DynPage;

import com.sapportals.htmlb.page.PageException;

import com.sapportals.htmlb.table.DefaultTableViewModel;

import com.sapportals.htmlb.table.TableView;

import com.sapportals.portal.htmlb.page.JSPDynPage;

DID you add the

ECLIPSE_HOME/plugins/com.sap.ep.applicationDevelopment/com.sap.portal.htmlb_api.jar

in u r build path

Hi,

All the jars are available in the folder '<drive>:\usr\sap\J2E\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\portalapps'

As you find build errors search for the respective classes using 'Jar Finder' /people/kirupanand.venkatapathi2/blog/2006/01/02/using-jar-class-finder and add them to your build path.

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:
