Why can I not connect to the Enterprise Portal?

I downloaded & installed the free trial version of the Web AS 6.40 on my laptop. I developed some test portal application and want to deploy this on the WEB AS server. The message I get is each time :

Unable to connect to the Portal. Operation failed. Connection refused:connect. Please make sure the server localhost:8080 is running.

Settings J2EE Engine

"SAP J2EE Engine is installed on local host" checked

system:J2E

J2EE instance:0

SCS instance: 1

Settings Portal server:

alias: leen

host: localhost

Port: 8080

Login: administrator

Description: test

I started the SAP system with Start->Programs->SAP Management Console, right clicking the system node J2E and selecting start. Does this start also the EP??

What do I wrong?
