Error while Installing WebAs 6.40

Hello there,

I'm getting following error messages while intalling WebAS 6.40 :

Error converting from service name=sapmsJ2E/protocol=tcp to port number. SAPRETURN=12

2. WARNING[E] 2004-04-30 18:58:21

Error converting from port number=3601/protocol=tcp to service names. SAPRETURN=12

3. ERROR 2004-04-30 19:36:23

CJS-00081 Assertion failed: in function InstallationScript_61() { var installer = new Installer(); var kdb = new KeyDB(); var context = new Context(); var gui = new Gui();

Can anybody help to install WebAS 6.40 properly ?

Thanks,
