SAP Web AS 6.40 - Error during startup

I am installing Web AS 6.4 from a set of DVDs (partners phase 3 ramp up) sent to us directly from SAP in a Solaris 5.8 64bit machine.

I enter all information requested by SAPinst from INSTALLATION MASTER DVD and everything seems to be installed correctly. However, there is a step (Start SAP J2EE Engine) in the end of the installation script where seems that SAPinst restarts the J2EE server. After a log time waiting, I finally get the error:

ERROR 2005-01-21 17:18:16

CJS-20024 J2EE engine JC00 of SAP system GBS did not come up after 800 seconds: giving up.

Could you please help me to understand what is happening?

Thanks a lot
