Looks like , J2EE is having a problem connecting to the DB.Pls. chk. the following
-If you have configured the loop-back adapter , if installing on a local system & updated the /etc/host file with your ip address and host name.
or if the system is part of some n/w group and has ip address assigned ?
-Jdk 1.4 version is installed in your system
-Enough free Disk space available in the system
-How much RAM your system has which windows version you are using  ?
-Is the DB is coming up properly ? its error related to this. check the logs.
-If the ports used by sap install / run used by other services running on the system ? & user have admin. privileges on the system .
Pls. update with your findings on above same , for the step next ...
Thanks ,
