You may want to check for any logs in $ORACLE_HOME/sysman/log and consider Activating Logging and Tracing.

That error message doesn't help much. Some questions though:

* Can you confirm what version of OEM and what platform you are using?
* Has this ever worked for you?
* Can you connect to the database with SQL*Plus?
* Can you delete/rename the OEM logs and then ensure that there are no OEM java processes running and then post the logs created when you relaunch OEM and try to connect?
