i am using ES5.0 and i installed Enterprise adpter 4.5,but when i am trying to start the adapter thru adapter config tool it’s giving Error. also after installation adapter service is not showing in Control panel/services box . i can’t see adpter service running while ES service is running on 6849 port.
The steps i followed:
Installed the ES5.0
Install JVM1.3

any help would be highly appreciated

Exactly which adapter are you trying to start?

The Adapter Monitor service runs on port 6853. Do a netstat -a and check if the port 6853 is open (should either see a Listening or Established status).

Also when you installed the EI Adapters, what was the root directory?.. was it inside c:\webmethods5 or c:\wment41?.

You may want to check and let us know with an update.
