look in server.log and boot.log files.
Ok. I do not see anything obvious in the logs. The error above is related to IIS. We have that pointing to port 8028. When I go to the server:8028/portal i get the above error b/c its not there in the wwwroot folder. When I go to just http://localhost, I get the error Internet Explorer cannot display the webpage. The log files have dropped from 60M to 2M.
The file I changed is C:\McKesson\jboss-portal-2.6.4\server\default\deploy\jboss-portal.sar\META-INF\jboss-service.xml. I changed the Gateway. I noticed that there is a setting above this one <depends>portal:service=Hibernate</depends>. In the old log files, there are tons of messages org.hibernate. But the new much smaller logs do not mention hibernate.
[org.jbpm.persistence.db.DbPersistenceService] creating hibernate session --> In old logs but not new ones.
So you use IIS as front-end? Any error in its logs?
