One thing to consider. Take a look at the database and find out how many licenses you have. When I was an OJB/DBCP noob I had set the maxActive higher than the number of available connections in the database.

Check your OJB.properties and set maxActive to the same value as maxActive of the connection pool settings in repository_database.xml. I am not sure about it but your problem happened to me once this way and it was solved by doing as i suggest. regards, Dennis 2006/10/26, Marwane <[EMAIL PROTECTED]>: > hi > we have a web application
