You might be able to use the Commons DBCP PerUserPoolDataSource as Dain suggests but it'll take some patching to get it wired in. This is the class that creates the DataSources inside OpenEJB org.apache.openejb.resource.jdbc.DataSourceFactory http://svn.apache.org/viewvc/openejb/tags/openejb-3.1/container/openejb-core/src/main/java/org/apache/openejb/resource/jdbc/DataSourceFactory.java?view=markup You might be able to patch it to create PerUserPoolDataSource instead. -David Paul Spencer Dain Sundstrom wrote: Assuming you are using straight JDBC or a persistence framework designed for per-user connections, I believe that the org.apache.commons.dbcp.datasources.PerUserPoolDataSource pool can do what you want, but I've never used per-user pools myself.
