We will support only those databases for which we have config files in jboss-messaging-1.2.0.GA\examples\config - mysql, mssql, portgre, sybase, db2 and oracle. (+hsql for non-clustered) If there is something else, let me know. Here is a screenshot of the JEMS installer's Messaging config dialog (no db, because it uses a datasource defined earlier, which is used for other things too): http://anonsvn.jboss.org/repos/installer/jems-installer/branches/Branch_J... And this is how it looks in the dedicated installer (db choice is for clustered configurations only, it's not very clear at the moment): http://anonsvn.jboss.org/repos/installer/jems-installer/branches/Branch_J... anonymous wrote : The question is, whether on not we want the user to be able to change these on install, or should we stick with the defaults? I was hoping you would know :) . If you have any preferences about this comment here. We do have Advanced/Standard selector in the installer (standard is for the defaults). This Messaging Configuration dialog is displayed only if the user is in advanced mode. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4026941#...
