Hi All, My application runs using JBOSS323. I have JBOSS323 installed on Linux and on a Windows Server 2003. On linux when an entity is searched one SQL query is executed. On the Windows Server 2003 for each searched entity several SQL queries are executed: one for each cmp-field. The standardjbosscmp-jdbc.xml are in both instances equal. Is there any other parameter I need to set and may have overlooked on the Windows Server 2003? A simple query does take a lot of time when every cmp-field is retrieved separately. Thanks for an answer of for a link so that I can investigate further. Sponiza View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128956#...
