JWSP-1.2 Duke Bookstore - connection problem
Jeg har problemer med bookstore1 eksemplet i JWSP-1.2. Jeg mener, at det skyldes et eller andet med Datasource objektet. Problemet opstår når ds.getConnection() udføres. Når BookStore1 applikationen startes, f.eks ved ant install-config kommandoen eller fra Tomcat's manager, ses i pointbase's server window en uendelig række af logon/logoff.
Jeg har checket alt 117 gange, Tomcat virker, Pointbase virker og books-tabellen i sample-databasen blev oprettet uden problemer. Men åbenbart er der et eller andet jeg har overset. Herunder er et uddrag fra launcher.server.log filen. Jeg vil være taknemlig, hvis der er nogen som kan lede mig på sporet af årsagen til problemet.

Problemet er forsvundet! Det hjalp at slette alt og geninstallere!
Men når jeg i administrator konsolen klikke på "Data sources" under "Context (/bookstore1) - Resources", får jeg nedenstående exception dump. Er det en "bug" eller har jeg stadig et problem et eller andet sted?. Vælger jeg i stedet "Data sources" under globale resourcer vises de resourcer, jeg har defineret v. hjælp af administrator konsolen.
