Or, if he doesn't have a current investment in Hibernate, use Cayenne (which doesn't have lazy loading problems/etc).

Are you ever committing your transaction? _____ From: Mark [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 24, 2006 11:16 AM To: Tapestry users Subject: Hibernate persisted data never makes it to DB Hi everybody, I have a problem with my persistence and I am not sure if it has to do with the often-discussed Hibernate-Tapestry interaction, OpenSessionInView filters (and me not using any), just my cache settings or something entirely different altogether. I am running Tapestry with Spring and Hibernate. Spring has the Hibernate3 session factory configured through a org.springframework.orm.hibernate3.LocalSessionFactoryBean I am not using any OpenSessionInView filters yet - intentionally, because I wanted to run into the lazy-load problems first in order to verify that what I would then do will actually fix the problem. Here is the problem that I currently have: When I start up Tomcat, Hibernate gets properly initiated, loads my mappings, shows the proper DB connection details (MySQL 5.0) and then waits for work. I go to my app's "Add" page (just basic CRUD for now) to add a new oject. The Tomcat console shows the proper SQL INSERT statement generated by Hibernate. However, the database is still empty. I add another bunch of objects, go back to my list page, and they are all there. The database table is still empty. I thought this probably has to do with the fact that Hibernate keeps the data cached for a while untit it really writes it to the DB. But even after I shut down Tomcat, the table is empty. When I start up again, all my records are gone. I also thought that Tomcat maybe shuts down before Hibernate could persist everything and that therefore there needs to be a shutdown-listener that tells Hibernate to flush the cash to the DB. If that was the case, I would expect that hundreds of beginners made the same mistake as I did and there should be plenty of info about this on the web, but google came back with nothing... Both Tomcat console and Tomcat logs show absolutely no error message - neither related nor unrelated. Does anybody know what the problem is? This is the first time ever that I play with all Hibernate, Tapestry and Tomcat, so it may very well be a stupid error by a bloody beginner ... :-) Thanks, MARK P.S.: My log4j is configured to write out a log file for hibernate, but I can not find it. Where would that get created? log4j.appender.file=org.apache.log4j.FileAppender log4j.appender.file.File=hibernate.log log4j.appender.file.layout=org.apache.log4j.PatternLayout log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
