Hi,

I-m an absolute begginer in Hibernet. And I got stuck at the very start line.

Mine is a web application that is beeing developed under netbeans (3.5.1)
Following a recomendation from a collegue we are trying to use hibernate to persist our objects on a MySql database.

Now, I have tryed to follow the Quickstart, and anything else I could get my hands on, but could not make it run.

Any hints, tips, whatever is welcome.

----------------------

In my last atempt I have mannaged to make the app run, but get a bunch of exceptions.

I-m thinking maybe I have not configured tomcat well, or the netbeans ide.

I-m at a lost.

Thanks
Mata

netbeans shouldn't have much to do with things. However, if you are using an embedded tomcat with netbeans, you had better make sure you've got your jars and hibernate.properties in the right spot. For a web app, jars should be in application_folder/WEB-INF/lib and properties in application_folder/WEB-INF/classes

hope that helps, otherwise you should post more info on the exact errors.

Hi again. More info.

Now I-m getting a

SEVERE: Could not compile the mapping document
java.lang.ClassNotFoundException: Person.class
at java.net.URLClassLoader$1.run(URLClassLoader.java:198)
at java.security.AccessController.doPrivileged(Native Method)

I don-t know. Person.Class is on the direcotry.

This is a simple example. The person has a name. And i want to save it in the database.

Thanks again
Mata

make sure the Person.hbm.xml file is in the same location as Person.class

WEB-INF/classes/Person.hbm.xml
WEB-INF/classes/Person.class

Then make sure your mapping has the correct class i.e.
<class
name="Person"
table="person"
>

Hi again. Thanks for your troubles.

I have moved on a little. Now I can-t find the database.

This is what I get>

Sep 5, 2003 2:37:14 PM net.sf.hibernate.connection.DatasourceConnectionProvider configure
SEVERE: Could not find datasource: AppServ/mysql/data/esee
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:640)

Thaks a lot

You should really try the "Quickstart" document again. Also try to read it this time. It's not faster or easier if we read it for you. :)

much nicer then RTFM :-)

OK... I apologice If you feel i'm out of my depth. I'm just trying to lean.

I have gone over the Quickstart (once more now). And I know I am missing something obvious (some casesencitive issue- a como somewhere) and I know you can not help me at such level. But maybe just point into the right direction If you have an aswer to my troubles.

Again, I am really at a loss. I'm Tired, frustrated. Even the topics in the beginners forums seem too much for me, SINCE I HAVEN'T BEEN ABLE TO MAKE IT WORK.

Now, I have come agaist new technologies before, and usually, all one need is a little push in the right direction. Give me bread and I'll eat today, teach me how to cook, and I'll eat everyday. (Or Sth among those lines)

Thanks again. And again, I apologice If I am wasteing your time.

Yours
Mata

PS: What does "RTFM" stand for?

did you put hibernate.properties in
application/WEB-INF/classes

is it configured correctly. Could not find datasource seems to suggest that is it is not.

I use postgresql

hibernate.dialect net.sf.hibernate.dialect.PostgreSQLDialect
hibernate.connection.driver_class org.postgresql.Driver
hibernate.connection.url jdbc:postgresql://localhost:5432/mydatabase
hibernate.connection.username user
hibernate.connection.password pass
