Hello,
I am hoping to build a stand alone Hibernate application. The problem is that it can't find the .hbm.xml file.

I have the following main method:

package test;

import net.sf.hibernate.*;
import net.sf.hibernate.cfg.Configuration;
import VO.Action;
import org.apache.log4j.*;


/**
* Title:
* Description:
* Copyright: Copyright (c) 2003
* Company:
* @author
* @version 1.0
*/

public class TestHibernate {

public TestHibernate() {
}
public void doIt() {
try {

Configuration cfg = new Configuration();
cfg.addClass(Action.class);
SessionFactory factory = cfg.buildSessionFactory();
} catch (Exception e) {
System.out.println("error- "+ e);
}
}


And in folder VO I have an Action class, and I also have Action.hbm.xml.
Yet, I get this result:

C:\JBuilder4\jdk1.3\bin\javaw -classpath "C:\Documents and Settings\Michel de Lange\jbproject\Swing\classes;C:\log4j\jakarta-log4j-1.2.8\dist\lib\log4j-1.2.8.jar;C:\mm\mm.mysql-2.0.12\mm.mysql-2.0.12-bin.jar;C:\hibernate-2.1\hibernate2.jar;C:\hibernate-2.1\lib\dom4j.jar;C:\hibernate-2.1\lib\commons-collections.jar;C:\hibernate-2.1\lib\commons-dbcp.jar;C:\hibernate-2.1\lib\commons-lang.jar;C:\hibernate-2.1\lib\commons-logging.jar;C:\hibernate-2.1\lib\commons-pool.jar;C:\JBuilder4\jdk1.3\demo\jfc\Java2D\Java2Demo.jar;C:\JBuilder4\jdk1.3\jre\lib\i18n.jar;C:\JBuilder4\jdk1.3\jre\lib\jaws.jar;C:\JBuilder4\jdk1.3\jre\lib\rt.jar;C:\JBuilder4\jdk1.3\jre\lib\sunrsasign.jar;C:\JBuilder4\jdk1.3\lib\dt.jar;C:\JBuilder4\jdk1.3\lib\tools.jar" test.TestHibernate

What am I doing wrong? Any help is much appreciated

Hi,

That is not found either! It's not my lucky day. Anyway, I did figure it out immediately after I went to bed. It was a misunderstanding on my part of what is the classpath in JBuilder. After I put the .xml file in the directory where the class files go, it is found. Not that it helps much, because now I have this one:

java.lang.ExceptionInInitializerError: java.lang.NullPointerException at java.util.HashMap.put(HashMap.java:327)

at net.sf.hibernate.type.TypeFactory.<clinit>(TypeFactory.java:50)

at net.sf.hibernate.cfg.Binder.getTypeFromXML(Binder.java:894)

at net.sf.hibernate.cfg.Binder.bindSimpleValue(Binder.java:403)

at net.sf.hibernate.cfg.Binder.bindRootClass(Binder.java:257)

at net.sf.hibernate.cfg.Binder.bindRoot(Binder.java:1204)

at net.sf.hibernate.cfg.Configuration.add(Configuration.java:247)

at net.sf.hibernate.cfg.Configuration.addInputStream(Configuration.java:281)

at net.sf.hibernate.cfg.Configuration.addClass(Configuration.java:322)

at test.TestHibernate.doIt(TestHibernate.java:25)

at test.TestHibernate.main(TestHibernate.java:42)

Exception in thread "main"


Cheers,

Sorry, bad typing...

Try

http://www.hibernate.org/hib_docs/reference/html/session-configuration.html

and

Your latest problem is again a classpath issue - you don;t have all the required JARs. Look at lib/README.txt in your Hibernate distribution.


Sherman

Hello,

I do have them all. I have all jars in the hibernate/lib as well as hibernate2.jar on my classpath.

One thing that puzzles me, but I don't know whether this is related is this: If there are 2 databases in hibernate.properties, how does hibernate know which to choose?

Best regards,

Post your hibernate.properties.


Sherman

Here it is:

### Transaction API ###
#######################

## the Transaction API abstracts application code from the underlying JTA or JDBC transactions

#hibernate.transaction.factory_class net.sf.hibernate.transaction.JTATransactionFactory
#hibernate.transaction.factory_class net.sf.hibernate.transaction.JDBCTransactionFactory


## to use JTATransactionFactory, Hibernate must be able to locate the UserTransaction in JNDI
## default is java:comp/UserTransaction
## you do NOT need this setting if you specify hibernate.transaction.manager_lookup_class

#jta.UserTransaction jta/usertransaction
#jta.UserTransaction javax.transaction.UserTransaction
#jta.UserTransaction UserTransaction


## to use JCS caching with JTA, Hibernate must be able to obtain the JTA TransactionManager

#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.JBossTransactionManagerLookup
#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.WeblogicTransactionManagerLookup
#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.WebSphereTransactionManagerLookup
#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.OrionTransactionManagerLookup
#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.ResinTransactionManagerLookup



##############################
### Miscellaneous Settings ###
##############################

## print all generated SQL to the console

#hibernate.show_sql true


## auto schema export

#hibernate.hbm2ddl.auto create-drop
#hibernate.hbm2ddl.auto create
#hibernate.hbm2ddl.auto update


## specify a JDBC isolation level

#hibernate.connection.isolation 4


## set the JDBC fetch size

#hibernate.jdbc.fetch_size 25


## set the maximum JDBC 2 batch size (a nonzero value enables batching)

hibernate.jdbc.batch_size 0


## enable use of JDBC 2 scrollable ResultSets (specifying a Dialect will cause Hibernate to use a sensible default)

#hibernate.jdbc.use_scrollable_resultset true


## use streams when writing binary types to / from JDBC

hibernate.jdbc.use_streams_for_binary true


## specify a default schema for unqualified tablenames

#hibernate.default_schema test


## use a custom stylesheet for XML generation (if not specified, hibernate-default.xslt will be used)

#hibernate.xml.output_stylesheet C:/Hibernate/net/sf/hibernate/hibernate-default.xslt


## enable outerjoin fetching (specifying a Dialect will cause Hibernate to use sensible default)

#hibernate.use_outer_join false


## set the maximum depth of the outer join fetch tree

hibernate.max_fetch_depth 1


## enable CGLIB reflection optimizer (enabled by default)

#hibernate.cglib.use_reflection_optimizer false


## enable the query cache

#hibernate.cache.use_query_cache true


## choose a cache implementation

#hibernate.cache.provider_class net.sf.ehcache.hibernate.Provider
#hibernate.cache.provider_class net.sf.hibernate.cache.EmptyCacheProvider
hibernate.cache.provider_class net.sf.hibernate.cache.HashtableCacheProvider
#hibernate.cache.provider_class net.sf.hibernate.cache.TreeCacheProvider
#hibernate.cache.provider_class net.sf.hibernate.cache.OSCacheProvider
#hibernate.cache.provider_class net.sf.hibernate.cache.JCSCacheProvider
#hibernate.cache.provider_class net.sf.hibernate.cache.SwarmCacheProvider


############
### JNDI ###
############

## specify a JNDI name for the SessionFactory

#hibernate.session_factory_name hibernate/session_factory


## Hibernate uses JNDI to bind a name to a SessionFactory and to look up the JTA UserTransaction;
## if hibernate.jndi.* are not specified, Hibernate will use the default InitialContext() which
## is the best approach in an application server

#file system
#hibernate.jndi.class com.sun.jndi.fscontext.RefFSContextFactory
#hibernate.jndi.url file:/

#WebSphere
#hibernate.jndi.class com.ibm.websphere.naming.WsnInitialContextFactory
#hibernate.jndi.url iiop://localhost:900/

You have to configure hibernate is an hibernate.cfg.xml file

Must I have 2 files:
1) hibernate.properties
2) hibernate.cfg.xml
?

What must I put in hte cfg.xml file?

You'll have 2 cfg.xml (1 for each DB) and 1 .properties
I usually put everything in cfg.xml
I use hibernate.properties for System level proeprties (see reference guide)
