Aí pessoal…

To trabalhando com hibernate e dá o seguinte erro:

16:35:31,718  INFO Environment:479 - Hibernate 3.1.3

Não foi possivel, Erro: Could not read mappings from resource: Usuario.hbm.xml

No caso, o erro tá no final, evidente… hehehe

mas então… queria saber o que pode ser de errado…

vaí vai meu Usuario.hbm.xml

<?xml version="1.0"?>
   
<!DOCTYPE hibernate-mapping PUBLIC
   "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 

<hibernate-mapping>
   <class name="Usuario" table="corresp_usr">
       <id name="usuario"  column="usuario"  type="int">
            <generator class="assigned"/>
        </id>
	<property name="UsNome" column="nome" type="string"/>

	<property name="UsSetor" column="setor" type="string"/>
	<property name="UsStatus" column="status" type="int"/>		
    </class>
</hibernate-mapping>

Não sei se tem que configurar alguma outra coisa, além das classes e disso aí em cima…

Peguei um tutorial e cheguei até este ponto…

Não tem que configurar os mapeamentos, ou algo do gênero?! o banco de dados… como configuro pro hibernate achar?

Eu precisaria de uns exemplos (mesmo que links), pra eu me basear e entender a moral…

:smiley:

Valeu!!!

Olá,

Não sei se lhe interessa Hibernate Annotations, mas acho uma boa.

#################################

Hibernate Connection Pool

#################################

hibernate.connection.pool_size 1

###########################

C3P0 Connection Pool###

###########################

#hibernate.c3p0.max_size 2
#hibernate.c3p0.min_size 2
#hibernate.c3p0.timeout 5000
#hibernate.c3p0.max_statements 100
#hibernate.c3p0.idle_test_period 3000
#hibernate.c3p0.acquire_increment 2
#hibernate.c3p0.validate false

##############################

Proxool Connection Pool###

##############################

Properties for external configuration of Proxool

hibernate.proxool.pool_alias pool1

Only need one of the following

#hibernate.proxool.existing_pool true
#hibernate.proxool.xml proxool.xml
#hibernate.proxool.properties proxool.properties

#################################

Plugin ConnectionProvider

#################################

use a custom ConnectionProvider (if not set, Hibernate will choose a built-in ConnectionProvider using hueristics)

#hibernate.connection.provider_class org.hibernate.connection.DriverManagerConnectionProvider
#hibernate.connection.provider_class org.hibernate.connection.DatasourceConnectionProvider
#hibernate.connection.provider_class org.hibernate.connection.C3P0ConnectionProvider
#hibernate.connection.provider_class org.hibernate.connection.ProxoolConnectionProvider

#######################

Transaction API

#######################

Enable automatic flush during the JTA beforeCompletion() callback

(This setting is relevant with or without the Transaction API)

#hibernate.transaction.flush_before_completion

Enable automatic session close at the end of transaction

(This setting is relevant with or without the Transaction API)

#hibernate.transaction.auto_close_session

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

#hibernate.transaction.factory_class org.hibernate.transaction.JTATransactionFactory
#hibernate.transaction.factory_class org.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 the second-level cache with JTA, Hibernate must be able to obtain the JTA TransactionManager

#hibernate.transaction.manager_lookup_class org.hibernate.transaction.JBossTransactionManagerLookup
#hibernate.transaction.manager_lookup_class org.hibernate.transaction.WeblogicTransactionManagerLookup
#hibernate.transaction.manager_lookup_class org.hibernate.transaction.WebSphereTransactionManagerLookup
#hibernate.transaction.manager_lookup_class org.hibernate.transaction.OrionTransactionManagerLookup
#hibernate.transaction.manager_lookup_class org.hibernate.transaction.ResinTransactionManagerLookup

##############################

Miscellaneous Settings

##############################

print all generated SQL to the console

#hibernate.show_sql true

format SQL in log and console

hibernate.format_sql true

add comments to the generated SQL

#hibernate.use_sql_comments true

generate statistics

#hibernate.generate_statistics true

auto schema export

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

specify a default schema and catalog for unqualified tablenames

#hibernate.default_schema test
#hibernate.default_catalog test

enable ordering of SQL UPDATEs by primary key

#hibernate.order_updates true

set the maximum depth of the outer join fetch tree

hibernate.max_fetch_depth 1

set the default batch size for batch fetching

#hibernate.default_batch_fetch_size 8

rollback generated identifier values of deleted entities to default values

#hibernate.use_identifer_rollback true

enable CGLIB reflection optimizer (enabled by default)

#hibernate.cglib.use_reflection_optimizer false

#####################

JDBC Settings

#####################

specify a JDBC isolation level

#hibernate.connection.isolation 4

enable JDBC autocommit (not recommended!)

#hibernate.connection.autocommit true

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 5
#hibernate.jdbc.batch_size 0

enable batch updates even for versioned data

hibernate.jdbc.batch_versioned_data true

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

use JDBC 3 PreparedStatement.getGeneratedKeys() to get the identifier of an inserted row

#hibernate.jdbc.use_get_generated_keys false

choose a custom JDBC batcher

hibernate.jdbc.factory_class

enable JDBC result set column alias caching

(minor performance enhancement for broken JDBC drivers)

hibernate.jdbc.wrap_result_sets

choose a custom SQL exception converter

#hibernate.jdbc.sql_exception_converter

##########################

Second-level Cache

##########################

optimize chache for minimal “puts” instead of minimal “gets” (good for clustered cache)

#hibernate.cache.use_minimal_puts true

set a prefix for cache region names

hibernate.cache.region_prefix hibernate.test

disable the second-level cache

#hibernate.cache.use_second_level_cache false

enable the query cache

#hibernate.cache.use_query_cache true

store the second-level cache entries in a more human-friendly format

#hibernate.cache.use_structured_entries true

choose a cache implementation

#hibernate.cache.provider_class org.hibernate.cache.EhCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.EmptyCacheProvider
hibernate.cache.provider_class org.hibernate.cache.HashtableCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.TreeCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.OSCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.SwarmCacheProvider

choose a custom query cache implementation

#hibernate.cache.query_cache_factory

############

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/

[/code]

help… hehehehe
