JTable nao preenche com Mysql InnoDB

Prezados,
aconteceu algo um tanto quanto estranho comigo.
Tenho um Jtable que é preenchido sempre que um cadastro é realizado.
Tentei com vários BD’s diferentes. Em todos funciona, inclusive no mysql. Porém se utilizo o Dialect Inno DB esse preenchimento não acontece.

ja aconteceu com vocês?

abaixo meu codigo.

List<Prioridade> lista = new ArrayList();

this.se = this.sfac.openSession();

lista = this.se.createQuery("from Prioridade").list();

DefaultTableModel modeloTabela = (DefaultTableModel) jtable_Prioridades.getModel();
    modeloTabela.setNumRows(0);

    for (int i = 0; i &lt; lista.size(); i++) {
        modeloTabela.addRow(new Object[]{lista.get(i).getId_prioridade(), lista.get(i).getNome_prioridade(), lista.get(i).getQtd_dias_para_atendimento()});
    }
    jtable_Prioridades.setModel(modeloTabela);
    jtable_Prioridades.getColumnModel().getColumn(0).setMaxWidth(50);

    this.se.close();

Por que é que eu estou achando que não tem lhufas a ver com a JTable, mas, com a forma que você está fazendo a consulta?

S
sn_leonardo

Bom, uso Hibernate. Não sei se isso deve influenciar em algo.

Pergunta:
Você busca os dados no banco de dados usando o hibernate ou a JTable?

S
sn_leonardo

Busco no hibernate, eles vem em uma lista. Posterior a isso insiro no model do Jtable.

drsmachado
drsmachado

Bingo!
Se você busca pelo hibernate, popula uma lista e só depois é que preenche a JTable, podemos concluir que o problema está na configuração do Hibernate, certo?

S
sn_leonardo

Creio que não seja isso.
Se eu mudo o Dialeto ou o tento em outro banco de dados. Funciona normalmente.

O que você crê ou não é irrelevante.
Você precisa considerar os indícios, os fatos.
Faça o debug utilizando como dialect o org.hibernate.dialect.MySQLDialect e usando o org.hibernate.dialect.MySQLInnoDBDialect e me diga qual dos dois preenche a lista. Se o segundo não preencher, tua crença está errada.

Sim, com mysql dialect funciona.

E com MySQLInnoDB não.

Bom, ainda não consegui. vou colar meu arquivo de configuração.

hibernate.proxool.pool_alias pool1

Only need one of the following

#hibernate.proxool.existing_pool true

#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 bytecode reflection optimizer (disabled by default)

#hibernate.bytecode.use_reflection_optimizer true

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

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/
