我在JBoss AplicationServer上啓動了一個使用ICEFaces和Hibernate的項目，現在我被卡住了讓Hibernate工作。JBoss Hibernate與SessionFactory和JNDI衝突
問題是我的DAO類不能得到SassionFacade。 我覺得休眠也沒有創造一個因爲與JNDI
相同衝突我做了什麼至今的：
建立我的MySQL數據庫。我用這個教程：https://community.jboss.org/wiki/DataSourceConfigurationInAS7
（我安裝了JDBC驅動程序的模型）不那麼肯定，如果它的工作，因爲在服務器啓動時，它看起來像他加載其他驅動程序
18:30:26,980 INFO [org.jboss.as.connector.subsystems.datasources] (ServerService Thread Pool -- 26) JBAS010403: Deploying JDBC-compliant driver class org.h2.Driver (version 1.3)
比我幾乎用本教程的第一面：
http://www.packtpub.com/article/developing-applications-with-jboss-and-hibernate-1
，它看起來喜歡它的工作，我看到我的數據庫和表，但該標誌會話工廠是空的，告訴我這樣的警告：

我記得在同一時刻，我有相同的Session Factorys，那裏的機器人不記得我改變了他們的diassapeard。
因爲它僅僅是一個警告，我會在本教程併成功地生成的類到我的表和DAO的比我寫一個小的測試程序，並使用DAO中的一個，並得到以下錯誤：

我的休眠配置（hibernate.cfg.xml中）
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

的從Hibernate生成的DAO（PlattenHome.java）
package db.fassaden.hibernate;

public class PlattenHome {
private static final Log log = LogFactory.getLog(PlattenHome.class);
private final SessionFactory sessionFactory = getSessionFactory();
protected SessionFactory getSessionFactory() {
try {
return (SessionFactory) new InitialContext().lookup("SessionFactory");
}
catch (Exception e) {
log.error("Could not locate SessionFactory in JNDI", e);
throw new IllegalStateException("Could not locate SessionFactory in JNDI");
}
}
...
public Platten findById(java.lang.Integer id) {
log.debug("getting Platten instance with id: " + id);
try {
Platten instance = (Platten) sessionFactory.getCurrentSession()
.get("db.fassaden.hibernate.Platten", id);
if (instance==null) {
log.debug("get successful, no instance found");
}
else {
log.debug("get successful, instance found");
}
return instance;
}
catch (RuntimeException re) {
log.error("get failed", re);
throw re;
}
}
，我如何使用它：
public void testhibernate(ActionEvent e){
PlattenHome pdao = new PlattenHome();
Platten platte = new Platten();
platte = pdao.findById(1);
this.setName(platte.getMaterial());
System.out.println("test");
System.out.println(platte.getMaterial());
}
我只注意到，如果我現在需要重新編譯Hibernate配置後，服務器啓動它給我另一個警告

我在我的應用程序中有400個dao類，由hbm2java插件生成，我認爲這不是可行的解決方案....然後，我需要修改由hbm2java生成的所有dao，是否有更好的解決方案？ –
