Thanks!
I think, if JUL requires .properties in that situation, I'll use log4j instead of it.

Hmm, I didn't found good examples about sl4j.

If I have a method:
... private static FileHandler handler = null; private static java.util.logging.Logger logger = null; static { try { handler = new FileHandler("sql.log", true); handler.setFormatter(new SimpleFormatter()); logger = java.util.logging.Logger.getLogger("test"); logger.addHandler(handler); } catch (IOException ioe) { ioe.printStackTrace(); } } ... public void test(){ em.createQuery("SELECT u FROM UserEntity u").getResultList(); } ...
How can I log generated sql query to the file "sql.log"?

Hello Angel!
I am using 3.3.1 version. How can I plug JUL?

Hello, ranchers!
I want to turn on sql logging using
<property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/>
How can I use a logger from JUL instead of log4j in that situation?
Thanks in advance.

Thanks! Finally it is done!

Hmm, thanks, but the same exception is thrown without these properties in persistence.xml. It is thrown even if there is no properties. Has anyone other idea's?

I want to use hibernate as a JPA provider, so do I need hibernate.cfg.xml?
This is persistence.xml
<?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0"> <persistence-unit name="photo" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java:comp/env/jdbc/mysql</jta-data-source> <class>entities.UserEntity</class> <properties> <property name="hibernate.archive.autodetection" value="class, hbm"/> <property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/> <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/photo"/> <property name="hibernate.connection.username" value="root"/> <property name="hibernate.connection.password" value="1234"/> <property name="hibernate.c3p0.min_size" value="5"/> <property name="hibernate.c3p0.max_size" value="20"/> <property name="hibernate.c3p0.timeout" value="300"/> <property name="hibernate.c3p0.max_statements" value="50"/> <property name="hibernate.c3p0.idle_test_period" value="3000"/> <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> </properties> </persistence-unit> </persistence>
Context.xml in tomcat

I checked connection using my IDE. It's ok.

Hello, ranchers!
I have the following method in a JSF bean
public static boolean saveUser(LoginBean lb){ EntityManager em = HibernateUtil.getEntityManager(); EntityTransaction t = em.getTransaction(); t.begin();//exception UserEntity user = new UserEntity(); user.setName(lb.getName()); user.setPassword(lb.getPassword()); em.persist(user); em.flush(); t.commit(); return true; }
I have tried this code with MySql and Postgres, application server is Tomcat 6.14. This is the exception:

Has anyone any ideas about this?

Hello, ranchers!
I tried to develop "Hello World" using IceFaces, but always get an error
"Servlet Persistent Faces Servlet is not available". Does anyone have a good link for "helloworld"?
Thanks for any help.

I have read EJB in Action, O'Reilly's book, Zaikin's guide (the most useful).
I used Whizlabs (failde, failed, pass(42), pass(44)) then Ethuware (all passed 62-66%).
There are some wrong questions in both simulators. Whizlab's difficulty is like real exeam, Ethuware is more difficult.

Thanks to all ranchers for help

Thanks a lot.
But I have only A1-A3 in my spec (from SCBCD links). Could you give me direct link for your spec?

Hello dear ranchers!
I have read O'Reilly book, and then started read specs. I've found @EmbeddableSuperClass annotation in 2.1.9.3 paragraph.
Behaviour of this annotation is exactly like @MappedSuperClass, and I don't see @EmbeddableSuperClass in Java EE packages.
Could anyone explain this moment? Thanks.

I have faced another problem last week. I don't have a credit card to pay, so I have bought Whizlabs simulator using wire transfer. But I can't buy Ethuware this way!
If mr. Paul Anil could help, I'll be very happy.

Thanks.
You said about GUI "Drag and Drop" questions. How many DND questions are in exam? I remember, that PC worked very slow when I answered this type of questions during SCWCD...
