I'm having problems with Hibernate mapping generation with 4.1 GA.
Eclipse SDK: 3.1.2
MyEclipse: 4.1.1GA
Mysql: 5.0
Driver: mysql-connector-java-3.1.12-bin.jar

CREATE TABLE users (
user_id int(24) unsigned NOT NULL auto_increment,
username varchar(50) NOT NULL,
password varchar(10) NOT NULL,
PRIMARY KEY(user_id)
);

When I connect to the mysql, it is ok, I can see all the databases, but When I Hibernate mapping generation, it give me this error:
An internal error occurred during "Generating Artifacts"
Please help me.
Here is hibernate.cfg.xml

<hibernate-configuration>

<session-factory>
<property name="connection.username">root</property>
<property name="connection.url">jdbc:mysql://localhost/demo</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="myeclipse.connection.profile">vipinfo</property>
<property name="connection.password">password</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

</session-factory>

</hibernate-configuration>

Thank you very much![/b]

Hey soarwolf ,

It looks that you have typing error in hibernate.cfg.xml

Please check this line :

<property name="connection.url">jdbc:mysql://localhost/demo</property>

Is your database Demo or demo - set same database name like in database explorer
It's better taht you edit hibernate.cfg.xml with MyEclipse configuration editor (when you have good setting for connection profile and you have it) and you simple choose connection profile - MyEclipse will do other for you.

I suppose that your warning is

your hibernate project is configured for jdbc:mysql://localhost/Demo, but you are generating artifacts from jdbc:mysql://localhost/demo.

different is Demo and demo

Best regards

soarwolf

hello guys,

I am getting the same error when I am trying to Hibernate Reverse Engineering on MyEclipse 5. Have you guys encountered any problems in "Generating Artifacts" when doing this Reverse Engineering?

Thanks

Hi Peco,

Here is my configuration in hibernate.cfg.xml.

I have used the preconfigure Database Driver in the DB Connect Profile. This set up this configuration below.

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">


<hibernate-configuration>

<session-factory>
<property name="max_fetch_depth">1</property>
<property name="myeclipse.connection.profile">SYB_NJES_DEV_02</property>
<property name="connection.url">jdbc:sybase:Tds:sybnjesdev02.ny.cantor.com:4200</property>
<property name="connection.username">rteodosio</property>
<property name="connection.password">espeed</property>
<property name="connection.driver_class">com.sybase.jdbc2.jdbc.SybDataSource</property>
<property name="dialect">org.hibernate.dialect.SybaseDialect</property>

</session-factory>

</hibernate-configuration>

I could drag and drop the tables from DB Browswer into Hibernate Mapping, but executing the reverse engineering mapping gives me the same error message.

Thanks,
Ron

Hi Peco,

After many head banging, the problem here is the version of log4j being used in hibernate as log provided this evidence:

java.lang.NoSuchMethodError: org.apache.log4j.Category.log(Ljava/lang/String;Lorg/apache/log4j/Level;Ljava/lang/Object;Ljava/lang/Throwable;)

in log4j version in the MyEclipse 5 uses Piority object instead of Level. I found an article talking about this incompatiblity:

http://mail-archives.apache.org/mod_mbox/logging-log4j-dev/200512.mbox/%3C438F0EEB.7000104@ptc.com%3E

Do you know by chance what version of log4j are you guys using in development of MyEclipse 5 in hibernate lib?

Thanks,
Ron
