I am trying to run hibernate in a Java project that is referenced by a web project. Simple enough except that I can't get hibernate to connect to my database. I have a lot of people describing this problem and getting tons of answers however none seem to work for me.
This is how my hibernate.cfg.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

I debugged the code to DriverManagerConnectionProvider class, the exception is thrown attempting the getConnection() method
Connection conn = DriverManager.getConnection(url, connectionProps);
I checked the url and connectionProps and they are the ones in hibernate.cfg.xml
I have added mysql-connector-java-3.1.14-bin in my tomcat \lib folder and I can see it in eclipse under Libraries>Apache Tomcat v6.0>. I also added it to my %Javahome%\lib\ext and my CLASSPATH variable (which I know is useless by I am kindda desperate).
I made sure my driver is installed properly by running the following code just before the session.beginTransaction() which in turn leads to DriverManagerConnectionProvider.getConnection()
Class.forName("com.mysql.jdbc.Driver");
Properties connectionProperties = new Properties();
connectionProperties.put("user", "root");
connectionProperties.put("password", "root");
DriverManager.getConnection("jdbc:mysql://localhost:3306/dbname", connectionProperties);
I noticed that emitting the first line causes the same exception.

WARNING: --Erroring: batchId[24] message[org.hibernate.exception.JDBCConnectionException: Cannot open connection]
I appreciate all the help I could get. Thanks in advance.
Versions Used: Tomcat v6.0 - Hibernate 3.6.6 - Java 6 - Eclipse 3.5.2 R35x
You forgot the colon after "mysql":
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/dbname</property>
Here's the doc for the URL format:
jdbc:mysql://[host][,failoverhost...][:port]/[database]
No suitable driver always means that the driver JAR was loaded, but your URL syntax is incorrect.
jdbc:mysql://localhost:3306/dbname
You are missing the : after mysql
Another reason is that the driver class is not found, make sure your driver class is successfully loaded.

My hibernate properties are correct. I am able to test connect from my websphere admin console.
when I goggled Connection refused: connect. ERRORCODE=-4499, SQLSTATE=08001 error its says need to set tcpip property
db2set DB2COMM=tcpip
db2stop
db2start
I am not sure where should run these commends, I tried to db2 commend window, it doesn't work.
I am using db2jcc4.jar which I have used for connection pool form websphere admin console
Please help me to fix this issue.
Thanks
DB2 uses port 50000 by default, but you have specified 5000 in your JDBC URL. Unless you specifically modified your DB2 configuration after installing it, I would try adding a zero to your port number:
<property name="connection.url">jdbc:db2://localhost:50000/sample</property>
I have an entity class named "NewsArticle" that has about 20 instance variables, when I use session.save() to insert the entity object into mysql, I got the following error. I have searched the internet but found no solution. I am sure I am using MySQL dialect for hibernate queries. What does the error message indicate where might be wrong though?

I had the same problem, hope my solution work for you too:
1: since you're using hibernate-c3p0-4.1.10.Final.jar, your provider_class should be:
<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
from Error Caused by: org.hibernate.HibernateException: Could not instantiate connection provider [org.connection.C3P0ConnectionProvider]
Also, make sure you include both
c3p0-0.9.1.jar and hibernate-c3p0-4.2.1.Final.jar (should be in the same folder "\hibernate-release-4.2.1.Final\lib\optional\c3p0\" )
I ended up downloading the latest Hibernate release (4.2.1) here http://planet.jboss.org/post/hibernate_orm_4_2_1_final_and_4_1_12_final_released
and updating all the hibernate related jars in my project to get it to work properly, since the download link in eclipse only has the 3.6.0 Final version (JBoss Hibernate - http://download.jboss.org/jbosstools/updates/stable/)
Add the above lirary jar files found in your hibernate distribution lib directory
I have issue with reverse engineering from database using hibernate 5. I am able to generate the hibernate.reveng.xml file but when i run using the Hibernate Code Generation Configurations, it give me the error as stated below.
I have tried with adding "hibernate." to my xml files but same thing, i can generate the hibernate.reveng.xml but not able to run Hibernate Code Generation Configurations.
This is my xml file:
<hibernate-configuration>
<session-factory>
<property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="connection.password">Password123!</property>
<property name="connection.url">jdbc:sqlserver://localhost:1433;databaseName=TestDB</property>
<property name="connection.username">sa</property>
<property name="dialect">org.hibernate.dialect.SQLServer2012Dialect</property>
</session-factory>
</hibernate-configuration>
This is the error i am facing.

Try This.
Change <property name="dialect">org.hibernate.dialect.SQLServer2012Dialect</property> to <property name="hibernate.dialect">org.hibernate.dialect.SQLServer2012Dialect</property>
I ended up deleting the whole configuration file and redo all the step to reverse engineer my pojo as per what I have posted and is working now. But I have not idea why.
