How to fix CommandAcceptanceException in hsqldb integration test?

I use hsqldb 2.4.0 library for test my DAO layer (Hibernate 5.2.10). I create separate hibernate.cfg.xml for hsqldb in dir test/resources/hibernate.cfg.xml. But when I run test then get CommandAcceptanceException:

It's not a compatible version of syntax (If I understand correctly). But in hibernate.cfg.xml the version defined HSQLDialect:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="http://www.hibernate.org/xsd/orm/cfg">
<session-factory>
<property name="connection.url">jdbc:hsqldb:mem:auto_mag;sql.enforce_size=false</property>

<mapping resource="ru/pravvich/model/User.hbm.xml" />
<mapping resource="ru/pravvich/model/Propose.hbm.xml" />
</session-factory>
</hibernate-configuration>
Help me to find the mistake. Thank You.

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>

Vineet Reynolds / java-ee-6-galleria project running with MySQL instead of Derby

I am trying to follow / learn more about Java EE and have found a very nice article http://blog.eisele.net/2012/03/java-ee-6-running-galleria-on-glassfish.html which is a step-by-step guide of how to running it on Glassfish. The original source code can be found at "hg clone https://bitbucket.org/VineetReynolds/java-ee-6-galleria"
However, now I would like to change the Derby database to MySQL and Eclipselink since i am more familiar with it. I have succeed to run the *IntegrationTest(s) but not unit tests RepositoryTest(s).
I have changed the persistence-test.xml file to:
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"

So my real question is: Is there anybody out there that can show me how to run the Vineet Reynolds / java-ee-6-galleria project with mysql instead of derby? Hibernate or Eclipselink does not really matter, I just want to run mysql instead of derby =)
Best regards

It works.. silly mistake, just started from scratch and it fixed the problem..

Hibernate - No Suitable driver found for jdbc:mysql//*

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
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql//localhost:3306/dbname</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">commander</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">50</property>

<property name="dialect">org.hibernate.dialect.MySQLDialect</property>

<property name="current_session_context_class">thread</property>

<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>

<property name="hbm2ddl.auto">update</property>

<mapping resource="com/amakena/profile/mapping/Country.hbm.xml"/>
<mapping resource="com/amakena/profile/mapping/Gender.hbm.xml"/>
</session-factory>
</hibernate-configuration>
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.
