Can anyone help me with this
my cfg.xml
<session-factory>
<!-- <property name="hbm2ddl.auto">create</property> -->
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="connection.url">jdbc:postgresql://10.51.33.60:5432/ddddd</property>
<property name="connection.username">abc</property>
<property name="connection.password">abc</property>
<property name="connection.driver_class">org.postgresql.Driver</property>
<property name="show_sql">true</property>
<mapping resource="in/abc/def/Dao/ServiceVO.hbm.xml" />
</session-factory>
i have not yet mentioned any maximum connections

You need to configure connection pooling:
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="hibernate.connection.url">jdbc:postgresql://10.51.33.60:5432/ddddd</property>
<property name="hibernate.connection.username">abc</property>
<property name="hibernate.connection.password">abc</property>
<property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
<!--connection pool settings-->
<property name="hibernate.c3p0.min_size">5</property>
<property name="hibernate.c3p0.max_size">20</property>
Make sure you include hibernate-c3p0 dependency too:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-c3p0</artifactId>
<version>${hibernate.version}</version>
</dependency>

How to use HikariCP with jdk1.7 to get the best result

I have read a lot about hikariCP and how it is "the fastest connection pool" and there is no deadlock reported with it. But when I compared it with tomcat-jdbc I get almost the same response times for both (if not tomcat-jdbc is faster). Further more I got an Exception when using hikariCP, stack trace can be found below. I feel that I did not configure the connection pool correctly.
note: my application should accept up to 70 transactions per second.
I am using:
HikariCP-1.4jdk 1.7 Spring Framework 3.2 Hibernate 4
and this is my HikariCP configuration:
<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
<property name="poolName" value="springHikariCP" />
<property name="maximumPoolSize" value="7"/>
<property name="idleTimeout" value="9000"/>
<property name="connectionTimeout" value="120000"/>
<property name="jdbcUrl" value="${app.jdbc.url}"/>
<property name="username" value="${app.jdbc.username}"/>
<property name="password" value="${app.jdbc.password}"/>
<property name="driverClassName" value="${app.jdbc.driverClassName}" />
</bean>
<!-- HikariCP configuration -->
<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
<constructor-arg ref="hikariConfig" />
</bean>
the stak trace:

Tomcat does not completely supports Java EE, it is only a Servlet container (implements the Servlet and JSP specifications)
What is the difference between Tomcat, JBoss and Glassfish?)
If you application is using Java EE resources (e.g. EJB), you should not be able to run it using Tomcat.
I suggest the creation of a new application from scratch using TomCat and then check if it runs, after that you can compare the configuration files to make sure that nothing from the Glassfish configuration was left behind.

For tomcat you should use and transaction_type should be "RESOURCE_LOCAL"

Exceptions during long remote execution via JMS based on Spring

I use Spring remoting via JMS like that:
Client
<bean id="requestQueue" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg value="request"/>
</bean>
<bean id="dispatcher"
class="org.springframework.jms.remoting.JmsInvokerProxyFactoryBean">
<property name="serviceInterface" value="x.Dispatcher"/>
<property name="connectionFactory" ref="connectionFactory"/>
<property name="queue" ref="requestQueue"/>
</bean>
Server
<bean id="requestQueue" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg value="request"/>
</bean>
<bean id="dispatcher" class="org.springframework.jms.remoting.JmsInvokerServiceExporter">
<property name="serviceInterface" value="x.Dispatcher"/>
<property name="service">
<bean class="com.brtel.btwp.dispatcher.DispatcherImpl"/>
</property>
</bean>
<bean class="org.springframework.jms.listener.SimpleMessageListenerContainer">
<property name="connectionFactory" ref="connectionFactory"/>
<property name="destination" ref="requestQueue"/>
<property name="concurrentConsumers" value="10"/>
<property name="messageListener" ref="dispatcher"/>
</bean>
And its work fine. But if method on server took's more that 30 serconds I have exceptions and server stops process any other requests.

Can you recomend how to avoid this situation? Thanks!

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>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- Enable Hibernate's automatic session context management -->
<property name="current_session_context_class">thread</property>
<!-- Enable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.EhCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">update</property>
<mapping resource="com/amakena/profile/mapping/Credentials.hbm.xml"/>
<mapping resource="com/amakena/profile/mapping/Profile.hbm.xml"/>

<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.
