I am trying connect to external mySql database.
I get this error message on console:
Caused by: org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user 'adminbnnSIES'#'localhost' (using password: YES))
Caused by: org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Cannot open connection
This is how my applicationContext.xml looks like:

I couldnt find answer for my answer anywhere.
In my pom.xml i have this dependency:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.31</version>
</dependency>
On local connection I dont have such problem, here is my local bean setup:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/test" />
<property name="username" value="root" />
<property name="password" value="" />
</bean>
I think the problem should be with the host you are specifying there, "localhost" doesn't seem right for an external database.
This Openshift guide might be helpful:

The context is Java Spring MVC and Hibernate, in IntelliJ. For some reason, in the Spring MVC config file, "transaction-manager" is not recognized as a valid reference. See the red text below:
Any tips on how to resolve this?

I am trying to get the value of "value" attribute of second bean's property with name "jdbcUrl". I tried multiple xpath combinations, but the only one that works for me is (//#value)[4] which is not optimal at all because if someone changes order of properties, I will get the wrong value. Is there more safer way to do it using xPath?

get the value of "value" attribute of second bean's property with name "jdbcUrl"
That translates directly to
/*/*:bean[2]/*:property[#name="jdbcUrl"]/#value
That's XPath 2.0 syntax; if you're still using XPath 1.0 for some reason, then you can't use *:local; instead, either bind a prefix to the namespace http://www.springframework.org/schema/beans, or use *[local-name()="local"]
I would like set my Hibernate/JPA FlushMode to COMMIT, but in configuration file (applicationContenxt.xml is one of my files), i have a entityManager in my DAO, but i don't know how to set this in configuration file.

EDIT 1:
I tried the following in applicationContext.xml
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="jpaDialect">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect">
<property name="flushMode" value="COMMIT"/>
</bean>
</property>
Tomcat error:
aused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'flushMode' of bean class [org.springframework.orm.jpa.vendor.HibernateJpaDialect]: Bean property 'flushMode' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

... 53 more
SOLUTION:
After a lot of research, i found a solution. I setted the FlushMode in #PersistenceContext in my BasicDAO class. Look:
#PersistenceContext(type = javax.persistence.PersistenceContextType.EXTENDED,
properties = #PersistenceProperty(name="org.hibernate.flushMode", value="COMMIT"))
protected EntityManager entityManager;
This works fine. I removed all #Transactional annotation from my "find" functions, because with #Transactional the "COMMIT" are fired and flush too.
I am trying to access a property file containing db configurations in a Maven + Spring project.
I get following error:
Cannot load JDBC driver class '${db_driver}'
My Property file is placed in src/resources folder.
Below is the tag to load property files:
<bean id="dbPropertyReader"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="order" value="1" />
<property name="locations">
<value>classpath:${appenv.deployment}.properties</value>
</property>
</bean>
Following tag uses properties loaded:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="url" value="${db_url}" />
<property name="driverClassName" value="${db_driver}" />
<property name="username" value="${db_username}" />
<property name="password" value="${db_password}" />
</bean>
Below are contents of properties file:
#JDBC Properties
db_driver=com.mysql.jdbc.Driver
db_url=jdbc\:mysql\://hostname\:3306/xxx_dbxxx?useUnicode\=true
db_username=abcdefgh
db_password=ijklmnopq
db_removeabadoned=true
db_initialsize=1
db_maxactive=2
${appenv.deployment} is a VMArgument set as follows:
-Dappenv.deployment=development
I have checked, this value is getting populated properly.
I am getting following line in logs:
Found key 'appenv.deployment' in [systemProperties] with type [String] and value 'development'
Then after this I am also getting following:
Loading properties file from class path resource [development.properties]
But some how, the values are not getting loaded.

I assume you can configure DataSource in JBoss. Notice that you have to define its JNDI name in application server configuration. Once you have the name, simply replace your dataSource bean with:
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/some-name"/>
</bean>
or shortcut:
<jee:jndi-lookup id="dataSource" jndi-name="jdbc/some-name" expected-type="javax.sql.DataSource" />
