JdbcHttpSessionConfiguration messes my Bean Constants

I am using spring MVC 4.2 I have this code in my app-context.xml
<bean id="beanConstants" name="beanConstants" class="com.my.web.controller.BeanConstants">
<property name="dbProplocation" value="/my/database.properties" />
<property name="extractDbProplocation" value="/my/extract.database.properties" />
<property name="cssLocation" value="uncompiled" />
<property name="enableSuspensionPollingStr" value="false" />
</bean>
<!-- JDBC Session Config -->
<bean class="org.springframework.session.jdbc.config.annotation.web.http.JdbcHttpSessionConfiguration"/>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="${hibernate.connection.url}" />
<property name="username" value="${hibernate.connection.username}" />
<property name="password" value="${hibernate.connection.password}" />
</bean>
Now this all worked fine until I added the JdbcHttpSessionConfiguration bean. If I take that line out, it works. otherwise I get this:
Caused by: java.lang.IllegalArgumentException:
Could not resolve placeholder 'hibernate.connection.url' in string value "${hibernate.connection.url}"
I am trying to save the sesstion info in the DB. Why is this doing this? What has one got to do with the other?

Searchpath with Postgres does not work with Spring/DBCP datasource

Postgres extensions are installed in public schema.
Set the search path for the app-specific schema on the DBCP datasource the following way:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" primary="true">
<property name="driverClassName" value="org.postgresql.Driver"/>
<property name="url" value="jdbc:postgresql://myhost:myport/${db.gos_app.database}?searchpath=mySchema,public;?ApplicationName=${app.name}"/>
<property name="connectionProperties" value="currentSchema=mySchema;"/>
<property name="username" value="user"/>
<property name="password" value="pw"/>
<property name="defaultAutoCommit" value="false"/>
<property name="maxActive" value="6" />
</bean>
But somehow I cannot use extensions installed in this public schema without qualifying them like "public.hstore".

Found the solution - JDBC driver does not know the searchpath property in the URL. But this has been nowhere reported :-(
Instead currentSchema is given to driver which is then mapped to native Postgres searchpath (thus probably overwriting the default one there with public included). Not intuitive!
So the solution looks like this:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" primary="true">
<property name="driverClassName" value="org.postgresql.Driver"/>
<property name="url" value="jdbc:postgresql://myhost:myport/${db.gos_app.database}?ApplicationName=${app.name}"/>
<property name="connectionProperties" value="currentSchema=mySchema,public;"/>
<property name="username" value="user"/>
<property name="password" value="pw"/>
<property name="defaultAutoCommit" value="false"/>
<property name="maxActive" value="6" />

Connecting Java Web Application to Oracle Database

<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName"
value="????????????????????" />
<property name="url"
value="???????????????????????"/>
<property name="username" value="root" />
<property name="password" value="" />
</bean>
I am not able to figure out what should go in driver class name value and url vale. I have downloaded Oracle sql developer and oracle 11 g.But i am not sure how to configure it to my java application

Driver class name:- oracle.jdbc.driver.OracleDriver
URL :- jdbc:oracle:thin:#(hostname):(port number):(database name)
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName"
value="oracle.jdbc.driver.OracleDriver" />
<property name="url"
value="jdbc:oracle:thin:#(hostname):(port number):(database name)"/>
<property name="username" value="root" />
<property name="password" value="" />
</bean>

Your qustion is not clear if you are using Spring framework there are two type of
Data source handling technique
Method 1 you need to configure data source in your application server
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:jboss/datasources/OracleDS" />
<property name="cache" value="false"/>
<property name="lookupOnStartup" value="false"/>
<property name="proxyInterface" value="javax.sql.DataSource"/>
</bean>
Method 2
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:#127.0.0.1:1521:OMQA" />
<property name="username" value="root" />
<property name="password" value="password" />
</bean>

Use property file's property in spring mvc configuration servlet xml

I use following line of code to read config.properties file in my spring mvc configuration servlet xml file.
<context:property-placeholder location="file:///${config.properties}" />
config.properties contains a property say: propertyName = propertyValue
I want to use this propertyName's value in spring mvc configuration servlet xml file.

Here is an example of configuring as pool with properties taken from a properties file
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:#${database.url}" />
<property name="username" value="${database.username}" />
<property name="password" value="${database.password}" />
<property name="validationQuery" value="SELECT 1 FROM DUAL" />
<property name="testWhileIdle" value="true" />
<property name="timeBetweenEvictionRunsMillis" value="300000" />
<property name="numTestsPerEvictionRun" value="6" />
<property name="minEvictableIdleTimeMillis" value="1800000" />
<property name="initialSize" value="3" />
<property name="maxActive" value="75" />
<property name="maxIdle" value="75" />
<property name="maxWait" value="5000" />
<property name="poolPreparedStatements" value="true" />
<property name="maxOpenPreparedStatements" value="100" />
</bean>
The property file contains there rows
database.url=localhost:1521:xe
database.username=dbusername
database.password=dbpassword

I guess you need to add
<context:property-placeholder location="file:///${config.properties}" />
to your servlet.xml file.

How do I add database pooling - Spring3, Hibernate, MySQL

Spring3, Hibernate, MySQL: I am working on my first project, can some one please show me how to change the following code to add database pooling? thanks
applicationContext-security-JDBC.xml
<beans:bean class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<beans:property name="driverClassName" value="${database.driver}" />
<beans:property name="url" value="${database.url}" />
<beans:property name="username" value="${database.user}" />
<beans:property name="password" value="${database.password}" />
</beans:bean>
jdbc.properties
database.driver=com.mysql.jdbc.Driver
database.url=jdbc:mysql://127.0.0.1/db_mytest
database.user=root
database.password=
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.show_sql=true
thanks.... again

I suggest you to use commons-dbcp. You have to download the jar and add it to the WEB-INF/lib directory (if not already included in your application server). This is your new applicationContext.xml with some default parameters that you should change as you wish:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${database.driver}" />
<property name="url" value="${database.url}" />
<property name="username" value="${database.username}" />
<property name="password" value="${database.password}" />
<property name="timeBetweenEvictionRunsMillis" value="300000" />
<property name="numTestsPerEvictionRun" value="6" />
<property name="minEvictableIdleTimeMillis" value="1800000" />
<property name="initialSize" value="3" />
<property name="maxActive" value="10" />
<property name="maxIdle" value="10" />
<property name="maxWait" value="5000" />
<property name="poolPreparedStatements" value="true" />
<property name="maxOpenPreparedStatements" value="100" />
</bean>
Hope this helps.

You don't specify what you are running your application on. Many application servers have their own connection pooling implementation that you can tap into. I've used Tomcat's DBCP in the past - was quite easy to set up.
