I want to use JNDI DataSource provided by Tomcat in Spring based application. I use Tomcat 7 pool. Tried to configure as described here.
Configured server.xml of Tomcat:
<GlobalNamingResources>
<Resource name="jdbc/ApsuserAtAzistst"
auth="Container"
type="org.apache.tomcat.jdbc.pool.DataSource"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:#10.0.153.10:1525:AZISTST"
username="APSUSER"
password="PASSWORDOFAPSUSER"
initialSize="1"
minIdle="1"
maxIdle="1"
maxActive="3"
maxWait="1000"
validationQuery="select 1 from dual"
jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer;org.apache.tomcat.jdbc.pool.interceptor.SlowQueryReport(threshold=1500)"
/>
</GlobalNamingResources>
created META-INF\context.xml with content:
<?xml version="1.0" encoding="UTF-8"?>
<Context>
<ResourceLink name="jdbc/ApsuserAtAzistst"
global="jdbc/ApsuserAtAzistst"
type="org.apache.tomcat.jdbc.pool.DataSource"/>
</Context>
and configured applicationContext.xml
<beans profile="dev,test,default">
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/ApsuserAtAzistst"/>
</bean>
</beans>
When I run applcation I receive an error:
SEVERE: Exception processing Global JNDI Resources
javax.naming.NamingException: Cannot create resource instance

Everything works when I change applicationContext.xml to:
<beans profile="dev,test,default">
<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
<property name="url" value="jdbc:oracle:thin:#10.0.153.10:1525:AZISTST"/>
<property name="username" value="APSUSER"/>
<property name="password" value="PASSWORDOFAPSUSER"/>
<property name="initialSize" value="1"/>
<property name="minIdle" value="1"/>
<property name="maxIdle" value="1"/>
<property name="maxActive" value="3"/>
<property name="maxWait" value="1000"/>
<property name="validationQuery" value="select 1 from dual"/>
<property name="jdbcInterceptors"
value="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer;org.apache.tomcat.jdbc.pool.interceptor.SlowQueryReport(threshold=1500)"/>
</bean>
</beans>
But I want to configure JNDI DataSource in Tomcat and use it.
The reason was that, I missed factory="org.apache.tomcat.jdbc.pool.DataSourceFactory". Right definition of resource must be
<GlobalNamingResources>
<Resource name="jdbc/ApsuserAtAzistst"
auth="Container"
type="javax.sql.DataSource"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:#10.0.153.10:1525:AZISTST"
username="APSUSER"
password="PASSWORDOFAPSUSER"
initialSize="1"
minIdle="1"
maxIdle="1"
maxActive="3"
maxWait="1000"
validationQuery="select 1 from dual"
jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer;org.apache.tomcat.jdbc.pool.interceptor.SlowQueryReport(threshold=1500)"
/>
</GlobalNamingResources>

I am working on a migration task where we are migrating the project from Websphere 6.1 to Websphere 7.0.0.39. Also upgraded JDK version from 1.5 to 1.6.
Actually one of the web project, uses spring and hibernate combination. The version of spring is 2.5.3. The spring context is initialized while bootstrapping i.e. # server startup.
So i am getting org.springframework.web.context.ContextLoader initWebApplicationContext Context initialization failed error while server startup.
I also did a google search on the below issue and found the jira SPR-4788 which says spring2.5 && ibm jdk6 will produce a NPE as below.
Stack Trace from the server startup log :

and maybe it is useful, when I debug my project it will go through this action
public String execute() {
if(firstName.equals("") || lastName.equals("")){
return ERROR;
}
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
Students student = new Students();
student.setFirstName(firstName);
student.setLastName(lastName);
StudentService service = (StudentService) ctx.getBean("StudentService");
service.addStudent(student);
return SUCCESS;
}
and when I use tx:annotations it wants to open the class JdkDynamicAopProxy and it cannot, but when I do not use tx:annotations, it will go to the StudentServiceImpl.addStudent(student)!!
I am so confused, it is my first project using j2ee, and I should deliver it by tomorrow morning :|, so any advise will greatly appreciated.
Your datasource bean should look like following
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://localhost:3306/enrollment"></property>
<property name="username" value="root"></property>
<property name="password" value="root"></property>
</bean>
Note you were missing driverClassName property in basic data source.
Using: Jboss 7.1.1, Hibernate 3.6.9, Spring 3.0.1.
I tried out to switch from Spring Transaction Manager:
<bean id="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
<property name="dataSource" ref="dataSource" />
</bean>
to Jboss Transaction Manager:
<!-- search for transaction managers -->
<tx:jta-transaction-manager/>
Using org.springframework.orm.jpa.JpaTransactionManager all works fine but if I remove "transactionManager" bean and added "" I get following error:
javax.persistence.TransactionRequiredException: no transaction is in progress
I found following in the server log:
08:40:58,382 INFO [org.hibernate.transaction.TransactionFactoryFactory] (MSC service
thread 1-1) Using default transaction strategy (direct JDBC transactions)
08:40:58,383 INFO [org.hibernate.transaction.TransactionManagerLookupFactory] (MSC
service thread 1-1) No TransactionManagerLookup configured (in JTA
environment, use of read-write or transactional second-level cache is not
recommended)
What that means? Does my application using java:jboss/TransactionManager now or not? Do I have to configure something on Jboss?

Thanks everybody!
Maybe this might help: http://thejavablog.wordpress.com/2010/11/26/java-lang-unsupportedoperationexception-the-user-must-supply-a-jdbc-connection/ , it basically says that there's something missing from persistence.xml (<provider>org.hibernate.ejb.HibernatePersistence</provider> or maybe hibernate.connection.provider_class-property ?), and Hibernate's ConnectionProviderFactory chooses to create a UserSuppliedConnectionProvider, which has getConnection defined as such:
public Connection getConnection() {
throw new UnsupportedOperationException("The user must supply a JDBC connection");
}
I also compared this with one of our own Hibernate/JPA -setups that works just fine with C3PO, and the only differences I spotted were that we pass some more properties to c3p0.ComboPooledDataSource and some properties to org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter when defining EntityManagerFactory in the Spring configuration xml:
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="false" />
<property name="generateDdl" value="false" />
<property name="databasePlatform" value="${jdbc.dialectClass}" />
</bean>
</property>
But I doubt that could be it. There are no properties defined in our persistence.xml (at all).
I am getting Following Exception while configuring the Connection Pool in Tomcat
This is Context.xml

Nothing complex here - you have mysql configured, but the jdbc driver for mysql either you never installed or never placed in the classpath.
Ignore/disable spring, hibernate, connection pools and just try this java code in a jsp or whatever.
Class.forName("com.mysql.jdbc.Driver");
Until that works (eg file is in class path), you will continue to have sadness
You must do the following steps:
1) Configuration of Spring beans
--------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="true" />
<property name="generateDdl" value="true" />
<property name="database" value="MYSQL" />
<property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect" />
</bean>
</property>
</bean>
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"
scope="singleton">
<property name="jndiName" value="jdbc/jpaExamples" />
<property name="resourceRef" value="true" />
</bean>
<bean id="jpaTemplate" class="org.springframework.orm.jpa.JpaTemplate">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
<!-- Definition of your beans -->
</beans>
2) Definition of DataSource resource in web-xml:
------------------------------------------------
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/jpaExamples</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
3) Definition of Resource in Context of server.xml
--------------------------------------------------
<Context docBase="WebServiceRequestPersistence_Web3" path="/WebServiceRequestPersistence_Web3" debug="5" reloadable="true" crossContext="true" source="org.eclipse.jst.jee.server:WebServiceRequestPersistence_Web3">
<Resource
name="jdbc/jpaExamples"
auth="Container"
type="javax.sql.DataSource"
maxActive="100"
maxIdle="30"
maxWait="10000"
username="myUsername"
password="myPassword"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/jpaExamples"
/>
</Context>
4) Copy of JDBC driver jar into lib of Apache Tomcat 6
------------------------------------------------------
Copy your MySQL Java connector (for example: mysql-connector-java-5.1.6.jar) in the lib sub-directory of Apache Tomcat 6 installation.
If you are using MyEclipse and you are trying to run it from MyEclipse Tomcat;
Go to preferences (Window > Preferences), then Servers > Integrated Sandbox > MyEclipse Tomcat > Paths
Under prepend to calsspath, add the jar.
