Based on your information, it need your check on your oracle jdbc connection first, especially for below part:
<!-- declare datasource -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:#localhost:1521:orcl21"/>
<property name="username" value="c##gss_pos" />
<property name="password" value="sys" />
</bean>
You need ensure you can connect to your Oracle DB via the localhost:1521:orcl21 with proper user and password.

Can you also use the latest JDBC driver? You are using 11.2.0.4. Try using 21.5.0.0 or 19.14.0.0. Check out OTN page.

Error creating bean with name 'emailController'

Image of error I am receivingHello I am new to sending emails with Spring MVC. I am taking contact information in from a form and I want to be updated via email every time a new contact has been added to the database of contacts. taking in all the form parameters is working and I am able to add them to the database, but when trying to generate the email to send I am getting an Error creating bean exception. This seems to only happens when I add #Autowired to the JavaMailSender Object that I am creating in my controller. If I do not add #Autowired I get a null pointer exception probably because no object is being generated for the mail sender. Can anyone please help me how to figure this out?
I am including the code and XML files to hopefully get some insight.

I am trying to have the email send after the contact Object is added to the database. If I take #autowired off it returns a null pointer exception as if it's generating an object for sending the email.

Add below dependency in your pom and remove others I defined below should work
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
and remove below:
<!-- Java Mail Dependency -->

</dependency>

STEP2 : move out your mail properties in application.properties instead of servlet xml.

spring.mail.port=587

Error in database connection

I have been working on a project, which is a simple Spring, Hibernate, JSF, MySQL integration; and I run it on Eclipse. The aim of the program is to add a Person(id, first name, last name, gender, age etc.) database on MySQLWorkbench and run it on server. I used Spring4, Hibernate4, Primefaces 5.0.2 and Eclipse Luna as tools.And I constructed the project as maven.
When I run the program on main, I want to see that a new Person is included in my table.
I used "GRANT ALL ON" and "FLUSH PRIVILEGES" commands for the user I have created, on terminal and received "Query OK" message.
Despite specifying username and password on necessary files, I cannot add a new record to my table.My Project structure is as follows:
And other files are:

Is there an extra step to achieve this database connection?
Or what is my mistake here?
Thanks for any help..

Probably your session is not getting flushed; might be a glitch in your configuration. It happens many a time for an instance if you have configured OpenSessionInView Filter it changes the default flush mode of your configuration. In the DAO layer check the flushMode session.getFlushMode()
The flush mode should not be NEVER or MANUAL
If the session is not getting flushed, you db will not be updated. You have to manually flush the session after your transaction by session.flush()
Also in the in configuration file just change the property to true from false & check <property name="connection.autocommit">true</property>

In addition, there is an completed error of bundle in felix.

Do you have this bundle installed in your container (Felix) as well?
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
<version>3.2.6.ga</version>
</dependency>
If not install it and then see what happens when you start your bundle.

For missing requirement [Bundle-number] osgi.wiring.package,
I added it as export-package in pom.xml, as mentioned below:
<Export-Package>
package for which error is thrown
</Export-Package>
and it worked.
So if it throws the above error even after declaring it as dependency, export-package may help

How to properly change spring configuation xml file to migrate from Hibernate 3 to Hibernate 4?

I am reading the book 'Pro Spring 3' and the author uses Hibernate 3 for an application.
The book's spring-config.xml is the following :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

My experimental spring-config.xml that tries to use Hibernate 4 is the following:

When I am trying to run the application using my own version of spring-config.xml I get the following error :

Am I doing the right code conversions here?

Update 2:
SpringHibernateSample.java :
import foo.bar.dao.ContactDao;
import foo.bar.domain.Contact;
import org.springframework.context.support.GenericXmlApplicationContext;
import java.util.List;
public class SpringHibernateSample {
public static void main(String[] args) {
GenericXmlApplicationContext ctx = new GenericXmlApplicationContext("spring-config.xml");
ContactDao contactDao = ctx.getBean("contactDao", ContactDao.class);
List<Contact> contacts = contactDao.findAll();
listContacts(contacts);
}
private static void listContacts(List<Contact> contacts)
{
System.out.println("");
System.out.println("Listing contacts without details:");
for (Contact contact: contacts)
{
System.out.println(contact);
System.out.println();
}
}
}

The problem is with the namespace reference for the xmnls:tx, if you look at your spring configuration for hibernate 4, you can see that the tx points to: http://www.springframework.org/schema/cache instead of http://www.springframework.org/schema/tx
It means that spring is looking for a cacheManager instead of a transactionManager
change xmlns:tx="http://www.springframework.org/schema/cache" to xmlns:tx="http://www.springframework.org/schema/tx" in the beans tag of the spring configuration file and it should work.

In your stack trace your can see :
Error creating bean with name 'org.springframework.cache.interceptor.CacheInterceptor#0'
The org.springframework.cache.interceptor package seems to be associated with AOP. So it's maybe related to your tag
<tx:annotation-driven/>
Try to remove it to see if you still have the error.
You can also try this :
<tx:annotation-driven transaction-manager="transactionManager" order="1"/>
And last, get the librairies directly from Spring and Hibernate, there is maybe a class in your librairies which cause the problem.
