Answer 1

In case you have already added the jar, check the location where you have added it. The usual way is to have a lib folder and add all your jars inside the lib folder. A word of caution here, do not forget to add all the jars of lib into the build path of your class. You can probably do it from the project explorer window itself by selecting each jar or can import the folder and its contents using the following hierarchy: Project -> Prefrences -> Build Path.

Answer 2

depending on the version of spring you are using, forinstance if its version 4X them avoid servlet-dispatcher declarations in your web.xml file!

Answer 3

Check that your maven dependencies are added in deployment path.

for doing that follow the following steps. 1. Go to properties of your project. 2. click on deployement assembly. 3. click add button on right. 4. then goto java build path. 5. then it will show maven dependency add it. 6. try again to run your project.

Answer 4

I know this is very late but maybe someone face with it.

i had this problem too.

my project was not a maven project.

i solved this by :

1- right click on project and select "properties".

2- select "Deployment Assembly".

3- click add button.

4- select "Java Build Path Entries".

5- click next and select all jars.

6- Finish .

Answer 5

I solved it in a straightforward way:

1. Go to Servers view.
2. Select your server and right click on "Clean..."
3. Rebuild application.

Answer 6

you can user very well localSessionFactory as there is no harm and can use sessionfactory like this
@Autowired private SessionFactory sessionFactory;

            @Override
            public void createSection(Section section) {
            sessionFactory.getCurrentSession().save(section);
            }              

            @Override
          public void deleteSection(Section section) {
             sessionFactory.getCurrentSession().delete(section);

             }

           @Override
           public Section findBySectionID(int id) {
            Query query = sessionFactory.getCurrentSession().createQuery("from Section                   
          where id = " + id);

            return (Section) query.list().get(0);

        }

And hibernate.cfg.xml.this is the xml to tell which and where are my model objects[java
model database mapping objects]

                 <?xml version='1.0' encoding='utf-8'?>
     <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate

   <hibernate-configuration>

        </hibernate-configuration>
