I am new to spring-hibernate integration.
I am trying to enter data into database through jsp form, and I am getting a null pointer exception when the object is trying to persit.
I checked if the object is receiving values, and it does.
The reason I feel is because the dispatcher servelet is not allowing me to pass the value through.
Bellow is my dispatcher-servlet.
If any one can me show me the way to configure multiple controllers in dispatcher servelet it would be great.

Profile profile = new Profile();
profile.setFirstName(firstName);

myService.insert(profile);
}
}
Please help me figure out setting up Shiro annotations. Thank you.
Shiro has a Spring Boot example that uses Shiro's annotations on a controller. And a non-boot example too
Let me know how to initialize tiles from dispatcher and application context and if any changes required in web.xml,
this is my tiles.xml
<definition name="contact" extends="mainLayout">
<put-attribute name="title" value="Contact Manager" />
<put-attribute name="body" value="/WEB-INF/jsp/contact.jsp" />
</definition>
</tiles-definitions>
in application context i have used
<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
<property name="definitions">
<list>
<value>/WEB-INF/tiles.xml</value>
</list>
</property>
</bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="requestContextAttribute" value="requestContext"/>
<property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView"/>
</bean>
and dispatcher looks like this
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>
indexController</prop>-->
newController
<bean class="org.springframework.web.servlet.view.tiles2.TilesConfigurer" id="tilesConfigurer">
<property name="definitions">
<list>
<value>WEB-INF/tiles.xml</value>
</list>
</property>
</bean>
<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver" id="viewResolver">
<property name="viewClass">
<value>
org.springframework.web.servlet.view.tiles2.TilesView
</value>
</property>
In Dispatcher-Servlet
<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
<property name="definitions">
<list>
<value>/WEB-INF/tiles.xml</value>
</list>
</property>
</bean>
In web.xml use this code
<listener>
<listener-class>org.apache.tiles.web.startup.simple.SimpleTilesListener</listener-class>
</listener>
rest is not required for spring-tiles application, tiles.xml is depended on your requirement
I've cloned a spring-mvc project to my computer and trying to get it running using intelliJ. It seems, according to this that I need to establish an SQL connection. Do I need to download mysql to my computer, create an account and enter that information in my connection.XML file (seen below)?

Your conf file contains the definition for two different datasources, hsql and mysql. hsql is an in memory db.
Mysql is standalone database application.
yes to connect to the mysql source, you need to download mysql and set up users/schema.

this is the java file in which i am creating the entity manager
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
public class AbstractRepository {
#PersistenceContext
EntityManager entityManager;
}
so whenever i use this entity manager it gives null pointer exception
please help!
Your entity manager bean is called enetityManagerOne, but the variable is called entityManager. Maybe renamme your bean in your XML file:
<bean id="entityManager" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
Another solution could be you forgot the following bean declarations:
For the support for transaction:
<tx:annotation-driven/>
The support for parsing JPA annotations:
<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>
my application context was not on the correct place (src/main/resources). Now I put that there and its working.
Use this code in your dispatcher-servlet.xml
<bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">
<property name="persistenceXmlLocations">
<list>
<value>classpath*:META-INF/persistence.xml</value>
</list>
</property>
<property name="defaultDataSource" ref="dataSource"/>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitManager" ref="persistenceUnitManager"/>
<property name="persistenceUnitName" value="etray"/>
</bean>
<jee:jndi-lookup id="dataSource" jndi-name="java:/prateek" />
<!-- we plan to use JTA transactions and declare them using annotations -->
<bean id="transactionManager"
class="org.springframework.transaction.jta.JtaTransactionManager" />
<tx:annotation-driven transaction-manager="transactionManager" />
<!-- to inject instances of EntityManager using #PersistenceContext annotation -->
<bean
class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
it resolve my problem, hope it will help.

I have set up i18n to my web app using Spring MVC. It does not work.
When I click on the link:
de
nothing happens, only the address bar changes to
http://localhost:8080/wort/register.html?lang=de
but the displayed messages remain the same (english).
Obviously I have the messages_de.properties file next to the messages_en.properties file.
(there is no problem with the english messages' display.)
Do I miss something obvious?
