i have a web.xml with these 2 servlet:
<servlet>
<servlet-name>ApplicationContextFactory</servlet-name>
<servlet-class>com.bamboo.common.factory.ApplicationContextFactory</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
AND
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
I need to use these bean declared on the ApplicationContextFactory:
<bean id="**catalogFacadeTarget**" class="com.bamboo.catW3.business.impl.CatalogFacadeImpl">
<property name="categoryDAO"><ref local="categoryDAOTarget"/></property>
<property name="containerDAO"><ref local="containerDAOTarget"/></property>
<property name="productDAO"><ref local="productDAOTarget"/></property>
<property name="productOptionDAO"><ref local="productOptionDAOTarget"/></property>
<property name="productStatusDAO"><ref local="productStatusDAOTarget"/></property>
<property name="userDAO"><ref local="userDAOTarget"/></property>
</bean>
in the dispatcher-servlet like this:
<bean name="welcome"
class="com.bamboo.catW3.business.impl.Welcome">
<property name="successView">
<value>welcome</value>
</property>
<property name="catalogFacadeImpl"><ref local="**categoryDAOTarget**"/> </property>
</bean>
Is it posible some how? Thank you!
You can't share contexts between servlets.
If you need to share beans, then you need to move the shared beans out of the ApplicationContextFactory servlet's context and into the root webapp context, using a ContextLoaderListener declared in web.xml. Both servlets will then be able to use the beans defined in that root context.
(I'd give you a link, but springsource.org seems be down at the moment).

This question is about Java config in Spring. Is it possible to replace the following declaration in Java code.
<servlet>
<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/secure-app-context.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
Where secure-app-context.xml
<beans xmlns="http://www.springframework.org/schema/beans"
...
http://www.springframework.org/schema/aop/spring-aop-3.1.xsd">
<aop:aspectj-autoproxy />
<mvc:annotation-driven>
<mvc:message-converters register-defaults="false">
<bean class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter" />
<bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
</mvc:message-converters>
</mvc:annotation-driven>
<context:component-scan base-package="com.abc.secure.service" />
<bean id="securityAspect" class="com.abc.secure.service.Secure" />
</beans>
You can very well do it by using WebApplicationInitializer(you dont need web.xml in this case)
Please see the post below:
How to configure Spring MVC with pure Java-based configuration?
I am using #Transactional (org.springframework.transaction.annotation) at the service method from where I call the DAO layer to fetch data from DB.
However, I am getting following error
org.hibernate.HibernateException: No Session found for current thread
on
sessionFactory.getCurrentSession()
I have added package scanning to different files as suggested by other posts.Still unable to get the error.
Please help.Thanks a million in advance.
Following are the files I have used.
applicationContext.xml
<mvc:annotation-driven />
<context:annotation-config/>
<context:component-scan base-package="com.BASE_PCKG"></context:component-scan>
spring-servlet.xml
<mvc:annotation-driven />
<context:component-scan base-package="com.BASE_PCKG.SUB_PCKG.web"></context:component-scan>
Web.xml
...
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/applicationContext.xml</param-value>
</context-param>
....
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Also I have configured the transaction manager in applicationContext file as :
<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager" primary="true">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<tx:annotation-driven transaction-manager="txManager"/>
Add #Transactional on daoImpl class and Add transaction manager in configuration file:
<tx:annotation-driven/>
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
Calling the method via proxy would help and fix the issue.
Calling the same method from same class would not help transaction work.
The application works perfectly with the following config files:

I couldn't run spring security properly cause earlier spring-context.xml was the xml config file for dispatcher servlet for MVC. So I moved spring-context to contextConfigLocation. But then I had to provide something to dispatcher servlet.
My problem is that mvc-dispatcher-servlet.xml and spring-context is having same data. If I remove mvc-dispatcher its an error. If I don't place the contents of mvc-dispatcher in spring context then also error occurs.
Where am I going wrong in my understanding of concepts.
A few things:
Your web.xml looks correct
The InternalResourceViewResolver should only exist in your mvc-dispatcher-servlet.xml since it is directly related to MVC -- remove it from your spring-context.xml
You can have context:component-scan in both configuration files, but they should be scanning different packages. The one in your servlet xml will generally be component scanning your controller packages (and anything else directly related to MVC), and the one in your parent spring context xml will generally be scanning your services, DAOs, etc. In general, your component scan packages should be very specific; you should never point it towards the base package of your entire application!
You can remove context:annotation-config -- it is redundant if you have context:component-scan
Your MVC context should have only configuration related to MVC which generally includes ViewResolvers, FileUpload, PropertyFiles, Message/Theme Resolvers etc. Your applicationContext will have beans related to DAO, Service and other utils. The security file should have security configuration. To understand better and to know good/recommended practices, check out the spring greehouse code.
I am using spring framework in my project,
Here is part of my web.xml:
<servlet>
<servlet-name>SpringMvcServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/servlet-context.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringMvcServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<filter>
<filter-name>httpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>httpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<error-page>
<error-code>404</error-code>
<location>/system/404.html</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/system/500.html</location>
</error-page>
And configure:
<mvc:resources mapping="/system/**" location="/WEB-INF/pages/system/" />
But I find so many error in my log, some request like this:
POST /index.php
POST /notexists.html
They were not exists in my server, so will call "/system/404.html", but the mvc:resources don't accept POST method, so it will return 500 Error.
How to fix that? or work around?
Thanks
First of all: I think you abuse the ResourceHttpRequestHandler when you try to use it for POST requests. -- And I am not sure that every thing works correct if you made this handler to handle POST requests.
<mvc:resources /> configure an instance of class org.springframework.web.servlet.resource.ResourceHttpRequestHandler. This has the super class WebContentGenerator and this super class has a property Set<String> supportedMethods.
So all what you need to do is:
<property name="supportedMethods">
<list>
<value>GET</value>
<value>HEAD</value>
<value>POST</value>
</list>
</property>
Unfortunately this requires that you configure the ResourceHttpRequestHandler by hand instead of using <mvc:resources />
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="urlMap">
<map>
<entry key="/system/**" value="myResourceHandler" />
</map>
</property>
<property name="order" value="100000" />
</bean>
<bean id="myResourceHandler" name="myResourceHandler"
class="org.springframework.web.servlet.resource.ResourceHttpRequestHandler">
<property name="locations" value="/WEB-INF/pages/system/" />
<property name="supportedMethods">
<list>
<value>GET</value>
<value>HEAD</value>
<value>POST</value>
</list>
</property>
<!-- cacheSeconds: maybe you should set it to zero because of the posts-->
</bean>
I have not proved this configuration, I have just written it down from what the ResourceBeanDefintionParser does.
I develop a simple Spring application which is my university task. There are 3 configuration files: web.xml, core-context.xml, dispatcher-servlet.xml and 1 file with default properties which is called messages.properties and is located in /WEB-INF/ folder.
In my application I have the following configuration of ReloadableResourceBundleMessageSource and it works fine:
core-context.xml
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basenames" value="/WEB-INF/messages" />
<property name="useCodeAsDefaultMessage" value="true" />
</bean>
web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:core-context.xml</param-value>
</context-param>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
But it turned out that my task instruction says that I should configure ReloadableResourceBundleMessageSource bean in dispatcher-servlet.xml. The problem is that whenever I remove the above configuration from core-context.xml and put it in dispatcher-servlet.xml my locals are no longer displayed.
Could you explain to me why the problem occurs?
What is a difference between putting bean configuration inside core-context.xml and dispatcher-servlet.xml?
You have not posted your dispatcher-servlet.xml but I believe it is not being initialized by the spring container because it is not declared anywhere. If you must have another file called dispatcher-servlet.xml as you specify then you can just import it in your core-context.xml. This should solve your problem.
