How to use Spring Managed Hibernate Session in Seam?

Question

Most recent project I working where I trying to use Spring (3.1.1.RELEASE) Managed Hibernate Session into Seam (2.3.0.Final).

In JBoss Seam Documentation where they explain How to use Seam Managed Hibernate Session in Spring. But our requirement is invert than the documentation.

I got another solution Using Spring PlatformTransactionManagement but my requirement is use Spring Managed Hibernate Session in Seam. I don't want to use Seam manage Hibernate Session/Hibernate Entity Manager/Transaction. Only want to use Seam manage dependency injection to inject Spring bean into Seam manage bean via seam @In not Spring @Autowire.

If anybody faces such type of challenge please either help to configure Seam components.xml & Spring applicationContext.xml or provide me guide line to overcome this.

Answer 1

First Configure applicationContext.xml as usually you configured:

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <!-- hibernate Properties Here -->                     
</bean>
<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven/>

Then Configure components.xml as following:

<core:init debug="true" transaction-management-enabled="true" />
<spring:context-loader config-locations="classpath*:/META-INF/spring/applicationContext.xml"/>
<core:manager concurrent-request-timeout="500" conversation-timeout="120000" conversation-id-parameter="cid" parent-conversation-id-parameter="pid" />
<persistence:managed-hibernate-session name="hibernateSession" auto-create="true" session-factory="#{sessionFactory}"/>
<spring:spring-transaction platform-transaction-manager="#{transactionManager}"/>

Its very much easy to interact Spring(3.1.1.RELEASE) with Seam (2.3.0.Final) but never forget to configure web.xml for seam.

<listener>
    <listener-class>org.jboss.seam.servlet.SeamListener</listener-class>
</listener>

<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

<servlet>
    <servlet-name>Seam Resource Servlet</servlet-name>
    <servlet-class>org.jboss.seam.servlet.SeamResourceServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Seam Resource Servlet</servlet-name>
    <url-pattern>/resource/*</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>Seam Filter</filter-name>
    <filter-class>org.jboss.seam.servlet.SeamFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>Seam Filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

<login-config>
    <auth-method>BASIC</auth-method>
</login-config>

<session-config>
    <session-timeout>10</session-timeout>
</session-config>

<welcome-file-list>
    <welcome-file>index.html</welcome-file>
</welcome-file-list>

For facelets your should add variable resolver in faces-config.xml

<application>
    <variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>
</application>

Better to download Seam-2.3.0.Final. Uzip it, inside examples\spring\ folder you will got your desired configuration
