JNDI (esup 4)

Le passage de JDBC vers JNDI se fait en modifiant trois fichiers.

1. Modifier le rdbm.properties :

   uportal-war/src/main/resources/properties/rdbm.properties

   ##### Maven Filtering
   ##### Use these settings to define DB connection settings in filters file: 
   hibernate.connection.jndiname=${environment.build.hibernate.connection.jndiname}
   ##### /filters/{env}.properties

2. Déclarer la ressource JNDI au niveau du serveur Tomcat :
   
   

   <TOMCAT_HOME>/conf/context.xml

   <Context path="/portail" docBase="/opt/webapps/uPortal" reloadable="false" crossContext="true">
       <WatchedResource>WEB-INF/web.xml</WatchedResource>
       <Resource name="jdbc/uPortalDB" 
           auth="Container" 
           type="javax.sql.DataSource"
           driverClassName="com.mysql.jdbc.Driver" 
           url="jdbc:mysql://localhost:3306/test" 
           username="root" 
           password="root" 
           validationQuery="select 1" 
           removeAbandoned="true"
           removeAbandonedTimeout="120" 
           maxWait="60" 
           maxActive="20" 
           maxIdle="10" />
   </Context>

   crossContext est nécessaire, par exemple pour le partage de session, mais tends à disparaître avec la norme portlet 2.0 (portlet développés sur la norme 1.0 ayant des servlets, permettant par exemple le téléchargement de fichiers)

3. Utiliser la ressource dans l'application. Modifier :
   
   

   uportal-war\src\main\resources\properties\contexts\datasourceContext.xml

   <bean id="PortalDb" parent="basePooledDataSource">
       <qualifier value="PortalDb"/>
       <property name="driverClassName" value="${hibernate.connection.driver_class}" />
       <property name="url" value="${hibernate.connection.url}" />
       <property name="username" value="${hibernate.connection.username}" />
       <property name="password" value="${hibernate.connection.password}" />
   </bean>

   
   En :
   
   

   uportal-war\src\main\resources\properties\contexts\datasourceContext.xml

   <bean id="PortalDb" class="org.jasig.portal.spring.beans.factory.MediatingFactoryBean">
       <property name="type" value="javax.sql.DataSource" />
       <property name="delegateBeanNames">
       <list>
           <value>PortalDb.JNDI</value>
           <value>PortalDb.direct</value>
       </list>
       </property>
   </bean>
   
   <bean id="PortalDb.JNDI" class="org.springframework.jndi.JndiObjectFactoryBean">
       <property name="jndiName" value="java:comp/env/${hibernate.connection.jndiname}" />
   </bean>
    
   <bean id="PortalDb.direct" class="org.apache.commons.dbcp.BasicDataSource" lazy-init="true">
       <property name="driverClassName" value="${hibernate.connection.driver_class}" />
       <property name="url" value="${hibernate.connection.url}" />
       <property name="username" value="${hibernate.connection.username}" />
       <property name="password" value="${hibernate.connection.password}" />
   
       <property name="maxActive" value="50" />
       <property name="maxIdle" value="10" />
       <property name="maxWait" value="1000" />
       <property name="removeAbandoned" value="true" />
       <property name="removeAbandonedTimeout" value="300" />
       <property name="logAbandoned" value="true" />
   </bean>
   
   

4. Configurer le fichier esup.properties :

   filters/esup.properties

   environment.build.hibernate.connection.jndiname=jdbc/uPortalDB

5. Redéployer l'application
