[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3639) Need support for hierarchical beanRefFactory in ContextLoader
Need support for hierarchical beanRefFactory in ContextLoader
-------------------------------------------------------------
Key: JBSEAM-3639
URL: https://jira.jboss.org/jira/browse/JBSEAM-3639
Project: Seam
Issue Type: Feature Request
Components: Spring
Affects Versions: 2.1.0.GA
Reporter: Bob Shanahan
The Spring ContextLoaderListener allows loading of shared (by multiple wars), hierarchical
contexts as in the following sample web.xml config:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<context-param>
<param-name>locatorFactorySelector</param-name>
<param-value>classpath:com/i2i/services/beanRefFactory.xml</param-value>
</context-param>
<context-param>
<param-name>parentContextKey</param-name>
<param-value>i2i.services</param-value>
</context-param>
<context-param>
<param-name>webAppRootKey</param-name>
<param-value>i2i.webt</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
The Seam ContextLoader, however, only allows loading of one or more application contexts,
neither allowing single instances of shared contexts nor allowing for hierarchical
contexts (via setting of parent context key).
Attempts to overcome the limitation with the following <spring:context-loader>
config and beanRefFactory.xml fails as only the beans defined in the beanRefFactory are
directly visible to Seam.
<spring:context-loader>
<spring:config-locations>
<value>classpath:com/i2i/services/beanRefFactory.xml</value>
<value>/WEB-INF/beanRefFactory.xml</value>
</spring:config-locations>
</spring:context-loader>
