[jboss-dev-forums] [Design of POJO Server] - Missing feature in EJB2 ContainerConfiguration merge

[adrian@jboss.org]

In the old EJB2 container configuration, you could do something like this
which is an extension of the container configuration without changing its name


  | <container-configurations>
  |   <container-configuration>
  |     <container-name>Standard Stateless SessionBean</container-name>
  |     <depends>test:name=Test</depends>
  |   </container-configuration>
  | </container-configurations>
  | 

This is the old code (note the comment).


  |             Element conf = (Element)iterator.next();
  |             String confName = getElementContent(getUniqueChild(conf,
  |                     "container-name"));
  |             String parentConfName = conf.getAttribute("extends");
  |             if (parentConfName != null && parentConfName.trim().length() == 0)
  |             {
  |                parentConfName = null;
  |             }
  | 
  |             // Allow the configuration to inherit from a standard
  |             // configuration. This is determined by looking for a
  |             // configuration matching the name given by the extends
  |             // attribute, or if extends was not specified, an
  |             // existing configuration with the same.
  |             ConfigurationMetaData configurationMetaData = null;
  |             if (parentConfName != null)
  |             {
  |                configurationMetaData = getConfigurationMetaDataByName(parentConfName);
  |                if (configurationMetaData == null)
  |                {
  |                   throw new DeploymentException("Failed to find " +
  |                           "parent config=" + parentConfName);
  |                }
  | 
  |                // Make a copy of the existing configuration
  |                configurationMetaData =
  |                        (ConfigurationMetaData)configurationMetaData.clone();
  |                configurations.put(confName, configurationMetaData);
  |             }
  | 
  |             if (configurationMetaData == null)
  |             {
  |                configurationMetaData =
  |                        getConfigurationMetaDataByName(confName);
  |             }
  | 
  |             // Create a new configuration if none was found
  |             if (configurationMetaData == null)
  |             {
  |                configurationMetaData = new ConfigurationMetaData(confName);
  |                configurations.put(confName, configurationMetaData);
  |             }
  | 

This isn't working in the new metadata because the the wrapper
only looks at the extends attribute.
