Subject [jira] Commented: (GERONIMO-3954) Allow overriding the value of an <env-entry/> from within deployment plans
Date Thu, 26 Mar 2009 10:19:53 GMT

    [ https://issues.apache.org/jira/browse/GERONIMO-3954?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12689421#action_12689421

David Jencks commented on GERONIMO-3954:
----------------------------------------

Also I'm not sure if openejb is using the geronimo env-entry builder -- this change may not
affect openejb.

> The provider or assembler of an JavaEE application can define environment entries inside
the standard deployment descriptor files like ejb-jar.xml or web.xml with
> {code:xml}
> <env-entry>
>     <description>Some crucial variable!</description>
>     <env-entry-name>someVariable</env-entry-name>
>     <env-entry-type>java.lang.String</env-entry-type>
>     <!--env-entry-value>content of string</env-entry-value-->
> </env-entry>
> {code}
> Currently, the deployer of this application needs to modify the standard deployment descriptor
to set the environment entry to a value. This is a problem, if e.g. the archive containing
the descriptor file was signed by the provider and is supposed to be used unmodified. It would
be a major improvement, if the Geronimo deployment plans would allow setting or overriding
the values of these entries.
> This seems to have been the case in previous versions of Geronimo. On August 24th, 2003
the schema incubator-geronimo/modules/core/src/schema/geronimo-ejb-jar.xsd contained the following
elements:
> {code:xml}
> [...]
> <xsd:element name="env-entry">
>   <xsd:annotation>
>     <xsd:documentation>
>       Configuration for an environment entry.  Normally an env-entry
>       is fully configured by the assembler in the standard ejb-jar.xml
>       deployment descriptor.  However, the deployer can specify a
>       value here if there was no value specified in ejb-jar.xml, or
>       if the deployer wants to override the value specified there.
>     </xsd:documentation>
>   </xsd:annotation>
>   <xsd:complexType>
>     <xsd:sequence>
>       <xsd:element ref="env-entry-name" minOccurs="1" maxOccurs="1"/>
>       <xsd:element ref="env-entry-value" minOccurs="1" maxOccurs="1"/>
>     </xsd:sequence>
>   </xsd:complexType>
> </xsd:element>
