Deployment plan question

Question

I have the following code in my Spring applicationContext.xml -
<!-- WebLogic JNDI -->
     <bean id="dataSource"
          class="org.springframework.jndi.JndiObjectFactoryBean">
          <property name="jndiName"
               value="cyncssit" />
     </bean>
I would like to change the jndi name of the datasource based on the environment to which the app is deployed. I understand the weblogic deployment plan can only override properties in weblogic-specific deployment descriptors and not the properties in applicaton.xml, web.xml or any spring config files. I was wondering if there is a way to specify the jndi name of the datasource in weblogic-application.xml or weblogic.xml and refer to that name in my spring config file? Bottom line is that I need to override the datasource name during deployment. Any solutions would be greatly appreciated.
Thanks in advance!

Yes, You are right. Plan.xml cannot be used for this purpose...because it can be used only to alter J2EE/WebLogic Standard Deployment Descriptors.
<h2><font color=red>WORKAROUND</font></h2>This workaround requires some changes in your application...So u may not like it.
But as an Alternative option you can do the following:
To know more about "virtual-directories" please refer to: http://jaysensharma.wordpress.com/2010/03/29/virtual-directory-mapping-in-webapps/
<h3>Step1).</h3> Inside your Application *"WEB-INF/weblogic.xml"* Configure a Virutal-Directory mapping in your "weblogic.xml" like following:
<?xml version="1.0" encoding="ISO-8859-1"?>
   <weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90">
      <virtual-directory-mapping>
         <local-path>C:\DELETE\Spring_JNDI_Demo</local-path>
         <url-pattern>*.xml</url-pattern>
      </virtual-directory-mapping>
</weblogic-web-app>
<h3>Step2).</h3> Now Place your *"applicationContext.xml"* inside *"C:\DELETE\Spring_JNDI_Demo"* directory...so that whenever you want you can change it...(the JNDIName).
<h3>Step3).</h3> inside your *"WEB-INF/web.xml"* provide the mapping of context-param like below:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>SpringOne</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<font color=maroon> <param-value>applicationContext.xml</param-value></font><BR>
<font color=red><!-- NOTE: param-value is NOT "WEB-INF/applicationContext.xml" rather only "applicationContext.xml" --></font> <BR>
</context-param>
<servlet>
<servlet-name>SpringContextServlet</servlet-name>
<servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
</web-app>
<h3>Step4).</h3> Now Deploy your Application ...and then Later whenever you want to change the JNDI name ....Just you need to edit *"applicationContext.xml"* inside *"C:\DELETE\Spring_JNDI_Demo"* and then <font color=red><b>Redeploy the Application</b></font>
Following Working Sample is attached...Here: http://www.4shared.com/file/ewFN1ODj/Spring_JNDI_Demo.html you may want to try. The Sample Application is Tested in WLS10.3
