Variables in Spring MVC servlet context?

Question

For Spring MVC project, I want to reduce errors and the amount of time when switching servers, paths, and etc in the servlet context.

Is there a way to store variables in the servlet context (i.e. servlet-context.xml)?

Example

VARIABLE is used to to switch the server url, user, and password in myDataSource

VARIABLE = "GOOGLE" // Server type: GOOGLE, YAHOO, BING. This will switch the server url, user, and password in myDataSource

<beans:bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <beans:property name="driverClassName" value="${jdbc.sqlserver.driver}" />
    <beans:property name="url" value="${jdbc.**VARIABLE**.url}" />
    <beans:property name="username" value="${jdbc.**VARIABLE**.user}" />
    <beans:property name="password" value="${jdbc.**VARIABLE**.pw}" />
</beans:bean>

Maybe I'm misunderstanding your question, but my answer to

is "No". These context configuration files are meant to be static.

What you should do instead is use Profiles. See here and here.
