1. Modify the settings.xml file (in your .m2 directory)
   Comment out the appropriate context.config.class element depending on which configuration you want to start in.

   <settings>
   	<servers>
   		<server>
   			<id>myserver</id>
   			<username>ausername</username>
   			<password>apassword</password>
   		</server>
   	</servers>
   
   	<profiles>
   		<profile>
   			<id>databaseConfig</id>
   			<activation>
   				<activeByDefault />
   			</activation>
   			<properties>
   				<jdbc.url>
   					jdbc:hsqldb:file:${user.home}/tomcat/db/sail_database;shutdown=true
   				</jdbc.url>
   				<jdbc.driverClassName>
   					org.hsqldb.jdbcDriver
   				</jdbc.driverClassName>
   				<jdbc.username>ausername</jdbc.username>
   				<jdbc.password>apassword</jdbc.password>
   				<hibernate.dialect>
   					org.hibernate.dialect.HSQLDialect
   				</hibernate.dialect>
   				<db.vendor>hsqldb</db.vendor>
   			</properties>
   		</profile>
   		<profile>
   			<id>portalConfig</id>
   			<activation>
   				<activeByDefault />
   			</activation>
   			<properties>
   				<context.config.class>
   					net.sf.sail.webapp.spring.impl.SpringConfigurationImpl
   				</context.config.class>
   <!--
   				<context.config.class>
   					org.telscenter.sail.webapp.spring.impl.SpringConfigurationImpl
   				</context.config.class>
   -->			</properties>
   		</profile>
   	</profiles>
   
   	<activeProfiles>
   		<activeProfile>databaseConfig</activeProfile>
   		<activeProfile>portalConfig</activeProfile>
   	</activeProfiles>
   
   </settings>
   

add this to web.xml

     <context-param>
        <param-name>contextConfigClass</param-name>
        <param-value>org.telscenter.sail.webapp.spring.impl.SpringConfigurationImpl </param-value>
    </context-param>
....
	<init-param>
            <param-name>contextConfigClass</param-name>
            <param-value>org.telscenter.sail.webapp.spring.impl.SpringConfigurationImpl</param-value>
        </init-param>
