Activating Spring Profile active JVM arguments in GWT hosted mode - spring

Question

I have a spring profile configuration as shown below
<beans profile="dev">
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${db.driverClassName}" />
<property name="jdbcUrl" value="dfgdfg" />
<property name="user" value="${db.username}" />
<property name="password" value="${db.password}" />
</bean>
</beans>
<beans profile="prod">
<jee:jndi-lookup id="dataSource" jndi-name="jdbc/Test"/>
</beans>
I am trying to make one of this active via the VM argument -Dspring.profiles.active="dev" . This works in Tomcat and so does the context-param route in Hosted mode via the gwt-maven-plugin but I can't get the VM arguments to work . I tried mvn -Dspring.profiles.active="dev" gwt:run also tried to pass -Dspring.profiles.active="dev" via the VM arguments under the JRE tab in run configurations along with the goal gwt:run . I also tried the environment tab and even -Dspring.profiles.active=dev but the NoSuchBeanDefinitionException doesn't budge . Is this because of the limited capability of the embedded server ?

No, simply gwt:maven plugin is kind of strange and it doesn't pass system properties to the launched JVM instance, and the only way to pass parameters is to put it into <extraJvmArgs> in plugin configuration e.g. in your case you have to add following to the configuration tag of gwt plugin:
<extraJvmArgs>-Dspring.profiles.active=dev</extraJvmArgs>
God knows why this works only this way, I wish there were some other normal way.
