Question

In my webapp which is deployed in tomcat environment, I have one spring configuration file which contains placeHolder, like ${myurl}. To replace the placeholder, I created applicationContext.xml in WEB-INF directory which contains a PropertyPlaceholderConfigurater bean and set its location to a properties file which also inside WEB-INF directory.

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="
http://www.springframework.org/schema/beans    
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="placeHolderConfigurer"
  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="location" value="WEB-INF/my.properties"/>
 </bean>
  <import resource="classpath*:META-INF/springFile1.xml"/>
</beans>

Then in web.xml, I specify the context:

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml
    </param-value>
</context-param>

In WEB-INF/my.properties
myurl=http://www.google.com

This is the springFile1.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans    
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

<bean id="placeholderConfig"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="placeholderPrefix" value="${" />
    <property name="placeholderSuffix" value="}" />
</bean>
<bean id="mycache" class="com.abc.MyURL"
    init-method="start" destroy-method="stop">

    <constructor-arg value="${myurl}" />
</bean>
</beans>

I keep getting the unparsed value ${myurl}

I tried to put properties file in classpath, absolute path, and WEB-INF, all result the same.

Any suggestions? Thanks.

Instead of listing the xml files in web.xml, try importing them in applicationContext.xml:

<import resource="classpath*:springFile1.xml"/>

Update: It appears you are redefining the placeholder configurer in the child xml, thus overriding the one from the parent, which specifies the target properties file. Remove the configurer declaration from the child xml.
