title: How to properly locate Spring Context property-placeholder?
body: <p>I am attempting to implement an outdated open-source Properties File Manager (<a href="https://github.com/Confluex/Zuul/wiki" rel="nofollow noreferrer">https://github.com/Confluex/Zuul/wiki</a>) with a Mule Test Application in MuleSoft's Anypoint Studio platform. This appears to require the Spring Context Schema, but the project cannot locate it. It continually states there is no 'context:property-placeholder'. I feel a versioning error may be the problem. Here is my attempt: </p>
  <pre><code>&lt;mule 
      xmlns=&quot;http://www.mulesoft.org/schema/mule/core&quot; 
      xmlns:context=&quot;http://www.springframework.org/schema/context&quot;
      xmlns:spring=&quot;http://www.springframework.org/schema/beans&quot;
      xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot;
      xmlns:zuul=&quot;zuul-spring-client-1.5.1&quot;
      xsi:schemaLocation=&quot;
  http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd

  zuul-spring-client-1.5.1 zuul-spring-client-1.5.1.xsd&quot;&gt;
  
  
          &lt;context:property-placeholder properties-ref=&quot;MuleMeetZuul&quot; /&gt;
      
  &lt;/mule&gt;
