Spring's ContentLoaderListener not found in the web-app but was found on the system classpath

Question

I am building a GWT app with Spring. I am having some issues to inject a dependency to one of my Servlets, so I am trying to narrow down what can be wrong.

First, when my app starts I get:

[WARN] Server class 'org.springframework.web.context.ContextLoaderListener' could not be found in the web app, but was found on the system classpath
[WARN] Adding classpath entry 'file:/home/macarse/.m2/repository/org/springframework/spring/2.5.6/spring-2.5.6.jar' to the web app classpath for this session For additional info see: file:/home/macarse/tpf/eclipse/plugins/com.google.gwt.eclipse.sdkbundle.2.0.4_2.0.4.v201006301309/gwt-2.0.4/doc/helpInfo/webAppClassPath.html [WARN] Server class 'org.apache.commons.collections.map.CaseInsensitiveMap' could not be found in the web app, but was found on the system classpath

Is that OK?

In my web.xml I have:

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath*:/META-INF/spring-presentation.xml, classpath*:/META-INF/spring-persistence.xml
    </param-value>
</context-param>

Is there a way to know if those two xml were loaded?

Answer 1

Scan your application startup logs. You should find logs telling you which context files it loaded in the following format (log pattern might differ based on your log config):

org.springframework.beans.factory.xml.XmlBeanDefinitionReader (315): Loading XML bean definitions from ServletContext resource [/META-INF/spring-presentation.xml]

org.springframework.beans.factory.xml.XmlBeanDefinitionReader (315): Loading XML bean definitions from ServletContext resource [/META-INF/spring-persistence.xml]
