我有我的配置:

<context:property-placeholder location="classpath:idm.properties" />

<bean id="idmPropertyHolder" class="fi.utu.resurssitilaus.idm.IdmPropertyHolder">
   <property name="url" value="${idm.url}" /> 
    <property name="user" value="${idm.user}" />
    <property name="password" value="${idm.password}" />
    <property name="proxyHost" value="${http.proxyHost}" />
    <property name="proxyPort" value="${http.proxyPort}" />
</bean>

我收到了错误

Servlet容器集的类路径是什么？

据我了解,涉及三个组成部分.在该JAR文件lib的Servlet容器的目录,然后在类的WEB-INF/classes在和JAR文件WEB-INF/lib的目录.libServlet容器目录中的类被添加到系统类路径中,动态类路径包括lib目录中的JAR文件和目录中的类classes.

什么是动态类路径集？动态类路径是指向所有目录下的所有目录WEB-INF还是包含所有单个类和JAR文件WEB-INF/lib,WEB-INF/classes或者只指向两个目录WEB-INF/classes和WEB-INF/lib？说我有一个名为目录foo中WEB-INF包含bar.properties.现在bar.properties也是在班级路径？
