Question

我开始将Tomcat 6中的wep应用程序更新为当前版本的Tomcat（7-27）。当我使用以下错误消息启动服务器时出现问题：

com.qnamic.railopt.web.security.portlet.PortletSecurityFilter类实现了接口javax.portlet.filter.PortletFilter：

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.security.Principal;

import org.apache.log4j.Logger;

import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;

public class PortletSecurityFilter implements ActionFilter, EventFilter, RenderFilter, ResourceFilter {

ActionFilter实现了javax.portlet.filter.PortletFilter

某些依赖项具有范围＆＃34;提供＆＃34;并且不包括在战争中（因为tomcat没有使用它们）！

我的portlet.xml的一部分

<filter>
<filter-name>PortletSecurityFilter</filter-name>

</filter>

其他依赖项可在父项目中找到：

PC-API-2.2.0-GA.jar

PC-portlet的2.2.0-GA.jar
PC-MC-2.2.0-GA.jar
WCI-WCI-2.1.1-GA.jar
WCI-tomcat7-2.1.1-GA.jar

当我调试代码时 org.gatein.pc.portlet.impl.jsr168.ClassInstanceLifeCycle.create（...）它停在第二行

Class clazz = classLoader.loadClass(className);
if (expectedClass.isAssignableFrom(clazz)) {
    Class<? extends T> castedClass = clazz.asSubclass(expectedClass);
    Constructor<? extends T> ctor = castedClass.getConstructor();
    instance = ctor.newInstance();
}
else  {
    String msg = "Cannot create " + type + " with class " + className + " because it does not   implement the expected interface " + expectedClass.getName();
    throw new PortletInitializationException(msg);
}

我的建议首先是类加载器存在问题，但它不应该是，因为第一行正确加载了类PortletSecurityFilter。正如预期的那样，期望的类是javax.portlet.filter.PortletFilter。为什么班级不能分配？

感谢您的帮助！

我必须承认，我不知道您用来解决此问题的GateIn的确切版本是什么，但无论如何，我可以通过简单地保留（故意）portlet来重现GateIn-3.2.0.Final-tomcat7的这个问题。我的war文件的WEB-INF / lib目录中的api-2.0.jar。我可以得到类似的东西：

我可以通过简单地从我的webapp的WEB-INF / lib中删除portlet-api-2.0.jar来修复它（或者在提供的maven中定义这种依赖关系）。这只是因为jar文件已经在tomcat / lib中，所以Portlet Container引用了从Tomcat的公共ClassLoader加载的类javax.portlet.filter.PortletFilter，而你的Filter实现了类javax.portlet.filter。已经从webapp的ClassLoader（来自WEB-INF / lib）加载的PortletFilter，即使这两个类的FQN相等，它们也不被视为同一类，因为expectedClass.isAssignableFrom（clazz）返回false。

LifeCycle错误 - 未实现正确的接口javax.portlet.filter.PortletFilter
