问题描述
我有一个应用程序的web.xml。
c>< cookie-config> c $ c>是，而旧版本（例如2.5）中不支持。 web.xml 已声明符合Servlet 2.5。
您有两个选项：
Redeclare web.xml 符合Servlet 3.0（隐含地也需要一个Servlet 3.0兼容的目标容器例如Tomcat 7，Glassfish 3，WebLogic 12等）。
如果无法升级，请使用自定义servlet过滤器或特定于容器的配置（例如Tomcat / JBoss中的 Valve ）;由于我从未真正使用它，因此无法回答WebLogic的问题，请考虑请求一个新的该部分的问题）。
I have the follwing web.xml for an application.
<?xml version="1.0"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <display-name>..</display-name> <description>..</description> <session-config> <cookie-config> <name>SESSIONDEBUG_JSESSIONID</name> </cookie-config> </session-config> </web-app>I get the following error upon deployment
Caused By: weblogic.descriptor.DescriptorException: VALIDATION PROBLEMS WERE FOUND problem: cvc-complex-type.2.4a: Expected element 'session-timeout@http://java.sun.com/xml/ns/javaee' instead of 'cookie- config@http://java.sun.com/xml/ns/javaee' here in element session- config@http://java.sun.com/xml/ns/javaee:<null>Not sure I fully understand the error. I see that it wants me to declare session-timeout in there. I'll give that a try..
解决方案The <cookie-config> is introduced in Servlet 3.0 and not supported in older versions such as 2.5. Your web.xml is declared conform Servlet 2.5.
You've 2 options:
Redeclare web.xml conform Servlet 3.0 (which implicitly also requires a Servlet 3.0 compatible target container such as Tomcat 7, Glassfish 3, WebLogic 12, etc).
If you can't upgrade, then forget it and solve it using a custom servlet filter or container-specific configuration (e.g. a Valve in Tomcat/JBoss; can't answer off top of head for WebLogic as I've never really used it, consider asking a new question for that part).
这篇关于weblogic中的web.xml验证由于cookie-config而导致错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
