新手:从 Eclipse 在 JBoss 上运行 Struts2 时出现构建错误

发布于 2024-08-16 09:15:27 字数 9649 浏览 9 评论 0原文

我作为 .NET 开发人员已经有 8 年多了,我被安排参与一个 Java 项目,我正在努力加快步伐。我正在使用 Eclipse EE 3.5.1、JBoss 5.1 和 Struts 2.1.8.1(据我所知都是最新版本)。

我正在尝试创建一个具有简单登录和主页的新项目。但是当我从 Eclipse 运行我的项目时,出现以下构建错误:

I've been a .NET developer for over 8 years now and I've been placed on a Java project and I'm trying to get up to speed. I'm using Eclipse EE 3.5.1, JBoss 5.1, and Struts 2.1.8.1 (all the latest versions as AFAIK).

I'm trying to create a new project with a simple login and home page. But when I run my project from Eclipse I get the following build error:

听起来您的类路径中可能没有 Struts 2 JAR 文件。转到您的项目属性 -> Java 构建路径 ->库并确保必要的 Struts 2 JAR 文件都列在 Web 应用程序库下。

Sounds like you may not have the Struts 2 JAR files in your classpath. Go to your project properties -> Java Build Path -> Libraries and make sure the necessary Struts 2 JAR files are all listed under Web App Libraries.

您能否将您的 web.xmlstruts.xml 文件与 本教程(虽然使用的是 apache-tomcat 6 Server 而不是 JBoss)

即使评论中已经报了这个错误,教程确实有效。


我确实在这个Struts中找到了你的课程-2.1.8.tgz(参见docjar,如果Struts download中引用了struts download中的相关jar,这样应该就可以了。

WEB-INF
  lib
    struts-core2.1.8.jar

Could you compare your web.xml and struts.xml files to this tutorial (although it uses apache-tomcat 6 Server and not JBoss)

Even if this error has been reported in the comment, the tutorial does work.


I do find your class in thisStruts-2.1.8.tgz (see docjar), if the relevant jar in struts download is referenced in Struts download, this should be ok.

WEB-INF
  lib
    struts-core2.1.8.jar

好吧......我能够用一些简单的东西来调试主要错误,这对我来说现在有意义。我在 Eclipse Helios 上使用 Tomcat 插件和 Tomcat 7。很抱歉,如果这篇文章太明显了……我是新手。

错误以及我如何解决它们:-
1.严重:启动过滤器struts2时出现异常
java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

解决方案:我从 struts2 展示示例应用程序复制了所有 jar。可以在这里-> (必须删除,因为 stackoverflow 不允许我发布多个链接)
我将那场战争的 web-inf/lib 中的所有 jar 复制到我的 eclipse 项目的 web-inf/lib 中。仍然出现该错误....在检查时,我看到我以前的版本正在使用同一个服务器,我通过删除该服务器并在 eclipse 中重新创建来删除它...确保它没有引用我以前版本的 lib我当前的 lib 通过检查项目的运行时配置并在 web-inf/lib 之外创建了一个新的 lib 目录并将其设置在构建路径中。解决了那个特定的错误。

  1. 然后,出现了一些 spring 错误,例如未找到 SpringObjectFactory 之类的

解决方案:从我的 lib 中删除了所有 spring jar,例如 spring-beans、spring struts 插件等。解决了该特定错误。

  1. 然后出现了 xwork2 错误 -> com.opensymphony.xwork2.inject.DependencyException:
    和一些java运行时异常 解决

方案:您需要在web.xml中提及您的操作类包。感谢邮件存档...我可以解决它。链接-> http://mail- archives.apache.org/mod_mbox/struts-user/200908.mbox/%[电子邮件受保护]%3E
您需要在 web.xml 中提及您的操作包,如下所示:-

;
<过滤器名称>struts2
<过滤器类>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
<初始化参数>
<参数名称>actionPackages
<参数值>myapp.actions

就是这样。现在可以使用了。

Ok....I was able to debug major errors with some simple stuff which kind of makes sense to me now. I am using tomcat plugin on Eclipse Helios with Tomcat 7. Sorry if this post is too obvious....i am new to this.

Errors and how I resolved them:-
1. SEVERE: Exception starting filter struts2
java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

Solution: I copied all the jars from struts2 showcase example app. Available here -> (had to remove as stackoverflow dint allow me to post more than one link)
I copied all the jars in the web-inf/lib of that war to my web-inf/lib of eclipse project. Still got that error....on checking, I saw that the same server was being used by my previous versions which I removed by deleting that server and recreating in eclipse....made sure it did not reference my previous version's lib over my current lib by checking the runtime configuration for my project and created a new lib directory apart from my web-inf/lib and set it in the build path. Solved that particular error.

  1. Then, got some spring errors like SpringObjectFactory not found and stuff

Solution: Deleted all the spring jars from my lib like spring-beans, spring struts plugin etc. Solved that particular error.

  1. Then came the xwork2 errors -> com.opensymphony.xwork2.inject.DependencyException:
    and some java runtime exceptions

Solution: You need to mention your action classes package in web.xml. Thanks to a mail archive...i could resolve it. Link -> http://mail-archives.apache.org/mod_mbox/struts-user/200908.mbox/%[email protected]%3E
You need to mention your action package like this in your web.xml:-

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
<init-param>
<param-name>actionPackages</param-name>
<param-value>myapp.actions</param-value>
</init-param>
</filter>

Thats it. Its working now.
