无法加载标签处理程序类“org.apache.struts2.views.jsp.ui.FormTag”对于标签“s:form”
如果我在 NetbeansIDE 中运行代码，它会显示以下错误：
org.apache.jasper.JasperException： /InvestorConfirm.jsp(53,12) PWC6032: 无法加载标签处理程序类 “org.apache.struts2.views.jsp.ui.FormTag” 对于标签“s:form”
我下载了struts2-core-2.0.11.jar文件，并搜索“struts2.views.jsp.ui.FormTag”，但找不到该类。
我该如何解决这个问题？
If I run my code in NetbeansIDE it shows the following error:
org.apache.jasper.JasperException:
/InvestorConfirm.jsp(53,12) PWC6032:
Unable to load tag handler class
"org.apache.struts2.views.jsp.ui.FormTag"
for tag "s:form"
I downloaded the struts2-core-2.0.11.jar file, and searched for "struts2.views.jsp.ui.FormTag", but couldn't find that class.
How can I resolve this issue?

要安装 Struts2，只需将 Struts2 JAR 文件（及其依赖项）放入
/WEB-INF/lib中。不要提取 JAR 文件并将其所有松散内容（TLD 文件？）散布在类路径上，正如一些糟糕在线教程（以 Roseindia.net 作为顶部）可能建议的那样。此异常即表示在类路径中找到了 TLD 文件，但在类路径中缺少关联的标记类。只有您这样做才会发生这种情况。根据 Apache 自己的 Struts2 文档清理类路径并重做。
顺便说一下，理论上这也可能是由于类路径中的 Struts2 版本不同造成的，但这不太可能，因为
FormTag的包在版本之间没有更改。To install Struts2, just put the Struts2 JAR file (and its dependencies) in the
/WEB-INF/lib.Do not extract the JAR file and spread all its loose contents (TLD files?) over the classpath as some poor online tutorials (with roseindia.net as topper) may suggest. This exception namely indicates that the TLD file is been found in the classpath, but that the associated tag class is missing in the classpath. This can only happen if you did so. Cleanup the classpath and redo according Apache's own Struts2 docs.
This can by the way in theory also be caused by having different Struts2 versions in the classpath, but this is unlikely as the package of
FormTaghas not been changed among versions.
