我struts2-jquery-plugin-3.5.1-sources.jar在 Struts 2 中使用我将 jar 文件放在 lib 目录中，并将其添加到构建路径中。

我在 JSP 中做了一个条目

<%@ taglib prefix="sj" uri="/struts2-jquery-tags" %>

但它显示一个错误Can not find the tag library descriptor for "/struts2-jquery-tags"

当我运行应用程序时，它显示为

SEVERE: Exception starting filter struts2
Unable to load bean: type:org.apache.struts2.views.TagLibrary class:com.jgeppert.struts2.jquery.views.JqueryTagLibrary - bean - jar:file:/D:/eclipse-indigo/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/Fundation/WEB-INF/lib/struts2-jquery-plugin-3.5.1-sources.jar!/struts-plugin.xml:27:125

有同样的问题。

尝试

<%@ taglib prefix="sj" uri="/struts-jquery-tags" %>

代替

<%@ taglib prefix="sj" uri="/struts2-jquery-tags" %>

你应该使用 struts-jquery-plugin.jar

而不是 struts2-jquery-plugin-3.5.1-sources.jar 因为它包含源文件
