Question

我是学习“开放式CMS”并尝试理解它的新手，创建一些基于此CMS的基本网站。最新版本为8.0.3。我正在使用“opencms-7-development”doc进行培训（我在版本8中找不到相同的内容）。

我已经在源文件和配置文件中做了所有必要的准备工作来创建博客示例但是当我可以尝试查看任何页面时出现以下错误。有人知道我为什么要面对这个exception吗？

我不确定你想要实现什么，但是从阅读本文来看，似乎你想要输出文档的内容。在这种情况下，我宁愿坚持使用cms taglibrary而不是使用jstl。例如：

<cms:contentloop element="/blog/blogpost">
    <cms:contentshow element="Headline"/>
</cms:contentloop>

也许这有帮助。如果没有，您可能想要发布更多模板代码。

java.lang.NoSuchMethodError：org.opencms.jsp.I_CmsXmlContentContainer.hasMoreContent（）
