根据embedded jetty unable to parse web.xml when jsp jars present in classpath中的说明 我把以下启动代码放在一起,以嵌入模式启动jsp支持jetty,但仍然没有运气。我得到以下错误,下面提供了完整的堆栈:
java.lang.NoSuchMethodError: javax.servlet.jsp.tagext.TagAttributeInfo.<init>(Ljava/lang/String;ZLjava/lang/String;ZZLjava/lang/String;ZZLjava/lang/String;Ljava/lang/String;)V
有问题的类javax.servlet.jsp.tagext.TagAttributeInfo在org.mortbay.jasper.apache-jsp-8.0.9.M3.jar中定义。这个jar也是出于其他原因所需要的,引入了JasperInitializer类,JettyJasperInitializer的超类。
我怀疑使用jar org.mortbay.jasper.apache-jsp-8.0.9.M3.jar不建议用于jetty 9.2.10.v20150310。如果是这样 - 有什么选择? 我应该得到org.apache.jasper.servlet.JasperInitializer和javax.servlet.jsp.tagext.TagAttributeInfo?

你有相互冲突的罐子。
发行版lib/jsp
中的文件适用于JSP的Glassfish实现。
现在不推荐使用Glassfish实现(由于实施者的错误数量和缺乏更新),并且在即将发布的Jetty 9.3版本中已完全删除。
不要将这些Glassfish实施jar包括在您的项目中。
仅使用发行版lib/apache-jsp/
目录中的4个jar,这是Apache Jasper JSP实现。
Apache Jasper JSP实现完全受支持,稳定,最新,并且拥有一个积极健康的社区和开发人员基础。
