java.lang.NoSuchMethodError:带有嵌入式码头并带有jsp支持的javax.servlet.jsp.tagext.TagAttributeInfo

jsp

根据在这里找到的指令,当类路径中存在jspjar时,嵌入式jetty无法解析web.xml,
我将以下启动代码放在一起,以嵌入式模式启动具有jsp支持的jetty,但仍然没有运气。我收到以下错误,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。出于其他原因,也需要此jar来引入JasperInitializer类(JettyJasperInitializer的超类)。

我怀疑码头9.2.10.v20150310不建议使用jarorg.mortbay.jasper.apache-jsp-8.0.9.M3.jar。如果是这样,还有什么选择?我应该获得org.apache.jasper.servlet.JasperInitializer和javax.servlet.jsp.tagext.TagAttributeInfo吗?

您有冲突的jar。

发行版中的文件lib/jsp用于JSP的Glassfish实现。

Glassfish实施现在已被弃用(由于大量的错误且缺乏实施者的更新),在即将发布的Jetty 9.3版本中已将其完全删除。

不要在您的项目中包含这些Glassfish Implementation jar。

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实施受到完全支持,稳定,最新,并拥有活跃而健康的社区和开发人员基础。
