Question

您好我在Eclipse中使用嵌入式Jetty 8.x并获得此错误，同时使用JSP和Servlet创建简单的 Hello Web应用程序。我在Build Path中错过了一些jar吗？

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: -1 in the jsp file: null

我将继续并在答案中提供更多细节，因为我也面临同样的问题（或足够接近），当运行形式eclipse并投掷

时应用程序工作正常

java.lang.NoSuchMethodError: org.apache.jasper.compiler.JspUtil.expandClassPath(Ljava/util/List;)Ljava/util/List;

导出并运行时形成一个可运行的jar。

soloution（如上面的评论中所述）是在导出之前将jasper-compiler-*.jar和jasper-runtime-*.jar添加到eclipse中的类路径（其中asterix是版本号）。我分别在jasper-compiler.jar和jasper-runtime.jar

找到了这些内容

如果这些链接在阅读时已失效，则Google搜索（或使用jar finder等服务）可帮助您找到上述所需的广告。

面对java.lang.NoSuchMethodError：Jetty + Eclipse
