Jetty中无法编译JSP类

Question

我正在将一个web应用从JBOSS迁移到Jetty。我能够启动应用，但当我尝试访问登录页面时，堆栈跟踪中出现以下错误：

org.eclipse.jetty.servlet.ServletHandler doHandle

信息：我正在使用Jetty 9.2.0.v20140526。 - Atul Kumbhar

Atul，你找到答案了吗？ - Eric

附上无法编译的JSP文件。 - Gas

请同时发布JSP代码，可能是由于JSP本身的问题导致无法编译。 - Ankur Singhal

这可以通过将 JSP 实现从 apache 修改为 glasfish 来解决。我在我的应用程序的 start.ini 中添加了以下条目：

#
# Initialize module jsp
#
--module=jsp
# JSP Configuration

# Select JSP implementation, choices are
#   glassfish : The reference implementation
#               default in jetty <= 9.1
#   apache    : The apache version
#               default jetty >= 9.2
jsp-impl=glassfish

# To use a non-jdk compiler for JSP compilation when using glassfish uncomment next line
-Dorg.apache.jasper.compiler.disablejsr199=true
