Steps to reproduce: Into a virgin Jetty install (I just said apt-get install jetty), add a webapp like so
<Call name="addWebApplication"> <Arg>some.vhost.name</Arg> <Arg>/</Arg> <Arg>/path/to/webapp</Arg> </Call> place this in /path/to/webapp/index.jsp: JSP says: <%= "Hello world" %> presto, NoClassDefFoundError: 08:16:20.774 WARN!! [SocketListener0-9] org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:589) >11> /: java.lang.NoClassDefFoundError: org/apache/commons/el/ExpressionEvaluatorImpl at org.apache.jasper.compiler.JspUtil.<clinit>(JspUtil.java:62) at org.apache.jasper.JspCompilationContext.getServletClassName(JspCompilationContext.java:293) at org.apache.jasper.JspCompilationContext.getClassFileName(JspCompilationContext.java:433) which promptly disappears after adding the class to /etc/jetty/start.config as described by Daniel above. Please do tell if I can provide any more information to debug this problem. Wolfgang -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
