Per instructions found in here embedded jetty unable to parse web.xml when jsp jars present in classpath I put together the following startup code to launch jetty with jsp support in embedded mode but still having no luck. I'm gettign the following error, full stack provided farther below:
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
The class in question, javax.servlet.jsp.tagext.TagAttributeInfo, is defined in org.mortbay.jasper.apache-jsp-8.0.9.M3.jar. This jar is also required for other reason, to bring in the class JasperInitializer, superclass of JettyJasperInitializer.
I'm suspecting that using the jar org.mortbay.jasper.apache-jsp-8.0.9.M3.jar is not recommended for jetty 9.2.10.v20150310. If so - what's the alternative? Wher should I get org.apache.jasper.servlet.JasperInitializer and javax.servlet.jsp.tagext.TagAttributeInfo?
