            Bug ID: 56045
           Summary: Cannot start embedded container without Jasper
           Product: Tomcat 7
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Jasper
          Assignee: dev@tomcat.apache.org
          Reporter: david_syer@hotmail.com

If I don't have a web.xml and I'm not using JSPs I shoudln't need Jasper on the
classpath (it worked in 7.0.47)

Good to know that jasper is a sufficient but not necessary dependency, but that
doesn't really help if you don't want anything to do with JSPs.

I did raise this issue specifically against Tomcat 7. It's a regression (and a
pretty significant one) between 7.0.47 and 7.0.50, so I'm kind of hoping it
might be fixable.

You do not need Jasper, but you need the JSP APIs - the "jsp-api.jar" file.

1. The common XML Schema for the Servlet 3.0 deployment descriptor does depend
on the XML Schema for the JSP 2.2 deployment descriptor.

2. Tomcat processes tag libraries and instantiates Listeners defined in their
TLD files regardless of whether you use Jasper. This may need the schema for
TLD files.


Note that both of these issues have been fixed in Tomcat 8.
Re: 1: in Tomcat 8 the schemas are bundled in servlet-api.jar
Re: 2: in Tomcat 8 the listeners are initialized by Jasper and are injected
into web application via ServletContext.addListener() API.
