Re: [jetty-users] various problems with embedded jetty (in web app)

[Eugen Cepoi <cepoi.eugen@xxxxxxxxx>]

I'm running jetty from inside my "executable war". 
I've extracted the server dependencies (all content of jetty jars,jsp,servlet,etc) at the root of the war and removed them from WEB-INF/lib.
So in this way they are in the containers classpath no? For jstl I'm using javax.servlet:jstl artifact.

I'm doing surely something wrong as it works when I run it from eclipse, but I can't find what...

Here are the relevant parts of the pom I use. Thank's!

Eugen,

The jstl jars need to be on the container's classpath, not inside your
webapp. Can you see the $JETTY_HOME/lib/jsp directory contains the
jstl jars org.apache.taglibs.standard.glassfish_1.2.0.v201004190952.jar
and javax.servlet.jsp.jstl_1.2.0.v201004190952.jar

regards
Jan
