Re: [jetty-users] various problems with embedded jetty (in web app)
|
Eugen,
If you're using jetty-8, then that uses jsp 2.2. In that version of
jasper, the tld files are found via a ServletContainerInitializer,
which is called when the context is about to be deployed and which
examines all the jars in the webapp and container classloaders for
tlds (note that it also insists that jstl tlds are found from jars in
the container classloader only). You will need to have the
AnnotationConfiguration class in jetty's list of configurations
applied to webapps in order to make this work - here's the usual list
applied to webapps:
<Call name="setAttribute">
<Arg>org.eclipse.jetty.webapp.configuration</Arg>
<Arg>
<Array type="java.lang.String">
<Item>org.eclipse.jetty.webapp.WebInfConfiguration</Item>
<Item>org.eclipse.jetty.webapp.WebXmlConfiguration</Item>
<Item>org.eclipse.jetty.webapp.MetaInfConfiguration</Item>
<Item>org.eclipse.jetty.webapp.FragmentConfiguration</Item>
<Item>org.eclipse.jetty.annotations.AnnotationConfiguration</Item>
<Item>org.eclipse.jetty.webapp.JettyWebXmlConfiguration</Item>
</Array>
</Arg>
</Call>
Hope that helps,
Jan
