Re: [jetty-users] tag libraries in container

[Benjamin Jaton <benjamin.jaton@xxxxxxxxx>]

Hi Jan,

I'm using 9.3.8.v20160314.

Yes that's true, it comes with the default distribution and I could use this one.

However I also have the same question for, say, the tiles taglib for example, and a few others.

Thanks

Ben

Benjamin,

You don't say what version of jetty you are using, but jetty has provided the jstl jars for many releases now. All you have to do is enable the jstl module.

The technique you want ...

First: setup a proper ${jetty.base}

Second: don't ever modify/change/edit/delete/rename any content in ${jetty.home}

Third: keep the directories separate, not nested within each other.

If you want arbitrary libs to exist in the server classpath, enable the "ext" module for your ${jetty.base} and put them in your ${jetty.base}/lib/ext/ directory.

Test if you have the server classpath setup correctly by ...

$ cd /path/to/my/jettybase

$ java -jar /path/to/my/jettyhome/start.jar --list-config

Hello,

I have an existing embedded jetty and I would like to have the jstl-1.2.jar shared instead of having it inside each war.

So I am setting the jetty.home property to /path/to/folder/

and I put the jar in /path/to/folder/lib/web/jstl-1.2.jar

Then I set this:

webAppContext.setAttribute("org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern",
                ".*/jstl-1.2.jar$");

https://www.eclipse.org/jetty/documentation/9.2.7.v20150116/configuring-webapps.html

However I still get this error in my logs:

org.apache.jasper.JasperException: /WEB-INF/jsp/login.jsp (line: 1, column: 1) The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application

I tried to use ".*/.*/jstl-1.2.jar" and the full path of the jar without success.

I tried to switch to DEBUG but I couldn't see anything about scanning the jars (just the o.e.j.a.AnnotationParser ones)

Any idea?

Thanks,

Ben
