Re: [jetty-users] tag libraries in container
Benjamin,

You've distracted me with the AnnotationConfiguration :)  That's not what you want to be looking at for finding the tlds. That is controlled by the MetaInfConfiguration based on jar names that are matched in WebInfConfiguration from the containerIncludeJarPattern.  Do a server.setDumpAfterStart(true) and you should see what your classloader hierarchy and jetty setup looks like.

I do have the jar in the classpath: java -cp (...) my.custom.WebServer

It finds my own classes and more properly so I'm pretty sure that the jar itself is in the classpath (I see it when I run the 'ps' command, and the path resolves correctly).

I use this now to rule out any syntax issue:
webAppContext.setAttribute("org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern",   ".*\\.jar$");
webAppContext.setAttribute("org.eclipse.jetty.server.webapp.WebInfIncludeJarPattern", ".*\\.jar$");

And I still see that message:

2016-05-10 16:46:01 DEBUG o.e.j.a.AnnotationConfiguration:570 - Scanned 0 container path jars, 4 WEB-INF/lib jars, 1 WEB-INF/classes dirs in 279ms for context o.e.j.w.WebAppContext@2e3b4394{/main,file:///path/to/work/main/webapp/,STARTING}{/path/to/web/main.war}

Thanks,
Ben

Benjamin,

You need to put whatever jars you want to use that are external to the webapp explicitly onto the classpath for your embedded runtime - we look at the classloader parent of the webapp to find container jars for name matching and thus annotation scanning etc.

 Also probably best to double escape the "." in ".jar" in a java string so its "\\.jar"

Did I mention that I was using an embedded Jetty? I am not using start.jar, and I don't have a real "jetty.home" for Jetty.

I did set manually jetty.base though:
        System.setProperty("jetty.home", "/path/to/folder/");
        System.setProperty("jetty.base", "/path/to/folder/");

Those libs are also used by other applications, so I'd rather not have them in a folder that is specific to jetty.
Can I specify container libs without / outside a jetty base?

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
