I am wondering if it is possible to place zul files outside the web application folder or war file.

I would like to have my ViewModels and supporting classes as normally in WEB-INF/classes but certain zul files in a separate external location so I could, for instance, add some zul files on the fly.

In JSF this can be achieved by using javax.faces.view.facelets.ResourceResolver or javax.faces.application.ResourceHandler...

Any insight is highly appreciated. I was navigating the docs, especially ZK config reference manual 8.5.1 but didn't seem to find a fit. I'm wondering about org.zkoss.zk.ui.util.URIInterceptor

Ideally I would like to solve the problem declarively.


This is for production use. I have an application where plugins can be added at runtime. This works pretty well. In plugins, developers can bundle zul files...

I use jetty so app's .war ends up extracted to a random temp directory. By using servletContext.getRealPath("/") I know this physical path, so I simply extract the files there. That way, zul files are served with no effort

The problem arises in a clustered environment (same app running at different nodes), because the temp path is not the same across all nodes, so I need to use a predefined location to place zul files.

Thanks for reading!

is this for development or production use? An answer or recommendation would likely vary based on the intended purpose.

Thanks for contributing @hawk , it is close to what I need, however jars are added at runtime (using a plugin framework - pf4j) so unfortunately, these are not present in the classpath.

After some more digging I found this (I cannot paste links):

wiki > Developer's Reference > Customization > UI Factory

So I will follow a strategy similar to that of loading zul from database, but reading instead from a static external filesystem location

I hope that should do it

thanks for the update (I guess I missed that feature since it's rarely used/asked for) ... I added some Karma so you can post links next time

I think Classpath Web Resource Path can fulfill your requirement.
