I'm installing DXA 1.4 Java version with SDL Web 8. I import publication to Content Manager, and added a new publication which is child of "400 Example Site".

The new publication's URL is "/jp"

Then I deployed DXA War file and modified its context root name to "jp".

When requesting DXA by URL like "http://server/jp/index.html", following error occurs.

org.apache.jasper.JasperException: javax.el.ELException: com.sdl.webapp.common.controller.exception.NotFoundException: Localization for /assets/css/main.css not found.

It seems DXA cannot resolve URL to publication.

How DXA resolve URL to publication?

How can I configure DXA to make this work?

UPDATE

I moved DXA directory "dxa-example-webapp" to docBase of Tomcat. The Tomcat's server.xml is following.

<Host name="localhost"  appBase="webapps" unpackWARs="true" autoDeploy="true">
        <Context path="/" docBase="/var/www/dxa-example-webapp" reloadable="true" />
</Host>

I removed DXA and newly installed again, so publication and Topology Manager settings are default values(publication URL is "/").

I accessed URL "http://54.238.137.132:55280/index.html".

DXA seems to find index.html and header.html, but NullPointerException occurs after that.

What kind of configuration is wrong?

DXA.log is following.

Found index.html.

Regards,

  • why deploy a new war, you can serve both from the same war which reduces the amount of total memory used and only one app to maintain? – Bart Koopman Jul 1 '16 at 12:52

There are Known Issues with running the DXA Web Application as a non-root Web Application.

But, as Bart mentioned, it seems you can just as well run the DXA Web App as root Web App and let it handle jp and possibly other URLs for other Publications; DXA can handle multiple Publications with one Web App.

The trick is to use appropriate mappings in Topology Manager: the mapping you use for your /jp site should have RelativeUrl="/jp".

  • I removed DXA and installed it again, beacuse my environment was too messy. Also, I moved DXA directory "dxa-example-webapp" to docBase of Tomcat.According to debug log, DXA seems to find a page by URL, but NullPointerException occurs. I edited my question. – Hirokazu Shikata Jul 5 '16 at 12:35
  • This is an entirely different problem. It would be better to mark the original Question as solved and create a new Question. – Rick Pannekoek Jul 5 '16 at 17:07

Regarding the second (updated) Question/problem: this is a symptom of a problem with the Context Service. There is a Known Issue with the CIL that errors occurring in the Context Service are not handled properly and result in a NullPointerException (I believe a CIL hotfix is available for the bad error handling).

Did you install the Context Service and register it as a Capability in the Discovery Service? Did you also create the device repository? Do you see errors in the Context Service logs?
