Spacer gif URL wrong after upgrade to JBoss 8 (RF 3.3.3)
I'm doing an upgrade from JBoss 6 to JBoss 8 (WildFly). The version of RichFaces 3.3.3 has stayed the same. Several places in the code call the RichText spacer, like this:
<rich:spacer height="15" width="5"/>
In `web.xml`, the `servlet-mapping` entries related to Faces looked like this:
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
When running JBoss 6, the spacer image had the following URL, which worked fine:
https://host.com/dc/a4j/g/3_3_3.Finalimages/spacer.gif
We start running into issues when we upgrade to JBoss 8. The URL suddenly looks like this, and returns a 404 Not Found when accessed:
https://host.com/dc/faces/a4j/g/3_3_3.Finalimages/spacer.gif
I tried removing all but the `*.jsf` `servlet-mapping` from `web.xml`, [like the documentation specifies](https://docs.jboss.org/richfaces/latest_3_3_X/en/devguide/html/GettingStarted.html). This made the URL look like this:
https://host.com/dc/a4j/g/3_3_3.Finalimages/spacer.gif.jsf
The URL returns a 500 Internal Server Error when accessed:
ERROR [io.undertow.request] (default task-29) UT005023: Exception handling request to /dc/a4j/g/3_3_3.Finalimages/spacer.gif.jsf: javax.servlet.ServletException: org.ajax4jsf.resource.ResourceNotFoundException: Resource not registered : images/spacer.gif.jsf
The image is always available the original URL.
I just assume bypass the issue and do away with the spacer, but the spacer is also called internally, within some of the RichFaces components that we are currently using.
What should I do to get the spacer to show up correctly?
