| configuration of servlet-mapping in web.xml [message #65870] |

The standard configuration for the servlet mapping to the equinox bridet
servlet looks like this:
<servlet-mapping>
<servlet-name>equinoxbridgeservlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
If the url pattern is limited to a certain path, always a 404 error is
returned when trying to access the RAP application.
This can be reproduced with the rapdemo.war file from CVS. The
configuration looks like this:
<servlet-mapping>
<servlet-name>equinoxbridgeservlet</servlet-name>
<url-pattern>/rap</url-pattern>
</servlet-mapping>
The leads to the following error page:
HTTP Status 404 - ProxyServlet: /rapdemo/rap
type Status report
message ProxyServlet: /rapdemo/rap
description The requested resource (ProxyServlet: /rapdemo/rap) is not
available.
Apache Tomcat/5.5
The errors seems to come from the equinox http service. Any suggestions?
Regards,
Stefan.

Hi Stefan,
you are right, it's easy to reproduce - and just doesn't work.
Could you file a bug report to track the progress on that issue?
Cheers,
Rüdiger

Hi,
For my application, running under Tomcat, I wanted to be able to only
send some URL requests to Equinox and have others be handled normally.
I ran into the same problem you describe, and the way I found to get
around it was to use a pattern which was not simply '/*' but which did
contain a *:
<servlet-mapping>
<servlet-name>equinoxbridgeservlet</servlet-name>
<url-pattern>/app/*</url-pattern>
</servlet-mapping>
You can then send some URL's to Equinox:
http://localhost:8080/rapdemo/app/rap
And others not:
http://localhost:8080/rapdemo/index.html
I imagine that the recommended way to serve static HTML files in a RAP
application would be to put them in the application's exported plugin
JAR and address them through the extension point redirection in the
application's plugin.xml. For example:
<extension
point="org.eclipse.equinox.http.registry.resources">
<resource alias="/help" base-name="/help_files"/>
</extension>
Then for the following request:
http://localhost:8080/rapdemo/help/index.html
It will find the file under the classpath (e.g. in the plugin's
exported JAR):
/help_files/index.html
I used this for static HTML files (help files in my app). However, for
dynamically generated HTML files, I used the method described above,
ensuring that the URL's do not get sent through to Equinox:
http://localhost:8080/rapdemo/index.html
Thanks,
Ryan
