Hi, I tried to follow the instructions here: http://platform.xwiki.org/xwiki/bin/view/Main/ShortURLs and the URLs look great, but I couldn't get the skins and logo to work. The problem is this part of the instructions: <servlet> <servlet-name>defaultSkins</servlet-name> <servlet-class>org.mortbay.jetty.servlet.Default</servlet-class> <init-param> <param-name>relativeResourceBase</param-name> <param-value>skins</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>defaultSkins</servlet-name> <url-pattern>/skins/*</url-pattern> </servlet-mapping> This is totally wrong for me. I'm using xwiki + Jetty + lighttpd on Debian stable/testing. The correct entry into web.xml is to add: <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>/resources/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>/skins/*</url-pattern> </servlet-mapping> in addition to: <servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> It would also help if someone wrote WHERE to put these things in the web.xml file. I guessed, and it appears to work. thanks, Paul

Further to this, I discovered this fix does not work, as the /resources/* mapping seems to conflict with the *.gwtrpc mapping (mentioned in another email). When you Create A Link in the wysiwyg editor, it POSTs to: /resources/js/xwiki/wysiwyg/xwe/HTMLConverter.gwtrpc how do I set up my web.xml file so that both the static resources, and these apparently dynamic resource are able to both work? Please help, this is very frustrating. thanks Paul

In the default XE distribution the WYSIWYG editor is the only one making GWT-RPC calls and they all go to *.gwtrpc URLs so you're safe.

Ok, I have a solution that works for me.

HOWEVER, it will only work if ALL of the gwtrpc requests will be to urls such as domain.com/resources/blah/blah/file.gwtrpc

In the default XE distribution the WYSIWYG editor is the only one making GWT-RPC calls and they all go to *.gwtrpc URLs so you're safe.

This is the way I could have done it, if I had known where to put that

java

code etc:

http://www.kuligowski.pl/java/rest-style-urls-and-url-mapping-for-static-co…

The fundamental problem is due to the limited power of servlet mapping rules. ANY mapping to *.gwtrpc will not work if there is a /* mapping or a /resource/* mapping, as file extensions are always the lowest priority. So, instead of going the java-path, I used lighttpd since I am using it anyway. My new lighttpd rules are: $HTTP["host"] =~ "^www\.domain\.com$" { # ensure all requests for .gwtrpc files go through $HTTP["url"] =~ "\.gwtrpc$" { proxy.server = ( "" => (( "host" => "127.0.0.1", "port" => 8080

)))

} # otherwise, we can handle the static resources else $HTTP["url"] =~ "^/resources/" { alias.url += ( "/resources" => "/usr/share/jetty/webapps/root/resources" ) } # otherwise, we can handle the static resources else $HTTP["url"] =~ "^/skins/" { alias.url += ( "/skins" =>

"/usr/share/jetty/webapps/root/skins" )

} # and here is the primary server else $HTTP["host"] =~ "^www\.domain\.com$" { proxy.server = ( "" => (( "host" => "127.0.0.1", "port" => 8080

)))

} } else $HTTP["host"] =~ "\.domain\.com$" { url.redirect = ( "^/(.*)" => "http://www.domain.com/$1" ) server.name = "www.domain.com" } else $HTTP["host"] =~ "domain\.com$" { url.redirect = ( "^/(.*)" => "http://www.domain.com/$1" ) server.name = "www.domain.com" } so lighttpd will serve static content from resources and skins, EXCEPT if

ends with .gwtrpc THEN in web.xml: I change the gwtrpc mapping to: <servlet-mapping> <servlet-name>gwtrpc</servlet-name> <url-pattern>/resources/*</url-pattern> <url-pattern>/skins/*</url-pattern> </servlet-mapping> because we know that anything that makes it past lighttpd in the

resources

or skins folder MUST be a gwtrpc file. AND then I do not need the skins/resources mappings (that I mentioned

above

in prev email), all I need to add is: <servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> yay.

please put this up on the wiki for ShortUrls, it might save someone like

quite a few hours.

I've made the changes to http://platform.xwiki.org/xwiki/bin/view/Main/ShortURLs can someone please check it over for me? thanks Paul
