Tomcat rewrite valve and Servoy WebClient

Classic Servoy
1

Hi,

I am trying to use the Tomcat rewrite valve to map a specific domain name to the web client startup screen in a specific context (e.g http://app.mydomain.com gets rewritten to http://app.mydomain.com/myContext/servo … /s/AppName). I have enabled the rewrite valve for my ROOT context and placed the following in the rewrite.config file:

RewriteCond %{HTTP_HOST} ^app.mydomain.com$
RewriteRule ^/index.jsp$ /myContext/servoy-webclient/ss/s/AppName [L]
RewriteRule ^$ /myContext/servoy-webclient/ss/s/AppName [L]
RewriteRule !^/myContext/.*$ [C]
RewriteRule ^/(.*)$ /myContext/$1 [L]

If I then enter the URL http://app.mydomain.com/servoy-admin then I am taken to the admin screen within the myContext context and everything works as expected. I can use all the admin functions with no issue and the URL displayed in the browser does not show the context part. If however I try and go to the actual application by entering http://app.mydomain.com I can see the initial “Loading…” message come up but then my screen remains blank and I get the following error in the Servoy log:

There is no ClientId or Solution Name given in the log which seems odd.

Can anyone give me any pointers as to what i am doing wrong? Alternatively if you have a working example using the UrlRewriteFilter from Tuckey.org then I would be grateful as I should be able to adapt that for the Tomcat rewriteValve.

Many thanks
Steve

i am not sure if that will really work, because rewriting the above then wicket relative urls are not all working correctly

Because the page is also hitting stuff below that /myContext/servoy-webclient/ss/s/AppName (so it also wants to ave urls like myContext/servoy-webclient/resources/xxx and so on)

So to rewrite that we really need to look deep into it, but i think the “myContext” can be rewritten and maybe also myContext/servoy-webclient but more i don’t think so)
