Hi Chris,
> <Context path="" docBase="towl" />
If i remove this from server.xml file i have the below error.
Message java.lang.NoClassDefFoundError: org/towl/indexer/web/Prefix
Description The server encountered an unexpected condition that prevented
it from fulfilling the request.
Exception
jakarta.servlet.ServletException: java.lang.NoClassDefFoundError:
org/towl/indexer/web/Prefix
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:333)
jakarta.servlet.http.HttpServlet.service(HttpServlet.java:658)
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:51)
The "aliasing" will always be weird. IMO it's better to redirect. If you
change to redirect, does everything *work*, even if you don't like how
the browser's URL bar displays?
--> I tried but it didnot work
ok apart from this tpic , we have one more issue found.
Actually application team, they are deploying two applications one with
towl (which you are already aware) the other one is (towl-app) they have
defined seperate server.xml for both.
Name: server.lbg.com
Address: 192.168.200.120
Aliases: example.lbg.com
Name: server.lbg.com
Address: 192.168.200.120
Aliases: example-app.lbg.com
which means we have two aliases for server.lbg.com , earlier we were
concentrating only on one example.lbg.com , now i wanted to somehow enable
access as the same for the other one also
https://example-app.lbg.com --> https://server.lbg.com:8444/towl-app
So i created iptable rule in the sameway as before redirect 443 to 8444 and
i have the urls working same as example.lbg.com
Both the server.xml files are here
/git/towl/apachetomcat/conf/server.xml
/git/towl-app/apachetomcat/conf/server.xml --> I changed the port of
connectors and everything
But now when i try to access https://example.lbg.com --> I get webpage of
https://example-app.lbg.com and sometimes i get webpage of
https://example.lbg.com after refresh itself which is wierd
May i know why this is happening. If we fix this then I am thinking to
disable the unwated urls leaving the required ones. for example the below
ones. I think that would be easier ? rather than redirecting or aliasing-->
Because we noticed that towl application is already pointing with
https://example.lbg.com
https://server.lbg.com:8443
https://example-lbg.com:8443
<https://example.lbg.com/towl>
<https://server.lbg.com/towl>
https://server.lbg.com:8444
https://example-lbg.com:8444
<https://example.lbg.com/towl-app>
<https://server.lbg.com/towl-app>
kindly suggest us a fix.
Thanks once again for your time
Regards,
Lavanya
