Hi,

Does the file

/var/lib/tomcat7/webapps/demo/bbb1.jsp

exist and readable by tomcat7 (i.e. does it have the same permissions as

/var/lib/tomcat7/webapps/demo/demo2.jsp

Regards,... Fred

Hi Lista,

I did a quick google for

Linux file permissions

and found the following that should help

https://www.linux.com/learn/understanding-linux-file-permissions

Give the above a read and let us know if you are still need help comparing the permissions of two files.

Regards,.. Fred

thank you very much Fred, but by that I see the two files have the same permissios

-rw-rw-r-- 1 bbb bbb 575 Dec 13 20:42 bbb1.jsp
-rw-rw-r-- 1 bbb bbb 604 Dec 13 19:17 demo3.jsp
-rwxr-xr-x 1 root root 632 Nov 4 11:47 install-ffmpeg.sh

What can be the problem that sent the error? ΄:(

Hi Litsa,

That looks fine. What happens when you try accessing demo2.jsp. You can compare with our demo server

http://demo.bigbluebutton.org/demo/demo2.jsp

Hi Lista,

It's hard to say why your page does not appear. Try backing up your page, and then copying demo2.jsp to bbb1.jsp and see if you can load

/demo/bbb1.jsp

Those look like permissions for your personal directory "/home/<username>", but Fred was specifically asking about "/var/lib/tomcat7/webapps/demo" where tomcat serves up the jsp files from.

Running "ls -l /var/lib/tomcat7/webapps/demo/" should give very different results from the one you posted.

ummm are you using a custom index.html file you can edit the front page with a dropdown to join the room you want and also change the demo it goes to from with in . here is a custom index you can edit and add your jsp name in it with your room names and then just drop the index.html in your bluebutton you will need to add your own logo and changes the welcome message

index.html

When I try to ping that domain name it can't resolve. Make sure the domain name is setup correctly with your provider. If you've just recently setup the subdomain it can take a bit for the change to filter through the various DNS servers.

I was talking about pinging the domain in your previous post, "bbb.mscinformatics.gr". When I try to ping the domain it can't resolve whereas if you ping something like "google.com" your computer will resolve the name to an IP.

did you just pick that name or is that your real domain site its being hosted ... you could try your host file add your ip and point it to your domain name that your using . I just want to know where you getting that domain name from
