Accessing a JSP from different machine

[Mathews P Srampikal]

Hi all,

I created an application and accesing it using

http://localhost:8080/Test/init.jsp

OR

http://192.134.12.51:8080/Test/init.jsp

But,
When i access the same application from a different machine, using IP address,the page is not displayed.

What can be the problem?

Thanks,
Mats

Have you set up port 8080 in the firewall on the machine where the JSPs are running from??

Or maybe you need to port forward port 8080 in your router to the machine where the JSPs are running from...

can machine B ping machine A? (are they on the same network, do they have the right mask etc)

hi,

Have you set up port 8080 in the firewall on the machine where the JSPs are running from?? ==> default port is 8080, so where do we need other configurations.

I can ping from the other machine.

Thanks,
Mats.

What are the OS of the machine (Windows, Mac, Linux, etc)??

What kind of firewall are you using (Norton, ZoneAlarm, etc)

Can machine B call telnet on port 8080 on machine A? (telnet 8080)??

Rene,

I am using Widows OS and no firewall.

I am not able to connect using telnet <machine name>. What can be the problem.

Thanks,
Mats.

Windows OS (XP+) do have a build in firewall - unless you have disabled it.

Rene,

I have not disabled the firewall. i am not able to do telnet

telnet 192.156.2.22

it is giving following error :

Connecting To mats...Could not open connection to the host, on port 23: Connect failed.

Please tell me is there any tomcat configuration settings to be changed, or any other machine specific confiration problem?

Thanks,
Mats.

With telnet you can check if a specific port is responding - in this case you should check port 8080.

This is done be typing

telnet 192.156.2.22 8080

then you should get a 'new' prompt, which you can exit with 'CTRL + C' (it can take some time before it will exit - but it will).

If you don't get a new prompt, then I will suggest that you add port 8080 to your windows firewall.
