Tomcat – Is it possible to run IIS and Tomcat side by side

iistomcat

I am required to publish a JSP/Java servlets webapp. Unfortunately IIS does not support such deployments. The server I need to deploy it on already runs IIS and several IIS applications. I don't want to interfere with those applications but it is necessary for them and the new webapp to run on the same server. I tried setting up a proxy to redirect traffic to tomcat, but that broke the other applications.

I was wondering if it's possible to run IIS (accessible through good ol' port 80) and tomcat (running on port 8080); and be able to access both remotely. So far my efforts have been fruitless. Accessing IIS applications yielded no problems, but when I tried to connect to tomcat the browser would just time out. I unblocked port 8080 as well, so I'm sure that is not the issue.

Any help appreciated, thanks.

It's definitely possible, as long as they run on different ports. If you can access tomcat locally (http://localhost:8080) but not remotely, then it's a firewall issue. Also, if you really wanted you could have iis forward requests to tomcat.

You've another instance of Tomcat already running. You can confirm this by going to http://localhost:8080 in your webbrowser and check if you get the Tomcat default home page or a Tomcat-specific 404 error page. Both are equally valid evidence that Tomcat runs fine; if it didn't, then you would have gotten a browser specific HTTP connection timeout error message.

You need to shutdown it. Go to /bin subfolder of the Tomcat installation folder and execute the shutdown.bat (Windows) or shutdown.sh (Unix) script. If in vain, close Eclipse and then open the task manager and kill all java and/or javaw processes.

Or if you actually installed it as a Windows service for some reason (this is namely intented for production and is unhelpful when you're just developing), open the services manager (Start > Run > services.msc) and stop the Tomcat service. If necessary, uninstall the Windows service altogether. For development, just the ZIP file is sufficient.

Or if your actual intent is to run two instances of Tomcat simultaneously, then you have to configure the second instance to listen on different ports. Consult the Tomcat documentation for more detail.

C# – Error – Unable to access the IIS metabase

On Windows 8 Pro:

%systemroot%\inetsrv\config

On Windows 7 and 8.1 and 10

%systemroot%\System32\inetsrv\config

(Where %systemroot% is usually C:\Windows)

Navigate to the appropriate location above in Windows Explorer. You will be blocked access with a popup which says:

"You don't have access to this folder - Click continue to permanently get access to this folder"

Click 'continue' for this folder, and with the Export folder underneath. I changed the shortcut back to "Run as me" (a member of the domain and local administrators ) and was able to open and deploy the solution.
