Remove the wfgen sub folder/application

Administration Installation
1

Hi,

I have been using WorkflowGen for over 10 years now and everytime I do a new install I hate seeing that sub application /wfgen/ in IIS. I hate having the users remember that Url. Is there a way to remove that application and simply install WorkflowGen on the root Website?

So instead of always having to go to http://localhost/wfgen, you can simply go to http://localhost.

The URL rewrite option is not a solution, I don’t want to redirect the user, I want to get rid of the /wfgen/ sub folder completely.

Thanks,

Hi,

In IIS, you can simply change the physical path of the root website to “…\wwwroot\wfgen” instead of “…\wwwroot”. Localhost will then point to the \wfgen folder.
(Right click on website -> Manage Website -> Advanced Settings…)

Make sure to also modify the Application URL configuration so that it matches with your setup changes.

Best Regards,
Eddy.

I will try that approach again. In the past, this caused problems since some parts of the system always point to /wfgen/.

I will try and let you know if it works.

Thanks,

The solution you recommend does not work because of the WorkflowGen Engine Service. Look at this discussion for explanation.

Hi,

This is a very old article (9 years old) and I’m discussing with the team to remove it.
I tried my solution and it worked fine without the “/wfgen” path. The services were running fine as well.
Have you tried it on your side?

Best Regards,
Eddy.

I will try it again and let you know.

It doesn’t work for me. New installation from PowerShell. I get the following error when trying to run the service. If I change it back with the wfgen subfolder, it works.

Service cannot be started. System.NullReferenceException: Object reference not set to an instance of an object.

Wait a minute! I found the problem.

When there is no end slash “/” at the end of the Url in the Web.config, it doesn’t work. Making sure that ending slash is there works!

This does not work:
<add key="ApplicationUrl" value="http://localhost" />

This works!
<add key="ApplicationUrl" value="http://localhost/" />

So make sure the end slash at http://localhost/ is there!

Here is another issue I found with the graphql.

You need to modify the server.js file to change the rootUrl

const rootUrl = ‘/graphql’;

Instead of…

const rootUrl = ‘/*/graphql’;

Hi,
Thank you for mentioning this. We will correct this in the upcoming version.
