@orea 邢 , Apologies for the delayed response on this.

As I understand you are referring to the steps outlined in this doc’ for your Tomcat App on Windows App Service WebApp.
Mount Azure Storage as a local share in App Service

Just to clarify, is it on a VNET or /private endpoints?

Since virtual directories in Azure Web App for Windows are restricted to paths within the c:\home\site (or d:\home\site) physical path, there are additional steps to be able to reference BYOS files via the virtual directory path:

As outlined in the sample by one of colleague:

As an example: For ASP.NET Core / ASP.NET 6 or later and referencing BYOS static files that would normally be in the wwwroot folder of the application, you must override the default folder for static files.

Eg: If you have /mounts/SubFolder as the BYOS mount path, and the wwwroot static files folder directly under the Storage file share, you may use the following in the Program.cs or Startup.cs to serve the static contents from the BYOS-mounted wwwroot folder instead of the local wwwroot folder:

Reference: https://github.com/gabesmsft/AspNetStaticFilesDemo/blob/master/AspNetStaticFilesDemo/Program.cs#L17

• app.UseStaticFiles(new StaticFileOptions() • { • FileProvider = new PhysicalFileProvider(Path.Combine(Directory.GetCurrentDirectory(), "/../../../mounts/SubFolder/wwwroot")), • RequestPath = new PathString("") • });

Adding more:

Also, you may verify that the mount path is reachable within the Web App.

From the Kudu console https://<yourWebAppName>.scm.azurewebsites.net/DebugConsole , run cd c:\mounts .

Cd into the mount path subdirectory. For example, if the mount path is /mounts/test1 , run cd test1 .

For another example, if the mount path is /mounts/test1/folder1, run cd test1/folder1 .

If the mount path subfolder(s) are present but there are no contents or unexpected contents listed, you may check the File share in the Storage account to verify if the expected contents are present.

Kindly let us know, I'll follow-up with you further.

I use az command in the sample

It responds error message

The last response is gone. so I post a new one.

"Tomcat App on Windows App Service WebApp" ->Yes.

"is it on a VNET or /private endpoints" ->No. Is it necessary?

I use the az command in this article.

But it returns the error message in --debug parameter :

{"Code":"BadRequest","Message":"The parameter 'AzureStoragePropertyDictionary' has an invalid value. Details: Invalid MountPath for Windows Web App. Id: force, MountPath: /home/site/wwwroot/webapp/force. MountPath must be sub-directory of \mounts.","Target":null,"Details":[{"Message":"The parameter 'AzureStoragePropertyDictionary' has an invalid value.
