I am trying to use the httpserver library. When I load the files from another directory apart from DirAssets, it doesn't work. For example, when I use the code below:
B4X: 
Sub GetTemplate(Name As String) As String
    If templates.ContainsKey(Name) Then Return templates.Get(Name)
    Dim temp As String = File.ReadString(rp.GetSafeDirDefaultExternal("")&"/"&Main.linkname, Name)
    Log("temp"&temp)
    templates.Put(Name, temp)
    Return temp
End Sub
It gives an error that "Error serving request: (FileNotFoundException) java.io.FileNotFoundException: newlink\index.html"

Does it only work with DirAssets? How can I make it work with other directories?

Error has nothing to do with HttpServer.

As a general rule: no reason to use the external storage. Best to use File.DirInternal = XUI.DefaultFolder.

If you do want to use the external storage then the subfolder must be set like this:
B4X: 
Dim temp As String = File.ReadString(rp.GetSafeDirDefaultExternal(Main.linkname), Name)

i have tried using File.DirInternal and i also tried setting subfolder with
B4X: 
File.ReadString(rp.GetSafeDirDefaultExternal(Main.linkname), Name)
but in both cases, i get the same error. If I use File.DirAssets, it works perfectly. I have confirmed the files exist in above locations by listing contents of the directories. I have also noted that if the file still exists in File.DirAssets, then the server points to that file even if I set
B4X: 
Dim temp As String = File.ReadString(rp.GetSafeDirDefaultExternal(Main.linkname), Name)
. But if I remove the file from DirAssets, it now shows the error, though my application doesn't point to DirAssets

i am trying to load the attached html game since it doesn't work directly on webview unlesss it is served from a server. My Code is as below (the rest of the code is as in the example httpserver project):
B4X: 
Sub GetTemplate(Name As String) As String
    If templates.ContainsKey(Name) Then Return templates.Get(Name)
    Dim temp As String = File.ReadString(File.DirInternal&"/"&Main.linkname, Name)
    Log("temp"&temp)
    templates.Put(Name, temp)
    Return temp
End Sub

Sub HandleMainPage (Response As ServletResponse)
    Dim MainPage As String = GetTemplate("index.html") 'load the template from the assets folder
    Response.SetContentType("text/html")
    Response.SendString(MainPage)

End Sub
then on the webview it is as below:
B4X: 
StartService(ServerService)  
Sleep(4000)
Dim ssocket As ServerSocket
 WebView1.LoadUrl(ssocket.GetMyWifiIP & ":" & ServerService.port)

After running this, I get the below error:
Error serving request: (FileNotFoundException) java.io.FileNotFoundException: style.css
Error serving request: (FileNotFoundException) java.io.FileNotFoundException: scripts\main.js
Error serving request: (FileNotFoundException) java.io.FileNotFoundException: scripts\supportcheck.js

etc for each file in the project

Are you using xHttpServer?

[B4X] xHttpServer (Http Server + jQuery)

It is a personal project of mine that I started as a hobby on B4i and it has become an interesting project, so that I have modified it to be multiplatform. It is an http server, which allows a browser to navigate on html pages stored on the device. In addition, dynamic pages can also be...

The value of Main.linkname is game2 (name of the unarchive directory for the contents) and full logs are as shown below:
