B4J Question *.jar file not recognized in External Library path

[TorontoJim]

I have a jar file from Bouncy Castle that I have placed in the configured folder for external libraries. The file is not being recognized according to testing. Do I need to do something else to use the file, e.g. an import statement or similar?

A single jar file without a correcponding xml file is just a JAR. Nothing more.There is NO library here.

If you need to use it you need to add it to your project with #additionaljar

I've added that and it is still failing. Is my syntax/placement correct for the above?

#AdditionalJar: bcprov-jdk18on-1.83

'Non-UI application (console / server application)
#Region Project Attributes
    #CommandLineArgs:
    #MergeLibraries: True
#End Region

Sub Process_Globals
    
End Sub

Sub AppStart (Args() As String)
    Try
        Dim jo As JavaObject
        jo.InitializeNewInstance("org.bouncycastle.crypto.engines.ChaCha20Poly1305", Null)
        Log("SUCCESS: BC is loaded")
    Catch
        Log("FAIL: BC not loaded")
    End Try
End Sub

 

[DonManfred]

Remove the try catch and post the error you get

 

[DonManfred]

org.bouncycastle.crypto.engines.ChaCha20Poly1305

is probably org.bouncycastle.crypto.modes.ChaCha20Poly1305

 

[TorontoJim]

is probably org.bouncycastle.crypto.modes.ChaCha20Poly1305

You were correct, that fixed it. Thank you.
