B4J Question [Solved] Calling External Jar - How?

[Harris]

' Project Attributes - added...
#AdditionalJar: rtf-To-html-1.0.0

I need to call this jar to return a formatted HTML by passing it a RTF string to convert.
I think it is a simple jar - pass it a RTF string and it will return a HTML string....
(I want to show the result in a ABMEditor - Squire sourced...).

I expect I will need to use JavaObject, but don't know what to do next....

This is the source of the jar:

GitHub - bbottema/rtf-to-html: RTF to HTML conversion done right

RTF to HTML conversion done right. Contribute to bbottema/rtf-to-html development by creating an account on GitHub.

github.com

I got the jar from:

Download rtf-to-html JAR 1.0.0 ➔ With all dependencies!

RTF to HTML conversion done right ✓ Download JAR rtf-to-html 1.0.0 ✓ With dependencies ✓ Source of rtf-to-html ☄ One click! ☄

jar-download.com

Is this the way or some other method?

Thanks

#AdditionalJar: rtf-to-html-1.0.0.jar
Sub Process_Globals
    
End Sub

Sub AppStart (Args() As String)
    Log(ConvertRTF("ewfjklw efj wklef "))
End Sub

Sub ConvertRTF (rtf As String) As String
    Dim jo As JavaObject
    jo = jo.InitializeStatic("org.bbottema.rtftohtml.impl.RTF2HTMLConverterClassic").GetField("INSTANCE")
    Return jo.RunMethod("rtf2html", Array(rtf))
End Sub

Works great!

Proving once again that everything is possible using B4X with guidance from the experts...

Sub ConvertRTF (rtf As String) As String
    
    Dim htmltext As String = "None"
    Log(" running rtf - html convert")
    
    Try
        Dim jo As JavaObject
        jo = jo.InitializeStatic("org.bbottema.rtftohtml.impl.RTF2HTMLConverterClassic").GetField("INSTANCE")

        '   these also work - with various results...
        '    jo = jo.InitializeStatic("org.bbottema.rtftohtml.impl.RTF2HTMLConverterJEditorPane").GetField("INSTANCE")
        '    jo = jo.InitializeStatic("org.bbottema.rtftohtml.impl.RTF2HTMLConverterRFCCompliant").GetField("INSTANCE")

        htmltext =  jo.RunMethod("rtf2html", Array(rtf))
    Catch
       Log(" error rtf convert: "&LastException.Message)   
    End Try
    Return htmltext
        
End Sub
