Android Question XML to Json, something is missing

[rkmoray]

I am trying to convert an xml file to json for processing. I am following the samples from another threat, and the sample works.
But when I move the code into my app, it fails.
The fail is on the initialize
Dim jo As JavaObject
jo.InitializeNewInstance("org.json.XML",Null) //this is where the fail occurs

My project has JavaObject 2.05, XMLBuilder 1.00, and Json 1.10.

Which example?

The fail is on the initialize

It fails with WHICH error? Hiding the error-message does not help us to help you

Please use quote tag when posting errorlog!

And you did not answered from which example you are talking about.

 

[rkmoray]

The sample was from the "B4AJsontoXml" download. It is located at
"https://www.b4x.com/android/forum/threads/json-to-xml-and-xml-to-json.41830/"

 

[DonManfred]

Did you referenced the needed java-json.jar? (is it inside your additional library folder?

Maybe add a

#additionaljar: java-json

 

[rkmoray]

Thank you for the suggestion.
I already had the reference call in my application, as well,
as the java-json.jar is in the library folder.
Interesting how it does not have an xml file.
But that still does not help me understand why is works in the sample, but not in my code.

 

[DonManfred]

I already had the reference call in my application, as well,

do you want to bet on this? I put a "cinemavisit (15$)" in the pot

NO. You did not implement it correctly.
Check your code and check the example.
ONE line is missing. The #additionaljar-line!

 

[rkmoray]

Here is the sample "
#Region Project Attributes
#ApplicationLabel: JsXl
#VersionCode: 1
#VersionName:
'SupportedOrientations possible values: unspecified, landscape or portrait.
#SupportedOrientations: unspecified
#CanInstallToExternalStorage: False
#AdditionalJar: Java-Json
#End Region"
and here is my attribute section
"
#Region Project Attributes
#ApplicationLabel: evMobile
#VersionCode: 1
#VersionName:
'SupportedOrientations possible values: unspecified, landscape or portrait.
#SupportedOrientations: unspecified
#CanInstallToExternalStorage: False
#AdditionalJar: Java-Json
#End Region

#Region Activity Attributes
#FullScreen: False
#IncludeTitle: True
#End Region"

 

[DonManfred]

Here is the sample

i know the sample-code. I had a look at it.
Again:
You are missing a essential line. I also suggested this (in post #6) to add this line but you told you DID add it (which is not true!).

Tip: search for "additionaljar" in the sample-code

 

[rkmoray]

I do not understand, in line #8 of my code (as in the previous post) is "#AdditionalJar: Java-Json"

 

[Misterbates]

There's no path before the jar filename ... Where have you saved your code and where have you saved the example code in relation to the jar file? Is there another copy of the jar file in the example folder that it can find but that your version can't find?

 

[rkmoray]

It was only in my additional library folder, but I just added as well to my internal library folder. No difference.
I get the same error.

 

[eps]

Is the filename correctly named? Android is case sensitive...

 

[rkmoray]

That was it. Case sensitivity.
Thank you to all who helped. Very much appreciated.
