Hello @Bua,

Welcome to forum!

The code should be separate from the discussion in the post so it is easy to read and a simple click of the mouse to copy the code.

It is also important to provide details:

- Operating system
- Processing version
- Any other important details to reproduce the error.

I quoted this from your post:

> Hi, this is an example to connect an Arduino-BLE33 Nano to _ **LINK REMOVED** _ and called TM\_Collector.  
> I want to transfer Image-data with the virtuell COM to the processing TM\_Connector application…  
> The library javax.xml.bind.DatatypeConverter of this application is imported in code but the Error says it does not exist…

_ **I removed the link because my browsers did not allow me to view it.** _  
There is a working link to a related GitHub topic in one of the references below.

Code provided:

```processing
import processing.serial.*;
import java.nio.ByteBuffer;
import java.nio.ByteOrder;
import websockets.*;
import javax.xml.bind.DatatypeConverter;
import controlP5.*;
import java.util.*;

```

You did not provide enough code to reproduce the error.

I will be using Processing 4.4.7 and Windows 10 for this discussion.

Related discussions:

- [Error with importing javax.xml.bind.DatatypeConverter](https://discourse.processing.org/t/error-with-importing-javax-xml-bind-datatypeconverter/43019)  
This is an example of incorrect formatting. _ **I do not copy and correct these.** _  
The solution does correct one error in the topic.

This appears to be the code you are using and I will use this in this topic.  
Keep in mind that this is an old post (almost 2 years ago) and may be a solution for the version of Processing used at that time.

Using code from last reference above I get this:

Note:  
The error in _RED_ did NOT appear right away and I had to scroll down and select it for details.  
Under the error there is code that is commented that _ **MAY** _ be a correction based on the some of the references listed and testing.  
_I was only testing so you have to scrutinize this and correct as required._

The warning in _ **BLUE** _ is something new… the code still ran.  
Research suggests it a warning and not typically a critical issue.  
I can’t comment or explore this further at this time.

And the sketch launched:

The details are important.

Have fun!
