Javax Client.WebTarget: Issue creating The Request Body to support the content-type of multipart/form-data

Trying to write a ClientBuilder based method (Java/selenium tool) that handles the following condition: The Request Body for this api should be of type multipart/form-data and it should have a boundary differentiated between file attached to form and form fields

I have done the mutli Part Content in c# but the group needs to be written in Java. Here's the c# code that works for creating the request body. I just having some mental blocks writting the Java HTTP Client version (could not find any realistic samples out there)

Note: I trying to upload an application/msi or application/ms-dos-exec file via the form. Here's my c# code

		 MultipartFormDataContent multiPartContent = new
		 MultipartFormDataContent("----WebKitFormBoundaryliUiaMuaEcUBLr3A"); ByteArrayContent byteArrayContent = new
		 ByteArrayContent(LogoRequest.Content); byteArrayContent.Headers.Add("Content-Type", "image/png"); String
		 FileName = LogoRequest.Name; String ContentDispositionStr = "form-data; name=" + "\"logoImageFile\"" +"; " +
		 "filename=" + FileName; byteArrayContent.Headers.Add("Content-Disposition", ContentDispositionStr);
		 multiPartContent.Add(byteArrayContent); requestMessage.Content = multiPartContent;
