I want to make a very simple program in JavaFX. It goes like this:

The user inputs something into a TextField

The program displays the input on a label but on a different Scene

I was trying to consume a soap service in python with zeep. I've consumed several soap services with zeep as well. But for a particular soap service, a weird response in returning, unlike a well-organized dictionary.

My python code is below:

I have the following WSDL definition:

I am trying to convert JSON response into XML and then call SOAP API with payload. I managed to get JSON response without any trouble, but I am unable to convert it to XML. the problem is data has to be in format:

I am trying to test Estes Express Freight API and have ran into a problem. I have the request object set up (and get expected error response back) except for the commodity part. There wsdl does not include a direct match such as commodity, basecommodity, or full commodities in their request class but just give an item as object type.

I am currently learning about Mule ESB and I have a question bothering me. I created App with Frontend in React and Backend in Node.js and I would like my API to send data through ESB with it inserting some data from public SOAP API. Then data from REST API and SOAP API would be combined into one endpoint that my Frontend could use. Is that possible? Could someone recommend some place where I could read more about it? I went through documentation but couldn't find such case. I use for that PC version of Anypoint Studio

EDIT: There is actually one more public REST API from which I would like to combine data into my endpoint. So in total 3 API responses combined into one JSON response.

We are using the Quickbooks Web Connector (QBWC) with the Consolibyte Quickbooks PHP Dev Kit. We have had a QBWC job working with this software for 4 years without major issues; however, now we are adding an additional QBWC job to access a different QB company file and a different handler. Every time this job runs it gets an error "Response is not well-formed XML":

I'm reading an HTML file and need to pass it as a string parameter to a JSON call. The HTML has curly braces in it for css/styles. I was looking at this question, but mine is more around JSON special characters where that one was other escape characters. The file may also have [] characters.
