kandi X-RAY | envelope Summary
Envelope is a configuration-driven framework for Apache Spark that makes it easy to develop Spark-based data processing pipelines. Envelope is simply a pre-made Spark application that implements many of the tasks commonly found in ETL pipelines. In many cases, Envelope allows large pipelines to be developed on Spark with no coding required. When custom code is needed, there are pluggable points in Envelope for core functionality to be extended. Envelope works in batch and streaming modes.

QUESTION
i am currently building a Client to communicate with a Gateway of a Charge Point.
The communication is build with OcppV1.5 over Soap & Http.
The Server doesn't accept my request. I get a Http Response 500 with the Error Reason:
"XML Request is not well formed, Action does not exist."
I looked into the wsdl files but I just don't understand why it doesn't accept my action.
My Request looks something like this:
...ANSWER
Answered 2021-Jun-13 at 09:11It's hard to tell from what you posted why you are getting an error, so I can only add some information that can hopefully allow you to troubleshoot the issue.
Your message has WS-Addressing headers, being one of them. The value of this field should be specified in the WSDL if your WSDL also includes WS-Addressing Metadata information, or should be specified in the documentation of the web service you are invoking. Your error message "XML Request is not well formed, Action does not exist" seems to indicate that there might be an issue with this field, but there is another action that SOAP services have which is a SOAP action. I asked about it in the comment above to make sure it's eliminated as a source of problems. In SOAP 1.1 it's called SOAPAction and is a separate HTTP header, while in SOAP 1.2 it's an action parameter on the HTTP Content-Type header. Based on the http://www.w3.org/2003/05/soap-envelope namespace, you have a SOAP 1.2 message.
With these explanations layed out, I suggest you take the WSDL and feed it to SoapUI who can generate sample requests that you can use to invoke the web service. If the WSDL also contains WS-Addressing Metadata, SoapUI should be able to pick it up and help you fill in the values you need. If not, look again through the WSDL for Action elements (make sure you differentiate between the SOAP Action and the WS-Addressing Action using their XML namespaces) or through the service documentation.
Once you get a succesfull call using SoapUI, then try to duplicate it with your code. At that point you can again use SoapUI to troubleshoot things and inspect your code built message to see it resembles the one you can successfully send with SoapUI.
Hope this helps get you closer to a resolution.
QUESTION
I am using WSO2 APIM 2.1.0 and IS 5.3.0
I'm currently trying to create an API that registers a certain user by calling the admin service UserInformationRecoveryService which gives out a custom JSON response if the creation is successful and another response if it is unsuccessful, in which case the user already exists.
So far I have written the in sequence and the out sequence as follows but I am having trouble getting the expected output.(The success response is always seen even when the user already exists. That is, the else block is getting executed in the out sequence.)
In Sequence

I built a python program that will siphon through my email and retrieve lat/long pairs of worksites that will be relevant for future analysis. At the moment I have the following dataframe returned.
...ANSWER
Answered 2021-Jun-14 at 15:40There is no pre-built way for your exact transformation, so you have to create your geometry objects yourself. I assume you meant one LineString object per row in in your DataFrame. With little typing, you could create such a column using the powerful apply method.
