No HTTP PATCH Support in Java 8, but get errors loading messages in Java17

[hgolov]

Hi All,

I'm new to Mirth, so please bear with me if I'm asking a silly question.

I'm trying to send a PATCH request to a server, but get the following error:

Wrapped java.net.ProtocolException: Invalid HTTP method: PATCH

When I tried with POST and I get a 405 Method Not Allowed.

I tried restarting the admin with Java17, but that throws other errors when right clicking the messages in order to repost. (There are other errors as well, but this is a showstopper right now)

I'm working on a MacBook

You're going to have to share quite a bit more information. What is the endpoint you're calling? What is the documentation say about the endpoint? Your local workstation is usually irrelevant. Please read https://forums.mirthproject.io/articles/177082-forum-etiquette. While GitHub is not the forums, that article has points that are relevant about how to ask for help.

Thank you so much for your reply and the pointer to the etiquette. I'll try to expand. You're also correct about it not being an issue with the Java version on my local machine.

OS: Ubuntu 22.04
Java: openjdk 11.0.22 2024-01-16
OpenJDK Runtime Environment (build 11.0.22+7-post-Ubuntu-0ubuntu222.04.1)
OpenJDK 64-Bit Server VM (build 11.0.22+7-post-Ubuntu-0ubuntu222.04.1, mixed mode, sharing)
Mirth: 4.2.0

As part of our integration, we need to post to Salesforce's Bulk API 2.0, as documented here:

https://developer.salesforce.com/docs/atlas.en-us.api_asynch.meta/api_asynch/walkthrough_upload_data.htm

It is a multistep process, and one of the steps requires a patch call.
I've searched extensively, both on the internet and on Mirth forums. Based on what I've found, I tried a couple of different approaches.

1. Send the call as a post, but add a 'X-HTTP-Method-Override', 'PATCH' header. This fails with a 405 Method not allowed from Salesforce.
2. Send the call as a PATCH. This fails with a Mirth error - unsupported method.

Method One Code:

function sendDataToSFUrl(destURL, dataToSend, contentType, reqMethod){
	let method = reqMethod ? reqMethod : "POST";
	logger.info('about to send to: ' + destURL + ' content type: ' + contentType + ' and the method: ' + method);
	var openBatchUrl = new java.net.URL(destURL);
	var conn = openBatchUrl.openConnection();
	conn.setDoOutput(true);
	conn.setDoInput(true);
	if(method === 'PATCH'){
		conn.setRequestProperty('X-HTTP-Method-Override', 'PATCH');
		conn.setRequestMethod('POST');
		logger.info('just set header for override and method to post');
		logger.info(conn.getRequestMethod());
	}
	else{
		conn.setRequestMethod(method);
	}
	conn.setRequestProperty("Content-length", dataToSend.length);
	conn.setRequestProperty("Content-type", contentType);
	conn.setRequestProperty("X-PrettyPrint", 1);
	let bearer = globalMap.get('bearer');
	conn.setRequestProperty("Authorization", "Bearer " + bearer);
	var outputStream = conn.getOutputStream();
	var outWriter = new java.io.OutputStreamWriter(outputStream);
	outWriter.write(dataToSend);
	outWriter.close();
	return conn;
}

Method Two Response:

(I don't have the full output, but from the log info)

Response Code 405, Method not allowed.

Please advise!

HttpURLConnection doesn't support the PATCH method, see. You'll need to use the Apache HttpComponents client or another HTTP client library to make PATCH calls.

Well, that is an excellent point. I need to stop reading stuff after a few vodka sodas.

[hgolov]

Thank you so much, I'll explore that option.
