For Patch method support, we have to add a property HttpUrlConnectorProvider.SET_METHOD_WORKAROUND which is eligible for Http URL Connector but this does not have support for Proxy method.
For Proxy support we have to go for JettyConnectorProvider or ApacheConnectorProvider, but these connector loses property SET_METHOD_WORKAROUND, and with this Patch support.
Is there any workaround or fix?

We use Kafka, Kafka connect and Schema-registry in our stack. Version is 2.8.1(Confluent 6.2.1).
We use Kafka connect's configs(key.converter and value.converter) with value: io.confluent.connect.avro.AvroConverter.
It registers a new schema for topics automatically. But there's an issue, AvroConverter doesn't specify subject-level compatibility for a new schema
and the error appears when we are trying to get config for the schema via REST API /config: Subject 'schema-value' does not have subject-level compatibility configured
If we specify the request parameter defaultToGlobal then global compatibility is returned. But it doesn't work for us because we cannot specify it in the request. We are using 3rd party UI: AKHQ.
How can I specify subject-level compatibility when registering a new schema via AvroConverter?
Last I checked, the only properties that can be provided to any of the Avro serializer configs that affect the Registry HTTP client are the url, whether to auto-register, and whether to use the latest schema version.
There's no property (or even method call) that sets either the subject level or global config during schema registration
You're welcome to check out the source code to verify this
But it doesn't work for us because we cannot specify it in the request. We are using 3rd party UI: AKHQ
Doesn't sound like a Connect problem. Create a PR for AKHQ project to fix the request
As of 2021-10-26, I used akhq 0.18.0 jar and confluent-6.2.0, the schema registry in akhq is working fine.
Note: I also used confluent-6.2.1, seeing exactly the same error. So, you may want to switch back to 6.2.0 to give a try.
P.S: using all only for my local dev env, VirtualBox, Ubuntu.
#OneCricketeer is correct.
There is no possibility to specify subject-level compatibility in AvroConverter unfortunately.
I see only two solutions:
Override AvroConverter to add property and functionality to send an additional request to API /config/{subject} after registering the schema.
Contribute to AKHQ to support defaultToGlobal parameter. But in this case, we also need to backport schema-registry RestClient. Github issue
The second solution is more preferable till the user would specify the compatibility level in the settings of the converter. Without this setting in the native AvroConverter, we have to use the custom converter for every client who writes a schema. And it makes a lot of effort.
For me, it looks strange why the client cannot set up the compatibility at the moment of registering the schema and has to use a different request for it.
We use zuul as an gateway to dispatch incoming requests to services.
When we upgraded from 1.0.0, we noticed two issues, one of which we got a workaround to.
The second issue is that in some of the incoming have encoded uris to deal with special characters in the request, e.g. ....rovi//45846 which needs to be changed to rovi%2F%2F45846 in order to pass in.
So for a rest uri like the following POST http://localhost:8902/contentservice/content/subscriptionPackages/624460160/channels/rovi%252F%252F45846
If I make this request directly to the service, it works correctly.
But if I route it through zuul as POST http://localhost:8765/contentservice/content/subscriptionPackages/624460160/channels/rovi%252F%252F45846 then it disappears.
Now if I take the % out it is passed in and treated as an error in the contentservice when I step through the content service front end controller (off course).
What has changed between spring cloud 1.0.0 to 1.0.1 in the zuul functionality to stop this from working. As it definitely was working in 1.0.0.
So the spring cloud team has fixed this in the snapshot releases and you can fixed more detail here

I just tried to do a attempted a seamless upgrade of a service in a test setup. The service is being accessed by a Feign client. And naively I was under the impression that with multiple instances available of the service, the client would retry another instance if it failed to connect to one.
That, however, did not happen. But I cannot find any mention of how Feign in Spring Cloud is supposed to be configured to do this? Although I have seen mentions of it supporting it (as opposed to using RestTemplate where you would use something like Spring Retry?)
If you are using ribbon you can set properties similar to the following (substituting "localapp" for your serviceid):
localapp.ribbon.MaxAutoRetries=5
localapp.ribbon.MaxAutoRetriesNextServer=5
localapp.ribbon.OkToRetryOnAllOperations=true
ps underneath Feign has a Retryer interface, which was made to support things like Ribbon.
https://github.com/Netflix/feign/blob/master/core/src/main/java/feign/Retryer.java
see if property works - OkToRetryOnAllOperations: true

I have to implement a simple client to a XDS.b server (SubmitObjectRequest and RetrieveDocumentSetRequest operations), but I'm struggling to get even a simple example of use to work.
I've tried using Mirth Connect's Channel for XDS.b also, but with no use. I even tried to copy its SOAP envelope to use with SoapUI. Didn't work.
I'm using HIEOS deployed on Glassfish as my XDS.b server.
I'm lost and confused. Could anyone give me a guidance on how to make this work?
If the HIEOS is deployed correctly within the Glassfish the service endpoint provides a wsdl definition where the interface is specified. Check the Glassfish for the wsdl of the service.
http://localhost:8080/my-ws/simple?WSDL
Quelle: docs.oracle.com/cd/E18930_01/html/821-2418/gbiyw.html
The list of provided endpoints you can see here:
https://kenai.com/projects/hieos/pages/WebServices
So to retrieve the wsdl you should use for example:
http://localhost:8080/axis2/services/xdsrepositoryb?wsdl
which applies for the ProvideAndRegisterDocumentSet-b transaction of the XDS Repository actor.
You can use the WSDL definition to create a WS request using SOAP UI at first.
SOAP UI creates a request based upon the wsdl definition which can be used to
test a against your XDS repo.
When you know how a SOAP request must be constructed you can try it using Mirth or
create your own client using Apache CXF http://cxf.apache.org/ for example.
Or you use AXIS2 to create a client from the WSDL. Of course does Visual Studio and C# also offer mechanisms to create a WS client directly from a WSDL definition.
How can I only allow requests from my Apache Server in the DMZ access to WildFly over AJP, and block everything else?
This answer works great at deployment level but I would prefer control at the server-level :
At the moment only way to do this is by implementing ServletExtension and add extra handlers that will take care of that.
see http://undertow.io/documentation/servlet/servlet-extensions.html for more on writing extensions
and example of using it:
https://github.com/undertow-io/undertow/blob/master/core/src/test/java/io/undertow/server/handlers/IPAddressAccessControlHandlerUnitTestCase.java
In any case I would encourage you to create new feature request in undertow jira to add proper support for this. Issue tracker can be found at: https://issues.jboss.org/browse/UNDERTOW
