Server secrets in config.xml using environment variables

Hey Albert, I can think of two options. one is when you build the image and the other is at container startup.In imageWhen you build your image, you can add a replace but then you'd have to build a new image when your password changes. That would look something like this:RUN xml ed -L -u /Config/Server/Properties/Property[@name='MyCustomProperty'] -v "${env:ENVPWD}" config.xmlBeware I found the above in one of my dockerfiles that I altered a bit, so this one I’m not sure works. You'd have to try:)In containerIf you want to do it in container then you can make your service method take it out of the env variables by just storing the environment name as the value of the property and making a function that reads that name and uses the java method to get the corresponding value. Something like:Bottom left you see the implementation of CustomREST test()  where I look in the config for the property MyConfigProperty. That has a value ENVPWD(bottom right). that environment variable is set befor

'Reuse Sockets' option in Service Definer Connection

Hey Marc,I don’t think its in the documentation. It should be in Connections | USoft Community but it isn’t.. I can give u a short description of what it does and Ill create a ticket for R&D to document this feature.For the Service Framework to communicate with the Rules Service it will create a socket connection. When you connect to a RulesService, with the port 7777 for example, your operating system will also use a port to communicate back to the Service Framework. Because these ports are limited (something in the 60k), and the ports are not released instantly by the operating system, it can occur that you cannot create a connection to the Rules Service because there is no temporary port available. This issue can occur when you handle a queue for example and there is a decent amount of connecting to the Rules Service. When you use the option “Reuse Sockets” the service definer will not let go of the Socket after its request is done. It will be kept in a pool for a little while.

Set custom header in REST response

Goodmorning Marc,When you create an instance of a ResponseBuilder you can add headers to it. However make sure that you return the Response and not the ResponseBuilder. You can do that by calling the build() method of the ResponseBuilder like the last line below.jakarta.ws.rs.core.Response.ResponseBuilder respBuilder = Response.status(200);respBuilder = respBuilder.header("MyHeader", "MyHeaderValue");respBuilder = respBuilder.entity("Happy new year");return respBuilder.build();Hope this is what you are looking for.

Strange Java error in service framework

Hey Marc,Your code is perfectly fine, but it’s the service definer that’s not cooperating. This issue is that you’re using a foreach construction that the service definer can’t handle at the moment. I can reproduce it with a simple string arrayString[] cars = {"Volvo", "BMW", "Ford", "Mazda"};for (String car : cars) { System.out.println(car);}I looked at the kafka documentation and saw that the ConsumerRecords has an iterator. Can you try to use it like that for now?org.apache.kafka.clients.consumer.ConsumerRecords<String, String> records = consumer.poll(100L);java.util.Iterator recordIterator = records.iterator();while(recordIterator.hasNext()){ org.apache.kafka.clients.consumer.ConsumerRecord<String, String> r = recordIterator.next(); // Do stuff with r}Kind regards,Gert

Generate Swagger for REST services?

Hey Marc, sadly at the moment we don't have a solution for creating an open api document. I had a quick look at swagger-core but for now I couldn't get it to generate a document.Kind regards,Gert

Service definer: After upgrade from 9.1 to 10: "No such class: javax.ws.rs.core.Response"

Hey Marc,  What you are seeing is indeed the result of dependency updates. Due to a trademark issue with Oracle, the javax.* package had to be renamed by the eclipse foundation. This means, when you've used the javax.* package, that the package needs to be renamed to jakarta.*. So in your example it should be jakarta.ws.rs.core.Response.I hope this answers your question.Kind regards,Gert Kommer
