I would like to understand if the principles behind the Reactive Application manifesto can be achieved using a non-functional language . Some people say that since FP use immutable states and free side-effects functions, they are easier to implement concurrent, distributed and resilient systems. But how can we achieve that using Java for example? There are some frameworks like Apache Camel, that have some components to work with, like Camel RX , and Camel SEDA . Are these frameworks enough? I will try to clarify my question: I think of reactive programming as new programming paradigm, and a

i spent almost two days to understand the concept concurrentConsumers vs threads in Apache Camel. but i really don't understand the concept. could anyone help me to understand the concept. I am using camel 2.12.0. from("jms:queue:start?concurrentConsumers=5") .threads(3, 3, "replyThread") .bean(new SomeBean()); pom.xml ========================================== <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <camel.version>2.12.0</camel.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.8.1<

jetty expert, I got error when getting back large data via camel-jetty as http proxy, any experience/idea/suggestion are welcome, thanks in advance.

I'm trying to configure Apache Camel in Spring in the Java config way as detailed in this example . However I'm stuck at the dependency step because BundleContextAware and (transitively) BundleContext cannot be resolved. It seems that the necessary transitive dependencies are not downloaded. Here is my pom.xml: <properties> <apache.camel.version>2.9.0</apache.camel.version> </properties> <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-core</artifactId> <version>${apache.camel.version}</version> </dependency> <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel

I'd like to be able to do HTTP requests on my localhost Camel instance (just for development purpose, I know this is bad practice). For now, I'm stuck with : Origin http://localhost:8000 is not allowed by Access-Control-Allow-Origin. I've search how can I tell Camel to allow such requests, but didn't find an answer. I'm using camel-cxf and the rsServer to create my endpoint. I've got an endpoint looking like that : public class LoginEndpoint { @GET @Path(LOGIN) @Produces(MediaType.APPLICATION_JSON) public Customer login(@QueryParam("email") String email, @QueryParam("password") String password

Guys I am using Apache Camel to read data from mysql table. I am successfully printing it on console. But according to my requirement I need to read the data from one mysql database, then filter it by using some condition and then insert the filtered data in another mysql database table. I am posting my code below.. public class camelJdbc { public static void main(String[] args) throws Exception { final String url = "jdbc:mysql://localhost:3306/emp"; final String url1 = "jdbc:mysql://localhost:3306/emp1"; DataSource dataSource = setupDataSource(url); DataSource dataSource1 = setupDataSource1

I have the following strange (or at least unclear to me) behaviour for a multi-cast + aggregation. Consider the following route: from("direct:multicaster") .multicast() .to("direct:A", "direct:B") .aggregationStrategy(new AggregationStrategy() { @Override public Exchange aggregate(Exchange oldExchange, Exchange newExchange) { if (oldExchange == null) { List firstResult = newExchange.getIn().getBody(List.class); newExchange.getIn().setBody(ImmutableList.copyOf(firstResult)); return newExchange; } else { List oldResults = oldExchange.getIn().getBody(List.class); List newResults = newExchange

I have an authorization server [Simple Class annotated with @SpringBootApplication , @RestController , @Configuration , @EnableAuthorizationServer & oauth2 security] running on port 8081 which works fine & provides the access token when requested from POSTMAN using POST method along with needful parameters in the form of key value pair, http://localhost:8080/oauth/token , but how should i implement the camel route in java to get the access token by passing parameters in body ? This question is more about sending multipart/form-data with Apache Camel. I was playing with it some time ago and
