问题 I'm trying to write simple Storm + Camel project. My Storm topology analyzes tweets and one bolt should send tweet text to apache camel route, which in turn is using websocket to notify some webapp. I cannot make it work due to NotSerializableExceptions received from bolts when trying to use build once CamelContext. What I've already tried: pass CamelContext in bolt's constructor - results in NotSerializableException pass CamelContext in storm conf, and use it in bolt's prepare(...) method to

问题 I'm new in camel world and I have problems making a connection with the jcr component. look at my test code: import org.apache.camel.builder.RouteBuilder; import org.apache.camel.component.jcr.JcrConstants; import org.apache.camel.test.junit4.CamelTestSupport; import org.junit.Test; public class ObjectToJCRRouteTest extends CamelTestSupport { @Override protected RouteBuilder createRouteBuilder() throws Exception { return new RouteBuilder() { @Override public void configure() throws Exception

问题 Since I have to mock a static method, I am using Power Mock to test my application. My application uses * Camel 2.1 *2. I define routes in XML that is read by camel-spring context. There were no issues when Junit alone was used for testing. While using power mock, I get the error listed at the end of the post. I have also listed the XML used. Camel is unable to recognize any of its tags when power mock is used. I wonder whether the byte-level manipulation done by power mock to mock static

问题 I am trying to put a message on a Queue in Weblogic JMS, via a Camel Route. My aim is to eventually configure a Route to consume the messages from the jms queue to which I publish the data from the earlier Route. Here is my config: <bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate"> <property name="environment"> <props> <prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop> <prop key="java.naming.provider.url">t3://localhost:7001</prop> <!--

问题 I have a list of messages in activemq queue. each message has a custom header property with value. How I should be able to access only those messages whose custom header property value = 123.? I am using something like below to pick a message from queue. How to pick all messages which or a single message which has customHeaderProperty =123.? ConsumerTemplate consumerTemplate = camelContext.createConsumerTemplate(); Exchange ex = consumerTemplate.receive("activemq:queueName",10000); String

问题 I have several routes that looks like : from("quartz://" + getJobId() + "?cron=" + cronExpression + "&stateful=true") .routeId(getJobId()) .autoStartup(false) .to(getRouteTo()); Those routes can be started and stopped from an administration console. The problem I have is the following: If a route is configured to run everyday at 17:00, currently if my route is started after 17:00, quartz notice that it should have run at 17:00 and will try to recover that missed execution. I don't want that

问题 I was trwing to construct a synchronous route with timeout using Apache Camel, and I couldn't find anything in the framework with resolve it. So I decided to build a process with make it for me. public class TimeOutProcessor implements Processor { private String route; private Integer timeout; public TimeOutProcessor(String route, Integer timeout) { this.route = route; this.timeout = timeout; } @Override public void process(Exchange exchange) throws Exception { ExecutorService executor =

问题 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>

问题 I am exposing a rest service using "CamelHttpTransportServlet" that receive orders and place in jms queue. The code works fine on happy path and returns 200 response. I have written Processor to validate the input JSON, and set http_response_code based on the input. The issue is - for invalid requests though failure response code - 400 is set, the flow continues to the next route and pushes the data to the queue instead of sending the 400 response back to the calling app. rest("

问题 I am parsing a CSV file, splitting it and routing it through multiple processors in camel. There are two endpoints , one having erroneous data while other has validated data. I need suggestion in aggregating the data. Let's say the CSV file has 10 records out of which 6 reached one endpoint while 4 reached to another. How can I know if all 10 has completed from the file at each endpoint and move ahead of aggregator. I need to create two files one with valid data and other with corrupt data
