Redis serialization prefixed with extra string

阅读更多关于 Redis serialization prefixed with extra string

问题 Camel-Redis's serializer is prefixing extra characters to message key. When I checked the DB, the message key shows something like.. "\xac\xed\x00\x05t\x00\x11test150827171118" As you can see, the string "\xac\xed\x00\x05t\x00\x11" is prefixed for key "test150827171118" . I tried two patterns, Firstly, I set the serializer in the registry directly. Registry.put("serializer", new StringRedisSerializer()); Second pattern is by setting in the RedisTemplate first. Then putting the redis template

I am trying to figure out throttling concepts in Camel. I have already seen Camel's route policy , but this works for number of inflight exchanges. My route is following: routeBuilders.add(new RouteBuilder() { @Override public void configure() throws Exception { from("rabbitmq://127.0.0.1:5672/abc?queue=a&username=XXX&password=XXX&autoAck=false&durable=true&exchangeType=direct&autoDelete=false") .to("rabbitmq://127.0.0.1:5672/abc?queue=b&username=XXX&password=XXX&autoAck=false&durable=true&exchangeType=direct&autoDelete=false"); } }); Now my use case is that I want to transfer say 2000

Camel http4 and url-encoded passwords being interpreted as separate arguments

阅读更多关于 Camel http4 and url-encoded passwords being interpreted as separate arguments

问题 We've got an Apache Camel (2.13.2) app that uses http4 to communicate with a webserver, using NTLM for auth. The endpoint is defined as (pseudo): ... .to("http4://thegreat.server.com/uri?authUsername=" + user + "&authPassword=" + pass + "&authenticationPreemptive=true&authMethod=NTLM&authDomain=DOMAIN&authHost=host") .to("otherEndpoint"); This works well as long as the pass variable contains "non-special" chars. However, if the pass contains for example "abcd&def" - Camel will intepret the

Administration and Monitoring of Apache-Camel routes in ServiceMix

阅读更多关于 Administration and Monitoring of Apache-Camel routes in ServiceMix

问题 Being a user of Camel and ServiceMix I frequently need to monitor those tools for development purposes. I mainly use JConsole to access MBeans from ServiceMix and Camel. It gives a few really helpful metrics for an ESB developer. I also use karaf (web)console to track my route and bundles status. Looking around StackOverflow I found an interesting link that explains how to setup Hyperic HQ for ServiceMix 4: Monitoring Servicemix with Hyperic HQ. Are they other tools you would consider worthy

difference between embedded and standalone activemq broker

阅读更多关于 difference between embedded and standalone activemq broker

I am using Spring for my application. I am wondering what differences there is between "embedded" ActiveMQ and "stand-alone" ActiveMQ. If I run ActiveMQ embedded, does thing mean remote clients can still connect up? Is my understand correct that embeded ActiveMQ means that ActiveMQ will start automatically when I start my Spring application, or is there some other meanings to it? For example Let's say I have deployed one application in system-A and deployed the same application in system-B.in the application I have configured embedded ActiveMQ broker through spring xml files with broker url as

Spring Integration: TCP Client/Server opening one client connection per server connection

阅读更多关于 Spring Integration: TCP Client/Server opening one client connection per server connection

I'm trying to implement a TCP client/server application with Spring Integration where I need to open one TCP client socket per incoming TCP server connection. Basically, I have a bunch of IoT devices that communicate with a backend server over raw TCP sockets. I need to implement extra features into the system. But the software on both the devices and the server are closed source so I can't do anything about that. So my thought was to place middleware between the devices and the server that will intercept this client/server communication and provide the added functionality. I'm using a
