I'd like to start from the basics if I may please. I've read a few tutorial here and there and I've just created a test application with probably the simplest RPC calls you can possibly have (basically I want to use the RPC call to call a method to print a string). I'm using Eclipse and I've created a maven project, loosely based on this tutorial and the following ones but things are not working very well (forgive me but I'm new to vaadin and still learning java). This is the structure of my project, including packages (the structure is …

Hello, I have an arrayList that I want to emit and receive it in another bolt. So as suggested on another post here I used: the first bolt: collector.emit(new Values(listI)); the next bolt: public void execute(Tuple tuple) { ArrayList<Integer> i = (ArrayList<Integer>)tuple.getValue(0); .... } but instead of a size 4 list, I am getting a list with size 0. Any thoughts?

Hello, i am new to storm and stream data. I have implemented a sketch algorithm in java with maven. The algorithm has as an input a continuous stream of integers. The result is an array of integer frequencies and i want to run some queries on that array, but i don't have any idea how it will be done. Will it retrieve the result array from the topology and run on it from a java program?Will i use the maven sql plugin or something like Trident? Any kind of help would be extremely appreciated :)

I am trying to simplify Maven to use one POM to do both a 64 bit build and a 32 bit build. I have tried to separate the build into two separate executions however I am required to set the compilerExecutable tag specified by the maven-native-plugin to point to either the 32 bit cl.exe or the 64 bit cl.exe. Has anyone every done this before or know of a way to build two architectures in one project?
