Add Module To Keel Software
Dec 27, 2014
Who has worked with keel software (open source)? KEEL is an open source (GPLv3) Java software tool to assess evolutionary algorithms for Data Mining problems including regression, classification, clustering, pattern mining and so on.
source code of keel software: [URL] ....
I want that add a algorithm to it. The algorithm is attachment. who sent it, said " In order to run this algorithm, you need to download KEEL software and copy the .jar files for the preprocessing approaches, i.e. SMOTE.jar, into an "exe" folder." but I don't know.

I have to design/develop a module in java eg. Login. This module can be accessed by multiple concurrent users say 200, 500, 800 etc.
How such type of modules can be designed in such a way that it can perform successfully.
What are the main concepts at code level / Infrastructure level which we should take care while designing such modules.

My project builds a war. In the war there is a jar A which provides the implementation I1 of interface I. I1 is injected in a JSF controller. There is an optional jar B which provides another implementation I2 of interface I. I2 has an higher priority than I1. Is there a possibilty to achieve when jar B is present in the war I2 is injected. I tried it with @Alternative on I2 with an entry in beans.xml as alternative in jar B without success. I1 is injected. Something like a priority would be necessary. Or probably I am on a wrong way and there's another one that fits for my use case?

I'm writing an enterprise application to familiarize myself with Glassfish 3.1.2 and EJB 3.1. I've created several local, stateless beans, and injected one into a JSF managed bean. The ejb and web modules compile fine, but when I launch the application with Glassfish I get the following startup error and the application does not deploy.
SEVERE: Exception while invoking class org.glassfish.ejb.startup.EjbDeployer prepare method
SEVERE: Exception while invoking class org.glassfish.javaee.full.deployment.EarDeployer prepare method
SEVERE: Exception while preparing the app
SEVERE: Unable to load the EJB module. DeploymentContext does not contain any EJB.
org.glassfish.deployment.common.DeploymentException: Unable to load the EJB module. DeploymentContext does not contain any EJB.
Check the archive to ensure correct packaging for D:DocumentsNetBeansProjectsTestdistgfdeployTestTest-war_war.
If you use EJB component annotations to define the EJB, and an ejb or web deployment descriptor is also used, please make sure that the deployment descriptor references a Java EE 5 or higher version schema, and that the metadata-complete attribute is not set to true, so the component annotations can be processed as expected :
