Question

我想使用EJB3规则会话从Java独立客户端执行Rule Execution Server的规则。

public class TestGameExecute {
public static void main(String[] args) {
    Map<String,Object> inputParameters = new HashMap<String, Object>();
    Map<String,Object> resMap = null;
    IlrEJB3SessionFactory ejbSF;
    IlrStatelessSession rs;

    Game game = new Game(10,3);
    inputParameters.put("GAME", game);
    Hashtable<String, String> jndiProperties = new Hashtable<String, String>();
    jndiProperties.put("java.naming.provider.url", "corbaloc:iiop:********");
    jndiProperties.put("java.naming.factory.initial", "com.ibm.websphere.naming.WsnInitialContextFactory");
    jndiProperties.put("java.naming.security.principal", "username");
    jndiProperties.put("java.naming.security.credentials", "password");



    try {
        ejbSF = new IlrEJB3SessionFactory(jndiProperties);
        ejbSF.setRemote(true);
        ejbSF.setStatelessRemoteJndiName("ilog.rules.res.session.impl.ejb3.IlrStatelessSessionRemote");
        rs = ejbSF.createStatelessSession();
        IlrSessionRequest request = ejbSF.createRequest();
        request.setRulesetPath(new IlrPath("/GAMLCDDRuleAppPhaseII/SiorkCDDRuleProject_PhaseII"));
        request.setInputParameters(inputParameters);
        request.setForceUptodate(true);
        request.setTraceEnabled(true);
        request.getTraceFilter().setInfoAllFilters(true);
        IlrSessionResponse response = rs.execute(request);
        resMap = response.getOutputParameters();
        Game retGame =(Game)resMap.get("GAME");
        System.out.println(retGame.getWinner());

    } catch (IlrSessionCreationException e) {
        e.printStackTrace();
    } catch (IlrSessionException e) {
        e.printStackTrace();
    }
}
}

我在下面收到此错误：

Answer 1

您的Java独立客户端“TestGameExecute”需要在其类路径上包含com.siork.cdd.Game，以便能够通过RMI解组此类的实例。

Answer 2

这是一个JDK问题。检查您的JDK版本，升级它，对我来说它应该是8.x

CORBA MARSHAL 0x4942f896，无法从底层桥读取值：ClassNotFoundException
