Question

我正在尝试创建一个基于SOAP的Web服务，它将在其他项目中调用无状态EJB。我的配置是Server：WAS 8.5，IDE：RAD 8.5，Java 1.6，EJB 3.1和SOAP 1.1。当我编写一个简单的添加方法时，它正确创建Web服务，WSDL，我可以访问Web服务。但是，当我添加另一个调用EJB的方法时，它不允许我创建服务和WSDL，它会抛出错误弹出窗口：

wsgen期间发生错误。

error: compilation failed, errors should have been reported
warning: The apt tool and its associated API are planned to be
removed in the next major JDK release.  These features have been

    ....

这是我的代码，工作正常

public class Operations {
    public int addition(int x, int y){
        return x+y;
    }
    public String Greetings(String name){
        return "happy birthday"+name;
    }
}

当我添加

@EJB
    private transient StatusEJBBeanLocal statusEJBBeanLocal;
    public Product StatusFromProductId(int ProdutoID) {
        Product produto = null;
        produto = this.statusEJBBeanLocal.StatusFromProductId(ProdutoID);
        return produto;
    }

显示错误。请通过一些教程链接帮助我，或告诉我我的代码有什么问题，如何从Web服务调用EJB。提前谢谢。

SOAP Web服务不适用于EJB调用
