我最近在學習JavaEE 7。當我嘗試從單獨的jar文件注入ejb時遇到問題。如何從同一個應用程序中的另一個ejb文件注入EJB?
我的代碼是這樣
@Stateless
public class HelloService {
public String hello(String name) {
return "Hello " + name;
}
}
的HelloService的是independed項目,我把它發佈到glassfish4服務器作爲EJB文件。
然後,我有JSF項目,現在我只有一個支持bean
@Model
public class IndexBean {
@Inject
private HelloService helloService;
public String getName() {
return helloService.hello("World");
}
}
構建JSF項目後。我將它發佈到同一個glassfish4服務器。但在我的JSF項目中,它不能從其他jar文件注入HelloService bean。
我試圖在HelloService類中添加@Remote,但它仍然不能注入。
我有3個pom文件。
