关于使用Wildfly 18的JNDI查找，我面临一个相当奇怪的行为。我有一个简单的EJB：
package com.getronics.ejb;
import javax.ejb.Remote;
import javax.ejb.Local;
import javax.ejb.Stateless;
@Stateless
@Local(ICalculadoraLocal.class)
public class CalculadoraBean implements ICalculadoraLocal {
public int suma(int a, int b){
return a+b;
}
}
使用简单的界面：
package com.getronics.ejb;
public interface ICalculadoraLocal{
int suma(int a, int b);
}
还有一个简单的JSP页面可以检出：
<html>
<body>
<%@ page import="java.util.Hashtable,javax.naming.*,com.getronics.ejb.*" %>
request: <%= request.getRequestURI()%><br>
<%
final Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES,"org.jboss.ejb.client.naming");
final Context context = new InitialContext(jndiProperties);
ICalculadoraLocal calculadora = (ICalculadoraLocal)context.lookup("java:app/ejb-0.0.0.0.0.1/CalculadoraBean!com.getronics.ejb.ICalculadoraLocal");
int suma = calculadora.suma(2,2);
%>
context: <%= context%></br>
2+2= <%=suma%>
</body>
</html>
这很好用：
request: /ejb/index.jsp
context: javax.naming.InitialContext@3e532295
2+2= 4
但是，当我尝试使用线程时，像这样：
<html>
<body>
<%@ page import="java.util.Hashtable,javax.naming.*,com.getronics.ejb.*" %>
request: <%= request.getRequestURI()%><br>
<%
new Thread() {
public void run() {
try {
final Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES,"org.jboss.ejb.client.naming");
final Context context = new InitialContext(jndiProperties);
ICalculadoraLocal calculadora = (ICalculadoraLocal)context.lookup("java:app/ejb-0.0.0.0.0.1/CalculadoraBean!com.getronics.ejb.ICalculadoraLocal");
int suma = calculadora.suma(2,2);
System.out.println("suma: " + suma);
} catch (Exception e) {
e.printStackTrace();
}
};
}.start();
%>
</body>
</html>
它抛出一个NameNotFoundException：
javax.naming.NameNotFoundException: java:app/ejb-0.0.0.0.0.1/CalculadoraBean!com.getronics.ejb.ICalculadoraLocal
关于为什么会发生这种情况的任何想法？
似乎使用“全局”而不是“应用”使它起作用：
ICalculadoraLocal calculadora = (ICalculadoraLocal)context.lookup("java:global/ear-0.0.0.0.0.1/ejb-0.0.0.0.0.1/CalculadoraBean!com.getronics.ejb.ICalculadoraLocal");
原因似乎是“ app”，“ module”和“ comp”的JNDI查找在规范中不适用于那些线程。
