我使用的是Jboss5.1、Tomcat 6、Ejb3.0
我试图从 Tomcat6 servlet 对部署在 Jboss5.1 上的远程无状态 bean 进行简单的 Ejb 远程调用。
我将所有必需的 jar 添加到 tomcat 库目录中。经过大量的努力，我在尝试查找时遇到了这个错误
那是异常(exception):

这是我的 tomcat 客户端:
public void setUp() throws Exception {
try {
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "192.168.200.32:1099"); // if not using
InitialContext context = new InitialContext(p);
// String lookupStr = "Mom/DispactherBeanRemote/remote";
String lookupStr = "DispactherBean/remote";
//System.out.println("lookup =" + context.lookup(lookupStr));
DispactherBeanRemote dispactherBean = (DispactherBeanRemote) context
.lookup(lookupStr);
// Object dispactherBean = context.lookup(lookupStr);
System.out.println("dispactherBean ="
+ dispactherBean.getClass().getCanonicalName());
} catch (Exception e) {
e.printStackTrace();
}
这是我的 ejb 无状态 bean 及其接口(interface):
Stateless
@Remote(
{ DispactherBeanRemote.class })
@RemoteBinding(jndiBinding = "DispactherBean")
public class DispactherBean implements DispactherBeanRemote, Serializable
{
...
}
@Remote
public interface DispactherBeanRemote
{
public MomDispatcherResponseMsgDTO dispatchMsg(MomDispatcherRequestMsgDTO momMessageRequestDTO);
}
谢谢， 射线。
最佳答案
需要将 ejb3 jar 添加到项目中才能解析对象。
关于java - 从 tomcat6 到 jboss5 的远程 ejb 调用导致 : Could not dereference object exception，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10431335/
