本文介绍了EJB3调用期间发生错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经写了一个简单的Ejb程序，从

最后JndI配置。
当我运行客户端代码时，我得到以下错误。

注意：端口和地址是正确的：
安全屏幕截图
内部客户端
在war文件内的server.jar内
解决方案
嗯，你必须看起来更好的屏幕截图，因为它是清晰可见启用管理安全性 是CHECKED 。
所以您必须在RMI / IIOP入站传输配置中禁用SSL，或正确配置客户端使用SSL。
这样的东西：
< java_install_root> / bin / java
-classpath com.ibm .ws.ejb.thinclient_8.5.0.jar：其中list_of_your_application_jars_and_classes>
-Djava.naming.provider.url = iiop：//< your_application_server_machine_name>
-Dcom.ibm.SSL.ConfigURL = file：///home/user1/ssl.client.props
-Dcom.ibm.CORBA.ConfigURL = file：/// home / user1 / sas .client.props
< fully_qualified_class_name_to_run>
有关详细信息，请查看以下页面 - 运行IBM Thin Client for Enterprise JavaBeans（EJB）
更新
现在您在代码中有问题。您必须对非托管客户端使用 PortableRemoteObject.narrow 。
而不是：
对象lobj;尝试{InitialContext ctx = new InitialContext（props）;
lobj = ctx.lookup（checkName）;
if（lobj instanceof ITestEJBRemoteInterface）{//< #####这是问题
loEJB =（ITestEJBRemoteInterface）lobj;
}
使用：
lobj = initCtx.lookup（ejbJNDIName）;
loEJB =（ITestEJBRemoteInterface）javax.rmi.PortableRemoteObject.narrow（lobj，ITestEJBRemoteInterface.class）;
有关详细信息，请参阅如何查找EJB 3的远程接口而不使用依赖注入
I have written a simple Ejb program, by looking from
The files are

public interface ITestEJBRemoteInterface {
public boolean checkNames(String fsName);
}

public TestEJB() { }

public boolean checkNames(String fsName) {
boolean lboolNamePresent = false;
if(fsName != null)
{
lboolNamePresent = moListOfNames.contains(fsName);
}
return lboolNamePresent;
}
}

At the client side:
I have created the stub using createStub.bat of IBM.and that jar is imported at the client side.

e.printStackTrace();
}
}
}
My project structure and the imported libraries as in the below figure:
At the WAS side, setup steps are as below: Port
Installation Steps
Lastly JndI Configuration.
When I run the client code, I get the following error.

Inside server.jar inside war file
解决方案
Hmm, you have to look better on your screenshot, as it is clearly visible that Enable Administrative Security is CHECKED.
So you either have to disable SSL in the RMI/IIOP inbound transport configuration, or properly configure your client to use SSL.
Something like this:
<java_install_root>/bin/java
-classpath com.ibm.ws.ejb.thinclient_8.5.0.jar:<list_of_your_application_jars_and_classes>
-Djava.naming.provider.url=iiop://<your_application_server_machine_name>
-Dcom.ibm.SSL.ConfigURL=file:///home/user1/ssl.client.props
-Dcom.ibm.CORBA.ConfigURL=file:///home/user1/sas.client.props
<fully_qualified_class_name_to_run>
For details check the following page - Running the IBM Thin Client for Enterprise JavaBeans (EJB)
UPDATE
Now you have issue in the code. You have to use PortableRemoteObject.narrow for unmanaged clients.
Instead of:
Object lobj; try { InitialContext ctx = new InitialContext(props);
lobj = ctx.lookup("checkName");
if (lobj instanceof ITestEJBRemoteInterface) { // <##### this is the problem
loEJB = (ITestEJBRemoteInterface) lobj;
}
use:
lobj = initCtx.lookup(ejbJNDIName);
loEJB = (ITestEJBRemoteInterface) javax.rmi.PortableRemoteObject.narrow(lobj , ITestEJBRemoteInterface.class);
