Java 为注册表实例化服务器类时出现运行时异常
我在我的Ubuntu虚拟机上尝试了相同的程序，该程序甚至产生了正确的输出，但在Windows上它给出了一个奇怪的运行时异常： e:\java\rmi final>javac *.java e:\java\rmi final>rmic ServerImplement e:\java\rmi final>rmiregistry 20361 << BLANK , fine >> e:\java\rmi final>java ServerMain 20361 java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.lang.ClassNotFoundException: ServerImplement_Stub at sun.rmi.server.UnicastServerRef.oldDispatch(UnicastServerRef.java:396) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:250) at sun.rmi.transport.Transport$1.run(Transport.java:159) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:155) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:535) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:790) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:649) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(Unknown Source) at sun.rmi.transport.StreamRemoteCall.executeCall(Unknown Source) at sun.rmi.server.UnicastRef.invoke(Unknown Source) at sun.rmi.registry.RegistryImpl_Stub.rebind(Unknown Source) at java.rmi.Naming.rebind(Unknown Source) at ServerMain.main(ServerMain.java:9) Caused by: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.lang.ClassNotFoundException: ServerImplement_Stub at sun.rmi.registry.RegistryImpl_Skel.dispatch(Unknown Source) at sun.rmi.server.UnicastServerRef.oldDispatch(UnicastServerRef.java:386) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:250) at sun.rmi.transport.Transport$1.run(Transport.java:159) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:155) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:535) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:790) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:649) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.ClassNotFoundException: ServerImplement_Stub at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:247) at sun.rmi.server.LoaderHandler.loadClass(LoaderHandler.java:434) at sun.rmi.server.LoaderHandler.loadClass(LoaderHandler.java:165) at java.rmi.server.RMIClassLoader$2.loadClass(RMIClassLoader.java:620) at java.rmi.server.RMIClassLoader.loadClass(RMIClassLoader.java:247) at sun.rmi.server.MarshalInputStream.resolveClass(MarshalInputStream.java:197) at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1575) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1496) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1732) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) ... 12 more 在Ubuntu上： machine@ubuntu:~/rmi final$java ServerMain 20361 TestClass is uploaded on the server. on port 20361 machine@ubuntu：~/rmi最终$java ServerMain 20361 TestClass上载到服务器上。在20361端口Java 为注册表实例化服务器类时出现运行时异常,java,classpath,rmi,Java,Classpath,Rmi,我在我的Ubuntu虚拟机上尝试了相同的程序，该程序甚至产生了正确的输出，但在Windows上它给出了一个奇怪的运行时异常： e:\java\rmi final>javac *.java e:\java\rmi final>rmic ServerImplement e:\java\rmi final>rmiregistry 20361 << BLANK , fine >> e:\java\rmi final>java ServerMain 20361 java.rmi.Ser
您忘记指定
-cp在我的CLASSPATH环境变量中添加了一个“；”之后。愚蠢的问题。。x-（在我看来，代码与执行尝试位于同一目录中，因此不需要类路径，对吗？使用-cp.和-classpath.bt尝试没有成功。它仍然显示相同的错误：-/ machine@ubuntu:~/rmi final$java ServerMain 20361 TestClass is uploaded on the server. on port 20361
