Java RMI and Server Crash
Hi,
I just want to know if there is a possibility to let the Clients of a rmi based Client-Server-archtiecture know, when a Server crashes.
The problem is, that the names are still bound in the rmi-registry of a server, but the server is not able to do that service, because of a crash.
Of course the client then gets an exception, but is there a way to let him know that befor a lookup call in the rmiregistry of the server?
Thx, for helping!
No.

Standard Java RMI and WLS5.1?
I would surmise that the problem you are seeing is the result of the fact
that we do not except standard Java RMI calls using the functionality in the
JDK. You must use the WebLogic implementation of RMI. It is exactly the
same in terms of APIs, but we have gone through and optimize the underlying
protocol.
Please see the documentation for more details.
We offer both RMI over IIOP and RMI over T3.
Thanks,

Hello,
I was trying to get a simple callback demo working using standard java
RMI and the WLS5.1. Unfortunately, although things seemed to compile
and launch smoothly, when the client started up and tried to talk to the
WLS I would get the following error:
weblogic.rmi.server.ExportException: A description for CallbackImpl was
found but it could not be read due to: [Failed to find a stub for [class
CallbackImpl] implements at least one interface [interface Callback]
which extends Remote.]
weblogic.rmi.StubNotFoundException: Failed to find a stub for [class
CallbackImpl] implements at least one interface [interface Callback]
which extends Remote.
I tried determining if this was a classpath problem, but all my efforts
kept producing this result.
On the flip side, if I retool my objects slightly in order to make them
use weblogic.rmi.*, then everything works perfectly.
Is there a tradeoff to using weblogic.rmi over java.rmi?
Also, does anyone have any ideas as to what might be causing my error
when using standard rmi?
Thanks so much in advance,

Does ATS load testing support Java RMI and T3 protocol?
Hi Experts,
Does ATS load testing support Java RMI and T3 protocol or EJB(J2EE)?
Thanks!Joseph,
Oracle Application Testing Suite is mainly used for testing of applications from a end user perspective and offers an intuitive capture/replay for web, Siebel, EBS, JDE, Fusion apps or SOA based application through WebServices WSDL imports.
The scripting environment (Oracle OpenScript) does not support script creation by recording JAVA RBI or T3 protocol as we lack a recorder for it, but the scrips are created as pure JAVA code so you could use the JAVA language to write a small RMI cor T3 client for your testing.
We have customers that have used Application Testing Suite to test non-UI based testing, like: JMS, FTP, Tuxedo and others, but it require a bit of coding.
Please let me know if you would like to know more or discuss your options

Java.rmi.ServerException: Server unavailable, please try later
I'm testing a service proxy in JDeveloper 10.1.3.1.
I'm using encryption and signing.
Now that I have the encryption/signing key loading, I get the following error:

Is this a failure of the RMI server on my side or is it a failure to connect to the service? Is the destination service sending this to me or just the transmission code?
It looks to me from the trace and the vagueness of the message that this is from the Oracle transmission code in the StreamingSender class, not a message received from the destination webservice. Would love some confirmation, though.

Question about Java RMI and Eclipse
I would like to create an application with which I can easily connect to a JAVA program, installed on a web server, through JAVA RMI. I have already created a ClientRMI.java and a ServerRMI.java and compiled them. The stubs also have been created properly.
When I run the application outside the Eclipse editor, everything works just fine! However, when I want to integrate the files into a bigger project in Eclipse... and starts running it, he tells me he can't find the stub class or something like that. I need to place this one in the classpath but I don't know how to do that in Eclipse? Could anyone help me with this problem?
Thanks!
This is the fault message I get:
no security manager: RMI class loader disabled)
D-meDo you have an idea of what the answer to our
question could be?I don't have much idea about the question myself. I was groping in the dark. :-)
Anyway, the project classpath settings and the external jars (or dependent projects) are a few things which could be experimented with. I'm afraid I couldn't be much help without having a look at what you are trying to do. :-(

Hello everybody...
I'm planing a school project regarding Peer-to-Peer networking using Java RMI technology. The general idea is to use a Java Applets (using a special security manager) which acts as a P2P client and uses RMI to communicate with other Clients. I think security would be no problem if I use signed Applets...
With this foundation I will be able to programm a chat or a multiplayer chess or whatever.
Do you think this concept is possible and realistic or are there any better solutions?
Thank you for your advice.
Best regards

Error in the Socket Communication between Java Client and VC++ Server
In my application, using Java Client to do socket bi-communication with VC++ Server, which is done by somebody else.
The error is after the application properly running one or two days, the VC++ Server cannot receive the messages passed by java Client, but at Java client, everything is the same, although using CheckError() after every print(), there is no exception thrown.
The JVM is jdk1.3.1, platform is Win2k Server.
The outputstream is PrintWriter().
Please help me to settle down this problem. Thanks in advance.I read some thread in the forum, and found somebody had the similar problem with me. Just want to know how to settle this problem.
In the client/server program. Client is a JAVA program and Server a
VC++ program. The connection works, and the problem appears after some time. The Client sends a lots of requests to Serverm, the server seems receive nothing. But at the same time, the server is able to send messages to Client. The Client also can get the messages and handle them. Don't understand why there this problem and why it appears when it wants.
The client is a Win2k platorm with JDK1.3.1 and the server is also a Win2K platform with VC++ 6.0.
In the Client, using:
inputFromServer = new BufferedReader(new InputStreamReader(socket.getInputStream()));
outputToServer = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
Hope can get your help. -

I ask that, because JDBC drivers (type-2) do use native code.

New @ RMI need help with java.rmi.UnmarshalException: error unmarshalling
Hi @ all out there,
I'm new with Java RMI and have to write a EventSystem for an college project where clients can subscribe to a topic and get notified when someone publishes a message to the subscribed topic.
At server-side I have a class called EventSystem that provides methods for subscribing and unsubscribing from topics, and also for posting messages (for publishers).
To subscribe i thought that the client must specify the topic and also itself ( means that a client calls in this way: obj.subscribe("mytopic", this).
The EventSystem handles a list of all clients, and whenever a new message is posted it goes trough all clients and invokes the handleMessage(String msg) method that all Clients have to provide.
On my local machine without RMi this concept works just great.
I now tried to get it working using RMI , but I get the following Exception when starting the client (the server starts fine) :

Hello guys, I'm currently doing research trying to conduct a performance evaluation on java rmi and corba. To do this I have built a chat application and a file transfer application using both technologies (java rmi and corba) I will be using sockets for the client/server communication, I am currently testing for, memory usage of the client application, average data throughput, total packets sent and lost and cpu times for both client and server, I'm still researching on the best possible way to conduct the test and would appreciate it if anyone could help me on what tools to use and ways to conduct this test, thanks...
I will be using sockets for the client/server communicationYou will be using RMI or Corba for the client/server communication actually.
I am currently testing for, memory usage of the client application, average data throughput, total packets sent and lost and cpu times for both client and serverYou should also test latency
I'm still researching on the best possible way to conduct the test and would appreciate it if anyone could help me on what tools to use and ways to conduct this test, thanks...You could probably automate it using JMeter. Very handy thing. You can write both the client and the server in Java, using either RMI/IIOP or IDLJ for the Corba part. No particular reason not to use RMI/IIOP that I can see, it's just a thin layer over the other, more or less, and it's much easier to program. -

AVRHi AV,
simple search in sdn may answer your question,
There are two type of Proxy's in ABAP and JAVA(Clinet and Server),
Clinet ABAP proxy used to send message from ANY SAP System to Integration server,in this case XI adapter not required .
Server ABAP proxy used to send messages from Intergration server to any SAP System,in this case XI Adapter required.
How to implement ABAP proxy comunication refer below link
http://wiki.sdn.sap.com/wiki/display/stage/ABAPproxyproviderimplementationand+testing
The sama way Client JAVA proxy used to send message to Integration sever from any Web Application ,
Server JAVA proxy used to send messages to any destination system ,in both cases XI adapter required.

Rebind Method and java.rmi.server.hostname
Hello,
We are trying to execute a server on the internet which is installed in a machine whose private IP address is 10.X.X.XX.
To access the server by internet, the IP address is 196.XXX.XXX.XX and is converted by NAT to the IP address 10.X.X.XX.
I start the server with the command:
java -Djava.rmi.server.hostname=196.XXX.XXX.XXX myServer
Also, and according some recommendation in this forum, we don't use the "rmiregistry" and instead we use the method:
Registry r = LocateRegistry.getRegistry(MYPORT);
r.rebind("MyServer", obj);
However,
And it takes about over 4 minutes for this app to execute the rebind method. Does anyone know why ?
If I start without java.rmi.server.hostname propert. it executes immediatelly, but then I can't access the server from outside firewall.
Am I missing something?
Any advice or idea?
Thanks
Gerardo
PS. I am using Java 1.4.1 under Linux Red Hat 9.0.I start the server with the command:
java -Djava.rmi.server.hostname=196.XXX.XXX.XXX myServerThe wait is probably due to your DNS setup. Is a client inside the firewall able to reverse-resolve a 196.xxx.xxx.xxx address?

Hi to all.
I have two classes.
The first is:
public class FatherBean implements Serializable {
public String name;
public int id;
/** Creates a new instance of ChildBean */
public FatherBean() {
this.name= null;
this.id = 0;
public String getName() {
return name;
public void setName(String name) {
this.name = name;
public int getId() {
return id;
public void setId(int id) {
this.id = id;
The second is :
public class ChildBean extends FatherBean implements Serializable {
public double number;
/** Creates a new instance of ChildBean */
public ChildBean() {
super();
this.number = 0.0;
public double getNumber() {
return number;
public void setNumber(double number) {
this.number = number;
A test client class implements the following method that is exposed as web service:
public java.util.Collection getBeans() {
java.util.Collection beans = new ArrayList();
ChildBean childBean1 = new ChildBean();
ChildBean childBean2 = new ChildBean();
childBean1.setId(100);
childBean1.setName("pippo");
childBean1.setNumber(3.9);
childBean2.setId(100000);
childBean2.setName("pluto");
childBean2.setNumber(4.7);
beans.add(childBean1);
beans.add(childBean2);
return beans;
When I invoke the web service to url:
http://localhost:8080/Prova
and invoke the correspondent method on jsp client, throws exception:
