Rmi Cliaent-side Exceptions
Hi,
I'm trying a Rmi implementation. The server side classes-interface look to work properly, but when I try to refer to remote objects from my client, it throws the following exception:
java.rmi.UnmarshalException: error unmarshalling return; nested
exception is:
java.lang.ClassNotFoundException:
RmiImplementation.RiceviFileImp_Stub
I run the client with the command:
java
- Djava.rmi.server.codebase=file:/d:\RmiImplementation/ RmiClient.RmiClient
The server run on a NT 4.0 workstation, and the stub calss is
d:\RmiImplementation\RiceviFileImp_Stub.class
Thanks in advance
Fabio
Of course, the class is downloadble frm a server!!!
The matter is that on the su. web site, they write an example using an applet, that's a little different, since it's compiled on the server machine and just excecuted on the client side.
Do I have to do something different if I'm not implementing an Applet?

Hi,
I am getting following an error when i try to run rmi programs in unix platform.
Steps are followed
1.compilation successful(Interface,Client as well as Server)
2.rmic Server Implementation(Stub & skeleton are created successfully)
3.rmiregistry &
4.Java serverprogramname
I am getting an error at this stage.Please kindly let me know where i made mistakes.
Please give me sample program to understand the implementation of rmi in unix platform.
Note:The sample program i had tried in windows platform it was successful.
Please help me to come from this problem.
I am expecting eagerly from you at the earliest.
thanks®ards,
Manohar ManiHi,
Steps are followed
1.compilation successful(Interface,Client as well as
Server)
2.rmic Server Implementation(Stub & skeleton are
created successfully)2.5 Have you deployed the remote interfaces and stubs where the Registry and client can find them? (There are various ways to do this.)
I am getting an error at this stage.Please kindly let
me know where i made mistakes.The first mistake is not to state exactly what the error is and what line of code you get it on. We are not mind-readers (although we do try hard).
Please give me sample program to understand the
implementation of rmi in unix platform.There are samples provided with the JDK. -
RMI client-side - how to encrypt,decrypt in client-side
I write javacard RMI style. My problem is...
Source code below is work when it write in applet (card - side)
but in client-side (reader -side) I copy it to client - side code and test to run, if fail --> throw exception 0x3 - javacard.security.CryptoException.NO_SUCH_ALGORITHM
It seem to be "javacardx.crypto" and "javacard.security" is make for use in applet in card only. Did I misunderstand?
if it make for use in applet only, how is possible to do like this " card use privatekey to sign message and send to reader , reader use card's publickey to verify that card sign this signature or not."
or
"card use reader's publickey to encrypt message and send to reader, then reader use privatekey to decrypt message (reader authencate itself) "
because I can't do any of cipher , keybuilder in RMI-client side(reader)
Cipher.getInstance(Cipher.ALG_RSA_PKCS1,false);
it will throw nullPointerException
and if (change false to true)
Cipher.getInstance(Cipher.ALG_RSA_PKCS1,true);
throw exception 0x3 - javacard.security.CryptoException.NO_SUCH_ALGORITHM
after that I swap this line with
pri_key = (RSAPrivateKey) KeyBuilder.buildKey(KeyBuilder.TYPE_RSA_PRIVATE,KeyBuilder.LENGTH_RSA_512, false);
since it will do this first (i swap the line already) it also throw exception 0x3 - javacard.security.CryptoException.NO_SUCH_ALGORITHM
also be the same result with swap
kp = new KeyPair(KeyPair.ALG_RSA,(short)KeyBuilder.LENGTH_RSA_512 );
to a first line
it throw exception 0x3 - javacard.security.CryptoException.NO_SUCH_ALGORITHM
Please help me
RSAPrivateKey pri_key;
RSAPublicKey pub_key;
KeyPair kp;

but in client-side (reader -side) I copy it to client - side code and test to run, if fail --> throw
exception 0x3 - javacard.security.CryptoException.NO_SUCH_ALGORITHMYou can not share code between card and client. On the card use the classes of javacardx.crypto and on the client side those of javax.crypto and java.security.
It seem to be "javacardx.crypto" and "javacard.security" is make for use in applet in card only. That is right.
if it make for use in applet only, how is possible to
do like this " card use privatekey to sign message
and send to reader , reader use card's publickey to
verify that card sign this signature or not." or
"card use reader's publickey to encrypt message and
send to reader, then reader use privatekey to decrypt
message (reader authencate itself) "On each platform you have classes that provide the same cryptographic operations but the interface of these classes is different (because of the limitations of the java card platform).
because I can't do any of cipher , keybuilder in
RMI-client side(reader)Use the java.security.KeyFactory instead.
Cipher.getInstance(Cipher.ALG_RSA_PKCS1,false);
it will throw nullPointerException
and if (change false to true)
Cipher.getInstance(Cipher.ALG_RSA_PKCS1,true);
throw exception 0x3 -
javacard.security.CryptoException.NO_SUCH_ALGORITHMCryptographic support on java cards is optional. Not every card supports every algorithm. Try to use another algo.

Java.rmi.RemoteException: EJB Exception: while calling an EJB method,
Hi
I am getting below error while calling a stateless EJB method. There is some validation checks while performing ejb's modify() method and a RuntimeException is thrown in case of validation failure.The modify() method internally calls other stateless ejb as well.
The problem I'm facing is, instead of getting the expected RuntimeException in the Servlet, i am getting RemoteException. I am using WLS 9 MP1, all participating ejbs are stateless and i am using default transaction attributes(Supports) for these ejbs.
The interesting part is, at the ejb layer RuntimeException is thrown as expected, but this exception changed to RemoteException at the servlet's end where i am catching the ejb call exceptions.
I am new to WLS, please suggest/help me out of this exception.
Any help is truly appreciated.

Edited by: user10721298 on Feb 23, 2009 4:16 AMHi,
If i don't misunderstand, you are using the RuntimeException as an application exception, right?
Have you annotated it or denoted it in deployment descriptor?
Thanks,

I'm working on Ludwig's testcase.
Ludwig's testcase is based on read-only View Objects.
Is it also the case in your application ?
I was unable to reproduce with VOs based on EOs.
With read-only VOs, you can avoid the ArrayIndexOutOfBoundsException by setting the "Key Attribute" property for the PK of the Master VO.
See the ADF Developer's Guide, topic "7.9.3 What You May Need to Know About Enabling View Object Key Management for Read-Only View Objects"

Please, help in RMI UnmarshalException: nested exception is: EOFException
Good day,
I have a problem in sample program, similar like an Oracle oriinal in "Getting Started Usin Java RMI", identically on server and client sides. It correctly works in NetBeans IDE, but never alone, as JAR archive or java class, if I used java -jar or java -classpath command-line form. Fragment of the server code includes final check on correct read from remote object, it corrrectly works within NetBeans but cause UnmarshalException in same server side in independent launch form (WeatherBean - sample object, contains points to information about city name, weather description, temperathure an small "weather" icon, WeatherService - interface with one getWeatherInformation() function):
String serverObjectName = "WeatherService";
final int remotePort = 1099;
final String remoteHost = "localhost";
Registry registry = LocateRegistry.getRegistry(remoteHost);
WeatherService remoteObject = (WeatherService)
UnicastRemoteObject.exportObject(service, 0);
registry.rebind(serverObjectName, remoteObject);
//control export output
java.util.List<WeatherBean> list =
service.getWeatherInformation();
for (int i = 0; i < list.size(); i++) {
WeatherBean wb = list.get(i);
service.addTextWeatherString(wb.getCityName() + " " +
wb.getDescription() + " " + wb.getTemperature());
//back read exported object (cause error)
String[] regArr = registry.list();
java.util.List<String> regList = Arrays.asList(regArr);
if (regList.contains(serverObjectName)) {
Remote remote = registry.lookup(serverObjectName);
if (Proxy.isProxyClass(remote.getClass())) {
Proxy proxy = (Proxy) remote;
InvocationHandler invocationHandler =
Proxy.getInvocationHandler(proxy);
WeatherService weatherService = (WeatherService)
Proxy.newProxyInstance(
WeatherService.class.getClassLoader(),
new Class[] { WeatherService.class },
invocationHandler);
list = weatherService.getWeatherInformation();
for (int i = 0; i < list.size(); i++) {
WeatherBean wb = list.get(i);
service.addTextWeatherString(wb.getCityName() + " " +
wb.getDescription() + " " + wb.getTemperature());
}Starts with form java -jar WeatherServiceProj.jar (my project name) cause this error:

Great thanks for some little help,

Is this a java mapping or Graphical, If Java, you should not run into this issue as you dont load the nested XSD`s.

Hi all,
I have an RMI server and a number of clients that run on different machines. What I need to do is, implement the "observer" pattern. i.e.
in my case, not only the clients call the server, but also the server
must notify the registered clients when its state changes.
For that purpose, I suppose, that my clients must also be RMI servers.
My first question is, is that true what I suppose? Is there any other
way to implement asynchron client side callbacks with RMI?
My second question is, if it must be done so (clients are also RMI servers), how can I implement this? Server needs client interface jar
file, ans client needs server interface jar file at compile time.
(Important: I do not use any HTTP server from which I can load _Stub
classes at runtime)
I don't like this architecture at all and therefore think that there
may be better solutions. One solution may be to poll the state of the
server from the clients periodically, so that there is no need for
callbacks. But that is also not the perfect solution for me.
Can someone suggest anything else?
Any idea will be greatly appreciated!
Thank youHello guvener
Some time ago, I did exactly what you are thinking about. Here was the strategy.
1. There was a server program, sitting (obviously) on the server machine, where rmiserver was running. The server class had only a single public method for the calling routines to call.
2. That public method took, as a parameter, a transaction request. One possible transaction was, "Here is a message for another client." Another possible transaction was, "Listen out for a message for me." For example, a client would call the server with the "listen" transaction or with a "here's a message" transaction.
3. When the calling method requested a "listen" transaction, the server would enter a "wait" state until it received a message for that particular client.
4. To prevent blocking, there were three specific strategies:
(a) The client would call the server with a "listen" transaction in a separate thread.
(b) There was a "cancel" transaction that would allow a client to cancel its "listen" transaction with the server.
(c) There was a "close-down" transaction that would allow the server to tell the clients their "listen" transactions had been cancelled, as it was closing down.
This requires thorough and careful planning. However, once the classes are correctly planned, this strategy is elegant and simple and leads to only a small amount of coding. It's also flexible, without any restrictions on how many transactions a client could request at a time.
Do be careful to synchronize where applicable!
I hope this helps. -
Hi all.
Can anyone tell me why a ClassNotFoundException is thrown in the second Naming.rebind() ?
Thanks a lot.
import java.rmi.*;
import java.util.*;
public class MyServer {
public static void main(String args[]) {
try {
Remote AA = new Nulo( );
System.out.println("new Nulo - OK");
Naming.rebind("AA", AA);
System.out.println("rebind AA - OK");
RemoteExtension BB = new Lion( );
System.out.println("new BB - OK");
Naming.rebind("BB", BB); // java.lang.ClassNotFoundException: RemoteExtension
System.out.println("rebind BB - OK");
} catch(java.net.MalformedURLException e) {
System.out.println("MalformedURLException");
} catch (ServerException e) {
System.out.println("ServerException");
e.printStackTrace();
} catch (java.io.IOException e) {
// problem registering server
System.out.println("IOException");
System.out.println("Main thread dies");
class Nulo extends java.rmi.server.UnicastRemoteObject implements Remote {
Nulo () throws RemoteException {}
interface RemoteExtension extends Remote {}
class Lion extends java.rmi.server.UnicastRemoteObject implements RemoteExtension {
Lion() throws RemoteException {}
}That's not the problem since System.out.println("new BB - OK"); gets to execute well. Exception is thrown in Naming.rebind("BB", BB);Thanks.

RMI-server communicates oracle: Exception
Hallo everybody,
My task is:
- to implement in oracle Java stored procedure,
- to implement RMI server
- to load in oracle wrapper for Connection-object (ConnectionImpl), that has a reference at Connection (default oracle Connection), this ConnectionImpl-object will be passed to RMI-server, the RMI-server will call a method on this object.
- Stub and Skeleton of ConnectionImpl are on both sides available (inside of oracle (as .jar) and on RMI-server side).
First I start RMI-server. Then I call the stored procedure. It finds RMI-server, calls the method on RMI-server side, then RMI-server tries to call the method of ConnectionImpl with the following result:

I will be thankful for every tip, how I can resolve it.Its clear you have the java permission set to allow db Java to write to a socket, since the call to the RMI server works, but maybe you are missing the permission to allow db java to listen and/or read from a socket?

Client side handling of exceptions thrown by a webservice
I have a webservice that is deployed in Tomcat 5.5 running on Windows XP, Java version is 1.5, using jwsdp 1.5. My client, when run as an applet in a browser (have tried IE 6 and FireFox 1), seems to be unable to parse any exception thrown from the webservice. Instead the following exception is caught by the client:

If I run the client outside of a browser it catches the exception that is actually thrown by the webservice.
Is there possibly a problem with the java 5 plugin handling exceptions thrown by webservices?
I have not found any bug reports or forumn posts regarding this so any assistance would be greatly appreciated.

Hello Everyone,
I encountered the following errors during deployment using J2ee's Deployment Tool.
I have an Entity EJB called Books using Cloudscape as the database. When I clicked on 'Generate SQL Now' in Deployment Tool, I received the following errors. "java.rmi.ServerException, - nested exception - connecting to database - no suitable driver".
Prior to deployment I have j2ee server, cloudscape database up and running. Cloudscape has the following Driver Class - COM.core.RmiJdbcDriver, COM.cloudscape.core.RmiJdbcDriver 1.7.2. The Database JNDI name is jdbc/BooksInCloudscape. I tried to re-register the driver in j2ee and cloudscape, then brought both servers down and up with no luck. I have put c:\Books\classes in my CLASSPATH.
Could anyone please shed lights on this issue? Thanks in advance.I am having the EXACT SAME ISSUE. I've been to countless message boards and support sites to no avail (I'm assuming you are also working from EJB 2.1 Kick Start by Peter Thaggard.)
If you've resolved this issue from another source please update this posting any help would be greatly appreciated. I can't express how much time has been wasted on this simple connectivity issue. -
