RMI Server Class not found

I am facing a problem when i am going to generate Stub and Skeleton using rmic command, but it gives the error that
Error: "class not found"
Please help me.its urgent.

Run rmic -depend to ensure that any classes referenced by the server classes are also compiled. Also, run rmic from inside the directory of your project beside the root of your package.
ie:
Work directory: work/
Classes are in: work/com/yourdomain/rmistuff/CoolServer.java
Then cd into directory work/ and run:
rmic -depend -verbose com.yourdomain.rmistuff.CoolServer
Try this and see what happens.

Not able to start the remote server - class not found exception

All,
I am quite new to RMI programming, although i am an experienced java programmer. I am facing a problem in starting the remote server program which i wrote for RMI. I am getting class not found exception for "stub" class eventhough the class is in the classpath.
Following is the error console:

Following are my classes:
MyRemoteInterface.java
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface MyRemoteInterface extends Remote {
public String[] getNames() throws RemoteException;
public class MyServerImplementation extends UnicastRemoteObject implements
MyRemoteInterface {
public MyServerImplementation()throws RemoteException{

public String[] getNames() throws RemoteException{

public static void main(String args[]) {
try {
// Create an object of the HelloWorldServer class.
MyRemoteInterface obj = new MyServerImplementation();
// Bind this object instance to the name "HelloServer".
Naming.rebind("rmi://localhost:1985/GetNames", obj);
System.out.println("GetNames bound in registry");
catch (Exception e) {
System.out.println("GetNames error: " + e.getMessage());
e.printStackTrace();
public class MyRMIClient {
*@param args*
public static void main(String[] args) {
try {
MyRemoteInterface remObj = (MyRemoteInterface) Naming.lookup("rmi://localhost:1985/GetNames");
System.out.println("Names are "+remObj.getNames());
catch(Exception e) {
System.out.println("Problem encountered accessing remote object "+e);
}

That's a remote exception coming from the registry. You need to learn to recognize remote exceptions and their source, it's a mjaor source of confusion in RMI.
In this case it's the registry that can't find the stub class.
The stub class needs to be in the CLASSPATH of (i) the Registry and (ii) the client as well. Ditto the remote interface; ditto any application classes it refers to, and so on until closure.
The easiest way to achieve (i) is to start it in the server's JVM, with LocateRegistry.createRegistry().

RMI stub class not found exception

Configuration:
OC4J Release 2
Windows 2000
* I get a stub class not found exception when the RMI server is instantiated.
* I compiled the implementation class using rmic and created a jar file containing the stub and skeleton classes. The jar file has been included in both the WEB-INF/lib and the <OC4J-home>/j2ee/home/lib directories.
* "TestServer" class (given below) is instantiated in a servlet init() method (the exception is thrown here).
* Following are file listings (with code):
Remote Interface ---> Test.java
Implementation class ---> TestImpl.java
TestServer.java
Test obj = new TestImpl();
Context ctx = new InitialContext();
ctx.rebind("TestService", obj);
Any help is appreciated.

Found the solution. Thanx.

Class not found: org.springframework.beans.factory.BeanCreationException

I am deploying an .ear file to an Oracle Application Server 10.1.2.0.2. In one container, it deploys correctly. In another conatiner on the same server and configured identically (or at least I believe), I try to deploy the same .ear file but I get the error:
Deployment failed: Nested exception
Resolution:
Base Exception:
com.evermind.server.rmi.OrionRemoteException
Class not found: org.springframework.beans.factory.BeanCreationException; nested exception is:
java.lang.ClassNotFoundException: org.springframework.beans.factory.BeanCreationException. Class not found: org.springframework.beans.factory.BeanCreationException; nested exception is:
java.lang.ClassNotFoundException: org.springframework.beans.factory.BeanCreationException
Anyone would have an idea why? Thanks in advance.

Greetings,
Your error implies that the classpath for the second deployment might be wrong. This cannot be the package if you are deploying an identical ear file. Can you look at the setup for the second container from the admin to see if there is an RMI connection configured incorrectly? Check your opmn.xml file for port info:
<port id="rmi" range="12401-12500"/>and check the server using netstat -a to see if the configured port is open for use before starting the OAS.

Class Not Found in Server Application

I have set up a basic server application. It contains three files namely
Arith.java (implements the Remote interface)
ArithImpl.java (implements Arith.java the server) and
ArithApp.java which is the client Application
All of these are in the same package. I have compiled all of these files and I execute the rmic ArithImpl command from within the ArithImpl.java file via Runtime.getRuntime.exec(...);
The stub and skeleton files are generated and still I get a class not found exception. I have checked the class path and these files are within the class path.
If anyone could help me I'd greatly appreciate it. Thanks

Java.rmi.UnmarshalException: skeleton class not found but required for clie

Hello everyone,
I am new to RMI and getting a strange exception. I am using Java 1.5.0_07 both on client and server. They are running on the same machine, the rmi registry is started inside the server application.
I am wondering why java complains about skeletons, I thought they are automatically created when using java 5.0?
Please have a look at the stacktrace below.
Thank you for your help.
Best Regards
Patric

Interesting Class Not Found Exception on Client Side of RMI

I am having trouble getting my client to start up using RMI. I am running my server on a linux platform and everything seems to be starting up just fine. Here is how I start the server:
WEBSITE=/home/ian/html
SOFTWARE=/home/ian/software
java -ea \
-cp $WEBSITE/BNS/classes/ \
-Djava.rmi.server.codebase=http://1.paturi.usher.ucsdsys.net/BNS/classes/ \
-Djava.security.policy=/home/ian/software/BNS/RMI.policy \
-DPREP=$SOFTWARE/prepped \
-DARCH=$SOFTWARE/output \
BNS.plumbing.Server $WEBSITE is my Apache Server home folder, which is running. However, now I move to a Windows machine and run IE or Firefox. I navigate to the Apache server and it comes up. Yet, when I try to logon to a client it tells me that the client is not inited.
Opening the Java Console reveals this error:
load: class BNS.plumbing.Client.class not found.
java.lang.ClassNotFoundException: BNS.plumbing.Client.class

BNS.plumbing.Client is not a Stub method. I have a ClientLiason class which provides the stub and it does not seem to have problem there. Also, when I simply navigate to [http://1.paturi.usher.ucsdsys.net/BNS/classes/BNS/plumbing/] the Client.class file is clearly there waiting to be used.
Here is what I run when starting server side to get the RMIRegistry (which has been started without a problem):
SessionHost sh = new SessionHost();
System.err.println("created an instance of "+ sh.getClass()+" as server");
Registry reg= LocateRegistry.getRegistry();
System.out.println(reg);
reg.rebind(Constants.serviceName, sh);
System.out.println(reg);
System.err.println(Constants.serviceName+" server ready.");I have played around with the Registry reg=LocateRegistry.getRegistry() line in particular. I have tried passing in "localhost" and "1.paturi.usher.ucsdsys.net" but all to no avail. Then latter is linux machine that I am using. It is a cluster server at UCSD. In order to access it I must first ssh into a UCSD machine and from there ssh into my machine (this is because it is not a full-fledged ip address, but part of UCSD's domain). I think this might have something to do with the trouble I have accessing the class file when I tried to get at them through a browser directed to my Apache Server.
I am not the greatest network guy, I know a lot more about programming and I am at my wits end here. I have searched everything I can think of, with little success. If anybody has any ideas or can even point me in the right direction it would be greatly appreciated.
Thanks!
Ian

I think your codebase annotation is being lost because Client.class is on the CLASSPATH of the Registry. There are two solutions:
1. Start the rmiregistry command in a directory other than the root of the package structure, e.g. /.
2. Use LocateRegistry.createRegistry() instead of getRegistry() in the server, and don't start the rmiregistry command at all.

Servlet class not found error deploying a WAR on Web Logic Server 8.1

I'm re-deploying an updated web application to a web logic server, but when I navigate to the login page of the web application to test it, I get a class not found error for my login servlet. I have both the web.xml and the weblogic.xml descriptors in my WEB-INF directory, and all of my compiled classes are in the WEB-INF/classes directory, is there something else I'm missing? Any help would be much appreciated.

Thanks for the response. Here's the web.xml file:
<?xml version="1.0" ?>

None of the classes are in a package (I know it's not the best idea, but I didn't write these, I'm just doing some updates). So the file structure is pretty much just WEB-INF/classes/
At the moment I've got a fix by just putting the entire project (not in any sort of archive) on the server itself instead of deploying it as a WAR, any thoughts on why the WAR isn't working would be much appreciated though.

Optional Package class reference at server startup...gives class not found

I have a enterprise app having a webservice..the webservice (servlet) gets instantiated on server startup…It has reference of a class which is an optional package
All the manifest entries are correctly added to the ear..manifest.mf..
When the servlet is initialized at startup.. gives me a class not found error…
However, the app works fine..this is just a one time error(whenever the app is deployed fresh..)..
Any help would be appreciated

Java.rmi.RemoteException: newServlets not found

I am developing a java servlet using J2EE 1.4 RI.
I have developed a new application called newServlets.ear. This application has a web component named Servlet1. When I click on Tools, Deploy I get the following error:
stop newServlets
running...
java.rmi.ServerException: RemoteException occured in server thread; nested exception is:
java.rmi.RemoteException: newServlets not found; nested exception is
javax.management.InstanceNotFoundException: newServlets not found at
com.sun.corba.se.internal.iiop.ShutdownUtilDelegate.mapSystemException(ShutdownUtilDelegate.java:61)
at javax.rmi.CORBA.Util.mapSystemException(Util.java:65)
at
org.omg.stub.com.sun.enterprise.tools.deployment.backend.JarInstaller_Stub.stop(Unknown Source)
The J2EE RI Verifier produces no failed tests or warnings.
I have no idea what is causing this. Each time this happens, the Command Prompt window that is running J2ee server displays the message:
Stop recieved
I have tried stopping and restarting both the j2ee server and deploytool, but this has not fixed the problem.
In my servlet, I would like to take information that has been entered into an HTML text field and add it to a MS Access database. I have the following code in my servlet to load the driver:
final String pathConnection="jdbc:odbc:"+dataBase;
con = null;
String driverName="sun.jdbc.odbc.JdbcOdbcDriver";
try{
try{
Class.forName(driverName);
System.out.println("OK");
catch (ClassNotFoundException e)
System.out.println(" ERROR : driver not found");
e.printStackTrace();
}//end inner try/catch
System.out.println("Drivers (DriverManager.getDrivers()) :");
con = DriverManager.getConnection(pathConnection, "", "");
}//end outer try block
catch (Exception e)
e.printStackTrace();
}//end outer catch
The following code is being used to enter the data into the database:
try {
stmt = con.prepareStatement(
"INSERT INTO User (emailAddress, passWord) VALUES (?, ?)");
stmt.setString(1, emAddress);
stmt.setString(2, passWord);
stmt.executeUpdate();
catch (SQLException e) {
System.err.println(e);
e.printStackTrace();
finally {
con.close();
Is it possible that something in the code above is causing the problem??
Please help!!
I am running J2EE 1.4 RI and J2SDK1.4.1_01 on Windows XP Professional.

java.rmi.ServerException: RemoteException occured in
server thread; nested exception is:
java.rmi.RemoteException: newServlets not found;
nested exception is
javax.management.InstanceNotFoundException:
newServlets not found at
I'm having a similar problem trying to deploy an EJB on the j2ee 1.4 ri. It appears to be some sort of JMX problem. I suspect it has something to do with having a wrong value somewhere in the sun-j2ee-ri.xml descriptor, but I haven't figured it out yet. If you have, can you let me know what you did to fix it?
Thanks,
Steve

"Java Class not found in classpath" Error in DESIGNER

Hello All,
I'm trying to connect in Designer using a JDBC connection to MS SQL Server 2008. As per the instructions, I updated my jdbc.sbo file with the path to the existing two JAR files. However, I still get the following error when I try and connect in Designer: "Java Class not found in classpath : C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\jdbc\Drivers\sqlsrv". Of course, this error includes the drive path with the location to my JAR files. Any help in resolving this nagging issue is very GREATLY appreciated. Also, if anyone needs it I can post a copy of the jdbc.sbo file to this thread.
Thank you,
Pankaj

Stratos,
Your suggestion didn't help. I tried to connect after restarting my machine and I still get the error. And, I've also tried adding a connection to MS SQL Server 2005 using this JDBC driver, and that didn't help either. Any other suggestions? Would it help to see my "jdbc.sbo" file? Thanks again for your and everyone else's help, and I look forward to your reply.
Regards,
Pankaj

Class not found in applet using 2 jar files

I have an applet which has been working for years as a stand alone or connecting directly to a derby database on my home server. I have just changed it to connect to MySQL on my ISP server via AJAX and PHP.
I am now getting a class not found error in my browser, probably because I'm stuffing up the class path.
The HTML I am using to call the applet is:
<applet code="AMJApp.class"
codebase="http://www.interactived.com/JMTalpha"
archive="AMJ014.jar,plugin.jar"
width="500"height="500"
MAYSCRIPT style="border-width:0;"
name="jsap" id="jsap"></applet>The AMJ014.jar contains the applet and supporting class files.
The error message is strange to me because it refers to a class I noticed on another web page but which has nothing to do with my applet. Anyway, the message in full is:
load: class NervousText.class not found.

Service Bus 12c Class not found 'oracle.tip.pc.services.functions.ExtFunc'

Hi,
Did anyone came across this issue with Class not being found for XSLT Function used in transformer on 12c OSB.
I'm using oraext:sequence-next-val and have configured as below:
namespace-uri:http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc
namespace-prefix: oraext
Not sure why at runtime I'm getting below error, as the same was working fine in 11g OSB Domain.
XML-22045: (Error) Extension function error: Class not found 'oracle.tip.pc.services.functions.ExtFunc'

Have you restarted servers after putting jar in $Domain_Home/lib directory? Also try after explicitly adding this jar in classpath by editing server startup script (startManagedWeblogic.cmd or .sh) or in domain env setting script (setDonainEnv.cmd or .sh) and restarting the servers.
Regards,
Anuj
