Hi,
I had the same problem. In my machine, path was having jre1.1.7 before my jdk 1.4. So it was picking up from jre1.1.7.
Java was happy when I moved my jdk1.4 path to the beginning of the path variable.
Hope this helps you.

Java.rmi.ServerException: RuntimeException

Hi All,
i had an issue related to sockets.Please see the code below where am getting the following exception,
java.rmi.ServerException: RuntimeException; nested exception is:
java.lang.RuntimeException: java.io.EOFException
what my concern is while debugging am not getting this issue.

SocketObject sob = makeSocketObject(pFromFiles, pToFiles, pCorrStylesheets,

System.out.println("The byte length " + readBytes1.length);
ois.close();
oos.close();
s.close();
System.out.println("\n----------------The length of the bytes read first ----- "

Am getting the exception at this line in the above code

what cause it??
in my SetImpl.java i use wurfltags.jar

System.out.println(result);
catch(Exception e){}
return result;
and, i generate the wsdl file and deploy it successfully. but in the client
when i call the service it will be error.
the client code is:

System.out.println(result+"bb");
} catch (Exception ex) {
ex.printStackTrace();
when i run the testpricefetcher.java it will raise the above error infomation.
it spent 2 days for me to find the problem, but i cannot solve it.
i think it does matter with the wurfl package.because i doesnt use the method of the package in the SetImpl.java it will be ok. How to call the package?please give me a hand.

can you give me a hand!thank you

Java.rmi.ServerException: Internal Server Error (serialization error....)

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:
java.rmi.ServerException: Internal Server Error (serialization error: no serializer is registered for (class test.ChildBean, null))

java.lang.ClassNotFoundException: RMITest.myRMIInterfaceThe Registry can't find that class on its CLASSPATH.
Solution: do something about that. Either run the registry as a separate task with a suitable CLASSPATH setting, or run it in the server JVM via LocateRegistry.createRegistry().

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:
WARNING: Subject Key ID extension not found.Using BST Referencing scheme
java.rmi.ServerException:

Process exited.
Debugger disconnected from local process.
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.
Thanks for any help.

This error generally means there is trouble in the host file, or there is trouble with anti-virus software. Check this section of the support document that you came here from.
Unable to contact the iOS software update server gs.apple.com
Error 1004, 1013, 1638, 3014, 3194: These errors may be the result of the connection to gs.apple.com being redirected or blocked. Follow these steps to resolve these errors:
Install the latest version of iTunes.
Check security software. Ensure that communication to gs.apple.com is allowed. Follow this article for assistance with security software. iTunes for Windows: Troubleshooting security software issues.
Check the hosts file. The restore will fail if there is an active entry to redirect gs.apple.com. Follow iTunes: Advanced iTunes Store troubleshooting to edit the hosts file or revert to a default hosts file. See section "Blocked by configuration: (Mac OS X/Windows) > Rebuild network information".
Try to restore from another known-good computer and network.
If the errors persist on another computer, the device may need service.

The documents I am sending do contain special characters like maybe japanese or italian.

Sounds like the xml you are sending is not well-formed. Please start with simple xml documents to see if it works.

Trouble: java.rmi.ServerException:

Hi all,
I tried to execute the example given in Sun tutorial.
I am getting the following error
Trouble: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: CalculatorImpl_Stub
Thanks

Hi,
This exception means the client attempted to download a stub from the server and couldn't find it.
You can get this exception for a variety of reasons:
1) The server-side doesn't have the stub. This is done by running the rmic tool against the implementation of a remote Interface
2) The server doesn't store the stub where the client can find it. This may be due to setting the System property java.rmi.server.codebase incorrectly, or not at all.
3) The server doesn't serve ("export") the stub. The server must have rmiregistry runnning on the server, and must make sure the rmiregistry CANNOT see the exportable object via its CLASSPATH.
3) The client is looking in the wrong place for the stub.

Java.rmi.NoSuchObjectException problems

Hello,
After calling home.create() in my code, passing in primary key and
additional column data, when I call home.findByPrimaryKey (primkey)
followed by a call to one of the methods in the bean, I immediately get
a a java.rmi.NoSuchObjectException.
An exception is not thrown when calling home.findByPrimaryKey (primkey)
so it is safe to assume that a reference has been obtained to the bean
with the data I am looking for, correct? If so, why am I getting this
exception:
java.rmi.NoSuchObjectException: Bean with primary key: 'Pat Hardy' not
found in

etc.
etc.
etc.
Any ideas of what I might be doing wrong?
Thanks for your help in advance.

We had a similar problem, although I don't know if it was the same
thing. We are using WL 5.1, sp5, with Oracle 8.1.6.
I have a stateless session bean, which had a transactional attribute
of 'Supports'. It would call an entity bean with transactional attribute
of 'RequiresNew' for all methods. The session bean would do a finder
on the entity bean, and if it got an ObjectNotFoundException, it would
then create the entity bean with a call to home.create(id). Then, it would
call a business method on the entity bean.
For some reason, in the case where the session bean is called from within
a thread that already had a transaction started, the call to the entity
bean business method would hang, if an only if it had to create a new
bean first. If the finder of the bean succeeded, there would be no hang.
Sometimes, instead of hanging, it would return a NoSuchObjectException.
If the stateless bean were called outside of a transaction, would always
succeed, regardless.
So, my fix, was to set the transactional attribute for the stateless bean to
'NotSupported' for all methods. It now seems to work in all cases,
no more hangs or NoSuchObjectExceptions....
Is this expected behavior? Is this related to the same problem?
The BEA recomendations to use READ-COMMITTED are useless for
the case where you are running a clustered environment, and where you
need to have the bean deployed on all servers in the cluster for
fail-over reliability.....

I dont' know about the mapping to CHAR but we've managed to fix our nosuch
object problem.
BEA sent me this snippet:
The bug is as follows
In Oracle (8.0.5), if there is a primary key constraint AND you use an
isolation
level of SERIALIZABLE, an insert followed by an update in the same
transaction
fails. Specifically, the insert succeeds (to all outward indications),
but the update fails (the returned count is 0) after some number of
iterations.
What's the workaround? If the customer is not sharing the database with
any
other app or running it under a cluster, tell them to set the isolation
level to
read_committed. Serializable only slows them down without any added
benefit.
If clustering is on, and serializable behavior is deemed essential for
this
particular bean, maybe they can deploy the bean on only one of the
servers
to reduce it to the case above.
I set the isolation level on our beans to read_commited. Fixed theproblem
although we're using Oracle 8i not 8.0.5.

Well, it appears, that you cannot map a java.lang.String to a CHAR inOracle.
A java.lang.String can be mapped to a VARCHAR2.
Is this a bug?

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

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) :
