Java.rmi.ServerException: Internal Server Error (deserialization error: XML

I am trying to transmit a document as a byte array to a web service using jax-rpc, and I get the following error:

The code looks like:
Client:
clientStub = (ContentWebServiceListenerIF_Stub)new ContentIndexService_Impl().
getContentWebServiceListenerIFPort();
clientStub._setProperty(Stub.ENDPOINT_ADDRESS_PROPERTY, endPoint);
obj = clientStub.receivexmldocument(cd.externalLink.contents,inxml);
Web Service:
public String receivexmldocument(byte docstream[],
String inxml
) throws RemoteException {
The wsdl looks like:
<message name="ContentWebServiceListenerIF_receivexmldocument">
<part name="arrayOfbyte_1" type="xsd:base64Binary"/>
<part name="String_2" type="xsd:string"/></message>
<operation name="receivexmldocument" parameterOrder="arrayOfbyte_1 String_2">
<input message="tns:ContentWebServiceListenerIF_receivexmldocument"/>
<output message="tns:ContentWebServiceListenerIF_receivexmldocumentResponse"/></operation>
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.

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: 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

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.

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.

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.

I have check that this exception occured when IMPL class's naming.rebind method called.
import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;
public class myRMIImpl extends UnicastRemoteObject implements myRMIInterface
public myRMIImpl(String name) throws RemoteException
super();
try
Naming.rebind(name, this);
catch(Exception e)
System.out.println("Exception occurred: " + e);
public java.util.Date getDate()
return new java.util.Date();
Can you help me how to solve this problem.
Note : my rmiregistry is running on 4999 port.
- Hiren Modi

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: Missing port information

when i call the service ,i got the error:

what cause it??
in my SetImpl.java i use wurfltags.jar
//SetImpl.java
package sys;

import java.net.*;
import java.util.*;
import net.sourceforge.wurfl.wurflapi.*;
public class SetImpl implements SetIF {

mom.wurflWebInit();
UAManager uam =mom.getUAManagerInstance();
result=uam.getDeviceIDFromUA("MOT-T720/05.08.41R MIB/2.0 Profile/MIDP-1.0 Configuration/CLDC-1.0");
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:
/////////StockPriceFetcher.java
package sys;
import javax.xml.rpc.*;
import com.sun.xml.rpc.client.*;
public final class StockPriceFetcher {
public static final String getdeviceid(String req,String endpoint) {

stub._setProperty(javax.xml.rpc.Stub.ENDPOINT_ADDRESS_PROPERTY,endpoint);
result = stub.getdeviceid(req);
} catch (Exception ex) {
ex.printStackTrace();
return result;
} // getLonNowItem

String result=StockPriceFetcher.getdeviceid("ball=5&srv=7&pcode=500001","http://192.152.251.224:8080/jaxrpc-sys/jaxrpc");
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: 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.
code comes here-----------------------------------------------
Socket s = null;
byte[] readBytes1 = null;
try {
s = new Socket(txControlServer, 7777);
SocketObject sob = makeSocketObject(pFromFiles, pToFiles, pCorrStylesheets,
pHTMLUtilityServer, pOrientation, pDocumentClassif, pClientInfo, pFormats,
pCorrCode, images);
ObjectOutputStream oos = new ObjectOutputStream(s.getOutputStream());
oos.writeObject(sob);
ObjectInputStream ois = new ObjectInputStream(s.getInputStream());
readBytes1 = ((SocketObject) ois.readObject()).getFileData();
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 ----- "

catch (Exception e) {
ExceptionUtil.wrap(e);
Am getting the exception at this line in the above code
ObjectInputStream ois = new ObjectInputStream(s.getInputStream());
Can any one help me out why this problem occurs and how to resolve.
Thanks in Advance,

Got a Deserialization Error

Hi, I get the following Deserialization error when I used a Custom defined class as a parameter in the Client class. I followed the rules stated in the JAX-RPC tutorial:
To be supported by JAX-RPC, an application class must conform to the following rules:
It must have a public default constructor.
It must not implement (either directly or indirectly) the java.rmi.Remote interface.
Its fields must be supported JAX-RPC types.
The class may contain public, private, or protected fields. For its value to be passed (or returned) during a remote call, a field must meet these requirements:
A public field cannot be final or transient.
A non-public field must have corresponding getter and setter methods.
And when I looked in the generated class files I saw that custom object's SOAPBuilder and SOAPSerializer classes were generated.
Also, the WSDL file thats generated included the custom object's information (member names) in the complexType section.

I am invoking my own webservice designed very similar to the DII Client Example in the JWSDP Tutorial. Basically the problem I have now is that I can't pass around any arrays or user-defined objects as Parameters from the client. I have put in lines to the config.xml to include the Integer array type and userdefined class. Is there any documentation on how to do this? I am trying to use an int[] as a parameter...
I keep getting a java.lang.Class cast exception:

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) :
