Java.rmi.ServerError: A error occurred the server; nested exception is:

Hello Guys,
I'm getting the following error when calling a method of a normally
deployed facade session bean.
java.rmi.ServerError: A error occurred the server; nested exception is:
java.lang.AbstractMethodError
It's very confusing, it sometimes appear and sometimes the method is
invoked normally.
Thanks in advance for ur help.

That error means your are not running xserver process. Or, your ssh connection is not set-up to forward X-11 data.

Using Applets and RMI on WL6 - Error marshaling transport header; nested exception is: - java.io.EOFException

I have a project that I am porting from WL5.1 to WL6. It was working fine
in WL5.1
but cannot get it working in WL6. So, I went back to the HelloWorld
example to
see if I could get it working. The problem I am having is basically getting
applet to
talk to a server via RMI. The applet works fine alone and RMI works fine
alone.
I can't get the applet to talk to the server via RMI.
I am trying to get the "HelloWorld" applet example in WL6 working with RMI.
I previously had the same app working in WL5.1 with SP9 but cannot get it
working in WL6.
I am running WebLogic Server 6.0 with SP2.
I have registered a startup class in the WebLogic console
named "HelloServer". When starting up the server, it states
that the HelloImpl class has been registered as "HelloServer".
When starting up the client applet I get the following error:
java.rmi.MarshalException: Error marshaling transport header; nested
exception is:
java.io.EOFException
These are two different methods of looking up the same object.
The exception occurs at the "lookup" method call in both cases.
"myserver" is the name of my machine that WL is running on.
7001 is the port that WL is using.
Registry reg = LocateRegistry.getRegistry("myserver", 7001);
obj = (Hello)reg.lookup("HelloServer");
or...
obj = (Hello)weblogic.rmi.Naming.lookup("rmi://" +
getCodeBase().getHost() + ':' + port + "/HelloServer");
I previously ran this same program under WL5.1 SP9 and everything works
fine.
I defined the startupClass in the weblogic.properties file in WL5.1
Can anyone tell my what is causing this exception and how to correct the
problem?
Thanks

these methods for looking up RMI objects - you should use JNDI instead.

Invoke EJB methods from RMI client -- OutOfMemory error on the server

Each time I tried to invoke a method of my session bean, on the server I have an

And the client doesn't receive any answer !
Do you have an idea ?
(everything before seems OK - context, narrow, home.create() ...)

[b]Strange Java.rmi.ServerError[/b] (very Urgent)

I have a rmi application runninfg on one server (called 1), and web application accessing that application (running on JRUN 3.0) from onother server (called 2).
[ I am newly setting up this structure on another servers (fallback server).
Its working file in the existing servers (live server) ]
There is a perticular methode in a class for which i get the java.rmi.servererror nosuchmethodefound error. If i try any other methode it works fine. the erro only comes for that perticular methode.
I have check the class files (interface, implementation etc.) the methode is perfect and working on the other server.
There is no flow found in any code on any server (1 or 2).the code is perferct.
I can not fild the flaw so please help me its very urgent and criticle.
please help me on this

will the out of date interface or stub process other methodes and gives problem to perticular methode.
all other methodes in the class works fine its only that perticular methode gives me the problem.
I actualy recomplied every file and still the error is still there

RemoteException: 111 java.rmi.ServerError: Error occurred in server thread

Hi,
I'm just new to the RMI field of JAVA. I'm trying to write a program that import the math.jar file in the server side. And the client end can invoke the methods of math.jar and get the value.
I got the error messages as below:
RemoteException: 111 java.rmi.ServerError: Error occurred in server thread; nested exception is:
java.lang.NoClassDefFoundError: org/mathwhizz/Heron
It can work well if I use source classes(*.class) directly instead of importing math.jar. The failure only happened when I try to make use of jar file. Thus I guess my setup and configuration should be ok. Is there anything I should be very careful if I try to run RMI and import a jar file in the program of server side ?
Do I need to use JNLP and web start application in this issue?
I'm appreciated for your responses...thanks...
Sincerely,
Brandon

Error OCCURRED: Failed to connect to LiveCycle server via RMI. Make sure that the server is running

I have installed LifeCycle trial version .
and trying to convert pdf to rtf
using following initialization

connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_PASSWORD, "password");
//Create a ServiceClientFactory instance
ServiceClientFactory factory = ServiceClientFactory.createInstance(connectionProps);
but i am getting error like following though i have started jboss which is inside lifecycle folder by run.bat
ERROR IS:Error OCCURRED: Failed to connect to LiveCycle server via RMI. Make sure that the server is running and accessible to this client.

May be you could use "netstat" or other tools like "ActivePorts" to ensure that ports established are correct.
Also try if jnp://127.0.0.1:1099 works or not, if ports are correct.

Java.rmi.RemoteException: Protocol error reported by the card! why?

Hello,
I am currently trying to run the JCK 2.2.1 SecureRMIDemo using SmartCardIO instead of OCF, but getting an error:
java.rmi.RemoteException: Protocol error reported by the card
(in my last post I succesfully ran the RMIDemo using my SmartCardIO implementation, see http://forums.sun.com/thread.jspa?threadID=5405634&tstart=15)
So here is what I did:
- I succesfully loaded the server app (com.sun.javacard.samples.SecureRMIDemo) on the card without changes.
- I created an new accessor class: public class PINCardAccessor extends SmartCardIOAccessor (I wrote SmartCardIOAccessor for the RMIDemo, it should work fine as an accessor)
- The contents of PINCardAccessor class and SecureOCFCardAccessor are the same, just the class declration makes the difference
- Here is the most important part of my main method:
               ca = new PINCardAccessor(false);
               JavaCardRMIConnect jcRMI = new JavaCardRMIConnect(ca);
               jcRMI.selectApplet(appAID);
               // send PIN
               System.out.println("Sending PIN...");
            if (! ((PINCardAccessor) ca).authenticateUser( PRINCIPAL_APP_PROVIDER_ID ))
                 System.out.println("Wrong PIN!");
                 System.exit(0);
               Purse myServ = (Purse) jcRMI.getInitialReference();
               if(myServ == null)
                  throw new Exception("Received null instead of the initial ref");
               // print balance
               System.out.println("Balance: "+myServ.getBalance());And finally here is the debug output:

Oh, thanks for pointing at the JCRE Spec, it is very informative, but i still have not found the problem yet.
If i understand everything right, the communication's flow is
SecureClient <-> PINCardAccessor <-> SmartCardIOAccessor <-> MySecurityService <-> SecurePurseImpl (with help of SecurePurseApplet)
probably i made a mistake in a protocol of one or more layers.
- MySecurityService, SecurePurseImpl and SecurePurseApplet are EXACTLY the one's from com.sun.javacard.samples.SecureRMIDemo of JCDK 2.2.1, so there cant be any mistake (?).
- SmartCardIOAccessor worked fine in my RMIDemo tests, see http://forums.sun.com/thread.jspa?threadID=5405634&tstart=15 - there is also the implementation)
- SecureClient must be obviously correctly
so maybe it's something about PINCardAccessor? hmm...i havent found anything, but here is the complete code:

Error getting the server-side naming service functionality

Hi all,
we are currently setting up the CTS+ activity based transport scenario. Everything seems to be working fine, however, we have to import each transport twice...
Before I go into detail in the error we get I will first describe our landscape. All the configuration we did was done in debate with SAP.
We use the SAP Solution manager (ehp1 SP 4) as the CTS+ server as recommended by SAP and have an NWDI system of which we only use the components DTR and CBS (since CMS is not used anymore in the activity based transport). We have defined three logical ports/RFCs. CTSCONFIG points to the NWDI system. CTSDEPLOY is running on the java stack of the solution manager and is only used for portal content (=epa) transports. CTSDEPLOY_DI is pointing to the NWDI system and is used for all NWDI (=dip) changes. The NWDI is running ehp1 SP3.
In STMS I defined all the non-abap systems (and configured them to use CTSDEPLOY_DI) and created the following transport route:
upload system (IMP) -> DEV -> ACC -> QAS -> PRD
I first attached the used dependencies in a transport request (SAP_BUILDT, EP_BUILDT, etc) these imported just fine. Then I did the SCA files which contain our custom code. I extracted these from the assemble step on our current NWDI system which will be removed as soon as we switch to the new CTS+ environment.
When we import the transport into the runtime systems then we see the DTR and CBS be filled sucesfully for this specific system. However, the transport request itself always fails with errorcode 12 and the error is:
Error during export service registration: Error getting the server-side naming service functionality during getInitialContext opera
tion. com.sap.engine.services.jndi.persistent.exceptions.NamingException: Error getting the server-side naming service functionality during getInitialContext operation.
Error in execution of Web services CTSDEPLOY_DI , exception is cx_cts_file_import_failed
File import canceled
When we then reimport the same transport it will go the second time fine. This is no problem during the setup but will not be workable when we go live ofcourse. Is there anyone who had this issue before as well and have a solution for it?
Kind Regards,
Nico van der Linden...

Hello Nico,
I would need the java trace files to get more info on this issue, but you can start troubleshooting this error with these notes:
#1172252: CTS+, 'attach file': Troubleshooting Guide;
#1003674: Enhancement for non-ABAP systems in CTS;
#1155884: CTS+, configuration 'close coupling': Troubleshooting guide;
Pay special attention to parameter NON_ABAP_WBO_CLIENT, whether it's correctly set on your CTS+ system(s).
Note #1003674 is a must for any CTS+ systems to work properly, as well as having an updated version of the transport programs (tp and R3trans).
Lastly, note #1155884 goes through some JCoException exceptions that commonly take place during CTS+ transports. But again, you need to check the underlying trace files to find the root cause of your issue.
I hope this information helps.
Best regards,
Tomas Black

             // to get data to and from server
InputStream in = clientSocket.getInputStream(); < my error is here
                BufferedReader br = new BufferedReader(new InputStreamReader(in));
                OutputStream out = clientSocket.getOutputStream();
                PrintWriter pr = new PrintWriter(out, true);
            while(true)
                Worker w = new Worker(clientSocket);
                w.start();
            }   // End of while
        }// End of main()
}   // End of class

well, using my superb powers of reasoning and deduction, I can say that this is a lemon entry, watson. the line you kindly highlighted can potentially throw an IOException which you are not dealing with. deal with it

IPlanet 6.0 Error msg : The server is busy. Please try again later

Hello,
I am new in iPlanet use. I am using a Java Web application, which web interface is
implemented by Servlets & JSPs, and which is managed by an iPlanet Web server 6.0,
installed on an HP-UX 11i UNIX platform. It interacts with 2 Oracle databases
accessed via JDBC. A Microsoft Internet Explorer 5.05 browser is used to access the
web application via HTTP.
Sometimes (I am investigating to reproduce it systematically :-( ), I have the error msg
"The server is busy. Please try again later.". Where does it come from ? From HTTP
connections number ? From Oracle connections ? And how to avoid it ?
Thanks in advance,

Hi,
Do you have a web-server in front of the application server ?
regards,

An error occur on server. printing will be stopped.

we have crystal report for VS 2010 Version : 13
I have an issue regarding printing. when we print approx 200-300 pages, after printing near about 40 page, printing will be stopped with error "An error occured on server. Printing Will be stopped".
Please help us....

Use the search string 'printing stopped crystal net' in the search box in the top right corner. This will bring up a number of KBAs and other resources you want to consider. Also, make sure you are using Service pack 9.
