When does the error occur? As you are registering the component with the rmiregistry or when you are running the client?

JMX operation java.rmi.UnmarshallException

When executing an operation via JMX using JConsole, I get the following error:
Problem invoking getManifest : java.rmi.UnmarshallException: Error unmarshalling return: nested is: java.lang.ClassNotFoundException: foo.bar.InernalServiceException (no security manager: RMI class loader disabled)
Code snippet:

Jbuilder, RMI, ServerException, UnmarshallException, CommitSuicideExc....

Hi Hero's
I have posted one message before about RMI and JBuilder, but no answers there.
I have browsed through following previous topics:
http://forum.java.sun.com/thread.jspa?forumID=58&threadID=142221
http://forum.java.sun.com/thread.jspa?forumID=58&threadID=272791
http://forum.java.sun.com/thread.jspa?forumID=58&threadID=399656
[and many more].
I figured out that JBuilder has some RMI support and I am now able to start the RMI registry inside JBuilder (JBuilder 2005) and I also managed to compile my stubs within JBuilder.
Still I receive this error message:
Trouble: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: root.CalculatorImpl_Stub
PLEASE HELP ME!!! I am getting fired over this.. well actually, that's not true, but this really is frustrating me!! ;-)
I will pay 10 Dukes if you help me! :)
Thanks in advance, Bas

Please help me a little bit further, but I still can NOT start my RMI server application!
1)
I have a project created in JBuilder. One java file should be remotely available (Handler.java). It is compiled with JBuilder and a ...stub.class is generated. [offcourse no compile errors occured]
2)
A dos box is opened. The classpath is set empty (set CLASSPATH=), and after that the rmi registry is started (rmiregistry).
3)
Another dos box is opened and the directory is changed to:
C:\test\rmi\rmiProject\classes
The java command is executed with the -D option for codebase and security policy (allowe everything).
C:\test\rmi\rmiProject\classes>java -Djava.rmi.server.codebase=file:/C:\test\rmi
\rmiProject\classes\rmiproject\server -Djava.security.policy=c:\test\java.policy
rmiproject.server.RmiServerApplication
An exception occured when binding Handler object: RemoteException occurred in se
rver thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested excep
tion is:
java.lang.ClassNotFoundException: rmiproject.server.Handler_Stub
java.rmi.ServerException: RemoteException occurred in server thread; nested exce
ption is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested excep
tion is:
java.lang.ClassNotFoundException: rmiproject.server.Handler_Stub
[and so on, and so on]
The -D option for codebase doesn't add anything at all. I tried almost everything, but it keeps resulting in an error, whether I add the option or not.
I also read the documentation about the codebase, but I still do not know how to solve this problem.
Who can help me!
Thanks

Java.rmi.UnmarshallException

Hi all,
I've been using a JUnit remote test client for testing my EJB methods. It was all working untill I got the below exception. I dont know the reason for such an exception. I know its nothing related to 'Serialization', as all my classes involved in remote calls are Serializable. Please share your views on that, if you've ever come across such an exception.
Thanks in advance....

Dynamic implementation download for return values from EJB

I try the following exemplary scenario regarding dynamic implementation download. Let's say there is a statless EJB deployed (e.g. OrderHandler) with a method getSomeOrder() returning Order object; where Order is actually an interface extending java.io.Serializable. For Order there is implementation class OrderImpl. Within the getSomeOrder() the EJB creates a new OrderImpl, populates it and returns as interface. The client looks up OrderHandler and calls getSomeOrder() method. Then, on Order a dummy: String getName() method is called.
Now, the problem is various behavior with implementation dynamic download. I receive different behavior from 2 clients (1st being launched from within LAN with the server, 2nd from outside server's LAN). When I put OrderImpl in clients' classpaths, obviously they both work the same. When I leave only Order interface (!!the very goal of the test - dynamic impl. download!!), only the 1st client still works. I measured times in milis, and it looks that the OrderImpl is really downloaded, as the first getSomeOrder() call lasts around 10 times as long as further calls.
The 2nd client hangs a while on the getSomeOrder() call and then throws UnmarshallException, stating that it has failed to unmarshal the returned object, which basically means no implementation got downloaded.
Can anyone help?

You can try putting the Impl classes on a webserver.
while starting the server set the property
-Djava.rmi.server.codebase=http://mywebserver:8080
While running the client if the impl classes are not available in the classpath, it would download it from the webserver

Plz suggest me on this problem

hey friends
##problem1
when i am working on my dos prompt to run my rmi programs
it provide the following error
RemoteException has occured in server thread; nested Exception is:
java.rmi.UnmarshallException:
while if i run this program to another machine it gives no error and work properly
it means there is something wrong with my dos setting but i am not able to detect it
plz give ur valuable suggestion
one more thing sometimes my j2sdk javac server compile classes but does not run class when i write java classname(it says class not found exception)
for this i try to increase my default buffer size 50 to 300 and then it was working fine but #problem 1 remain same as it is

It sounds like a classpath problem.
Try on dos command:
set path=.;C:\j2sdk1\bin
then enter
you may have to include -classpath . during your javac command as well

While the MalformedURLException doesn't seem to affect the functionality, I would like to get it resolved or at least know why it happens/if it can be ignored.
I have jmxremote_optional.jar on my classpath and can access the mbeans by connecting to jconsole with my service url.
Any insight as to how I can resolve this would be much appreciated.
Many thanks!

Logs for JConsole.

Hi All,
i have been facing an issue and i am unable to find its solution.
here it my problem.
i have configured JConsole for my application with Tomcat 6 and Jdk 1.6.
CATALINA_OPTS="-Dcom.sun.management.jmxremote \
-Djava.rmi.server.hostname=22.33.44.55 \
-Dcom.sun.management.jmxremote.port=8008 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=true \
-Dcom.sun.management.jmxremote.password.file=/usr/local/apache-tomcat-6.0.18/conf/jmxremote.password \
-Dcom.sun.management.jmxremote.access.file=/usr/local/apache-tomcat-6.0.18/conf/jmxremote.access"
Now when i use these settings on one server then i am able to access it through jconsole and i can view Jconsole and all memory related info. but when i put these settings on another server then i am unable to access Jcosole and its info and same case for 3rd server... i have checked and port is accessilbe from my server to 2nd and 3rd server. also i have checke with different ports but no sucess. :(...
but Yes, difference between 1st and 2nd,3rd servers is of data center. 1st server is placed onone data center and 2nd,3rd are on other datacenters, there is no other difference. No firewall issue. port is also not blocked.
now my question is that , is there any way to check it in logs? is any log being created for this activity that i can view to check to trace error.
Thanks.

Deployment problems, random exceptions

Hey,
We are having some problems getting our application to deploy. First of all the
context:
We are running Weblobic 6.0sp2 on jdk1.3.1_01 on a Windows platform.
We have an application consisting of 102 beans about 90 of those are Entity Beans,
the rest are Session beans. The beans are split up in separate components, about
15 of them. The components are ejbc-ed and deployed as separate jar 's. They
don't use remote relationships to connect between the components, but Home interfaces
in combination with finders.
To allow the components to be build and deployed separately, we put the util classes
and the home and remotes in the system classpath. That of course makes hot deployment
impossible, but we don't need to bundle the application into an ear file.
The deployment goes fine, but when we run the application we get 2 different exceptions.
These are NoSuchMethodException and UnMarshallException. Sometimes it 's the
first, sometimes the second, without even redeploying or rebuilding the application.
And they occur on different ( random ) places in the code.
Any help would be Extremely much appreciated,
Lieve

Thanks,
It works now. It 's crazy, but solves the problem.
Have a nice day,

Hello Lieve,
The problem is maybe related to naming. I had problems once with a jar
in the
system classpath, containing util classes, that was called base.jar
It seems that naming it differently solves the problem. If you name
it something
like base-<something>.jar, all the crazy problems will be solved. I
honestly
have no idea why or how this was happening, but it did.
Maybe this helps,

Hey again,
So we have looked at the problem in more depth, and it seems that it
goes wrong
the first time a home interface is used.
The lookup works fine, but the first time a home is used it gives a(seemingly)
random exception. The second time however it works fine.
Would anybody have an idea ? Thanks,

Invoking methods on JMX with user defined objects.

Hello, All.
Here is the problem description: We need to expose methods on JMX which takes some object of user defined class. We are not able to do that. Meaning, it is not getting enabled and if we invoke through code it says exception with serialization things. So we tried to make user defined class to implement serialization by making it to implement Serializable [though just adding serialization id]. But still we are getting the same problem. So I think we are missing some small step; as we are completely new this we are looking for some help in how to provide methods on jmx which accepts arguments of user defined type.
Thanks,
Prasanna.

Catching rmi serverException

hi.
my server is throwing an exception that extends remote exception. as i understand this means that a rmi server exception is being created with my exception as it cause.
i want to catch this exception before it is being throwed and only throw my exception, since i dont want my client to see this the serverException, just my exception.
any thoughts on how to handle this problem?
thanks alot!!!!

my server is throwing an exception that extends remote exception. as i understand this means that a rmi server exception is being created with my exception as it cause.No. It means that the server encountered either a RuntimeException or a RemoteException of its own, typically an UnmarshallException.
i want to catch this exception before it is being throwed and only throw my exceptionYou can do that in the case of a RuntimeException. Just add a try/catch block into your remote method body. In the other cases you can't, as they don't arise in your code.
since i dont want my client to see this the serverException, just my exception.Again you've misunderstood. The ServerException doesn't wrap the exceptions that your remote method is declared to throw: it is one of the possible RemoteExceptions that your remote method may throw in addition to your own.
It isn't clear from what you wrote, but if your 'my exception' extends RemoteException, that is a design mistake. Leave the RemoteExceptions for RMI and keep your own exceptions distinct.

Hi,
I need to access the method invocation times, availability, remove count, create count etc. of a deployed entity EJB through JMX MBean, in JBoss.
I have deployed the entity bean and the stateless DAO bean that operates on the entity bean. I do find an MBean for this DAO in the JMX-console of JBoss, but not an MBean for the entity EJB.
a) Why do I not find an MBean for the same?
b) How is it possible to get the MBean created for the entity EJB?
Speedy help solicited.
Thanks a bunch in advance guys !

When executing an operation via JMX using JConsole, I get the following error:
Problem invoking getManifest : java.rmi.UnmarshallException: Error unmarshalling return: nested is: java.lang.ClassNotFoundException: foo.bar.InernalServiceException (no security manager: RMI class loader disabled)
Code snippet:
public ArrayList getManifest(String s) throws InternalServiceException, MBeanException{
String path = ".\\foo_services.jar"; // Invalid path on purpose to test exception...
File file = new File(path);
FileInputStream fileInput;
try {
fileInput = new FileInputStream(file);
} catch (FileNotFoundException e) {
String msg = "The manifest file is not found in the given path";
if (logger.isErrorEnabled()) logger.error(msg);
throw new InternalServiceException(msg, ErrorConstants.JMX_FILE_NOT_FOUND);
If I throw new RuntimeException(msg, e) instead of InternalServiceException(msg, ErrorConstants.JMX_FILE_NOT_FOUND), it works and I get the appropriate exception.
What is the reason for this?

RMI - ClassNotFound for the Stub

Hi guys and thank you in advance for any help.
I have a simple RMI application. When I try to bind my remote object to the registry I am receiving an UnmarshallException caused by a ClassNotFoundException. My Stub.class and Skel.class are in the same directory as my implementation class.
I am relatively new to this stub. Can anyone shed any light on this?
Many thanks
Elliot

You may also look into setting the path to your stubs dynamically at the command prompt, with the -Djava.rmi.server.codebase=file:///<path_to_stubs>
or -Djava.rmi.server.codebase=c:\<path_to_stubs>
(for windows users)
