Hi I'm trying to run a java application that binds a class to the naming server, but i constantly get a ClassNotFoundException

then from eclipse I try to execute the server but get this error

I've read the RMI Java tutorial but still could not get it working...
As VM Arguments I've set this:
-Djava.rmi.server.codebase=file:${workspace_loc}/progInternet2008
please help me
(I'm using Java 6)

Run the rmiregisrty command from your /bin, /build, or /build/classes folder, whichever folder is the root of your built files.
I spent half a day trying to solve that same thing.

The exception is occurring because the rmiregistry application doesn't know where to load classes from. When you attempt to bind an object in the RMI registry, the registry downloads the class definition for that object. Some of the other answers are telling you to get around this by setting the classpath for the rmiregistry app so that it has the class definitions when it is started and doesn't need to download anything, but Sun's Java RMI tutorial explicitly says not to do this. I suspect this has the potential to cause conflicts between the version of the class in the registry and the class on the server.
The correct way to handle the problem is to set the java.rmi.server.codebase property as you were trying to do. The property requires that a directory path be terminated with a forward slash, like so:
-Djava.rmi.server.codebase=file:${workspace_loc}/progInternet2008/
You may also be having trouble if the ${workspace_loc} variable is a relative path and the rmiregistry application was not started in the same directory so the relative path is not correct for it. If you either make the path absolute, or start the rmiregistry in the appropriate directory, the ClassNotFoundException should go away. See the tutorial on the java.rmi.server.codebase property for a little more detailed information.

Okay I just overcame this problem. Make sure when you run rmiregistry that your CLASSPATH environment variable is set.
For example, you might have a script:
set CLASSPATH=[path to jdbc driver].jar
rmiregistry.exe
This was all I needed to get my lost classpath working. I'm not sure how to send -cp commandline to rmiregistry.exe. Its documentation is quite lacking.

I'm fairly certain that you'll have to start your RMI server using the same classpath as your application. I believe it takes the same parameters as java, i.e. -cp [your class path].

Close the cmd window where the rmiregistry was initially started.In a fresh cmd go to the location where your project classfiles are located(uptill bin) and start the registry using the below command:
rmiregistry -J-Djava.rmi.server.useCodebaseOnly=false
If you are using Eclipse ,Run the ServerSideProject and your ImplementationClass Instance gets bound to the URL specified.
Just print a line below the the binding method and see to it whether it is gets printed. If it gets printed successfully it means your server is working fine.

try to add /bin at the end of your VM Arg:
-Djava.rmi.server.codebase=file:${workspace_loc}/progInternet2008/bin
The file you will run are in this directory, so you need to include it in the path.

I upgraded from JDK1.6.0_33 to 1.7.0_45 and had the same problem. I found this document and resolved the problem by starting rmiregistry with:
rmiregistry -Djava.rmi.server.useCodebaseOnly=false
Refer below
http://docs.oracle.com/javase/7/docs/technotes/guides/rmi/enhancements-7.html

I had the same problem, to fix this ensure that your CLASSPATH is set to the path containing the server classes when running rmiregistry.
On a linux machine run the following commands.
export CLASSPATH="<server_class_path>"
Ensure the CLASSPATH has been set:
echo $CLASSPATH
Once the class path has been set, run rmiregistry
rmiregistry &

I spent a whole day uninstalling and reinstalling my JDK and changing the classpaths's and environment variables. But the culprit was that the command start rmigregistry didnt' start rmiregistry in a proper way. So, thanks for the comments on this page the solution was to unset the CLASSPATH temporarily. And that is done through the command set CLASSPATH=

How to deploy a report to Jasper Server

I tried to deploy a report to my jasper server. I followed this tutorial: http://randomallsorts.blogspot.de/2009/12/jasper-reports-how-to-deploy-report-to.html. But in the end of the day, when I tried to have a look at my report in the admin interface I just received a pretty long error which I don't understand.
The server has encountered an error. Please excuse the inconvenience.

Does anybody have a clue what could be wrong there ? I am sorry but I am really a ireport amateur.

First you should install the driver on your Jasper Server.
Go to the web interface with a user in the role ROLE_ADMINISTRATOR
On the tree view, you can create a folder to hold your datasource
In that folder, right click and add a data source
Give it a meaningful name for you and upload the com.mysql.jdbc.Driver (if not already present).
Note: if you did a manual WAR installation, you probably installed the driver already.
Download the driver here http://dev.mysql.com/downloads/connector/j/
Check the jdbc url. Should be something like jdbc:mysql://your_host/your_database
Small hack is to check your max allow packet setting in your MYSQL server and set it accordingly in your jdbc url. On MYSQL driver, check it using this command:
SHOW VARIABLES LIKE 'max_allowed_packet';
Then set the url to: jdbc:mysql://your_host/your_database?maxAllowedPacket=WHATEVER_SIZE_YOU_GOT
Check the username, password and timezone and test the connection.
Edit the report on the web interface and set the datasource as being this one.
When you upload a new report, either via web interface or iReport Designer, assign this data source.
Good luck, hope it solves your problem :)

try using this guide..
Seems like it cannot find the mysql driver to connect.

It seems the program doesn't recognize the codebase. In my case, all the files are local. Does anyone know what is the problem? thanks

Try explicitly specifying the name of the JAR file containing the com.ServerBootstrap.IServer class in your codebase, e.g.
-Djava.rmi.server.codebase=file:serverClasses/myjarfile.jar
The "Dynamic code downloading using JavaTM RMI (Using the java.rmi.server.codebase Property)" doc provides more information on the use of codebase and the options for its specification.

With a relative path specified for java.rmi.server.codebase, make sure that you are in the correct directory (the parent directory of "serverClasses") when starting the client. If that's hard to ensure, an absolute path for the codebase might be more reliable.
Also, remember that when running with the -jar option, the -classpath option is completely ignored. I don't think that's a problem here; the RMIClassLoader should still be able to work using the server's codebase setting. But if you are relying on the client having access to additional classes specified on the classpath, that won't work. You'll need to use the Class-path attribute in the main JAR file's manifest.

That's not a complete stacktrace, and I think you may have left out the part that shows the root cause of your problem.
If I recall correctly, ClassNotFoundException can sometimes be due to an exception thrown during static initialization of the class that is being loaded, or some class that it depends on. If this occurs, it will show up as a nested exception in the first stacktrace for the problem, at the next level of nesting. I recall (maybe incorrectly) that if your application repeats the attempted class load, the initialization exception is not in the resulting stacktrace.
EDIT: The complete stacktrace says that my theory is not correct.
