Java -Djava.rmi.server.codebase=file:///.....

Cross posted in the hope that someone using it knows how....
I am using the following command:
java -Djava.rmi.server.codebase=file:///home/ben/fyp/build/ -Djava.security.policy=security.policy -cp ./lib/bcprov-jdk15-130.jar:./props:./build com.bensmyth.fyp.example.IssuerServer
Can I specify -Djava.rmi.server.codebase=file:///home/ben/fyp/build/ without giving the whole path? Can I say ./build?

I've come back to this issue again (since I am moving code around to different systems again). Using linux I can use -Djava.rmi.server.codebase=file://$PWD/build/
Presumably there is a similar command in WIndows.

Java.rmi.server.codebase=file:(?????); at client side: classnotfounexceptio

I'm trying to run an RMI application (under Windows XP, one machine for client and server) like this:
at server side:
java -Djava.rmi.server.codebase=file://\..\..\..\j\ -Djava.security.policy=file:.\polityka.txt sss
- and it works fine, but at client side:
java -Djava.security.policy=file:.\polityka.txt -Djava.rmi.server.codebase=file://\..\..\..\j\ kkk
results in:

Spaces in -Djava.rmi.server.codebase path

hello,
how must i format the string containing the codebase for a rmi server if the path to the codebase contains spaces?
-Djava.rmi.server.codebase=file:c:/path/ and -Djava.rmi.server.codebase=file:/path/ works, but
-Djava.rmi.server.codebase=file:c:/path with spaces/ doesnt work
i have tried to put the string in quotes and to replace the spaces with %20 (url encoded)
but nothing does work.
how must i format the string?
cu,
elmar

I guess you are using a batch file to start your RMI application.
Spaces in URLs must be encoded with %20, that is correct.
The problem is: the command line interpreter on Windows interprets % as a special character and will replace it.
What worked for me (Windows Vista):
java -Djava.rmi.server.codebase="file:/C:/Users/FirstName%%20LastName/RMI/" App
So encode each white space with %%20.
You can very easily check by inserting the following code at the start of your RMI application. These lets you see how the codebase is set.
System.out.println(" Codebase: " + System.getProperty("java.rmi.server.codebase"));

Rmiregistry �J-Djava.rmi.server.codebase=URL

Hi all,
When starting the rmiregistry, I do the following:
rmiregistry �J-Djava.rmi.server.codebase=URL
Eager to understand what is going on, I read that this means the following:
RMIClassLoader:
For stubs and skeletons of remote objects created in the local virtual machine, the URL specified by the local java.rmi.server.codebase property is used.
I thought "hey why not do the same for the server" and tried:
java -Djava.rmi.server.codebase=URL Server
getting me a StubNotFoundException. Can anybody tell me what I am doing wrong? The Server works when the Stub is in the local classpath but refuses to load it via the http Server. Am I at least theoretically right or is there a fundamental misconception in what I am trying?
Thanks,
Ralf

RMI uses annotations to record codebase information. In addition to recording the class despriptions also records info about the location from which it loaded the classes bytecode. If you are trying to specify the codebase on the server and removing the stubs from the servers classpath the bytecode will never actually get loaded.

-Djava.rmi.server.codebase Question.

When I study the meaning of codebase in
http://java.sun.com/j2se/1.3/docs/guide/rmi/codebase.html
, I am still confuse what is different between codebase
settings in Remote Object side and RMI Client side.
The command options -Djava.rmi.server.codebase=
http://myHost/myDir and -Djava.rmi.server.codebase=
http://wwwserver/mydirectory ( in Figure3 and Figure4 of
http://java.sun.com/j2se/1.3/docs/guide/rmi/codebase.html
) are set in which side ??
The option in Remote Object side seems no any work.
Who can explain its meaning ??
Thank you in advance... Alan.

Hi,
For the dynamic class loading to work, you should give
-Djava.rmi.server.codebase=http://some-server/
you can see that it supports http protocol.. So there should be one web server running on the server side so that client can call it by name or by IP address.. Then try running the program again. now it will work..
actually you should give this option on client side as it is the client who needs this property.. so in order to download classes the server machine should be addresable to the client in any method. if it is a LAN, try giving '\\computer-name' in the value of the property.. I haven't tried this, but I think you dont need a http server this time.. I am not sure abt this,,. check it out..

Option '-Djava.rmi.server.hostname' unnecessary?

In this tutorial:
http://java.sun.com/docs/books/tutorial/rmi/running.html
you start the rmi server with:
java -Djava.rmi.server.codebase=file:/c:\home\ann\public_html\classes/
-Djava.rmi.server.hostname=zaphod.east.sun.com
-Djava.security.policy=java.policy
engine.ComputeEngine
but in this tutorial:
http://java.sun.com/j2se/1.4.2/docs/guide/rmi/getstart.doc.html#5321
you start it without the Djava.rmi.server.hostname option:
java -Djava.rmi.server.codebase=http://myhost/~myusrname/myclasses/ -Djava.security.policy=$HOME/mysrc/policy examples.hello.HelloImpl
I have also tried to omit the hostname option from the first tutorial and it works fine..
Why is it not necessary to specify the Djava.rmi.server.hostname option to make the examples work?
What is the function of this option?

It's only necessary if you have a fouled-up DNS which doesn't give the right hostname by default.
And if Sun had understood the TCP weak-end model better than they did in 1996 it wouldn't be necessary at all.

RMI Server Codebase Permission Denied

I'm having a problem trying to get my application running in a test environment. I currently have this same application up and running in an almost identical location without any issues, and I'm at a loss to understand what the problem is.

Out of growing desperation (and since it's a test VM in virtual box so I'm not really protecting anything) I've already granted full permissions to everyone for these these files in the filesystem itself - chmod -R 775 - and I've made sure that common.jar is accessible. I also double-checked the Security Policy, Djava.security.policy, and that's just a straight all permission to everything (again, I'm not protecting anything on this test).

What's really driving me nuts is that this exact same code is already running and working on another machine. There are no environment variables that I'm missing, and I don't see how those would relate to this problem even if I did. The directories are identical, and I've verified the location that's listed as the cause (/usr/local/app/app/common/lib/) exists and is accessible. I keep coming back to the file permissions and the security policy and I'm sure I could be missing something obvious, but I am not seeing it at all. Can anyone give me some advice on this?
I'm running a VM in VirtualBox 4.1.4, running CentOS 5.7 32-bit. Java is JDK 1.6.0, just the basic yum install package.

This is a .policy file problem, not a filesystem permissions problem. Run it with -Djava.security.debug=access,failure to see exactly what is going on. Basically your .policy file either doesn't grant the required FilePermission or isn't being loaded.
NB a codebase of a local JAR file isn't going to work unless all the clients are in the same host.

Java.rmi.server.codebase in JSP

Hi,
i have a system made from an RMI client and an RMI server. The users access the system through a JSP page, which creates an instance of the RMI client. In order for the system to work, i need to specify the java.rmi.server.codebase property.
For testing purposes the client has a main(..) method. If i run just the client the server and specify java.rmi.server.codebase, everything works.
If i don't specify it i get a java.rmi.UnmarshalException, with the nested exception of ClassNotFound. The same exception i get trying to access the jsp page. So, i guess, it's due to the lack of the property.
I tried setting the property in the jsp page, but it doesn't work.
Thank you.
P.S. : maybe this is relevant: my jsp server is tomcat 6.0.

it refers to where are your stubs and skeletons
you can set it to point to the jar files or to the directory that contains them
hope htis helps
regards
marco

How to interpret rmi log msgs when setting -Djava.rmi.server.logCalls=true

i have set this property: -Djava.rmi.server.logCalls=true
now i am getting the following rmi log msgs on the console:

can some one pls tell me know to interpret the messages, what does the number 4853 in TCP Connection(4853) mean ? thanks a lot

Basically it is:
date:subsystem:threadid:[remote object[object-id]:method]The 4853 is part of the thread-id and it is something like an instance number of the thread class.

Is it a must to set java.rmi.server.codebase property?

As to my understanding, only when JVM cannot find the necessary class from the local CLASSPATH will it tries to download the classes from the codebase right? so if the class exists in the local machine, actually it is unnecessary to set this property? Urgent, help!!!!!

Correct.

Rmi.server.codebase property

Hi i am new ,
I've writting a small RMI-application using Apache webserver lo load classes,that will be needed by client.
the question:I will instead of webserver(http or ftp) a file protocol and as codebase a networkdrive,that be of course from client accessible
what muss exactly written in the property?

RMI Server

Alright guys I am trying to get a Simple RMI example running. I can run the registtry from the command prompt but cannot get the server started.
My command to run the server and the error are as follows
C:\Documents and Settings\John\jbproject\simple-rmi\classes>java -Djava.rmi.server.codebase=file:c:\Documents and Settings\John\jbproject\simple-rmi\classes\ -D

mpleRMI.policy simple-rmi.SimpleRMIServer
Exception in thread "main" java.lang.NoClassDefFoundError
Any ideas, I am going crazy I have cjecked the paths individually using another command prompt and it is fine. Advice???

Please check that your program can find all necessary classes. It looks like your application is missing some classes. Check the "visibility" of your classes, their names etc. (public MyClass ..)
As the error says no class found... if you are using "package"-keyword please check that you are importing right classes from packages.(import packagename.YourClass...)
