RMI Server as a service

I've have a very simple RMI Server that handles authentication for a Java Web Start app. This server app has been running as a standard console app and now I want to run it as a service on a Windows Server 2003 box.
I've tried Java Service Wrapper (http://wrapper.tanukisoftware.org/) and the built in tool in Windows for creating services (sc.exe) but no avail.
I'm becoming desperate and have begun peeking at full fledged application server such as JBoss and Suns application server. Those guys should be a total overkill since my tiny RMI server is as far away from J2EE as you can come.
Could someone provide me with some hints on this one? All I want is to have my server app run as a service, how hard should this be?

Dear Sacke,
Did you find anything on this front? I also need develop an RMI server and deploy it as Service (on Windows) and Daemon on Java. And I particularly dont want to use the Java Service Wrapper as it is not a pure java solution. Please let me know if you found anything on this?
Thanks,
Mehul

How to Convert an RMI Server into WINNT service

I have an RMI Server, that looks like the following
SimpleRMIServer.java
import java.io.*;
import java.rmi.*;
import java.rmi.server.*;
import java.rmi.registry.*;
import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;
public class SimpleRMIServer
public static void main(String[] argv) {
System.setSecurityManager(new RMISecurityManager());
try {
LocateRegistry.createRegistry(1099);
SimpleRMIImpl implementation = new SimpleRMIImpl("SimpleRMIImpl instance");
// SimpleRMIImpl implementation = new SimpleRMIImpl("SimpleRMIImpl instance");
System.out.println("SimpleRMIImpl ready");
catch (Exception e) {
System.out.println("Exception occurred: " + e);
the SimpleRMIImpl.java also is available. (SimpleRMIImpl.class)
now the problem is how to convert this Server to a service.

using the jntsvc.exe tool, that code have been converted to an executable, then installed as a service.
I've tried to embed the RMIServer code in the constructor for this service, but it didn't work
Hope you have a clear understanding of what I'm saying
any help, highly appreciated
thanx in advance

Java Web Services accessing rmi server

Hi,
I want to access the rmi server from a java web services.My java web services is running under Sun application server9.The rmi server is not using any application server.Please help me to sort out the problem.
Bye
Binay

What's the problem exactly? I assume you understand that the RMI server has to run like any RMI server, it has to bind itself into a Registry; the Web server acts as an RMI client so it has to look up the Registry to get a remote reference so it can call the required remote methods.

How to Start Java RMI Server Application as Windows NT Service

Hi!!,
I have problem regarding the Installation of Java Application as NT Service this Java app in turn will start RMI Registry using LocateRegistry.createRegistry() at some specific port number. The Service is created successfully but i have problem regarding the Accessing of this Remote Object using Lookup() .(ie) I am able to get the RMI Registry Obj Refererce of the Java Rmi Application but couldn't able to Lookup for the Object registered to this Rmi Registry.I am not able to proceed after getting the Rmi Registry reference.

Attempting to use SSL over RMI from a web application to a RMI server

I don't see anything that indicates SSL was directly a factor in the
failure.
From the exception stack it looks like a more basic connectivity issue,
maybe the URL for the
RMI server is incorrect for some reason or the server was down.
It looks like you are doing something like this:
SSL client -> WLS server with servletA, servletA RMI client
(com.hyperion.css) -> RMI server
The connection failure appears to be the connection from servletA RMI client
to the RMI server.
Is that a correct picture?

Crazy Exception blocked my RMI server

Hi all one crazy exception is thrown when I try to start the server. Plz reply me the the possible cause and solution.
thanks in advance
The exception is :
Error starting service
java.rmi.server.ExportException: Listen failed on port: 0; nested exception is:
java.net.SocketException: JVM_Bind (code=10055)

You cant listen / bind on port 0. Try a different port number greater than 1024. That should work out.

How to get the IP address of RMI server???

Hi:
Is there a way to know the IP address of RMI server before client and server connect?
I am assuming that client didn't know the IP address of the server.
Because I know that client must hold a server reference so that client can connect to server.
But I want my client program to find out server IP address before they connect and use this finding to connect to server.
Is it possible?
Thanks!

So you KNOW that the client MUST know where the server is yet you want the client to find out where the server is?
Simple answer: forget it.
If you don't know where to connect to how are you ever going to connect to it?
And if you do know you don't have to go looking it up...
You can probably do something with JNDI, but then you're only putting off the inevitable as now you need to both know how to contact the JNDI server AND the JNDI server needs to know where the the RMI registry for the service you want to connect to is.

Hi Pyung,
How about trying this instead:
InitialContext ctx = new InitialContext();
MediatorInterface mediator = (MediatorInterface) ctx.lookup("TestMediator");
This assumes your startup class binds the Mediator to the JNDI name "TestMediator".

RMI server appears to deadlock but is fine after...

I have a RMI server that is providing services to clients on my network.
When I run tests from the clients (an app that constatnly makes demanding method calls to the RMI server) everything runs fine.
I have one Windows 2000 client and one Slackware Linux 10.1 client, everyone has the same version JVM. They both run the "stress test" at the same time. The Server is a Windows XP MCE on a dual core Processor, the OS has been configured to run both processors.
Both clients run for hours (all day) and so does the server without problem. Except sometimes I come back and it looks as though my clients are expererinceing some type of deadlock and when I check the server it is sitting there not doing anything as if everything is deadlocked.
Now the magic, at the server console I smack a few keys on the keyborad and everything jumps back into business humming along just fine.
What the heck? I have had this happen more than once. My apps have no input facilities whatsoever except CTRL+C which I use to kill them when I'm done with my "stress test".
I have noticed Windows clients can kinda drag everyone else down because of the way it schedules threads.
Any ideas?
Sean

Sometimes thread prioroties can be used effectivly on
Windows if you are having problems with your WINDOWS
machines handling the threads "properly". But not
much use really.
For testing? OK.
I have been developing and testing parallel threaded
applcations and it would not be possible without a
dual-processor machine (properly configured).
Number of processors is irrelevant. Why do you think this makes any difference at all?
You cannot test threaded applications on a single
processor. Single processor runs ONE thread at a
time. Dual-Core or dual processors can run THREADS
in parallel. I've seen it work, beautifully. your
threaded app may run fine on one processor BUT if you
run it on a dual machine it may break. In computer
science parallel computing has been around for a long
time but the majority of people (programmers) have no
idea about it whatsoever and there is a lot of
misconceptions.
I happen to have a Masters in distributed computing. I quite enjoy it. And I still insist that a dual core system is not going to do anything to your threads that a single core system won't do to your threads.
I challenge you to write a program that can tell the number of processors present, without checking the system property. If the OS is properly written and the chipset is working as it should, your program can not tell.
One thing I see repeated is that dual-core machines
have liitle impact on performance because most
applications have only a single thread. Horse
feathers!!! Windows and any other OS is going to run
applications in parallel!! I have noticed a nice
improvemnet in basic operations on a dual-core
(properly configured).
applications don't run in parallel, threads do. adding a 2nd core may make your computer more responsive if the OS preemptive scheduler is poorly written. Otherwise its no different than adding a faster CPU.
This is a wonderful subject (Parallel Computing, the
new PC)and I'm hooked (bad) mainly because this area
is almost unexplored by the masses and there is a lot
of work (read innovation) that needs done in the next
decade on the software end. If you like serious PC
check out Solaris (awsome).I love it. I was working on parallel code in Linux several years back while in school. Its not unexplored really. Search for distributed computing and you will find lots of info. The thing that is new is the attempt to take advantage automagically of multi cpu by programs that were not written to take advantage.
>
P.S. My dual-core 1gig SATA (XPS) Dell machine just
caught up with my PIII single CPU 512mb SCSI U-160
(500sc)machine in total throughput. seat-of-pants
All this swapping has to go.

DataVirtueMy last dual cpu machine was a abit BP6 dual celeron. Its a nice novelty, but buying dual/cpu dual core makes no sense unless the fastest single CPU is not fast enough or the price is right. Dual-cores has come about because the CPU folks are having difficulty making the single CPUs faster. Its a cop-out really. Instead of advancing technology, they add a 2nd CPU and try to act like they did something.
Anyone that chooses a dual-core CPU over a twice as fast single core CPU either does not understand distributed computing, or enjoys the novelty.

Connect Via RMI To A Remote Service?

Has anyone connected, via RMI, to a remote service within an application module? Currently this seems to wreak havoc upon all future and current ORMI communication to and from the application server in which a model is deployed (or at least within a container). Does anyone have any idea on how to do this correctly?

Has anyone connected, via RMI, to a remote service within an application module? Currently this seems to wreak havoc upon all future and current ORMI communication to and from the application server in which a model is deployed (or at least within a container). Does anyone have any idea on how to do this correctly?

How to set the granted permission in RMI SERVER site

Hi everyone,
I have developin some simple RMi program but the error message is keep on prompting out and I cant really test out what is the result. I understand I got to GRANT the permission for the RMI but I I dun really know where should I start first. I know there are code that can be implement in the sErver site, just hope some one can guide me out.
Thank lot...
here is the code for server:
import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;
public class myRMIServer
public static void main(String[] argv)
System.setSecurityManager(new RMISecurityManager());
try
myRMIImpl implementation = new myRMIImpl("myRMIImplInstance");
catch (Exception e)
System.out.println("Exception occurred: " + e);
Where should i code the getProperties and setProperties code...

so, what u mean is the problem occur doesnt related to coding part ?? do you think it is because I did not start the rmiRegistry, but somehow when i started the rmiRegistry, the console window is blank an it is nothing in the window. pls pls help me to solve this problem... sound easy initially but end up it is not...
by the way, here is the code
Interface
public interface myRMIInterface extends java.rmi.Remote
public java.util.Date getDate() throws java.rmi.RemoteException;

import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;

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();
server
import java.rmi.*;
import java.rmi.Naming;
import java.rmi.RMISecurityManager;
import java.rmi.server.UnicastRemoteObject;
import java.rmi.registry.LocateRegistry;
import java.util.Properties;
public class myRMIServer
public static void main(String[] argv)
//System.setProperty("java.security.policy","C:\\workspace\\MyRMI\\java.policy");
//System.getProperty("java.security.policy","C:\\workspace\\MyRMI\\java.policy");
     //myRMIServer m = System.getProperties();
     //m.setProperty("java.security.policy","C:\\workspace\\MyRMI\\java.policy");
     //System.setSecurityManager(new RMISecurityManager());
//Properties p = System.getProperties();
//p.setProperty("java.security.policy","C:\\workspace\\MyRMI\\java.policy");
try
myRMIImpl implementation = new myRMIImpl("myRMIImplInstance");
Properties p = System.getProperties();
     System.setProperty("java.security.policy","C:\\workspace\\MyRMI\\java.policy.txt");
     System.setProperty("java.rmi.server.codebase","file:///P:\\Projects\\RMIServer\\bin");
     if (System.getSecurityManager() == null) {
     System.setSecurityManager(new RMISecurityManager());
     System.out.println("Security manager registered");
     //System.out.println("Service registered");
catch (Exception e)
System.out.println("Exception occurred: " + e);
here is the code, to run, I got a client one as well, but is just for displat purpose..
thank you, guys....really appreciate ur help

J2EE problem while accessing RMI server

Hi,
I have a J2EE application in Oracle 9iAS server, I have created an application which access a RMI Server runs in a different PC, it works fine in my /dev site, I moved the same files to /test site (Same machine but different context), which also access the same RMI Server, now my application throws the following error in /test site where as it is working perfectly in /dev site.
If you have any idea on this please let me know. Thanks in advance.
Regards,
Venkat

Looks like ClassLoader tries to load different class. Check your classpath, check where are classes com/sgsap/feed/server/IFeed and if there are more than one such class, check why if your app is in /dev it is loading different class than when it is in /test.
Other solution could be that something gone wrong while compilation. Are you sure you was not recompiling any code between testing it on /dev and on /test?
I do not know, I am just trying to give some clues.

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.
My application is an RMI server-client setup. At the moment, I'm having trouble with solely the server portion, as I'm unable to get it to access the codebase. I start the application with the following runServer.sh file (located in /usr/local/app/app, so the $ROOT_DIR=pwd is correct):
Line: -----
#!/bin/bash
ROOT_DIR=`pwd`
JAVA_HOME=/usr/java/latest
CLASSPATH=''

#:: to the location where you have distribution URL.

After running this, it fails at that last line, $JAVA_HOME/bin/java etc. Near as I can see from the error is that it cannot access the -Djava.rmi.server.codebase.

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).
Line: -----
grant {
permission java.security.AllPermission;

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.
