RMI and Netbeans

hello,
i have develop a simple application using RMI. It was running perfectly from command prompt.
Then i imported the project into netbeans 6.1. Then when i run it the server looks running normally but when a client try to connect to the server it given an error
java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: ........(No security manager: RMI class loader disabled)
Can someone help suggest a solution
Thanks

Hi!
Please tell me how could you get netbeans 6.1 to recognise an RMI project.
I have too, tried to import some old java files (two rmi interface files a server implementation and an applet) into netbeans 6.1. As far as i can tell it completely refuses to work with RMI, and i have not found ANY support on the internet so far, to how to do it, or any working rmi modules for netbeans 6.1 ...
Years old rmi developement, what worked nicely under windows 95 (good old days lol) does not wish to work for me now...
Should I return to use age old enviroments, or what?
I would deeply appreciate any help from You, or anyone able.
Thanks!

RMI and NetBeans again

Hi everybody,
I am doing one of my projects in university which involve remote method invocation.
I wrote a simple program using RMI and it works when I am running it from the console, but I am unable to run it in NetBeans 5.5.1
I found out that I need to add this text in build.xml file in my project
<target name="-post-compile">
<rmic base="${build.classes.dir}" includes="**/Remote*.class"/>
</target>but still I am receiving this notification
Trouble: java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:
java.net.ConnectException: Connection refused: connectMay be anybody know how to make it work properly?
Thanks!

So it works in the Console but not NetBeans?
Then your question belongs on a NetBeans specific forum and not a forum on Java programming in general.

RMI inside Netbeans and Logging of Network activities

I worte a program in jdk 1.6 that sets up an RMI and it worked fine. But when i took the same code into netbeans its showing an exception that the correct stub file is not available. Is there a way to create stubs from inside netbeans? in the rmic the file I gave was the implementation file but the netbeans package is asking for the stub file with the name client.logger, wee client is the package name.
Also please tell me if there is a way I can create a log of all the files transfered over LAN from the computer thats running the java program. It should log all incoming files and sender and files sent with the destination. I need these for a first year engineering project.
Thank you.

'Context is read-only' is not a Registry error
message. You are trying to bind to something else.
Show us some code.Well, I'm not doing a lot of binding, so I'm assuming it's this part:
               DDBServer stub = (DDBServer)UnicastRemoteObject.exportObject(this, 0);
               Registry registry = LocateRegistry.getRegistry();
               registry.rebind("DDBServer", stub);The error message is:
2007-04-18 14:06:40 NamingContextListener[Catalina/localhost/DDBServer]: Creation of the naming context failed: javax.naming.NamingException: Context is read only

Please help: RMI and Swing/AWT issue

Hi guys, I've been having a lot of trouble trying to get a GUI application to work with RMI. I'd appreciate any help. Here's the story:
I wrote a Java application and its GUI using Netbeans. In a nutshell, the application is about performing searches. I am now at the point where I need exterior programs to use my application's search capabilities, thus needing RMI. Such exterior programs are to call methods currently implemented in my application.
I implemented RMI, and got the client --> server communication working. However, the GUI just breaks. It starts outputting exceptions, gets delayed, doesn't update properly, some parts of it stop working.... basically hysterical behavior.
Now take a look at this line within my server class:
Naming.rebind("SearchProgram", mySearchProgram);
If I take it out, RMI obviously does not work... but the application and its GUI work flawlessly. If I put it in, the RMI calls work, but the GUI's above symptoms occur again. Among the symptoms are null pointer exceptions which all look similar, are related to "AWT-EventQueue-0", and keep ocurring. Here's just snippet of the errors outputted:

There are no complaints about anything within my code, it's all GUI related whenever I make a bind() or rebind() call.
Again, any help here would be great... cause this one's just beating me.
Thanks!

Maybe you want to change that worker thread to
not do RMI but anything else (dummy data) to see if it really is RMI, I doubt it, I think you are updating some structures that have to do with swing GUI and hence you will hang.
Just check this out.

Problem executing RMI Methods Netbeans

Hi everyone!
I�m using a system Servlet+applet that communicate by RMI with Netbeans.
The remote object, the stub and the binding are correctly created at the servlet. At the applet the reference to the remote object is ok too.
The problem appears when I invoke a method in the remote object from the applet.
The message the Java console throws:
RemoteException en soloEscribe()
java.security.AccessControlException: access denied (java.net.SocketPermission 192.168.1.100:1079 connect,resolve)
soloEscribe() is the method in the remote object.
I�m running everything locally, and I have granted allPermissions at the java.policy.
Hope someone can help!

to see whether it is able to look up the root context or not.
I saw that it is suceeded in finding the root context and print the message also , but again failed to rebind the object .thrwing following exception

Develop & deploy RMI in Netbeans 5.0

Hello,
I am a newbie to Java as well as RMI.
Does you develop RMI in Netbeans 5.0?
I would like to know if there are any existing built-in modules could help me in developing and deploying a RMI application in Netbeans 5.0. ( Or module update is appreciated )
The most important is [1] for generating the stub and skeleton file (i.e. executing rmic). Other features likes [2] providing sample interface files (extends java.rmi.Remote), interface implementaion files (extends java.rmi.server.RemoteServer or java.rmi.server.UnicastRemoteObject, or .... ), [3] I always develop server and client inside one project/package, in order to share the commonly-used server/client interface file. So within the same project, separately execute the application as Server-code or Client-code.
Or... you are welcome to share how you develop and deploy RMI inside Netbeans 5.0 is appreciated and also helpful to me ...
Thanks in advance !

I don't use netbeans, but it is a good idea to separate the projects. That way you can guarantee if the client works and if the server works, you can send the client to someone that it will work too. If you use them in the same project you can end up creating some dependencies between them.
I developed a RMI project on my college, we separated the whole thing in 3 differente self contained projects: a common, where the intefaces were declared, and were all the common libraries were stored, a server and a client, both using the library project as a jar.
As for netbeans, sorry if I can't help

What is the difference between RMI and JAX-RPC?

Dear All
First of all my understanding of RMI and JAX-RPC:
RMI is JAVA only version of RPC. It can't talk to any other language.
JAX-RPC is a part of JWSDP and if you implement your client and server with JAX-RPC, client written in any language can talk with JAX-RPC implementation.
What else makes them different and am I right with my understanding?
Finally, I would like to develop clients which will have a java class, say httpserver.java, which will act like a http server, listens to a http port. Now, Two such client will run in two different PC and I want to call a module from one client to another which should be accessible via my httpserver.java. For that which should be my choice RMI or JAX-RPC? Can I achive it with http get-post method, as I am expecting to read some value of variables from one client to the another.
Say class A has variable a, aa, aaa and clas B has variable b, bb, bbb. Now I want to read the value of b, bb, bbb from class A. How do I do that when class B is listening to a http port with my httpserver.java class.
Lastly, say B is listening to a http port and I want to send a file to B from A. How can I do that? Remember, B didn�t ask for that. How can A send a file to B when B is listening to a http port with my httpserver.java.

simply put, RMI allows you to (semi) transparently treat remote objects as if they were local, and your distributed application can be written (more or less) like a "normal" java app. Sockets just give you a "raw" connection to work with, and you get to build up your application from that.
I hope that helped

Connection to CRX via RMI and getting WeakReference value..... with an exception!

Hi there,
I have the following problem.
I opened a ticket in Day Care Support system, about CRX users/group membership that got lost while synchronization with our LDAP server.
Although when the user and the group had been created (and therefore taken from that same LDAP server), the membership was good.... but after some time the membership got lost......
So what i am trying to do now is a Java program that connects to CRX via RMI.
And gets the list of all the users from a group (aka membership).
The idea is to monitor the membership each seconds.
But when trying to get the property "rep:members" of the group, I have the following exception :
javax.jcr.ValueFormatException: Unknown value type 10
          at org.apache.jackrabbit.rmi.server.ServerObject.getRepositoryException(ServerObject.java:13 9)
          at org.apache.jackrabbit.rmi.server.ServerProperty.getValues(ServerProperty.java:71)
          at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
          at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:60)

          at java.lang.reflect.Method.invoke(Method.java:611)
          at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:322)"
I searched a little bit and found that "10" is the number for type WeakReference.
That's normal to me because memberships are stored in the group as a list reference to users linked to that group....
Anyways, what's not normal to me is that when the type is "10" the API does not let me get the Value (cf. ServerProperty.getValues() method)

Errors when using tomcat and netbeans combo.[Solved]

Hi I'm trying to set up a netbeans/tomcat7 development environment for servlet development.
I have tried this on 2 machines without any success.
The steps I have followed are as follows.
First I installed tomcat7 and netbeans from using pacman, then to be able to configure tomcat from netbeans I made the config files write permission 777, as it's just a development server security is not an issue.
From there I started up netbeans started a new project and set the server to tomcat and pointed the Catalina home dir to /usr/share/tomcat7.
When I try to run the example jsp project I get the following error:
description The server encountered an internal error () that prevented it from fulfilling this request.

I've spent the last couple of days trying to find any information on this but I cant find anything, so any advice would be much appreciated.

From the error, it appears that there is no JDK installed - only a JRE, could that be the case? If you do have a JDK installed, then Tomcat is not finding it.
I would also not run this on the openJDK, in case you are doing that. I would use the proprietary Oracle/Sun JDK. It's in the AUR, or simply download it from Oracle.
I was not even aware that netbeans and tomcat are available from pacman. I always "install" those myself manually (i.e. unpack them into a folder). They are simply Java apps that can be installed anywhere, as long as you point them to a valid JDK.

RMI and Swing Events

Hi,
I have a problem, integrating an application with RMI and a Client side with swing.
I have un RMI object that does something, and in any time I want to inform to the client side rmi... I did something like:
// This is the REmote implementation
public MyRemoteImpl extends Activatable implements MyRemote{
EventListenerList listeners;
// code for activation, etc.......
public void addListener(MyListener l){
    // add the listener in the list...
public void fireEvent(String msgEvent){
    // in each listener that is MyListener, .doEvent(String msg)
// Methods that calls fireEvent...
// Mylistener interface..
public MyListener implements EventListener{
public void doEvent(String msg);
// The swing client side.
public MyClient extends JPanel implements MyListener{
MyRemote rem=null;
// In the start of ui.. Ido:
rem.addListener(this);
public void doEvent(String msg){
    // Puts the message at one component....
}The problem is that when the doEvent of the Swing side is called, it is executing in the rmid... And the UI is not updated...
What I do wrong??
Thanks and Best Regards.

I wrote an application that does something similar, it receives some event and modifies a JTree accordingly. You should try using the java.awt.EventQueue.invokeLater(Runnable) method. Something like this:
public void doEvent(String msg) {
    // Determine what changes need to be made
    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            // Only the GUI component modification calls need to go here
}

RMI and native code

Hi
Can anybody send me a sample code(HelloWorld type)that is based on RMI and uses native code(eg. win32).
SANJAY

If you're trying to do anything with native code, then you should be familiar with JNI API, windows or not.
Check out the JNI tutorials on this site and i'm sure they'll provide you with JNI tutorials and samples.

Rmi and http

i know this might sound silly but i am new to rmi ( to java too )
i want to understand the difference between rmi and other protocols such as http,ftp and so.
now what i think i know - and sometimes think im not sure i know or
perhaps im sure i know nothing about - is that rmi is java specific and can only work with java while http is different if im not wrong.. and rmi does not require http r8?
so how can rmi work over http or ftp ..,( can it in the 1st place ?)

Which version of WLS you are using?
Applet should also need to satisfy the version requirements similar to
standalone java client. With WLS 5.1, it may work. But, it will not work
with 6.* servers.
Again, the JRE versions in the Netscape and IExplorer are different. So the
applet, working in IE may not work on Netscape. It is better to test a
sample application, than taking assumptions.

Basic doubts regarding ssl with tomcat 5.5 and netbeans 5.5 for WSDL?

I've just started my preparation of web services. I'm using JAX-WS to create my web services and client. I'm using Tomcat 5.5(not apache axis) to deploy my web services over https and i'm able to do that. I've configured my keystore and keystorepassword in tomcat's server.xml. After i've configured my web.xml to choose security type(choosen CLIENT-CERT). I'm able to run my web services over https. I'm using IDE as netbeans 5.5.
But to access this web service from core java client, i'm unable to do it. I've configure my jvmargs in the project-properties-run tab of netbeans and have given keystore,keystorepassword,keytrust,keytrustpassword. After all this i've also export it to the trustcacerts of tomcat. I want to run this using jax-ws. I've searched for many tutorials of this jax-ws , but all were in vain. Eventhough i've checked in java.dev.net site for tutorial but didn't find for my need. Everywhere they metioned on glassfish,wsit or some other technologies.
Right now i'm totally confused. I've read some little bit things of all these things and finally land it in the middle of the sea. Could anyone provide me the basic concepts or any url for this.
After all this i'm getting exception as : https hostname should be <localhost>. I'm totally confused what to do.
One more thing i just wanted to know that i'm diving into the jax-ws technology, is that right to buil an application on this or should i use JAX-RPC. Which one is better for accessing the url and should be secured from security propects. Also tell me is that possible to build web services on https with using tomcat5.5,jax-ws and netbeans 5.5 or should i need some technology for start up.

Any kind of help are welcome.

Does ATS load testing support Java RMI and T3 protocol?

Hi Experts,
Does ATS load testing support Java RMI and T3 protocol or EJB(J2EE)?
Thanks!

Joseph,
Oracle Application Testing Suite is mainly used for testing of applications from a end user perspective and offers an intuitive capture/replay for web, Siebel, EBS, JDE, Fusion apps or SOA based application through WebServices WSDL imports.
The scripting environment (Oracle OpenScript) does not support script creation by recording JAVA RBI or T3 protocol as we lack a recorder for it, but the scrips are created as pure JAVA code so you could use the JAVA language to write a small RMI cor T3 client for your testing.
We have customers that have used Application Testing Suite to test non-UI based testing, like: JMS, FTP, Tuxedo and others, but it require a bit of coding.
Please let me know if you would like to know more or discuss your options
regards
Mikael Fries
