Connect Exception trying to connect to rmi registry on a Linux box

I have prepared the Sun tutroial for RMI, implementing the remote method on a Linux box, and a client on the XP box. Try as I may though, the XP client always comes back with a Connect exception indicating it cannot connect to 127.0.0.1. I am though trying to connect to 192.168.0.4
The firewalls on both machines are open on port 1099, and if I connect from the client with telnet to port 1099 on the server something happens, (well the CMD box screen goes blank, and I get a cursor).
I'm struggling here, being both a Java RMI newbie, and likewise for Linux. I have seen suggestions that the hosts files may need modifying on both machines, but I am not sure what I might need to do.
Any guidance would be appreciated. Thanks in anticipation
P.S. I have posted this previously, but it seems to have expired. So, sorry for repitition, but I don't seem to be alone with this kind of problem.

I have made some progress if you can call it that. Doing what you (ejp) suggested with regards to the hostname, and the following helped.
Elsewhere on these forums I read of a problem where the rmiregistry was not being invoked by the JDK version. I forced this to happen by using an explicit path, then tested my client.
My client now starts, and does not crash with an exception immediately, instead it runs slowly, and then stops with a NoRouteToHostException, and now it is referncing the correct IP address. I am not sure how to resolve the cause of this exception. Again I have read elsewhere about IPTABLES being the cause of this exception, but I don't know what these are, or how to configure them.
Can someone guide me a bit more please.
Thanks

How to Connection CF10 to Apache on Separate Linux boxes

Is there documentation on this? We have CF10 installed on one Linux server and would like to connect it to Apache installed on a second Linux box.

Hi,
I have done this in Windows and Linux both for CF 9, but you can follow the same for ColdFusion 10. The place where we have to enter the IP address, put in the IP address of Remote server where you have installed ColdFusion 10.
In Web Server machine create the Identical directory as /opt/ColdFusion10/config/wsconfig and then place all the files,
Manual Connector for Apache: http://helpx.adobe.com/coldfusion/kb/coldfusion10-apache-manual-connector-configuration.ht ml
In ColdFusion server machine, you don't have to create this connector directory.
Please check this article, this is for CF 9.
http://helpx.adobe.com/coldfusion/kb/manually-configure-web-server-connector.html
Hope this helps.

RMI registry on multiple net interfaces

I'm interested in creating several RMI registry servers, each one listening in one different net interface of the same machine (two ethernet cards). Is there any way to do this without using custom RMI socket factories? From the documentation I have read, it looks like there's no possibility to choose a specific network interface. Instead, RMI registry chooses the one associated to localhost.
Thanks in advance.
Zealon

You could use
LocaeRegistry.createRegistry(port,csf,ssf) with an
RMIServerSocketFactory that binds the ServerSocket to
the appropriate network address, but you will then
discover that you can only have one Registry per JVM
because it has a fixed objectID, so don't bother.
But actually, why do you want to do this? Your stated
reason is not correct. By default any ServerSocket,
including those created by the Registry and RMI, is
bound to 'any', which means it should accept from all
network interfaces. Perhaps you have the classic
'hosts' hosts/DNS setup problem where your servers
embed 127.0.0.1 in the stub? Use
-Djava.rmi.server.hostname at the server JVM, or
better still fix your 'hosts' file or DNS setup.
EJPThanks for your reply. Maybe I didn't explain myself enough.
I'm working in medical electrocardiography, and have a PC with two net interfaces. The first one is bound to a LAN IP address that belongs to a medical network. Each one of the hosts in this medical network is an electrocardiography monitor, attached to a patient..
The second net interface is an external IP address (not LAN address).
I created a remote class called MonitorFactory, that should provide information about the electrocardiography monitors existing into the medical network. It works OK, and I cand bind MonitorFactory objects to a RMI registry with no problem at all.
There are some reasons I would like to use several RMI registries:
- First one, I need to control access from external network to my medical network. Medical patient data must be handled very carefully. I thought I could do so by enabling/disabling an RMI registry bound to the external IP address. This way, I could enable access to medical data from outside the medical network, by registering my MonitorFactory objects to this external RMI registry, but only when I decide to do that.
- Second one, I want an RMI registry always running bound to the medical LAN IP address, so I could use the applications that use MonitorFactory like a local application, not only like a remote one.
This scheme represents the system I have to build:
PC with two network interfaces
External PC <----------->|213.xxx.xxx.xxx 192.xxx.xxx.xxx|<----------> Medical network
MonitorFactory - Listens to medical data into 192.xxx.xxx.xxx network only. Bound to
external RMI registry when available and always bound to internal RMI registry.
External RMI registry - bound to 213.xxx.xxx.xxx. Enabled when I decide to do so.
Internal RMI registry - bound to 192.xxx.xxx.xxx. Always enabled.
If I create an RMI registry bound to "any" of the interfaces, I always risk my medical data to the Internet, because there is always a port open at 213.xxx.xxx.xxx accepting connections.
One possible solution could be using SSL sockets for RMI. This way, only allowed clients could connect to RMI registry. But what worries me most is the fact that a port could be open to the Internet - what about attacks to this open port? If those attacks could make RMI registry fall, medical data flow to another information systems could be interrupted, including medical alarms like critical patient status.
On the other way, I would like to maintain RMI default sockets for compatibility and future releases of my application.
Any suggestions?
Thanks in advance.

Cannot connect to the RMI registry.

SunMC 3.6.1 used to work fine, now get this error when running init.es_server start:

Where to look for the source of this trouble?Did anything change with your NIC/interface settings? Or VPN software installed? IPMP set up? I've seen things like this happen when an interface had been flagged as online... but has no IP info assigned. SunMC is going to try to grab ports on each interface... and if one doesn't have an IP assigned it will fail.

JNDI naming exception: Naming exception trying to connect to:help !!!!!!!!!

Hi,
Iam getting this exception and i have no clue what is this exception means.....and how to resolve this Naming Exceptions problem.
what iam doing is.....Iam trying to deploy a war file from my unix system to a win2000 machine(amasdqyt095).
This is where and how my script(myscript.sh) looks like:
java -classpath /xyz/bea/wlserver6.1/lib/weblogic.jar weblogic.deploy -port 7001 -host amasdqyt095 -component myWebApp:myserver update weblogic myWebApp /export/home/applications/xyz.war
i have created this script at: /xyz/bea/wlserver6.1/config/scripts/myscript.sh
then i did chmod +x myscript.sh
and the i did:
./myscript.sh
and then iam getting this exception:
JNDI naming exception: Naming exception trying to connect to: t3://amasdqyt095:7001 as: system: weblogic
please help ????
-sangita

I had the same problem because the weblogic.jar's version in the server was diferent from my machine (SP2 and SP4). I stops when I updated the server to SP4.
But now I'm having the same problem in another server, and the versions are ok. If anybody knows something else, please let me know.
I'm using Weblogic 6.1

Cant create JDBC Connections in RMI Server

I am having a pretty weird problem which I am struggling with for the last three days. In the main method of the Server object, following three things are supposed to happen:
1) Creation of a JDBC Connection
2) Creation of a Remote Object and then publishing the same to Registry.
3) Creation of another JDBC Connection (exactly same as in step1)
step 1 and 2 successfully executes and the third one always errors out. I just simply get a NullPointerException.
If I comment out step 2, step 3 executes successfully. Can someone please tell me the mystery? I need your response really urgently so please help me.
TIA

In reply to reply #4:
You can also quote the other part of my reply when it comes to snippets. There are so many pieces of code missing from your snippet that I simply cannot guess what is wrong. (Please do not put your entire class structures here.)
We get connections in many different classes at many different times. It is after all an application that does user work and the user work involves database accesses. Some of those accesses are before RMI (to establish repositories, etc). Most are after.
This URL (jdbc:oracle:thin:@wonder.cisco.com:1521:ODSDEV) appears to use a network connection (yes?). Is the 1521 a port? Are you trying to reuse this port? (the first conn uses the same URL). What port does RMI use?
There is nothing in your snippet that stands out obviously as "this is wrong".
RMI uses networking. JDBC uses networking.
Try substituting some other networking code in place of the RMI code and see if you still get a null trying the second connection. As you say, if you leave out the RMI code the second get.conn works.
Try leaving out the first get.conn. Do the RMI and second get.conn.
Try this and try that and try some more. I once had this problem with a network printer that would not print. The code was fine. The URL was fine. The response from the network and printer were both fine. The damn thing just wasn't printing. Turns out there was this bit, yes a single bit, in one word of a property called the "start print bit". If this bit wasn't on, nothing happened. I tried every combination until I finally found it.
I wish you the best.

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?

Connect caught listing registry?

I ctrl-c'd my running RMI server and, as expected, cannot create a new registry on this port.
However, I created a small test app to attempt to 're-attach' to the registry:
try {
/* does one already exist? */
serverRegistry = LocateRegistry.getRegistry("localhost");
System.out.println ("\n\nReturn from locateReg = " + serverRegistry + " \n\n");
try {
/* show names bound in registry */
serverRegistry.list();
LocateRegistry succeeds in returning a Registry object.
However, serverRegistry.list() throws the following exception:
Exception java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:
java.net.ConnectException: Connection refused: connect caught listing registry
I've probably oversimplified what needs to be done to regain access to the server, but does anyone know what's going on here?

LocateRegistry.getRegistry() merely gives you a client stub to the registry. Because the registry uses a well-known remote ID, this call will always succeed and by itself does not guarantee that the registry is up and running. You need to execute an actual registry API call to make sure [and list() is a good choice, for example].
Is your registry embedded into the server VM or running in a separate process [rmiregistry.exe]?

Unable to connect to Services Registry(error) while connecting from NWDS

Hi SDN friends,
I am trying to do WSDL import from NWDS (Developer Studio SAP NetWeaver 7.1 Composition Environment SP03 PAT0000 Build id: 200710302120 ) and i am getting following error
"Unable to connect to Services Registry"
Below are the service regsitry details i am passing

Hi,
You wrote that you connect to the SAP uddi:
Service Registry (UDDI Service)
Server Name:sr.esworkplace.sap.com
Server Port:sr.esworkplace.sap.com
Server Port:50000
Server HTTPS Port:50043
Inquiry Path:uddi/api/inquiry
Publish Path:uddi/api/publish
Security Path:uddi/api/security
sr.esworkplace.sap.com is not on your home pc. Its a SAP public uddi.
If you want to connect to your own pc than your configuration would be sompething like this:
Server Name:localhost
Server Port:50000
Server HTTPS Port:50043
Inquiry Path:uddi/api/inquiry
Publish Path:uddi/api/publish
Security Path:uddi/api/security
And you shouldn't use this login data
login/pwd: sruser
password: eswork123

This OC4J is configured to make JMX connections via RMIS...error!

Hello,
I have just installed OBIEE and when I try to log into Oracle Enterprise Manager 10g and got the following error:
This OC4J is configured to make JMX connections via RMIS and fall back to RMI if the RMIS port is not configured. The RMIS connection on the OC4J local instance is configured but a connection could not be established. The JMX protocol is specified by the oracle.oc4j.jmx.internal.connection.protocol property in opmn.xml
I have tried to reinstall OBIEE a couple of times but still get this error. Please let me know what I need to do to get this up and running.
Thanks!
Linda

This may be because of the host name. You might have any special characters in host name, remove any under scores in host name, restart computer and check it.
if not let me know what URL you are using.

Event 31901 – The registry probe could not connect to the registry of the computer name

Hi, I have been doing a weekly SQL query to try and find any high number of events I get in my SCOM environment.
One of the events I have stumbled across is 31901 (“The registry probe could not connect to the registry of the computer <name>”) which comes from the “Collect Registry Probe Module Events”
I have read a couple of previous suggestions on the forum and upon checking I found two different scenarios. For a couple of servers I checked the health and it looked like they had RPC issues. A restart got rid of these problems.
However the ones left seem to have something in common. They relate to hosts referring to SQL “instances/clusters”. So the “logging computer” is the host and the probe cannot to the registry of the “virtual computer”. In other words the computers that can’t
be connected to are all agentless and show as managed by the logging computer under “Agentless Managed”
If I log onto the host with my SCOM action account and run something like “reg query” against the virtual “instance” I get “ERROR: The network path was not found”. I can ping the instance fine though. I don’t really understand how these instances work but
I presume they don’t have services or a registry as such. Therefore is this normal or is there any way I can get rid of the events? I don’t really want to get rid of the rule itself as it did help me find a couple of RPC issues. I could override for that host
if this is “normal” and how it should work.

For issue "31901", you can check below link

Error While Connecting through RMI

Hi,
I am getting the following error when connecting to the server through RMI.This problem is occurring only in Linux and when connecting remotely.In windows we are able to succeed and if both server and client in the same machine able to connect.The problem persists when connecting to the server remotely in Linux.
Caused by: java.rmi.NoSuchObjectException: no such object in table
at sun.rmi.transport.StreamRemoteCall.exceptionReceiv edFromServer(StreamRemoteCall.java:255)
at sun.rmi.transport.StreamRemoteCall.executeCall(Str eamRemoteCall.java:233)

Can anybody please help me regarding this.
Thanks in advance,
Thanks & Regards,
Jyothi.

The remote object has been unexported, probably via DGC action. The solution is to hold a static reference to it in the server JVM.

RMI registry reset

Hi there,
I'm writing a RMI application where I need to clean up the RMI registry as soon as the ip address of the server machine changes.
Let's say that I want to make an object (class Obj) accessible from a RMI client through the following code:
Obj obj = new Obj();
UnicastRemoteObject.exportObject(obj,RMIPort); //export the new object
registry = LocateRegistry.createRegistry(RMIPort); //Create a new registry
registry.rebind("myObject", obj); //Bind the object to the registryOnce I detect an ip change I need to clean up the register and I need to publish a new Obj object on it. The new object has to accessible from a RMI client instead of the previous. I tried something like:
UnicastRemoteObject.unexportObject(obj,RMIPort); //unexport the old object
Obj obj2 = new Obj(); //Create a new object
UnicastRemoteObject.exportObject(obj2,RMIPort); //export the new object
registry = LocateRegistry.getRegistry(RMI_PORT);
registry.rebind("myObject", obj2); //Bind the new object to the registry with the same name "myObject"But when the last line of code is executed, an exception "java.rmi.UnmarshalException: Error Unmarshaling return header" is thrown.
Do you guys have any suggestions?

This is the complete stack trace:
java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is:

RMI registry inside tomcat

Hello,
I'm wondering if any of you have previous experiences in the following situation.
I have a linux server with tomcat 5.0.28 that is supposed to act as an RMI end point for clients connecting with the aforementioned RMI to do some persisting stuff. Now I figured that the easiest way is to create a servlet that creates the RMI registry and binds my server objects (so that's in the servlet's init(), with 1 load-on-startup, the servlet doesn't do anything else, at least yet).
Now problems arise: my linux server is logging "context is read-only" when trying to bind the objects to RMI. Testing on my windows laptop doesn't show the same error for some reason (although it doesn't work properly either). This is apparently normal, as the contexts are supposed to be read-only.
Thing is, I wouldn't want to run a separate rmiregistry on the server, if possible to do it with a simple servlet. But is this the easiest way?
Thank you in advance,
yours truly, in sickness and in health,
Jussi

'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
