OC4j connection refused

Hi!
I have a problim with new application server connection from JDeveloper. Version 9.0.2.0.0.
I have installed Developer Suite. Started OC4j instance.
Checked it. Everything is running. I can see start page.
But cannot create connection to that local instance.
ran java -jaroc4j.jar -install and changed admin password.
But it doesn't help at all.
Whats up?

Addtitional info.
Seems like it's trying lookup JNDI.
I thought it's configured to use local XML file as storage.
How i can check it?

Jdeveloper 11g TP4: Connection refused error for Embedded Oc4j

Hi,
I am getting following error whenever trying to deploy any application in embedded oc4j or whenever try to connect with embedded server on Resource palette.
Error while getting remote MBeanServer for url: ormi://127.0.0.1:23891/default:
Error reading application-client descriptor: Error communicating with server: Connection refused: connect; nested exception is:
     javax.naming.CommunicationException: Connection refused: connect [Root exception is java.net.ConnectException
I am using Jdeveloper 11g TP 4 on windows XP.
I have checked other links too related to above error and have checked following:
Proper host name entry in host file
No spaces in Jdveleoper installed directory name
Proxy setting in Jdeveloper: excluded localhost and ip address
Will be very thankful if anyone can help me to resolve this issue.
Thanks in advance

Don't spend to much time on this. JDev 11g is production and there will be no OC4J 11g!

Calling a WebServices From Java Stored Proc fails with Connection refused

I have followed the example in Note:220662.1 on Metalink step by step.
I am using two windows machines (2000 SP4). I have Oracle 9.2.0.5 EE on one of them and OC4J 9.0.4 standalone on the other(running on JVM 1.4.2_05-b04). The 2 servers "see" each other over the network.
I can execute the stub from the database machine:

What am I doing wrong? The embedded OC4J library is added to the project. I've tried to use the javac compiler. It looks like the OC4J instance cannot make a connection to the db.
Thanks,

I've added the connection to the web.xml, but still get the same error.
When I go to embedded OC4J preferences and change the JNDI-names of the datasources (global and current-workspace) to the same name (this was default), i get this error message:

Bi Server Connection Refused

JNDI Connection refused error

HI
I am new to Java so please excuse my stupid questions and general lack of ignorance. I am trying to connect to an Oracle database using JNDI to retrieve a Datasource using a 'data-source.xml' file but I get a 'Connection refused' error I am at a total loss at what this can be, I just have a simple Java Class which gets an InitialContext then does a lookup from here but this is were it fails.
Could anybody give me any idea as to where to look. Could it be a problem with the JNDI server itself?. I'm using JDeveloper 10.1.3 and am just trying to run it in the embedded server.
Sorry for the general rambling nature of this post and please ask me to provide any extra information required.
Any help would be much appreciated as I'm going nowhere with this at the moment and very frustrated as have searched everywhere with no results.
Thanks
Andy

Hi
Thanks for the reply. I have checked my data-sources.xml and this all seems fine. I can even connect to the DB using DriverManager rather than the JNDI method. One thing that confuses me is which data-sources.xml it is using as there appear to be many. In JDeveloper you can specify the data sources in 'embeeded oc4j preferences' plus create your own under meta-inf. Which is being used when run in embedded, maybe thats obvious the first one?
thanks once again

Admin.jar connection refused

I have an EAR file built in JBuilder 7 which I'm trying to deploy to my demonstration Application Server using the JBuilder 7 plug-in for OC4J. Whenever I try to deploy, I get
...\jdk1.3.1\bin\java -jar "...\ora90\j2ee\home\admin.jar" ormi://localhost:23791 admin narf -deploy -file "C:/devt/010Plus/010Plus.ear" -deploymentName 010Plus
Error!!!: Error: javax.naming.NamingException: Lookup error: java.net.ConnectException: Connection refused: connect; nested exception is:

Now, doing anything "admin.jar" from the command line gives me the same result -

Error: javax.naming.NamingException: Lookup error: java.net.ConnectException: Connection refused: connect; nested exception is:

I've been through the 9ias installation guide and the JBuilder plug-in documentation with a pretty fine-toothed comb, but still there is obviously something that eludes me. Help! Stuck!
Anyone got any ideas? I'm pretty new to the Oracle side of this, so don't hold back on offering "obvious" tips - what may be "obvious" to you gurus will most likely be black magic to me at this point ;)
Thanks for your help,

It's probably bad form to reply to my own post, but I've just repeated the problem on a clean machine, so I thought I'd submit a quick update.
OS: Windows XP Professional
Product: Oracle 9i Application Server Release 2 (9.0.3)
1) Install 9iAS with WebCache
2) Select "No Infrastructure"
3) Complete installation
4) Verify installation complete and 9iAS started -
http://localhost:7777/
5) Verify OC4J instance(s) created and started -
http://localhost:1810/
6) Attempt to list all sites -
...\j2ee\home>java -jar admin.jar ormi://127.0.0.1 admin password -list
Error: javax.naming.NamingException: Lookup error: java.net.ConnectException: Connection refused: connect; nested exception is:

Ok - I admit it - I'm dumb. What did I miss/forget/not grok?
Any pointers would be greatly appreciated.

The problem is addressed (see http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4665037):

Opmn fails with connection refused

Hi all,
I've successfully installed Oracle Application Server 10g AS R2.
After installation I could successfull login and access both Infra and Middle Tier using OEM, which were configured under a single Farm.
But unfortunately, after and when the server is restarted... opmnctl startall hangs with ons.log contents as below
08/06/23 16:25:14 [4] ONS server initiated

As a workaround I verified /etc/hosts file... it is as below

I'm performing the start-up & shutdown in the following order

Now... I'm able to access the Infra & Middle tier throgh OEM but the status is Unavailable. Moreover now they not under the Farm (Which they were earlier in).
Also it is giving error connecting to repository database.
Please anybody, who have come across this kind of problem, kindly guide me, where actually I'm missing.

Hi Adith,
Thanx a lot for the updates and correcting me. I've gone through the documents and corrected the way by which I was starting the services.
But... when I try to do opmnctl startall, now I again got struck up with this strange error in ons.log

I've gone through metalink and found out that this is a problem with SSL Authentication which been stated as a bug.
Can anybody answer my following queries...
1. Is it mandatory to enable SSL in 10g AS? Can we run server without SSL?
2. If not mandatory, then how to disable SSL?
3. If the handshake error is a bug, how to fix? Do I need to apply any patch for this?
Looking forward for immediate response,

Connection refused error when trying to to lookup EJB in iAS

Hi,
I tried to write a client that uses an EJB in an 9.0.3 iAS running on windows NT SP6, and the JNDI lookup keeps failing with the following error:
javax.naming.NamingException: Lookup error: java.net.ConnectException: Connection refused: connect; nested exception is:
java.net.ConnectException: Connection refused: connect
     java.lang.Object com.evermind.server.rmi.RMIContext.lookup(java.lang.String)
          RMIContext.java:134
     java.lang.Object javax.naming.InitialContext.lookup(java.lang.String)
          InitialContext.java:345
     void Samplecom.mind.ejb.stubs.AccountComplexStubClient.main(java.lang.String[])
          AccountComplexStubClient.java:24
I am using the following properties for the lookup:
env.putContext.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "ias_admin");
env.put(Context.SECURITY_CREDENTIALS, "ias_admin1");
env.put(Context.PROVIDER_URL, "ormi://localhost:23791/mindejb");
Where:
* 23791 is the port configured in the rmi.xml
* mindejb is the name of the module
* ias_admin1 is the correct password of ias_admin user
Similar properties worked for a stand alone oc4j. What have I done wrong?
Any help will be appreciated.
Thanks,
Avi

Hi -
I can resend what I think I would have said later on. No guarantees though ;-)
What you need to do is to look at the RMI port range allocated in the opmn.xml file for the OC4J instance you are trying to connect to. OPMN basically looks at the first number, and determines if the port is free. If it is, it will use it. If it's not, it will go to the next sequential number and try that, etc.
So if you have a defined port range of 3101-3200 and you only have one process, then it's a pretty safe bet (unless another rogue process has grabbed it) that the port you need will be the first one listed - 3101. If you specified two JVM processes to be started for the instance, then it's likely that 3101 and 3102 will be used.
I think that's what I'd written in the truncated text.
In our forthcoming 904 release, we're providing a port lookup service which will be able to be used by remote clients to discover the RMI ports used for OC4J instances. This will then avoid the client (and admins) needing to know and publish the specific ports used. Since OPMN itself knows which ports have been allocated, it can be queried by remote clients to find out where to connect. I've not seen the final spec, but I think this lookup will be transparent to the client in terms of code and will only require the addition of a prefix to the provider.url property used in jndi.propeties.
It's likely to be of a format such as opmn:lookup:ormi://<known-ias-host-location>.
Sorry about the truncation, it looks like that has now been rectified for the forums.

RMI Connection Refused through Firewall

Hi,
I am having problems making an RMI connection through a firewall. On the server outside the firewall I have my servlet application running in an OC4J container and inside the firewall I have an EJB listening on port 6666. I have setup the firewall to allow connections through on port 6666. If I telnet from the machine outside the firewall on port 6666 I am able to make a connection to the EJB. So I know the firewall has been setup to handle the connection.
I run the servlet application and when it tries to make the connection it gives an error:
javax.naming.NamingException: Lookup error: java.net.ConnectException: Connection refused; nested exception is:
java.net.ConnectException: Connection refused
When I do a snoop on the external machine to see what data is trying to be sent to the internal machine there is no data. When doing the telnet test there was data.
I have the same servlet application deployed on a machine internally and it is able to make a connection to the EJB. The only problem is either the configuration of the application server on the external machine or the firewall configuration.
Anyone able to help me see what I am missing?
Thanks
Shawn Clark

not sure what you mean by having a 'EJB listening' on port 6666. Do you mean actually having a socket listening within the EJB code? If so then that is a suspicious EJB activity.
If not then i guess you mean the ORMI listening port of the OC4J application. This is normally set on port 23791 to allow the RMI communication to flow.

When I try to log in from desktop I get "Connection Refused" message. How do I fix this?

I tried to activate Mozilla Firefox today using the normal & routine method, clicking on the Firefox Icon.
Each time I tried I got the same message "Connection Refused".
I went to the Firefox site and read the message regarding disabling Java, so I opened ADD ONS and Plug Ins and disabled Java.
Still no change, so I shut down and restarted my computer.
I keep getting the same Connection Refused message.
What needs to be done to restore Firefox?

Another user also reported a problem with the AT&T Yahoo home page in the past few minutes. When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
orange Firefox button (or Tools menu) > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site:
* right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
Then try reloading the page. Does that help?
