SSL connection refused
Hi
I am trying to connect from sap portal through web dynpro to PI but I get the following exception:
"Cannot find resource for bundle Java.Util.PropertyResourceBundle key could not create SSL socket... Connection refused."
Any idea how this could be fixed?
regards
Yuval
That error implies that Open Directory either isn't configured or isn't running or isn't set for secure access, or possibly that DNS isn't set up or isn't resolving the target of the openssl command correctly.
From the errno.h file:
#define ECONNREFUSED 61 /* Connection refused */
Check the settings and maybe then the logs on the Open Directory server.
I get that exact error when the Open Directory server isn't enabled for SSL with a certificate selected, too.

SSL connection refused: errno=61
I'm trying to follow this guide to import OD servers SSL certificate for my client server: http://support.apple.com/kb/ht4183
my os version is 10.6, so the guide states that I need to import the certificate manually.
But when I try to run the command, that the guide states:
openssl s_client -connect myServerName:636
I get:
connect: Connection refused
connect:errno=61

Decision Service calls failing with connection refused
Hi All,
Breifing of the bpel process - Async bpel process XX_BPEL_ASYNC_002 calls decision services and a sync bpel process XX_BPEL_SYNC_001.
We have moved to cluster 10.1.3.5.0 from 10.1.3.3.0 and the deployement of the bpel process and the decision service done on two nodes i.e., node51 and node55.
But the bpel process is able to call the decision service only when the node 51 is UP and running, but if node 51 is down and node 55 is up and running it is failing with connection refused error. It is also working when 55 is DOWN and 051 is UP.
the exact error is:
exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Connection refused.
We are using file based repository.
It is failing when it tries to call particular url:
http://loadbalancerurl:7777/orabpel/domain001/XX_BPEL_ASYNC_002/1.0/decisionservices.decs
Can anyone please help me or advice me for finding some solution.
Thanks
SreejitHi Fatsah,
It has been a while since we resolved this problem. But these were the basic steps that we had taken.
The receiver was configured a File adatpter with FTP:
Port: 10021
Connection security : FTPS (FTP using SSL/TLS) for Control and Data Connection
Command Order: AUTH TLS,USER,PASS,PBSZ,PROT
Problem: The message was blocked in our firewall.
FTPS in this case used 10021 as the control port and the firewall allowed to pass the control request.
Once the connection was accepted at the control level, it generated a random port number to pass data on the channel.
This random port number was blocked in the firewall.
We monitored the data port numbers generated at firewall. Then we configured the firewall to open any port number between the specific IP addresses of the sender and the receiver. That resolved the problem.
Hope this helps!
Please give points if this is helpful.
Thank you.

Javax.mail.MessagingException: Connection refused: connect on localhost
Hello,
I am using Tomcat5.0.28 for a javamail servlet program. I am giving the hostname as localhost. After entering the input details in my html file, i get the error- "javax.mail.MessagingException: Connection refused: connect; nested exception is: java.net.ConnectException: Connection refused: connect " .
can anybody help me regarding in solving error.
Thanks.First, you're using a very old version of JavaMail. Please upgrade. Some of the properties you're setting aren't supported in that old version.
Second, you don't need the socket factory properties, get rid of them.
Finally, it looks like you're trying to connect on port 143 using SSL. Port 143 is the non-SSL port. That's probably not going to work. Still, it looks like something is refusing to let you connect at all. If you really can telnet from the same machine your program is running on to the same server machine on port 143, then you probably have some sort of firewall that's preventing your program from connecting. Please post the entire debug output if it still fails after correcting the problems above. (Move the setDebug call to before the getStore call.) -

What is this problem ?
Can someone help us ?
Thanks in advanced.but i am not send to the client when i accept the client connection immediately ,It doesn't matter when you send to the client. The answer is still the same. You send to a client via the socket you accepted from that client. That's what it's for.
for example :
first client_A connect to Server (port 2222) , than Client_B connect to Server (port 2222) , finally Client_C connect to Server (port 2222)You don't need to keep telling me the port number. If the ServerSocket is listening at port 2222 they will all connect via port 2222. They don't have any choice about that.
and all not close the connection, but if I want to send some msg to Client_B from Server, how can i send the msg to client_B ?Via the socket you accepted from client B. I've already answered that.
it's just like you said "you don't have to do anything about that. " ?Is that a question?
You don't seem to have much idea about client-server socket programming. Have you read the Custom Networking tutorial? -
Hi, i've installed BI Server EE on a virtual machine.

Also check your firewall settings. I also could not get localhost to work, I had to use the actual IP address of the machine, ie not 127.0.0.1. Use telnet hostip 5432 to check if you can get a connection. For my situation once telnet would connect, then JDBC started working too. Then localhost started working too. -

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
08/06/23 16:53:15 [4] Logging disabled
08/06/23 16:57:43 [4] ONS server initiated

As a workaround I verified /etc/hosts file... it is as below
127.0.0.1 localhost.localdomain localhost
192.168.6.183 oravis.dsrc2.com oravis
I'm performing the start-up & shutdown in the following order
START DB Tier
Start Database as
Make sure your are in DB Home
$ sqlplus "/as sysdba"
SQL> startup
Start DB Listener as
Make sure your are in DB Home
$ lsnrctl start RETEK

cd $ORACLE_HOME/bin

Make sure your are in Middle Tier Home
cd $ORACLE_HOME/opmn/bin
$./opmnctl stopall
Stop Infrastructure Services as
Make sure your are in Infra Home
$ ./opmnctl stopall
Stop Infra Listener as
Make sure your are in Infra Home
$ lsnrctl stop [listener_name]
Stop Infra Database as
Make sure your are in Infra Home
$ sqlplus "/as sysdba"
SQL> shutdown immediate
Stop Infra iAS Console
Make sure your are in Infra Home
cd $ORACLE_HOME/bin
emctl stop iasconsole
Stop Middle Tier iAS Console
Make sure your are in Middle Tier Home
cd $ORACLE_HOME/bin
emctl stop iasconsole
Stop DB Tier
Stop Listener as
Make sure your are in DB Home
$ lsnrctl stop [listener_name]
Stop Database as
Make sure your are in DB Home
$ sqlplus "/as sysdba"
SQL> shutdown immediate
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.
-MaheshHi 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
08/06/24 10:26:02 [4] ONS server initiated

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,
Regards

Connection refused in Mission control
Hi !
I created a simple application just for demo and I start it with
java prim.Prim 100000000 -XX:+UnlockCommercialFeatures -XX:+FlightRecorder
But I can't connect, when doing 'Start jmx-console' I get connection refused after a while.
The same problem when starting the application in NetBeans .At least that makes sense (JConsole not working either). Okay, so something is messed up regarding local attach on your machine. Let's try not using local attach. What happens if you try adding the following to the command line, and then set up a connection in JMC manually (click the "new custom connection" icon in the JVM Browser)?
-Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=7091 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -

Connection refused, but works on diff computer
Ok, i'm opening a connection to a web server using ssl (jsse) and this WAS working great. But now when I try to run the same code that was working on this computer (and still works upstairs) i get:
java.net.ConnectException: Connection refused: connect
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305)
at ..............
The line of code that is causing this problem is
OutputStream outputStream = null;
outputStream = conn.getOutputStream(); <- RIGHT HERE
the conn was setup and is not null because I can getURL() on it and it's context has been setup, so everything seems to be ok with the connection but once I try to get an output stream it blows with that connection refused exception. I have set doOutput to true aswell:
conn.setDoOutput(true);
Like I said, this code works on a different computer now and used to work on this one. If anyone knows what could have happened to this machine I could appreciate any help.
(used to work but now it doesn't box)
JDK 1.4.1
Intel processor
Windows 2000
(still works box)
JRE 1.4.1 (no jdk)
Intel processor
Windows NT
Thanks a bunch
-DaveAnd can you ping the other computer from the one that doesn't work?

Add User/ Communication Exception: Connection refused!
Hello,
I've searched the entire forum , for sample code for adding a user to the Active directory.However, the code that I use , refuses to budge past this line, and gives a
*Problem creating object: javax.naming.CommunicationException: mydc.antipodes.com:389 [Root exception is java.net.UnknownHostException: mydc.antipodes.com]*
// Create the initial directory context
LdapContext ctx = new InitialLdapContext(env,null);
When i change the ldap url to 'ldap://localhost:389', it gives me this exception
*Problem creating object: javax.naming.CommunicationException: localhost:389 [Root exception is java.net.ConnectException: Connection refused: connect]*
I also could not follow , how the LDAP url is formed, and those CN=,DC= attributes.I also typed in the LDAP url in the browser, and an External Protocol request popped up , that had a search for people names and email.
Can someone please enlighten me , on where i was going wrong.I'm working on a windows XP machine with JDK1.6 with Netbeans.
The same functionality is also done , in .NET using the activeds.tlb file and it is working fine.Is there a way in Java, where i can added a reference/COM component , in the same way as above , and add users?

mydc.antipodes.com is my domain controller, it's most certainly not yours !
If you are running Active Directory (although I somehow seem to think that you are not), the LDAP URL will contain the fully qualified DNS name of your domain controller and the distingushed name of your Active Directory domain (or part thereof).
Because you are most certainly do not have access to my domain, nor would my domain controller be registered with your DNS server or listed in your hosts file, that explains why you receive the Unknown Host Exception.
Now the reason why I think you aren't runnning Active Directory is that you say you are running on Windows XP and when you use ADSI (winnt://localhost) it all works.
The ADSI provider WINNT, uses the Windows NT/LM API's which are used to access either the local Windows account store which is sometimes referred to as Security Accounts Manager (SAM), or a Windows NT 4 domain. (Actually it could be used to access Active Directory, albeit using the NT/LM API's rather than LDAP). The JNDI LDAP provider supports the LDAP protocol, it does not support NT/LM.
If on the other hand I'm wrong, and you do have Active Directory present in your network, either ask the admin for the DNS name of the domain controller,and the distinguished name of your domain, look up the LDAP Resource Records (RR's) in your DNS, or use the Windows LDP.EXE tool, leave everything blank, hit the connect button and look at the Root DSE for the naming contexts and dns host name values.
