Connect refused in Exchange Portlet

Hi,
I am trying to config the exchange portlet using URL-services and basic authentication. When I get to create web provider, the following error show up:
An error occurred when attempting to call the providers register
function. (WWC-43134)
An unexpected error occurred: ORA-29532: Java call terminated by uncaught Java
exception: java.net.ConnectException: Connection refused (WWC-43000)
An unexpected error occurred: java.net.ConnectException: Connection refused

at HTTPClient.HTTPConnection$EstablishConnection.run(HTTPConnection.java:574)
(WWC-43000)
Any idea?
Thanks.

Do you mean the IsItWorking page or the test.asp in exchange portlet?
They both work fine.
Thanks. I meant neither of these but the test page for provider. The
installation instructions document refers this in the file
"INSTALLING.MICROSOFT.EXCHANGE.55.PORTLETS.html" and under
"Configuring the Web Provider" section. You have to make sure
the provider's servlet alias
http://your_oracle_http_server_hostname:port/servlet/exchange55
is running fine before specifying this URL in the provider registration
screen.
Hope it is clear now :-)
Thanks,
Amjad.

Mail refuses to connect to my Exchange Server

I have an Exchange Server which also functions as an IMAP server. I cannot get mail to connect this server using the IMAP protocol. Thunderbird on the same machine connects to this exchange server just fine using IMAP. And Mail does not have problem connecting to other IMAP servers. Any idea on where I can look to troubleshoot?

I'm in the same boat and have been banging my head against this all day. Have you found an answer yet?

EXCHANGE PORTLET IN CLUSTER MACHINE

Hi,
I was setting the exchange portlet, but the machine residing IIS and the outlook is in a cluster how can I configure the portlet in the cluster?, is there any special instruction to setting the portlet?, I have to do the same twice in each machine or this is not supported?
Thanks a lot.
Cecilia Vega

Hi Cecilia,
I have not tested Microsoft exchange portlets in a cluster environment. But I feel these portlets should work fine in a cluster environment too.
A few questions though,
1. "Outlook is in a cluster", can you please elaborate on this. As the there is no dependency on Outlook for the portlets to work.
2. Can you let me know details of Cluster environment and the version of the Windows/ IIS and Exchange server that you are using.
Answer to the above questions will allow me to answer with more specifics.
But here are a few points for setting up Microsoft portlets in a cluster environment:-
1. Once you set up the Replication and Clustering in IIS, then you will be pointing to one IIS machine where the .asps are hosted. And the failover will be taken care by the clustering environment, you will not have to do any additional settings.
2. You need to keep in mind that ASP sessions do not fail over to other nodes in Microsoft Clustering. This means that clients will need to reestablish the connection if a failover occurs on the server.
Please get back if you face any issues.
Take care,
Manoj

Error while connecting to Microsoft Exchange server using javamail: "com.sun.mail.util.MailConnectException: Couldn't connect to host, port: host name , 993; timeout -1"

Whats wrong with my code?
Please help!!!!

You're using the "imaps" protocol, but you've set properties for the "imap" protocol. Change all the property names from mail.imap.* to mail.imaps.*.
Also, get rid of all the socket factory properties.
If you still can't connect, see these connection debugging tips.
Most likely you're using the wrong host name or port number. In almost all cases, it's better to just let JavaMail choose the correct port number.

Missing parameters for Exchange Portlet

In the Exchange Portlet installation document on page 15 under
Stage 3. Changes to zone.properties
the line shows
servlet.exchangeAppProv.initArgs=provider_root=c:\exchange, sessiontimeout=1800000
it should read
servlet.exchangeAppProv.initArgs=provider_root=c:\exchange, sessiontimeout=1800000, debuglevel=1
This will allow the execution of the servlet/exchangeAppProv/ URL and verification of the exchange Portlet Provider configuration
null

Yes, I have been using $_REQUEST.
The test script looks like this:
<?php
$latin_name = $_REQUEST['latname'];
$common_name = $_REQUEST['commname'];
if ($latin_name == "")
$latin_name = "Not available";
$common_name = "Not available";
$connection = mysql_connect("localhost", "user", "pword") or
die ("Unable to connect");
mysql_select_db("balloonflash") or die ("Database not
found");
$query = "INSERT INTO species (latName, commName) VALUES
('$latin_name', '$common_name')";
$result = mysql_query($query) or die ("Unable to execute
query: " . mysql_error());
mysql_close($connection);
?>
It seems like the script is not triggered at all when I run
the Flash form from HTML - I don't even get the default values
entered into the database. Actually, yes I do, my mistake - but the
variable values are not being passed over.
The HTML source generated looks like this:

Client-Proxy-Server: Connection refused

I was meddling with a client-proxy-server toy program.
Pardon my poor code construction. I have never had any previous knowledge in this field.
I have created a client side program with my main that handles IO serially.
ProxY consists of 2 unscynchronized threads each interacts with client and server respectively.
Packet exchange within ProxY is relayed using a PacketBuffer object.
Server consist of a single threaded service. Below is the code for my main.

          //Start Client side;

Outlook Exchange Portlet

Hi,
We've been trying unsuccessfully for a few days now to get a portlet to connect to our Exchange 5.5 server. Our basic requirement is to have a portlet within our Oracle Portal that can display mailbox statistics (such as the number of unread messages) and that allows the user to 'drill-down' into the Outlook client and access their Inbox and Calendar etc.
We were sent a small portlet from an Oracle consultant but have had no joy in getting it to connect to Exchange.
Would really appreciate any ideas or comments anyone can offer. Surely others have tried something like this before, and surely it cant be too difficult?!
Thanks,
Don

Hi,
Have a look at the Exchange portlets provided by Oracle: http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/SAMPLES/WEBPORTLETS/V2/EXCHANGEPORTLET/EXCHANGE55.ZIP. There's also a version for release 1 on PortalStudio.
It doesn't allow you to drill down into the Outlook client, but instead uses Outlook Web Access to "drill down". I've installed the Exchange 2000 portlets and they work great. You can view your inbox, calendar and contacts as portlets and it's fairly easy to use the supplied code to create your own portlets e.g. for displaying tasks or notes.
If you absolutely need to "drill down" into the Outlook client, you need to run your Portal page as an Outlook Today page (inside Outlook). Look at msdn.microsoft.com for information on how to make your own Outlook Today page.

Web Browser Management Connection Refused

Since upgrading from my old Panther PowerBook to my new Tiger one, I have lost the ability to manage my Netgear router and my HP network printer via Safari. Strangely, my Netgear router at home actually works better (I used to have to go back into OS9 to change settings as Panther didn't work at all), but the devices on the corporate network at work don't seem to like Tiger. I get this message:
(111) Connection refused
I don't really now how to troubleshoot this...
Oh, and it's the same with other people's Tiger Macs - and from 10.4.3ish on.
Thanks!

I don't think it can be that simple because it is consistent across more than one machine and it doesn't work from Firefox either (just checked that).
I think it must be to do with being on the corporate network, so I need to know what might have changed in the Mac OS that would cause this issue. I recently lost the ability to access the Exchange server, which turned out to be due to a change in Mail's SOCKS access under 10.4.7 (fine under 10.4.6). Something similarly obscure (to me) could be causing this other issue, but I've no idea what...

JavaMail - Connection refused

Hi, all,
I have a trouble connecting to INBOX folder. Here is the code:
     Session session = Session.getInstance(new Properties());
          Store store = null;
          Folder folder = null;

          folder = store.getFolder("INBOX");
          folder.open(Folder.READ_WRITE);          The parameters passed to connect() method of the sore are correct on 100%. However, I receive the following exception in line with store.connect();:

Indeed, the trouble was with exchange server. It hasn't been configured to get mail from mailbox. API works fine.As an advice I recommend to contact administrators about exchange server settings.

Office 2013 - The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete.

Hi Team,
Just purchased and downloaded Office Home Premium and having trouble with Outlook. For what ever reason, I am unable to create account/add my email address ([email protected]) into the program. Through the set-up process it continuously
tells me that it is unable to connect to Microsoft Exchange, and that it must be online or connected to complete. In the end, it comes up with this pop-up listing a file. Something like that. Any pointers on how to resolve this or are a lot of people having
this problem..
Also, I installed this on my laptop (OSX 10.8.2)
and it worked fine, but not on my desktop (Win8 Pro 64-bit)
Thanks
Andi

Hello,
Does OWA work?
Does this issue occur on other users?
In Exchange 2013, most of the internal and external client becomes to use Outlook Anywhere(RPC over http).
Please make sure the autodiscover.domain.com is included in the certificate.
Thanks,

Hi I am having the same issue. Brand new computer, using Office 365 and trying to set up Outlook 2013 on Win 7 machine. OWA works fine. But cannot set up Exchange on my desktop.
I don't know what you mean by "In Exchange 2013, most of the internal and external client becomes to use Outlook Anywhere(RPC over
http).
Please make sure the autodiscover.domain.com is included in
the certificate."
Can you please walk me through this? Thank you.

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?

Expected behavior of the Exchange portlets in release 2

I've installed the Exchange portlets in release 2 successfully. Everything works - Inbox, Calendar, Contact list. However when you update the portlet with required information i.e. Inbox user name, server, # of message rows, the portlet displays the view, but once you go to a different page and then decide to return to the page with the Exchange portlets, you need to enter that very same information again. Is this the way it is suppose to work???
Please share your experiences.
Thanks,
r/ George

George,
This may be a pain for you, but could you please walk me through the steps that you took to get the exchange portlets working? We are trying to install the exchange5.5 portlets. We are currently using Portal release 9.2.1.2.14 (i think that's it - latest release) and have upgraded to 9.0.2.4 via the December PDK we downloaded. We have also made the appropriate setup to the IIS/Exchange server and can view the test.asp pages that were provided. Do you need to deploy an .ear file on OC4J for the exchange5.5 portlets like you do for the exchange2000 portlets? Any help would be appreciated and we have read the documentation included with the Dec. pdk.zip release to no avail. Thank you.
Jeremy

Problems with SSH: Connection Refused

Greetings fellow Arch users,
I have hit a bit of a snag that I could really use some extra help getting around. I've tried everything I can think of (and everything that Google thought might work) and I have my back rather against a wall, so I thought I'd come here to see if anyone can offer some advice.
To make a long story short, I am a college student and am attempting to set up an ssh server on a desktop at my house so I can access it remotely from the college. I have the computer set up and the server running, however I am having difficulty making connections to it from my laptop. I know that the server is running, because I can log into it both from the server itself (sshing into local host) and from my laptop when I use the internal IP address.
The server is on a static IP address within the network(192.168.0.75), and my router is configured to forward TCP port 1500 to it (I'm using 1500 as the port for my ssh server). However, when I attempt to log into the ssh server using my network's external IP address, the connection is refused. I used nmap to scan my network and found that, even though the proper ports are forwarded to the proper place as far as my Router's configuration interface is concerned, port 1500 is not listed as one of the open TCP ports. I also, to test it, temporarily disabled the firewalls on both the server and the client. That didn't help. The command that I am running is:
ssh -p 1500 douglas@[external ip address
As I am really not sure what is causing this problem, I don't know what information to provide. So here is everything that my inexperienced mind sees as likely being important. If you need anything more, let me know and I will do my best to provide it.
Here is the sshd_config file from my server.

Thank you guys ahead of time. Getting this server operational is hardly critical, it is just a side project of mine, but I would really like to see it working.

Okay, so I finally have the opportunity to try and log in from a remote network. And. . . it doesn't work. Which is just my luck because I now need to wait an entire week, at least, before I can touch the server again. Anyway, running ssh with the maximum verbosity I get this output:
douglas ~ $ ssh -vvv -p 2000 address
OpenSSH_6.3, OpenSSL 1.0.1e 11 Feb 2013
debug1: Reading configuration data /home/douglas/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug2: ssh_connect: needpriv 0
debug1: Connecting to address [address] port 2000.
debug1: connect to address address port 2000: Connection timed out
ssh: connect to host address port 2000: Connection timed out
It takes a minute or two for the command to finish with the connection timeout, as one would expect. And yes, I am reasonably sure that the address that I am using is my home network's external IP. It is dynamic, but I checked it before I left which was just over an hour ago. I guess that it may have changed. I'll know that for sure in the morning, when my server sends me an automatic email with the network's current address. In the meantime I am operating under the assumption that the address I am using is correct. What else could be the problem?

Mac computers in the office are not able to connect to our exchange server.

We started facing this problem about a month ago in our office where the apple computers can not connect to the exchange server via outlook or applemail or anything for that matter. All the other computers can connect to the exchange server with no problems
and the apple computers can even access the exchange server via OWA but the outlook and applemail apps would not connect to exchange. We have tried even deleting and re-creating some accounts on the apps but they still would not connect. At this point I am
at a complete loss and I looked everywhere through google to find out if anyone else has faced this problem but to no avail.
A little background information. This specific problem started happening after there was an un-expected series of power outages to the servers and they were shut down un-expectedly. I personally restored the servers and turned on all the services and made
sure everything was up and running after the power outages and everything was working fine. Also the first instance of the problem with the mac computers only happened two days after the servers were back up and running again and they had no issues in those
two days.
Right now we do not have that many mac users in our offices (only 3-4 users) and I have instructed them to use the OWA in the meanwhile but it is however an inconvenience to them. By now you may have realized that I am not a very experienced server admin
and I would really really appreciate any help. I extend my thanks in advance for any insight.

Hi Martin,
Thanks for the reply.
Right now I have Apple mail and Outlook installed on my mac laptop and both the applications do not connect to the exchange server. Apple Mail simply does a long process when I give my credentials to create my account and then it gives an error saying it
could not find the server while outlook quickly tells me that either the username or password is incorrect. At the same time I can connect to the server through outlook on my windows computer without any problems whatsoever.
From your reply, I gather that the VIA headers only affect Apple mail and should not affect Outlook app on the mac but right now, neither apps are connecting to the exchange server.
Either way I am trying to find out how to remove the VIA headers because it does not seem that we are using Kemp on the exchange server. Right now I do not have the in depth knowledge that I need because I was not involved in the implementation of our server
system, that was taken care of by a service provider and I was put in charge of mostly simple admin work. Now we are out of contract with the service provider so pretty much everything has fallen onto my shoulders.
If possible, would you mind pointing me in the right direction to finding out if I am using a L7 load balancer and how I would go about removing the VIA headers?
