Web Access via a proxy server not working

We are developing an application on weblogic that needs to connect to the internet,
login and retrieve informatoin back into weblogic. We have a problem where this
works on a direct connection to the net, but via a proxy server we get:
<21-Aug-03 10:18:38 BST> <Info> <net> <000900> <Could not open connection

Failed to login to D&B - com.dnb.globalaccess.ServerException
Does anyone have any idea's on what this is or means? Has anyone come accross
similar issues with proxy servers?

Thanks Criag.
For anyone else's reference, my odiparams.bat file now has a line something like:
set ODI_ADDITIONAL_JAVA_OPTIONS=-Dhttp.proxyHost=myproxyhost.com -Dhttp.proxyPort=proxyPortNumber -Dhttp.proxyUser=someUserName -Dhttp.proxyPassword=somePassword "-Dhttp.nonProxyHosts=127.0.0.1|someInternalHost.com"
Note the -Dhttp.nonProxyHosts (which is the proxy exceptions list) is in quotes to escape the pipe character (for windows at least).

Web access to ip phones is not working although it is enabled on CUCM

Dear All,
i enable web access for ip phone ,but still not able to access the phones through web.
Regardsm
Moath

What call manager version are you using? If you're on 8.x there is security by default and if you're on an older version it's possible you have security enabled (CTL files) which would be causing your phone not to trust it's TFTP configuration file, which is where the web access setting is passed to the phone. If you look at Settings > Status Messages on the phone do you see anything such as trust list update failed? If you see that it's likely an ITL file issue. If you go into Settings > Security, and delete the ITL from the phone it will download a new one automatically from your TFTP server. Once the ITL is correct the phone should trust the TFTP configuration file and update the web access setting on the phone.

Printing via Network Printer Server not working

I have three Macs on a local Network, PowerBook Pro, Mac Pro and Mac Mini. Printing facilites are provided by an Epson printer connected to a Networked Print Server, both the PowerBook Pro and the Mac Pro print without any issues, However when i try to print from the MacMini i always get a communications error. I have another location where i have a similar set up and i get the same error at that location.
The Print Servers and Mac's are connected to the network via Wireless, if i try to use Ethernet i get the same issues.
Any ideas?
Thanks
John

The Mini runs on Lion (10.7) and Lion want to have all network participants in the same local domain since Airdrop.
Check that the printserver uses local as domain in the network settings instead of (as often preset) workgroup

How to access Internet through proxy server

Please help... I cannot get Internet access through a proxy server at work.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Web-UI error message "Access via 'NULL' object reference not possible"

I need some help, I'm not a Basis person but I need to get this connection problem resolve.
This problem is in our DEV ICWeb system. After logging in to Web-UI, I got a error message "Access via 'NULL' object reference not possible". We have 3 clients (100, 220, & 310) in DEV and all 3 clients are giving me the same error message.

HTTP connection from OSB web service to external system via a Proxy Server

Dear experts,
May I know has anyone tried to use HTTP protocol to send a request from OSB web service to external system via a proxy server? Heard that we need to establish some sort of tunnel (socket) to talk to Proxy Server. Can you please any have sample code or configuration steps to share?
Thank you very much!!

Adding Proxy Servers
Use the Summary of Proxy Servers page to add and configure Proxy Server resources and make them available in Oracle Service Bus as a system resource. You must be in an active session to configure or reconfigure Proxy Server resources.
1. If you have not already done so, click Create to create a new session or click Edit to enter an existing session. See Using the Change Center.
2. Select System Administration > Proxy Servers.
3. Click Add.
4. In the Name field, enter a name for the Proxy Server resource. This is a required field.
5. In the Description field, enter a short description for the Proxy Server resource.
6. In the Host-Port Parameters section, enter the following information:
1. In the Server Host field, enter the host name or IP address of the Proxy Server. This is a required field.
The Server Host name for the Oracle Service Bus proxy server must be identical to the server host name of the actual proxy server.
2. In the Clear Text Port field, enter the Proxy Server clear-text port number.
3. In the SSL Port field, enter the Proxy Server SSL port number. You must enter either a clear text or SSL port number.
4. Click Add.
You can configure multiple Proxy Servers for each Proxy Server resource. This enables Oracle Service Bus to perform load balancing and offer fault tolerance features for the Proxy Server resource.
7. If the Proxy Server performs proxy authentication, enter a user name in the User Name field, and the associated password in the Password and Confirm Password fields.
These fields are optional, and required only if the Proxy Server is secured.
8. Click Save to create and save the Proxy Server resource in the current session.
9. To end the session and deploy the configuration to the run time, click Activate under Change Center.

Accessing Distributed Queue In a Cluster via the Proxy Server

 I am running WL 8.1 SP2. I have a configuration where I have 3 servers (on two
 different machines) running in a cluster. I have a separate server on a 3rd machine
 running the cluster proxy server for a single point of access to the cluster.
 I have configured a distributed queue and a distributed topic, each targeted
 to all servers in the cluster.
 Now I have a JMS client which is a separate java application that is trying to
 connect to the distributed queue and topic in the cluster. If the client connects
 directly to one of the cluster machines, it is able to successfully interact with
 the JMS queue and topic. But if it attempts to connect via the proxy server it
 gets an error saying the queue and topic does not exist.
 So what am I missing? Do I need to configure a separate JMS server on the proxy
 server and add that as part of the distributed queue & topic (this didn't seem
 to allow me to add anything outside of the cluster). Is there any special configuration
 in the proxy to pass through JMS requests? I'm currently using a WL logic server
 as my front-end proxy server but does anything change if I want to use Apache
 with the WL Proxy plug-in??

 Yup... That makes sense...

 One option I have used frequenly is specifying java.naming.provider.url as
 cluster address (e.g. t3://server1:7001,server2:7001
 You may also want to look into tunnelling...

Will creative cloud work via a proxy server

We use a proxy server for all our internet connections. Will creative cloud work via a proxy server?

Hi - I'm i a similar position to the OP, we've bought a cc2014 individual licence but I work in a government organisation with proxy server and strong firewall and we can't download even the desktop manager. When I spoke to support they said it was unlikely I'd be able to get it to work through our system, and even if we upgraded to a teams licence we'd still have a problem as the indidual computers would still need a clean connection through to the adobe servers to activate.
The document linked only talks about the Packager and the Teams/Enterprise licence, so is there just no solution for anyone with a single licence that has to work via a proxy server? Would a Teams licence solve these problems?

When using a proxy server at work, Deezer page does not load normally?

When using a proxy server at work, Deezer page does not load normally, but when I go home and use connection without proxy, everything is fine.
It loads, and some features on the website work, but the look is not the same. Over the proxy it shows just text on the left side of the screen and I can't choose some of the options.
When I go home and use my home connection without proxy, there are no problems, everything is OK.
Could you please solve this?

I found that after Firefox v29, a LOT of my settings and 
add-ons were changed / reset. Try this;
'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]'''''
 While you are in safe mode; 
'''''Firefox Options > Advanced > General'''''. 
Look for and turn off '''Use Hardware Acceleration'''. 
Then check ALL of your settings. Browser and add-ons. Then restart.

Server proxy is not working

Hi Experts,
I have a scenario from jdbc to SAP.I have made serverproxy.The proxy was not working.I have test the proxy backend it is working fine,but i am staring jdbc channel the data was not insert in to the database table in sap.I have checked in sxmb_moni in sap r/3 system is showing scuessfully,but data was not sent to proxy.I have put one break point in the code for debugging the proxy.But data was not comming to breakpoint.Kindly help me.
Thanks
Ravi

Hi,
Make sure that you have not done any changes in your XI structure recently otherwise regenerate the proxy and then try agin.
Secondly if you have not done any changes then it's ok. Just one thing, have you used Commit Work just after modifying/inseting the value into database table. If not use this and then try again.
It seems that smoethig went wrong at R3 side because you said data is successful in R3 MONI, so data is reaching to R3 but not going into proxy.
When you kept the break point then were you able to see the debugger screen in R3?

Sarvesh

IC WEBCLIENT: Access via 'NULL' object reference not possible

Hi,
Iam working in ABAP, and learning CRM ABAP on CRM5.0 IDES Demo system I was trying to create a new WebIC by copying one view from CRM_IC to ZCRM_IC bsp application. Following are the steps I following according to Cook book documentation.
1. I copied BuPaDisplayCustomer view and controller from CRM_IC to ZCRM_IC from
    BSP_WD_WORKBENCH by selecting CRM_IC and runtime profile = 'DEFAULT'.
2. Created a runtime profile from SPRO->CRM->IC Webclient->Customer specific modifications->Define
   runtime profile.
3. Copied the 'DEFAULT' runtime profile to my new profile 'Z_COOKBOOK'. Assign 'ZCRM_IC' by
   clicking on 'Controller and substitues'.
   BSP       Replaced Controller         BSP                 ReplacmentController
   CRM_IC BuPaMoreContactView    Z_CRM_IC         BuPaMoreContactView
4. Define IC Webclient profile:
    SPRO->CRM->IC Webclient->Define IC Webclient profile->Copy the DEFAULT profile and assign it to
    'Z_COOKBOOK',
5. Assigned the Webclient profile to the user from t-code 'PPOMW'. Selected 'USER' from the
    existing 'Position' and Goto->Detail object->Enhanced obj descrption.Selected IC webclient from the
   list and created Infotype assigned Webclient profile 'Z_COOKBOOK'.
6. Execute the ZCRM_IC from SE80 by rightclick and Test. Here is my problem,Iam receiving the
   following error in the webpage.
     The following error text was processed in the system CR7 :
           Access via 'NULL' object reference not possible.
    The error occurred on the application server CR7_01 and in the work process 0 .
    The termination type was: RABAX_STATE
The ABAP call stack was:
      Method: SET_MODELS of program CL_CRM_IC_BUPADISPCUSTOME=====CP

      Function: HTTP_DISPATCH_REQUEST of program SAPLHTTP_RUNTIME
      Module: %_HTTP_START of program SAPMHTTP
I check the CRM services and all are active, using IE8 web browser. I just copied the view and controller
from CRM_IC into Custom BSP application i.e., ZCRM_IC.
Above error is occuring even If i run the standard CRM_IC BSP application and select one simple view.
from SE80.
Not sure whether any additional configuration or any special roles to be assigned to the Webclient profile.
Thanks,
Venn.

Hello Vaish & Ankit,
Can you check what is the dump occurred in transaction ST22?
I hope you guys are working with HR data. So, i think some object is not passed(internally) correctly in RFC.
Please debug the RFC by keeping the breakpoint from webdynpro application, then you will come to know what is not passed when we execute the RFC from R/3.

Thanks Rama,
Acutally i accidentally commented the lo_nd_student = wd_context ....etc
this line was commented .
i have one small requirement to fetch data from local customised table and fill the same to internal table and bind that to table node.
my table node is student having attributes as name , city and number , all are of type strings.
now i created one custom table zstudent having ID - char of length 10,
name of type string
city of type string
num of type string
i have inserted records
but when i use select query to fill data from this zstudent to my internal table of type lt_student type wd_this->elements_student ,
im getting same above error.
