Https via upstream proxy fails

Something has changed at an upstream proxy that we use.
now in chrome we try any https sites we get:
Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED)
In IE we just get page not found http 400 bad request.
What should I be saying to the upstream proxy folk to get them to fix this.
I used to be OK

How do I send HTTP request to a server via a proxy server in JDK 1.4?

JDK 1.5 's URL class provides an overloaded version of openConnection() which accepts an object of type Proxy using which we can establish connection with a remote server via a proxy server, but JDK 1.4 doesn't provide any such overloaded version. How do I do that in JDK 1.4? Even if I had a class that can create HTTP packets for me, then I could have established Socket connection with the proxy server and sent the HTTP packet to it. Is there a way to do that also?

There are some system properties, which can be set with System.setProperty [http://java.sun.com/j2se/1.4.2/docs/guide/net/properties.html]

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.

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).

Push data from BW 3.5 to XI 3.0 via ABAP proxy

Hi,
I have the following scenario: I´m in BW 3.5 trying to send data to XI 3.0 via ABAP proxy. I´ve already found a "How-to" to do build this scenario, but something does not work. I think that problem is when a try do the logon from BW to XI because I got the message "logon data not provided" on http service in XI. I´ve already configure an RFC Destination(SM59) as R/3 connection(type 3) and another as HTTP connection to R/3(type H) and both are correct. Someone knows where I configure the user/pass to logon from BW Intergration Server to XI Integration Server?

Hello fellows!
I discovered that my problem was configuration on SXMB_ADM transaction.

Http to abap proxy

Hi ;
Can somebody help me by sending screenshots for a http to abp proxy scenario.
I am new to sap xi .
i need a http cleint also,
Thnx

Hi
Here in this case it is a http client to abap proxy. For http client (sender CC) u wud not req sender agreement. Follow the below link for http client config:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/66dadc6e-0a01-0010-9ea9-bb6d8ca48cc8
And u shud have the DT,MT, MI, Mapping in place. U wud do the req confir in ID and recv agreement will be for proxy. For that follow this link.
/people/prateek.shah/blog/2005/06/14/file-to-r3-via-abap-proxy
Combine these two and u will get ur thread anwsered for sure. In this post the file will be replaced by http client. remeber no need to sender agreement.

Hi Chaitanya,
Looks like the ABAP code failed during a call to DB. You would have to sit with ABAPer fot this to debug and see where exactly the exception is being raised. Set a debug point in Proxy code and debug the message. You can use sproxy to test this.

Lookup of alternativeServiceIdentifier via CPA-cache failed for channel

Hi,
In RFC(ECC) to File(PI) scenaio i am facing the following error in sender CC:
Error in processing caused by: com.sap.aii.adapter.rfc.afcommunication.RfcAFWException: lookup of alternativeServiceIdentifier via CPA-cache failed for channel SND_RFC
-CC' (f455868123qq3bba4c3dc3dbf93ed1b, party '', schema 'TechnicalSystem', identifier 'ECC#110')
I have done the following for RFC to File scenario:
ECC side:
1. Created a RFC and tagged it to BAPI
2. In the ABAP program, i am calling the RFC like below:
CALL FUNCTION 'Z_HR_OUTBOUND_DATA2'
IN BACKGROUND TASK DESTINATION 'Z_HR_OUTBOUND_DATA2'
EXPORTING
INTERFACE =
IMPORTING
FILENAME = FILENAME
RETURN = RETURN
TABLES
ITAB10 = ITAB10
P_STATUS = P_STATUS
COMMIT WORK.
3. Created a RFC destination using SM59
RFC detination : Z_HR_OUTBOUND_DATA2
Connection type : TCP/IP
Enabled Registered Server Program
Program ID : ECCTOPI_OUTBOUND
Gateway host : ECC's host number
Gateway service : ECC's service number.
In PI side:
I have created :
1 DT for File Rcvr
1 MT for File Rcvr
1 SI for File Rcvr (async)
1 MM (sender RFC and receiver File)
1 OM
1 CC with RFc as sender with the following parameters:
Communication component : ECC's component
application server (gateway) : ecc's gateway
application server service(Gateway) : ecc's service number
Program id : ECCTOPI_OUTBOUND
inital connections 1
max. connections 1
And also gave ecc's details in application server , s/y number, auth. mode, logon user ,
pwd, ecc's client number
1 CC with File adapter and file content conversion
1 receiver determination
1 interface determination
1 sender agreement
1 receiver agreement
When i am executing the ABAP program in R/3 I am getting the following error:
Error in processing caused by: com.sap.aii.adapter.rfc.afcommunication.RfcAFWException: lookup of alternativeServiceIdentifier via CPA-cache failed for channel SND_RFC
-CC' (f455868123qq3bba4c3dc3dbf93ed1b, party '', schema 'TechnicalSystem', identifier 'ECC#110')
Please let me know if any of my steps are wrong and how to rectify this error and make
the scenario working.
Thanks for your help.

I have mentioned the Adapter specific parameters properly.
It contains :
For ECC s/y(i.e for RFC)
   Logical system : DECCLNT120
   R/3 system ID : DEC
   Client 120
For PI (i.e for File)
   Logical system : DPICLNT100
   R/3 system ID : DPI
   Client 100
Since i am sending the Response of the RFc to the file, i have used a Service interface where i am passing the RFC.Response as Request.
if i am passing the RFC directly as i/p in Source operation of Operation mapping then it doesn't pick up the response in the souce message of the mapping program present in Operation mapping.
So i am passing the same SI_Sender_RFC in the Sender Agreement and it gives the error:
Error in processing caused by: com.sap.aii.adapter.rfc.afcommunication.RfcAFWException: senderAgreement not found: lookup of binding via CPA-cache failed for AdapterType RFC, AdapterNS http://sap.com/xi/XI/System, direction INBOUND, fromParty '', fromService 'DEC_RFC', toParty '', toService '', interface 'Z_HR_OUTBOUND_DATA2', NS 'urn:sap-com:document:sap:rfc:functions' for channel 'CC_LOTUSNOTES_OUTBOUND_SND_RFC' (channelId c78f5a88787131a09384c07c2db0e93b)
why is it so?

How to Displaying Employee Photo in ESS Who's Who via Reverse Proxy?

Dear Gurus,
I have a bit of problem to displaying employee's photo in ESS Who's Who via Reverse Proxy.
In my landscape, end-users are only able to reach the Reverse Proxy server, not the actual SAP server itself.
In Who's Who, when displaying the employee's info, the URI for the photo is generated using the actual SAP server name.
Illustration:
- the URI we expect: https://portal.domain.com/sap/bc/contentserver?.....
- the URI we get: http://r3server.domain.com/sap/bc/contentserver?....
Does anyone know where/how I can set the URL (hostname and protocol part) to refer to my reverse proxy?
Or is it because SAP is using an absolute path rather than the relative one?
How do we go about it?
Thanks in advance.

HTTPS and a Proxy server?

Does the plugin-in still not work with HTTPS and a proxy server?
From plug-in docs -
"Java Plug-in supports http, ftp, gopher and SOCKS v4 protocols through the proxy server. Currently, Java Plug-in does not support https (SSL). "

Hello
I am making HTTPS calls from within my applet code and this works fine using the basic Java Plug-in support for HTTPS.
This means my code basically does:
URL url = new URL("https://myhost.com/servlet/Test");
URLConnection conn = url.openConnection();
etc..
We are using Java 1.4.2. I've read in the "How HTTPS Works in Java Plug-in" for 1.3, that the plugin uses the browsers API for making HTTPS connections. Is this still the case for 1.4?
My basic problem is that it all works fine if the browser is NOT configured to use a proxy server. If a proxy server is configured we get the following Exception in the client:
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 400 Bad Request ( The data is invalid. )"
I have read that "Sun's Java Secure Socket Extension (JSSE) library allows you to access a secure Web server from behind a firewall via proxy tunnelling. However, JSSE expects the proxy's reply to the tunnelling request to begin with "HTTP 1.0"; otherwise, it throws an IOException" (http://www.javaworld.com/javatips/jw-javatip111_p.html)
The article talks about using the JSSE library but it seems to be assuming the client is an application not an applet.
How do I use JSSE from within an applet if all the proxy information I seem to need to set in the JSSE code is held by the browser?
Will JSSE support proxies returning responses beginning HTTP 1.1 in the future?
Any help on this would be greatly appreciated.
Many thanks
mark

Enabling Oracle Management Service to Access My Oracle Support
Unless online access to the Internet is strictly forbidden in your environment, Oracle Management Service should be enabled to access My Oracle Support. This access is necessary to enable updates and patches to be downloaded, for example.
At minimum, the following URLs should be made available through the firewall:
aru-akam.oracle.com
ccr.oracle.com
login.oracle.com
support.oracle.com
updates.oracle.com
About the dontProxyfor Property
When you configure the Oracle Management Service or a Management Agent to use a proxy server, it is important to understand the purpose of the dontProxyFor property, which identifies specific URL domains for which the proxy will not be used.
For example, suppose the following were true:
You have installed the Oracle Management Service and several Management Agents on hosts that are inside the company firewall. These hosts are in the internal .example.com and .example.us.com domains.
You have installed several additional Management Agents on hosts that are outside the firewall. These hosts are installed in the .example.uk domain.
You have configured Enterprise Manager to automatically check for critical software patches on My Oracle Support.
In this scenario, you want the Oracle Management Service to connect directly to the Management Agents inside the firewall without using the proxy server. On the other hand, you want the Oracle Management Service to use the proxy server to contact the Management Agents outside the firewall, as well as the My Oracle Support site, which resides at the following URL:
http://support.oracle.com
The following properties will prevent the Oracle Management Service from using the proxy server for connections to the Management Agents inside the firewall. Connections to My Oracle Support and to Management Agents outside the firewall will be routed through the proxy server:
proxyHost=proxy42.example.com
proxyHost=80
dontProxyFor=.example.com, .example.us.com
PS: Cygwin has nothing to do with My Oracle Support connection. Cygwin is ONLY required for agent deployment using agent push from OMS.

Initiating Upstream Proxy request on Cache-Miss (ACNS)

1. Client has two (2) tier Content Routing network architecture:
Client<->Tier_2_CE <-> Tier_1_CE <-> Origin_Server_01
2. Client does not have EXPLICIT PROXY configured on browser pointing to Tier_2_CE
3. Network uses Content Routing to redirect client requests to appropriate Tier_2_CE (proximity search using CZF, channel assignment)
4. SCENARIO_PRE-POSITIONED: (WORKS FINE)
4.1 Client requests PRE-POSITIONED content from CDN
4.2 Client request redirected to Tier_2_CE
4.3 Tier_2_CE services request from PRE-POSITINED content (i.e. cache-hit)
5. SCENARIO_NONE-PRE-POSITIONED:
5.1 Tier_2_CE configured with outgoing HTTP proxy pointing to Tier_1_CE:
"http proxy outgoing host X.Y.Z.W 8080 primary"
5.2 Tier_1_CE configured with inbound HTTP proxy
"http proxy incoming 8080"
5.3 Tier_1_CE configured with outgoing HTTP proxy pointing to Origin Server:
"http proxy outgoing host A.B.C.D 80 primary"
5.4 ISSUE
5.4.1 Client request for NONE-PREPOSITIONED content reaches appropriate Tier_2_CE
5.4.2 Tier_2_CE does not make Upstream request for content on Cache_MISS
6. QUESTIONS
6.1 Can you point me to reference documentation around proxy configuration (environments not using (a) WCCP (b) explicit proxy configuration)
6.2 Provide some configuration guidance/samples around this scenario
regards,

Thanks Mary,
It appears as if the configurations that are outlined on that page either
(1) assume that the subscriber / client has
EXPLICITLY configured a proxy server in their browser that points to their Tier-2/edge CE farm or
(2) the access infrastructure into the CDN (essentially edge routers) are configured with WCCP
Let me know if this is not the case, as I may be mis-reading & mis-configuring.
In my setup, the Tier-2/edge CE's are configured to
(3) listen for inbound requests on (80, 8080) and
(4) point to an upstream proxy A.B.C.D:8080
ISSUE
(5) In normal operating conditions (i.e. content IS pre-positioned), client requests are fully serviced from CDNFS on the Tier-2/edge CE's
(6) When content is not available on CDNFS (none-prepositioned), a cache miss occurs on the Tier-2/edge CE's.
(7) What is the best way to configure my Tier-2/edge CE's so that they ALWAYS query upstream proxy for content in the event of a CACHE-MISS on local CDNFS?
(8) How do I enable this ((7) above) without having to use rules on the Tier-2/edge CE's?
Thanks again,
regards,
