Omni Portlet - Web Service access outside firewall

According to http://download-east.oracle.com/docs/cd/B32110_01/webcenter.1013/b31074/jpsdg_portletconfig.htm#CEGECDBC
to access a web service outside the firewall we need to modify 'provider.xml'
From the JDEV HOME, I could see multiple 'provider.xml' files, Could some one help me with the exact 'provider.xml' file I need to modify and the entries to be modified.
note, we are using Jdeveloper 10.1.3.2.0
Thanks,
Kalyan.

Hi Kalyan,
You can find provider.xml related to omniportlet at the following location.
JDEV_HOME\jdev\extensions\oracle.adfp.seededoc4j.10.1.3.2.0\j2ee\home\applications\portalTools\omniPortlet\WEB-INF\providers\omniPortlet
We need to configure proxy here so as to enable omniportlet to access the websites outside the fire wall.
In Webcenter 10.1.3.2, we also have dependecy to configure webclipping proxy as well. So will have to do the same with webclipping's provider.xml too. You can find it at the following location.
JDEV_HOME\jdev\extensions\oracle.adfp.seededoc4j.10.1.3.2.0\j2ee\home\applications\portalTools\webClipping\WEB-INF\providers\webClipping.
You will have to add the following in the provider.xml
A) If you dont have any authentication for your proxy
<proxyInfo class="oracle.portal.provider.v2.ProxyInformation">
<httpProxyHost>Your_HOST_NAME</httpProxyHost>
<httpProxyPort>Your_Port</httpProxyPort>
<proxyUseAuth>false</proxyUseAuth>
</proxyInfo>
B) Basic Authentication
Basic Authentication
<proxyInfo class="oracle.portal.provider.v2.ProxyInformation">
<httpProxyHost>Your_HOST_NAME</httpProxyHost>
<httpProxyPort>Your_Port</httpProxyPort>
<proxyUseAuth>true</proxyUseAuth>
<proxyType>Basic</proxyType>
<proxyRealm>Your_Realm</proxyRealm>
<proxyUseGlobal>true</proxyUseGlobal>
<proxyUser>User_Name</proxyUser>
<proxyPassword>User_Passwd</proxyPassword>
</proxyInfo>
C) Digest Authentication
Basic Authentication
<proxyInfo class="oracle.portal.provider.v2.ProxyInformation">
<httpProxyHost>Your_HOST_NAME</httpProxyHost>
<httpProxyPort>Your_Port</httpProxyPort>
<proxyUseAuth>true</proxyUseAuth>
<proxyType>Digest</proxyType>
<proxyRealm>Your_Realm</proxyRealm>
<proxyUseGlobal>true</proxyUseGlobal>
<proxyUser>User_Name</proxyUser>
<proxyPassword>User_Passwd</proxyPassword>
</proxyInfo>

Enable Web Service access for a Web service-enabled client

Hi,
I want to access data in Oracle CRM On Demand from a Web services-enabled client. The "Oracle Web Services On Demand Guide" suggest the Web Services Access should be granted by Customer Care representative. By default, this access is enabled for the Administrator role for new companies. However my admin account can't access web services from a web enable client.
Can anyone please suggest me the setting/step that i need to enable Oracle On Demand Web service access from a Web services-enabled client?
Note: I am new to oracle on demand so my query can be a silly thing.
Thanks & Regards

I was able to resolve this issue. Actually, i was trying with trial account that don't allow the OCOD web service integration.

Name of Lockbox set in Remote Portlet Web Service?

Using the ALUI 6.0 IDK API, does anybody know how to get the name of the Lockbox a Remote Portlet Web Service is using?

Hello,
first: I don´t know anything about the right solution. I am unaware of the existence of the solution, because there were quite many of question about this multiple selection problem and I don´t remember a single "answer".
I can recommend you to simplify everything and create the functionality yourself. I have done that before to avoid these "Adobe-standard" problems. If you have a problem with autofill of the object, ask your WS to send you a single string and pass it yourself using scripting (JS).
And if you have problems with multiple selection, create your own field/ object. Get the string of values, parse it, create multiple lines of the dynamic table with some suitable tool to check/ select the rows you need (use checkbox for example, and your text as a table row). This way you can selected anything you want with no problems at all. It wil only cost you some extra work.

Secured Sybase Web Service with outside certificate authority

Hello,
I would like to use Secured Sybase Web Service with outside certificate authority, like Symantec. Could you let me know how I can create CSR for sending to Symantec? What other steps do I need to do?
Thanks,
Sudarat.

Hello Jason,
Thanks for your reply. The certificate authority require the CSR file before issue a signed certificate. If this is a signed certificate for IIS web server, I can create CSR from IIS. But I cannot use a signed certificate created from CSR of IIS with Sybase Web Service. The below steps are what I have tried.
1. I use CreateCert.exe with /r parameter to create CSR and private key.
2. I sent CSR to a certificate authority and they send back a signed certificate.
3. I have to combine a signed certificate from #2 with private key created from #1. Then use that file to specify with -xs{https …when starting the service.
Are the above steps what I have to do? If so, do I need to redistribute createcert.exe to my customers who want to use my application and how? Why I cannot use the signed certificate created from CSR of IIS?
Thanks,
Sudarat.

Newbie question: how to tell if account has web services access?

As the title suggests I am new to CRMOD though I have worked with other web Apis.
Right now I have a CRM account but keep getting the "capslock" response in my SOAP call. I think it is because the account is just a regular account and is missing certain rights. How do I tell the admin to grant my account those rights? I'm not sure how to make such a request in words they will understand.

Hello Daniel,
You need to identify your role. If you go to mysetup you would know your role.
Ask the admin to grant "Enable Web Services Access" prvilege to your role.
This should be fine.

Problem with accessing a web service from outside world

Hello SAP experts
I have a custom BAPI for which I have created a webservice.
If I login as an admin to the BOX where I have installed this SAP server and open an internet explorer window and give the URL, I can access the web service without any problem. This is just a simple BAPI that searches for some data from a table based.
However, when I give the same URL from a different PC, it can open the web service and in the fields if I give the data and click on send button, it fails with an error '500 Internal Server Error '.
I looked for the details of this error on internet and it says that this is some general error and solutions that it suggested doesn't help my scenario.
Has anyone seen this problem before? Any help will be highly appreciated.
Tks
Ram

i have tried the stack trace in the catch but as i said on the statement where i made the object for the service the program just exits. it didn't return any exception or any output.
thanx for refering me any answer.......

Web Service access with J2EE1.3?

Hi,
I'm relatively new to the whole Web Services technology, so my question might be dumb... but anyway:
What I'm trying to do is to write some code to access a Web Service (I'm not trying to make one, it's supplied by an outside provider). We currently use WebSphere 4, so that puts me with J2EE 1.3. I started looking for tutorials on java.sun.com, and strangely, I couldn't run any one of them (tried SAAJ and JAX-RPC). I then inspected the J2EE API specifications and found out that the packages used in the tutorials do not exist in J2EE 1.3, only in 1.4. So, my question is - do I have to use J2EE 1.4 to use Web Services, or there's a way to access them in 1.3, and if so, how?
Thanks,
Alex Savitsky

You can write an AXIS client for any web services that can run from JDK1.3. See http://ws.apache.org/axis for details.

Project Server 2010 Web services access with Client Certificate Authentication

We switched our SharePoint/Project Server 2010 farm to use client certificate authentication with Active Directory Federation Services (AD FS) 2.0, which is working without issue. We have some administrative Project Server Interface (PSI)
web service applications that no longer connect to server with the new authentication configuration. Our custom applications are using the WCF interface to access the public web services.
Please let us know if it is possible to authenticate with AD FS 2.0 and then call
Project Server web services. Any help or coding examples would be greatly appreciated.

what is the error occurred when the custom PSI app connects?
can you upload the ULS logs here for research?
What is the user account format you specified in the code for authentication?
For proper authorization, the “user logon account” in PWA for the user needs to be changed from domain\username to the claims token (e.g.
'I:0#.w|mybusinessdomain\ewmccarty').
It requires you to manually call the UpnLogon method of
“Claims to Windows Token Service”. if (Thread.CurrentPrincipal.Identity is ClaimsIdentity)
{ var identity = (ClaimsIdentity)Thread.CurrentPrincipal.Identity; }
if (Thread.CurrentPrincipal.Identity is ClaimsIdentity)
var identity = (ClaimsIdentity)Thread.CurrentPrincipal.Identity;
Than you need to extract UPN-Claim from the identity.
Upload the verbose log if possible.
Did you see this?

Web Service Access to a extension field

Hello All:
   Scoping against solution capability, how easy, or at all possible, is to access a extension fields to a native ByD business Objects via web services? In my specific case, the E-Commerce Sales Order Creation Web Service.
   But the question is pretty general, This can be a data retrieve web services as well? Any limitations? does it needed to be rebuild by SAP? or can we generate them by ourselves?
   Also, if in future new extension required on web services, can this process be done after implementation and go live? Without too much trouble?
   Any documentation will be greatly appreciated! Thank You!

This is doubtful as it is a Standard service (we use it for several different solutions).. and is the same across all tenants and I do not think it can be applied as a custom one off..
asking your dev coach would probally be your best bet.
Another solution for you would be to have a simple Read,Update Service you write that just deals with your extension fields... so after an order is created you can update your field on the sales order, or read the value given a specific sales order.
Unless this has changed it is my understanding that you have to add the Extension field via the Development studio not the Key user tools if you wish to have access to it in the Studio for releasing a webservice like I described above.(Most my work so far has involved integrations and the standard webservices)

Web Service access

I am trying to access a web service that I created in Visual Studio. I've downloaded the sample code from http://www.simplified-tech.com/website/webapp.nsf/webpages/ArticlesBBWebServices and modified it to query my web service. When I run my app in the simulator it just stalls at the "Sending" portion. The same result happened in the original web service sample (the language translator). I then created an MDS project to connect to my web service and another MDS project to access the language translator. Both of them worked with no problem. The problem is that I do not want to use MDS since it requires a BES to run the apps you create. I just want to develop in JRE so I can load my app on BB's in the office. The sample article didn't work becuase the web service had changed since they posted it so I changed the input values to reflect the new web service format and it still did not work. On my web service I created a log file to tell me who and when the last call was to the service. When I access it from my MDS project I get a record in the log but when I try it from the JRE I don't get any record entry in the log.
I'm new to JRE so syntax kills me most of the time. I don't know enough to fix the problem. Does anyone have any full samples that connect to a web service that currently work?

Generating Ruby Web Service Access Classes from a WSDL

If you have tried to consume a web service from Ruby you surely have noticed how annoying is to write manually all the Ruby code just to invoke a service with complext input parameters' structure:
- You have to know what do the input parameters, their structure and type look like;
- You have to write Ruby classes for them to encapsulate the structures;
- You have to instantiate these classes and pass the objects to the web service proxy class;
- You have to interprete the output parameters.
All this is not impossible of course, but if you are just consumer of the web service and not the developer, if you don't have the exact documentation, you have to read the WSDL description of the service and create the Ruby classes (structures) for the parameters.
Fortunately there is a small, though handy tool, called wsdl2ruby.rb. It accomplishes all these boring tasks for you.
In the following example I will try to show you how wsdl2ruby can be used to generate Ruby classes for accessing a SAP NetWeaver web service, called CreditChecker1 (a web service for checking if a person is reliable credit consumer).
To generate the necessary classes we will create a ruby script. Let us name it ws2rgen.rb. Here is what this file looks like:
# Import the wsdl2ruby library.
require 'wsdl/soap/wsdl2ruby'
require 'logger'
# Callback function for the WSDL 2 Ruby generation options.
def getWsdlOpt(s)
 optcmd= {}
 s << "Service"
 optcmd['classdef'] = s
 #should work but doesn't, driver name is derived from classname
 #if you specify both it breaks, same thing for client_skelton
 #optcmd['driver'] = s
 optcmd['driver'] = nil
 #optcmd['client_skelton'] = nil
 optcmd['force'] = true
 return optcmd
end
# Create logger.
logger = Logger.new(STDERR)
# Create WSDL2Ruby object and generate.
worker = WSDL::SOAP::WSDL2Ruby.new
worker.logger = logger
# WSDL file location.
worker.location = "http://mysapserver:53000/CreditChecker1/Config1?wsdl"
# Where to generate.
worker.basedir = "temp"
# Set options.
worker.opt.update(getWsdlOpt("Service"))
# Heat.
worker.run
The procedure is straightforward. First we create the WSDL2Ruby object, set its properties location and basedir and then set all other options via the callback function getWsdlOpt(). For further information about these parameters one could consult the source code of wsdl2ruby or contact the developers. Nevertheless the default options are pretty satisfactory. With the last line we start the generation. Two Ruby files will be generated in the temp folder, which is a subfolder of the script's current folder. Please, create the folder "temp" before executing the script.
This generates two files. The first one is CreditChecker1Wsd.rb, containing the necessary data structures:
require 'xsd/qname'
# {urn:CreditChecker1Vi}areReliable
class AreReliable
@@schema_type = "areReliable"
@@schema_ns = "urn:CreditChecker1Vi"
@@schema_qualified = "true"

@@schema_element = [["response", ["ArrayOfboolean", XSD::QName.new("urn:CreditChecker1Vi", "Response")]]]
def Response
 @response
end
def Response=(value)
 @response = value
end
def initialize(response = nil)
 @response = response
end
end
# {urn:CreditChecker1Vi}isReliable
class IsReliable

@@schema_element = [["response", ["SOAP::SOAPBoolean", XSD::QName.new("urn:CreditChecker1Vi", "Response")]]]
def Response
 @response
end
def Response=(value)
 @response = value
end
def initialize(response = nil)
 @response = response
end
end
# {urn:java/lang}ArrayOfboolean
class ArrayOfboolean < ::Array
@@schema_type = "boolean"
@@schema_ns = "http://www.w3.org/2001/XMLSchema"
@@schema_element = [["boolean", ["SOAP::SOAPBoolean[]", XSD::QName.new("urn:java/lang", "boolean")]]]
end
# {urn:com.sap.scripting.test.services.creditchecker.classes}Person
class Person
@@schema_type = "Person"
@@schema_ns = "urn:com.sap.scripting.test.services.creditchecker.classes"
@@schema_element = [["age", "SOAP::SOAPInt"], ["name", "SOAP::SOAPString"], ["purse", "Purse"]]
attr_accessor :age
attr_accessor :name
attr_accessor :purse
def initialize(age = nil, name = nil, purse = nil)
 @age = age
 @name = name
 @purse = purse
end
end
# {urn:com.sap.scripting.test.services.creditchecker.classes}Purse
class Purse
@@schema_type = "Purse"
@@schema_ns = "urn:com.sap.scripting.test.services.creditchecker.classes"
@@schema_element = [["color", "SOAP::SOAPString"], ["money", "Money"]]
attr_accessor :color
attr_accessor :money
def initialize(color = nil, money = nil)
 @color = color
 @money = money
end
end
# {urn:com.sap.scripting.test.services.creditchecker.classes}Money
class Money
@@schema_type = "Money"
@@schema_ns = "urn:com.sap.scripting.test.services.creditchecker.classes"
@@schema_element = [["amount", "SOAP::SOAPDouble"], ["currency", "SOAP::SOAPString"]]
attr_accessor :amount
attr_accessor :currency
def initialize(amount = nil, currency = nil)
 @amount = amount
 @currency = currency
end
end
# {urn:com.sap.scripting.test.services.creditchecker.classes}ArrayOfPerson
class ArrayOfPerson < ::Array
@@schema_type = "Person"
@@schema_ns = "urn:com.sap.scripting.test.services.creditchecker.classes"
@@schema_element = [["Person", ["Person[]", XSD::QName.new("urn:com.sap.scripting.test.services.creditchecker.classes", "Person")]]]
end
The second file is CreditChecker1WsdDriver.rb. In it you can find a generated child class of SOAP::RPC::Driver, containing all methods of this web service, so you don't need to add every method and its parameters to call the web service.
require 'CreditChecker1Wsd.rb'
require 'soap/rpc/driver'
class CreditChecker1Vi_Document < ::SOAP::RPC::Driver
DefaultEndpointUrl = "http://mysapserver:53000/CreditChecker1/Config1?style=document"
MappingRegistry = ::SOAP::Mapping::Registry.new
Methods = [
def initialize(endpoint_url = nil)
 endpoint_url ||= DefaultEndpointUrl
 super(endpoint_url, nil)
 self.mapping_registry = MappingRegistry
 init_methods
end
private
def init_methods
 Methods.each do |definitions|
 opt = definitions.last
 if opt[:request_style] == :document
 add_document_operation(*definitions)
 else
 add_rpc_operation(*definitions)
 qname = definitions[0]
 name = definitions[2]
 if qname.name != name and qname.name.capitalize == name.capitalize
 ::SOAP::Mapping.define_singleton_method(self, qname.name) do |*arg|
 __send__(name, *arg)
 end
 end
 end
 end
end
end
There is a problem with this script, since the Methods array is empty. I suppose it is due to the imports in the SAP NetWeaver WSDL, maybe wsdl2ruby is not mighty enough to handle these WSDL imports. When I succeed in overcoming this, I will post again in this thread to let everybody know.

Hi,
I find Ruby to be really tough to consume SAP WebServices. For simple scenarios like currency conversion may it is good. But for complex scenarios such as Purchase Order entry etc..I found it very annoying to use wsdl2ruby and see that it didnt generate correct proxies.
Until wsdl2ruby is stable enough to support complex datatypes, authentication etc. my recommendation is to use JRuby and use Java Proxies generated by NW Developer studio until pure Ruby's web service support improves.
Following link might be of interest w.r.t wsdl2ruby

The EnrollmentPolicyWebService log on the other hand tries to tell me:
The Certificate Enrollment Policy Web Service failed to initialize. Confirm that the Certificate Enrollment Policy Web Service is properly installed. Try to restart Internet Information Services (IIS) by using iisreset.exe. If the problem persists, enable
tracing in the web.config file, restart IIS, attempt to obtain policy information from any client, and then contact Microsoft Customer Service and Support with the trace file information. Unknown HResult Error code: 0x80131902
I am kind of lost and I'd appreciate some help...

Java Web Services accessing rmi server

Hi,
I want to access the rmi server from a java web services.My java web services is running under Sun application server9.The rmi server is not using any application server.Please help me to sort out the problem.
Bye
Binay

What's the problem exactly? I assume you understand that the RMI server has to run like any RMI server, it has to bind itself into a Registry; the Web server acts as an RMI client so it has to look up the Registry to get a remote reference so it can call the required remote methods.
