Web Services, WS-Security and WebServices Assembler

Two questions about WebServices and jDev 10.1.2
1 - What underlying technologies is WebServcies Assembler using to generate WS code? Axis? Suns' WS developer kit? Other?
2 - We need to utilize WS security and 509 certs to secure some web services, can WSA handle this? If so, what's the general recommeneded approach? If not, any other recommendations?

1 - What underlying technologies is WebServcies Assembler using to generate
WS code? Axis? Suns' WS developer kit? Other?A. JDev uses its own stack to generate this code
2 - We need to utilize WS security and 509 certs to secure some web services,
can WSA handle this? If so, what's the general recommeneded approach? If
not, any other recommendations?A. Web Service Security is supported in 10.1.3

How to import a web service into labview and make the assembly strong named signed?

I have used the web services tool to import my .net project files. I am then putting them into clearcase. In order for my dll's to work on a network im getting the error that they need to strong named signed. Is there anyway of strong name signing them with in the web services tool, or modifying the dll's after they've been created? Thanks for any help!

dbell0971,
I appreciate your willilngness to help on this issue. However, it doesn't seem like we are on the same page here.
When you import a webservice it creates an assembly. That assembly is .NET. In general you cannot run an assembly on a shared drive unless it is "trusted". You can make the assembly trusted by adding some classes and properties to it (i.e. strong signing it)- http://msdn.microsoft.com/en-us/library/xc31ft41.aspx
However, since WE are not creating the assembly, LabVIEW is, then we don't have the source code so we can't just strong sign it.
The question is simple- Can the Import Web Service Utility strong sign the assembly it creates?
Thanks,

Web Service Sender security

Hello All,
We are integrating our POS (CLASS) application to PSCD... We are using standard SAP XI scenario..
Webservice to PI to ERP (proxy).
In POS client is using VB code to connect PI via web-service..
Sender webservice set basic authentication (User-ID/password)..
This user ID and password were stored in CLASS database, unfortunately password is NOT encrypted in CLASS data base..
Our internal audit was not happy password being not encrypted in CLASS database..
MY question is:
Is there any other way can we invoke this sender webservice with out user ID and password being stored in CLASS database.
I am using cash-point external cash-desk..
THanks
John

>Is there any other way can we invoke this sender webservice with out user ID and password being stored in CLASS database.
one way is using certificate authentication. This way you dont need passing user and password. Search SDN for the client certificate authentication. Basicallly the external system share their trust certificate with PI. Talk to Basis team about this.

Web services on SAP and JCo

Hi I have two questions:
1) I'm using a third party connector (JCo based) which is able to expose RFC/BAPIs into Web Services. (I know I could do this with SAP directly as well on ECC 5.0 and up, but for now let's say I have to use the JCo connector). If I write a custom RFC and want it to be called through that JCo connector, what are the steps that I need to go through to properly configure the custom RFC? Is there any documentation written for that?
2) In some other scenarios I need to call standard SAP web services. Some web services are transactional and commit/rollback needs to be called explicitly. What is the best practice for that? Do I need to make a custom RFC from the standard one, and add commit into it, and then expose it as a web service? Anyway for me to call that web service and commit in one connection?
Thanks much in advance,
Ye

Consuming an External Web Service using HTTPS and WS Security

Hello everyone,
I'm having a problem setting the security information in a SOAP header using a generated ABAP Client Proxy to consume an external web service that requires a User ID and Password in the Header section of the SOAP message. I need to use HTTPS. I'm on a WAS 7.01 SP08 system so from my readings, SAP is supposed to be able to add the username and password into the header section of the message. I can't seem to get SAP to add this information added to the header.
Here are the steps that I have taken to set the security values.
1) Created the client proxy from the WSDL in SE80. Basic Authentication on the Configuration tab was turned on automatically.
Note, Transport Security is set to None. I cannot change it.
2) Created an outbound set user name profile in transaction WSPROFILE with the appropriate username and password.
3) Added the profile to the default port in transaction LPCONFIG as an outbound under the WS Security section of the screen.
When I called the external Web Service, I got back the following error message:
com.ibm.wsspi.wssecurity.SoapSecurityException: WSEC5509E: A security token whose type is [http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken] is required.
So, after reading through this Forum, I saw that I needed to use the SOAMANAGER. I set up a Proxy in the SOAMANAGER and manually created the Logical Port. This was the only way I could figure out how to set the Authentication Settings in the Logical Port to "User ID / Password". I then entered the User ID and Password.
However, I am still getting the same error message. I feel I am close but missing some small configuration to tell SAP to use WS Security with a Username token.
I'm not sure what I'm doing wrong, so any help would be appreciated.
Thanks,
Stephen

I had this error again so I thought I would post my solution:
The issue is SAP needs to know the certificates being used by the web site being called. These certificates are automatically installed in your browser but need to be manually installed in SAP. This is what I did:
How to find/install new certificates
Make sure you run Internet Explorer as an Administrator so you can export the certificates
Go to the web site that SAP is trying to call in Internet Explorer
Double click on the lock in the address bar
View certificates
Find the certificates that are being used
Tools --> Internet Options --> Content --> Certificates
Click on the “Trusted Root Certification Authorities” tab
Find the certificate identified in step iii
Export as a CER certificate
Click on the “Intermediate Certification Authorities” tab
Find the certificate identified in step iii
Export as a CER certificate
Go to STRUST in SAP
Import the Certificates in the “Anonymous” or “Standard” SSL client
Save
RESTART the ICM via t-code SMICM <-- Critical!!!

Error trying to secure Web Service through OWSM and OAM

Hi all.
We are trying to secure a web service using Oracle Web Service Manager and Oracle Access Manager. We have deployed it into two HTTP Servers. The intended business flow should be:
1. The WSC make a SOAP request signed with a X.509 v1 client certificate.
2. The OWSM Gateway intercepts this request and apply the defined policy:
a. Verify Signature.
b. Extract of credentials
c. OAM Authenticate Authorize.
3. Then OAM apply the defined rule:
a. Credential validation and extraction of security tokens
b. Authentication against OID security attributes
We have protected with OAM the end-point web service URL for authentication and authorization. But we are getting an error when we invoke this web service:
/The Web Service call failed. The service returned a SOAP fault with the
message: Authentication Fault: Invalid User Session Token/
It seems that OWSM Gateway are processing policies defined well, but th error became accesing to OAM authentication and authorize. We have tried to enable OAM debug system, but if we configure it, OAM are unable to start. So we are not able to obtain a more detailed error.
T.I.A.

Try re-configuring the AccessServerSDK AccessGate using the configureAccessGate command in the tools directory. It may be possible that the key pairing is corrupted.

Secured web service for secured AM method

Hello,
I need to invoke method of secured Application Module (jbo.security.enforce = Must) from secured web service.
I have a simple java class with Configuration.createRootApplicationModule ... and a web service built for this java class.
I found I have to authentificate users twice. First time when invoking web service (this is ok) and second time when creating application module instance.
The problem is I can get name of user logged in web service but I cannot get his password. So I cannot login to application module with the same user.
How can I force adf business components to use user authentificated in web service to use him/her as adf bc user?

Hi Mayank,
Chapter 7, Custom Serialization of Java Value Types, of the Web services developer guide may be a good place to get started.

How to save web service request key and response value in cache to reduce calling the service for same type of requests

Hi
I have a web service which return the response based on the request key.
I need to save the key and the response value in cache for around 30mins
to reduce the web service calls for better performance.
Appreciate if any once can share a sample code

using System.Runtime.Caching;
public List<string> cachingwebserviceresponse()
{//Create a cache key
string strParameters = "1234";//Create a cache value holding object
List<string> results = new List<string>();//Create a cache
ObjectCache cache = MemoryCache.Default;//Assign key for the cache
string cacheKey = strParameters;//Check whether the key exists in the cache//If exists assign the values from the cache instead of calling the webservice//else call the web service and add the response to the cache
if (cache.Contains(cacheKey))
results = cache.Get(cacheKey);
else
{ //calling the web service client
using (service.webservice fd = new service.webserviceContractClient())
{ //Call the web service function to get the results
results = fd.DataSearch(strParameters);
} //Create the cache expiration policy. I have created for 30 minutes.
CacheItemPolicy cacheItemPolicy = new CacheItemPolicy();
cacheItemPolicy.AbsoluteExpiration = DateTime.Now.AddMinutes(30); //Add the response to the cache based on the key
cache.Add(cacheKey, results, cacheItemPolicy);
return results;

Not able to access web service with axis and tomcat

Dear all
i am trying to access web service using axis in tomcat.
i downloaded axis-bin-1_4.zip, unzipped it and installed it properly in tomcat.
i had tested axis, its working fine.
i had created a simple java class(a sample class from book) and deployed it in axis. i also created a client(a java consol class) for accessing that web service. but its giving error. i have no idea why this is comming.
plz point me in right direction.

Web Service Issue - Security or Coding problem? *HELP*

Hello all - I am stuck on a particular problem, which I've posted under flash player but also will post here in the event that it's my issue, and not a security/player issue.
I have built a video player in Flash/ AS3 which communicates with WSDL web services using the as3webservice code package from wellconsidered. The player makes a call at startup to check a user's progress in a series of videos, and updates that progress by talking to the web service as the videos are played back.
Tested locally, it works flawlessly. As soon as the player is uploaded, however, the web service' hangs' - so no fault is produced, but it seems to just never connect. This is presumably because the SWF is on one server, the web service on another. I've tried uploading it to two different servers, both different than the web service server. I'm trying to avoid moving the web service to the same server that hosts the SWF.
I've tried adding a crossdomain.xml file to the root and subdirectories of the server that hosts the web service:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM
"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
    <site-control permitted-cross-domain-policies="master-only"/>
    <allow-access-from domain="*"/>
    <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>
I've also tried playing with the SWF publishing options (Local Access only vs. Network only options), but no solution seems to help. I know it's not just the web service i"m using, because public web services (such as the ones found on webservicex.net) don't connect either.
I'm at the end of my rope, and am wondering if this is a Flash Player security issue, or something I need to reconsider from my side (such as using a different web services package).I am wondering if a crossdomain.xml does not help, what other possible areas do I need to look at? If there is an article someone could point me to, or a simliar situation they've been in, i'm iopen to all suggestions.
Thanks so much...fg

You can generally check what the player is doing from the browser by using firefox with the firebug plugin. For example you can see the crossdomain permission requests or other urlrequests and responses. This is a useful way to debug as it sometimes shows issues or at the very least means you can eliminate one potential cause of the issue if there are no obvious problems there.
If you don't have firefox/firebug, then (if you can) post a url with the swf in it that exhibits the error and I or someone else can check it for you and report back.

Define Web Services in XI and call Web Services from XI

Xi guys,
I want to create some Web services in XI that will do the following things:
receive an XML message over SOAP (from BEA WebLogic), execute 2-3 calls to an external HTTP Web Server from which I will get a response, export a file into another system, and return the response to the WS client.
As far as I know, I will have to create a Configuration scenario in XI that will contain all these steps (obviously with the help of BPM) and with the help of the Wizard, I will produce the WSDL, the function of which the Web service client will be able to call. I have some questions on that:
a) Is there a way to define with XI only one Web Service that will contain 3-4 function to do different things? Or one Web Service corresponds to one Configuration scenario?
b) Also do I need a Sender Agreement and a Sender SOAP communication channel?
c) Is there a way to construct the WSDL before creating the configuration scenario? Because BEA WebLogic people need it to start development.
Best Regards
Evaggelos Gkatzios

hi,
a) Is there a way to define with XI only one Web Service that will contain 3-4 function to do different things?
     Or one Web Service corresponds to one Configuration scenario?
b) Also do I need a Sender Agreement and a Sender SOAP communication channel?
Ans:
     If you are create a SOAP communication channel and Sender Agreement then One WSDL used
     One Configuration scenario.Another configuration you need to create another WSDL.Because at the
     time of creating WSDL you need to give a service name and communication channel.
     If without communication channel(using proposal consept creating WSDL) you can use that various
     senarios if your sender structure is same.(this time WSDL have the pipeline address with help
     of message interface fine the mapping and gave the output).
     If you create with SOAP communication channel and Sender Agreement WSDL is more secure.
     with out communication channel is not a secure one.
     If you go with (without sender CC) you can create and gave a WSDL before Scenario.
     If you have sender CC then after creating a scenario only you can able to gave WSDL.
     If you are createing with sender cc then you need to give a URL
     [http://<host>:<port>/XISOAPAdapter/MessageServlet?channel=:SenderService:SenderCC]

Web Service WLS9.2 and WLS6.1 SOAP compatibility

We have a Web Service (running on WLS6.1) which has been published for a long time, and many customers have developed their own clients.
Now we must upgrade our Web Service from WLS6.1 to WLS9.2. In practice we had to re-develope the Web Service starting form the original WSDL.
The new WSDL is identical to the original one, and the business code inside has obviously been kept the same.
The new Java Test Client that we generated with clientgen (WLS92) works fine, but we need to guarantee total compatibility for all the clients developed for the 6.1 version.
Unfortunately testing our new Web Service (WLS9.2) with our old java Client (developed with WLS6.1), we found that the SOAP implementation of arrays has changed, and therefore the old client is not compatible with the new Web Services.
Is this a known issue? Is there a workaround or a solution to this problem?

Hi
Thanks for your reply
I downloaded OC4J 10.1.2.0.2 and ran it as as a standalone server.
I read the blog you linked and made the changes to the web.xml for the webservice. All of which I was able to do using the property palette in jdev 10.1.2.1.0.
I deployed my webservice to my oc4j standalone server and it appeared as a new application. I editied the orion-web.xml for the new application manually.
When I point my browser at the webservice I get the test page which allows me to pass parameters to the webserive. I invoke the webservice (which does a HTTP GET according to the test page) and the webservice runs. No user and password is needed though.
What is the expected behaviour? I was hoping that the webservice wouldn't run until I supplied the admin user name and password

Mobile app based on web service data control and VO with VC runtime error

Hi,
Jdev 11.1.2.3.0 + mobile extension.
Windows 7, 64 bit.
Reproduceable with Android emulator but not on iOS and iOS emulator.
I can not test on real Android device because we do not have it in our office.
So I don't know wether this issue is related to android emulator only or to android in general.
Also not reproduceable by Oracle support.
I have a VO "Employees" with a VC "department_id = :departmentIdVariable" and exposed the find method for this VO via service interface in AM.
(see demo video from https://blogs.oracle.com/shay/entry/developing_with_oracle_adf_mobile?utm_source=dlvr.it&utm_medium=facebook).
In a ADF mobile app I create a parameter form and amx:listView like demoed in the mentioned video.
Whenever I test this app on android emulator I get the error below.
Exact the same page used in a second feature works fine.
I found out that the problem only occures on the first attept (this means when I open the page on the second feature first then this will fail and the subsequent call of the first page will be successfull).
The problem does not occure when the web service data control does not contain a method based on VC with bind variable.

Does anyone has seen the above error ?
I have recreated the model and mobile app more than 20 times, re-installed Jdev, re-created Jdev settings (integrated WLS & Co), ran the web services on a different machine.
On my site this problem is 100% reproduceable with android emulator.

Peter

Hi, Peter, this could be an issue with proxy server setting. Are you behind a firewall when you test this?
iOS simulator would use Mac's proxy setting. Android Emulator has its own proxy setup - it's a bit complicated to get to and varies based on the Android emulator you are using. For 4.1 emulator (you should always use 4.x or above emulators), you would need to go into the emulator itself, and go to settings - Wireless & Networks - click More... - Mobile Networks - Access Point Names. You should see an Access point used by the emulator to simulate network connection. Mine says "T-Mobile US". You click on it, and then you can select the proxy attribute and set it according to your office's settings.
Hope that resolves the issue.
Thanks,
Joe Huang

      checkedoutfile = ls_checkedoutfile.
and for checkin:
Dokument einchecken
CALL FUNCTION 'BAPI_DOCUMENT_CHECKIN2'
    EXPORTING
      documenttype    = pi_documenttype
      documentnumber = pi_documentnumber
      documentpart    = pi_documentpart
      documentversion = pi_documentversion
      hostname        = ''
      statusintern    = ''
   statusextern    = lf_status
      statuslog       = ''
    IMPORTING
      return          = lf_return
    TABLES
      documentfiles   = lt_files.
But it is not working cause I always get a 'communication error' from the function CV120_FTP_START_REG_SERVER when calling one of these BAPIs via web service:
IF pf_check_gui = 'X'.
    CLEAR: gf_gui_exist,
           gf_gui_checked.
    CALL FUNCTION 'RFC_PING'
         DESTINATION 'SAPGUI'
         EXCEPTIONS: communication_failure = 1 MESSAGE lf_msg_text
                     system_failure        = 2 MESSAGE lf_msg_text.
    IF sy-subrc = 0.
      gf_gui_exist = 'X'.
    ELSE.
      CLEAR gf_gui_exist.
    ENDIF.
    gf_gui_checked = 'X'.
ENDIF.
Afterwards the following function is called where I got the error 'Program no longer started via RFC. No return possible.':
-> Vault with DVA -> ** Start FTP on the client
CALL FUNCTION 'SYSTEM_START_REG_SERVER'
       EXPORTING: progname    = 'sapftp'
                  startmode   = ''                          " X
                  exclusiv    = 'Y'
                  waittime    = 500
                  startcomp   = 'C'    " G=gui, C=RFC
                  startpara   = ' '
      IMPORTING: err_code    = lf_errno
                 err_mess    = lf_error_msg
                 destination = pfx_destination.

Hi! As mentioned below I had the same problem.
There are two notes concerning security setting of the SAP Gateway:
1069911 - GW: Changes to the ACL list of the gateway (reginfo)
1480644 - gw/acl_mode versus gw/reg_no_conn_info
Your basis team should check if the Gateway settings allow external programs to register on the gateway.
Best regards

ABAP Web Service with XI and SOAP

Hi everybody!
What we are trying to implement is the following szenario:
SAP ERP HCM
SAP XI (Netweaver 2004s)
Our customers shall call a Web Service on the HCM system over the XI system transmitting 2 parameters (IDs) and get back a xml document with a list of hr related information.
This is how we started (or want to go on) with the outside-in method:
1. set up data types and message interface in XI integration repository
2. generate a proxy in HCM with the transaction SPROXY and implement the service
3. set up a communication scenario in XI integration directory using the SOAP adapter
But there are some questions left:
- how many message interfaces must be set up for the described scenario?
- is the SOAP-adapter the correct adapter for that scenario?
- how do we send back the xml information list?
- is synchronous communication correct?
- how can we test that scenario?
We are new to XI and SOA so we'd appreciate any help. thanks in advance!

how many message interfaces must be set up for the described scenario?
You would need two message interfaces. One for the outbound for the sender and one for the inbound for the receiver. There should be request and response message types for each message interface since this is a synchronous scenario.
is the SOAP-adapter the correct adapter for that scenario?
SOAP adapter is correct for the web service scenario
how do we send back the xml information list?
You will need to design the XML information list in the Integration Repository on the message interface.
how can we test that scenario?
You can use third party Soap UI Client such as SOAP UI Client or XML Spy to try calling the webservice.
