Open ESB Question On Web Services

I have been reading about Open ESB and it seems it might be the tool that I am looking for to solve a specific set of problems.
Given a WSDL file and a URL to a web service, can I expose the service to be accessed by different protocols? From what I read, if there exists a binding component for that protocol, then I should be able to hit the external web service using that protocol. Are there any examples of doing this using regular web service messages (the trivial case), as well as examples using other protocols? Is BPEL a requirement for this type of exchange or is it much simpler?

Question concerning Web Service Deployment

I have a question on web service deployment as it pertains to multi-client SAP systems.
I created and deployed a web service in the client that is used for the development of client-independent objects. There are no issues when calling the web service following deployment.
I am trying to use the same web service on the same SAP system, but on a different client. What is the proper way for accomplishing this? As of right now, the only way I've been able to do this is to open up the desired client and deploy the service again. I tried to take a transport and copy it to the other client using SCC1, but it failed since all the objects referred to client-independent objects.
Below is the URL of the WSDL that was generated via SOAMANAGER.
http://svr-sap05-dev.xxx.com:8010/sap/bc/srt/wsdl/bndg_DF2B9EDC2EA40CF1A9B7001CC4459012/wsdl11/allinone/ws_policy/document?sap-client=120
Client 120 is the client used for development and is where the web service was created and deployed. I would like to use the same web service, but in a different client.
I tried in changing the logon parameters of the web service using SICF, but the invocation failed. It only works if the client mentioned in the logon data matches the client specified in the URL.
I am assuming that SAP builds the namespace of the web service using the client specified in the above URL. If this is the case, then I will have no choice but to deploy this service manually in the other client.
Is something wrong being done or do I have to do the same deployment in the other client?
Regards,
Vince Castello

In Netweaver 7.01 (with SOAMANAGER) you can no longer deploy webservices via STMS.
You have to login in each client and create endpoints in each one.
It's a pain, but SAP says it's too risky to implement the solution via STMS or something like that.
There is a SAP note about this.

Authomatic task periodically opened using Connect-IT web services

Hi all,
I have a question about Connect-It web service connector.
We have change requests such as giving someone temporary local admin authority, usb usage etc. Since this authority must be taken back in a certain time, we thought that there should be an authomatic task periodically opened when the times come.
For example, if I give an authority to someone for USB usage authority for two weeks upon a change request, then I need an automatic change task to take back this authority after two weeks.
According to this, can we create an automatic task with Connect-IT using HP Service Manager change web services and how should we create a scenario? Also is it possible to make a task periodically opened with Connect-IT web services without using any scheduler program
Thanks in advance,
Best regards.

So, in reality, this issue has nothing at all to do with "it was working; now it is not", because you've destroyed all of the evidence that would exist in a "was working; now is not" scenario. What we really have here is a NEW installation that has failed.
So, from the perspective of a NEW installation that is not working...
Are there any other roles, features, services, or applications installed on this server?
Did you install the Web Server Role exactly as described in the documentation?
Did you install the WSUS Role exactly as described in the documentation?
Were there any other roles, features, services, or applications installed onto this server
after your original (working) installation of WSUS?

Oh, well, I have red and followed the documentation exactly step-by-step on the technet library, and I can guarantee you nothing went wrong because this is not my first installation for it
When I told you about the old damaged installation and the new installation which is also failed and showed me the same symptoms as the old one, I was sure that nothing wrong with the WSUS itself, but rather it is something wrong with the environment
Answering to your above questions, the answer for all is that: that server is only used for WSUS, nothing more
Anyway, I have managed to restore the service thanks to your previous reply where you point to the CONFIG folder inside the NET framework folder, I checked the files in there, some were changed to the date I think has stopped the service, so I repaired the
NET framework 2, and restarted
It is working fine now and syncing with the update server

Aqualogic ESB Capabilities beyond web services ?

I'm new to Aqualogic 2.0 ESB and I'm exploring integration posibilities and scenarios where it will be useful.
I have some questions regarding limitations and interoperability with other:
- is there an overlap between ALSB 2.0 and WebLogic Integration?
- Is posible to integrate something like a back end system using CICS (ECI) and a client using web services via AquaLogic ? if so, How ?
- How can I use the underlying capabilities of the underlying WebLogic 9.0 server (i.e J2EE Connectors, jdbc pools, etc) from Aqualogic ?
- Can I publish an EJB remote interface running in another app. server as a "service" in Aqualogic 2.0
thanx in advance

I've only gone as far as reading high-level information and seeing some demos, but I think I can answer some of this.
Concerning the difference between ALSB and WLI, it's expected that WLI could be used to build a service that would be an ALSB endpoint. ALSB is a "no coding" interface. You simply define endpoints, transports, and routing rules. WLI is a development platform.
I'm not sure how to interpret the CICS question. Does your client have a web service invocation API? If so, then you could integrate that with ALSB.
To sort of answer the last two questions with a summary, if you can provide a web compatible interface to a component, then you can integrate it with ALSB. That interface could a web service or JMS. Depending on what version of things you're using, you can automatically provide a web service interface to an EJB session bean.

ESB and Secured Web Service strange response

Hi guys,
We are facing strange response from ESB when we try to talk to a Secured Siebel service. Credentials are passed useing SOAP header, and in test case of not including any header at all.
1-First try will return error, bad user name password
2-Second or third try may even return actually results from Siebel service (and header is not included at all). I tested using SOAPUI tool.
3-But If I test Siebel Service directly things go fine.
Question: Is there some thing like a caching of SOAP header in ESB, if not an idea on how can after giving first fault second try right after that returns query results (from siebel service).
any helps apperciated.
thanks

there shouldn't much difference in the time for the response ..., also when you are calling the secured web service from another BPEL, make sure you don't consider the time of the calling process ( i mean that BPEL ). you just try calling the secured web service from the EM console if it is a SOA composite. do you see any messages in the log files ? the procedure you followed is correct only, confirm here., i have posted a similar solution long back..

Questions on web services in the CRM system from abap

Hi, we are new to consuming web services within the abap engine and have a couple of questions
When we consume the webservice do we have access to the web.xml and ejb-jar.xml deployment descriptors is there a standard servicref element
Are these descriptors editable so we can add JAX/RPC client side messages to the service ref element
What are all the versions also as I can't seem to find any info also any documentation on the above if it exists would be greatly appreciated
Cheers,
Devlin

Hi Devlin,
When you can consume the services with CAF core or deployable proxies within Netweaver04s, you are able to see the web.xml and the ejb-jar.xml deployment descriptors.
For Comsuming services within ABAP,this doc shoukd serve the purpose,
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/6066fbe8-edc4-2910-9584-a9601649747d
This doc shows how to provide and conmsume services in ABAP,

Also I found an old doc which talks about consuming in Netwaever,probably throws somelight on deployable proxies.

Questions about web services and BPEL in ALBPM

Hi all,
We are currently evaluating various BPM products in order to decide which one to use. Currently I am evaluating ALBPM Studio 5.7 and I am running my processes on the embedded engine provided with the studio. I have some questions:
1. We want to be able to use complex types for the web services that are generated for processes. Will this limitation be solved any time in the future?
2. We want to be able to use the generated web services directly (that is, without calling the startSession method first). Is that possible?
3. I could not find extensive documentation about developing BPEL processes. There is only one small chapter in the developer documentation about BPEL processes. Is there any more documentation or sample about how BPEL is used in ALBPM?
4. I have developed a very simple BPEL process, but when I try to deploy it, I get the error "Activity BPEL receive does not have any incoming transitions". How can I resolve this issue? I guess it may be a problem about my PartnerLink definition.
5. When I try to catalog a wsdl which imports another wsdl (and when the imported wsdl also imports some xsds from another namespace), I get an error which says that a web service xxx with namespace yyy is not found, but actually the thing named xxx is not a web service but a soap fault. What could be the problem?
6. Is it possible to write a BP method in PBL for a BPEL activity?
Thanks in advance and best regards..

ESB and Stateful web services

Folks,
I’ve got two web services that are called in succession. The first web service performs a search and caches the results on the server, returning only some basic information about how many results were found (in the payload) and a session id (as an attribute in a HTTP header). The second service is called afterwards, passing some page request information (in payload) and the session id (in the HTTP header). The session id is used to find the appropriate search results and return them lazily (based the given page request information).
The web service requests are done through ESB and OWSM. My problem, however, is that according to the ESB developer’s guide (http://download-west.oracle.com/docs/cd/B31017_01/integrate.1013/b28211.pdf , page 5-29, ‘Limitations of ESB Header Support’) ESB is not capable of setting header attributes (at least not SOAP header attributes).
Is it possible to use stateful web services with the ESB? If so, how is the SessionID handled on the ESB and how is it correlated with the clients of the ESB who are getting the results back from this stateful web service?
Thanks in advance,
Joseph

Dave,
We have invoked the two services mentioned above in four different manners using Java code.
1. We are invoking the services through ESB with no success. The HTTP header (set-cookie) never makes it back.
2. We are invoking the services through Web Services Manager (the services are registered directly with OWSM) with no success. The HTTP header (set-cookie) never makes it back.
3. We are invoking the services through Web Services Manager (with ESB providing a wrapper for the services) with no success. The HTTP header never (set-cookie) makes it back.
4. Invoking the services directly (no OWSM, no ESB). This method is successful. HTTP headers are being exchanged without incident.
We are using Ethereal to check out the traffic going back and forth so we can see the SOAP headers getting propagated back and forth as you had mentioned. The problem is that the HTTP headers (as mentioned in my first posting) containing the session information are getting dropped when using ESB or Web Services Manager.
Any suggestions?
Thanks,
Joseph

Some question about Web service

Hi experts,
I have created a Web service about Function Module 'BAPI_EXCHANGERATE_GETDETAIL'.Now I plan to use Transaction code 'WSADMIN' to create a WSDL.But the display result of IE tell me my host could not be resolved by DNS.I don't know how to solve this question, and which happened based on this question.Is there any experienced experts tell me the solution?
Thanks & Best regards!
Kelvin

Hi,
In your system folder:
C:\WINDOWS\system32\drivers\etc there is a file hosts;
Add your server I address and servername in it.
like:
193.10.100.70 myserver.com MYSERVER
Hope this will resolve the problem. If you do not have authorisation for the same, your network admin will help.

Question about web service client

Hi,
I am creating the a client to call non wls web serveice.
First I need to create the client jar using clientgen. My question is when i create the client jar I need the wsdl file. where is the correct place to store the wsdl file? Also I have development and production wsdl file with the different service location. Do I have to store both of the wsdl files? It's a trouble to remember to build the different client jar for development and production (using different wsdl), is there anyway that I can build the client jar once and somehow dynamically configure to use different wsdl (ie service location) in different environment? Thanks

Hi Holy,
If you know the WSDL hasn't changed since you used it when running the clientgen Ant task, you can just use the one that is inside the JAR that clientgen produces. To do this, you just need to not specify an argument to the XXX_Impl constructor. For instance:
AttachmentPartsService_Impl service = new AttachmentPartsService_Impl();
This has some performance benefits, because it reduces the total number of network calls, the client-side Web Services stack makes. If you specify the URL for the WSDL to the constructor (as recommended by someone else here), the client-side Web Services stack will issue an HTTP GET to get it. Now if the WSDL that is returned uses types that are different than the ones the clientgen Ant task generated classes for (i.e. the ones in the JAR generated by the clientgen Ant task), you are in trouble because the client-side Web Services doesn't generate serialization/deserialization classes (i.e. the ones in the JAR generated by the clientgen Ant task) "on-the-fly".
The service endpoint for a Web Service call can (and should) be set programmatically, from a properties or configuration file. This will look something like this in the code:
import java.util.Properties;
import javax.xml.rpc.Stub;
private static Properties loadProperties(String fileName) throws IOException
if (fileName == null || fileName.length() == 0) return null;
Properties props = new Properties();
FileInputStream fis = null;
try
fis = new FileInputStream(fileName);
props.load(fis);
finally
if (fis != null) try { fis.close(); } catch (Exception ignore){}
return props;
public static void main() throws Exception
Properties props = loadProperties("MyProperties.properties");
Client client = new Client(props);
public Client(Properties properties)
AttachmentPartsService_Impl service = new AttachmentPartsService_Impl();
AttachmentPartsServiceSoap port = service.getAttachmentPartsServiceSoap();
if (schemeHostPort == null) schemeHostPort = "http://localhost:7001";
((AttachmentPartsServiceSoap_Stub)port)._setProperty(
Stub.ENDPOINT_ADDRESS_PROPERTY,
properties.getProperty("production.AttachmentPartsService.serviceEndpointURL"));
This way, you can have a different properties file for each environment you propagate the web service to, as opposed to saving copies of WSDL files just to have the "correct" service endpoint address. It also has the additional benefit of letting you store the service endpoint URLs for more than just one web service.

Mike Wooten

Questions about web services

Hi! Experts:
I am at the Web Servivces Navigator.
I have a basic question about it:
We are using MI7.1 which has NO Java stack. Therefore we do NOT have the Web Services Navigator.
How do we use the Web Services for MI7.1?
Thanks!

Hi!
1) SICF lists the BSP services; Web Services are requests between java application to client application.
Are you sure them are the same thing?
2) When I compare the services between web service navigator and SICF, I do not see there is any
relationship. For example, if I search "AdapterMessageMonitoring" in SICF, I cannot find it.
I think SICF and web service navigator are listing totally different services.
Therefore my question is that since MI7.1 has NO Java stack (hence NO web service navigator ), how
are web services handled in MI7.1?
Thanks!

A question regarding Web Service Client

Hi,
I read the tutorial "Creating Web Service Clients with JAX-RPC" and I coundn't understand something.
The code conatins, for example: (Stub) (new MyHelloService_Impl().getHelloIFPort()); Since it's a stand alone client, how it suppose to recognize MyHelloService_Impl()? Should it be added to the project libraries? What did I miss here?
Thanks, Lior

The wscompile tool generates class files required by the static stub client. The HelloClient program creates a stub as follows:
stub = (HelloIF_Stub)
(new HelloWorldService_Impl().getHelloIFPort());
The wscompile tool generates the HelloIF_Stub and HelloWorldService_Impl classes and places them in the build/classes/server/ subdirectory. To construct the HelloIF_Stub name, wscompile appends _Stub to the portType name defined in the WSDL file:
<portType name="HelloIF">
To create the HelloWorldService_Impl name, wscompile appends _Impl to the service name, which the WSDL file specifies as follows:
<service name="HelloWorldService">

JDeveloper 10g 10.1.3 Web Service Question: java web service calls another

I am looking for what I think should be a simple example/tutorial but so far no luck. I am using JDeveloper 10g 10.1.3 and the Oracle Application Server.
I want to do this:
- create a simple Java web service
- deploy it
- create another simple Java web service, that makes a call to a method on the first service
- deploy it
client->WSfront->WSback
I want to keep this as basic as possible.
Although I have found examples of how to create a web service proxy, there are no examples that I have found that show how to use that proxy in another web service:
I did what I thought were the right things; generated a proxy for the first web service, and used that proxy in the second web service's source Java class. However when I deployed and tested many classes were missing: all the classes the proxy class depends on.
I actually managed to get something like this working but had to manually create the .ear and .war files for WSfront, explode the archives, and manually add the missing classes to its WEB-INF/classes.
I am comparing this to things like Weblogic Workshop in which doing this exercise is a snap.
Is there a simple graphical way to do this in JDeveloper?

Hello again,
I am quite surprised I got no responses to my query below.
Can anyone explain how I might do this?

Basic question about Web Services

First I wan't to say that i've searched the net for info, and all I could find was some advanced code snipets. However, I would like to start from the begining.
I'm trying to develop a web service which takes XML as input parameter, an returns some other XML.
I developed a WS like that
import org.w3c.dom.Element
public static Element returnElement(Element xml)
{ return xml }Now here's the problem:
I would like to be able to call this WS from other programming languages, like Delphi, C++...
To try and make something like that, I converted xml to String and pass it to a WS. However, this string is too big (about 3200 chars) for HTTP GET to handle.
How can I do that?? Which classes to use? How to represent data in XML form that could be read in Java and other programming languages?
Please, at least, post a link, I just need some basic pointers.
Code examples would be much apreciated.
Thanks a lot in advance,
Good day,
Simon

A basic question about web service

Hello,
Does all the Web services need to be run under a Web server?
Or it just needs to be run under a server which has either a web container or a J2EE container?
I mean if the application does not need to generate HTML pages, but just generate SOAP messages, do I still need to have a web server?
Thanks!

A J2EE server runs independently and does not require an HTML/HTTP web server.
If you're just interested in SOAP, an application server or servlet engine which understands the SOAP specification will be enough.
