Business Process Integration using Web Services

Hi!
I'm interested to know if there are any products available today that can help a
Java developer integrate loosely coupled components into a business process. I thought
of doing this using existing Java APIs but I don't want to build all the infrastructure
myself, like translating from Java to XML and back, dealing with persistence of the
process context, correlating messages, etc.
I looked at BEA Workshop but realized it is mainly good for creating asynchronous
web services with a callback pattern but they don't address long-lived multi-step
business processes.
I've also posted my question on TheServerSide.com and was referred to Collaxa's Web
Service Orchestration Server which I'm going to evaluate shortly (http://www.theserverside.com/discussion/thread.jsp
thread_id=13413)
Thanx! Jill.

Jill,
Collaxa offers indeed a solution that reduces the complexity of integrating multiple
synchronous and asynchronous web services into a long-lived multi-step business process.
It relies on an innovative JSP-like abstraction (called ScenarioBeans).
You can download the product and kick the tires at http://www.collaxa.com
Tibco and Web Methods also offer solutions in that space.
Finally you might be able to tweak WLI using XML events to support asynchronous Cajun
style web services.
Best,
Edwin

Siebel integration using Web Service

Hi,
We are in the process of integrating Siebel with external systems using web service. We also use the Virtual business component with customer business service. After web service call, it return Siebel property set in format of XML, we need parse the XML (property set) to populate data into VBC fields in order to display data in user interface.
It seems that writing custom XML parsing script is not very desired as so many fields are involved in the integration object. We just wondering if there is any other better ways to populate data into VBC with out using escript since the integration object created by importing WSDL already listed all integration fields. Can data returned by Web service call directly populated the VBC fields through the integration object?
Thanks
Steve

Effectively what you're looking at doing here is taking your external content (from the Web Service) and then converting that into the very specific Property Set format that a VBC requires.
The EAI Data Transformation Engine is your friend here as it should let you perform the (hopefully simple) transformation between the two, although you'll also need to define the property set as an Integration Object (an External One to keep the additional envelopes created to a minimum) and then after the DTE has been called take a careful look to make sure everything is the way that it should be.
Put all these parts into a workflow itself, and use the workflow to call the external web service and that should cut to a minimum the code you'll need in the VBC.

Starting Process by Using Web Service callable object

HI,
I have created Web service CO for starting a predefined process (let call it Process2).
I am using this Web Service CO in another process i.e. Process1 (Main Process).
When execution of Process1 reaches to action where Web service CO is Attached. It's Initiating the Process2.
My Problem Is Process2 is initiated by some "Guest" User instead of processor of that action.
Plz help ASAP.

Use web service to invoke a new process execution

Hello,
I'm using BPM 10g3, and i'm trying to invoke a fully automated process via a web service
I've setup my web service http://<host>:<port>/albpmServices/<engine name>/ws/<process name>ServiceListener?wsdl
I've accessed it from a C# application i wrote and visual studio did identify my functions and such.
I can successfully start a new session (startSession(string password ,string username) and i get a sessionID back) with the web process.
but when im trying to invoke my own function (which is defined in the Process web service as a Process Execution on my beginIn parameters) I get a response with a FaultException with no visible error code.
In the BPM log I can see the folloowing lines:
1) Invoking service with id:<Process Name>ServiceListener
2) Executing item: IMMEDIATE Inst [-1, -1,-1] Act [No activity] Proc [No Process] Due 1318860646000000]
3) TransactionAction: Rollback!
while the TransactionAction: Rollback! means that something bad happened, i cant see the reason.
any idea's?

OK i've got it working.
I did all the things you suggested before but when you said i need to see that the right activity is being started i understood what's wrong
The chosen activity must be in a lane with the same role as the user login in to the session.
So i added a role on Begin and created a participent for that role, logged in with it and now it works =)
Edit: I'm the same guy that opened the threqad, just needed to make a new user for enterprise support (didn't get to use that though)

Start GP Process from VC using Web Service with parameters

Hi,
II´m trying to instantiate a GP process from a Vc iView using a Web Service; I always used Instantiation via URL but using this method I don´t have any "return" data from GP saying "Ok - The process started succesfully".
The questions are:
1) Is possible to start a GP process via Web Services through a VC Flash iview? If so, is posible to send input parameters to the process via the web service?
2) Does the web service returns any message with the status of the process? ( something like: "the process started succesfully")
Best regards,
Marco.

1) Is possible to start a GP process via Web Services through a VC Flash iview? If so, is posible to send input parameters to the process via the web service?
A: Yes. You can send input parameters to the service through WS.
2) Does the web service returns any message with the status of the process? ( something like: "the process started succesfully")
A: Yes. The return message can be added to the WS. It depends on how do designed the WS.

How to invoke a short lived process using web service start point?

I have a custom short-lived process that does not take any input parameter. I am able to successfully invoke the process from LiveCycle Workbench ES2. I want this process to be invoked by a java client through a web service call. Apart from the web service URL of my process (which looks like
http://<server>:<portno>/soap/services/MyApplication/MyProcess?wsdl&lc_version=9.0.0&versi on=1.0) do the java client know anything else? Any authentication is required?
My intention is to just find out what all the consumer of this process needs to know to invoke it through a web service call.
Was anybody able to test a short-lived process through a web service invocation from SoapUI?

I am not a programmer but I did find this article on he Developers Resource site that might lead you in th eright direction:

Hi Jill,
WebLogic Workshop provides you all the flexibility for addressing "long
lived multistep business processes" by using conversational webservices.
Multiple business processses (which could be multiple
applications/webservices's methods) invoked by a client, could be madepart
of a single conversation. All these conversations are linked by a
"conversation id", which could be generated by the client before callingthe
first method.
The Workshop webservice invoking the multiple methods would pass the
conversation id, with every request which is part of the particular
conversation. If the method is targeting an externalapplication/webservice,
that application/webservice should be able to recognise this conversation
id, and identify the "returning" client. Basically, the application should
have a way of identifying the returning client.
Please let me know if I have misunderstood the point you are trying tomake,
and your further inputs.
Look forward to your response,
Regards,

Novice Help with Creating Opportunities Using Web Services 2.0

Hello,
I recently took over our CRM integration services and was asked to push some data via our custom portal.
We use our portal to automate the creation of new opportunities in our Oracle CRM System.
The code was developed using Web Services 1.0
I was recently asked to add data to the "Parent Opportunity" field upon creation of a new Opportunity. Now I may be mistaken and if I am I will be very pleased, but it seems to me this field isn't available in 1.0
If I am mistaken and there IS a way to push data to the "parent opportunity" field using 1.0 Please completely disregard what I have typed below.
Upon looking at the WSLD for 2.0 I see "ParentoptyID" as an available field.
I took it upon myself to try and move this process over to 2.0 but I have hit a few major stumbling blocks. Here is the working code for 1.0:
Public Function CRMAddFinalShipmentOpportunity2(ByVal Session As Session, ByVal Subject As String, ByVal Type As String, ByVal Priority As String, ByVal Account As String, ByVal DueDate As String, ByVal Status As String, ByVal Description As String, ByVal AnnBudget As String, ByVal oppType As String, ByVal partNumber As String, ByVal currency As String, ByVal Territory As String, ByVal Owner As String, ByVal Opp As String) As String
Dim opportunity As nkkcrm.SiebelOpportunity20.Opportunity = New nkkcrm.SiebelOpportunity20.Opportunity
Dim input As New nkkcrm.SiebelOpportunity20.OpportunityInsert_Input
Dim results As New nkkcrm.SiebelOpportunity20.OpportunityInsert_Output
Dim strPriority As String = "1-High,2-Medium,3-Low"
Dim strType As String = "Call,Correspondence,Email,Event,Final Shipment - Book,Final Shipment - Special,Lead Follow-Up,Meeting,Opportunity Follow-Up,Other,Presentation,Quote Follow-Up,Sample Follow-Up,Service Request Follow-Up"
Dim strStatus As String = "Completed,Deferred,Waiting For Someone Else,In Progress,Not Started,Assigned,In Call"
CRMAddFinalShipmentOpportunity2 = ""
' Validate Data (CRM will validate if owner is valid)
If Owner = "" Then
AddError("Error: Missing Owner")
Exit Function
End If
If Subject = "" Then
AddError("Error: Missing Subject")
Exit Function
End If
If strType.IndexOf(Type) < 0 Then
AddError("Error: Invalid or Missing Type")
Exit Function
End If
If strStatus.IndexOf(Status) < 0 Then
AddError("Error: Invalid or Missing Status")
Exit Function
End If
If strPriority.IndexOf(Priority) < 0 Then
AddError("Error: Invalid or Missing Priority")
Exit Function
End If
If Not IsDate(DueDate) Then
AddError("Error: Invalid or Missing DueDate")
Exit Function
End If
Try
opportunity.Url = Session.GetURL()
opportunity.CookieContainer = Session.GetCookieContainer()
'Create the opportunity
Dim tmpAry(0) As nkkcrm.SiebelOpportunity20.Opportunity
input.ListOfOpportunity(0) = tmpAry
input.ListOfOpportunity.SetValue(New nkkcrm.SiebelOpportunity20.Opportunity, 0)
'Assign the opportunity Properties
input.ListOfOpportunity(0).Owner = Owner
input.ListOfOpportunity(0).OpportunityName = Subject
input.ListOfOpportunity(0).AccountName = Account
input.ListOfOpportunity(0).SalesStage = "Rebuy"

'insert the opportunity
results = opportunity.OpportunityInsert(input)

CRMAddFinalShipmentOpportunity2 = results.ListOfOpportunity(0).OpportunityId
End If
Catch webex As WebException
AddError(webex.Message)
Catch ex As Exception
AddError(ex.Message)
End Try
End Function
What changes might I need to make in order to make this function correctly using Web Services 2.0?
Currently I get the following errors- For every line of input.ListOfOpportunity(0) I get: '..cannot be indexed because it has no default property.'
Another example of an issue I'm running into is: 'SetValue' is not a member of 'nkkcrm.SiebelOpportunity20.ListOfOpportunityData'

We were able to make this work by re-modeling my code after a code sample I found that creates new Activities.
Here's my code in case it helps someone scanning these forums in the future (Disregard the Opportunity entries that are missing when you compare this to my earlier code- Those weren't relevant to making this work or not work, I simply am not using them now.):

Exposing legacy-system's service using web services

Hi everybody,
 I have questions about how web services can be used with legacy system.
Let�s say I have a server serving stock data. The server is just POJO, it isn�t web module, doesn�t run on any J2EE container and client will request for data using my proprietary API which run over TCP/IP. My question is that what is the best practice or widely used pattern for exposing my stock service through web services.
 I�m not a web service expert so I think the easiest patter may be using web services as an adapter for my API. I�ll use jax-rpc to create web services StockWS.war and deploy it on a web server running on the same machine with my stock server. The web services will, in turn, internally use my proprietary API to request data.
I can see 2 problems in the above approach.
1. The need of web server. Administrator needs to start 2 processes; stock server and the web server containing StockWS.war. It would be great if I can get everything work in one process. Is there any framework or API that my stock server can internally use to intercept soap request over HTTP so that I don�t need a web server and everything is encapsulated in one process?
2. Performance. There will be my API sit between web services runtime layer and my stock server which may cause performance issue. If I can find a framework I�ve mentioned in problem1 then I can get rid of the API layer.
Please ignore my grammar mistakes.
Any suggestion is welcome, and if you have experiences integrating web services with your legacy system, feel free to share it here.
Thanks in advance.

Why should I use Web Services?

I am managing an Internet project for my company. We exhaustively use IIS, ASP and SQL 2000 Server and until today we feel very comfortable with those tools. We successfully developed some COMs also to make additional work. As a personal interest in my free time I am learning Java. I began two months ago and using certain APIs downloaded from the net I could develope applications and applets for an SMS messaging system interacting with a real cellular phone provider. I also had to learn about RMI and implement it in this project. That system now is working nice. So I was encouraged to learn more about Java and I found the Web Services world. Everybody is talking about it(and .NET of course), in the net, in magazines etc.. So, I decided to learn about Web Services.
I read these paragraphs at the beginning of the Web Services Tutorial:
"In a typical Web services scenario, a business application sends a request to a service at a given URL using the SOAP protocol over HTTP. The service receives the request, processes it, and returns a response. An often-cited example of a Web service is that of a stock quote service, in which the request asks for the current price of a specified stock, and the response gives the stock price. This is one of the simplest forms of a Web service in that the request is filled almost immediately, with the request and response being parts of the same method call."
Maybe I am not able to understand the concept but this is more or less what I get using for example an ASP or an RMI or a Servlet, don't I?. Ok, there is no SOAP involved in those methods mentioned but still I have a request, and response and so on. So, what is the advantage I will get working with a Web Service?. Can anybody explain me?
Regards,

Here are a few reasons why. Enjoy!!

What Can Amazon Web Services Be Used For?
Although Amazon Web Services is a cool technology, it also provides the very useful function of enabling business partners to interact with Web site through standard protocols. This interaction can lead to a deeper, more valuable relationship for parties involved. Here are a few of the ways that partners are benefiting from Web Services:
Associates: Associates program enables Web sites to link to Amazon.com and earn referral fees for sales that they drive through their links. Many Associates are now using Web Services to build more effective links to our store, thus enhancing their sites and earning more money.
Sellers and Vendors: Amazon.com has thousands of third-party sellers who offer their products on our Web site. Using Web Services, these sellers can more easily manage large quantities of inventory on our platform, and download the latest product information to make sure that their products are competitively priced.
Developers: Among the thousands of developers who have signed up to our Web Services program, many are now creating solutions to help other people work with Amazon. These solutions are powered using our Web Services APIs.

Q: General : When will you use Web Service as opposed to just Servlet and/or EJB?

Hi,
I don't know if this is an appropriate question to ask for this class as it's not
workshop
specific. I was wondering how will I decide when it is appropriate to use a web
service as opposed to say servlet or an EJB for my application? What is a good
rationale to use?
Thanks,
Sadhana

Hi Adam,
Thanks a lot for giving such a lucid explanation of my vague question!
I understand now the difference between when to use EJBs/Servlets/Web Services.
Thanks again!
Sadhana
"Adam FitzGerald" <[email protected]> wrote:

Hi Sadhana,
Web service versus Servlet versus EJB. Which one to use? That is a very
good question.
EJBs should be the core desription and processing of your business rules.
They generally
have good performance, are easy to integrate into your security set up but
they require
access using the RMI-IIOP protocol. This means that generally EJBs are not
accessible
outside of your firewall and their clients have to be written in Java (other
enterprise
objects or applets or GUI applications).
Servlets often form a web-based front end to EJBs. They also have good performance,
integrate into security and only require HTTP access. This means they are
accessible
outside your firewall and any client with a HTTP or web API can call on
them, however,
there is no standard contract or rules for this type of interaction so you
will need
provide direct input into development of the client.
Web services are also accessible via HTTP and so can be accessed from outside
your
firewall. In fact, Web services internally within Workshop and WebLogic
actually
operate by using servlets and EJBs but the main advantage is that the mechanism/contract
for interacting with the web service is a well defined standard (WSDL) and
can actually
be registered or retreived dynamically (UDDI). Since web service standards
are open,
most popular programming languages already provide client APIs to interact
with them
thus freeing the web service developer from direct interaction with the
client developer
and letting the client be developed on any platform. The penalty for this
openness
is a small performance hit (XML translation) and a slowly maturing security
model.
So in summary, use EJBs for business operations that have Java clients within
your
enterprise, use servlets to provide web style access to your business operations
(like web pages) and use web services to enable automated clients that can
be written
on any platform either inside or outside your enterprise (firewall). In
fact, it
is common to write the EJB first and then to expose some parts of it outside
of your
enterprise by writing a web service wrapper (maybe using the EJB controls
that we
saw in class).
I hope this helps.

How to get the list of values for a dynamic parameter using Web Services SDK?

I am struggling to get the list of values for a dynamic parameter of a report.I am using Java Web Services SDK ... I tried to use PromptInfo.getLOV().getValues() method but it does not work.First of all ... is this possible (to get the list of values for a dynamic param) using Web Services?Second of all, if this is possible, how should I do it ... it seems it works fine when running the report from CMC. It asks for DB logon info and after that it provides a list of values.Thx 

Your assumption is correct. We are trying to get the LOVs from the Crystal Report. I was not aware that this is not supported by Web Services SDK.We used Web Services SDK to integrated the Crystal Reports in our web application. We implemented some basic actions for reports: schedule, view instances, run ad-hoc reports.We encountered this problem when trying to run/schedule reports with dynamic parameters (a list of values from DB). We were unable to get the LOVs.Please let me know if you can think of an alternative to look at.Thanks a lot,Catalin

Performance impact of using Web Services?

As BEA and other vendors continue to add Web Services support
to their enterprise software, what is your plan for
quantifying the performance impact and the functional
correctness of using web services before going live with the
final application?
Empirix is hosting a free one hour web event discussion on
web services testing and automated web services testing
solutions on Thursday, January 17, 2-3pm Eastern time.
To sign-up for this web event or learn about other web
events being offering by Empirix this month, go to:
http://webevents.empirix.com
For your convenience, here is the complete abstract:
The advent of web services has brought the promises of
integrating multiple software applications from
heterogeneous networks and for exchanging information
from vendor-to-vendor or vendor-to-consumer in a
standardized way.
As web service technologies are deployed within and across
organizations over the next several years, it will be
critical that web services undergo performance testing.
As with any enterprise software project, the adoption of
proper test methodologies and use of testing tools will
play a key part in the overall success or failure of
projects utilizing web services. In a compressed
software project schedule, an organization must
quickly determine if its web services will operate
successfully under a variety of load conditions. Like other
web-based technologies, successful web services will need
to respond quickly and correctly when implemented.
During our presentation, we will discuss the testing
challenges created by this emerging technology, along with
the variety of testing solutions available. Automated
web service testing will be discussed and demonstrated
using FirstACT, the first web services performance testing solution available
on the market. Using a sample web
service, automatic test case creation, scalability testing,
and results analysis will be explored.

As web service technologies are deployed within and across
organizations over the next several years, it will be
critical that web services undergo performance testing.
As with any enterprise software project, the adoption of
proper test methodologies and use of testing tools will
play a key part in the overall success or failure of
projects utilizing web services. In a compressed
software project schedule, an organization must
quickly determine if its web services will operate
successfully under a variety of load conditions. Like other
web-based technologies, successful web services will need
to respond quickly and correctly when implemented.
During our presentation, we will discuss the testing
challenges created by this emerging technology, along with
the variety of testing solutions available. Automated
web service testing will be discussed and demonstrated
using FirstACT, the first web services performance testing solution available
on the market. Using a sample web
service, automatic test case creation, scalability testing,
and results analysis will be explored.

What is the best way to deploy application that uses web services?

Hi all,
I'm having some problems figuring out the best way to deploy our app now that we've switched over to using web services.
I'm fairly new to Java and web services. From what I understand, JNLP and WebStart are methods to deploy Java clients to users and not for creating war files and the like.
Here's a little background:
We have a large PowerBuilder/Oracle application. The db consists of over 500 tables and the client consists of several thousand PB components. A user creates "transactions" which contain a series of "sub-transactions" within. Most of the data is collected and stored locally in the client in a series of datastores. When the "finalize" happens, the records are validated and sent to the database.
We are in the process of moving each of the subtransactions (currently in the PB client) into subPROCESSES on a java project. We are using the JAX-WS framework to develop the web services in Netbeans. These web services aren't much more than remote xml as the messaging technology. For writing data back to the database, we are using the Java Persistence API to function outside of an EJB container but will shortly be migrating to the Glassfish application server to use several of the EJB container frameworks including the EntityManager.
We haven't attempted any type of deployment and are unsure of where to start. Any suggestions would be so helpful and appreciated!
Thanks!

It is for launching rich client GUI based (AWT, Swing, SWT..) applications onto the end-user's desktop.
There are some parts of JWS that might seem peripherally useful to the installation of a web-app., but it is really not a 'good fit'.

OutofMemory Error while sending file to database using Web services

I have a file of 30MB to be written to the MySQL database. I am doing this in Axis web services and it gives me the following error:
(I am using Tomcat as the application server and Apache as the web server, Axis 1.3 and MySQL standard 5.0.21 version. I have set the minimum and maximum heap size and it works well without using the web service (just uploading and downloading from the database using a simple java program). Another thing to notice is that I can send a file of almost 10MB size to the database using web service without any problem. But it doesn't work with the 30 MB .)

Sorry for the delayed response here, forget to add it to my watchlist. I didn't catch if you were using Java 1.5 or not. Prior to 1.5 the default maximum heap space was 64MB which with the overhead of the appserver might be your problem.
Take a look at http://java.sun.com/j2se/1.5.0/docs/guide/vm/gc-ergonomics.html and the java -Xmx <size> command line option to change the default (I believe the size argument is in bytes, but don't hold me to that). I think you can pass that as a command line option to the startup script, but you should check the doco to see if it needs to be wrapped in some other arg etc.,
I seem to recall running into this same problem a few years back when I had a servlet doing some intense graphics processing on the fly and setting this option fixed the problem.
