Dynamic partnerlinks using a wrapped wsdl

Hi all,
My current situation is as follows:
Im using a webservice which doesn't define partnerlinks and as a result I've created a new wsdl which wraps the original webservice. In the wrapping wsdl I've defined the missing partnerlink. In the bpel.xml I reference the wrapping wsdl and not the wrapped wsdl. The result is that I have a webservice which includes a partnerlink def. - so far everything is fine.
The wrapping wsdl is shown below:
<definitions
name="CCSSecurityServiceRemote"
targetNamespace="http://com.scandihealth.ccs.webservices.security.common/CCSSecurityServiceRemote.wsdl"
xmlns="http://schemas.xmlsoap.org/wsdl/"
xmlns:tns="http://com.scandihealth.ccs.webservices.security.common/CCSSecurityServiceRemote.wsdl"
xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
xmlns:plnk="http://schemas.xmlsoap.org/ws/2003/05/partner-link/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
>

<import namespace="http://com.scandihealth.ccs.webservices.security.common/CCSSecurityServiceRemote.wsdl"
location="http://becks:8002/ccswebservices/CCSSecurityService?wsdl"/>
<plnk:partnerLinkType name="CCSSecurityServiceRemotePortType_PL">
<plnk:role name="CCSSecurityServiceRemotePortType_Role">
<plnk:portType name="tns:CCSSecurityServiceRemotePortType"/>
</plnk:role>
</plnk:partnerLinkType>
</definitions>
My problem is the location attribute which is hardcoded! I would like to be able to define it as a preference in the bpel.xml file but how can I achive that? I've been looking at dynamic partnerlink, which seemed to be the tool to solve my problem but I can get it right.
Any clues?
Best regards and good weekend to you all!

Since you also make use of the wrapper wsdl for the dynamic partnerlink..maybe this can help you :
http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html
<variable name="partnerReference" element="wsa:EndpointReference"/>
with this you're able to assign the endpoint dynamically.

Dynamic Partnerlink to ESB dbAdapter service

I have many stored procedures (around 40!) to call from a BPEL process. To handle errors coming back from these (sqlerrm) and the associated human interaction to suspend then resume the process, I have the partnerlink call inside a double loop. I don't want to repeat this 40 times, and also may want to be able to reconfigure the calls (execution order, exclude/add some etc.). So far to achieve this, I've created and tested the double loop, created a dbAdapter to get the endpoints from a db table, and am now trying to get dynamic partner linking to work with this. Each service call is registered in the ESB as a dbAdapter and exposed as an invokable service (not via a routing service). I can successfully call each of these individually.
I've read Carey's cookbook article in detail (great article!) and got it working nicely with a plain ol' web service and am able to loop through the dbAdapter results to get the endpoint addresses. Now I'm having trouble getting it to work with one of these ESB-exposed dbAdapters. I've tried using the concrete WSDL from the ESB in the dynamic partnerlink - but even though I can dynamically assign the endpoint at runtime, it seems to ignore this and always calls the same service. I've then spent many frustrating hours trying to create a WSDL template from the ESB concrete WSDL to import into my process at design-time - so far to no avail.
I notice that the WSDL for these ESB-exposed dbAdapters is about "3 levels deep" that is they each import another WSDL or schema including one for the dbAdapter itself. Even though I think the db interaction should not be exposed outside of the ESB (to the caller) - only the "front" of the service should be.
Am I completely on the wrong track here? or will more perseverance pay off and I will get it working? Has anyone successfully done this? please help...

I figured that in bpel 2.0 EndpointReference element needs to be wrapped in a <service-ref> element BPEL 2.0 Dynamic Partnerlink mismatchedAssignmentFailure error . However it requires it to be static configuration.
How can I make it dynamic to get set the address from a variable ?
Please help.

Unable to get the response from dynamic partnerlink

Hi
I used dynamic partnerlink, in this i am able to invoke the services dynamcially but i am unable to get the response from the services which i had invoked dynamically. In my dynamic partnerlink wsdl i had included callback binding and call back service in the wsdl you can see them below
<binding name="LoanServiceCallbackBinding" type="tns:LoanServiceCallback">
<soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
<operation name="onResult">

please help me on this

Hi, thanks for the input
Actually My partnerLink had two messageTypes one for Input message request and the other for the Output message request and for the input message i had used the operation as initiate also for the output messsage type operation as result.For both of them binding is defined.
With these am passing the values from myBPELl to the service which am nvoking dynamically but unable to capture the response the variables are local to myBPEL.

Are dynamic partnerlinks really dynamic

I am trying to develop dynamic partnerlinks for my BPEL process. As I understand, if I want to call one out of n number of partnerlinks say service1,service2,service3 at runtime, all having the same interface, i have to know atleast the names of these n services at designtime so that i can make an entry into the wsdl file.
Now suppose, i want to add another service (Service 4 ) with same interface , I still have to modify the wsdl file and redeploy the process.
Is there any way by which, i dont need to modify the wsdl file/redeploy the process.
Ideally i would like to maintain the name and url of all the services, externally to BPEL say a DB table or configuration file and based on my input to BPEL process would read from this configuration and call the partner service so that as and when the number of services grows, i dont need to redeploy the BPEL process.
is this achievable ?

I have been trying to get this to work with my processes.
However the examples given in BPEL sample/references/Dynamic Partner link and http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html are using a LoanService.wsdl to create the partnerlink to which they later assign the endpoint references.
But none of the document says, how to create this LoanService.wsdl or how it is arrived at.
I have three bpel processes service1,service2,service3 having the same input schema. So their wsdl's service1.wsdl,service2.wsdl and service3.wsdl are same except the endpoint address.
Now I have another BPEL process CallXXService which will be calling either of the three services based on some input. My problem is how to create something similar to LoanService.wsdl which I can use to create the partnerlink.The three wsdl's for these services(service1.wsdl,service2.wsdl,service3.wsdl) are totally different in structure to the given LoanService.wsdl.
Any idea/suggestions please ?

Dynamic partnerlink binding problem

I am trying to create a dynamic partnerlink as in http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html .
When I am trying to create this with LoanService.wsdl, it works correctly for me but when I try to create it for my own service, it is showing up some errors which I fail to understand.
I have three services service1,service2,service3.
I have created another web service called CallPartnerService in which I have imported the service.wsdl to create the partnerlink. After that I am following the instructions in the cookbook to create the create the partner reference variable, copy the partnerReference variable into the Service partner link etc
However, when I run it, I get the following error on invoking the partner service.
Cannot find binding operation.

Dynamic Partnerlink with WSIF HTTP Binding

Hi,
I have been trying to change the endpoint location details of my HTTP Binding Partnerlink during runtime / deploy-time. AFAIK, there are two ways to do this.
1. Deployment Descriptor : Change the "location" property in bpel.xml to point to a different location. Ideally this can be done at deployment using ant or use the Java APIs to change them during runtime. This works for partnerlinks which use a SOAP Binding, but does not work for HTTP Get/Post Bindings.
2. Using WS-Addressing : Again this works with a SOAP WSDL, but no go with HTTP GET/POST WSDLs.
Has anybody been able to get dynamic partnerlinks working for non SOAP Partnerlinks?

Dynamic partnerlink example

Hello,
I am quite new to Oracle BPEL Process Manager. I was reading about the dynamic partnerlink and I checked the example. What I want to learn is: Do I need a separate wsdl file for the dynamic partnerlink as LoanService.wsdl in the example? If I want to make calls to public web services, do I have to write that wsdl file myself?
When I searched the forum I found this: ' As a workaround you can try dynamic partnerlink but your partnerlinks should be defined at design time. For details please refer to sample "orabpel\samples\references\DynamicPartnerLink" '.
Does it mean that I have to define the addresses of the web services that I might call during the execution of the process, at design time (in a separate wsdl)?
Thank you in advance.

Hi 55555 55555,
I'm not sure that I understand what you mean. It is true that you need to have a WSDL file in advance. But this WSDL file is necessary mainly to be able to define the port types and the SOAP binding information. The URLs of the services that your process uses at runtime do not necessarily need to be match those that you put in the element "service" of the WSDL file. Concretely, if you look at the file "Supplier.wsdl" in:
http://sky.fit.qut.edu.au/~dumas/ServiceInteractionPatterns/BPELCode/OneToManySendReceive-Dynamic.zip
You will see that there are three "service" declarations:
<service name="Supplier1">
<port name="SupplierServiceP" binding="tns:SupplierServiceBinding">
<soap:address location="http://localhost:9700/orabpel/default/Supplier1"/>
</port>
</service>
<service name="Supplier2">
<port name="SupplierServiceP" binding="tns:SupplierServiceBinding">
<soap:address location="http://localhost:9700/orabpel/default/Supplier2"/>
</port>
</service>
<service name="Supplier3">
<port name="SupplierServiceP" binding="tns:SupplierServiceBinding">
<soap:address location="http://localhost:9700/orabpel/default/Supplier3"/>
</port>
</service>
These "service" elements are important, because they define the service names (i.e. "Supplier1", "Supplier2", and "Supplier3" in this example). However, the URLs that you put here ARE NOT IMPORTANT if you're doing dynamic addressing in the BPEL code. These URLs are only used by the BPEL engine if you're not doing dynamic addressing. Indeed, try replacing these lines in the WSDL file with the following ones:
<service name="Supplier1">
<port name="SupplierServiceP" binding="tns:SupplierServiceBinding">
<soap:address location="http://www.dummy.com"/>
</port>
</service>
<service name="Supplier2">
<port name="SupplierServiceP" binding="tns:SupplierServiceBinding">
<soap:address location="http://www.dummy.com"/>
</port>
</service>
<service name="Supplier3">
<port name="SupplierServiceP" binding="tns:SupplierServiceBinding">
<soap:address location="http://www.dummy.com"/>
</port>
</service>
And then try running again the process OneToManySendReceive.bpel. You will notice that it works! This is because in the process OneToManySendReceive.bpel, the addresses of the services Supplier1, Supplier2 and Supplier3 are determined by the "assign" statement between lines 74 through 83 of OneToManySendReceive.bpel. Thus, you can put "dummy" addresses in the "location" element of your WSDL file(s). Note that you do need to define the "service" and "location" elements in your WSDL file and it is important that the service names that you use in the BPEL code match the service names in the WSDL files (but the choice of these names is up to you and it doesn't matter if this is the actual name of the process that you're calling!). Importantly, the URLs that you use in the BPEL file and those that you use in the WSDL file do not need to match, and this allows you to achieve "dynamic addressing". Just try out the OneToManySendReceive.bpel process and you'll see.
If you wish, I can send you the whole Oracle BPEL project for the OneToManySendReceive. Please contact me at my e-mail (m.dumas at qut.edu.au). And for more information about what this process does, see http://www.serviceinteraction.com

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

<p>I am struggling to get the list of values for a dynamic parameter of a report.</p><p>I am using Java Web Services SDK ... I tried to use PromptInfo.getLOV().getValues() method but it does not work.</p><p>First of all ... is this possible (to get the list of values for a dynamic param) using Web Services?</p><p>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.</p><p>Thx </p>

<p>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.</p><p>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.</p><p>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.</p><p>Please let me know if you can think of an alternative to look at.</p><p>Thanks a lot,</p><p>Catalin </p>

How to create a viewobject dynamically without using wizard

Hi,
I am Using jDEV 11G, i need to create a viewobject dynamically without using wizard, without binding from any entity.
Actually my intention is to make a grid like in .Net, when a user want to create a new row in RichTable without using DB.
just like shopping cart.
i have done thsi code:
ViewObjectImpl view=new ViewObjectImpl();
view.addDynamicAttributeWithType("Att1","String",null);
view.addDynamicAttributeWithType("Att2","String",null);
view.addDynamicAttributeWithType("Att2","String",null);
Row rw=view.createRow();
rw.setAttribute("Att1","First1");
rw.setAttribute("Att2","First2");
rw.setAttribute("Att2","First3");
view.insertRow(rw);
I have a RichTable , i need bind this viewobject into that.

Error While creating ABAP Consumer Service using Provider service WSDL.

HI Friends,
We are trying to consume service from Provider service.
Provider service is developed on CE 7.11-NWDS7.11 and published in CE7.11 registry.(used outside in method and implemented in EJB/Deployed/Published/tested) sounds good.
We are trying to consume in ABAP (ECC 6.0 EHP4 SPS16).
when we are trying to create service consumer from se80 selected url : provider WSDL picked up from from Service registry.
At the end of wizard its throwing error.
error description.
Message Policy in Name space "http://schemas.xmlsoap.org/ws/2004/09/policy " is not unique in WSDL.
Unable to generate proxy.
Any pointers to resolve this.
Regards
Chandra

I would suggest to test the service in XML Spy using the same WSDL or the URL of the WSDL. If XML Zpy throws the same error, there could be some problem in the provider service generation itself..!!

Question regarding the creation of a custom dynamic stamp using "Will Print" from "Set Doc. Actions

Hi all,
Using Acrobat 9.0 Professional, I have successfully created a dynamic stamp using the forums where I have added Login / Date to my own image and it works great as designed. However, the problem I am having is that when a document is stamped it becomes flat and doesn't update dynamically which does not work for my requirements.
I need to create a pdf that is stamped by myself so that other users (using only Reader) can open the pdf and when printed the stamp will print with the correct date/time (in the format I describe below).
I found a workaround (outside of a stamp) where I added a text box (called "Today") that updates everytime the document is printed by going to
Advanced / Document Processing / Set Document Actions / Document Will Print
and adding the following Java Code:
var f = this.getField("Today");
f.value = util.printd('yyyymmddhMMss', new Date());
This provides me with the unique number that I need for printing (ie: 20100317102030). It works great as an inserted text field on my pdf.
My problem is that when I use the "create custom stamp" as in other tutorials by inserting this new text field, it will not update (or display) on print, even though it was set the exact same way as the custom stamp I got working using the Adobe dynamic stamp information.
Can you offer any advice on how I can get this to work as a custom stamp? I would rather not have to create both a stamp and then overlay the text field manually as I have hundreds of documents (maybe more) to do this for.
Also, as an aside, if I could get this to work, I would also like to add Login ID that updates in the same manner as my custom date format (but one problem at a time I guess! )
Thanks for any and all help that you can provide. I looked through these forums and elsewhere, but I don't seem to see anyone else with the same problems (with solutions posted).
I really wish Adobe had a Custom Stamp creator as part of their program, with the dynamic option. It would be so easy for them and save a lot of users so much time.

Stamps are just like a inked rubber stamp, except in Acrobat you can suppress printing them and you can move them. So if you use a dated "Faxed" stamp when you fax a document, even though you can adjust the stamp before affixing the stamp, once the document is stamped the date on the document can not be changed or moved. It appears, that the use of a stamp might not be the best solution.
"Interactive" means Acrobat JavaScript programing.
With JavaScript not only can you insert variable data but also fixed text strings or a combination of both.
So your script could be updated to something like:
var f = this.getField("Today");
f.value = "Printed : " + util.printd('yyyymmddhMMss', new Date());
http://forums.adobe.com/message/1333261#1333261
Getting the 'login name" will require some special JavaScript code being added to an application level JavaScript folder that runs upon initialization and is the data or function created is then accessed by your PDF. This file will need to be installed on each user's system.

With a PDF Dynamic form using show/hide actions, how to ensure that when the completed form is saved, closed and re-opened, the form still show the fields as before it was closed?
I have developed a form with fields hidden by default, that become visible based on box ticked or radio button selections.

How to create a dynamic newsflash using dreamweaver and PHP

Hi there,
I would like to create a dynamic newsflash using dreamweaver and PHP in that the newsflash will be pulling information from a MySQL database. The newsflash should also have a link to view more information about the piece of news a user wants to know more about. Which tools do I need to use in dreamweaver and how's the procedure to go about that. Any advice is highly appreciated. Thanx in advance!

I think you´ll need at least a MySQL table with the following columns:
- id (primary key, int, auto_increment etc)
- news_headline (varchar)
- news_teaser (text)
- news_content (text)
What I´d personally add are columns such as:
- news_date (date or datetime)
- news_external_link (varchar), if a "read more..." link is supposed to navigate to an external URL rather than displaying the contens of the "news_contents" column.
Based on such a MySQL table it should be easy to use Dreamweavers standard Server Behaviors to create the usual datalist.php, insert.php, update.php and delete.php documents, and there are numerous tutorials out there which will teach you how to do that.
Am I right when assuming that you´ll also need to know how to automatically pull, say, the 5 most recent news records from the database ?

How to create two level dynamic list using JSP , Java Script and Oracle

I am new in JSP. And i am facing problem in creating two level dynamic list using JSP ,Java Script where the listdata will come from Oracle 10g express edition database. Is there any easy way in JSP that is available on in ASP.NET.
Plz response with details.

1) Learn JDBC API [http://java.sun.com/docs/books/tutorial/jdbc/index.html].
2) Create DAO class which contains JDBC code and do all SQL queries and returns or takes ID's or DTO objects.
3) Learn Servlet API [http://java.sun.com/javaee/5/docs/tutorial/doc/].
4) Create Servlet class which calls the DAO class, gets the list of DTO's as result, puts it as a request attribute and forwards the request to a JSP page.
5) Learn JSP and JSTL [http://java.sun.com/javaee/5/docs/tutorial/doc/]. Also learn HTML if you even don't know it.
6) Create JSP page which uses the JSTL c:forEach tag to access the list of DTO's and iterate over it and prints a HTML list out.
You don't need Javascript for this.
