Using UDDI to create reusable ESB/BPEL artifacts

I would like to make my ESB artifacts reusable by removing end-point details from ESB configuration and having that kind of detail in an UDDI. It does not seem that the ESB has the ability to do UDDI inquiry's in runtime. Does anyone now of a work around? Have played around with the endpoint properties beta feature in Jdev to achieve some sort of abstraction, but this is not good enough (http://download-east.oracle.com/docs/cd/B31017_01/integrate.1013/b28211/adapter_services.htm#CHDJJDHB)
From BPEL there seems to be a way of at least using UDDI service keys (http://www.oracle.com/technology/tech/soa/soa-suite-best-practices/reusable-soa.html).
Any input would be much appreciated.

Hi
We're planning an enhancement that will enable ESB to query UDDI for service endpoints using the uddiServiceKey, similar to what we provide with BPEL.
If you send me an email on this subject I'll inform you when the enhancement is available.
Thanks

Dynamic lookup using UDDI inside of BPEL

Currently I'm looking into using UDDI as a solution to finding web services for BPEL, as opposed to simply keeping static WSDLs around. Initially I would just like to know if it is possible to do a lookup to a UDDI server inside of BPEL, and then invoke a service returned by the lookup.
The ideal solution we are looking for is to keep a local WSDL to one of the web services we would like to call. We would first attempt to call this web service... but on the event of a failure (such as the service being down), we could go to UDDI to find another instance of this service that is up and running.
This leaves a lot of questions though... how possible is it for BPEL to work dynamically in the first place? MUST I specify the location of the Web Service at compile time? Is it possible to keep a local directory with WSDLs in it, and have BPEL parse them at run time (meaning, I could invoke some function inside of BPEL to parse the WSDL to find the address to the web service)?
Is this solution even remotely do-able?
The other solution which seemed more feasible would be to create a proxy service, which basically mimics the input/output behavior of the original web service I want to invoke, but in reality is using UDDI to find the real web service, and forward the results to/from it.
I'm wondering why UDDI is generally so overlooked. It seems like it's a buzzword to get into your product, but nobody anywhere seems to make any actual usage out of it. It seems like a pretty important idea behind the SOA structure.

I think the challenge is in figuring out when to do the request for search to the backend. If you have fast turnaround time, you can probably send a new request each time the user types a character and bring back the results for it as they type - that may be overkill though. if this is the way you do it, then your filtering is done before it returns from the server. For performance reasons, you may wish to use a stored procedure in the database that does a regular expression search on your data ( only search the columns you have to.)
As for getting the data back: In the result handler, the function you specify [in the remote method call] to load the returned data into the local dataprovider, you could simply have it clear the dataprovider re-populate it and call refresh() on the dataprovider each time. I am not sure how that would appear to the user as it again depends on turnaround time from the backend, size of the dataset, etc.
I hope this gives you an idea at least. Without knowing more about your application and how it is architected, it is difficult to provide any "reasonable" recommendation. It is an interresting problem and one that sounds like fun to solve - of course, I am not sitting there with management breathing down my neck either.

How to use own created WebService in BPEL?

Hello!
I have a problem using an own created Web Service (a wsdl file) in BPEL Process Manager.
At the moment I have a Java program which is getting values from SAP via SAPJConnector. From this Java program I generate an WebService File (wsdl) via Axis (on my local Tomcat Server).
Now I want to use this own created WebService (wsdl file) in BPEL. I don't know how to bulid it to my BPEL Server so that I can use it in JDeveloper.
Does anyone know what I have to do?
Would be nice if someone could help me, because its very important
Thank you

Hi.
Thanks for your reply.
The way to invoke the WebService in BPEL Designer is not the problem i have.
The problem i have is how to deploy my own created WebService (from a Java class with AXIS) to the BPEL server (OC4J).
Do you know a solution for this?
I described my Problem detailed in another thread "Thread: Issues Publishing Web Service to OJ4J"
Tanks and Regards

Is it possible to use Application Adapters with out having ESB, BPEL

Hi,
Is it possible to build and use application and DB adapters with out having ESB, BPEL in the project. We need to have Oracle E-business suite adapters in our application but we don't want to purchase ESB and BPEL.
Is there any workaround possible or i need to go for ESB and BPEL.
Thanks,
Amit Kumar

Hi,
Application adapters and technology adapters are delivered with Oracle's SOA Suite. It can be used with BPEL, ESB, BAM or other products with SOA Suite.
In theory, the JCA adapters can be accessed through JAVA CCI calls. Hence, any J2EE application can invoke the adapter. But, you will have to find from Oracle whether they provide support for such a access. Application adapters such as MySAP, Siebel, PeopleSoft and JDEdwards supports invocations only through BPEL and ESB. They do not support any other invocations such as JAVA CCI calls.

Error in creating reusable worklist regions

Hi,
I tried to create reusable worklist region for the Task List task flow(taskList-task-flow-definition) in my fusion application using the following reference:
http://docs.oracle.com/cd/E14571_01/integration.1111/e10224/bp_worklist.htm#BHADHGCF
I have passed the following parameters to the taskList-task-flow-definition task flow:
federatedMode=true
showServerColumn=true
The wf_client_config.xml is present in the WEB-INF folder and src folder. Its contents are:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

</workflowServicesClientConfiguration>
I have deployed the app to the Weblogic Admin Server. (The SOA Managed Server is present in the same domain). I'm getting the following Error message:
Error showing tasklist. Possible reasons could be : 1. SOA server connection information is not available. 2. If it is run in federated mode, the default server may be down.
Any solution to this?
Thank you,
Rashmi

I was able to solve this by creating a bean with a method that returns the WorkflowServicesClientConfigurationType Object.
Reference: Section A.7 in http://docs.oracle.com/cd/E17904_01/user.1111/e15175/bpmug_ws_taskflows.htm#autoId27
This works when the JSPX which contains the taskflow binding is a 'Blank Page' and I'm able to see the tasks.
However, I tried to follow the same steps on a JSPX which uses 'UIShell template' and got a NoClassDefFound error for oracle.bpel.services.workflow.client.config.WorkflowServicesClientConfigurationType
Any solution to this?
Thanks.

Error creating a new BPEL domain in a 2 server environment with common DS

I want to create two new BPEL domains, one for production and one for test env
instead of using the default domain.
There are two application servers with BPEL PM (10.1.2.0.2) using the same
Dehydration Store. Active-Active mode, no cluster.
A new BPEL domain is created successfully with BPEL Admin Console in server A.
The problem is the server B knows nothing about the new domain. I cannot select
the new domain on BPEL Console login page on server B.
When I tried to create the same domain in server B the following error
occured:
Exception
Operation failed because:
Error updating domain index.
An exception occurred while writing the domain index (id"szolinfo", ref "1") to
the datastore; the exception reported is: ORA-00001: unique constraint
(ORABPEL.DOM_PK) violated
Please check that:
+ the machine hosting the datasource is physically connected to the
network.
+ the connection pool properties as defined in the application server
startup properties are valid.
+ the database schema for the OraBPEL server has been installed in the
datasource.
This is because the two servers are using the same database.
The new domain require a new folder and a lot of files also inside the domains
folder on server A and B. On server A this is created by BPEL Admin Console.
How to create the same domain in server B?
Are there any scripts/tools to use for this reason?

These steps on Server B resolved the problem:
1: cp -r domains/default domains/<new-domain-name>
2. cd domain/<new-domain-name>/config
3. Edit the following files by replacing the string 'default' with the name of your
new created domain in the following
elements/attributes:
archive-config.xml: <value>/home/mla/app/bpel101202/integration/orabpel/domains/de
fault/archive</value>
domain.xml: <bpel-domain-descriptor version="2.0.6" id="default">
4: In the case that the password for the domain is different compared to the default domain, the file 'auth.properties' has
to be copied over from the server where the domain was created.
5. Restart the BPEL PM

How to get the service name of a webservice using UDDI API

Hi,
Iam working on setting up a dynamic partner link in a BPEL, by passing the endpoint of a web service queried from the UDDI (Oracle Service Registry 10.3 ) using the API. Iam able to do it successfully.
Now, for example I have two operations in my wsdl, one to createCustomer and the other to bookTicket. I need to get the operation name using UDDI API so that i can pass it along with the endpoint to the partner link. ie. When i need to createCustomer, my UDDI API code will need to get the service name createCustomer and the endpoint and I would pass them to the partnerlink and the createCustomer operation of my webservice would be called.
Can any one help me to get the service names of the wsdl using UDDI APIs.
Thanks,
Ananth

JDeveloper - ESB / BPEL - JMS Adapter - prefix queue name with db schema

When I use the JMS Adapter in ESB to create a new message queue producer or consume using database (AQ) I'm experiencing a problem when selecting the queue.
I can browse the queue in the database but when I have selected the queue JDeveloper prefix it with the schema name owning the queue.
Example:
java:comp/resource/DocumentQueueResourceProvider/Queues/QUEUES.DOCUMENT_IMPORT_QUEUE
Schema owner is QUEUES and the name of the queue is DOCUMENT_IMPORT_QUEUE.
The problem is when I try to use it its unable to look up the queue and I have to manually remove the prefix from .wsdl file before deploying it - as with setting mcf.IsTransacted='false'.
When the resource provider finds the queue and exposes it in the JNDI three it does it without the prefix.
Question: How do I either:
a) make the schema prefix be removed by JDeveloper
b) make the resource provider prefix the queue name with the schema name.
Anybody?
Best regards
Christian Damsgaard

How to use the validations and exceptions in BPEL

Hi,
How to use the validations and exceptions in BPEL.
pls provide one sample example to give the exceptions and validations in BPEL

Hi,
For example you can create a simple BPEL Process and you can throw an error during running process. If input data is not valid and format is not correct you can throw error using throw activity and using catch activity you can catch particular error. The catch-all will handle all the error occurred with the scope.
you can also refer faulthandling section in the link for more information related to exception handling.

Also.. Here are the details of BPEL create domain screen..
Create New BPEL Domain
BPEL Domain is a logical grouping of processes, instances and activities. A domain may be accessed either by the domain or administrative password.
Domain Id: <<Nattest>>
Each domain requires access to a JDBC datasource to store instances and activities. Tx Datasource JNDI must refer to a datasource with JTA support. Datasource JNDI may refer to any datasource (JTA not required).
Datasource JNDI: <<<<JUST took default..>>>
Tx Datasource JNDI: <<JUST took default>>>

I've seen this if the database is down or in a funky state. Try shutting down BPEL, and restart the database, then bring BPEL back up. If you're using Oracle Lite just use the "Stop SOA Suite" GUI from the Start Menu.

I am using Search Service WSDL in my bpel to execute the saved search in IPM, but how do i map my input type variable to the search argument of that Search Service.

Please Suggest!

How do I create reusable titles in premier elements 13?

how do I create reusable titles in premier elements 13?

thomas
Premiere Elements 13/13.1 Expert workspace
After you create your title in the Titler, close the Titler.
The tilte file will have been automatically placed on the Timeline at the position of the Timeline Indicator.
Open Project Assets, and select the thumbnail for the title file that was placed there also automatically.
With the Project Assets title thumbnail selected, go to File Menu/Export/Title in order to export your title as a prtl file saved to the computer hard drive for future use. This principle also applied to Title Templates edited in the Titler.
Please let me know if you are OK with the details. Please ask if you need clarification on the above.
Thank you.

HTTP GET/POST method support in ESB/BPEL

hi,
I want to call HTTP URL using GET/POST method from ESB or BPEL. Can you please tell me how this can be achieved?
Thanks,
Vaibhav

how would you direct the GET requests to one servlet and the POST requests to the other?
Wouldn't they need to pass thru' yet another servlet to decide which is which (GET or POST), and redirect them accordingly?
I would have both GET and POST handled by the same single-point-of-entry servlet. For example, not all data is sent to the server via a POST - you can send form data via a GET, using name/value pairs in the url.

Creating ReUsable TaskFlows

I'm using ADF BC, JDev 11G. I need to reuse the task flows built as a part of different applications. I've included the sources by opening the respective projects(model and ViewController). Following the instructions from Packaging a Reusable ADF Component into an ADF Library I was able to create the File System.
The error is that I'm not able to use that taskflow as a button on the page in a different application. I'm getting error MDS-00013. How to solve this issue.
Is there a simpler method to create reusable components, task flow etc.

Hi,
Once you create a file system connection to the directory where you have deployed your ADF Library, you can expand the library in the Resource palette. You can right click it to add it to an active project in your app. If you have multiple projects, choose one that you wanna add the library to.
If you have reusable task flows you will find ADF Taskflows node under the jar in the resource palette. Just drag and drop the task flow as a region or a dynamic region in your jspx page. Or if you wanna use it as a task flow call or return, then you can see the jar in the component palette. Just expand the drop down in the component palette, choose the jar. Then drag and drop the task flow.
BTW if you have a db connection etc packaged in your jar an dif you are reusing them, then the password wont be included. Expand the app resources accordion, choose your connection and enter the password for your db connection.
Thanks.
