Part 1 discusses about the problems and the corresponding solutions to attain the

How to Simply Convert SDO to DOM Element and Vice-versa

2011-08-03T18:18:00.001+03:00

In previous post, I demonstrated how to marshall POJOs to SDO. In this post, I will show how to convert SDOs to DOM Elements without parsing them to or from String. The key is the following methods from the commonj.sdo.helper.XSDHelper: void save(XMLDocument xmlDocument, javax.xml.transform.Result outputResult, java.lang.Object options); -- wherein, we can instantiate a DOM node and wrap it

POJO TO SDO Marshalling through JAXBHelperContext

2011-08-01T18:05:00.001+03:00

In previous post, I demonstrated, how to easily convert pojo's to xml elements and vice-versa thru JAXB. The key to implementation in that post was the JAXBContext object which served as the factory for the Marshaller and Unmarshalller objects which accordingly takes charge for the marshalling and unmarshalling of POJO's to XML. In this post, I will take a step further by demostrating POJO to

Sample JAXB Application Converting POJO to XML Element and Vice-versa

2011-07-31T23:33:00.004+03:00

In developing SOA applications, it is necessary that you have tools in converting Java objects to XML and vice-versa. In Oracle Human Task Services for example, the task payloads are represented as XML elements, and if there's a need to manipulate those payload then, I believe that its better to do the manipulation on a Java instance equivalent, rather than navigating to the complex tree

Custom BPM Workspace Deployed in a Non-SOA Server in a Different Domain

2011-07-28T14:04:00.007+03:00

In my previous post, I demonstrated through a sample application how to utilize the reusable task flows from BPM Workspace. In this post, I will share the steps and configuration to deploy the custom application to a non-soa server located in a different domain. The soa server in my case is a stand alone installation of Oracle SOA Suite with configured domain "base_domain" that supports SOA,

Custom ADF UIShell Application with Oracle BPM Workspace Task Flows

2011-07-27T00:04:00.001+03:00

An Excerpt from Appendix A (Creating Custom ADF Applications with Oracle Business Process Management Workspace Task Flows) of the Oracle Fusion Middleware User's Guide for Oracle Business Process Management 11g Release 1 (11.1.1.5.0) Different features available in Process Workspace are exposed as standalone reusable components, called task flows. You can embed task flows in any Oracle

How to Send Notification to the Initiator of a BPM Process Instance Upon Completion of an Activity

2011-07-23T23:18:00.020+03:00

In BPEL, human workflow is almost always expected to be represented by a single human task activity with multiple steps - that is why the Oracle SOA Suite 11g Human Task component has a lot of facility for notification related to the raise of events like the assign, error, expire, withdraw, alert, complete, and etc. on a particular task definition. But in the current release of BPM (11.1.1.5), it

Custom BPM Applications(InitiableTasks) ADF TaskFlow

2011-07-21T12:05:00.003+03:00

In a previous post, we show how to access the initiable tasks in a main method of a simple Java class. In line with, this post demonstrates how to get the task's URL and launch the corresponding generated BPM task details form in an ADF application. The following are the key methods and artifacts: getTaskDisplayURL() - this method retrieves from a task object, the URL defined in the runtime

Bug: Boolean Accessors Prefixed with "is" not recognized as attribute in JDeveloper 11.1.1.4

2011-02-26T15:25:00.002+03:00

The biggest fail that I noticed in JDeveloper 11.1.1.4.0 (aka Patch Set 3) is the inability to recognized boolean properties that are prefixed with "is" like isActive() as property in the entity xml files. My disappointment is that- this is properly recognized in earlier releases. We wanted to jive with the most recent release, so we have a lot of refactoring to make. Below is a sample entity

ADF Region as Source of Partial Trigger

2010-10-27T11:57:00.002+03:00

In my previous post, I describe a way on how to expose the state represented by the pageFlowScope object of a bounded task flow (BTF) to the outside world. Now, if there's an event inside the BTF that changes it exposed state, then the dependent outside component needs to refresh as well, and the idea is for it to have a partialTriggers property that point to the region where the BTF resides.

Bounded Task Flows as Components with Exposed State or Attributes

2010-10-26T15:26:00.011+03:00

Overview Bounded Task Flows (BTFs) can be considered a breakthrough in again bringing the concept of web component reuse to a new level. BTFs can be package into ADF Library JAR files and placed into to a reusable component repository, in which they can be applied in multiple projects and/or applications. This document describes a way on how to make BTFs a more full-pledged interactive

Using GMail as Mail Server for Oracle SOA Suite 11g Notifications

2010-10-08T22:54:00.004+03:00

Lucas Jellema has a good post about configuring SOA Suite 11g for sending email notifications with Google Mail, but unluckily, as he also noted, it was not working anymore. Nevertheless, that post demonstrated that Gmail could work as SMTP server for Oracle SOA and inspired me to dig more. In this post, I will share my configuration and the steps that I have made to have a working GMail SMTP

SDO: Implementing a HashMap like Service Data Objects

2010-09-30T03:45:00.004+03:00

Introduction I envisioned to create a Generic ADF Human Task Form to support all of our human task (workflow) activities, and in the solution that I thought of, I need an SDO HashMap. For those who are not familiar, the ADF Human Task Form are remotely deployed bounded task flows (BTFs) that are being accessed by the Oracle BPM woklist app in showing the details of a listed task. The remotely

SDO: Wrapping Simple Types as DataObjects

2010-09-13T11:44:00.002+03:00

The SDO specs specifies that an XSD element with type "anyType" is map to a DataObject SDO type. This means that you cannot assign simple types like String, Integer, Long, and Boolean among others into this element, because if you do so, you will receive a java.lang.ClassCastException in runtime. To be able to do that therefore,

ADF Faces RC: Generic Query and ListOfValues Model for EJBs

2010-09-01T19:35:00.174+03:00

Overview The and components of ADF Faces RC are a must-have for applications, but if you are not using ADF Business Components, then you face the challenge of implementing your own query and listOfValues models. This pattern provides an implemented reusable model that you can readily adapt to your enterprise needs when you are using EJBs. Problem Description

Loosely Coupled Bounded Task Flows + Outside-world Messenger

2010-08-12T14:05:00.006+03:00

Chris Muir posted in ADF UI Patterns forum a thread entitled "Overcoming a challenge: combining UI Shell dirty tab + self-closing-BTFs". That post enforces my realization that there is something wrong with my current implementation of bounded task flows, in which we have so much dependency on the TabContext object of the UI Shell. This dependency made me unable to reuse the same task flow inside

ADF UI Shell: Updating Title of the Current Tab

2010-07-29T13:21:00.002+03:00

Sometimes you may wish to update the current tab title after some actions like saving a new record. You can do so through the following code inside your backing bean: public void updateCurrentTabTitle(String title) { TabContext tabContext = TabContext.getCurrentInstance(); int currentTabIndex = tabContext.getSelectedTabIndex(); Tab tab = tabContext.getTabs().get(

Configuring a New Oracle SOA Domain on Oracle Enterprise Linux

2010-06-21T11:26:00.002+03:00

Introduction With the current trend of having 64 bit as the new desktop standard, then you would most likely come into a situation where you have a hard time deciding what OS to buy that can support your software development tasks, while not being left behind. That OS selection decision is made simpler by the advent of Virtualization wherein you can have multiple OS on a single hardware

ADF Security: SQLAuthenticator is Simply the Best!

2010-04-09T01:44:00.011+03:00

When choosing authentication repositories, something that is more familiar can be the best choice. And what is that "something familiar" for us developers?- Of course, the relational database (unless, if you know LDAPs more :D). Relational databases (RDMS) has encryption capability while authentication providers supports cryptographic hashing, so what else could you ask? Plus the recommendation

To accomplish the creation of a dynamic menu based on user roles, we need to do

Java: Comparing BigDecimal objects for equality

2010-02-10T16:36:00.009+03:00

If you are developing a financial application you would probably agree that 1.0 is equivalent to 1.00, but the BigDecimal API says otherwise. If you will run the following code, you will be bewildered at first on the results: package blogspot.soadev.test; import java.math.BigDecimal; public class BigDecimalTestRunner { public static void main(String[] args) { BigDecimal x = new

JSR 303 Bean Validation: @ValidateDateRange - A reusable constraint annotation to validate date ranges

2010-01-29T03:47:00.008+03:00

In a previous blog-post, I have described my experience on JSR 303 Bean Validation, and in the process, this @ValidateDateRange constraint annotation came upon into my mind. I thought that it would be useful so it inspired me to create its implementation and eventually made this blog-post. The @ValidateDateRange is a class-level constraint annotation that will validate a date range represented

Oracle XE: Exporting and Importing Dump Files

2010-01-28T03:03:00.009+03:00

An easy way to copy a schema would be through JDeveloper Database Copy Utility under Tools>Database>Database Copy... menu. But in our case, we encounter errors in the transfer of records from the source to my target connection and many of the records were not exported successfully. This is the reason why we resorted to exporting and importing dump files. Yesterday, I was given a dump file which

JSR 303 Bean Validation: @AssertMethodAsTrue - A reusable constraint annotation that spans multiple properties.

2010-01-26T11:36:00.018+03:00

I have made my own hands-on on this Bean Validation based on the [hibernate-validator-4.0.0.Beta2] and the experience was great. One thing that I have observed though is that there is no built-in annotation to check for a constraint spanning multiple properties, or to check if a certain property is valid based on other properties. One obvious example to this is validating date ranges where you

2009-12-25T10:09:00.018+03:00

If you have a requirement to conditionally display a tab, a link, or a toolbar button to prevent navigation to a protected page allowed only for some specific roles then I bet that the following security expression will satisfy your need: 1)#{securityContext.regionViewable['your.page.targetPageDef']} Chris Muir has a nice blog about conditionally displaying the global tabs of the ADF UI Shell

2009-12-25T00:55:00.019+03:00

The discussion below is taken from my feedback on the ADF UI Patterns in OTN forum, I just copied it here for my reference: Hi! I have already figured out how to pass parameters to my bounded taskflow that I intend to launch on a separate tab.

Error Running "populateImages" Ant Target of the Oracle FOD Infratructure Application

2009-07-13T09:16:00.002+03:00

I wonder why my FusionOrderDemo StoreFrontModule user interface do not display the product images. I re-run the MasterBuildScript build.xml of the Infrastructure application bundled in the FusionOrderDemo_R1 and noted that the populateImages target raises an exception and that is another "timezone region not found error".

Error Deploying to Stand Alone WebLogic Server -"java.lang.ClassNotFoundException: oracle.adf.library.webapp.ResourceServlet", "Deployment incomplete"

2009-07-11T18:05:00.000+03:00

To avoid the following error :"java.lang.ClassNotFoundException: oracle.adf.library.webapp.ResourceServlet", deploy the application on the application context and not only on the UI project. To avoid the "Deployment Incomplete" error, try to disable proxy settings. To avoid more errors in deploying the Fusion Order Demo to a stand alone WebLogic Server 11g , refer to the following tutorial:

How the ADF PageLifeCycle come into the picture in ADF 11g?

2009-06-17T21:34:00.000+03:00
