0 0 It is not always easy to troubleshoot ADF performance problems – it is often complicated. Many parts needs to be measured, analyzed and considered. While looking for performance problems at the usual suspects (ADF application, database, network), the real problem can also be found in the often overlooked browser load […]
0 0 Not all Oracle ADF projects are built with ADF Business Components (ADF BC). Some organizations prefer to use EJB/JPA (EclipseLink) instead of ADF BC. The EclipseLink JPA provides developers with a standards based Object-Relational persistence solution. The application still reflects the Model-View-Controller architecture. In this case the model is provided by […]
0 0 Recently we added a great new feature to the ADF Performance Monitor: network and browser load time information. Now you know exactly every end-user experience of your ADF application, in real-time. You can quickly resolve any performance bottlenecks with this end-to-end visibility. You can even drill down into an individual user to […]
0 0 Last week I presented at the UKOUG’14 conference on creating intuitive & interactive dashboards with the ADF Data Visualization Components. Frequently end-users are overwhelmed with too much and confusing information displayed in rows and columns. It can be difficult to quickly get the relative significance. This session discussed how to create intuitive, interactive […]
0 0 Last week I presented at the UKOUG’14 conference on instrumenting, analyzing, & tuning the performance of Oracle ADF applications. Instrumentation refers to an ability to monitor or measure the level of a product’s performance, to diagnose errors and to write trace information. Instrumenting gives visibility and insight of what is happening inside the […]
0 0 Recently I was implementing the ADF Performance Monitor at a customer site and doing a detailed performance analysis. This customer had severe (and less severe) performance problems but was unable to pinpoint the exact pain points. Frequently, end-users were complaining because they were experiencing first a very good performance (response times […]
0 0 ADF BC ViewObjects provide a very valuable mechanism to page through large data sets so that a user can navigate to a specific page in the results. Range Paging fetches and caches only the current page of rows in the ViewObject row cache (at the cost of another query execution) […]
0 0 In a series of blog articles I show how you can instrument your ADF Application key actions. Instrumenting gives visibility and insight of what is happening inside the ADF application and in the ADF framework (what methods and queries are executed, when and how often).

0 0 In this blog I will show you how you can call a webservice programmatically in Java without using a webservice library like JAX-WS or Apache Axis. Normally you would use of course a webservice library, but in some cases this can be useful and quick; for example when you have […]
0 0 In our current webservice project with JAX-WS in JDeveloper 11.1.1.3 we have a challenge with calling a webservice. This webservice from a remote organisation does not accept specific SOAP header elements our client application creates – although we followed the contract of the WSDL correctly. Of course this webservice must […]
0 0 This step-by-step starter hands-on provides an example how to make a JAX-WS webservice proxy in JDeveloper, and save retrieved data from this webservice in a batch-job to your own database with ADF Business Components.

0 0 In our current ADF10g project we have many refresh issues. After an insert or update some view object attribute values are not shown. Many attributes of our entity based view objects get their value from the SQL statement that queries the data of the view object (SQL-calculated attribute). After an […]
0 0 In a proper and user-friendly application, it is a good idea to let your user know when his session has expired. Or to inform him that his session is about to be expired. How can you accomplish that in an ADF10g? In this article I will first show you how […]
0 0 Breadcrumbs are a navigation technique used in many applications, and its popularity grows. Its purpose is to give users a way to keep track of their location. Breadcrumbs typically appear horizontally across the top of a webpage, usually below any title bars or headers. They provide links back to a […]
0 0 As you can imagine, with many validators on many entity objects you will end up with equally many generated message bundles. When you start localizing the error messages, that means you have to maintain many classes. Keeping those messages consistent can become an error-prone task. In this article I will […]
0 0 Growing insight during development of a project often results in a wish to rename a BC object (entity object, view object, association, view object attribute, alias, usage, etc.) in JDeveloper. Or in JHeadstart to rename objects like a group, item or a region. Often, developers are not renaming objects because it is […]
