Sometimes work can also be play – and guess what, that’s good for the worker and for the work. Read this new article about how work and play intersect in the research conducted by the Oracle Applications User Experience (OAUX) group’s emerging technologies team, the AppsLab. For more from the AppsLab and what they’re researching, visit their blog. Two recent series of posts were on the developer experience and fun with Facebook. CONFERENCE SEASONThe OAUX team’s on-site lab...

If you would like to boost ADF UI performance, you should look into client side validation and formatting options possible to be done in ADF UI. Today I will describe how you can implement client side converter, to format number value on client side, without making request to the server. Same approach could be used to implement client side validators. You can raise error message and it will be assigned to UI field in the same way, just like any standard ADF error message....

Oracle Business Activity Monitoring (BAM) 12c comes with Oracle SOA Suite and BPM, and it is a very powerful tool that should be used on most projects.  Organizations are using it successfully today to graphically visualize trends in their data to make operational decisions and to send alerts before issues occur. One of the difficulties organizations initially have after installing Oracle BAM 12c is determining how to define the security levels and permissions for its...

Vue.js is a popular framework for developing rich client web applications, leveraging browsers for all they are worth. Vue.js has attracted a large number of developers that together have produced a large number of quite interesting reusable components. ADF Faces is itself a quite mature framework for the development of rich web applications. It was born over 10 years ago. It has evolved over the years and adopted quite a few browser enhancements over the years. However, ADF...

This post (next in the BAM series) is about BAM Alerts. Alerts were not part of the POC, but in the blog series I also wanted to pay attention to it, resulting in this post. I have made a very small example to get some feeling in there and will not get into all the details of alerts. As usual, first a piece of theory from the Oracle documentation: An alert performs one or more actions when launched by an event and filtered by one or more conditions. An event can be an...

One of the biggest advantages of Oracle JET is, that we have a toolkit instead of a framework. This means, we are easily able to add third party libraries into our stack. When you take a look at all those javascript libraries out there, you will realize that the pain is to choose the right library for the right purpose. With version 2.2 you had to rely on bower to add components or libraries. Now in version 3 everything is about NPM. In my opinion it is great that they...

Part 1 - Create a WebLogic JNDI Database Connection This explains how the WebLogic JNDI connection to a database schema is created.  In the next two posts, you will see how the Database Adapter can use this connection once it has been created.  This simply describes the steps that are necessary to configure the JNDI connection initially.  Components exposed in a SOA application can be exposed as a service, and a call to the database is no exception.  In order to invoke the...

I have received feedback from users working with JET UI - sometimes it is not obvious that action button was pressed, users tend to press same button again very fast, which leads to parallel REST calls executing at the same time. In JET - REST call is executed asynchronously, this makes user to believe action was done instantly when button was pressed. However, REST call still may run in the background - while user will be trying to call same service again. While in most of...
