In a series of blog articles I will 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). These runtime diagnostics can be very effective in identifying and solving performance issues. This enables developers to diagnose and solve performance problems at an early stage and to build an (more...)
This week in the BPM Adaptive Case Management workshop at the Oracle Fusion Middleware Community Forum I ran into a strange bug.
The background: earlier this week my own laptop broke down. So I had to borrow a laptop, what fortunately I could borrow from one of the presenters (thanks Guido). The thing is, though, that it runs on Ubuntu 12, so I ran my VM in VirtualBox 4.3 on Ubunty. Now actually that (more...)
In web development, a lot of times you want to avoid your browser caching messing up different sessions. Luckily most browser have some sort of an incognito modus now a days. I myself use Google Chrome the most while developing in ADF.
There is a command line start up parameter to start Google Chrome in incognito modus, a great feature in JDeveloper is that you can set these command line parameters.
If you navigate to (more...)
Recently I’ve been working more and more with JDeveloper Extension Projects. When working with Extension Projects, you deploy to your target platform a lot. I’ve noticed that sometimes, your JDeveloper Platform gets confused with this and the extension you’re working on doesn’t load correctly.
For example, you deploy your extension to the target platform, you follow this deployment in the log file and you see it got deployed successfully. After this, you debug the extension (more...)
If you created an extension project, you can share this with others by creating a zip file. However, there is a powerful mechanism in JDeveloper called Update Centers. This blog will show you how you create an Update Center to share your own Extension Projects.
I’ll use my workspace from this blog
about Audit Rules as example. Step 1 is creating an bundle.xml within your Project source. The bundle.xml should like like this:
Today when trying different settings with Basic Authentication and SOA Suite, I wanted to from the embedded OWSM Policy Repository of JDeveloper to the one stored on the application server. In JDeveloper you can do that through preferences (Tools | Preferences). See this blog for more details.
Click on the App Server Connection option and choose an existing connection through the Connections drop-down or add a new one by clicking New.
Over the last few weeks, I gathered and produced more and more info about Audit Rules, JDeveloper Extension Projects and other stuff related to creating Audit Rules.
I thought it might be wise to create some sort of an index page to refer to all these blogs, guides, articles and (more...)
If you are working with JDeveloper 12c (12.1.2), you will probably have experienced quite a few crashes – I had several during my the live demos in my presentations at the UKOUG Tech 2013 conference in Manchester this week.
A few things that help:
- Increase memory (google “JDeveloper (more...)
Today at the UKOUG I showed a new plug-in for JDeveloper 12c together with Wilfred
, the ADF EMG Audit Rules. You can find it through JDevelopers Check for Updates in the Help menu. This plug-in is a starting point for creating rules out of the code guidelines document you (more...)
Since JDeveloper 12c it’s possible to uninstall extension from your JDeveloper, without deleting jar files and cache directories manually. However, the feature is a little bit hidden, it’s not in your preferences, but in the feature section. You get there through the Tools menu.
Here you can manage your features, (more...)
In this article I explain a handy way to browse the MDS on the SOA/BPM server from JDeveloper, as well as an (as far as I know) undocumented feature to look up artifacts using a browser.
The Meta Data Services (or MDS for short) of Oracle's SOA/BPM Suite is used (more...)
In this article I explain how you can modify the JDeveloper adf-config.xml file to make it work for both Windows, as well as Linux.
If in a JDeveloper application you point to artifacts in a file based MDS residing in a Windows folder for example "d:\projects\MDS", then JDeveloper will (more...)
JDeveloper comes with a nice audit framework, one of the great things about this framework is that you can write your own code to check for specific standards or fire specific rules you want to check. If you want to write extensions in 11g I recommend one off the two (more...)
If you tired from the android emulator speed you may have read Chris Muir’s article ADF Mobile: Avoiding the Android Emulator with AndroVM.
In the meantime the successor of AndroVM is GENYMOTION.
If you have configured the port forwarding section from the AndroVM or use GENYMOTION, then you have to (more...)
We want to test our ADF application with Selenium. To get this working, we use the Selenium IDE (Firefox plugin) to record a session. You can export this recorded session to different formats, since we are mainly Java/ADF developers at our project, we choose to export to Java.
Because we (more...)
Preparing for OpenWorld, I’m updating all my demos to 12c. Unfortunately, my conclusion so far is that nothing works.
The BC tester (now renamed ADF Model Tester) crashes JDeveloper and doesn’t take bind variables. A simple ExecuteWithParams example ignores my parameter value. The list goes on…
Oracle tries to imply (more...)
One of the first things I noticed about 12c is the movement of the panes from the view menu to the window menu. I sometimes get a bit too aggressive in closing a lot of the little panes. When I want to get them back later, I just use the (more...)
Do you know, that PMD can analyse XML files since version 5? Many of ADF files are XML configuration files – wouldn’t it be a good idea to create some static code analysis rules for ADF too?
Unfortunatly oracle configuration files in most times create references to dtd’s, which are (more...)
