Custom ADF Skin: Consume as Library

Tested with JDeveloper:
Main purpose of this post is for me to have a reference project and proof of concept using an ADF Skin as Library.
Part 1: Skin Application
So first the ADF Skin project should be created. Since JDevR2 this process has been simplified by new ADF Skin wizard.
In the next screen just give your skin a name and extend from the fusionFx-simple-v2.desktop Oracle Skin. It is specially designed with extensibility in mind for cusom skins. Fortunataly the recommended skin is selected. (It is not with every ADF/Jdeveloper feature ;). So well done Oracle!
The following bunch of things is created on the fly
Now lets create a "green" skin with smallest amount of modifications. This is achieved by opening the CSS file and
go to the "Images" View. Just change some of the colors.
And afterwards click "Apply to Skin"
=> This will generate a lot of images according to your color schema.
In order to support versioning of skin I am adding the following to the trinidad-skins.xml
Now we are ready to bundle the custom skin as ADF library. There is nothing special here. Create the Deployment profile, keep defaults and deploy.
Next step is to test the provisioning of the ADF Skin through ADF Library through File System connection. To do that we create a filesystem connection in the resource pallete
The Skin shows up as expected
Part 2: Consume ADF Skin
a) Create an pure empty Fusion ADF Application by wizard.
b) Select the ViewController project
c) Select adflib-myskin.jarm Right Click and Click add to Project
The Message Pane should output something like
These ADF Library jar items are now in ViewController.jpr
  These are in the project as a result of your ADF jar imports:
  Resource Bundle Variable Resolver from .../TestADFSkin/MySkin/MySkin.jpr
d) Apply custom ADF Skin as default in Project Properties>ADF View
e) Create a simple JSF Page based on the threeColumnTemplate and  take a look
At Design-Time there seem to be some problems.
At Runtime it looks as expected
Is it a Bug at Design Time?
Using just a QuickLayout everything is as expected also in design time

RESTful Management Services in Oracle WebLogic Server 12c

Version: 12.1.1 (developer edition, ZIP, no installer)


unzip wls1211_dev as follows


In order to be able to work with this edition we have to call configure.cmd. This basically unpacks all jars, create the registry.xml and wlserver\.product.properties

To have some reusable snippets I have created additional scripts in the new MW_HOME


@echo off
@rem ***************************************************************************
@rem This script is used to set the environment for
@rem Oracle WebLogic Server 12.1.1 dev ZIP edition
@rem ***************************************************************************

set MW_HOME=C:\oracle\product\12.1.1\middleware
set JAVA_HOME=C:\oracle\product\\middleware\jdk160_24


@echo off
@rem ***************************************************************************
@rem This script is used to install Oracle WebLogic Server 12.1.1 dev ZIP edition
@rem ***************************************************************************

call env_wls1211_dev.cmd

title Installing WLS

call %MW_HOME%\configure.cmd


Now execute install_wls12c_dev.cmd

In order to create a domain by configuration wizard

a) call env_wls12c_dev.cmd

b) %MW_HOME%\wlserver\common\bin\config.cmd

RESTful Management Service API

Sounds cool...lets try

Activate by Domain > Configuration > Advanced Configuation > Enable RESTful Management Services

=> (restart required)

After restart you will notice the following in the output

INFO: Scanning for root resource and provider classes in the packages:

INFO: Initiating Jersey application, version 'Jersey: 1.9 09/02/2011 11:17 AM'

(=> This is good news! It states that some RESTful service will be available.)

After Restart open http://localhost:7001/management/tenant-monitoring/servers

(the authorized users must be in the group Administrators or Monitors)


Login in as weblogic user and see the default HTML output


If you e.g. need better proccessable formats, JSON and XML are of course also supported. Let's see how it is done and what it looks.

Add Accept Header with application/json


Add Accept Header with application/xml


Currently there is REST support for Servers (all in a domain or specific one), Clusters ( all in a domain or specific incl server members), applications (all in a domain or specific app), data sources (all in a domain or specific).

With these capabilities it' possible to implement a custom monitoring solution. A slim mobile wls monitoring app (and more)! => Hands on;)

See doc for details of all available RESTful-Services in WLS12.1.1 http://docs.oracle.com/cd/E24329_01/web.1211/e26722/toc.htm

- Still many BEA* stuff in diffrent scripts. It would be nice to have a clean and straight product without any historical garbage.

- configure.xml : ProgramGroupName=BEA WebLogic Platform 10.3 (Integrated Build)....

Why there is still the need to have a programm group called "BEA WebLogic Platform 10.3"?

My suggestions: Oracle WebLogic Platform 12.1.1 or Oracle Fusion Middleware Platform 12.1.1, everythin else, but not 10.3!


- Java EE 6 Support. (It took a long time..)

- Better Maven Support

- RESTful Management Service

- ZIP distribution. Although the file is called wls1211_dev.zip it is possible to create a domain in production mode by the configuration wizard. At least in a simple testdrive it worked for me.

-Startup time feels better than wls11g

- more to test...(-Dservertype=wlx  to avoid loading EJB, JMS, JCA )

ADF News Session (german) - Integration of BI Publisher into ADF Applications

The folowing session was presented today on the german ADF News Session that is driven by the german ADF community.

Although the slides are in german I think the ADF concepts should be well decoupled from the language itself ;)

ADF: Panel Tabbed Inter-Region Communication through shared bean datacontrol

Tested with JDeveloper

Use Case

  • JSF Page with two tabs (Departments, Employees)
    image The DepartmentName is rendered as a command link. If the user clicks on a DepartmentName the view changes on to the Employees Tab and filters the data
  • In each tab there is an static adf region (bound to fragment based BTF)
In summary we need the following to do:
  • DepartmentName as command link
  • View switches to the Employees Tab
  • Tab text should change to “Employees (<DepartmentName>)
  • On the employees tab - of course – only the corresponding entries should be displayed
  • The employees tab contains a button to remove the “global” filter.

How to do it?

Create DataExchange Bean as follows
public class DeptEmpExchange {
    private Number deptId;
    private String deptName;
    public DeptEmpExchange() {
        System.out.println("DeptEmpExchange created " + this);
    public void setDeptId(Number deptId) {
        this.deptId = deptId;
    public Number getDeptId() {
        return deptId;
    public void setDeptName(String deptName) {
        this.deptName = deptName;
    public String getDeptName() {
        return deptName;
     * Exposed as DC Operation.
     * Called from the dept btf
     * @param deptId
     * @param deptName
    public void onDepartmentChange(final Number deptId,
                                   final String deptName) {
        System.out.println("onDepartmentExchange called: " + deptId + "/" + deptName);
        View1Bean view1 = (View1Bean)JSFUtils.resolveExpression("#{View1Bean}");
        view1.setEmpTabText("Employees ("+deptName+")");
And expose as JavaBean DataControl.
Now, on depts page fragment: drop the exposed operation onto the command link and provide the parameters from the current row.
The refresh of the panel tabbed is done programmatically in the onDepartmentChange(..) method. In order to refresh the emp btf with the new dept id configure the following bindings / properties on the main page
- create an attribute binding on the deptId from the DeptEmpExchange Bean.
- bind the tf input parameter to the attribute binding
- do not forget to set refresh=ifNeeded => this causes the btf to refresh in case the input params will change.
Implementing the “remove global filter” functionality is pretty simple. Just drag the onDepartmentChange-Operation from the data control palette on to the toolbar and adjust the text.

I hope I have not forgotten any important steps.

ADF Faces: Navigate on Checkbox selection

Used in Version:

As you may have noticed there is no action attribute on af:selectBooleanCheckbox. So how could you trigger a navigation case if user changed selection state of the checkbox.

In a customers scenario I need to trigger a navigation in a BTF from a checkbox insige a jsff

<af:selectBooleanCheckbox label="Klick me" id="sbc1"


MyBean.java looks like

 public void setSelected(String value) {
final FacesContext context = FacesContext.getCurrentInstance();

if ("true".equalsIgnoreCase(value)) {
// checkbox is selected

// checkbox is not selected

ADF - clicktoedit table, createinsert, rollback bug?

ADF version:
Firefox: 5.0


-Using ADF BC
-Create the most simple jsf page declarativly (no custom java code)
--table features: single selection, sorting, filtering
--change table attributes: editingMode=clickToEdit

Steps to reproduce

1. start


[notice the yellow marked rows.]

2. Now Click on CreateInsert


OK, new row is inserted and can be edited now.

3. Click on Rollback-Button (or Execute-Button)


What happened to the last two rows?

Further issue: clicktoedit not working on some rows


You may click as often you want. The row won't change into edit mode. In the log window you will see

<FacesCtrlHierBinding$FacesModel> <makeCurrent> ADFv: Keine Zeile gefunden für rowKey: [oracle.jbo.Key[191 ]].

Known workaround so far

1. Click the Execute-Button after Rollback.

2. Bind Rollback action to a backing bean method and do the following (Rollback + setActiveRowKey)

* Rollsback and Re-Executes the table iterator
* @param actionEvent
public void onRollback(ActionEvent actionEvent) {
    final DCBindingContainer bc = (DCBindingContainer)getBindings();


* @param bc
private void setActiveRowKey(final DCBindingContainer bc) {
    final DCIteratorBinding empIter = bc.findIteratorBinding("EmployeesView1Iterator");
    final Row newRow = empIter.getCurrentRow();
    final ArrayList activeRowKeyList = new ArrayList();

public BindingContainer getBindings(){
    return BindingContext.getCurrent().getCurrentBindingsEntry();

JDev – Clear WLS Log tab Bug?

Applies to JDeveloper:

Problem Description

After starting the integrated WLS from JDev the wls log is displayed in the log tab. Open mouse context menu and “clear” item is not activated


I have no chance to clear the log tab!! Arghh.

Is there any good reason for this behaviour? ( not beeing able to clear the log). The memory consumption is already enormous. Dear Oracle, please let me clear the log tab again…

Never seen this issue in 11gR1 versions.

Is there any workaround?

[solved] Download offline bc4j-junit_bundle version/download link mismatch

Applies to: JDeveloper

Download from: http://www.oracle.com/ocom/groups/public/@otn/documents/webcontent/131167.xml#oracle.BC4J.junit

Problem description

Trying to install the downloaded bc4j-junit_bundle offline version as extension I get the following error



Open the corresponding bundle ZIP an lets see if it is really wrong version


But as you can see I have downloaded the correct version. So there is a mismatch.


After further investigating the download link I realized that it just references the old version


So let's try to adjust manually the URL und download


é voilà now the installation works fine as well


[solved] JDeveloper - Install Extensions offline / licences check issue

Applies to: JDeveloper



Results in


The impact is that you are unable to install JUnit-Extension in a Workshop Lab e.g. where

you can't assume that the attendees have an internet connection


Because we are quite smart let's workaround....

Open Bundle with your favourite archiver tool

and remove or comment out the following line

<u:requires-agreement url="http://junit.sourceforge.net/cpl-v10.html" />


Save change and Update Archive.

Import extension again.


=> No license check requirement shows up. Yeeeees we can!

Upgrade Oracle Team Productivity Center to / Hudson Plugin

From Version: 
To Version:


Check the content of the current otpc schema

SQL> select * from otpc_version t;

                 ID       DB_UPGRADE_NUM DB_VERSION                                                                    VERSION

-------------------- -------------------- ---------------------------------------------------------------- --------------------

                  1                    2                                                                   1

Download tpcinstaller.jar from OTN


Start new installer

jar -jar tpcinstaller.jar


Click Next


Great: The installer recognized everything, so you really can expect the installation process will do the right thing

Choose: NExt


Point to the autodeploy directory of the privious installation. If you just point to the DOMAIN_HOME Location you will get an exception:


TPC-90026: The otpc.war of current installation for upgrade is missing in the server deployment directory

(Enhencement request: The installer should be smart enough to be able to check for otpc.war in the given domain!)


Choose: Next


Choose: Next






Upgrade completed. Plus Hudson Plugin installed.

Verify installation/ Upgrade

Verify  otpc_version in database schema:

SQL> select * from otpc_version t;

                 ID       DB_UPGRADE_NUM DB_VERSION                                                                    VERSION

-------------------- -------------------- ---------------------------------------------------------------- --------------------

                  1                    2                                                                   2


Everything worked as expected. Nice.

Lets start weblogic and check if otpc server is running


Seems to run, but (as stated in one of my privious posts) nobody can be sure which version actually is running. Especially from an ALM tool which now integrates with hudson I REALLY CAN EXPECT to see a BUILD-Number here! Dear Oracle, if you are reading this, please log an enhencement request to integrate a build number in the otpc server homepage! Further it would be nice if that homepage lists all installed otpc plugins (plus which version of course). Thanks.


After starting the new otpc server a new folder has been created in DOMAIN_HOME


=> Oracle uses ActiveMQ now. I think in order to be able multi app server compatible. And ActiveMQ is obviously tinier than the WLS one.

OTPC Hudson Plugin

Now I am really interessted in how the hudson plugin looks like. So lets start my local hudson sanbox.

java -jar hudson-2.1.1.war -httpPort=8081 (8080 is used by the XE DB)

Observing the Hudson > Plugin Manager > Installed

=> No hints to a newly installed plugin

Looking into Hudson > Plugin Manager > Available

=> Bingo.


(Additional info. The plugin has been put to


by the OTPC installer and not into the $HUDSON_HOME/plugins/ as I would expect.)

Ok, move on


Restart hudson.

The otpc plugin shows up in the installed section of the plugin manager.


So now we can use the plugin in our hudson jobs. Choose your job and configure..


Save changes and run your job.

Check the jobs console output

"The test result(s) Testergebnis will be sent to the Oracle Team Productivity Team Server at http://localhost:7001.

Successfully loggedin."

Thats all so far. Nothing else shows up in your hudson ui ;-(

What's next

Check OTPC in new JDev




Let's open an old task repository


Hhhm. let's create a new task repository


Same problem here.


OTPC is still not enterprise ready. OTPC should improve in the following

  1. Task repository connection does not work in new version! Wow. Where is the mistake? the server logs

  1. Integration BUILD-Number into otpc server homepage

  2. List installed connectors on otpc server homepage

  3. Integrate LDAP vor OTPC Users/Groups. Provide a mapping from those users/groups to OTPC Roles

  4. Integrate some nice charts in the hudson jobs webpages ;)
