Remove Unused Namespaces in JDeveloper by Reinhold Becker

clip_image002This function is deeply missed in JDeveloper by many developers that code with Oracle products. There are many reasons for the usage of removing unused namespaces. Sometimes there are generated into the XML – in other cases we remove an import and forget to delete the namespace. For that reason I created a workaround with no extension coding at all.

The trick is to embed an xslt function into JDeveloper within a Maven script. First you have to create the pom.xml and the transform.xsl into your environment project. If you don’t have an environment project, any other directory will do it. The pom.xml has only one plugin that uses the MOJO project „xml-maven-plugin“. This plugin is used to execute xslt transformations with maven and it only requires the directory and the xsl file. Read the complete article here.

JDeveloper Debugging Tips (Watchpoints & Beep) by Richard Olrichs

clip_image002

In a previous blog post I talked about scoping breakpoints for debugging purposes, next to scoping breakpoints JDeveloper has more interesting debugging features to offer.

I created a simple example to show both the watchpoint as well as the beep functionality. To illustrate this, I created a page with an inputText and a button, both bound to a backingBean.

Now imagine that I want to halt execution everytime the bean field value changes. I can simply right-click the field and choose ‘Toggle Watchpoint’:

JDeveloper 12.1.3: Use Default Activity Instead of the Deprecated Invoke Action by Timo Hahn

clip_image001Since JDeveloper 12.1.3 the invoke action used in earlier version has been deprecated. Users still using the old invoke action to load data on page load should migrate their code to using the default activity in a bounded task flow instead. This article describes how to use the executeWithParams method as a default activity in a bounded task flow (btf) to load data to be shown in a region. For this we implement a common

Use Case:
in a text field the user enters a string which should be used to look-up data in the DB and show the data as a table in a region.
For this we use the HR schema and build a look-up for locations after the name of the city of the location. In a page the user can insert the name or part of a cities name into a text field. This input is send as parameter to a bounded task flow. The default activity of the btf calls a method in the view object which uses a view criteria to search for cities starting with the given input data. In a second implementation the same technique is used but a where clause is used in the VO and the VO is called with executeWithParams. The result of the search is displayed as a table in a region.

Implementation

Model Project:
We start by creating a new ‘Fusion Web Application’ and creating a model project of the HR DB schema. Here we only use the location table for which we create entity object and view object.
Now we create the view criteria which we use to find locations by part of the city name.

Next step is to create the java class for the view object including the method to safely access the created bind variable. In the class we add a method to apply the created view criteria which we expose in the client interface well as the methods to access bind variables. Read the complete article here.

JDeveloper 12.1.3 is good news for Maven fans by Blueberry Coder

JDeveloper 12c 12.1.3 is finally available. The list of new features and enhancements is quite impressive. Have a look! You will not be disappointed. Personally, I was very happy to discover than Apache Maven support has been enhanced in two small but critical areas: paths and archetypes. Don't get me wrong: Maven support in 12.1.2 is leaps and bounds ahead what 11g offers. But the tweaks brought in 12.1.3 make a significant difference. The main issue with the Maven support in 12.1.2 is that the POM files generated by JDeveloper contain absolute paths. This is problematic, since applications will not


compile correctly unless the code resides in the same location on all developer workstations and build servers. This is not always possible or even desirable. Thus, I described how to replace those absolute paths with relative ones in a previous blog post. Fortunately, JDeveloper 12.1.3 does things differently and writes its POMs with relative paths instead.
Maven archetypes help developers create new applications from scratch from the command line. It is now possible to build a new ADF application that way using the oracle-adffaces-ejb archetype introduced by Oracle in JDeveloper 12.1.3. The resulting application will use EJB for its model layer. To use the archetype, simply issue a command like the one below:
mvn archetype:generate -DarchetypeGroupId=com.oracle.adf.archetype
-DarchetypeArtifactId=oracle-adffaces-ejb
-DarchetypeVersion=12.1.3-0-0
-DgroupId=oracle.test
-DartifactId=my-maven-test
-Dversion=1.0-SNAPSHOT
Obviously, this command will be successful only if the Maven binaries directory has been added to the path. Remember that Maven is provided by JDeveloper and can be found in the ORACLE_HOME/oracle_common/modules directory - although you can use your own install instead. If you prefer to use a GUI, you can create an application from inside JDeveloper by using a little known option introduced in 12.1.2. First, open the New... gallery and select the Maven subcategory (under the General category). Then, select the Generate from Archetype item. This will bring up the dialog shown below.

The Future of Application Development Tools at Oracle by Tori Wieldt

Last week we met with Chris Tonas, Vice President of Mobility and Application Development Tools at Oracle, to hear his take on the latest in the world of Java tooling and development frameworks.

Q: Can you tell us a little bit about your role at Oracle as it relates to development tools?
A: I lead the organization that is working on Oracle’s software development tools and frameworks, specifically, the teams that build our offerings for Java developers - whether in NetBeans, Eclipse or JDeveloper. Our team also builds the tools and frameworks that are used by developers working with Oracle’s cloud and mobile platforms.

Q: This week saw the release of JDK8 and NetBeans 8 along with it. How do you view this release?
A: The release of JDK 8 and NetBeans 8 this week represents a big step forward for both Oracle and the Java Community. A lot of hard work and collaboration went into this milestone and I’d like to take a moment to thank everyone who contributed to this achievement.

Q: With the new NetBeans 8.0 out, what are the plans for NetBeans going forward?
A: In the short term, an update release of NetBeans 8 is underway to align with Java ME 8. Additional NetBeans 8 releases that target specific bugs are anticipated to be released after that. Longer term, Oracle is committed to the continued success of both Java and NetBeans. Work on JDK 9 is now underway and we’re planning a NetBeans 9 release to go along with it, as usual.

dukeQ: As you mentioned Oracle supports more than just the NetBeans IDE. What’s the thinking behind that?
A: Oracle recognizes that developer tools aren’t a one-size-fits-all proposition. Oracle is a significant contributor to the Eclipse project and we are continuing to extend the capabilities of our Eclipse-based solutions as well. We offer JDeveloper for those who want the tightest alignment with the Oracle Fusion Middleware stack. In addition, we recognize that many JavaScript developers want to use light weight tools, and we are planning to address those needs as well.

Q: What are some of the key trends you see in the software development space right now?
A: It’s clear that several significant trends are shaping software development and tools. Oracle is at the forefront of these changes and a leader in almost every aspect. We see three main changes happening right now: Read the complete article here.

Working with the select Many Checkbox component by Antonis Antoniou

I recently came across a simple, yet not so straightforward use case as it seems for many ADF developers on the JDeveloper & ADF forum so I decided to blog about it.

The requirement was to use the selectManyCheckbox component and to save the selection in the database in a varchar2 column of type.

So I created a custom table in the HR schema, MY_EMPLOYEES with 3 columns; ID (number), NAME (varchar2) and DEPARTMENTS (varchar2).

I then created the basic ADFBC objects (an entity MyEmployees based on the MY_EMPLOYEES table, a view MyEmployeesView based on the MyEmployees entity and an application module AppModule that has the MyEmployeesView selected in the data model). Read the complete article here.
