If I give complete path of the file, it works. How to overcome this? How to fix this? Freddy Wong. I like It's because the path is wrong.
If you put the property file like this properties. Probably the best way is to either specify the property file path in the System property or you can also put it in the classpath and scan for that file. If you want to have a quick hack to see if your program can read the properties file, create the Config. Go to the Files tab and create it in the same level as build.
Hope this helps. When removeNotify is called, it removes the listener, as it is no longer interested in receiving notifications. In addition, refresh is called. This method is defined by ChildFactory for use by the subclasses. It is passed the key for which it is making a node. It returns either none, one, or more nodes corresponding to what should be displayed for the key.
In this example, a new instance of one property node is being created, and the system property name is passed into its constructor. This call goes through all of the property names, keeping and sorting this list. This Java class provides the AbstractNode implementation for a single property. Its constructor requires a string key. This class displays a single system property name.
It then stores the key and sets the icon. In this example, the default action is to pop up the property sheet. The inherited version is used, to set the node name it does not attempt to rename the actual property. This creates the list of tabs in the property sheet, along with the list of properties. If not, Sheet. Note that Sheet refers to the entire set of properties for the node, and Sheet. Set is one tab in the property sheet. The code is already synchronizing the node name with the system property name.
ReadWrite is the base class for entering and viewing values. The super call provides a code name for the property as well as a display name and a tool tip for the user. The property is added to the property sheet, along with a ChangeListener , which listens for changes in system properties, which may mean that this specific property has changed. If true, then the firePropertyChange node fires a change to say that one of the properties in its property sheet is no longer valid, and checks and updates should be made accordingly.
Note that the name of the property is value, which matches the internal name assigned when creating ValueProp.
This action retrieves all system properties and associated values, removes the key, adds a new property with a new name and value, and sets the system properties. This action also notifies all concerned that it has changed, though it does not directly rename itself see AllPropsChildren next. The node is actually removed later, by AllPropsChildren. AllPropsChildren realizes this property no longer exists, and creates a new set of keys that no longer includes this property.
Then the ChildFactory implementation automatically removes that node. This is done to reflect the actual state of the system. This Java class provides the "Refresh" action that appears in the pop-up menu under the "System Properties" main node. It is a CallableSystemAction and is always enabled, yet is not sensitive to what is selected. In principle, it could also be placed as a button in a toolbar.
The important methods that should be defined when implementing CallableSystemAction are:. For example, a new property may have been added or an existing value may have been changed. Once you have coded the main files, you must specify how you want your Module to impact the filesystem and what labels and texts you want to display to the user.
The layer. For the icons used to display the nodes, you can use any 16x16 icons you want, so long as they are named allPropsIcon. Alternatively, get the icons from the ZIP file attached to this tutorial.
Now that you have completed your module, it is time to try it out. The IDE uses an Ant build script to build and install your module. The build script was created for you when you created the module project. The module is built and installed in the target IDE or Platform.
Use the module as described in the Introducing the Sample section. Send Us Your Feedback. Apache NetBeans. Latest release. Getting to Know the Sample This tutorial will help you understand the following:. Installing the Sample In this section, we download and install the sample, so that we can become acquainted with it before recreating it ourselves. Introducing the Sample In this section, we look at the functionality provided by the module, from the perspective of an end user. Play with the sample: Show the property sheet.
Introducing the Sources The System Properties sample consists of main files and supporting files. Setting Up the Module Project Before you start writing the module, you have to make sure you that your project is set up correctly.
Creating the Module Project In this section, we use the New Module wizard to create the source structure needed by all module projects. The following methods are used: RefreshPropsAction is an action defined in another source file NewAction enables the creation of a new subnode or key-value pair OpenLocalExplorerAction permits the user to make a new Explorer window showing only system properties.
Here is an explanation of the class:. Setting Up the Supporting Files Once you have coded the main files, you must specify how you want your Module to impact the filesystem and what labels and texts you want to display to the user. Add the following properties to the Bundle. Building and Installing the Module Now that you have completed your module, it is time to try it out.
