IntelliJ IDEA 2019.2 Help

Run/Debug Configuration: Applet

An applet run/debug configuration enables you to run Java applets using an applet viewer or a Web page and your local browser.

Item

Description

Name

In this text box, specify the name of the current run/debug configuration.

Applet Class

Choose this option to create a configuration profile for running an applet via an applet class.

URL

Choose this option to create a configuration profile for running an applet via a Web page.

Applet Class

Use the controls in the area to specify the applet implementation class and the applet size.
  • Applet Class - in this text box, specify the fully qualified name of the applet class to run. Type the name manually or click the Browse button the Browse button to open the Choose Applet Class dialog box and select the path there.

  • Width - in this text box, type the desired width of the applet.

  • Height - in this text box, type the desired height of the applet.

The area is available after the Applet Class option is chosen.

Applet Parameters

In this area, specify a set of applet parameters.
  • Add - click this button to add a new entry to the list.

  • Remove - click this button to delete the selected entry from the list.

  • Name - in this text bos, specify the name of the applet parameter.

  • Value - in this text bos, specify the parameter value.

This area is available after the Applet Class option is chosen.

URL

In the URL/HTML File text box, specify the file to invoke the applet from. Type the path to the file manually or click Browse the Browse button and select the file in the dialog that opens.

This area is available after the URL option is chosen.

Policy File

In this text box, specify the location of tje appletviewer.policy file. Because this file is distributed with IntelliJ IDEA, the text box is by default filled in with the standard location. To specify another location, click Browse the Browse button and choose the desired location in the dialog that opens.

VM Options for Applet Viewer

In this text box, specify the string to be passed to the VM for executing the applet viewer. Usually this string contains the options such as -mx, -verbose, etc.

If necessary, click icons general expandComponent svg and type the desired string in the VM Options dialog.

When specifying JVM options, follow these rules:

  • Use spaces to separate individual options, for example, -client -ea -Xmx1024m.

  • If an option includes spaces, enclose the spaces or the argument that contains spaces in double quotes, for example, some" "arg or "some arg".

  • If an option includes double quotes (as part of the argument), escape the double quotes using backslashes, for example, -Dmy.prop=\"quoted_value\".

  • You can pass environment variable values to custom Java properties. For example, if you define a variable MY_ENV_VAR, you can pass it to the foo property as follows:

    -Dfoo=${MY_ENV_VAR}

The -classpath option specified in this field overrides the classpath of the module.

Use Classpath and JDK of the Module

From this drop-down list, select one of the modules configured in your project. The classpath and JDK of this module will be used to run the applet with the current run configuration.

Use Alternative JRE

Select this checkbox to enable defining another JRE than the JRE used by the current project / module.

Common

When you edit a run configuration (but not a run configuration template), you can specify the following options:

Item

Description

Name

In this field, specify the name for the run/debug configuration. The name will help you identify the created configuration when you choose to edit it later, or when you invoke it, for example, from the Run popup Shift+Alt+F10.

Share through VCS

Select this checkbox to put the run/debug configuration under version control and make it available to other team members.

If the directory-based project format is used, the settings for a run/debug configuration are stored in a separate .xml file in the .idea\runConfigurations folder if the run/debug configuration is shared, or in the .idea\workspace.xml file otherwise.

If the file-based format is used, the settings are stored in the .ipr file for shared configurations, or in the .iws file otherwise.

Allow running in parallel

If this checkbox is selected, it is possible to launch a run configuration multiple times in parallel instead of rerunning it. Each runner will start in its own tab of the Run Tool Window or Debug Tool Window.

When disabled, every time a new instance of the run/debug configuration is launched, IntelliJ IDEA checks the presence of the other instances of the same run/debug configuration, and displays a confirmation dialog. If you click OK in the confirmation dialog, the first instance of the runner will be stopped, and the next one will take its place. This makes sense when launching two instances of run/debug configurations of the same type consumes too much of the CPU and memory resources..

Toolbar

The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your project as well as adjust default configurations templates.

Item

Shortcut

Description

the Add buttonAlt+Insert

Create a run/debug configuration.

the Remove buttonAlt+Delete

Delete the selected run/debug configuration. Note that you cannot delete default configurations.

Copy Ctrl+D

Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.

Save configuration

The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.

Edit Templates

View and edit the template (that is, the default settings) for the selected run/debug configuration. The templates are displayed under the Templates node and used for newly created configurations.

Method up/Method down

Alt+Up/Alt+Down

Move the selected run/debug configuration up and down in the list.

The order of configurations in the list defines the order, in which the configurations appear when you choose a run/debug configuration.

Default templates of run/debug configurations are always sorted alphabetically.

Move into new folder / Create new folder

Move into new folder / Create new folder. You can group run/debug configurations by placing them into folders.

To create a folder, select the configurations within a category, click Folder, and specify the folder name. If only a category is in focus, an empty folder is created.

Then, to move a configuration into a folder, between the folders or out of a folder, use drag or Move Up and Move Down buttons.

To remove grouping, select a folder and click Remove Configuration.

Sort configurations

Click this button to sort configurations in the alphabetical order.

Before Launch

In this area you can specify tasks that must be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.

    If an error occurs during compilation, IntelliJ IDEA won't attempt to start the run/debug configuration.
