The properties information for each component forming a Route allows to set the actual technical implementation of the active Route.

Each component is defined by basic and advanced properties shown respectively on the Basic Settings tab and the Advanced Settings tab of the Component view of the selected component in the design workspace. The Component view gathers also other collateral information related to the component in use, including View and Documentation tabs.

For detailed configuration for each component displaying in the Palette of the Route builder, see Talend ESB Mediation Components Reference Guide.

Basic Settings tab

The Basic Settings tab is part of the Component view, which is located on the lower part of the designing editor of Talend Studio.

Each component has specific basic settings according to its function requirements within the Route. For a detailed description of each component properties and use, see Talend ESB Mediation Components Reference Guide.

How to set a field dynamically (Ctrl+Space bar)

On any field of your Route/component settings view, you can use the Ctrl+Space bar to access the global and context variable list and set the relevant field value dynamically.

  1. Place the cursor on any field of the Component view.

  2. Press Ctrl+Space bar to access the proposal list.

  3. Select on the list the relevant parameters you need. Appended to the variable list, a information panel provides details about the selected parameter.

This can be any parameter including: error messages, system variables, etc. The list varies according to the component in selection or the context you're working in.

Advanced settings tab

Some components, for example the cMessagingEndpoint component, can require advanced settings in some cases to function properly.

The content of the Advanced settings tab changes according to the selected component.

Generally you will find on this tab the parameters that are not required for a basic or usual use of the component but may be required for a use out of the standard scope.

View tab

The View tab of the Component view allows you to change the default display format of components on the design workspace.

Field

Description

Label format

Free text label showing on the design workspace. Variables can be set to retrieve and display values from other fields. The field tooltip usually shows the corresponding variable where the field value is stored.

Note

It is recommended to label each component with a unique name to better identify its role in the Route. This is especially useful for the code generation of some components, for example, the cCXF component. For more information, see Talend ESB Mediation Components Reference Guide.

Hint format

Hidden tooltip, showing only when you mouse over the component.

Connection format

Indicates the type of connection accepted by the component.

You can graphically highlight both Label and Hint text with HTML formatting tags:

  • Bold: <b> YourLabelOrHint </b>

  • Italic: <i> YourLabelOrHint </i>

  • Return carriage: YourLabelOrHint <br> ContdOnNextLine

  • Color: <Font color= '#RGBcolor'> YourLabelOrHint </Font>

To change your preferences of this View panel, click Window>Preferences>Talend>Designer.

Documentation tab

Feel free to add any useful comment or chunk of text or documentation to your component.

In the Documentation tab, you can add your text in the Comment field. Then, select the Show Information check box and an information icon display next to the corresponding component in the design workspace.

You can show the Documentation in your hint tooltip using the associated variable _COMMENT_, so that when you place your mouse on this icon, the text written in the Comment field displays in a tooltip box.
