tWebServiceInput Standard properties

Property type

Either Built-in or Repository.

Built-in: No property data stored centrally.

Repository: Select the Repository file where the properties are stored. The fields that follow are completed automatically using the data retrieved.

Click this icon to open a WSDL schema wizard and store your WSDL connection in the Repository tree view.

For more information about setting up and storing database connection parameters, see Talend Studio User Guide.

Schema and Edit Schema

A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either Built-in or stored remotely in the Repository.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this option to view the schema only.

• Change to built-in property: choose this option to change the schema to Built-in for local changes.

• Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.

Built-in: You create the schema and store it locally for the relevant component. Related topic: see Talend Studio User Guide.

Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job flowcharts. Related topic: see Talend Studio User Guide.
