To enable SSL for a JobServer, you need to edit the conf/TalendJobServer.properties file. A JobServer is a server application that allows you to execute jobs remotely from Talend Studio or Talend Administration Center. The conf/TalendJobServer.properties file contains various configuration parameters for your JobServer, such as port number, log level, security options, etc. To enable SSL for your JobServer, you need to set the ssl parameter to true and provide the path and password of your keystore file that contains your SSL certificate.

You do not need to edit conf/TalendServer.properties, conf/server.xml, or jsl_static64.ini files. These files are not related to JobServer configuration or SSL settings. The conf/TalendServer.properties file is used to configure Talend Administration Center settings, such as database connection, LDAP authentication, email notification, etc. The conf/server.xml file is used to configure Tomcat server settings, such as connectors, realms, valves, etc. The jsl_static64.ini file is used to configure Java Service Launcher settings, such as service name, description, startup type, etc.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Configuring Talend JobServer - 7.3], [Configuring Talend Administration Center - 7.3], [Configuring Tomcat - 7.3], [Installing Java Service Launcher - 7.3]

To create an empty Joblet, you need to right-click on the Joblet Designs node in the Repository tree view and select Create Joblet option. This will open a dialog box where you can enter the name and description of your Joblet and select an icon for it. You can then design your Joblet by adding components and links to it in the Designer workspace.

You cannot create an empty Joblet by creating an empty job, then exporting it as a Joblet by right-clicking it in the Repository, creating an empty job and using the file menu to save it as Joblet, or right-clicking a space in the Designer and selecting refactor to Joblet. These methods are not available in Talend Studio and may cause errors or unexpected results.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Joblets - 7.3]

Using the following input file format as an example:

<OCR>Name, Phone Abraham Smith, 510-555-5555 ... Steven Doe, 613-555-5555 </OCR>

The tFileInputDelimited component parameters that you should configure to parse the input file correctly are Schema, Field separator, and Header. The Schema parameter defines the structure and type of the data in the input file. You can use a built-in schema or a repository schema to specify the columns and their properties. The Field separator parameter defines the character that separates each field in a row of data. In this case, it is a comma (,). The Header parameter defines the number of rows to be skipped at the beginning of the file. In this case, it is 1, as the first row contains the column names.

The Start component in a subjob triggers the execution of the next subjob in a sequential order. The Start component is used to define where a subjob begins and to link it with other subjobs within a job. The Start component has only one output link that can be connected to any other component in the same subjob or to another Start component in another subjob. When a subjob completes successfully, it sends an OnSubjobOk trigger to its Start component, which then activates the next subjob linked to it. The Final component, on the other hand, is used to define where a subjob ends and to perform some actions after its completion, such as sending an email or logging a message. The Final component has no output link and does not trigger any other subjob. The Input component and any other component in a subjob do not trigger any other subjob by themselves, unless they are connected to a Start component through an output link or an OnComponentOk trigger.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Start properties - 7.3], [Final properties - 7.3]

To retrieve records that have a specific value based on a variable, you can use a tDBInput component with a context variable in the SQL query. A context variable is a variable that can store a value that can be changed at runtime or between different contexts. A context variable can be used in various components to parameterize their properties or expressions. A tDBInput component is used to read data from a database table by executing an SQL query. You can use a context variable in the SQL query to filter the records based on a dynamic value. For example, if you have a context variable named country that stores the value of the country you want to filter by, you can use it in the SQL query of the tDBInput component as follows:

SELECT id, address, country FROM customers WHERE country = 'context.country'

This will retrieve only the records that have the same value as the context variable country in the country column.

You do not need to use a Run if trigger, a tMatchGroup component, or a tFilterColumns component to achieve this. A Run if trigger is used to execute a subjob conditionally based on a logical expression. A tMatchGroup component is used to group similar records based on matching rules and output them as master or duplicate records. A tFilterColumns component is used to select or remove columns from an input flow based on a list of column names.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Contexts - 7.3], [tDBInput properties - 7.3], [Run if properties - 7.3], [tMatchGroup properties - 7.3], [tFilterColumns properties - 7.3]
