The tLogCatcher component can catch exceptions from three types of components: tWarn, tDie, and

Java Exception. The tWarn component is used to trigger a warning message that can be caught by the

tLogCatcher component for an exhaustive log. The tDie component is used to stop the execution of a

job or a subjob and return an error code that can be caught by the tLogCatcher component for an

exhaustive log. The Java Exception component is used to handle any Java exception that occurs

during the execution of a job or a subjob and pass it to the tLogCatcher component for an exhaustive

log. The tLogCatcher component cannot catch exceptions from other types of components, such as

OnSubjobError Exception or tAssertCatcher. The OnSubjobError Exception is a trigger that is activated

when an error occurs in a subjob and can be used to perform some actions after the error, such as

sending an email or logging a message. The tAssertCatcher component is a component that collects

the assert data generated by the tAssert component and passes it on to the output defined. The

tAssert component is used to verify if a condition is true or false and generate an assert data

accordingly. Reference: Talend Open Studio: Open-source ETL and Free Data Integration | Talend,

To execute the compiled job outside Talend Studio, you need to right-click on the job in the

Repository tree view and select Build Job option. This option allows you to export your job as an

executable file that can be run independently from Talend Studio on any platform that supports Java.

You can access this option by right-clicking on your job in the Repository tree view and selecting Build

Job. This will open a dialog box where you can configure the build settings, such as destination folder,

archive name, context, etc.

You do not need to click the Export button in the Edit Properties window, right-click on the job in the

Repository and select Export items, or select Save As on the main File menu. These options are not

used to execute the compiled job outside Talend Studio. The Export button in the Edit Properties

window is used to export your job properties as an XML file. The Export items option is used to

export your items (such as jobs, metadata, routines, etc.) as an archive file that can be imported into

another project or workspace. The Save As option is used to save a copy of your job with a different

name or location. Reference: Talend Open Studio: Open-source ETL and Free Data Integration |

Contexts are a way of defining different sets of values for variables that are used in a job. For

example, you can define a context for testing and another context for production, with different

values for the database connection parameters, file paths, etc. You can then switch between the

contexts easily without modifying the job design. Contexts are not automatically defined by the

types of components used in the job, nor by Talend Studio. You must define the contexts yourself in

the Contexts tab of your job. You can also create context groups in the Repository and reuse them in

multiple jobs. Reference: Talend Data Integration — Software to Connect, Access, and Transform

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

To call a different job within a job you are developing, you can use the tRunJob component. This component allows you to execute another job as a subjob within a parent job. To pass the parameters to the job you want to call, you can use the context parameters. Context parameters are variables that can store values that can be changed at runtime or between different contexts. You can define context parameters in the Contexts tab of your job and assign them values for each context. You can also pass context parameters from the parent job to the child job by using the Context Param tab of the tRunJob component. This way, you can parameterize the properties or expressions of the child job with the values from the parent job. To transfer processed data stored in the tBufferOutput buffer memory back to the parent job, you need to select the Propagate the child result to output schema option in the Advanced settings of the tRunJob component. This option allows you to retrieve the data from the tBufferOutput component of the child job and send it to an output row of the parent job. The tBufferOutput component is used to store data in memory without writing it to disk or database. You can use this component to optimize the performance and memory usage of your job. You do not need to select the Transmit whole context option in either Basic or Advanced settings of the tRunJob component. This option allows you to pass all the context parameters from the parent job to the child job without specifying them individually. This option does not affect the data transfer from the tBufferOutput component. You also do not need to select the Propagate the child result to output schema option in Basic settings of the tRunJob component, as this option is only available in Advanced settings. Reference: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [tRunJob properties - 7.3], [tBufferOutput properties - 7.3], [Contexts - 7.3]
