Using the tDataprepRun component with an HTTPS connection

Last updated: 9/1/2026

Procedure

Retrieve Talend Data Preparation certificate, or its Certificate Authority and add it to an existing or new .jks file following this example:
keytool -import -trustcacerts -alias <cert-alias> -file <dp_certificate.crt> -keystore <truststore.jks>
To make the Studio trust the Talend Data Preparation certificate, edit the .ini file used to start the Studio:
```
-Djavax.net.ssl.trustStore=/path/to/<trust-store.jks>
-Djavax.net.ssl.trustStorePassword=<trust-store password>
```
When designing your Job in the Studio, connect a tSetKeystore component to the data input component with an OnSubjobOk link in order for the Job to trust the Talend Data Preparation certificate. For more information on how to configure the tSetKeystore, see Talend Components Reference Guide.
