Securing connections for Talend Dictionary Service

Last updated: 8/28/2025

Procedure

Open the <Tomcat>/conf/server.xml file.

Comment the non-SSL part:

<!-- <Connector port="8187" protocol="HTTP/1.1"
       connectionTimeout="20000"
       redirectPort="8550" /> -->

Uncomment the following lines:

<!-- <Connector port="8550"
protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150"
SSLEnabled="true"
scheme="https"
secure="true"
clientAuth="false"
sslProtocol="TLS"/> -->

Add the following lines:

keystoreFile="<certificate_path>/server.keystore.jks" 
keystorePass="<certificate_password>"

Open the <Tomcat>/conf/data-quality.properties file.

To secure connections with MongoDB, edit the following lines:

dq.mongo.ssl=true
dq.mongo.ssl.trust-store=<path_to_truststore>
dq.mongo.ssl.trust-store-password=<truststore_password>

To secure connections with Kafka using communication encryption only, edit the following lines:

spring.cloud.stream.kafka.binder.configuration.security.protocol=SSL
spring.cloud.stream.kafka.binder.configuration.ssl.truststore.location=<path_to_truststore>
spring.cloud.stream.kafka.binder.configuration.ssl.truststore.password=<truststore_password>

To secure connections with Kafka using authentication, edit the following lines:

spring.cloud.stream.kafka.binder.configuration.ssl.keystore.location=<path_to_keystore>
spring.cloud.stream.kafka.binder.configuration.ssl.keystore.password=<keystore_password>
spring.cloud.stream.kafka.binder.configuration.ssl.key.password=<key_password>

To secure connections with Talend Identity and Access Management, change the below URLs from http to https:
```
oidc.url=https://<iam_url:port>/oidc
scim.url=https://<iam_url:port>/scim
```
Note that the communication encryption parameters must also be defined to use authentication.
