For security and vulnerability reasons, make sure you apply any current patches from that version of Tomcat.
- Check the version of Apache Tomcat that was bundled within your Talend Data Catalog which is expressed in <TDC_HOME>/TalendDataCatalog/Documentation/License/MIMM-ThirdParty-LICENSES.html and <TDC_HOME>/TalendDataCatalog/tomcat/RELEASE-NOTES.
Download the latest patch version within the same major version.
For more information, see https://tomcat.apache.org/download-90.cgi.
- Unzip the package in a temporary directory.
- Stop Talend Data Catalog (Apache Tomcat) Application Server.
- Copy the lib directory from that temporary directory to <TDC_HOME>/TalendDataCatalog/tomcat/lib, overwriting files if necessary.
- Restart Talend Data Catalog (Apache Tomcat) Application Server.
