Apache Tomcat FAQs

Which version of Tomcat do you provide with Linux hosting?
We currently provide version Tomcat version 6.0.24, servlet specification version 2.5, JSP version 2.1.

Is the MySQL JDBC connector already present in the Tomcat instance, or do I have to upload, and if so what location (e.g. tomcat_home/common/lib)?
MySQL JDBC component is installed by default.

Where do I specify context data elements (e.g. tomcat_home/conf/server.xml)?
Server configuration file is located in /etc/tomcat5/server.xml. However, please note that editing this file manually may cause Tomcat to become unstable. Please note that we do not allow customers to edit or read this file.

How can I load additional .jar files to Tomcat_home/common/lib?
If you need to put additional .jar files into server configuration, you need to refer to those components documentation and installation advice. However, in most cases a simple upload of these files to the directory and restart of Tomcat service would suffice.

Is the /lib folder structure supported in tomcat_home/webapps/application_name/WEB-INF, to add application specific .jar files (e.g. tomcat_home/webapps/application_name/WEB-INF/lib/my.jar)?
Application may include its own .jar files and use them. For more information please refer to Tomcat documentation at: http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html.

Do you have any examples of Tomcat and MySQL integration for your hosted platform?
There are no examples in our documentation, however Parallels Plesk does not apply significant changes to Tomcat configuration and does not change object structure, therefore examples provided in standard Tomcat documentation should work without problems.

For instructions on using Tomcat on our Linux hosting, please see the article Add a Java Application Through Tomcat.
