It is impossible to manage of some attributes needed to confiure SSL connection using JMX. Connector section in server.xml file may define truststoreFile, truststorePass, truststoreType attributes to configure SSL connection. But these attributes are not available via JMX interface. First I have found that there is not description of these attributes in (%SRC_ROOT%\container\catalina\src\share\org\apache\catalina\connector\mbeans-descriptors.xml) file. As result these attributes are not available to manage SSL connection using Tomcat Administration Application.
This has been fixed in SVN and will be included in 5.5.21 onwards.
