A little oversight that may happen when configuring the apache2 server to work with bluedragon is the correct assignment of the .cfchart file extension. Without this option the <cfchart> tag will appear to be broken.
A working bluedragon7 configuration section from the apache configuration file looks like this:
# BlueDragon 7 JX LoadModule servletexec_module /usr/lib/apache2/modules/mod_servletexec22.so ServletExecInstances default 127.0.0.1:9999 ServletExecAliases default /servlet .cfc .cfm .cfml .cfchart <location /servlet> SetHandler servlet-exec </location> AddHandler servlet-exec cfc AddHandler servlet-exec cfm AddHandler servlet-exec cfml AddHandler servlet-exec cfchart ddHandler servlet-exec cfml
