2D
/ 3D Pie Chart, version 3.2
by Sirius Computer Consultants Limited
Applet
or Servlet
There
are several factors to consider when choosing whether to
implement either the applet or servlet version of the Pie
Chart. The table below highlights some of the most important
points to be taken into account.
| Implementation
Type |
Advantages |
Disadvantages |
| Servlet |
- The
most dependable solution.
- Graph
can be inserted in dynamic HTML with the IMG tag.
- Because
a GIF is generated at the server, it is compatible
with all web browsers.
- Offers
better performance for clients with slower CPUs.
- Usually
less load time on the browser than applets.
|
- Requires
Servlet Engine on the server.
|
| Applet |
- Easy
to install and modify.
- Processing
occurs at the client which offloads the processing
of images from the server.
- Interactive
Graph functionality (eg. display column values on
mouse over, execute url on mouse click.)
- Does
not require any custom modifications to the server.
- The
small size of the JAR files provide quick applet
load times (only 12kb).
|
- Some
browsers do not print applets.
- The
browsers Java VM must be enabled. ( These days this
is usually the case but some people do turn java
off).
|
As
you can see from the table above the big advantage of the
Applet is the interactive features it offers and the big
advantage of the Servlet is the ability to print the graph
image consistently across all browser versions. If both
these factors are important to your implementation then
a combination of the two may be the answer. For an outline
of this solution please see the section
