Chapter 5 Examples from Java Servlet
Programming
- 5-2: A servlet using persistent connections
- 5-3: Hello, htmlKona
- 5-4: Weather forecast constructed by
hand
- 5-5: Weather forecast using HTML generation
- 5-6: Weather forecast using HTML generation
creatively
- 5-7: Random redirector
- 5-8: The current time, kept current
- 5-9: An explained host change
Examples from other chapters:
- Example 5.2: A servlet using persistent connections
- This servlet enables persistent connections (keep-alive) using
a ByteArrayOutputStream to buffer its output.
- Example 5.3: Hello, htmlKona
- This servlet shows the ubiquitous HelloWorld servlet, rewritten
to take advantage of WebLogic's htmlKona package.
- Try it (disabled, no htmlKona license)
- Source
- Example 5.4: Weather forecast constructed by hand
- This servlet shows a servlet that creates a weather forecast
page without using HTML generation, manually sending its content
wrapped with almost a hundred HTML tags.
- Example 5.5: Weather forecast using HTML generation
- This servlet is Example 5.4 rewritten to use HTML generation.
- Try it (disabled, no htmlKona license)
- Source
- Example 5.6: Weather forecast using HTML generation creatively
- This servlet is Example 5.5 rewritten to use HTML generation
creatively by reusing objects and subclassing.
- Try it (disabled, no htmlKona license)
- Source
- Example 5.7: Random redirector
- This servlet performs a random redirect, sending a client to
a random site selected from its site list. Depending on the site
list, a servlet like this could have many uses. As it stands now,
it's just a jump-off point to a selectino of cool servlet sites.
With a site list containing advertising images, it can be used
to select the next ad banner.
- Example 5.8: The current time, kept current
- This servlet shows a servlet that uses client pull to display
the current time, updated every 10 seconds.
- Example 5.9: An explained host change
- This servlet redirects requests for one host to another host,
giving an exmplanation to the client before the redirection.
