servlet womb : Java Glossary

The CurrCon Java Applet displays prices on this web page converted with today’s exchange rates into your local international currency, e.g. Euros, US dollars, Canadian dollars, British Pounds, Indian Rupees… CurrCon requires an up-to-date browser and Java version 1.8, preferably 1.8.0_131. If you can’t see the prices in your local currency, Troubleshoot. Use Firefox for best results.

Servlet womb
aka servlet container, a program than runs on a server on the Internet that hosts Servlets and usually JSP. I also use the term womb more broadly for any class hosting program that serves a similar purpose. They may or may not also handle JSP (Java Server Pages), ASP (Association of Shareware Professionals), PHP (Pre-Hypertext Processor). I prefer the term servlet womb even though its use is not widespread because:
  1. It is more evocative of what it does for Servlets.
  2. Container already has too many overloaded meanings.
  3. The name subtly irritates my arch enemies, the Republicans.
application servers are Servlet wombs with extra features besides handling Servlets, e.g. EJB (Enterprise Java Beans). I also object to the vague term application servers since it could refer to any program at all that runs on a server, not just something that supports Servlets. The problem with my term servlet womb, is that people will look at you funny, even if they know what you mean.

It gets tedious writing Servlets that embed reams of HTML (Hypertext Markup Language) inside Java strings, since your outputs are complete HTML pages. So people have created scores of haire-brained ways of embedding Java code in HTML that gets compiled into the equivalent Java Servlet code dynamically. I find them all to ugly to live. You might have a look at some of the choices of framework.

Notice the huge number of developers who are building JSP clones. In my mind they are all lemmings headed for early extinction. 100% server side computing is a fundamentally flawed concept. I propose something quite different to replace it.

Glass Fish 1.5 1.5 Open source EE from Sun. That 1.5 is not a typo. It supports the upcoming IEEE (Institute of Electrical & Electronics Engineers) 1.5 standard. It is not ready for deployment, but there is code you can run. Last revised/verified: 2006-02-16
HTML Static Macros 1.5 n/a n/a n/a This is a completely different way of dealing with the problem of generating dynamic content. You generate the content before uploading it to a vanilla HTTP server using embedded macros written in Java. The advantage is you require no server side code. Your site can be hosted on any standard HTTP server. It thus serves pages much more efficiently than Servlets do. Everything is already prepared. Caching is more efficient too with true last-modified dates. This is how I generate the content on this website, The approach can be combined with traditional Servlets to handle the mundane pages.

Snigel Seems to have disappeared. A tiny (39K) but fully featured Servlet server, interfaced very similar to Get, post, upload data, sessions, standard logs, public file path, etc. Extended servlet context allows user defined scopes such as static instance, instance-per-thread or even singleton Servlets if one wishes. Especially useful in debugging Servlets.
Sybase EAServer EE, also handles C++, CORBA (Common Object Request Broker Architecture).

If you change the jars used by your JSP code, make sure you manually delete the generated class files (classes in the WEB-INF tree for Caucho Resin). The womb won’t be smart enough to do that on its own and you will get all manner of NoClassDefFound errors.
