Table of contents


This module is one in a collection of modules designed for teaching INEW 2338 Advanced Java (Web) at Austin Community College in Austin, TX. The purpose of this module is to get youstarted writing, deploying, and testing Java servlets.

Servlets, search engines, or JSON

As explained in the page titled Java4510: Preface to INEW 2338 , only one of the topics Search Engines , Servlets , or JSON is covered in the course in any particular semester. However, all three are important. The course material in the Blackboard course management programindicates which topic is covered in the current semester.

Students are encouraged to study all three topics for their own educational purposes in order to enhance their prospects of landing a job as a Java programmer.

Getting started

If you haven't done so already, I strongly recommend that you study the following two modules before continuing with this module:

While studying Java4308 , I recommend that you download, install on your local machine, and test the Apache Tomcat web server. Eventually students enrolled in this course will deploy and test their servlet programs on a web server operated by thecollege. However, the first several modules in this sub-collection will expect students to deploy and test servlets on a local web server.

Viewing tip

I recommend that you open another copy of this module in a separate browser window and use the following links to easily find and view the Figures and Listings while you are reading about them.



General background information

Test for a successful connection on localhost

Assuming that you have properly installed the Tomcat web server on your machine, you should be able to start the server and point your browser to http://localhost:8080/ to see something similar to Figure 1 in your browser.

Figure 1 - Web server test.

Missing Figure

If you don't see that, you should probably rectify the problem before continuing.

While you are there, stop and examine the page showing in your browser window. It is packed with information regarding Tomcat, includingdocumentation and the source code for numerous servlet and JSP examples.

Upgrading your Java development environment

In Java4308 , I showed you how to upgrade your Java development environment to include twojar files named

  • servlet.jar
  • server.jar

I also explained that only the first one may actually be required, but since they are both small, there is no harm in having both of them on your machine.

Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
