Tutorials for Eclipse & Web Tools

Using the Flash tutorials

Most of the tutorials on this page are Flash presentations. Generally the tutorials just show you how to do something, only occasionally pausing to give you extra information in a pop-up dialog. To continue the tutorial after this point, click the next button (which is usually found at the bottom of the page). Note that at any time you can pause and/or rewind (click anywhere on the presentation timeline) the presentation using the controls at the bottom of the page.

Eclipse 3.2, WTP 1.5 and Tomcat 4.1

a. Tomcat Setup (when working from an undergraduate lab)

Ensure that your Unix account has sufficient quota (unfortunately at this point I'm unsure how much room is needed; but take this opportunity to clean out your account of unneeded files :).
Login to a Linux workstation.
Somewhere under your account, create a directory named, "wea":
```
cd <to-where-you-want-the-dir-to-reside>
mkdir wea
cd wea
```
Copy tomcat41.tar to your wea directory and untar it:
```
tar xf tomcat41.tar
```
You should now see a subdirectory named tomcat41. If this is the case then you can delete the tar file.

b. Eclipse WEA Configuration

Launch Eclipse 3.2. In our undergraduate labs you need to execute

eclipse_se &
from a shell.

If this is the first time your are running WTP 1.5 under Eclipse 3.2, select a new workspace to work from: e.g.

wea/eclipse32

Ensure that Eclipse is configured to a Java SDK (rather than only a JRE). The path to the SDK that you will need is:

/encs/pkg/j2sdk-1.5.0/root

c. Run some tests ...

Test Tomcat by creating and viewing "Hello Web" static and dynamic pages. Follow these steps:

Build a Dynamic Web Project.
Create and view a static HTML page.
Create greeting servlet and view its output. (The demo also shows a common error and how to deal with it.)
Here is the code you will be using during this step:
```
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("Hello web (from the servlet)!");
out.close();
```

Finishing up

Once you are done:

Stop Tomcat: from the J2EE perspective, select the "Servers" tab; right-click on the Tomcat server and select stop.
Exit Eclipse.
