| Overview |
|
The
iSeries, backed by a strong development commitment from IBM, has emerged
as a world-class e-server. The programming skills required to stay
apace with this development have radically changed as well. WebSphere
is an essential part of this new dynamic and a working knowledge of
Java is an essential element for iSeries web development success with
WebSphere.
Practical Java Programming for WebSphere is a proven, highly
effective self-paced training course for learning Java, JDBC, servlet
and JSP programming at your site.
The course assumes no prior knowledge of Java, WebSphere or web development
and provides a comprehensive introduction to these programming skills.
When done, you will have created several functional examples of data-driven
web pages and gained a working knowledge of Java.
The training emphasis is on creating working programs to access, display
and change data. Unlike other Java courses, there are no hypothetical
examples or theoretical discourses. Everything in the training can
be put to immediate use by iSeries programming professionals. The
course is an excellent introduction to modern, cross-platform programming
technologies.
"The
course assumes no prior knowledge of Java, WebSphere or web development
and provides a comprehensive introduction to these programming skills." |

|
| "Hello
World" |
|
Work
with Java projects, Java packages and classes, and code editing
features. Create a first Java class and also the Javadoc documentation
for it. You'll learn how to use "SmartGuides" to help
create Java code and the relationships between projects, packages,
classes and methods.
You'll
also learn about package naming conventions and Java naming conventions.
You'll use VisualAge for Java features to quickly create a class,
and learn how to navigate the Java development environment. When
done, you will have created and run a class (program) in the Java
environment and painlessly created documentation for it. |
| |
|
|
Using
JDBC for
Database Access |
|
Create
Java classes to access the database using SQL statements in JDBC.
Also learn about Java exceptions, Console I/O and the Debugger. You'll
learn how to set the Classpath, how to code and work with Prepared
Statements, and how SQL and JDBC errors are reported to your methods.
You also learn how to work with Java import statements and how to
identify and work with JDBC driver classes. You will work with the
AS/400 JDBC driver or the Sun JDBC-ODBC driver to access the test
database on the iSeries or on your PC. |
| |
|
|
Basic
HTML
for web forms |
|
Work
with a sample web form on the CD-ROM provided with the course and
identify the HTML elements used on the form. All of the important
HTML form elements are shown in illustrations and code, along with
tips and "best practice" advice for using the elements.
This section also describes how to use HTML tables for formatting
your web page displays, and includes an extensive discussion and example
of using links in the <a href> tag. It also describes how the
<form> tag is used to group HTML form elements together to send
them to a servlet or JSP for processing. |
| |
|
|
| JavaScript |
|
Review
the JavaScript code in the sample Ship-to HTML web form and understand
how form fields are edited at the browser. An illustrated and annotated
code sample is described so that you can see exactly how web form
fields can be edited and error messages conveyed to the user.
The
chapter discusses some of the cross-browser issues you will encounter
and how to use JavaScript functions to detect the user's browser.
The Netscape FormChek.js file is described, and several functions
in it are used in the code sample. |
| |
|
|
Cascading
Style Sheets |
|
Examine
how Cascading Style Sheet files are used with the web form to control
the appearance of form elements, and how CSS helps standardize your
web forms' appearance. Several web form illustrations and code are
shown, along with descriptions of how the CSS features are used in
the HTML code.
The CSS element, class and id selectors are described and illustrated
so that you will know how to have complete control over CSS features
with your HTML code.
|
| |
|
|
Using
the
WebSphere Test
Environment |
|
Learn
to work with the WebSphere Test Environment to serve HTML files, servlets
and JavaServer Pages on your PC. The WTE provides a robust simulation
of WebSphere Application Server. You'll learn about the Document Root
Directory, how to configure your browser to access the WTE, and serve
a sample HTML and JSP file.
You'll learn how to set the Classpath for the WTE, how to start and
end the WTE, and how to monitor its activities in the Console. You'll
also load and use the sample web page to verify the WTE operation.
When testing your JSP file, you'll see how the JSP Execution Monitor
is used to track the execution of a JSP. |
| |
|
|
Create
and
run servlets |
|
Create
servlets based on the JDBC samples to access a database and display
web inquiry pages. Also learn how to configure and work with datasources
and connection pools. You'll learn how to throw exceptions in your
code, how to retrieve initialization values, and how to pass parameters
from an HTML form to a servlet.
You'll see how to put debugging code into a servlet so you can easily
track its execution, and you'll work with the Persistent Name Server
in the WTE to configure datasources. You'll also learn how to intercept
invalid HTML form values and set them to reasonable defaults in your
servlet. |
| |
|
|
Create and test
JavaServer Pages |
|
Code
several JavaServer Pages to display and alter data. Work with the
JSP Execution Monitor to debug JSPs. Also learn how the WebSphere
JSP tags simplify JSP coding. You'll create a "subfile"
JSP to display queried data and learn how to work with session variables
to pass data from JSP to JSP.
You'll learn how to work with directives, scriptlets, declarations
and expressions, and convert your JDBC and servlet examples to the
equivalent JSP samples. You'll also test an HTML form and JSP that
inserts new rows into a table, then create JSPs to update and delete
table data. |

A PC
with a Pentium 233 processor or better with at least 128MB of RAM
and about 500MB of available disk space is required. Windows 98, Windows
ME, Windows NT 4.0, Windows 2000, or Windows XP may be used. You can
use a stand-alone copy of VisualAge for Java or use the version that
is packaged with the new WebSphere Development Tools for iSeries.
The training uses the Professional Edition of VisualAge for Java,
which contains all the tools you need to create full-featured WebSphere
applications.
There is no need to have WebSphere Application Server (WAS) installed
on your AS/400. VisualAge for Java contains a built-in WebSphere Test
Environment that mimics WAS, so you can develop and test everything
on your PC. If you do have WAS running on your AS/400, you can export
your code and run it there. As you develop your code, you can use
the AS/400 Toolbox for Java JDBC driver to access the AS/400 database,
or you can use a local database on your PC. All of the code and examples
are oriented towards AS/400 work, and will run, unchanged, when exported
from your PC to your AS/400. |

Frequently
Asked Questions |
Important Points |
|
Why
does the course use VisualAge for Java?
For
two reasons: VisualAge for Java is currently the best development
tool to illustrate the Java fundamentals taught in the course; and
IBM provides it to iSeries customers in the WebSphere Development
Tools for iSeries shipped with OS/400 upgrades.
Will the skills gained from this training be transferable to
the new WebSphere Studio Application Developer?
Yes.
You will be able to immediately use all of the skills developed
with Practical Java Programming for WebSphere. In short,
you can use the tools you have today to learn the skills you will
need tomorrow.
What
programming proficiency level is necessary to successfully complete
the course?
The
course assumes that you are an experienced RPG or COBOL programmer.
You do not need to know any Java or web programming before starting,
as those skills are developed in the course.
Do I need access to the AS/400 to take this training?
No.
You can complete all the training using only your PC. However, if
you have access to an AS/400, you can upload a test file to it.
You can also use a test PC database file to simulate access to the
AS/400. You do not need WebSphere installed on your AS/400 since
you can do all of your web testing on your PC using the WebSphere
Test Environment.
How long does the course take?
The
course can be completed in a week. If you already have some Java
or web programming experience you will be able to complete the course
quicker.
