<p>Although application development can take many forms, this manual proposes
|
|
a fairly generic process for creating web applications using Tomcat. The
|
|
following sections highlight the commands and tasks that you, as the developer
|
|
of the code, will perform. The same basic approach works when you have
|
|
multiple programmers involved, as long as you have an appropriate source code
|
|
control system and internal team rules about who is working on what parts
|
|
of the application at any given time.</p>
|
|
|
|
<p>The task descriptions below assume that you will be using CVS for source
|
|
code control, and that you have already configured access to the appropriate
|
|
CVS repository. Instructions for doing this are beyond the scope of this
|
|
manual. If you are using a different source code control environment, you
|
|
will need to figure out the corresponding commands for your system.</p>

<p>In order to take advantage of the special Ant tasks that interact with the
|
|
<em>Manager</em> web application, you need to perform the following tasks
|
|
once (no matter how many web applications you plan to develop).</p>
|
|
<ul>
|
|
<li><em>Configure the Ant custom tasks</em>. The implementation code for the
|
|
Ant custom tasks is in a JAR file named
|
|
<code>$CATALINA_HOME/server/lib/catalina-ant.jar</code>, which must be
|
|
copied in to the <code>lib</code> directory of your Ant installation.
|
|
<br><br></li>
|
|
<li><em>Define one or more Tomcat users</em>. The <em>Manager</em> web
|
|
application runs under a security constraint that requires a user to be
|
|
logged in, and have the security role <code>manager</code> assigned to
|
|
him or her. How such users are defined depends on which Realm you have
|
|
configured in Tomcat's <code>conf/server.xml</code> file -- see the
|
|
<a href="../../realm-howto.html">Realm Configuration HOW-TO</a> for more
|
|
information. You may define any number of users (with any username
|
|
and password that you like) with the <code>manager</code> role.

|
|
<p>The first step is to create a new project source directory, and customize
|
|
the <code>build.xml</code> and <code>build.properties</code> files you will

be using. The directory structure is described in <a href="source.html">the
|

previous section</a>, or you can use the
|
|
<a href="../sample/">sample application</a> as a starting point.</p>
|
|
|
|
<p>Create your project source directory, and define it within your CVS
|
|
repository. This might be done by a series of commands like this, where
|
|
<code>{project}</code> is the name under which your project should be
|
|
stored in the CVS repository, and {username} is your login username:</p>

|
|
<p>Next, you will need to create and check in an initial version of the
|
|
<code>build.xml</code> script to be used for development. For getting
|
|
started quickly and easily, base your <code>build.xml</code> on the
|
|
<a href="build.xml.txt">basic build.xml file</a>, included with this manual,

or code it from scratch.</p>

|
|
<p>Until you perform the CVS commit, your changes are local to your own
|
|
development directory. Committing makes those changes visible to other
|
|
developers on your team that are sharing the same CVS repository.</p>
|
|
|
|
<p>The next step is to customize the Ant <em>properties</em> that are
|
|
named in the <code>build.xml</code> script. This is done by creating a
|
|
file named <code>build.properties</code> in your project's top-level
|
|
directory. The supported properties are listed in the comments inside
|
|
the sample <code>build.xml</code> script. At a minimum, you will generally
|
|
need to define the <code>catalina.home</code> property defining where
|
|
Tomcat 5 is installed, and the manager application username and password.
|
|
You might end up with something like this:</p>

<p>In general, you will <strong>not</strong> want to check the

is unique to each developer's environment.</p>

<p>The edit/build/test tasks will generally be your most common activities
|
|
during development and maintenance. The following general principles apply.
|
|
As described in <a href="source.html">Source Organization</a>, newly created
|
|
source files should be located in the appropriate subdirectory, under your
|
|
project source directory.</p>
|
|
|
|
<p>Whenever you wish to refresh your development directory to reflect the
|
|
work performed by other developers, you will ask CVS to do it for you:</p>

|
|
|
|
<p>To create a new file, go to the appropriate directory, create the file,
|
|
and register it with CVS. When you are satisfied with it's contents (after
|
|
building and testing is successful), commit the new file to the repository.
|
|
For example, to create a new JSP page:</p>
|
|
<div align="left"><table cellspacing="4" cellpadding="0" border="0"><tr><td bgcolor="#023264" width="1" height="1"><img src="../../images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" height="1"><img src="../../images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" width="1" height="1"><img src="../../images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td></tr><tr><td bgcolor="#023264" width="1"><img src="../../images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#ffffff" height="1"><pre>

|
|
|
|
<p>Java source code that is defined in packages must be organized in a
|
|
directory hierarchy (under the <strong>src/</strong> subdirectory) that
|
|
matches the package names. For example, a Java class named
|
|
<code>com.mycompany.mypackage.MyClass.java</code> should be stored in file
|
|
<code>src/com/mycompany/mypackage/MyClass.java</code>.
|
|
Whenever you create a new subdirectory, don't forget to
|
|
register it with CVS.</p>
|
|
|
|
<p>To edit an existing source file, you will generally just start editing
|
|
and testing, then commit the changed file when everything works. Although
|
|
CVS can be configured to required you to "check out" or "lock" a file you
|
|
are going to be modifying, this is generally not used.</p>

a pattern like this:</p>
|
|
<ul>
|
|
<li><em>Start Tomcat 5 if needed</em>. If Tomcat 5 is not already running,
|
|
you will need to start it in the usual way.
|
|
<br><br></li>
|
|
<li><em>Compile your application</em>. Use the <code>ant compile</code>
|
|
command (or just <code>ant</code>, since this is the default). Make
|
|
sure that there are no compilation errors.
|
|
<br><br></li>
|
|
<li><em>Install the application</em>. Use the <code>ant install</code>
|
|
command. This tells Tomcat to immediately start running your app on
|
|
the context path defined in the <code>app.path</code> build property.
|
|
Tomcat does <strong>NOT</strong> have to be restarted for this to
|
|
take effect.<br><br></li>
|
|
<li><em>Test the application</em>. Using your browser or other testing
|
|
tools, test the functionality of your application.
|
|
<br><br></li>
|
|
<li><em>Modify and rebuild as needed</em>. As you discover that changes
|
|
are required, make those changes in the original <strong>source</strong>
|
|
files, not in the output build directory, and re-issue the
|
|
<code>ant compile</code> command. This ensures that your changes will
|
|
be available to be saved (via <code>cvs commit</code>) later on --
|
|
the output build directory is deleted and recreated as necessary.
|
|
<br><br></li>
|
|
<li><em>Reload the application</em>. Tomcat will recognize changes in
|
|
JSP pages automatically, but it will continue to use the old versions
|
|
of any servlet or JavaBean classes until the application is reloaded.
|
|
You can trigger this by executing the <code>ant reload</code> command.
|
|
<br><br></li>
|
|
<li><em>Remove the application when you re done</em>. When you are through
|
|
working on this application, you can remove it from live execution by
|
|
running the <code>ant remove</code> command.</li>
|
|
</ul>
|
|
|
|
<p>Do not forget to commit your changes to the source code repository when
|
|
you have completed your testing!</p>

|
<p>When you are through adding new functionality, and you've tested everything
|
|
(you DO test, don't you :-), it is time to create the distributable version
|
|
of your web application that can be deployed on the production server. The
|
|
following general steps are required:</p>
|
|
<ul>
|
|
<li>Issue the command <code>ant all</code> from the project source
|
|
directory, to rebuild everything from scratch one last time.
|
|
<br><br></li>
|
|
<li>Use the <code>cvs tag</code> command to create an identifier for
|
|
all of the source files utilized to create this release. This allows
|
|
you to reliably reconstruct a release (from sources) at a later
|
|
time.</li>
|
|
<li>Issue the command <code>ant dist</code> to create a distributable
|
|
web application archive (WAR) file, as well as a JAR file containing
|
|
the corresponding source code.
|
|
<br><br></li>
|
|
<li>Package the contents of the <code>dist</code> directory using the
|
|
<strong>tar</strong> or <strong>zip</strong> utility, according to
|
|
the standard release procedures used by your organization.</li>
