|  | <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> | ||
|  | <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>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 | ||

|  | 
 | ||
|  | <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> | ||

|  | <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 | ||

|  | <p>To test your application, you will want to install it under Tomcat.  The | ||
|  | quickest way to do that is to use the custom Ant tasks that are included in | ||
|  | the sample <code>build.xml</code> script.  Using these commands might follow | ||
|  | 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> | ||
|  | </ul> | ||
