<h2><a name="introduction"></a>Introduction</h2>
Visual Age for Java is a great Java IDE, but it lacks decent
build support; for creating deliveries. On the other hand,
Ant supports the build process very good, but is
(at least at the moment) command line based. So we decided
to write some tasks to access the VAJ repository and
a small visual Ant frontend to make running Ant from VAJ possible.
We use the Tool API to integrate Ant in VisualAge for Java.
In combination  with the VAJ tasks (vajload, vajexport, vajimport)
you can load defined defined  versions of projects into your workspace,
export the source code, compile it with an external compiler
and build a jar without leaving the IDE. Of course compile
messages are viewed in a logging window. Concluding: This
tool provides decent deployment support VAJ has not (out of the box).<br>

<h2><a name="tasks"></a>The Tasks</h2>
At the moment there are three tasks which help integrating the VAJ repository
contents into an external build process:

<table cellpadding="2" cellspacing="2" border="0" width="500">
   <tbody>
     <tr valign="Top">
       <td valign="Top"><a href="#vajload">VAJLoad</a><br>
       </td>
       <td valign="Top"> loads specified versions into the workspace<br>
       </td>
     </tr>
     <tr valign="Top">
       <td valign="Top"><a href="#vajexport">VAJExport</a><br>
       </td>
       <td valign="Top"> exports specified packages into the file system<br>
       </td>
     </tr>
     <tr valign="Top">
       <td valign="Top"><a href="#vajimport">VAJImport</a><br>
       </td>
       <td valign="Top"> imports specified files into the workspace<br>
       </td>
     </tr>
  </tbody>
</table>
These tasks are described in detail below.

<h3>Description:</h3>
<p>Exports Java source files, class files and/or resources from the workspace
to the file system. Exports can be specified by giving the VAJ project
name and package name(s). This works very similar to <a href="index.html#fileset">
FileSets</a>. </p>

</pre>
This example imports all class files in the directory ${import.dir}/com/sample
excluding those in the subdirectory test<br>

<hr>
<h2><a name="sample_buildfile"></a>A sample build file</h2>
This is a sample build file which builds a zip file useful for distribution
of the VAJ plugin. The build file exports a specific version of Ant, compiles
it, extracts necessary helper classes and zips everything together. This
is useful as complete example as well as to deploy Ant in a team where all
developers use VAJ. The resulting zip file must be unzipped in
<tt>&lt;VAJInstallDir&gt;\ide\tools\org-apache-tools-ant</tt>.

<h2><a name="plugin"></a>The Plugin</h2>
The tasks are usable within VAJ by running the
org.apache.tools.ant.Main class, but this is
quite inconvenient. Therefore a small GUI is
provided which allows selecting a build file
and executing its targets. This Plugin is accessible
from the VAJ Tools menu (see <a href="#usage">Usage</a>).

<hr>
<h2><a name="installation"></a>Installation</h2>
At the moment the installation has it's rough edges. If something
described below doesn't work for You, it's probably not Your fault
but incomplete/wrong instructions. In this case, please contact one
of the <a href="#authors">authors</a>.
We assume <font face="Courier">C:\IBMVJava</font> as VAJ install
directory. If You have installed it elsewhere, adapt the pathes below.
Execute following steps to get the PlugIn up and running:
<ul>
  <li>install the Visual Age IDE Tools (via File-&gt;Quick Start-&gt;
      Add feature-&gt;'IBM IDE Utility class libraries'
  </li>
  <li>import an appropriate XML parser to VAJ (we use Xerces 1.2.0 and are
      happy with it). Unfortunately the XML parser delivered with VAJ (in
      the project 'IBM XML Parser for Java') doesn't work with Ant. You have to
      remove that project (temporarily) from the workspace before importing another
      XML implementation.
  </li>

  <li>import the Ant sources into VAJ.</li>
  <li>Create the directory <font face="Courier">
      C:\IBMVJava\ide\tools\org-apache-tools-ant</font>.
  </li>
  <li>export the Ant and XML parser class files into this directory. Be sure
      to select class files and resources. Sources don't have to be exported.
      Some optional tasks have errors and can't be exported when You
      don't have the necessary packages in Your workspace (e.g. junit
      task, ejbc task). If You need this tasks either import these packages
      into VAJ, too, or copy the .class files directly from the binary
      distribution.
  </li>
  <li>copy <font face="Courier">default.ini</font> (in <font face="Courier">
      jakarta-ant\src\...\taskdefs\optional\ide</font>)     to <font face="Courier">
      C:\IBMVJava\ide\tools\org-apache-tools-ant\default.ini</font>.
  </li>
  <li>if you want to access this help from the Workbench, create the
      directory <font face="Courier"> C:\IBMVJava\ide\tools\org-apache-tools-ant\doc</font>
      and copy the files     <font face="Courier">VAJAntTool.html</font>,
      <font face="Courier">toolmenu.gif</font> and     <font face="Courier">
      anttool1.gif</font> to it.
  </li>
  <li>VAJ has to be restarted to recognize the new tool.</li>
  <li>Now if You open the context menu of a project, You should see the entry
     'Ant Build' in the Tools submenu (see <a href="#usage">Usage</a>).
  </li>
  <li>Make sure the tool works as expected. Now You can remove Ant and the
      imported XML parser from Your workspace (and optionally add the
      IBM parser again).
  </li>
</ul>

<hr>
<h2><a name="usage"></a>Usage</h2>
Beeing sure the tool is installed correctly and your Ant build
file is configured, it is really easy to use.<br>
Go to your Workbench, select the project you want to deploy and
open its context menu. In the submenu <i>Tools</i> you should find
the new entry <i>Ant Build</i>. Klick it to start the tool!

<center><img src="toolmenu.gif" border="0" height="246" width="393"></center>
           After a short time this frame should pop up:
<center><img src="anttool1.gif" border="0" height="222" width="389"></center>
           This frame contains the following elements:
<ul>
  <li>A menubar with some options described later</li>
  <li>The name of your selected VAJ project</li>
  <li>An entry field for the Ant XML buildfile with a browse [...] button.
      The full qualified filename, including the directory is needed here.
  </li>
  <li>A list with tasks specified in the buildfile. Until your first save
      of the build info (described later), this list will be empty. When
      loading a build file by the <i>Reload Project</i> button, this list
      is filled with all tasks which have a description attribute. The
      task you select in this list will be executed when pressing the
      <i> Execute Task</i> button.
  </li>
  <li>A pulldown box for specifying the log level.</li>
  <li>Three buttons. Two of them I have already described and the third one
      is just the <i>Close </i>button to exit our small tool!
  </li>
</ul>
After you have set up your buildprocess you might find it useful
to save the data you've just entered, so we implemented an option to
save it to the  repository into your selected project. Make sure that you
have an open edition of your project before selecting
<i>Save BuildInfo To Repository</i> from  the <i>File</i> menu.
Now your information is saved to this edition of your  project and will
be loaded automatically the next time you start <i>Ant Build</i>.<br>
If you have closed the log window accidentally, it can be reopened
with the <i>Log</i> item in the <i>File</i> menu, and if you want to
know who developed this, just select <i>About</i> in the <i>Help</i> menu.

<h2><a name="faq"></a>Frequently Asked Questions</h2>

<p><b>Q: I want to load, export and build more then one Visual Age project
to one jar! How to?</b><br>
A: The VA tasks are able to load and export several Projects all
at once. You can choose whatever project you like for storing the tool
information, it doesn't really matter
</p>
<p><b>Q: When I load my build file, the list of targets is empty. Why?</b><br>
A: You need to add the optional "description" parameter to the targets You
want to come up in the list. Then reload the build file in the "ant build"
tool. We chose to display only targets with description to allow the build
file developer to distinguish between targets for end users and helper targets.
</p>
<p><b>Q: Is there a sample build file available? </b><br>
A: Now You can find an <a href="#sample_buildfile">example</a> in this manual
</p>

<p><b>Q: Why does it export my entire workspace when I've already implicitly
selected a project when starting the Tool?</b><br>
A: This selection does not carry into the buildfile you are using. Set the
Project name at the beginning of the "includes" parameter.
</p>
<p><b>Q: When I import Ant into my Workspace, I get Problems reported. Can I
ignore them?</b><br>
A: It depends on the problems reported, and what you want to do with Ant.
Problems you can't ignore:
<ul>
  <li>Classes from javax.xml.parser missing - install a compatible parser
      (see <a href="#installation">installation</a>)
  </li>
  <li>Classes from com.ibm.ivj.util missing - install the Visual Age IDE
      Utility feature  (see <a href="#installation">installation</a>).
  </li>
</ul>
</p>

<p><b>Q: Why is the task name vajload when the class is called VAJLoadProjects?</b><br>
A: At the moment this task can load only project versions. This is reflected
by the class name. It may be extended to load package and class versions,
too, and we didn't want to let these extensions affect the build files. Therefore
we chose the more general name vajload as task name.
</p>
<p><b>Q: I want to use the same buildfile both within Visual Age and from the
command line using my regular Ant environment. What do I need to be aware
of?</b><br>
A: The three Visual Age Tasks won't work when executing Ant from the command
line.
</p>
<p><b>Q: How do I control the import/export of sourcefiles, compiled files and
project resources explicity?</b><br>
A: Via the Boolean values exportClasses (default false) exportSources (default
true) and exportResources (default true). In some situations, Resources are
not exported correctly without this being explicity set.

<h2><a name="known_problems"></a>Known Problems</h2>
<ul>
  <li>Exporting a package containing just resources doesn't work. This is
      a VAJ Tool API bug. Workaround: create a dummy class and set 'exportSources'
      to false.
  </li>
</ul>

<h2><a name="va_versions"></a>VisualAge for Java Versions</h2>
This tool integration has been tested with versions 3.02 and 3.5
of VisualAge for Java. It should run with the 2.x Versions, too, but
we didn't try. The graphical user interface is build with AWT so it is
JDK independent by now.
