You may want to add additional features to the web server with your own
servlets. This
document discusses how to do this.
The build process relies on the Ant
build tool from The Jakarta Project.
A build.xml file is included, and the only file you need to modify
for your own configuration is the build.properties file.

Including Your Own Source
The build process allows you to include your own source. You will need
to modify at least two build properties:
src.paths ,
src.files , and possibly
dependency.classpath .
Place the location of the source files in src.paths , and a
list of files in src.files . If your code depends on further
libraries, you may need to modify dependency.classpath as
well. See the build configuration section
for more details.

It is also possible to include your own pre-built classes in the build
process. To do this, add the location of the classes to
dependency.classpath .

Build Configuration — The
build.properties File
The build.properties file is the only place you are required to
manage your build configuration. The syntax requrements are only that a
forward slash (/) for the file separator, and a colon (:) for the path
separator, are used. Also, any non-required properties may be left
unspecified.
Note: If you choose to use backslashes
(\) for your paths, say, in Windows, then you must use pairs (eg.
src.paths=C:\\Projects\\MySource). This is
because in properties files, backslashes are treated specially. They
act to change the meaning of the following character. Please consult
the Java documentation for more information.
cdc.classes
This property should point to the core CDC classes for your
environment. Leave it unspecified to use the default JDK classes.
src.paths
This points to the location(s) of your source files. For example:
src.paths=mysrc:myservlets/src
A path separator is used between different paths.
src.files
A comma- or space-separated list of source files. This may be specified
using Ant-style wildcard
patterns. For example:
src.files=com/mycompany/util/*.java,com/theircompany/**/*.java
It is not a good idea to specify **/*.java since that may
include unwanted source files. Instead, be more specific with the package
structure, as in the above example.
dependency.classpath
This specifies a CLASSPATH-like list of paths and archives containing
any classes needed by your source files. For example:
dependency.classpath=mymodules.jar
target.jar
This names the JAR file that will be created from any compiled source
code that was specified with src.files . If not
specified, then the default will be "myclasses.jar".
This should not contain extra path information. For example:
target.jar=mylib.jar
These are incorrect: target.jar=path/mylib.jar
or target.jar=/root/path/mylib.jar.
This file will be included by the deploy script.
One additional step you must do is prepend this file to the
'-classpath' setting inside the WebServer script in the
bin/ directory. This will enable the virtual machine to find
your classes.

Other Build-Related Files
This section discusses the other files needed in the build process.
The build.xml file
The build.xml file is the Ant build script. Its default task
will automatically compile your source files and archive them into a JAR
file in the bin/ directory.
By default, all compiled classes will be written to a directory named
classes/. This can be changed by changing the
javac.destination property to something else.
