As soon as you are ready with template programming, you compile them. Template compilation is managed by org.oomega.generator.JGenC. The command line arguments specify the source directory containing the templates and a destination directory for the resulting Java template files. JGenC processes all files with the suffix ".jgen" in the directory structure specified by source.

<java classname   = "org.oomega.generator.JGenC"
      fork        = "true"
      failonerror = "true"
      classpath   = "etc/:${oomega.home}/lib/oomega-generator.jar:${oomega.home}/lib/oomega-core.jar" >
   <arg line = "-source src/jgen" />
   <arg line = "-dest build/temp/generate/jgen-classes" />
</java>

For a convenient usage within Ant environments, we provide a particular Ant-Task <jgenc>. To make the OOMEGA Ant-Tasks available they have to be included, first:

<taskdef resource="org/oomega/generator/ant/antlib.xml"
         classpath="etc/:${oomega.home}/lib/oomega-generator.jar:${oomega.home}/lib/oomega-core.jar"
/>

Using the OOMEGA Ant-Task, template compilation is done as follows:

<jgenc>
   <source dir="src/jgen" />
   <dest dir="build/temp/generate/jgen-classes" />
</jgenc>

The resulting Java source files are post processed with a standard Java compiler.

<javac srcdir    = "build/temp/generate/jgen-classes/"
       destdir   = "build/temp/templates/"
       debug     = "on"
       encoding  = "UTF-8"
       classpath = "${oomega.home}/lib/oomega-generator.jar:${oomega.home}/lib/oomega-core.jar"
/>
