ANT to compile report that use a helper class

2003-10-16 13:59

Hi List,

 

I am using the JasperReports ANT task to compile a report design that uses a custom helper class in one of its expressions.

 

This is my ANT script:

---------------------------------------------

<taskdef name="jrc" classname="dori.jasper.ant.JRAntCompileTask">

<classpath>

<pathelement location="${jasper.root.dir}/lib/jasperreports-0.5.0.jar"/>

</classpath>

</taskdef>

<target name="compile-helpers">

<!-- Compile Helper Classes-->

<javac srcdir="${jasper.helpers.source}" destdir="${jasper.compiledhelpers.dir}" classpath="${jasper.root.dir}/lib/jasperreports-0.5.0.jar"/>

<jar jarfile="${jasper.root.dir}/lib/jasperHelpers.jar"><fileset dir="${jasper.compiledhelpers.dir}" includes="**/*.class"/></jar>

</target>

<target name="compile-reports" depends="compile-helpers">

<!-- Compile Reports -->

<jrc srcdir="${jasper.source.dir}" destdir="${jasper.compiledreports.dir}">

<classpath><fileset dir="${jasper.root.dir}/lib"><include name="*.jar"/></fileset></classpath>

</jrc>

</target>

--------------------------------------------

But I get a stacktrace that seems to be complaining about not being able to find the helper class.

Any suggestions welcome.

 

Thanks,

Santosh
