Description copied from interface: JavaCompiler

Start Java compilation

Specified by:

compile in interface JavaCompiler

Parameters:

className - Name of the class under compilation

Throws:

JasperException

doJavaFile

public void doJavaFile(boolean keep)

Description copied from interface: JavaCompiler

Remove/save the generated Java File from/to disk

Specified by:

doJavaFile in interface JavaCompiler
