doJavaFile

public void doJavaFile(boolean keep)
                throws JasperException

Remove/save the generated Java File from/to disk

Throws:

JasperException

setDebug

                                  Node.Nodes pageNodes)
                           throws JasperException

Start Java compilation

Parameters:

className - Name of the class under compilation

Throws:

JasperException
