setClassPath

public void setClassPath(java.util.List<java.io.File> path)

Java Compiler options.

setExtdirs

public void setExtdirs(java.lang.String exts)

setSourceVM

public void setSourceVM(java.lang.String sourceVM)

setTargetVM

public void setTargetVM(java.lang.String targetVM)

saveClassFile

public void saveClassFile(java.lang.String className,
                          java.lang.String classFileName)

Save the generated class file to disk, if not already done.

doJavaFile

public void doJavaFile(boolean keep)
                throws JasperException

Remove/save the generated Java File from/to disk

Throws:

JasperException

setDebug

public void setDebug(boolean debug)

getJavaWriter

public java.io.Writer getJavaWriter(java.lang.String javaFileName,
                                    java.lang.String javaEncoding)

Get a Writer for the Java file. The writer is used by JSP compiler. This method allows the Java compiler control where the Java file should be generated so it knows how to handle the input for java compilation accordingly.

getClassLastModified

public long getClassLastModified()

Return the time the class file was generated.

compile

public JavacErrorDetail[] compile(java.lang.String className,
                                  Node.Nodes pageNodes)
                           throws JasperException

Start Java compilation

Parameters:

className - Name of the class under compilation
