Method Detail

init

public void init(JspCompilationContext ctxt,
                 ErrorDispatcher errDispatcher,
                 boolean suppressLogging)

Initializations

setExtdirs

public void setExtdirs(String exts)

setClassPath

public void setClassPath(List<File> cpath)

Java Compiler options.

getClassLastModified

public long getClassLastModified()

Return the time the class file was generated.

getJavaWriter

public Writer getJavaWriter(String javaFileName,
                            String javaEncoding)
                     throws JasperException

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.

Throws:

JasperException

setDebug

public void setDebug(boolean debug)

setSourceVM

public void setSourceVM(String sourceVM)

setTargetVM

public void setTargetVM(String targetVM)

saveClassFile

public void saveClassFile(String className,
                          String classFileName)

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

doJavaFile

public void doJavaFile(boolean keep)

Remove/save the generated Java File from/to disk

compile

public JavacErrorDetail[] compile(String targetClassName,
                                  Node.Nodes pageNodes)
                           throws JasperException

Start Java compilation

Parameters:

targetClassName - Name of the class under compilation

Throws:

JasperException
