Class JDTJavaCompiler

    java.lang.Object
      org.apache.jasper.compiler.JDTJavaCompiler

    public class JDTJavaCompiler

extends Object

JDT class compiler. This compiler will load source dependencies from the context classloader, reducing dramatically disk access during the compilation process.

Constructor Detail

### JDTJavaCompiler

    public JDTJavaCompiler()

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`
