public Jsr199JavaCompiler()

方法详细信息

init

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

Initializations

release

public void release()

Release resouces used in the current compilation

setClassPath

public void setClassPath(List<File> path)

Java Compiler options.

setExtdirs

public void setExtdirs(String exts)

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)
                throws JasperException

Remove/save the generated Java File from/to disk

抛出：

JasperException

setDebug

public void setDebug(boolean debug)

getJavaWriter

public Writer getJavaWriter(String javaFileName,
                            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(String className,
                                  Node.Nodes pageNodes)
                           throws JasperException

Start Java compilation

参数：

className - Name of the class under compilation

抛出：

JasperException
