Compile the servlet from .java file to .class file



generateJava
protected String[] generateJava() throws Exception(Code)
Compile the jsp file into equivalent servlet in .java file a smap for the current JSP page, if one is generated, nullotherwise



getCompilationContext
public JspCompilationContext getCompilationContext()(Code)



getErrorDispatcher
public ErrorDispatcher getErrorDispatcher()(Code)
Gets the error dispatcher.



getPageInfo
public PageInfo getPageInfo()(Code)
Gets the info about the page under compilation



getPageNodes
public Node.Nodes getPageNodes()(Code)

init
public void init(JspCompilationContext ctxt, JspServletWrapper jsw)(Code)



isOutDated
public boolean isOutDated()(Code)
This is a protected method intended to be overridden by subclasses of Compiler. This is used by the compile method to do all the compilation.



isOutDated
public boolean isOutDated(boolean checkClass)(Code)
Determine if a compilation is necessary by checking the time stamp of the JSP page with that of the corresponding .class or .java file. If the page has dependencies, the check is also extended to its dependeants, and so on. This method can by overidden by a subclasses of Compiler.
Parameters:
  checkClass - If true, check against .class file, if false, check against.java file.
