getPageNodespublic org.apache.jasper.compiler.Node.Nodes getPageNodes()Retrieves the parsed nodes of the JSP page, if they are available. May return null. Used in development mode for generating detailed error messages. http://bz.apache.org/bugzilla/show_bug.cgi?id=37062. - Returns:
- the page nodes
 
- 
generateJavaCompile the jsp file into equivalent servlet in .java file- Returns:
- a smap for the current JSP page, if one is generated, null otherwise
- Throws:
- Exception- Error generating Java source
 
- 
generateClassprotected abstract void generateClass(String[] smap) throws FileNotFoundException, JasperException, Exception Servlet compilation. This compiles the generated sources into Servlets.- Parameters:
- smap- The SMAP files for source debugging
- Throws:
- FileNotFoundException- Source files not found
- JasperException- Compilation error
- Exception- Some other error
 
- 
compileCompile the jsp file from the current engine context.- Throws:
- FileNotFoundException- Source files not found
- JasperException- Compilation error
- Exception- Some other error
 
- 
compileCompile the jsp file from the current engine context. As an side- effect, tag files that are referenced by this page are also compiled.- Parameters:
- compileClass- If true, generate both .java and .class file If false, generate only .java file
- Throws:
- FileNotFoundException- Source files not found
- JasperException- Compilation error
- Exception- Some other error
 
- 
compilepublic void compile(boolean compileClass, boolean jspcMode) throws FileNotFoundException, JasperException, Exception Compile the jsp file from the current engine context. As an side- effect, tag files that are referenced by this page are also compiled.- Parameters:
- compileClass- If true, generate both .java and .class file If false, generate only .java file
- jspcMode- true if invoked from JspC, false otherwise
- Throws:
- FileNotFoundException- Source files not found
- JasperException- Compilation error
- Exception- Some other error
 
- 
isOutDatedpublic boolean isOutDated()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.- Returns:
- trueif the source generation and compilation should occur
 
- 
isOutDatedpublic boolean isOutDated(boolean checkClass) 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 dependents, and so on. This method can by overridden by a subclasses of Compiler.- Parameters:
- checkClass- If true, check against .class file, if false, check against .java file.
- Returns:
- trueif the source generation and compilation should occur
 
- 
getErrorDispatcher- Returns:
- the error dispatcher.

- the info about the page under compilation
