   org.apache.jasper.JspCompilationContext

JspCompilationContext
public class JspCompilationContext (Code)
A place holder for various things that are used through out the JSP engine. This is a per-request/per-context data structure. Some of the instance variables are set at different points. Most of the path-related stuff is here - mangling names, versions, dirs, loading resources and dealing with uris.

static Object outputDirLock(Code)




Constructor Detail
JspCompilationContext
public JspCompilationContext(String jspUri, boolean isErrPage, Options options, ServletContext context, JspServletWrapper jsw, JspRuntimeContext rctxt)(Code)



JspCompilationContext
public JspCompilationContext(String tagfile, TagInfo tagInfo, Options options, ServletContext context, JspServletWrapper jsw, JspRuntimeContext rctxt, URL tagFileJarUrl)(Code)




Method Detail
compile
public void compile() throws JasperException, FileNotFoundException(Code)



createCompiler
public Compiler createCompiler() throws JasperException(Code)
Create a "Compiler" object based on some init param data. This is not done yet. Right now we're just hardcoding the actual compilers that are created.



getClassFileName
public String getClassFileName()(Code)



getClassLoader
public ClassLoader getClassLoader()(Code)
What class loader to use for loading classes while compiling this JSP?



getClassPath
public String getClassPath()(Code)
The classpath that is passed off to the Java compiler.



getCompiler
public Compiler getCompiler()(Code)



getContentType

Get the content type of this JSP. Content type includes content type and encoding.



getJavaPath
public String getJavaPath()(Code)
Path of the Java file relative to the work directory.



getJspFile
public String getJspFile()(Code)

getTagFileJarUrls
public Hashtable getTagFileJarUrls()(Code)
Returns the tag-file-name-to-JAR-file map of this compilation unit, which maps tag file names to the JAR files in which the tag files are packaged. The map is populated when parsing the tag-file elements of the TLDs of any imported taglibs.

If the path to the TLD points to a jar file, then thesecond element denotes the name of the TLD entry in the jar file.Returns null if the given uri is not associated with any tag library'exposed' in the web application.
