org.eclipse.jst.jsp.core.internal.java.JSPTranslation
An implementation of IJSPTranslation.
This object that holds the java translation of a JSP file as well as a mapping of ranges from the translated Java to the JSP source, and mapping from JSP source back to the translated Java.

You may also use JSPTranslation to do CompilationUnit-esque things such as:
- code select (get java elements for jsp selection)
- reconcile
- get java regions for jsp selection
- get a JSP text edit based on a Java text edit
- determine if a java offset falls within a jsp:useBean range
- determine if a java offset falls within a jsp import statment
