Thank you guys for quick responses.These would be very 
helpful for me.
It 
is definitely possible to build CDT AST based on a JDT one and then use that AST 
to generate code. Please keep in mind though that even very similar C++ and Java 
constructs are represented quite differently in CDT and JDT ASTs. You can take a 
look at CDT refactoring code under org.eclipse.cdt.internal.core.dom.rewrite, 
org.eclipse.cdt/core/org.eclipse.cdt.ui/src/org/eclipse/cdt/internal/corext/refactoring 
and 
org.eclipse.cdt/core/org.eclipse.cdt.ui/src/org/eclipse/cdt/internal/ui/refactoring.

  Hi:
      I have been working with a  eclipse tool which 
  could parse java source file into ast and  translate ast into other 
  programming language(such as c/c++) .And what I just want to know is if there 
  is any possibility to construct a ast manually with the information I get from 
  java ast?If Yes,could you give the example or any references for me to 
  study?
   
  Thax a lot.
