How to get a parent node reference in JXPath??

[john sal]

Can someone let me know how can i retrieve parent node context in jxpath.

For Example:

  class Class1{
	int id = 1;
	int type  = 2;
	static class Class2{
		String value ="value";
		Class3 c3 = new Class3();
		  
		
	}
}

public class TestDemo {
   public static void main(String args[]){
      Class1 c1 = new Class1();
       Class1.Class2 c2 = new Class1.Class2();
       JXPathContext context =JXPathContext.newContext(c2.c3);
    	
       Pointer p = context.getPointer(".");
       JXPathContext relativeContext = context.getRelativeContext(p);

     //I got the context of class c3 now using this context i want to get reference of Class2
      	
   }

  public class Class3 {
     public int type = 4;
     public String id = "one";
  }
}  

I got the context of class c3 now using this context i want to get reference of Class2.
Can someone let me know how can i get the same?
