we have created entity that contains five ManyToOne relationship with other field and we are getting all five ManyToOne mapping field ID from UI. Issue is that for insert object we have to make all 'ManyToOne mapping field' in persistent context for same we have to hit DB for five times(five query for get),So for insert one object we have to hit DB six times(five for ManyToOne and one for normal insert).
So,can we create other entity that would contain hardcoded join column name(join column ID is coming from UI) instead of refrence ManyToOne object, only for insert object.It will contain only one query to save object.
Please help me and sorry for english.

Advance Thanks.

P.S. When you post code, make sure that it is properly indented.

public static void main(String[] ar)
{
String s="abc";
String s1="ab";
s1=s1+"c";//why s1 is not created in pool this is also literal
if(s==s1)
System.out.println("equal");
else
System.out.println("unequal");
}
