Getting the value of a Local Variable.

Question

How do I make a local variable available
to a method in the same class so that
this local variable can be available
to any class?
public class CheckDetailRowsIterate extends TagSupport
     public int doStartTag() throws JspException
        Row currentRow = null;
        RowsetIterateTag detailIterator = (RowsetIterateTag)TagSupport.findAncestorWithClass(this, RowsetIterateTag.class);
        currentRow = detailIterator.getRow();
     // How do I return back the currentRow?
     public Row getCR(){
]

Answer 1

You don't need a member variable, you can use a parameter to pass a variable.
However in your case, you can just put the code for getting a currentRow into the getCR() method
e.g.
public class CheckDetailRowsIterate extends TagSupport {
     public int doStartTag() throws JspException  {
          Row currentRow = getCR();
     // How do I return back the currentRow?
     public Row getCR(){
        RowsetIterateTag detailIterator = (RowsetIterateTag)TagSupport.findAncestorWithClass(this, RowsetIterateTag.class);
        return detailIterator.getRow();
}
