Hello,

I want to add a custom tag to my application so it will be more
mainatable.
Let's say I have some tree like structure that can be used like that in
a scriptlet:

AndOrTree t = new AndOrTree();
       t.addCondition("1","eq","cpu-time","5");
       t.addCondition("2","eq","size","8");
       t.addAccumulator("3","1","2",AndOrTree.ACCUMULATOR.AND);
       t.addCondition("4","eq","fullscans","0");
       t.addAccumulator("5","3","4",AndOrTree.ACCUMULATOR.OR);
       out.print(t.toString());

The addCondition and addAccumulator functions take as a first argument
an "id"
this id uniquelly identifies the node in the tree.

The addAccumulator takes two "ids" of nodes, which will be the new
Node's sons.

So basically when I create a new "Accumulator" with
t.addAccumulator("5","3","4",AndOrTree.ACCUMULATOR.OR); I create a new
Node with identifier 5 that is a parent of nodes 3 and 4.

Now, I want to keep the same functionallity under customer Tags.
In my vision, it should look something like that:

<aot:condition id="1" operator="<" property="size" value="8" >
<aot:condition id="2" operator="<" property="cpu-time" value="85" >
<aot:accumulator id="3" name1="1" name2="2" ...>

Since there is a Tree out there, I guess I should also implement a tag
that initializes the tree
The tree should also be transferred to other tags for reference, so it
should be something like that:

<aot:tree id="myTree">
<aot:condition tree="myTree" id="1" operator="<" property="size"
value="8" >
<aot:condition tree="myTree" id="2" operator="<" property="cpu-time"
value="85" >
<aot:accumulator tree="myTree" id="3" name1="1" name2="2" ...>

I "extended" TagSupport and did the previous bit of
tree.addCondition(this.id,this.operator,this.property,this.value)
inside the doStartTag () function.
My problem is with the TreeTag, How can I implement and extended
TagSupport that will have a reference to a AndOrTree that I can later
set as a member of the other Tag classes?

My tag handlers looks like that:
public class ConditionTag extends javax.servlet.jsp.tagext.TagSupport{

    //For the  TLD calls;
   private String property;
   private String operator;
   private String value;
   private AndOrTree tree;

   /** Creates a new instance of ConditionTag */
   public ConditionTag() {
   }
      public void setOperator(String operator) {
       this.operator = operator;
   }

   public String getOperator() {
       return operator;
   }

   public String getValue() {
       return value;
   }

   public String getProperty() {
       return property;
   }

   public void setValue(String value) {
       this.value = value;
   }

   public void setProperty(String property) {
       this.property = property;
   }

   public AndOrTree getTree() {
       return tree;
   }

   public void setTree(AndOrTree tree) {
       this.tree = tree;
   }

   public int doStartTag ()
   {

tree.addCondition(this.id,this.operator,this.property,this.value);

       return SKIP_BODY;
   }

  public int doEndTag()
   {
       return EVAL_PAGE;
   }

 
}

How should I implement the TreeTag class?
Thanks.
