Hi Jimmy,

I have the following values in database table LedgerGroup

GroupName GroupId ParentId
------------------------------------------------------------------------------------------------------
Asset 1 0
Current Assets 11 1
Cash-in-hand 111 11
Bank Accounts 112 11
Accounts Receivable 113 11
Fixed Assets 12 1
Furniture 121 12
Liability 2 0
Current Liability 21 2
Accounts Payable 211 21

------------------------------------------------------------------------------------------------------------
I referenced the follwing code in zkfiddle, but it creates static DefaultTreeNode. I want to create DefaultTreeNode based on the above database values hierarchy dynamically.

TreeModel model = new DefaultTreeModel(
new ImprovedTreeNode(null, new ImprovedTreeNode[] {
new ImprovedTreeNode("item 0", new ImprovedTreeNode[] {
new ImprovedTreeNode("item 00", new ArrayList()),new ImprovedTreeNode("item 01", new ArrayList())
}),
new ImprovedTreeNode("item 1", new ImprovedTreeNode[] {
new ImprovedTreeNode("item 10", new ArrayList()),new ImprovedTreeNode("item 11", new ArrayList())
}),
new ImprovedTreeNode("item 2", new ArrayList())
})
);


Could you please give me the psudeo code on the above sceneraio

Thanks

Abhi
