which util package would be useful to store Parent child relationship data in java
<p>I have a Tree structure like data from the database, there will be Single parent and to its multiple levels of childrens, </p>

<p>I am able to create the db table and store according to that structure, 
Now I need to display the data on to the jsp page.</p>

<p>My questions, which data strucuture would be more effective to traverse the data from DB to JSP page.</p>

<p>I am using DB2 database for that, I am not using Hibernate for this application, its just core java, jsp pages.</p>
