The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Duplicat entries in an Arraylist where data was fed in from a resultSet

Asked by aman0711 in New to Java Programming, Java Server Pages (JSP), Java Programming Language

Tags: Java

Hi Experts,
I have an Arraylist which contains some text entries fed to it from the Database.

In my jsp page, I have javascript text slideshow which displays the content of this ArrayList.
My database table has 10 rows(10 messages), where as on my jsp page, every entry is duplicated 13 times. so all together 130 entries.

Where am I going wrong.

Below is the small piece of code from my JSP, where I loop over the ArrayList

<script type="text/javascript">
var count = 0;
var notes = new Array();
<c:forEach items="${notes}" var="current" varStatus="status">
notes[${status.count - 1}] = "${current}";
</c:forEach>
