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.

How does iBatis and Spring dataSource communicate?

Asked by MehtaJasmin in Spring, Java Programming Language, J2EE Frameworks

Tags: iBatis, Spring, Java Framework, Transaction, Rollback

Does the datasource get related from SqlMapConfig.xml (iBatis) with spring.xml ? Also I have data-source.xml file within META-INF folder of my project.

I have not defined dataSource bean in spring.xml thinking that iBatis layer has already done that. Is it must to define dataSource in spring.xml in order to have rollback working? Can you view my code snippet and she what needs to be fixed ?
