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!

You can use struts DispatchAction for the same..

Which allows you to call different operations depending on the different values for a prameter

sanjooz:
You can use DispatchAction as mentioned by cmalakar. If you already have written your action class, then you can find out the value of the button pressed, which is also passes along with rest of the form and then depending on that value, you can internally call different functions.

drazen_nikolic:
You can also create a new property in your form bean, e.g. String submitType, and give this property to all of your submit buttons. So, you will have:
<html:submit property="submitType" value="ADD"></html:submit>
<html:submit property="submitType" value="next"></html:submit>
<html:submit property="submitType" value="cancel"></html:submit>

Than, after the form is submitted, you your action, mapped with "/project.do" you can check action type by reading action form attribute submitType.

All other properties of html:submit you can see at:
http://struts.apache.org/1.2.x/userGuide/struts-html.html#submit

But, as previous comments pointed out, it is more efficient to use some kind of DispatchAction. For example, you can use LookupDispatchAction (see the example in the API: http://struts.apache.org/1.x/struts-extras/apidocs/org/apache/struts/actions/LookupDispatchAction.html) or MappingDispatchAction (http://struts.apache.org/1.x/struts-extras/apidocs/org/apache/struts/actions/MappingDispatchAction.html).

Hope this helps.

My example clearly shows you how to write "struts-config.xml"..

In the example, just instead of link, replace button..
