I'm new to Struts and just playing around with sample applications. I have a very simple jsp :

The jsp simply checks if a request parameter "id" has a value of 2 and then prints Yes or No accordingly. However, my jsp always prints no. Is there a right way to check for request parameter values? Should this check be in the Action instead of the jsp?

use the following instead:

<body>Id is : <s roperty value="%{#parameters.id[0]}" /><br /><s:if test="%{#parameters.id[0] == 2}">Yes</s:if><s:else>No</s:else>
</body>

The parameters are passed as an array Map<String,String[]> and not Map<String,String>

The reason behind this is we can pass multiple parameters with same name.

The reason is the amount of satisfaction which we get through food is of only one minute or two. But the satisfaction which we can get through the knowledge is of life long.

Without subsidies, chem-ag food costs four times more than organic. Or this tiny ad:
