Putting Java code in a JSP is a bad practice that's been obsolete for 15 years. Secondly, if you want to make sure that at least one checkbox is returned, why not just check the array length for zero? Just be aware that in the professional world, putting Java code in a JSP is not acceptable. Just be aware that in the professional world, putting Java code in a JSP is not acceptable. I do wonder if it's some PHPish throwback that results in JSPs being taught first, and then they never update their course notes. :) It's not uncommon, sadly, so I'm not sure how much blame can be laid at the teacher, rather than the course material in general. They should start with servlets, then bolt on JSPs after a functioning "Hello World" has been written. The answer should be available in the API for javax.servlet. If the parameter has a single value, the array has a length of 1. As you are hinting, the initial error you were getting from your code would have been a null pointer exception from trying to access the array of checkbox results when no checkboxes were ticked.

mammshean santiez, I have merged your topic into this topic. EDIT: Please don't ask the same question again on another forum here. I do wonder if it's some PHPish throwback that results in JSPs being taught first, and then they never update their course notes. Whenever i leave all of the checkbox unchecked it gives me error, if i check at least one it doesnt. There should have been a stacktrace pointing you at which line was going wrong.

These are the cmdlets the module exposes: The alias for parameter.

The default output will be to list the properties, but since it is now a collection of objects, you can choose to output it to a table, to a grid view, or export to a file, using the appropriate cmdlets.

The benefit of the module is that it negates the need to create an Outlook profile for the owner/manager in order to manipulate his or her delegates.

The module requires any version of the EWS Managed API and the Exchange cmdlets via remoting, as detailed below.

My questions from before still stand: What values do you get when you try this out? There should have been a stacktrace pointing you at which line was going wrong.

You're best off doing whatever is needed to get you through the subject, first, sadly.

Is this checking for required fields or do the values matter as well? Just for future reference when making a post it helps to use Code Tags There is a handy button for it on the interface.

You can also use these output cmdlets to select only the properties you want.
