I have data validation by JS. Now I want to write another set's data input validation by java, not java script - server-side validation. How can I do that?
Here are my input parameters
<form class="portlet-generic-con
tainer" style="clear:left;" name="NetFlow" action="<portlet:actionURL
/>" method="post" onSubmit="return ValidateForm()" >
<div class="portlet-generic-con
tainer" style="padding-top:5px;pad

<label class="portlet-form-label"
style="color:black; size:medium">Type</label>
</legend>
<input name="VolContID" type="hidden" value="999" >

Here are the inputs I need to do server-side validation in java
1. Degree of Imbalance:<input name="DegImb" type="text">, must be an integer value
2. Min. Flows Per Hour: <input name="TotalFlowImb" type="text">, must be an integer value
3. # of Results: <input type="text" name="Num_Results">, must be an integer value
4. Begin Date <input type="text" size="10" maxlength="20" name= "BegDate"> must be a date value
5. End Date <input type="text" size="10" maxlength="20" name="EndDate" > must be a date value
6. begtime <select name="begtime">, must be time value
7. <select name="endtime">, must be a time value
I want to do validation above by java. in the code, if not the value, throw out an exception. I want to do the
try....
cath....
Can anyone give me sample code about above?
Thanks
