When the Submit.jsp form is complete it is passed to the ProcessForm.jsp
(Inserted to db)
Thus i have created a UserInfoValid.jsp as below. I now that i should'nt
use script albeit i need something to demostrate my keep.
jsp:useBean id="planBean" scope="session" class="PlanBean" />
<jsp:setProperty name="planBean" property="statusMsg"/>
<%! boolean valid = true ; %>
<% if ((planBean.getFirstName()).equals("")) { valid = false ;
planBean.setStatusMsg(planBean.getStatusMsg() + "Please enter
your First Name "); } %>
<% if ((planBean.getLastName()).equals("")) { valid = false;
planBean.setStatusMsg(planBean.getStatusMsg() + "Please enter
your Last Name "); } %>
<% if ((planBean.getAddress()).equals("")){valid = false;
planBean.setStatusMsg(planBean.getStatusMsg() +"Please enter
your Address "); } %>
<% if ((planBean.getEmail().equals(""))){ valid = false;
planBean.setStatusMsg(planBean.getStatusMsg() +"Please enter
your Email Address "); } %>
<% if ((planBean.getObservation()).equals("")){ valid = false;
planBean.setStatusMsg(planBean.getStatusMsg() +"Please enter
your Comments "); } %>--%>
<% if (valid) { %>
<jsp:forward page="ProcessForm.jsp" />
<% } else { %>
<jsp:forward page="Submit.jsp" />

RE: Any suggestions Prob with validation be passing to db
Posted by Lou Farho <lo...@certes-solutions.com>.
One needs to validate the data on the form before submitting to
the server. Usually one uses javascript to perform this task.
Put the javascript into a file and include it in the page.
Once on the server the data should be validated again to prevent attacks
from
hackers. That's were the Struts form comes in. One can use the validate
method
to re-validate input.
The above is just to make sure we don't waste time going to the database or
any EJBs, etc.
Then there may be the validation of data against the business model or data.
This is where we apply the business logic and perform any database related
tasks.
Here are some good resources:
