Hi,
is there is a way to implement validation using JSP block in form using the form variable.
e.g)
Mobile number must be 10 digits
in var1 as text field which takes the mobile number as input
in var2 whether we can use the java script to restrict the var1 for the validation process.
if yes? how can we achieve that ?
You can use field level validation for this.
jsp can contain...
<%
String name = request.getParameter("name");
String question = request.getParameter("question");
String value = request.getParameter("value"); //contains var1 value
if (//logic to check phone number format...) {
out.println("Invalid phone number for " + question + ", expected (###) ###-####");
}
%>
upload jsp under.. Admin -> User Interface -> files.
Once you have uploaded script using the above method, you can reference the script using the uri:
/aveksa/custom/jsp/<your validation form>.jsp
I can achieve using jsp files but is there a way to achieve it directly in the form variables through hidden fields instead of uploading .jsp files
How to perform Form Level validation i have got the example but unable to crack that
I have used this
<%@ page import="java.util.Enumeration" %>
<%@ page import="java.util.HashMap" %>
<%@ page import="java.util.Properties" %>
<%@ page import="java.io.ByteArrayOutputStream" %>
<%
HashMap<String, String> values = new HashMap<String, String>();
HashMap<String, String> questions = new HashMap<String, String>();
// Make the parameters and questions easy to access
for (Enumeration e = request.getParameterNames(); e.hasMoreElements();) {
String name = e.nextElement().toString();
String value = request.getParameter(name);
if (name.startsWith("value.")) values.put(name.substring(6), value);
if (name.startsWith("question.")) questions.put(name.substring(9), value);
}
System.out.println("validateform.jsp request method=" + request.getMethod());
System.out.println("validateform.jsp parameterMap=" + request.getParameterMap());
System.out.println("validateform.jsp values=" + values);
System.out.println("validateform.jsp questions=" + questions);
Properties outputProps = new Properties();
if (!values.containsKey("v2")) {
outputProps.put("error","Where is the v2 field!");
} else if (!values.get("v2").contains("Demo")) {
outputProps.put("error.v2","I am expecting the word Demo here");
outputProps.put("error","Form validation failed!");
}
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
outputProps.store(outputStream, null);
outputStream.close();
out.print(outputStream.toString("ISO-8859-1"));
%>
but it throws some error and its not working
Could anyone help on this ?
what are the variables to declare to proceed in form
Hello,
Please refer the below section,
<%@ page import="java.util.Enumeration" %>
<%@ page import="java.util.HashMap" %>
<%@ page import="java.util.Properties" %>
<%@ page import="java.io.ByteArrayOutputStream" %>
<%
HashMap<String, String> values = new HashMap<String, String>();
HashMap<String, String> questions = new HashMap<String, String>();
// Make the parameters and questions easy to access
for (Enumeration e = request.getParameterNames(); e.hasMoreElements();) {
String name = e.nextElement().toString();
String value = request.getParameter(name);
if (name.startsWith("value.")) values.put(name.substring(6), value);
if (name.startsWith("question.")) questions.put(name.substring(9), value);
}
Properties outputProps = new Properties();
if (!values.containsKey("v2")) { //This line will check for 'v2' variable in enum set, v2 is the field variable
outputProps.put("error","Where is the v2 field!"); // This will print the error on the form, top left corner
} else if (!values.get("v2").contains("Demo")) { //values.get(v2) will get you the value entered for 'v2' field
outputProps.put("error.v2","I am expecting the word Demo here"); //prints error msg on top of field in the form
outputProps.put("error","Form validation failed!");
}
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
outputProps.store(outputStream, null);
outputStream.close();
out.print(outputStream.toString("ISO-8859-1"));
%>
So, using get method fetch the values from field and perform logic which meets your reqmnts, and you can print error msg accordingly.
you can also the test the form by entering dummy/constant values for variables, use below url to run
http://localhost:8080/aveksa/custom/jsp/<filename>.jsp
Hi Tahir,
I am getting below error message
ERROR [com.aveksa.gui.ExternalValidation] Error 404 on e xternal validation of form http://localhost:8080/aveksa/custom/jsp/Validateform. jsp
just to be clear, localhost should be ip/fqdn of aveksa server.
Also, can you post your jsp file here.
Yes ,I have used the ip address but still not showing anything .
i have created v2 field with text field .
I have used the same jsp file which you posted have not changed anything.
Revanth,
I just tested with same code, I'm able to get it through successfully. as per code, it expecting word 'Demo' in v2 field.
Please check validation uri on form, it should be /aveksa/custom/jsp/v2.jsp
Thanks it worked
The problem is with path it is not taking /aveksa/custom/jsp/v2.jsp and so i have change the path and it worked .
Thnks for the much needed help
Hi Tahir,
But Form level validation is not working for Entitlement table .
when i try to pre populate the selected entitlement in a text field and it also not happening
is it a bug or any other solution is there?
You can use field level validation for this.
jsp can contain...
<%
String name = request.getParameter("name");
String question = request.getParameter("question");
String value = request.getParameter("value"); //contains var1 value
if (//logic to check phone number format...) {
out.println("Invalid phone number for " + question + ", expected (###) ###-####");
}
%>
upload jsp under.. Admin -> User Interface -> files.
Once you have uploaded script using the above method, you can reference the script using the uri:
/aveksa/custom/jsp/<your validation form>.jsp
