How to validation validation on different form fileds

Hi All,

In The following screen shoot if i will select doctor name and appointment date fields. I need to do validation like a doctor should not have two appointments for same time. for this i went for custom validation adaptor i wrote code sbo like the following way .

public boolean validateDate(Date date) throws AdaptorException {

//here am writing the validation logic.

}

But the problem is am not able to get doctor_name filed value in this validateDate sbo. Is there any way to do this.

Thanks

Hi,

You can not get values for the fields using Validator adaptor. As mentioned by "Karthik Chokkaraman" you need to implement Document Validator.

I am attaching a sample code below, that shows how to take element values and validate them.

 public class ValidateExtendedDate implements IDocumentValidator {            public boolean validate(Document document) throws XFormsProcessorException{                        String isExtended = document.getElementsByTagName("isExtended").item(0).getTextContent().trim();            //"isExtended" is element name, replace it with your form-element data model element varible name                System.out.println("isExtended : " + isExtended); // printing value of field                        boolean validate = false;              // implement your validation logic here            return validate;        }        public void destroy() throws AdaptorException {        }        public void init(IAdaptorConfiguration arg0) throws AdaptorException {        }    }

Hope it helps

I am assuming that you are using Item Validator. Instead, implement a Document Validator so that you will gain access to all the items in the screen. If you use Item Validator on the Appointment Date field, you will be able to get the appointment data value only and not the other fields.

Hi Sagar,

Thanks for your replay. am implementing the sbo as you said. but the problem is, it is giving exception like

com.documentum.tools.adaptor.AdaptorException: java.lang.ClassCastException: com.iit.docvalidate.HMSDocValidationImpl cannot be cast to com.documentum.fc.client.IDfModule.

is there any other interfaces do i need to implement.

Explain the packaging steps and the way you configured the SBO in composer. What did you choose as implementation/interface jar and what they have.

This exception occurs where there is something wrong in the way you packaged and created the artifact. Some details below:

If you created a BOF module that implements an interface and package the interface in an implementation JAR file:

a) The interface that is packaged in the implementation JAR resolves to the module-specific class loader because it is parent last

b) Your client application instantiates the BOF module and tries to cast it to the interface. It uses the interface that is loaded by the client application class loader, because there is no way for your application to reference the interface in the module class loader (the parent class loader cannot see children class loaders)

c) Java throws ClassCastException, because it expects the interface that was loaded by the module-specific class loader to be used to cast the BOF module, but you are using the one that was loaded by your application class loader. Alternatively, if you correctly package the interface inside an interface JAR file, it is loaded by the shared BOF class loader, which is parent-first. The interface resolves to its parent class loader first (your application’s class loader), and no exception is thrown
