Document Validator - java.lang.ClassCastException

Hosam Salem

Dear All,

I created a document validator as an SBO, deployed the validator on the repository, and used it as the document validator for my form.

But, when i run the form and click on any button, i get the following error message:

com.documentum.tools.adaptor.AdaptorException: java.lang.ClassCastException: org.bibalex.cms.hrApps.bof.modules.sbo.LeaveRequestValidator cannot be cast to com.documentum.xforms.engine.adaptor.IServiceAdaptorMSG_ERR_FORM_INVALID

The interface code for the module is:

package org.bibalex.cms.hrApps.bof.modules.sbo;import com.documentum.fc.client.IDfService;import com.documentum.xforms.engine.adaptor.IServiceAdaptor;import com.documentum.xforms.engine.adaptor.validator.IDocumentValidator;import org.w3c.dom.*;import com.documentum.xforms.engine.*;public interface ILeaveRequestValidator extends IDfService,IServiceAdaptor,IDocumentValidator {    public boolean validate(Document document)    throws XFormsProcessorException;}

And the implementation code for the module is:

package org.bibalex.cms.hrApps.bof.modules.sbo;import java.text.DateFormat;import java.util.Date;import org.w3c.dom.*;import com.documentum.tools.adaptor.AdaptorException;import com.documentum.tools.adaptor.configuration.IAdaptorConfiguration;import com.documentum.xforms.engine.*;import com.documentum.xforms.engine.adaptor.IServiceAdaptor;import com.documentum.xforms.engine.adaptor.validator.*;import com.documentum.fc.client.DfService;import com.documentum.fc.client.IDfService;import java.text.*;public class LeaveRequestValidator extends DfService implements IDocumentValidator,IServiceAdaptor,IDfService {    public void init(IAdaptorConfiguration adaptor)    throws AdaptorException    {}    public void destroy() throws AdaptorException    {}    public boolean validate(Document document)    throws XFormsProcessorException    {        boolean result = true;        DateFormat formatter ;        Date dStartDate,dEndDate;        String strStartDate,strEndDate;                strStartDate = document.getElementsByTagName("leave_start_date").item(0).getTextContent().trim();        strEndDate = document.getElementsByTagName("leave_end_date").item(0).getTextContent().trim();                formatter = new SimpleDateFormat("MMM dd,yyyy");                try        {            dStartDate = (Date)formatter.parse(strStartDate);            dEndDate = (Date)formatter.parse(strEndDate);            if(dEndDate.compareTo(dStartDate)<0)            {                result = false;            }        }         catch (ParseException e)          {            System.out.println("Exception :"+e);          }                 return result;    }    @Override    public void setDocbaseName(String arg0) {        // TODO Auto-generated method stub            }}

Can anyone explain what if the cause of this issue?

Thanks in advance.

Instead of implementing as SBO, have you just tried to implement using the syntax in the Forms Builder Development guide.  Here's sample class:

public interface IDocumentValidator extends IAdaptor {

public boolean validate(Document document)

throws XFormsProcessorException;

}

public class SampleDocumentValidator implements IDocumentValidator{}
