Liferay Portlet development with Spring: "PortletException: No adapter for handler"

[Christian Esocidae]

Hello,

I am getting the following error message after deploying the portlet to liferay. You will also find the involved controller as well as the config file.

Tools and technology in use:
Netbeans Portal Pack 3
Glassfish 2.1
Liferay Portal Standard Edition 5.2.3
Spring 2.5 Portlet MVC Framework

The error message:

  
[AutoDeploy] Successfully autodeployed : C:\Programme\glassfish\domains\domain1\autodeploy\MontyBrogan.war.

The controller:

    

package Controller;

import Dao.AssignmentDao;
import Model.Assignment;
import java.text.SimpleDateFormat;
import java.util.Date;
import javax.portlet.PortletRequest;
import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.web.portlet.bind.PortletRequestDataBinder;
import org.springframework.web.servlet.mvc.SimpleFormController;

public class AssignmentFormController extends SimpleFormController {

    private AssignmentDao assignmentDao;

    public void setAssignmentDao(AssignmentDao assignmentDao) {
        this.assignmentDao = assignmentDao;
    }

    public AssignmentFormController() {
        //Initialize controller properties here or
        //in the Web Application Context

        setCommandClass(Assignment.class);
        setCommandName("assignmentForm");
        //setSuccessView("successView");
        //setFormView("formView");
    }

    protected void initBinder(PortletRequest request, PortletRequestDataBinder binder) {
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
        dateFormat.setLenient(false);
        binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
    }

    @Override
    protected void doSubmitAction(Object command) {
        Assignment assignment = (Assignment) command;
        assignmentDao.store(assignment);
    }

}

The config file:

    
<?xml version="1.0" encoding="UTF-8"?>

        <property name="formView" value="assignmentForm"/>
        <property name="successView" value="assignmentSuccess"/>
    </bean>

</beans>

Thanks in advance.

Hello,

this problem is still an issue. I have no idea why the DispatcherPortlet does not work propper. Any hint to solve the problem would be appreciated.

Thanks

Christian
