I have a problem with a managed bean in a JSF app deployed on JBoss 4.0.3. When
I refer to it in a jsp like:
| <h:outputText value="#{correspondor.newCorrespondence}"/> <% /* for side
effect */%>
|
this exception is thrown:
| javax.servlet.ServletException: javax.servlet.jsp.JspException:
javax.faces.FacesException: javax.faces.FacesException: Can't instantiate
class: 'uk.gov.brightonhove.adaptability.CorrespondenceBean'.. class
uk.gov.brightonhove.adaptability.CorrespondenceBean :

The bean compiles fine and is in the classpath of the war file when it's
deployed. It is referenced in faces-config like:
| <managed-bean>
| <managed-bean-name>correspondor</managed-bean-name>
<managed-bean-class>uk.gov.brightonhove.adaptability.CorrespondenceBean</managed-bean-class>
| <managed-bean-scope>request</managed-bean-scope>
| </managed-bean>
|
the bean looks like
| package uk.gov.brightonhove.adaptability;
|
| import java.util.Date;
| import java.util.Iterator;
| import java.util.List;
|
| import javax.faces.application.FacesMessage;
| import javax.faces.context.FacesContext;
| import javax.faces.model.SelectItem;
|
| import uk.gov.brightonhove.adaptability.dao.CorrespondenceDao;
| import uk.gov.brightonhove.adaptability.dao.ProjectTaskDao;
| import uk.gov.brightonhove.adaptability.dao.TaskTemplateDao;
| import uk.gov.brightonhove.adaptability.pojo.Correspondence;
| import uk.gov.brightonhove.adaptability.pojo.ProjectA;
| import uk.gov.brightonhove.adaptability.pojo.ProjectTask;
| import uk.gov.brightonhove.adaptability.pojo.TaskTemplate;
|
| public class CorrespondenceBean extends BaseBean {
|
| private Correspondence correspondence;
| private ProjectTask task;
| private boolean disabled;
| private HomeBean home;
| private ProjectA project;
|
| public CorrespondenceBean() {
| home = (HomeBean)getAdaptBeanBinding("#{homer}");
| newCorrespondence();
| }
|
| protected void newCorrespondence() {
| disabled = false;
| correspondence = new Correspondence();
| task = home.getChosenTask();
| project = task.getProject();
| getFormLettersForTask();
|
correspondence.setTemplateid((Short)formLettersForTask[0].getValue());
| if (task.getDate_completed() == null) {
|
correspondence.setProjecttaskid(task.getProjectTaskId());
| } else {
| disabled = true;
| // correspondence = new
CorrespondenceDao().getCorrespondence()
| System.out.println("todo");
| }
| }
| //snip
| }
|
why is my bean not found? TIA
