Hello Struts users,
I am new for the struts 2 and i have some problem with param setting. I
develop a simple action to view user detail: UserViewAction this action have
only a execute method, loading a user by userId param. So the action work
fine, but the jsp page do not display anything.
Follow my code:
package it.filosganga.sic.business;
import java.beans.PropertyChangeListener;
import java.beans.PropertyChangeSupport;
import java.io.Serializable;
import java.util.*;
import org.apache.commons.lang.builder.*;
import
org.springmodules.validation.bean.conf.loader.annotation.handler.NotBlank;
import
org.springmodules.validation.bean.conf.loader.annotation.handler.NotNull;
/**
* Classe che rappresenta un utente del sistema
*
* @author Filippo De Luca
* @version 0.2.00, 1/05/2006
*/
public class User implements Serializable {
/** serial */
private static final long serialVersionUID = 200L;
private Long id;
private Long version;
@NotNull
@NotBlank
private String username;
@NotNull
@NotBlank
private String password;
@NotNull
private boolean enabled;
@NotNull
private Date expire;
@NotNull
private Date credentialsExpire;
private Set<Role> authorities = new HashSet<Role>();
private final PropertyChangeSupport pcs = new
PropertyChangeSupport(this);
public User() {
/* Empty */
}
...
}
***
public class UserViewAction {
/** serial */
private static final long serialVersionUID = 1L;
private static final Log log = LogFactory.getLog(UserViewAction.class);
private UserService userService;
private Long userId;
private User user;
/**
* @return the userService
*/
public UserService getUserService() {
return userService;
}
/**
* @param userService
* the userService to set
*/
public void setUserService(UserService userService) {
this.userService = userService;
}
/**
* @return the id
*/
public Long getUserId() {
return userId;
}
/**
* @param id
* the id to set
*/
public void setUserId(Long id) {
this.userId = id;
log.debug("Setted id = " + id);
}
public String execute() {
user = userService.findUserById(userId);
log.debug("Loaded User = " + user);
return "success";
}
}

<package name="user" extends="struts-default" namespace="/User">
<default-interceptor-ref name="defaultStack"/>
<action name="list" method="execute" class="
it.filosganga.sic.web.actions.UserListAction">
<result>/User/list.jsp</result>
</action>
<action name="view" method="execute" class="
it.filosganga.sic.web.actions.UserViewAction">
<result>/User/view.jsp</result>
<interceptor-ref name="paramsPrepareParamsStack"/>
</action>
Some code are omitted for easy read. Can anyone help me?
in the past i develop a PreparableAction loading user in prepare method, but
i need to use paramsPrepareParamsStack to run it. What is the best way? load
user in execute method or in prepare method?
Best regards
