I have a javabean like :
package com.icsc.zzjj.client.bean;
import java.io.Serializable;
import java.lang.Float;
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.IdentityType;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class EmailBean implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
@Persistent
private String recMail;
@Persistent
private String sendMail;
@Persistent
private String sendDate;
@Persistent
private String sendTime;
@Persistent
private String recDate;
@Persistent
private String recTime;
@Persistent
private String sendName;
@Persistent
private String recName;
@Persistent
private String subject;
@Persistent
private String attachment;
@Persistent
private String context;
@Persistent
private String status;
public Long getId() {
return id;
}
public String getRecMail() {
return recMail;
}
public void setRecMail(String recMail) {
this.recMail = recMail;
}
public String getSendMail() {
return sendMail;
}
public void setSendMail(String sendMail) {
this.sendMail = sendMail;
}
public String getSendDate() {
return sendDate;
}
public void setSendDate(String sendDate) {
this.sendDate = sendDate;
}
public String getSendTime() {
return sendTime;
}
public void setSendTime(String sendTime) {
this.sendTime = sendTime;
}
public String getRecDate() {
return recDate;
}
public void setRecDate(String recDate) {
this.recDate = recDate;
}
public String getRecTime() {
return recTime;
}
public void setRecTime(String recTime) {
this.recTime = recTime;
}
public String getSendName() {
return sendName;
}
public void setSendName(String sendName) {
this.sendName = sendName;
}
public String getRecName() {
return recName;
}
public void setRecName(String recName) {
this.recName = recName;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getAttachment() {
return attachment;
}
public void setAttachment(String attachment) {
this.attachment = attachment;
}
public String getContext() {
return context;
}
public void setContext(String context) {
this.context = context;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
}
my Service-----
GmailServiceImpl:
public List<EmailBean> findMail(String key) {
PersistenceManager pm = PMF.get().getPersistenceManager();
Query query = pm.newQuery(EmailBean.class);
query.setFilter("status == statusParam && recMail == recMailParam
");
query.setOrdering("id asc");
query.declareParameters("String statusParam,String
recMailParam");
Map args = new HashMap();
args.put("statusParam", key);
args.put("recMailParam", "[email protected]");
List<EmailBean> results = (List<EmailBean>) query.executeWithMap
(args);
return results;
}
for gwt rule, the bean must be implements Serializable
but when GmailServiceImpl. findMail is called ,the exception throw as
follow:
javax.servlet.ServletContext log: Exception while dispatching incoming
