jbpm教程（二）创建公文 并把公文与流程定义文件相互绑定

package com.sxito.jbpm;

public class Document {
private int id;
private String title;
private String context;
private long processInstanceId;

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getContext() {
return context;
}
public void setContext(String context) {
this.context = context;
}
public long getProcessInstanceId() {
return processInstanceId;
}
public void setProcessInstanceId(long processInstanceId) {
this.processInstanceId = processInstanceId;
}
}
