action代码不知道是不是这里出的错：

[code=java]	/**

	 * 处理用户申请请求

	 * 

	 * @return

	 */

	public String submit() {

		map = new HashMap<String, Object>();

		map.put("owner", processDto.getOwner());

		map.put("day", Integer.parseInt(processDto.getDay()));

		map.put("reason", processDto.getReason());

		map.put("name", processDto.getOwner());

		jbpmManager.complate(processDto.getTaskId(), map);

		return SUCCESS;

	}



定义的类型：
public class ProcessDto {

	private String taskId;

	private String owner;

	private String day;

	private String reason;

	

	public String getTaskId() {

		return taskId;

	}

	public void setTaskId(String taskId) {

		this.taskId = taskId;

	}

	public String getOwner() {

		return owner;

	}

	public void setOwner(String owner) {

		this.owner = owner;

	}

	public String getDay() {

		return day;

	}

	public void setDay(String day) {

		this.day = day;

	}

	public String getReason() {

		return reason;

	}

	public void setReason(String reason) {

		this.reason = reason;

	}

}

判断下是否为""或null，再转换。这还不具体吗？

Integer.parseInt(processDto.getDay())这个转换有问题，如果processDto.getDay()为空就包转换错误，判断下是否为""或null，再转换，这里的值必须是数字字符串。
ssh2+jbpm4.4 完整请假流程
自从前些日子发布了如何整合JBPM4.4+ssh2后，有些朋友问我有没有一个完整一点的实例，我看过贩卖你的jbpm的教程，我就参考那个请假的实例把它改装成ssh2版的吧。顺便也加入了模拟不同的角色登陆后能接到不同的待办...
jbpm的一个实例
JBPM是一个扩展性很强的工作...在这个版本里包括一个JBPM流程设计器的Eclipse插件，和一个用JBOSS作为服务器的示例流程等相关文件。解压jbpm-starters-kit-3.1.2.rar到某个特定目录，这里我们首先用到的是包里的JBPM目
jbpm-4.4.zip
jbpm-4.4.zip比较新的jbpm工具~~~
jbpm4.4实例
该资源是一个jbpm4.4的完整的例子 由于jar包太大 故没有上传jar 大家可以去 官网下载 如实在找不到也可以m我 我可以email给大家
jbpm4.4 jar 包下载

J2EE只是Java企业应用。我们需要一个跨J2SE/WEB/EJB的微容器，保护我们的业务核心组件（中间件），以延续它的生命力，而不是依赖J2SE/J2EE版本。
