小编Kan*_*gam的帖子

我得到错误,因为我在struts标签中使用占位符属性....

<html:text property="name" styleClass="form-control" placeholder="some text"/>

如何解决问题,请帮帮我.

提前致谢.

我是java开发人员.我正在开发新的应用程序框架.在这个应用程序中我将集成JBPM,spring和hibernate.

所以,请回答我的以下问题,

1. 什么是JBPM？
2. 为什么要用它？
3. 什么是工作流引擎？

请举一个例子.

感谢您的回答.

我在下面添加了代码和错误,请正确更改以下代码.我得到了NumberFormatException,我该如何解决它.

码:

try{
String balance1 = childNode.getChildText("Balance1");//For input string: "00000162968518794 "
System.out.println(balance1);
long ledgerBalance = Long.valueOf(balance1);
accountSummaryList.setLedgerBalance(ledgerBalance);
System.out.println(ledgerBalance);
}catch(NumberFormatException nfe){
nfe.printStackTrace();
}

输出:
