NetBeans 有问必答活动 - 2008/10/27
- 1:【有问必答】请问怎样reset netbean新增Project时的预设号码?
请问要怎样reset那个default的号码啊? 现在都累积到24了, 有办法reset回1吗?

Michael: 两个办法，把项目生成的根目录换个新的，或者，把老项目删去，NetBeans就会重新计数。
- 2:【有问必答】netbeans web服务返回对象
在netbeans中选择建立java类如下：
package org.me.calculator;
import java.io.Serializable;
/**
-
- /
public class CustomerInfo implements Serializable{
private String customerName;
private int customerAge;
public String getCustomerName() {
return customerName;
}
public void setCustomerName(String customerName) {
this.customerName = customerName;
}
public int getCustomerAge() {
return customerAge;
}
public void setCustomerAge(int customerAge) {
this.customerAge = customerAge;
}
public CustomerInfo(String customerName,int customerAge)
{
this.customerName=customerName;
\
this.customerAge=customerAge;
}
}
在netbeans中，选择从头开始建立web服务文件，CustomerService,代码如下:
/*
- To change this template, choose Tools | Templates
- and open the template in the editor.
- /
package org.me.calculator;
import javax.jws.WebMethod;
import javax.jws.WebService;
/**
-
- /
@WebService()
public class CustomerService {
/**
* Web 服务操作
*/
@WebMethod(operationName = "GetCustomer")
public CustomerInfo GetCustomer() {
//TODO 在此处编写实现代码：
return new CustomerInfo("china",1);
}
}
生成可以通过，运行时候，输出框出现如下消息:

- 3:【有问必答】J2ME开发时的问题
代码如下：
// open an input stream to the file
FileInputStream fis = new FileInputStream("F:/wks/Certificate/client-cert.pem";
// instantiate a CertificateFactory for X.509 CertificateFactory cf = CertificateFactory.getInstance("X.509";
// extract the certification path from
// the PKCS7 SignedData structure
CertPath cp = cf.generateCertPath(fis, "KCS7";
异常如下：
IOException parsing PKCS7 data: sun.security.pkcs.ParsingException: ObjectIdenti
fier() -- data isn't an object ID (tag = 4
提前多谢各位。
