我正在研究web应用程序.我在我的jsp上调用request.getContextPath(),但奇怪的是我得到了地址/streetshop.
然后我附加一些路径作为request.getContextPath() + "abc"和创建文件夹.
然后创建文件夹D://而不是我的webapplication文件夹.
请告诉我,我想上传一张图片web-application root/images/images.gif.
以下是我的程序......但是在session.connect()之后这不起作用
public static void main(String args[])
{
try {
String ftpHost = "XXXXXXXX";
int ftpPort = 21;
String ftpUserName = "XXXX";
String ftpPassword = "XXXXX";
String ftpRemoteDirectory = "/";
String fileToTransmit = "C://XXXXX//Desktop//RG//10171699_821972117859158_5724612734096298046_n.jpg";
JSch.setLogger(new MyLogger());
System.out.println("Creating session.");
JSch jsch = new JSch();
Session session = null;
Channel channel = null;
ChannelSftp c = null;
//
// Now connect and SFTP to the SFTP Server
//
try {
// Create a session sending through our username and password
session = jsch.getSession(ftpUserName, …我从我的weblogic 8.1环境中复制了一个代码,并在我的新环境weblogic 10.3.4中复制.以下代码安静在我的8.1环境中工作.当我使用相同的代码时,它给了我下面的例外.

log.info("creating SAXBuilder");
Document document = saxBuilder.build(xmlPath);

public void doSth()
{
//logic
ClassName.staticMethod();
//logic
}
在我的应用程序中,有很多次将调用此函数.只有特定的行才会改变.我决定提供一个共同的功能.
现在我的问题是:如何在函数参数中传递ClassName,以便函数体动态地使用它？
谢谢
我正在阅读有关Pass by Value和Pass的参考资料,我得到了很多文章,其中一些人说Java只遵循'按值传递',其中一些说原始和对象之间存在一些差异.所以我写了下面的示例代码并且还要输出.请评论和分享答案是什么.
我检查了Int,String,StringBuffer和Employee类,现在它仅作为Employee类的引用传递.
package test;
class Emp {
public String name="";
public int age=0;
public Emp(String name, int age) {
super();
this.name = name;
this.age = age;
}
public String toString() {
return "Name: "+ this.name + "....Age: "+ this.age;
}
}
public class Class1 {
public Class1() {
super();
}
public void doChange(int i) {
i = i +10;
System.out.println("Value of Integer in Method:>"+ i);
}
public void doChange(Emp i) {
i.age=29;
i.name="rishu";
System.out.println("Value of Employee In Method …
