[英]Java project is not running on tomcat server from tomcat manager after deploying war file to webapps?
[英]run the java class from war file in tomcat server
我已經在遠程tomcat服務器中上傳了一個war文件。在這里我必須解壓縮war文件。在這里我必須在瀏覽器中運行Demo java類。我該怎么辦?
這是Demo.java的保存路徑:
/ var / lib / tomcat7 / webapps / Example / WEB-INF / classes / com / testprops / ws
在這里,我必須運行以下方法:URL http://xx.xx.xx.xxx:8080/Example/意味着正在成功獲取這些頁面。請檢查以下內容: http : //screencast.com/t/DKZW1t9Z1
這是我的Demo.java:
public class Demo {
public String customerData(){
String customerInfo = "";
int a=10;
customerInfo = customerInfo + a;
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/android","androiduser","AN124@7#7");
//Find customer information where the customer ID is maximum
PreparedStatement statement = con.prepareStatement("SELECT * FROM xcart_customers");
ResultSet result = statement.executeQuery();
while(result.next()){
customerInfo = customerInfo + a + "&" + result.getString("login") + "&" + result.getString("password") + "&"+result.getString("firstname") + "&"+result.getString("email");
//Here "&"s are added to the return string. This is help to split the string in Android application
}
}
catch(Exception exc){
System.out.println(exc.getMessage());
}
return customerInfo;
}
}
如何在瀏覽器上運行Demo.java類,請幫助我。
那是因為您需要編寫一個運行代碼的servlet。 基本上,當您向上述給定鏈接發出請求時,它將調用Demo.java
類並給出輸出。
建議您首先學習有關servlet的一些基礎知識。 那應該有幫助。
所以有一個像
public void doGet(HttpServeletRequest r, HttpServletResponse s){
Demo demo = new Demo();
demo.run();//your Demo.java is invalid as all that try catch code needs to be inside a method
}
