问题描述:
我想用Wrapper做java后台服务器程序，Wrapper配置完毕，但是运行App.bat时，提示如下错误：
wrapper | -->WrapperStarted as Console
wrapper | Launching a JVM...
jvm 1 | Wrapper(Version 3.2.1)wrapper.tanukisofarejvm 1 |
jvm 1 |
jvm 1 | WrapperSimpleApp:Encountered an error running main:javang.illegalAccessException:Class .tanukisofare.wrapper.WrapperSimpleApp can not access a member of class A with modifiers "public static"

jvm 1 | at javang.Thread.run(Unknown Source)
wrapper | 《--Wrapper Stopped
请按任意键继续...
请问这是怎么回事，如何解决？是否对类的写法又要求，是否有Main方法?
我的程序目录为：
|-bin-+
| |-wrapper.exe
| |-UninstallApp-NT.bat
| |-App.bat
| |-InstallApp_NT.bat
| |-A.class
|
|-conf-+
| |-wrapper.conf
|
|-logs-+
| |-wrapper.log
|
|-lib-+
|-wrapper.dll
|-wrapper.jar
以下是A.class的内容：
import javax.swing.*
import java.awt.*
import java.awt.event.*
import java.sql.*
/*引用短信类*/
class A extends JFrame{
private String url = "jdbc:mysql127.0.0.1:3306/test"
private String user = "root"
private String pass = ""
private String content,phones
private String[] tels
private int sdid
private Connection conn,delConn
private Statement sql
private ResultSet rs
A(){
super("短信发送系统")
/*短信注册代码 实例化短信类*/
this.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
/*短信注销代码*/
System.exit(0)
}
})
}
public void runA(){
try{
Class.forName(".mysql.jdbc.Driver")
}catch(ClassNotFoundException e){
System.out.println(e)
}
try{
conn = DriverManager.getConnection(url,user,pass)
sql = conn.createStatement()
rs = sql.executeQuery("SELECT * FROM ok")
while(rs.next()){
sdid = rs.getInt(1)
content = rs.getString(3)
phones = rs.getString(6)/*发送短信代码*/
}
}
rs.close()
sql.close()
conn.close()
}catch(SQLException sqle){
System.out.println(sqle)
}
}
public static void main(String[] args){
A a = new A()
a.runA()
}
}
请高手帮忙指点谢谢！
解析:
新建一个类,把A类主方法写到这个类中.
在Windows中，无法直接用Java产生Service程序；但是可能通过编写DCOM 或 MTS COM 或 COM+(Window2000) 组件 或 Corba 来模拟Service程序，可以实现透明远程过程调用；StdAfx.h
