如何读取tomcat中<contex>里面的一个配置参数
<Context   path= "/eLink "  
  reloadable= "true "  
  docBase= "E:\Project\eLink "  
  workDir= "E:\Project\eLink\work "  
  SQLFile   =   "E:\Project\SQLFILE.xml "
  />
例如这样一个项目，我向读取   SQLFile参数，应该如何写代码？

关注中.
------解决方案--------------------
你要读取什么参数? 为什么不写在Parameter元素中呢

在哪个文件 的？Web.xml？

使用JDOM


import java.io.*;
import java.util.*;
import org.jdom.*;
import org.jdom.input.*;
import org.jdom.output.*;
import org.jdom.xpath.*;


public class jdomTool {

public static void main(String[] args) throws IOException, JDOMException {

String filename = "D://Web.xml ";
PrintStream out = System.out;

SAXBuilder builder = new SAXBuilder();
Document doc = builder.build(new File(filename));

// Print param information
XPath paramPath = XPath.newInstance( "//param ");
List param = paramPath.selectNodes(doc);
Iterator i = param.iterator();
while (i.hasNext()) {
Element servlet = (Element) i.next();
String paramname=servlet.getChild( "param-name ").getTextTrim();
if (paramname.equals( "SYSTEM_SMTP ")){
out.print(servlet.getChild( "param-value ").getTextTrim()+ "aa ");
}else if(paramname.equals( "SYSTEM_USER ")){
out.print(servlet.getChild( "param-value ").getTextTrim()+ "bb ");
}
}
}
}
