import java.io.*;

public class FileTag extends SimpleTagSupport {
    private String fileName;
    public void setFileName(String fileName)
    {
    	this.fileName=fileName;
    }
    public void doTag() throws JspException, IOException
    {
    	BufferedReader in=new BufferedReader(new FileReader(fileName));
    	String temp="";
    	String fileContent="";
    	while((temp=in.readLine())!=null)
    	fileContent+=temp;
    	in.close();
	    getJspContext().getOut().write( "<table border=1><tr bgcolor=9944cc><td>文件标签</tr></td><tr bgcolor=cc44cc><td>"+fileContent+"</td></tr></table>" );
